    This invention relates to a vehicle light comprising a range adjustment actuating device.
    In the prior art, a vehicle light is known which comprises a range adjustment actuating device configured to rotate a light unit, which is supported on a light body so that it can be pointed in one direction upper and lower and in a right and left direction, in the upper and lower direction, independently of a rotation by the pointing.
    Document JP-A-2006-315512 describes a configuration of the range adjustment actuator, in which an output shaft element supported on a main body of the actuator, which is fixed and supported on the light unit, to be movable in a front and rear direction of the light is arranged to protrude towards a rear light from the main body of the actuator.
    In the vehicle light described in document JPA-2006-315512, a pointing screw for pointing the light unit in the upper and lower direction is supported on the light body so that it can be turned around.

    Figure 1 is a front view showing a vehicle light 10 according to an illustrative embodiment of the present invention. Figure 2 is a sectional view along line II-II of Figure 1.
    In the drawings, a direction designated with a reference X is a "front" of a light ("front" of a vehicle), a direction designated with a reference Y is a "left direction" (a "direction left "of the vehicle; a" right direction ", as viewed from the front of the light) perpendicular to" the front ", and a direction designated with a reference Z is a" top direction ".
    As shown in Figure 1, the vehicle light 10 of the illustrative embodiment is a headlight disposed at a right front end portion of a vehicle, and has a configuration where a 20Ά light unit for low beam lighting and a 20B light unit for high beam lighting are housed side by side in a vehicle width direction in a fire chamber formed by a light body 12 and a translucent cover 14 which is transparent and is mounted on a front opening of the fire body.
    In the fire chamber, an extension panel 16 formed to surround the two fire units 20A, 20B is arranged in the vicinity of the front of the fire units. The extension panel 16 is formed with circular openings 16a to allow irradiation of light from the fire units 20A, 20B in positions corresponding to the respective fire units 20A, 20B.
    The two fire units 20A, 20B are supported on the fire body 12 via a common support 40.
    The support 40 is supported on the fire body 12 to be able to be rotated in an upper and lower direction and in a right and left direction through a pivot 42 positioned on an upper right side (an upper left side as seen from the front of the lamp) and two pointing screws 44, 4 6 positioned on an upper left side and a lower right side.
    Similarly, a range adjustment actuator 60 for rotating the two light units 20A, 20B in the upper and lower direction and the support 40, independently of a rotation by the pointing, is fixed and supported on the support 40.
    The two fire units 20A, 20B are all configured as a projector type fire unit.
    As shown in Figure 2, the light unit 20Ά for low beam lighting positioned on the right comprises a projection lens 22 having an optical axis Ax extending in the front and rear direction of the vehicle , a light emitting device 24 disposed behind a rear focal point F of the projection lens 22, and a reflector 26 arranged to cover the light emitting device 24 from above and configured to reflect the light from the light emitting device 24 towards the projection lens 22.
    The light emitting device 24 and the reflector 26 are supported on a base member 30, and the projection lens 22 is supported on the base member 30 via a lens holder 28 .
    The base member 30 is formed with an upward reflecting surface 30a configured to reflect upward part of the light reflected by the reflector 24 and to cause it to be incident on the projection lens 22 so as to form a cut-off line of a light distribution pattern for the low beam.
    A lower surface of the base member 30 is formed with a plurality of heat radiation fins 30b, so that the base member 30 functions as a radiator.
    The fire unit 20A is fixed and supported on the support 40 at the base element 30.
    At the same time, part of the configuration of the light unit 20B is different from the light unit 20A so as to produce a high beam light, but the other configuration is similar to the unit. of fire 20Ά.
    The support 40 extends in the vehicle width direction at the rear of the two light units 20A, 20B, and a lower end part thereof is formed with a lower wall part 40a configured to support the two light units 20A, 20B and extending towards the front of the light.
    The pivot 42 positioned on the upper right side in the fire chamber is arranged to extend in the front and rear direction of the fire, and a front end portion 42a is formed in a spherical shape. The pivot 42 is fixed and supported at its base end portion on the light body 12. The pivot 42 is engaged at the front end portion 42a with a spherical bearing 48 mounted on the support 40 of so that you can turn in all directions.
    The pointing screw 44 (see Figure 1) positioned on the upper left side in the fire chamber is arranged to extend in the front and rear direction of the fire, and is rotatably supported at its base end part (rear end part) on the light body 12. The pointing screw 44 is engaged in a screwed manner with a pointing nut 50 mounted on the support 40, in the vicinity of its front end. The pointing nut 50 is mounted on the support 40 in an aspect where the support 40 can rotate to a certain extent in the front and rear direction around a position engaged in a screwed manner B with the pointing screw 44.
    The pointing screw 46 positioned on the lower right side in the fire chamber is also arranged to extend in the front and rear direction of the fire, and is rotatably supported at its end portion of base (rear end part) on the light body 12. A pointing nut 52 to be screwed in with the pointing screw 46 is mounted in the vicinity of a front end of the pointing screw 46. L pointing nut 52 is supported on the
    support 40 by means of the range adjustment actuator 60.
    As shown in Figure 1, an engagement position A of the front end portion 42a of the pivot 42 and the spherical bearing 48 is at the same height as the screwed-in position B of the pointing screw 44 and the pointing nut 50. However, the engagement position A is moved towards the rear side of the light with respect to the screwed-in position B. Furthermore, a screwed-in position C of the pointing screw 46 and the pointing nut 52 is moved outward (to the right) in the vehicle width direction from a position located just below engagement position A.
    When pointing the two light units 20A, 20B in the upper and lower direction, since a central axis of rotation Lab becomes a line connecting the engagement position A and the engaged position screwed B, it becomes a line extending in a direction inclined towards the rear side of the lamp from the screwed in position B towards the engaged position A in a horizontal plane.
    On the other hand, when pointing the two fire units 20A, 20B in the right and left direction, a central axis of rotation Lac is a line extending in the vertical direction connecting the engagement position A and a coupling position D (which will be described later) located just below the engagement position A.
    Figure 3 is a detailed view of a part III of Figure 2, and Figure 4 is a detailed view of a part IV of Figure 2. Figure 5 is a sectional view along a line VV of Figure 4, and Figure 6 is a bottom view showing the pointing nut 52, with the reach adjustment actuator 60 and the support 40. Figure 7 is a perspective view showing main parts of the vehicle light 10, as seen from an oblique upper front part.
    As shown in the drawings, the range adjustment actuator 60 includes a main body of actuator 62 fixed and supported on the lower wall portion 40a of the support 40 and a shaft element outlet 64 supported on the main body of actuating device 62 to be movable in the front and rear direction of the light.
    A lower wall portion of the main body of the actuating device 62 is formed with a long hole 62a extending in the front and rear direction of the light. The output shaft element 64 is arranged to project downward (more particularly just below) from the long hole 62a of the main body of the actuating device 62. In addition, the two lateral left and right surfaces of the main body actuator 62 are formed with tabs 62b having holes at their upper end portions. The range adjustment actuator 60 is fixed to the lower wall part 40a of the support 40 by fixing screws 66 in the respective tabs 62b.
    A front end portion 64a of the output shaft element 64 has a spherical shape whose diameter is larger than a shaft portion of the output shaft element. An end portion of the front end portion 64a has a planar shape. The output shaft element 64 is connected at the level of the front end portion 64a to the pointing nut 52.
    The front end portion 64a of the output shaft element 64 and the pointing nut 52 are connected in a distant position in the right and left direction of a vertical surface comprising an axis Axl s' extending in the front and rear direction of the light and becoming a center of rotation of the aiming screw 46. More specifically, the coupling position D of the front end part 64a of the output shaft element 64 and of the pointing nut 52 is moved inward (to the left) in the vehicle width direction from the screwed-in position C. In addition, the coupling position D is moved to the front side of light in relation to the screwed-in position C.
    The pointing nut 52 is an injection molded product made of resin, and is supported on the light body 12 so that it can slide in the front and rear direction of the light.
    The pointing nut 52 is formed at a part of the coupling position D with a concave part 52a for receiving there the front end part 64a of the output shaft element 64. From more, the pointing nut 52 is formed at a part of the screwed-in position C with a screw engaging part 52b to be screwed-in engaged with the pointing screw 46. The concave part 52a and the screw engaging portion 52b are integrated via a plate-shaped main body portion 52c extending along the horizontal plane.
    The concave part 52a has a cylindrical shape extending in the upper and lower direction, and is connected to the main body part in the form of a plate 52c at a central part of an outer peripheral surface in the upper and lower direction. The concave part 52a has an inner peripheral shape with which the front end part 64a of the output shaft element 64 received in the concave part 52a can be moved relatively in the upper and lower direction and in the direction right and left by predetermined amounts, respectively.
    More specifically, the concave portion 52a has a pair of front and rear vertical surfaces formed in a planar shape having a width in the front and rear direction slightly larger than the diameter of the front end portion 64a of the output shaft member 64, a pair of left and right vertical surfaces formed as part of a cylindrical area larger to some extent than the diameter of the front end portion 64a of the shaft member output 64, and a bottom wall surface formed in a position slightly deeper than a vertical width of the front end portion 64a of the output shaft member 64.
    The output shaft element 64 whose front end part 64a is received in the concave part 52a thus correctly transmits its movement in the front and rear direction of the light to the pointing nut 52, and allows slight play in the upper and lower direction and a relatively large play in the right and left direction.
    Upper end portions of the pair of front and rear vertical surfaces of the concave portion 52a are formed with projections 52al to prevent the front end portion 64a of the output shaft member 64 received in the concave part 52a to separate from the concave part 52a so as to extend over a predetermined length in the right and left direction. In addition, slots 52a2 larger than the projections 52al are formed at portions just below the projections 52a formed at the bottom wall portion of the concave portion 52a.
    At the same time, the screw engaging part 52b is formed in a semi-cylindrical shape extending in the front and rear direction of the light, and is connected at its lower end part to the part of main plate-shaped body 52c.
    A rear end part of the screw engagement part 52b is formed with a funnel-shaped opening 52bl for easy screw engagement with the pointing screw 46.
    As shown in Figures 5 and 6, the plate-shaped main body part 52c has a substantially cross shape extending in the front and rear direction of the light and in the right and left direction, such as seen from above. The concave portion 52a is disposed at a left extension portion 52cl of the plate-shaped main body portion 52c, and the screw engagement portion 52b is disposed at a portion of rearward extension 52c2 thereof.
    The rear extension part 52c2 has a width in the right and left direction greater to a certain extent than the screw engagement part 52b. The pointing nut 52 is supported on the light body 12 so that it can slide in the front and rear direction of the light at the rear extension part 52c2.
    A lower surface of the rear extension part 52c2 is formed with a pair of elastic left and right parts 52e having a substantially semi-cylindrical section and extending in the front and rear direction of the light. The pair of left and right elastic pieces 52e is formed such that inner parts facing each other are spaced from the bottom surface of the backward extending portion 52c2. The pair of left and right elastic pieces 52e is thus elastically deformed by a pressure force in the upper and lower direction. A front end face of each elastic piece 52e extends along the vertical surface. However, a rear end face thereof extends while being inclined relative to the vertical surface towards the front side of the lamp.
    At the same time, the extension part to the left 52cl has a width in the front and rear direction slightly larger than the concave part 52a, and a front end part thereof (this is ie a position farther to the left than the concave part 52a) is formed with a lowered part 52d extending in the horizontal direction in a lower position than the extension part to the left 52cl.
    The lowered part 52d is formed with a rectangular opening 52dl extending in the front and rear direction of the light. In the opening 52dl is arranged a rectangular elastic piece 52f extending in the front and rear direction of the light. The elastic part 52f has a cantilever shape extending slightly downwards from a rear end edge position of the opening 52dl of the lowered part 52d towards the front of the lamp.
    A forward extension portion 52c3 of the plate-shaped main body portion 52c has a width in the right and left direction smaller than the rearward extension portion 52c2, and a portion the front end thereof is formed with a rim portion 52g extending upward along a front end edge of the forward extension portion 52c3.
    Part of a lower surface of the forward extension part 52c3, which is on a side more to the right than the axis Axl of the pointing screw 46, is formed with an elastic part 52h to resiliently press the pointing nut 52 on the light body 12 in the right and left direction.
    The elastic part 52h extends by being folded in a J shape from a rear end position of a vertical wall part extending in the front and rear direction of the light in a position substantially just below the Axl axis towards the front of the fire, and a straight surface of a front end part thereof is formed with a projection in the shape of a semi-circular cylinder 52hl extending in the upper and lower direction.
    A right-extending part 52c4 of the plate-shaped main body part 52c has a width in the front and rear direction smaller than the left-extending part 52cl, and a part of front end thereof (that is to say a position more to the right than the axis Axl) is formed with a stop 52i to prevent the pointing nut 52 from rotating around the coupling position D d ' a predetermined angle or more.
    As shown in Figure 3, the support 40 is formed with a nut engagement piece 40b extending downward from a right end portion of the bottom wall portion 40a thereof. this. The nut engaging piece 40b has an L-shaped section extending in the front and rear direction of the light over a predetermined length. The nut engaging piece 40b extends downward from the bottom wall portion 40a and is then bent to the right at a right angle at the front end portion.
    The stop 52i is formed to surround the front end part of the nut engaging part 40b from the lower, right and upper sides. The stop 52i is formed to have a length in the front and rear direction shorter than the nut engaging piece 40b with a predetermined interval from the front end portion of the nut engaging piece 40b .
    As shown with the dashed line and the dotted line in Figure 6, when the pointing nut 52 is rotated in the right and left direction from an initial position (that is to say say a position in which a central axis of the screw engaging part 52b coincides with the axis Axl) around the coupling position D by a predetermined angle, a front end edge or a rear end edge of a side wall of the stop 52i is brought into contact with the front end part of the nut engaging part 40b, so that the additional rotation of the latter is limited.
    Likewise, when the pointing nut 52 is rotated in the upper and lower direction from the initial position around the coupling position D by a predetermined angle, an upper surface wall or a surface wall lower of the stop 52i is brought into contact with the front end part of the nut engaging part 40b, so that the additional rotation thereof is limited.
    As shown in Figure 4, a part, which is close to a rear surface wall 12b, a lower surface wall 12a of the fire body 12 is formed as a raised part 12al higher than the other general part.
    An upper surface of the raised part 12al is formed with a pair of left and right sliding engagement parts 12c intended to support the pointing nut 52 so as to be able to slide in the front and rear direction of the light so as to extend parallel to each other from the rear surface wall 12b towards the front of the lamp.
    In addition, the general part of the lower surface wall 12a of the fire body 12 is formed with a pair of beads 12d extending linearly towards the fire front. The pair of beads 12d is formed in a position slightly more sliding engagement 12c position distant from the substantially the same size on the left positioned as the part on the right and a corresponding position of that the overall width of the elastic piece 52h in the direction right and left.
    As shown in Figure 7, the pointing nut 52 is mounted on the light body 12 from the front light side to a direction shown with the arrow in Figure 7 in a state where the part d the front end 64a of the output shaft element 64 is mounted in the concave part 52a.
    That is, once the backward extending portion 52c2 of the plate-shaped main body portion 52c of the pointing nut 52 is inserted between the pair of portions sliding engagement 12c left and right, the screw engagement part 52b of the pointing nut 52 is inserted into the front end part of the pointing screw 46 to screw in the pointing screw 46 and is moved to the rear light side, so that the pointing nut is mounted on the light body 12.
    At this time, when the flange portion 52d3 of the pointing nut 52 is pushed from the front side of the lamp by a finger, the pointing nut 52 can be easily moved to the rear side of the lamp along the upper surface of the lower surface wall 12a of the light body 12. In addition, at this time, the pair of left and right elastic pieces 52f is brought into contact with the raised part 12al of the wall of bottom surface 12a and is thus resiliently deformed, so that the rearward extension portion 52c2 can be easily engaged in the pair of left and right sliding engagement portions.12c. In addition, at this time, the elastic parts 52f are brought into contact with the general part of the lower surface wall 12a and are thus elastically deformed and the elastic part 52h is inserted between the pair of beads 12d to deform in a manner elastic the front end portion 52hl and to cause the same contact with the right bead 12d, so that a position of the pointing nut 52 is maintained stably.
    Similarly, the pointing nut 52 is configured so that it can be rotated from the initial position around the coupling position D before it is mounted on the light body 12. However , the stop 52i is brought into contact with the nut engaging part 40b of the support 40, so that the rotation of the pointing nut 52 is prevented from rotating by a predetermined angle or more. In addition, since the rear end portion of the screw engagement portion 52b is formed with the funnel-shaped opening 52bl, engagement in a screwed manner with the pointing screw 46 can be easily accomplished during mounting on the fire body 12.
    Figure 8 is a view similar to Figure 2 for illustrating a vehicle light range control function 10 of the illustrative embodiment.
    Figure 8 shows an aspect where the fire unit 20A is subjected to a range adjustment with the support 40 in both upper and lower directions from a reference pointing position in the upper and lower direction by driving the range adjustment actuator 60.
    As shown with the solid line in Figure 8, in a state where the light unit 20A is in the reference pointing position in the upper and lower direction and is not subject to the adjustment of carried, the optical axis Ax extends horizontally in the front and rear direction of the light.
    As shown with the broken line in Figure 8, during an upward range adjustment of the light unit 20A, the output shaft element 64 of the adjustment actuating device of range 60 moves relative to the main body of actuating device 62 towards the rear light side. At this time, since the front end portion 64a of the output shaft member 64 is connected to the pointing nut 52, which is in the reference pointing position in the upper and lower direction, in the coupling position D, the main body of the actuating device 62 is actually moved towards the front fire side. The light unit 20A is thus turned upwards around the central axis of rotation Lab, with the support 40, and the optical axis Ax extends obliquely upwards.
    On the other hand, as shown with the dotted line in Figure 8, during a downward range adjustment of the fire unit 20A, the output shaft element 64 of the range adjuster actuator 60 moves relative to the main actuator body 62 toward the fire front side. However, actually, the main actuator body 62 moves to the rear light side.
    The light unit 20A is thus turned down around the central axis of rotation Lab, with the support 40, and the optical axis Ax extends obliquely downwards.
    The operational effects of the illustrative embodiment are described next.
    The vehicle light 10 of the illustrative embodiment includes the range adjustment actuator 60 for rotating the light unit 20A in the upper and lower directions, independently of rotation by pointing . Since the output shaft member 64 of the range adjuster actuator 60 is connected at the front end portion 64a to the pointing nut 52 which is screw-engaged with the pointing screw 46 for pointing the light unit 20A in the upper and lower direction, it is possible to achieve the range adjustment by moving the output shaft element 64 relative to the main body of the actuating device 62 in the front and rear direction of the light.
    At this time, the output shaft element 64 of the range adjustment actuator 60 is arranged to protrude downward from the main body of the actuator 62 fixed and supported on the light unit 20A and is not arranged in series with the pointing screw 46, unlike the prior art. Therefore, it is possible to reduce an added length of the reach adjustment actuator 60 in front and of the pointing screw 46 in rear, so that the direction of ensuring is possible to have range adjustment actuation 60.
    the illustrative embodiment, easily a space for device there According to the front end portion 64a of the output shaft element and the pointing nut 52 are connected in the remote position in the right and left direction of the vertical surface comprising the axis Axl during the rotation of the aiming screw 46, and the following operational effects can be achieved.
    That is, since the coupling position D of the output shaft element 64 and the pointing nut 52 is offset in the right and left direction relative to the engaged position in a screwed manner C of the pointing screw 46 and the pointing nut 52, it is possible to increase a degree of freedom of arrangement of the actuator for adjusting the range 60. It is thus possible to ensure easily a space for disposing of the range adjustment actuating device 60, in correspondence with the light configuration.
    Consequently, as shown in FIG. 5, since an element on the vehicle body side 2 (for example a pipe for a windshield washer tank and the like) is disposed in the vicinity of the rear of the fire body 12, even when it is necessary to have the pointing screw 46 avoiding the element on the vehicle body side, it is possible to couple the output shaft element 64 and the pointing nut 52 in a state where the range adjustment actuator 60 is easily arranged.
    Thus, according to the illustrative embodiment, it is possible to easily provide the space for disposing therein the actuation device for adjusting the range 60 in the vehicle light 10 comprising the actuation device for range adjustment 60, in correspondence with the fire configuration.
    In addition, according to the illustrative embodiment, the coupling position D of the output shaft element 64 and the pointing nut 52 is offset in the right and left direction relative to the screwed in position C of the pointing screw 46 and the pointing nut 52, so that it is possible to easily reduce a width added with the actuator for adjusting the range 60 and the nut pointing 52 in the upper and lower direction.
    Similarly, in the illustrative embodiment, the pointing nut 52 is supported on the light body 12 so that it can slide in the front and rear direction of the light. Therefore, it is possible to prevent in advance a situation in which, when the pointing screw 46 is turned so as to point the fire unit 20A in the upper and lower direction, the pointing nut 52 attempts also to rotate and an excessive force is thus applied to the part coupled with the output shaft element 64 of the range adjustment actuator 60.
    At this time, the pointing nut 52 is provided with elastic parts 52e, 52f for resiliently pressing the pointing nut 52 on the lamp body 12 in the upper and lower direction on the two left sides and straight from the coupling position D with the output shaft element 64. Thus, even if the coupling position D of the output shaft element 64 and the pointing nut 52 is offset in the right and left direction with respect to the screwed in position C of the pointing screw 46 and the pointing nut 52, once the state of engagement between the pointing nut 52 and the light body 12 is held securely, the pointing nut 52 can be made to slide relative to the light body 12.
    In addition, in the illustrative embodiment, the pointing nut 52 is provided with the elastic part 52h for resiliently pressing the pointing nut 52 on the fire body 12 in the right direction and left at a part positioned on a side opposite the coupling position D with the output shaft element 64 relative to the vertical surface comprising the axis Axl. The following operational effects can thus be obtained.
    That is to say, when the coupling position D of the output shaft element 64 and the pointing nut 52 is offset in the right and left direction relative to the engaged position screwed C of the pointing screw 46 and the pointing nut 52, an external force of displacement of the pointing nut 52 in the right and left direction is applied due to the range adjustment and the pointing. However, since the pointing nut 52 is resiliently pushed in the right and left direction by the elastic piece 52h, the displacement of the pointing nut 52 can be retained. Thus, once the state of engagement between the pointing nut 52 and the light body 12 is securely maintained, the range adjustment and pointing can be achieved.
    In addition, in the illustrative embodiment, the pointing nut 52 is provided with the stop 52i to prevent the pointing nut 52 from rotating around the coupling position D by a predetermined angle or plus via contact with support 40 configured to support the fire unit 12A, at a portion positioned on a side opposite the coupling position D with the output shaft member 64 relative to the vertical surface comprising the axis Asl. The following operational effects can thus be obtained in a fire manufacturing process.
    That is to say, when mounting the support 40 on the light body 12 after mounting the range adjustment actuator 60 on the support 40 and coupling the pointing nut 52 on the output shaft element 64 of the range adjustment actuator, it is possible to allow a posture of the pointing nut 52 to enter a predetermined angle of inclination range by virtue of the the operation for limiting the rotation of the stop 52i for the pointing nut 52. Consequently, it is possible to easily engage the pointing nut 52 with the pointing screw 46 supported on the light body 12 .
    In addition, in the illustrative embodiment, the pointing nut 52 is formed with the concave part 52a to receive there the front end part 64a of the output shaft element 64 of the device. range adjustment actuator 60. The concave portion 52a has the shape of an inner peripheral surface with which the front end portion 64a of the output shaft member 64 received in the concave portion 52a can be moved relative in the upper and lower direction of the predetermined amount. Therefore, after preventing excessive force from being applied to the coupled portion of the output shaft member 64 of the range adjuster actuator 60 and the pointing nut 52, the movement of the The output shaft element 64 in the front and rear direction of the light can be transmitted as the rotation of the light unit 20A in the upper and lower direction. It is thus possible to carry out smoothly the adjustment of the range and the pointing in the upper and lower direction and to absorb an assembly error of each element.
    Likewise, the concave part 52a of the pointing nut 52 has the shape of an inner peripheral surface with which the front end part 64a of the output shaft element 64 received in the concave part 52a can be moved relatively in the right and left direction by the predetermined amount. Therefore, even when the central axis of rotation Lab of the light unit 20A when adjusting the range and pointing in the upper and lower direction extends in a direction inclined with respect to the vehicle width direction in forward and reverse direction, it is possible to prevent excessive force from being applied to the coupled portion of the output shaft member 64 of the range adjuster actuator 60 and the pointing nut 52 and absorb the mounting error of each element.
    In the illustrative embodiment, the coupling position D of the front end part 64a of the output shaft element 64 and the pointing nut 52 is established in the position distant towards inside (to the left) in the vehicle width direction of the vertical surface comprising the Axl axis. However, a configuration where the coupling position is established in a distant position outward (to the right) in the vehicle width direction can also be adopted.
    In the illustrative embodiment, the elastic parts 52e, 52f are formed integrally with the pointing nut 52. However, a configuration where a metallic elastic element is mounted on the pointing nut 52, in the form of a separate element, can also be adopted, for example.
    In the illustrative embodiment, the two fire units 20A, 20B are all fire units of the projector type. However, a parabolic type fire unit can also be adopted.
    In the illustrative embodiment, the two fire units 20A, 20B are supported on the fire body 12 via the support 40. However, one or three or more fire units can be supported on the fire body 12 via the support 40. In addition, the fire unit can be directly supported on the fire body 12 without passing through the support 40.
    Modified embodiments of the illustrative embodiment are described below.
    A first modified embodiment of the illustrative embodiment is first described.
    Figure 9 is a bottom view showing main parts of a pointing nut 152 according to the first modified embodiment.
    As shown in Figure 9, the basic configuration of the pointing nut 152 is similar to the illustrative embodiment. However, a configuration of a forward extending portion 152c3 of a plate-shaped main body portion 152c is different from the illustrative embodiment.
    That is, in the case of the pointing nut 52 of the illustrative embodiment, the lower surface of the forward extending portion 52c3 of the body portion main plate-shaped 52c is formed with the elastic piece 52h. However, in the case of the pointing nut 152 of the first modified embodiment, a lower surface of the forward extension portion 152c3 of the plate-shaped main body portion 152c is formed with a portion of elastic part support 152j, and a metallic elastic part
    160 is mounted on the elastic part support part 152j.
    The elastic part 160 is formed by forming a leaf spring in a substantially C shape in a horizontal plane. The elastic part 160 has a base end part 160b engaged and fixed on an engaging part 152jl of elastic 152j and protrudes towards the elastic 152j.

    first form is possible similar to the it of modified embodiment also, operational illustration.
    obtaining the embodiment effects [0099] In addition, modified embodiment, by adopting the configuration of the first it is possible to sufficiently ensure the elastic repulsive force of the elastic part 160.
    A second modified embodiment of the illustrative embodiment is then described.
    Figure 10 is a view similar to Figure 2 showing a vehicle light 210 of the second modified embodiment.
    As shown in Figure 10, the basic configuration of the vehicle light 210 is similar to the illustrative embodiment. However, in the second modified embodiment, a mechanism for pointing and adjusting the range of the fire unit 20A with a support 240 is arranged being vertically inverted with respect to the illustrative embodiment, and a configuration of a fire body 212 is also different from the illustrative embodiment.
    That is, in the second modified embodiment, the support 240 configured to support the fire unit 20A has a vertically inverted shape with respect to the support 40 of the illustrative embodiment , and when pointing the light unit 20A in the upper and lower direction, the central axis of rotation Lab is located below the light unit 20A.
    In the second modified embodiment also, when pointing the fire unit 20A in the right and left direction, the central axis of rotation Lac is a line extending vertically. However, a positional relationship between the engagement position A and the coupling position D is the opposite of the illustrative embodiment.
    With this, in the second modified embodiment, the pivot 42 and the spherical bearing 48 are located below the light unit 20A, and the pointing screw 46, the pointing nut 50 and the device range adjustment actuator 60 are located above the light unit 20A.
    In the second modified embodiment, the output shaft element 64 of the range adjustment actuator 60 is connected to the pointing nut 52 while being arranged to project upwards (more especially just above) the main body of actuating device 62.
    In the second modified embodiment, a part, which is close to a rear surface wall 212b, of an upper surface wall 212e of the fire body 212 is formed as a lowered part 212el, a lower surface 212al lowered part is formed with a pair of left and right sliding engagement parts
    212c, and a general part of the upper surface wall 212e of the fire body 212 is formed with a pair of beads 212d.
    In the third modified embodiment also, the output shaft element 64 of the range adjustment actuator 60 is arranged to protrude upwards from the main body of the actuator 62 fixed and supported on the light unit 20A and is not to be arranged in series with the pointing screw 46, unlike the prior art. Therefore, it is possible to reduce an added length of the range adjustment actuator 60 and the pointing screw 46 in the front and rear direction, so that it is possible to easily ensure the space to have there adjustment of range 60. In the second, the actuation device of modified embodiment also, since the coupling position D of the output shaft element 64 and the pointing nut 52 is offset in the right and left direction relative to the screwed in position C of the pointing screw 46 and the pointing nut 52, it is possible to increase the degree of freedom of arrangement of the device range adjustment actuation 60. It is thus possible to easily provide the space for disposing of the range adjustment actuation device 60 there, in correspondence with the fire configuration.
    A third modified embodiment of the illustrative embodiment is then described.
    Figure 11 is a view similar to Figure 2 showing a vehicle light 310 of the third modified embodiment.
    As shown in Figure 10, the basic configuration of the vehicle light 310 is similar to the second modified embodiment. However, a configuration of a pointing screw 346 is different from the second modified embodiment, and a configuration of a light body 312 is correspondingly also different from the second modified embodiment.
    That is, the aiming screw 346 of the third modified embodiment has a configuration in which a main body part of the screw 34 6A extending in the front and rear direction of the light and a drive shaft portion 346B extending in the upper and lower directions are coupled via a pair of bevel gears 346Aa, 346Ba.
    The main body part of the screw 346A is disposed on the axis Axl extending in the front and rear direction of the light, like the pointing screw 46 of the second modified embodiment. The main screw body part 346A has a shape in which a rear part of the pointing screw 46 of the second modified embodiment is cut, and the bevel gear 346Aa is fixed on a rear end part of the part of main screw body.
    In the case of the fire body 312 of the third modified embodiment also, a part, which is close to a rear surface wall 312b, of an upper surface wall 312e is formed as a lowered part 312el , a lower surface of the lowered portion 312al is formed with a pair of left and right sliding engagement portions 312c, and a general portion of the upper surface wall 312e of the fire body 312 is formed with a bead 312d.
    The lowered portion 312el of the upper surface wall 312e is provided with a support 318 configured to rotatably support the main body portion of the screw 34 6A in the vicinity of the front of the bevel gear 346Aa.
    On the other hand, the drive shaft part 346B is arranged on an axis Ax2 extending perpendicular to the axis Axl, and is rotatably supported at an upper end part of this on the upper surface wall 312d of the lamp body 312. The bevel gear 346Ba is in engagement with the bevel gear 346Aa of the main body part of the screw 346A by being fixed on a lower end part of the part 346Bh drive shaft.
    In the third modified embodiment, when the drive shaft part 346B of the pointing screw 346 is caused to rotate about the axis Ax2, the main body part of the screw 34 6A is driven in rotation around the axis Axl, so that the light unit 20A is pointed in the upper and lower direction.
    In order to implement the arrangement of the pointing screw 346, the light body 312 of the third modified embodiment has a configuration in which an upper part of the rear surface wall 312b is formed as a projection rear 312bl which projects towards the rear side of the lamp in relation to the other general part.
    In the third modified embodiment also, it is possible to obtain the operational effects similar to the second modified embodiment.
    Similarly, when the configuration of the third modified embodiment is adopted, it is possible to easily point the light unit 20A in the upper and lower direction by actuation from above the vehicle light 310.
    [0122] At the same time, the numerical values described in the illustrative embodiment and the modified embodiments thereof are merely by way of example, and can be appropriately set to different values.
    In addition, the present invention is not limited to the configurations described in the illustrative embodiment and the modified embodiments and can adopt differently modified configurations.
    In the present invention, the range adjustment actuating device and the pointing nut are perfectly designed as described above.
    The pointing screw can be configured only by a part extending in the front and rear direction of the light since it is supported on the light body so that it can be turned around the axis extending in the front and rear direction of the light, or may have a configuration where a part extending in a direction which intersects the front and rear direction of the light is connected to the part extending in the front and rear direction of the light by the intermediate of a pinion or equivalent.
    The output shaft element is arranged to protrude upwards or downwards from the main body of the actuating device. However, the output shaft element does not necessarily need to protrude just up or down. For example, the output shaft member may be arranged to protrude in a direction inclined with respect to a direction just above or just below as long as it is within a range in which the range adjustment and the pointing in the upper and lower direction and the right and left direction should not be hindered.
    The output shaft element is connected to the pointing nut at its front end part. However, the specific coupling structure is not particularly limited.
    The coupling position of the front end part of the output shaft element and the pointing nut is not particularly limited as long as it is distant in the right and left direction of a vertical surface comprising the axis.
    The vehicle light of the present invention includes the range adjustment actuator for rotating the light unit in the upper and lower direction, regardless of rotation by pointing. However, since the output shaft element of the range adjustment actuator is connected at its front end portion to the pointing nut which is screwed in with the pointing screw for the pointing the light unit in the upper and lower direction, the range adjustment can be achieved by moving the output shaft member relative to the main actuator body in the front and rear direction of the light.
    At this time, the output shaft element of the range adjustment actuating device is arranged to protrude up or down from the main body of the actuating device fixed and supported on the 'fire unit and is not arranged in series with the pointing screw, unlike the prior art. Therefore, it is possible to reduce an added length of the range adjustment actuator and the pointing screw in the front and rear direction, so that it is possible to easily provide a space for it. the range adjustment actuator.
    In addition, according to the present invention, the front end part of the output shaft element and the pointing nut are connected in the distant position in the right and left direction of the vertical surface comprising l axis during rotation of the aiming screw, and the following operational effects can be obtained.
    That is, since the coupling position of the output shaft element and the pointing nut is offset in the right and left direction relative to the position engaged in a screwed manner of the pointing screw and the pointing nut, it is possible to increase a degree of freedom of arrangement of the actuator for adjusting the range. It is thus possible to easily ensure the space for disposing of the actuation device for adjusting the range, in correspondence with the configuration of the light.
    Similarly, according to the present invention, it is possible to easily ensure the space for disposing therein the actuation device for adjusting the range in the vehicle light comprising the actuating device for adjusting the range, in correspondence with the fire configuration.
    In addition, according to the present invention, the coupling position of the output shaft element and the pointing nut is offset in the right and left direction relative to the screwed in position of the pointing screw and pointing nut, so that an added width of the reach adjuster and pointing nut can be easily reduced in the upper and lower direction.
    In the above configuration, the pointing nut can be supported on the light body so that it can slide in the front and rear direction of the vehicle light. It is thus possible to avoid in advance a situation in which, when the aiming screw is turned so as to point the light unit in the upper and lower direction, the aiming nut also attempts to turn and a excessive force is thus applied to a part coupled with the output shaft element of the range adjustment actuator.
    At this time, the pointing nut can be provided with elastic parts to resiliently press the pointing nut on the lamp body in the upper and lower direction on both the left and right sides of the position. coupling with the output shaft element. Thus, even if the coupling position of the output shaft element and the pointing nut is shifted in the right and left direction relative to the screwed in position of the pointing screw and the pointing nut, once the state of engagement between the pointing nut and the light body is securely maintained, the pointing nut can be made to slide relative to the light body.
    In the above configuration, the pointing nut can be provided with an elastic piece for resiliently pressing the pointing nut on the lamp body in the right and left direction at a part positioned on a side opposite to the position of coupling with the output shaft element with respect to the vertical surface comprising the axis. The following operational effects can thus be obtained.
    That is to say, when the coupling position of the output shaft element and the pointing nut is shifted in the right and left direction relative to the position engaged in a screwed manner of the aiming screw and the aiming nut, an external force for moving the aiming nut in the right and left direction is applied due to the range adjustment and aiming. However, since the pointing nut is resiliently pressed in the right and left direction by the elastic piece, the displacement of the pointing nut can be retained. Thus, once the state of engagement between the pointing nut and the light the body is securely maintained, the range and pointing adjustment can be achieved.
    Each of the elastic pieces can be formed integrally with the pointing nut or can be mounted on the pointing nut, as a separate element.
    In the above configuration, the pointing nut may be provided with a stopper to prevent the pointing nut from rotating around the coupling position by a predetermined angle or more by means of contact with the fire unit, at a part positioned on a side opposite to the position of coupling with the output shaft element with respect to the vertical surface comprising the axis. The following operational effects can thus be achieved in a fire manufacturing process.
    That is to say that, during the mounting of the fire unit on the light body after mounting of the range adjustment actuating device on the fire unit and coupling of the nut. pointing with the output shaft element of the range adjustment actuator, it is possible to allow a posture of the pointing nut to enter a predetermined angle of inclination range by an operation limit rotation of the stopper for the pointing nut. Therefore, it is possible to easily screw in the pointing nut with the pointing screw supported on the light body.
    The stop can be formed integrally with the pointing nut or can be mounted on the pointing nut, as a separate element.
    The range adjustment actuator of the present invention has the configuration where the output shaft element protrudes up or down from the main body of the actuator and is connected at the level of the front end part to the pointing nut. Therefore, the pointing nut can be formed with a concave portion to receive the front end portion of the output shaft member therein, and the concave portion can be configured to have an interior peripheral surface shape with wherein the front end portion of the output shaft member received in the concave portion can be moved relatively in the upper and lower directions by a predetermined amount.
    By adopting the above configuration, after having prevented excessive force from being applied to the coupled part of the output shaft element of the range adjustment actuator and of the pointing nut , the movement of the output shaft element in the front and rear direction of the light can be transmitted as a rotation of the light unit in the upper and lower direction, so that the adjustment of range and pointing in the upper and lower direction can be done smoothly. In addition, by adopting the above configuration, it is possible to absorb an assembly error of each element.
    [0145] At this time, the shape of the inner peripheral surface of the concave part of the pointing nut can be formed in a shape with which the front end part of the output shaft element received in the concave part can be moved relatively in the right and left direction by a predetermined amount. Thus, even when the central axis of rotation of the light unit when adjusting range or pointing in the upper and lower direction extends in an inclined direction relative to a vehicle width direction in the forward direction and rear, it is possible to easily prevent excessive force from being applied to the coupled portion of the output shaft member of the range adjustment actuator and the pointing nut. In addition, by adopting the above configuration, it is possible to absorb the mounting error of each element.
