DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a mounting portion for a spare tire hanger disposed at a rear portion of a vehicle body.

[0002]

2. Description of the Related Art Conventionally, a structure shown in FIG. 3 has been proposed as a mounting portion for a spare tire hanger disposed at a rear portion of a vehicle body (see Japanese Utility Model Laid-Open No. 2-15087).
That is, the vehicle body 50 has an opening 51 at its rear end and a back door 52 that opens and closes the opening 51. A side body of the back door 52 is provided with a vehicle body outer plate 54 constituting a side edge of the opening 51 and a rear pillar 53 and the like. A rain force 55 is spot-welded inside the vehicle body outer plate 54. ing. The reinforce 55 has a shape surrounding a housing 56 in which the rear combination lamp is housed and arranged.
7 are provided.

On the other hand, the spare tire hanger 58 is a substantially U-shaped member that is laid down, on which a spare tire 59 is removably mounted and hinges 60, 6 are provided at its ends.
0 is provided. Such a spare tire hanger 58
By being fixed to the pivots 57, 57, the hinges 60, 60 are horizontally rotatably attached to the rear portion of the vehicle body 50.

In such a structure, the spare tire hanger 58 is subjected to the weight of the spare tire 59 or a load caused when the spare tire 59 vibrates up and down during traveling.
The stress of the load applied to the spare tire hanger 58 acts intensively on the connection point with the hinge 60 in the vehicle body 50. However, since the vehicle body 50 is provided with the reinforce 55 having the pivotal support 57 to which the hinge 60 is fixed, the reinforce 55 ensures the rigidity against the stress at the rear portion of the vehicle body 50. You. Thereby, the spare tire hanger 58 can be supported without causing local deformation of the vehicle body 50. Further, the rigidity around the housing 56 is ensured by the reinforce 55, whereby deformation around the housing 56 when the stress is input is suppressed, and
It is possible to prevent damage to the rear combination lamp housed and arranged in the vehicle.

[0005]

However, in such a conventional structure, the pivot 57 is formed integrally with the reinforce 55. For this reason, in order to increase the rigidity of the pivotal support portion 57 in order to secure the rigidity of the pivotal support portion 57 that can resist the stress acting intensively, the entire reinforcement 55 must be thickened. As a result, the weight of the reinforce 55 increases, which contributes to an increase in the weight of the vehicle body. In addition, the use of a large amount of expensive thick steel plates increases the manufacturing cost.

Further, since the size of the spare tire 59 used for the vehicle differs depending on the specifications of the vehicle,
The load applied to the spare tire hanger 58 also varies depending on the specifications. Therefore, on the manufacturer side, in order to ensure the strength according to the load applied to the spare tire hanger 58, a plurality of types of large-scale reinforces 55 having different wall thicknesses are separately prepared and prepared. It is necessary to selectively use those that correspond to the specifications. Therefore, a large space is required for separately storing a plurality of types of large-size reinforces 55, which is one of the causes of a decrease in space efficiency in the factory. Furthermore, since the reinforcement 55 is spot-welded to the vehicle body outer plate 54, welding dents appear on the vehicle body surface, and the appearance quality of the vehicle body 1 is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and it is possible to reduce the cost without increasing the weight of the reinforce, the appearance quality of the vehicle body, and the space efficiency in the factory. It is an object of the present invention to provide a spare tire hanger mounting portion structure for a vehicle body that can sufficiently secure the support rigidity of the spare tire hanger.

[0008]

According to the present invention, a first reinforcement having a shape surrounding a housing in which a rear combination lamp is accommodated is spot-welded to an inner plate of a vehicle body. Disposing a second reinforce along an upper edge of the housing above the first reinforce, and spot welding the second reinforce to the first reinforce and the housing; A third reinforcement is disposed below the first reinforcement along a lower edge of the housing, and
A reinforcement is spot-welded to the first reinforce and the housing, and the second and third reinforces are provided with pivot portions of a spare tire hanger.

[0009]

In the above structure, since the first reinforcement has a shape surrounding the housing for accommodating the rear combination lamp, the rigidity around the housing is secured by the first reinforcement. Further, the pivot portions of the spare tire hanger are provided on the second and third reinforces respectively arranged on the upper and lower portions of the first reinforce. Therefore, the large first
Even if plural kinds of reinforcements are not prepared, plural kinds of second and third reinforcements different in rigidity, which are smaller than the first reinforcement, are prepared, and if these are selectively used, they can be added to the pivot. Appropriate rigidity can be ensured according to the load. Further, since the first reinforce is spot-welded to the inner plate of the vehicle body and the second and third reinforces are spot-welded to the first reinforce,
No welding dents occur on the outer plate of the vehicle body.
