煩雑となり、装造上不利となるため、この構造を簡略化
し、コストダウンや軽量化を計った設計が提案されてい
る。In the body structure of an automobile, a particularly large load is applied to the portion where the wheel suspension device is attached, so it is necessary to increase the strength of this attachment portion. In particular, since the rear wheel suspension system is attached below the floor of the vehicle body, it is necessary to reinforce this portion of the floor. Conventionally, various floor structures have been known in which the mounting portion of the rear wheel suspension system is reinforced. These reinforcing structures are structurally complex and require complicated assembly work, which is disadvantageous in terms of installation.Therefore, designs have been proposed to simplify this structure and reduce cost and weight.
例えば実開昭５４ − ５９６２２号には、強度の大き
い閉断面構造のサイドシルにリヤサイドメンバーを固着
し、この剛性の高い部分を後輪懸架装置の取付部とした
構造が示されている。For example, Japanese Utility Model Application Publication No. 54-59622 discloses a structure in which a rear side member is fixed to a side sill having a closed cross-section structure with high strength, and this highly rigid part is used as an attachment part for a rear wheel suspension system.

がある。さらに、リヤサイドメンバーに大荷重がかかっ
た場合、リヤサイドメンバー全体がねじれることも考え
られ、実用上強度に問題がある。However, although this structure has been simplified, the load on the lower surface of the rear side member, that is, the part where the suspension system is attached, is entirely borne by the fixed part between the rear side member and the side sill, and this fixed part can peel off. This poses a problem in terms of structural strength. Furthermore, if a large load is applied to the rear side member, the entire rear side member may be twisted, which poses a practical strength problem.
本発明はこれらの問題点に鑑み、構造を簡単として製造
コストを低くする一方、実用上十分な強度を備えた後部
車体構造を提供することを目的とするものである。SUMMARY OF THE INVENTION In view of these problems, it is an object of the present invention to provide a rear vehicle body structure that has a simple structure and low manufacturing costs, and has sufficient strength for practical use.

したことを特徴とするものである。In the rear vehicle body structure of the present invention, a rear side member is fixed to a side sill having a closed section structure with high strength, a reinforcing plate is placed over the rear side member, and the left and right edges of this reinforcing plate are attached to the rear side member and the side sill. In addition, a vertical surface bent upward is formed at the rear of this reinforcing plate, and this vertical surface forms a joint that partitions the space between the rear side member and the floor into front and back parts. The present invention is characterized in that a bracket for mounting a rear wheel suspension device is fixed below the overlapping portion of the side member.

る。In this way, a reinforcing plate with the side edges fixed to both the side sill and the side member is provided, and the rear part of this reinforcing plate is bent upward to form a knot, so the strength of this part is significantly increased. This makes it possible to sufficiently withstand the large load applied from the rear wheel suspension system, thereby realizing a vehicle body structure that is practically strong and simplified.
