The upper end opening is closed by the upper surface of the base stand 8 which supports the motor 3 or the drive transmission means and is accommodated in the main body casing 1, and a plug for power supply is provided at the lower end of the main body casing 1. (9) is provided. In addition, the main body casing 1 may have a built-in battery.
    [48] The base stand 8 provided with the hook connection part 10 in an upper surface part consists of the base stand 12 for motor built-in, and the cover 13 fixed by the screw 131n in the side opening part of this, The motor 3 is fitted from the lower side of the motor built-in part 12a below the base built-in base 12 for motor built-in. Then, the overload clutch 18 and the gear 19 are accommodated in the upper inner space 16 of the base for motor built-in base 12 whose side opening is covered by the cover 13, and the half casing 7 ( The support frame 25 of the base for motor built-in base 12 is sandwiched between the projections 7d and 7e in 7), so that it is arranged inside the main body casing 1.
    [49] As shown in FIG. 13, the overload clutch 18 provided by the shaft 18j in the base 8 consists of the front gear 181, the small gear 180, and the clutch spring 182. As shown in FIG. As the small gear 180 has a fitting portion 180a and a flange portion 180b at one end thereof, the small gear 180 has a positioning protrusion 180c and a screwing hole 180d at the end surface of the fitting portion 180a. Equipped. The front gear 181 is provided with a hole 181a in which the fitting portion 180a of the small gear 180 is freely rotated, and has a groove-shaped locking portion 181b around the hole 181a.

    [51] The fitting portion 180a of the small gear 180 can be freely rotated into the hole 181a of the front gear 181 while the flange portion 180b is fixed to the outer surface of the front gear 181 from the outside of the hole 181a. In this state, the positioning hole 182c of the leaf spring 182 is inserted into the positioning projection 180c at the end face of the fitting portion 180a to determine the position, and the screw is inserted from the screw insertion hole 182d. By inserting 183 and screwing into the screwing hole 180d of the small gear 180, the clutch spring 182 is installed in the small gear 180, and the engaging projection 182b of the clutch spring 182 is mounted. When elastically caught by the locking portion 181b, the rotation transmitted to the front gear 181 is transmitted to the small gear 180 through the clutch spring 182. Then, when the power of a predetermined torque or more is transmitted, the engaging projection 182b installed on the clutch spring 182 is pulled out of the engaging portion 181b so that the front gear 181 idles with respect to the small gear 180. For this reason, when the gears are caught with hair or foreign objects are stopped, the torque of the motor 3 can be cut off in the middle, thereby preventing damage to the drive transmission portion.

The stopper protrusion 26b protrudes upward from the upper side of the inner one, and the slide is freely inserted in the tunnel passage of the tunnel protrusion 10a, and the stopper protrusion 26b is a hole 15b. The slide is freely engaged in the inside, and is mounted to the tunnel protrusion 10a. A spring 26d is inserted in the tunnel passage between the pair of slide frames 26 and 26 which the stopper projection 26b is prevented from coming off by contacting the edge of the hole 15b, and the spring 26d. Both sides of the slide frame (26, 26) is applied to the outside and the elastic force is applied. And the operation part 26a of both slide frames 26 protrudes outward of the main body casing 1 through the hole 7f formed in the main body casing 1.
    [55] Next, the hair loss head 2 which consists of the base stand block 15 and the hair loss block 24 is demonstrated, The hair loss block 24 rotates with hair removal means, as shown to FIG. 10 and FIG. Cylinder 4, cylinder base 27 and cylinder cover 28 supporting the rotary cylinder 4, cam 29, retaining spring 30, head frame 31, and FIG. It consists of the base 300 shown to.
    [56] The cylinder base 28 and the cylinder cover 28 provided at one end of the cylinder are rotated by a shaft hole 28b provided in the protruding support portions 27a and 28a protruding upward from each other. Supporting both ends of the shaft (4b) inserted into the (4), the rotation cylinder 4 is freely maintained around the shaft, and each of the projection support (27a) 28a is each ( (Iii) Cam insertion holes 27c and 28c having a hole shape, and shaft support grooves 27d and 28d positioned at upper and lower edge portions of the cam insertion holes 27c and 28c. Then, the roller-shaped cams 29 are respectively inserted into the cam insertion holes 27c and 28c, and the upper and lower ends of the roller shafts 29a inserted into the cams 29 are axially supported grooves 27d and 28d, respectively. ), The horizontal rotation of the cam 29 is supported freely. A part of the cam 29 protrudes inward from the cam insertion holes 27c and 28c.
    [57] In addition, a retaining spring 30 is provided outside the protruding support portions 27a and 28a. The retaining spring 30 is fixed to the cylinder attachment base 27 and the cylinder cover 28 by a screw 301 inserted through the hole 30a of the foundation, and has a hole 30b thereon. The upper and lower ends of the roller shaft 29a are elastically pressed at the upper and lower edge portions of the hole portion 30b. The hole 30b corresponds to the cam 29 so that the cam 29 does not come into contact with the holding spring 30.
    [58] On the outer surface of both ends of the cylinder base 27 and the cylinder cover 28 fixed to the upper surface of the base 300 with the screw 301, a button 281 applied to the outside by the spring 280 is provided. It is installed. The button 281 includes a hook 281a for attaching and detaching the frame 31. When the button 281 is pressed, the button 281a is pulled out of the hook engaging portion 31a of the frame 31. 31) can be removed.
    [59] Moreover, the recessed part 27i is formed in the cylinder cover 28 side of the base stand 27 with a cylinder, and the drive gear 40 is arrange | positioned here. The drive gear 40 whose both ends are supported by the base with a cylinder 27 and the shaft 40j axially supported by the cylinder cover 28 fits with the gear 41g of the rotary cylinder 4. At the same time, the gear meshes with the gear 15c of the base block 15.
    [60] As shown in Figs. 9 and 12, the base block block 15 includes a base body 15a embedded in the base block cover 155 and a base frame surrounding the outer periphery of the base body 15a. A gear 155 and a gear 15c and a gear 15e disposed in the recess 15h opened above the base body 15a and supported by the shaft 15f in the vertical direction. 15e meshes with the front gear portion provided by the gear 15c supported by the horizontal shaft 105j, and integrally includes an eccentric cam 15g.
    [61] The depilation block 24 is provided on the base block 2, and is provided on the lower surface of the base 300 of the depilation block, and the hole 27Ab provided by the rib 27A located in the recess 15h is provided. The slide guide shaft 15j penetrating the base body 15a is inserted into the base 300, that is, the hair loss block 24 is freely mounted in the axial direction of the slide guide shaft 15j.
    [62] In addition, springs 15k and 15k are respectively sandwiched between the spring base 27Aa formed in each rib 27A and the inner surface of both ends of the recessed portion 15h, so that the hair loss block 24 is formed of a base block ( Reciprocating movement in the axial direction of the rotation cylinder 4 with respect to 15 is free, and the hair loss block 24 is located in the center of the base block 15 by the spring force by both springs 15k. have.
    [63] Moreover, although the recessed part 27B is formed in the center of the lower surface of the base 300, the eccentric cam 15g is caught by this recessed part 27B. When the eccentric cam 15g rotates eccentrically, the eccentric cam 15g presses the inner surface of the recess 27B to reciprocate the base block 15 against the spring force of the spring 15k. The width of the concave portion 27B in the direction orthogonal to the rotation axis of the rotation cylinder 4 is not less than twice the amount of the eccentricity of the eccentric cam 15g so as not to move in the direction orthogonal to the rotation axis.
    [64] Here, both springs 15k and 15k, which apply a force to the hair loss block 24 that reciprocates periodically by the rotation of the eccentric cam 15g, absorb the inertial force at the end point of the reciprocating motion and prevent the collision to make a collision sound. Reduce the noise of the back.
    [65] Thus, the hair loss head 2 to which the hair loss block 24 reciprocates freely in the axial direction of the rotation cylinder 4 with respect to the base block 15 is the base body of the base block 15. It is attached to the main body casing 1 by connecting the hooks 11 and 11 provided in the lower surface to the hook connection part 10 of the main body casing 1. This attachment inserts the pair of hooks 11 of the lower surface of the hair loss head 2 in the opening which made the rectangular shape of both slide frames 26, respectively, while pressing the operation part 26a, and in this state the operation part 26a This is achieved by releasing the pressure of the spring 26d so that both slide frames 26 are moved outward and the support hook 261b is caught by the hook 11. Thus, the hair loss head 2 ), The small gear portion of the gear 19 having the large gear portion and the small gear portion is engaged with the gear 15c in the state where the main body casing 1 is provided. When removing the hair loss head 2, since the support hook 261b can be pulled out from the hook 11 by pressing the operation part 26a, the hair loss head 2 may be removed in this state.
    [66] Next, the rotation cylinder 4 in the hair removal block 24 will be described. As shown in Figs. 15 and 16, the rotation cylinder 4 has a pair of substantially cylindrical members 41a and 41b. Formed in the axial direction, the outer peripheral surface of which has a plurality of concave portions 4a (arranged at intervals of 45 ° in the illustrated example, eight places) in the circumferential direction, and in each concave portion 4a The main body unit 32 is fitted.
    [67] As shown in FIG. 17, the main unit for hair loss 32 here has a branch plate 33, a plurality (4 pieces in the illustrated example) of movable nail parts 5a and 6a, and , Which consists of point stop members 34 and 35 and fixed nail parts 36 and 37, the fixed nail parts 36 and 37 formed integrally in a pair of two pieces, respectively. It is supposed to be.
    [68] The spot plate 33 is provided with angle holes 33a and 33b for fitting the point stop members 34 and 35 and each hole 33c for fitting movable nail parts. The projections 34a and 35a provided on the bottom surface of the stop members 34 and 35 are each angled to the branch plate 33 through the holes 36a and 37a formed in the fixed nail portions 36 and 37. Fixing the fixed nail portions 36 and 37 is also performed by press-fitting the holes 33a and 33b. Assembling is simplified by using two sets of the fixed nail parts 36 and 37. In particular, when plural hair removal unit 32 is arranged in the circumferential direction of the rotation cylinder 4, the length is perpendicular to the rotation axis. Since it can be made small, the outer diameter of the rotating cylinder 4 can also be made small.
    [69] The movable nail portions 5a and 6a are fixed to the nail portion 36 by hooking the ribs 34c and 35c provided at both ends of the stop members 34 and 35 with the projections 5b and 6b at both ends. It is attached to the flank of (37). At this time, with respect to the fixed nail part 36 and 37 in which two pieces were formed integrally, the movable nail parts 5a and 6a use independent one by one, and the two fixed nail parts which are integrated ( As for the 36 and 37, the one movable nail part 5a and 6a are made into the holes 36a of the fixed nail part 36 and 37 so that the movable nail part 5a and 6a are located on the same side. 37a) located inside.
    [70] As described above, the hair loss main unit 32 assembled as one unit is fitted into each recess 4a of the rotation cylinder 4, and at the same time, a hole 4b formed at one end of the recess 4a. ), The shaft 41 is inserted into the holes 34d and 35d of the point stop members 34 and 35 and the holes 5a1 and 6a1 of the four movable nail portions 5a and 6a, respectively. It passes through, and is attached to the recessed part 4a by inserting the front-end | tip part of the said shaft 41 into the hole 4b1 of the rotating cylinder 41b of the other end.
    [71] Further, in the axial end surface of one rotary cylinder 41a in the rotary cylinder 4, as shown in Fig. 15, a plurality of holes 4c are formed in the circumferential direction, and the opening / closing lever 38a is formed thereon. (38b) 38c (38d) and the open / close levers 39a (39b) 39c (39d) are alternately inserted in the circumferential direction. Moreover, the press part 381a, 381b, 381c, 381d of the edge part of opening-closing lever 38a, 38b, 38c, 38d, and the opening-closing lever 39a, 39b, 39c ( 39d) Pressing portions 391a, 391b, 391c and 391d at the ends are located on the inner circumferential side of the rotary cylinder 4, and both ends are pressed portions 391a, 391b and 391c in the circumferential direction. It overlaps with the end of 391d. In addition, as shown in FIG. 16, in the rotary cylinder 41b at the other end, a plurality of holes 4c are formed in the circumferential direction, and the open / close levers 39a, 39b, 39c, 39d and the open / close lever ( 38a, 38b, 38c and 38d are alternately inserted as described above.
    [72] Then, each opening and closing lever 38a, 38b, 38c, 38d, 39a, 39b, 39c, 39d has a main unit 32 for depilation in each recessed portion 4a of the rotary cylinder 4. ), The grooves 382a, 382b, 382c, 382d, 392a, 392b, 392c, which engage the protruding pieces 5c, 6c of the movable nail portions 5a, 6a. 392d is formed. At this time, the opening / closing lever inserted from the rotation cylinder 41a side is engaged with the protruding piece 6c of the movable nail portion 6a, and the opening / closing lever inserted from the rotation cylinder 41b side is the movable nail portion 5a. Is engaged with the protruding piece 5c.
    [73] In addition, between the end surfaces of the rotary cylinder 4 in the axial direction and the pressing portions of the opening / closing levers 38a, 38b, 38c, 38d, 39a, 39b, 39c, and 39d, the springs were formed by leaf springs. Return spring 370 is disposed. As shown in Figs. 15, 16 and 18, the return spring 370 having a positioning hole in the center thereof engaged with the projection 4d provided in the center of the rotary cylinders 41a and 41b, Four spring pieces 370a having a substantially 'co' shape are integrally provided so that these spring pieces 370a are open / close levers 38a, 38b, 38c, 38d, 39a, 39b and 39c. ) 39d, the force is applied toward the outer side of the rotation cylinder 4 in the axial direction.
    [74] Since the effective length of the spring is increased by making the spring piece 380a substantially 'co' shaped, the spring reaction force when the opening / closing lever is pressed by the cam 29 can be reduced and the rotation is efficient with low load. The spring piece 370a is bent in a spiral shape on the opening / closing lever side from the source to the opening / closing lever side, and the moving amount of the opening / closing lever can be largely caught, and the movable nail part 5a (6a) is possible. The opening amount with respect to the fixed nail parts 36 and 37 can also be enlarged.
    [75] Here, one spring piece 370a pushes two adjacent opening / closing levers 38b and 39d outward, and the other spring piece 370a pushes the opening / closing levers 38c and 39a, so that four spring pieces By the return spring 370 having integrally the 370a, all assembled levers 38a, 38b, 38c, 38d, 39a, 39b, 39c and 39d are forced outward. It is to be added.
    [76] And when the force which presses the opening / closing lever from the outside does not act, the movable nail parts 5a and 6a are angled by the protruding pieces 5c and 6c by pressing outward. It rotates with the hole edge of the hole 33c as a point, and it moves away from the fixed nail part 37 and 36 positioned in the point stop member 34, and presses 381a and 381b of the opening / closing lever. (381c) 381d (391a) 391b (391c) (391d) When an external force is applied from outside, the movable nail portions (5a) (6a) have their protruding pieces (5c) (6c) inward. By being pressed, it rotates by making the hole edge of the angle hole 33c of the point plate 33 into a point, and is pushed to the fixing nail part 36 and 37. Thus, since the return spring 370 which consists of a leaf spring is arrange | positioned at the axial end surface of the rotating cylinder 4, and all the opening / closing levers are forced outward by the return spring 370, assembly is easy, It is possible to obtain an inexpensive rotary cylinder 4.
    [77] Here, the hair loss main unit 32 is a pair of hair loss nail parts for pinching and pulling out hairs by two sets of four fixed nail parts 36 and 37 and four movable nail parts 5a and 6a. Although two or four fixed nail parts 36 and 37 are arranged at equal intervals in the axial direction of the rotation cylinder 4, as apparent from Figs. The position balance at the time is good, and the hair loss efficiency is increased, and since the gripping positions of the hair loss nail portions of the rows of the nail portions provided in the circumferential direction of the rotation cylinder 4 are equally spaced, hairs aimed at easily fall out and hair loss. It can be set as the rotation cylinder 4 with high efficiency.
    [78] In addition, although the structure shown here can move and move the nail | claw parts 5a and 6a of 4 hair loss nail parts in total simultaneously with the fixed nail parts 36 and 37 by moving the opening-closing lever, Simple and good assembly.
    [79] Furthermore, each of the fixed nail parts 36 and 37, which is composed of two pieces, performs the opening and closing operation between the movable nail parts 5a and 6a, which are engaged with the same opening / closing lever, respectively. Since 37 is provided with the elastic parts 36b and 37b (refer FIG. 17), the holding | gripping according to the component precision is carried out when the movable nail parts 5a and 6a are pressed by the fixed nail parts 36 and 37, respectively. The gap in strength is small. That is, even if the holding strength of one of the movable nail parts 6a is strong, the fixed nail part 36 is elastically deformed in the pushing direction, so that it is matched with the holding strength of the other movable nail parts 6a. As a result, Hair loss efficiency is improved because there is no case to be pulled out. At this time, if two sets of fixed nail parts 36 and 37 are formed of an elastic metal part, the hair can be secured cheaply.
    [80] Moreover, since each recessed part 4a provided in the rotating cylinder 4 is formed in the position which shifted all in the axial direction, all the hair loss main unit 32 inserted in the convex part 4a is also in the axial direction. It is provided in the shifted position, and for this reason, as shown in FIG. 20, the hair loss nail part (pair of the fixed nail part 36, 37 and the movable nail part 5a, 6a which are opened and closed) also has a straight line in the circumferential direction They are not positioned side by side, but in axially displaced positions. In this state, as described above, since the gripping positions in one rotation are equally spaced, it is possible to obtain a rotating cylinder 4 having good hair loss efficiency without pulling out.
    [81] Moreover, in order to make the said point stop member 34 and 35 have a role as a skin protection member, the movable nail part 5a, 6a and the fixed nail part 36, 37 directly contact the skin on the upper surface part. Semi-circular circular arc portions 34b and 35b which prevent contact are provided. It is to prevent the shaving of the skin caused by the direct contact between the movable nail portions 5a and 6a and the fixed nail portions 36 and 37.
    [82] In the hair loss apparatus of the illustrated example configured as described above, when the motor 3 is driven while the hair removal head 2 is installed in the main body casing 1, the overload clutch 18 and the gear 19 are mediated as described above. The rotation is transmitted to the furnace gear 15c, and furthermore, the rotation of the gear 15c is transmitted to the gear 41g via the driving gear 40 so that the rotation cylinder 4 rotates.
    [83] 6, the rotation cylinder 4 rotates, and as shown in FIG. 6, the opening / closing levers 38a, 38b, 38c, 38d, 39a, 39b, 39c and 39d turned on at the position of the cam 29. ) Is pressed by the cam 29 and pressed inward against the return spring 370a, so that the opening and closing lever presses the protruding pieces 5c and 6c below the movable nail portions 5a and 6a inward.
    [84] The four movable nail parts 5a and 6a, which are pushed down and rotated inward, are pressed by the fixed nail parts 36 and 37, respectively, so that the movable nail parts 5a and 6a and the fixed nail part 36 are pressed. The hair introduced between the (37) is sandwiched. And hair is pulled out by rotating the rotation cylinder 4 further in the state which pinched | haired. In addition, the next opening / closing lever reaches the place of the cam 29 by the rotation of the rotation cylinder 4, and is pressed by the cam 29, and hair is pulled out as mentioned above.
    [85] Here, as shown in Figs. 14, 17, and 20, the tip portions 36c, 37c in the rotational direction of the fixed nail portions 36, 37 are bent outward in the axial direction, and the movable nail portions 5a are shown. The tip 6d of the rotation direction of the 6a is bent symmetrically with the tips 36c and 37c of the fixed nail parts 36 and 37, so that particularly long hairs are pinched. It is easy to introduce, and the introduction efficiency is high, but only hair is reduced.
    [86] In addition, as shown in FIG. 23, the tip part 5d, 6d of the movable nail part 5a, 6a, and the tip part 36c, 37c of the fixed nail part 36, 37 are rotation cylinders 4, respectively. The tip of the tip 5d and 6d of the movable nail 5a and 6a and the tip of the fixed nail 36 and 37 are smaller than the rotation radius Ra of the rotational nail and are excessively pressed. The shaving of the skin by (36c) (37c) etc. can be prevented, and for this reason, skin feel is good and stability is high.
    [87] In addition, as shown in Fig. 22, circular arc portions 34b and 35b, which serve as skin protection members of the point stop members 34 and 35, are also smaller than the rotation radius Ra of the rotation cylinder 4; As the small diameter Rb, the skin surface is brought into point or line contact with the skin surface, whereby the frictional resistance between the skin and the rotating cylinder 4 becomes small, so that the rotational speed decreases due to excessive torque and the torque increases, The chipping of the skin due to contact friction with the skin is prevented.
    [88] Furthermore, as shown in Fig. 14, both ends of the pressing portions 381a, 381b, 381c and 381d of the opening / closing levers 38a, 38b, 38c and 38d provided in the circumferential direction are opened and closed. Since the ends of the pressing portions 391a, 391b, 391c, and 391d of the levers 39a, 39b, 39c, and 39d overlap in the circumferential direction, opening and closing contributed to sandwiching the hairs. When the cam 29 presses the rear end of the pressing part of the lever in the rotational direction, the front end of the pressing part of the next opening / closing lever is also pressed by the cam 29 at the same time. Thus, the nail parts 5a, 6a, 36 and 37 Although a plurality of) are arranged in the circumferential direction of the rotation cylinder 4, the distance to pull out hairs becomes long.
    [89] Further, the pressing portions 381a, 381b, 381c and 381d of the opening and closing levers 38a, 38b, 38c and 38d and the pressing portions of the opening and closing levers 39a, 39b, 39c and 39d Inclined surfaces 388a and 399a are provided at both ends in the rotational direction of the 391a, 391b, 391c, and 391d to cross the inclined surfaces 388a and 399a of the adjacent open / close levers, thereby suppressing load fluctuations. The noise caused by the rotation of the rotary cylinder 4 can also be suppressed.
    [90] In addition, when the rotation cylinder 4 is rotating and depilation, rotation is transmitted from the gear 15c to the gear 15e to rotate the eccentric cam 15g, and the hair loss block 24 is rotated as described above. Is periodically reciprocated in the axial direction of the rotary cylinder 4 with respect to the base block 15.
    [91] Because of this reciprocating movement, the position of the hair by the fixed nail parts 36 and 37 and the movable nail parts 5a and 6a attached to the rotary cylinder 4 of the hair loss block 24 changes, The hair of the entire skin can be pulled out.
    [92] Here, the fact that the overload clutch 18 is on the main body housing 1 side means that in this kind of large deceleration until the rotation cylinder 4 is reached, the torque to be transmitted by the overload clutch 18 becomes small. In other words, it is not necessary to set the spring force of the clutch spring 182 strongly, and the strength of the locking portion 181b is not required very much, so that the cost of the overload clutch 18 can be reduced.
    [93] In addition, as described above, a gear 19 and a small gear part are provided in the gear 19 which transmits rotation via the overload clutch 18 and becomes the final output part to the hair loss head 2, and the hair loss head is provided. In (2), rotation is received through the small gear of the gear 19, but may be rotated through the large gear of the gear 19. And the hair loss head 2 which receives rotation through the small gear of the gear 19, and the hair removal head which receives rotation through the large gear 19 of the gear 19 are installed, and these are selectively attached to the main body housing 1; In this case, the operation load seen from the load side of the overload clutch is different in both the hair loss heads, and the operating load varies according to the attached hair loss heads. It can be.
    [94] In view of the fact that the torque to be transmitted becomes small, it is most preferable to provide an overload clutch at the position of the output shaft of the motor 3, and from this point of view, as shown in FIG. A knurling part 3b is provided on the output shaft 3a, and a plurality of click pieces 17-2a are provided on the inner circumferential surface of the pinion 17-2 mounted on the outer circumference of the output shaft 3a. When the click 17-2a is engaged with the knurled portion 3b, it transmits the rotation from the motor 3 to the pinion 17-2, and when the overload is in an overload state, the click piece 17-2 is bent. Only the output shaft 3a rotates, and the pinion 17-2 can use suitably so that rotation may not be transmitted.
    [95] Another example is shown in FIGS. 25-27. This installs two overload clutches 18-1 and 18-2 engaged with the pinion 17 provided on the output shaft 3a of the motor 3, while the overload clutch 18-1 is gear 19. The power is transmitted to the hair loss head 2 side through the medium, and the overload clutch 18-2 is shown to transmit power to the hair loss head 2 side via the gear 19-2. All of the overload clutches 18-1 and 18-2 have the same configuration as the overload clutch 18 described above, and 18-3 in the figure is a separator. Since the gear 19 is provided with the large gear part and the small gear part similarly to the said gear 19, as shown in FIG. 25, it transmits power to the hair loss head 2 side through the small gear of the gear 19. As shown in FIG. In addition, three states can be selectively obtained: a state of transmitting power through the large gear part of the gear 19, and a state of transmitting power through the gear 19-2.
    [96] Incidentally, Fig. 26 shows a state in which the shaver head SH is attached to the main body housing 1, in which the rotation transmitted from the overload clutch 18-1 to the gear 19 is compared with the gear 19. The eccentric shaft S4, which is transmitted from the gear S7 meshing with the gear part via the gear S6 to the rotating body S5, and which is installed on the swivel table S5, is freely supported by the driver S3. By reciprocating, the inner blade block S2 in contact with the inner surface of the outer blade S1 is reciprocated and slid.
    [97] In addition, FIG. 27 shows the state in which the hair loss head AH, in which the hair loss rotating cylinders (not shown) are arranged before and after the boundary plate A5, is attached to the main body housing 1, wherein the shaft ( The gear 19-2 supported at 19k is engaged with the gear A1, and the rotation of the gear A1 is transmitted to the two rotary cylinders via the gears A2, A3, A4 and the like. It is shown.
    [98] As described above, in the invention according to claim 1, the main body housing incorporating the drive source and the rotation cylinder rotated and driven by the drive source are installed in the head freely detachable from the main body housing. A depilation device in which a hair removal nail portion is provided and the hair pinched by the nail portion is pulled out by the rotation of a rotating cylinder, the power transmission is cut off at the time of overload between the power transmission output portion and the driving source toward the head in the main body housing. Since an overload clutch is provided, the torque that must be transmitted by the load clutch is reduced, so that the components of the overload clutch are not required to reduce the cost of the overload clutch. Because you do not have to install space in head, It can be reduced and the use of DE can be a great convenience.
    [99] In the case where the plurality of heads are selectively detachable from the main body housing, the overload clutch provided in the main body housing becomes effective for all the heads, and the overload clutch is incorporated in all of the plurality of heads. In comparison, the overall cost can be significantly lowered.
    [100] In addition, it is preferable that the overload clutch is an automatic return type that returns with overload elimination from the viewpoint of convenience of use for this kind of household goods.
    [101] In addition, power transmission gears are used as operating members, in particular gears located close to the driving source in the power transmission system as operating members, or front gears with spring force applied in the axial direction as operating members. It is preferable from the viewpoint of reducing the constituent members of the overload clutch.
    [102] Furthermore, if the operating load seen from the load side of the overload clutch is variable, especially if the operating load seen from the load side is variable according to a plurality of types of blade heads that are selectively detachable from the main body housing, the plurality of heads It is possible to set different operating loads, and even though the overload clutch is built in the main body housing side, it is possible to set the operating loads according to each head.
    [103] In this case, the main body housing can be suitably used in which a plurality of output sections corresponding to the plurality of blade heads are individually provided, and a plurality of overload clutches corresponding to the plurality of blade heads in the main body housing are provided. It may be done.
