BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for a vehicle spare tire in which a spare tire is mounted on an outer surface of a vehicle body panel.

[0002]

2. Description of the Related Art For example, in a wagon type automobile, a spare tire may be mounted on a back door which opens and closes a rear end opening of a vehicle body. In this case, if the spare tire is mounted in a state where the spare tire is exposed, raindrops from the spare tire tend to stain the vehicle body panel, the bumper, and the like, resulting in a problem that the appearance is deteriorated.

In order to prevent the appearance from being deteriorated due to such dripping, for example, Japanese Unexamined Utility Model Publication No. Hei 6-78174 discloses a front cover disposed between a vehicle body panel and a spare tire. There has been proposed a configuration in which the entire spare tire is covered by a rear cover hinged to the rear cover. However, in the structure in which the entire spare tire is covered with the cover member, the cover member becomes large,
There is a problem that costs increase.

Accordingly, the present applicant has proposed a spare tire support structure which can prevent rain dripping with a simple structure (see Japanese Patent Application No. 8-255921). As shown in FIG. 6, a cover member 52 that covers a lower portion of the spare tire 51 on the vehicle body panel side is disposed between the vehicle body panel 50 and the spare tire 51, and is fixed to the vehicle body panel 50 by bolting. The outer edge 52a of the cover member 52 is projected outward from the bumper 53.

According to this, the dripping from the spare tire 51 is discharged from the outer edge 52a of the cover member 52, so that it can be prevented from adhering to the vehicle body panel 50 and the bumper 53. Further, the cover member 52 has a simple structure that covers only the lower portion of the spare tire 51, and costs can be reduced as compared with a structure that covers the entirety.

[0006]

However, in the structure in which the cover member is disposed between the vehicle body panel and the spare tire, the cover member is attached to the cover member as shown by an arrow in FIG. May flutter,
There is a concern that the vehicle body panel may be damaged or noise may occur.

[0007] In addition, since the above-mentioned fluttering tends to generate a large stress in the vehicle body mounting portion of the cover member, it is necessary to increase the strength of the mounting portion, and in some cases, the weight increases and the cost increases. Problems arise.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional situation, and it is necessary to prevent the cover member from being damaged due to fluttering and to generate abnormal noise, and it is necessary to increase the mounting strength by reducing the stress of the mounting portion. It is intended to provide a support structure for vehicle spare tires.

[0009]

According to the present invention, a spare tire is removably mounted on a carrier fixed to a vehicle body panel, and at least a lower portion of the spare tire on a vehicle body panel side is provided between the spare tire and the vehicle body panel. In a support structure for a vehicle spare tire having a cover member disposed thereon, an elastic member is attached to the cover member, and when the spare tire is mounted on a carrier, the spare member and the vehicle body panel form the elastic member. The cover member is sandwiched between the two.
