As illustrated in FIG . 3, the support portion 51 comprises two fixing portions 511 to which the damper 15 is fixed by bolts, and a through hole 512 in which a pin 151 of the damper 15 is inserted. The through hole 512 is disposed between the two fixing portions 511 which are aligned in the direction X.
    The details of the junction structures and position relationships of the parts of the wheel housing structure 1 are described below.
    [Junction structure of the inner panel and the support] As illustrated in FIG. 4, the inner panel 2 comprises a first portion of plate 22 which extends in the plane ZX, a second portion of plate 23 which extends upwards from an upper end of the first portion of plate 22 outwards in the Y direction, a third plate portion 24 which extends upwards from an upper end of the second plate portion 23 and a fourth plate portion 25 which extends upwards from an upper end of the third plate plate portion 24 outward in the Y direction. An upper end of the fourth plate portion 25 has a flange shape and is joined to the outer panel 3.
    The support 5 comprises a support plate portion 52 comprising the support portion 51 formed thereon and extending in an XY plane, an upper plate portion 53 which extends upwards from one end exterior of the support plate portion 52 in the Y direction, and a bottom plate portion 54 which extends downward from an interior end of the support plate portion 52 in the Y direction.
    The lower plate portion 54 of the support 5 is superimposed on an outer side of the first plate portion 22 of the inner panel 2 in the direction Y. A damper reinforcement 16 serving as a reinforcement element is superimposed, from the upper end of the first plate portion 22 has the second plate portion 23, on an inner side of the interior panel 2 in the Y direction. The support plate portion 52 of the support 5 is arranged under the second plate portion 23 of the inner panel 2 with an interval between them. A shock absorber patch 17 serving as reinforcing plate material is superimposed on an upper surface of the support plate portion 52. With regard to the third plate portion 24 of the interior panel 2, the upper plate portion 53 of the support 5 is superimposed towards the outside in the Y direction, while the main body plate portion 41 of the internal reinforcement of the rear upright 4 is superimposed towards the inside in the Y direction.
    Three superimposed portions of the main body plate portion 41, the third plate portion 24 and the upper plate portion 53 are joined by spot welding, whereby a first junction portion SP1 is formed. The first junction portion SP1 is located on an outer side of the support portion 51 as a shock absorber support position in the Y direction, and above the support portion 51 in the Z direction. Three overlapping portions of the reinforcement shock absorber 16, the first plate portion 22 and the lower plate portion 54 are joined by spot welding, whereby a second junction portion SP2 is formed. The second junction portion SP2 is located on an inner side of the support portion 51 as a shock absorber support position in the Y direction and below the support portion 51 in the Z direction.
    The second plate portion 23 and the support plate portion 52 are separated from each other, and the first plate portion 22 and the upper plate portion 53 are separated from each other , whereby a closed cross section is formed between the support 5 and the interior panel 2. In the interior reinforcement of the rear upright 4, the main body plate portion 41 extends upward from the first junction portion SP1 and its upper end is joined to the roof rail 14.
    [Junction structure of the rear post interior reinforcement 4 and the roof rail 14] The upper end of the rear post interior reinforcement 4 is joined to the roof rail 14. The rear post interior reinforcement 4 has the same shape on a front side and a back side in the X direction, and the shape on the front side is mainly described below.
    As illustrated in FIG. 5, the rear post internal reinforcement 4, at its upper end, comprises a wide plate portion 42 which is continuous with, and wider than, the main body plate portion 41 (larger in the direction X), a outer extension plate portion 43 which is continuous with a lower end of the wide plate portion 42 and extends outward in the Y direction, and a flange-shaped plate portion 44 which is continuous with a outer end of the outer extension plate portion 43 and extends downward. The upper end of the rear post inner reinforcement 4 is inclined downwards towards the rear in the direction X.
    The wide plate portion 42 and the flange-shaped plate portion 44 extend (in the plane ZX) so as to be substantially perpendicular to the direction Y, and serve as portions of plates turned to the side. The outer extension plate portion 43 extends so as to cross with the direction Z while having a slight inclination relative to the plane XY, and serves as a portion of plate turned upwards and downwards. The wide plate portion 42 and the flange-shaped plate portion 44 as side-facing plate portions are separated from each other in the Y direction, and the outer extension plate portion 43 is arranged between them. Consequently, the interior rear pillar reinforcement 4 has a stepped shape.
    The roof rail 14 comprises a portion superimposed on an outer side of the wide plate portion 42 in the direction Y, a portion superimposed on an upper side of the portion of outer extension plate 43 and a portion superimposed on an outer side of the flange-shaped plate portion 44 in the Y direction, so that the roof rail 14 has a stepped shape similar to that of the interior rear pillar reinforcement 4. The internal rear pillar reinforcement 4 and the roof rail 14 are joined by spot welding of the superimposed portions as described above.
    [Position relation between the interior panel and the floor panel] A bead portion 211 which extends downwards from the second junction portion SP2 in the direction of the floor panel 13 is formed in the inner curved portion 21 of the inner panel 2. The bead portion 211 is a portion formed in the inner curved portion 21 so as to be more curved inwards in the Y direction.
    The floor panel 13 comprises a portion which extends further downwards from a junction portion with the interior panel 2 and is formed in a hollowed out shape, seen from above. A cross member 132 is provided on an upper surface of a bottom plate 131 in the recessed portion of the floor panel 13. The cross member 132 extends in the direction Y.
    When viewed from the Y direction, a position in the X direction of a lower end of the bead portion 211 coincides substantially with a position in the X direction of the cross member 132. That is to say say that a position relation is such that a line extending the bead portion 211 downwards and a line extending the cross member 132 outwards in the Y direction intersect one with the 'other.
    [Junction structure of the inner panel and the striker support] As illustrated in FIG. 6, the striker support 12 includes a flange portion 121 along the inner curved portion 21 of the inner panel 2. The damper reinforcement 16 is superimposed on an inner side of the inner curved portion 21 in the Y direction, and the flange portion 121 is superimposed on the other interior side. In this way, the three superimposed portions are joined by spot welding.
    Since the shock absorber reinforcement 16 is joined to the striker support 12, a load implemented on the shock absorber reinforcement 16 is thus transmitted to the striker support 12. The striker support 12 extends in the direction Z and an upper end thereof is joined to the inner wing panel 11. Consequently, the load applied to the shock absorber 15 and transmitted to the shock absorber reinforcement 16 is transmitted to the inner wing panel 11 by the striker support 12.
    The following effects are obtained according to the embodiment. That is to say that, in the first junction portion SP1 situated above the support portion 51 supporting the damper 15 by the support 5, since the support 5 is joined not only to the interior panel 2 but also to the rear post interior reinforcement 4, a load in the direction Z implemented on the shock absorber 15 can be directly transmitted to the rear post internal reinforcement 4. In addition, since the rear post internal reinforcement 4 is provided for extend over the interior panel 2 and the aforementioned roof rail 14, the load in the direction Z applied to the shock absorber 15 can be easily transmitted to the roof rail 14 above via the interior reinforcement of the rear upright 4.
    The first junction portion SP1 is formed at the level of the superposed portions of the third plate portion 24, of the upper plate portion 53 and of the main body plate portion 41, all the plate portions extending in the Z direction, so that a deformation of the periphery of the first junction portion SP1 due to the load in the Z direction applied to the damper 15 hardly occurs, and the load is easily transmitted to the roof rail 14 .
    Since the rear post interior reinforcement 4 extends upwards from the first junction portion SP1 and is joined to the roof rail 14, the application of load to the shock absorber 15 is easily transmitted to the roof rail 14 located above.
    The rear post interior reinforcement 4, at its upper end, or the rear post reinforcement 4 is joined to the roof rail 14, comprises the wide plate portion 42 and the flange-shaped plate portion 44 which s 'extend so as to cross direction Y, and the outer extension plate portion 43 which extends so as to cross direction Z. Since the stepped shape is formed in the interior reinforcement of rear upright 4, the resistance to loads in different directions and that against torsional deformation can be improved in a junction portion between the interior reinforcement of the rear upright 4 and the roof bar 14.
    Since the inner panel 2 includes the bead portion 211 which extends from the second junction portion SP2 to the floor panel 13 located below, the load in the Z direction applied to the damper 15 can be transmitted to the floor panel 13 by the bead portion 211.
    The invention is not limited to the above embodiment, but includes other configurations and the like capable of achieving the object of the invention, and the following modifications and the like are also included in the 'invention.
    For example, in the above embodiment, the third plate portion 24, the upper plate portion 53 and the main body plate portion 41 which form the first junction portion SP1 extend in the Z direction. However, the plate portions where the first junction portion is formed may have a slight inclination (for example, an inclination of 45 ° or less) relative to the Z direction, or may extend in the XY plane. .
    In the above embodiment, the rear post interior reinforcement 4 extends upwards from the first junction portion SP1 and is joined to the roof rail 14. However, the rear post internal reinforcement can extend obliquely to the vertical direction to be joined to the roof rail 14, or may be joined to the roof rail 14 with a bent portion extending in another direction.
    In the above embodiment, the rear post inner reinforcement 4 includes the wide plate portion 42, the flange-shaped plate portion 44 and the outer extension plate portion 43, whereby the stepped form is formed. However, the junction structure between the reinforcing element and the chassis element can be any suitable structure. For example, when sufficient strength can be guaranteed by using another reinforcing member, the reinforcing member may not have a stepped shape.
    In the above embodiment, although the position in the X direction of the bead portion 211 coincides substantially with the position in the X direction of the cross member 132 of the floor panel 13, the position of the portion the bead can be appropriately defined depending on the shape, number and the like of the sleeper. For example, when a plurality of sleepers is provided, the position in the X direction of the bead portion can be defined between positions in the X direction of two sleepers.
    In addition, the bead portion may not be formed in the interior panel. For example, when a strip-like reinforcing element which extends in the direction Z is provided in the interior panel, the load input on the shock absorber 15 can be transmitted to the floor panel 13 by the reinforcing element of the strip plate type.
    Although the best configuration, the best method and the like for implementing the invention are disclosed in the description above, the invention is not limited to it. That is to say that, although the invention has been illustrated specifically and described mainly with respect to a particular embodiment, various modifications can be made by those skilled in the art to the embodiment described above in form, material, quantity and other detailed configurations without departing from the spirit and scope of the invention. Therefore, the description which limits the form, material and the like described above is given by way of example to facilitate understanding of the invention, and the invention is not limited thereto. Accordingly, the description of names of elements in addition to some or all of the limitations of shape, material and the like is included in the invention.
