Is joined to the side member 1.

クォータインナパネル６よりも外側には、図３に示すリヤピラーリンフォース２５が図２，図５に示すように接合される。リヤピラーリンフォース２５は、上部２５ａがクォータインナパネル６と接合されている。ホイールハウス４の開口８の部位には、図４に示すハット型断面形状のリヤホイールハウスインナリンフォース２１が配置される。リヤホイールハウスインナリンフォース２１は、図２，図５に示すように、リヤホイールハウスインナパネル５よりも車両外側に配置され、その上端２１ａがリヤピラーリンフォース２５の下部２５ｂに接合され、その下端２１ｂが開口８から内方に進入して、リヤホイールハウスインナパネル５の下部５ｂ側に形成されたサスペンション取付部１０の下方に重合して接合されている。つまり、リヤホイールハウスインナリンフォース２１の下端２１ｂはリヤホイールハウスインナパネル５の下部５ｂに接合されている。   The rear pillar reinforcement 25 shown in FIG. 3 is joined to the outside of the quarter inner panel 6 as shown in FIGS. The rear pillar reinforcement 25 has an upper portion 25 a joined to the quarter inner panel 6. A rear wheel house inner force 21 having a hat-shaped cross section as shown in FIG. 4 is disposed at a portion of the opening 8 of the wheel house 4. As shown in FIGS. 2 and 5, the rear wheel house inner reinforcement 21 is disposed on the vehicle outer side than the rear wheel house inner panel 5, and an upper end 21a thereof is joined to a lower portion 25b of the rear pillar reinforcement 25, and a lower end thereof. 21b enters inward from the opening 8 and is overlapped and joined below the suspension attachment portion 10 formed on the lower 5b side of the rear wheel house inner panel 5. That is, the lower end 21 b of the rear wheel house inner reinforcement 21 is joined to the lower part 5 b of the rear wheel house inner panel 5.

本形態では、このようなリヤピラーリンフォース２５とリヤホイールハウスインナリンフォース２１とを連続断面となるように溶接等で固定して接合し、クォータインナパネル６とリヤホイールハウスインナパネル４と相まって、垂直方向への断面が、図５に示すように閉断面構造となるようにしている。   In this embodiment, such a rear pillar reinforcement 25 and the rear wheel house inner force 21 are fixed and joined by welding or the like so as to have a continuous cross section, and coupled with the quarter inner panel 6 and the rear wheel house inner panel 4, The cross section in the vertical direction has a closed cross section structure as shown in FIG.

図１、図５に示すように、ホイールハウス４の上方には、車幅方向に延びるリヤシェルフ３１が配置されている。リヤシェルフ３１の両端部は、左右のホイールハウス４の上部の車体壁面となるリヤホイールハウスインナパネル５とクォータインナパネル６との接合部に接合されていて、車体のねじり剛性が確保されている。リヤシェルフ３１の端部は板状部材としてのリヤシェルフアッパブレース３２とクロスメンバ部材としてのバルクヘッドブレース３３とで構成されている。リヤシェルフ３１は、車幅方向に延びるリヤシェルフパネル３５の下側に車幅方向に延びるクロスメンバ部材としてのリヤシェルフエクステンション３６の縁部が接合され、リヤシェルフパネル３５と共に車幅方向に垂直な断面が閉断面となるリヤシェルフ閉断面部が形成されている。   As shown in FIGS. 1 and 5, a rear shelf 31 extending in the vehicle width direction is disposed above the wheel house 4. Both end portions of the rear shelf 31 are joined to the joint portion between the rear wheel house inner panel 5 and the quarter inner panel 6 which are the vehicle body wall surfaces at the upper part of the left and right wheel houses 4, and the torsional rigidity of the vehicle body is ensured. . The end portion of the rear shelf 31 includes a rear shelf upper brace 32 as a plate-like member and a bulkhead brace 33 as a cross member member. The rear shelf 31 has an edge of a rear shelf extension 36 as a cross member member extending in the vehicle width direction joined to a lower side of the rear shelf panel 35 extending in the vehicle width direction, and is perpendicular to the vehicle width direction together with the rear shelf panel 35. A rear shelf closed cross section having a closed cross section is formed.

このような構成の車両後部の車体構造によると、リヤピラーリンフォース２５とリヤホイールハウスインナリンフォース２１をリヤホイールハウスインナパネル５よりも車幅方向に外側に配置し、リヤピラーリンフォース２５の下部２５ｂとリヤホイールハウスインナリンフォース２１の上部２１ａとを溶接等で接合して連続した一体断面を成形し、リヤホイールハウスインナリンフォース２１の下部２１ｂをスプリングハウス９と重合させて接合し、これら一体化されたリヤホイールハウスインナリンフォース２１及びリヤピラーリンフォース２５と、互いに接合されて一体化された断面を構成するクォータインナパネル６とリヤホイールハウスインナパネル５とで閉断面構造を構成するようにしたので、スプリングハウス９から連続的な断面が、リヤホイールハウスインナパネル５よりも車外側に形成される。このため、サスペンション装置５０からの上下方向への入力荷重が、車体剛性部材となるリヤピラー７に対して分散する構造を採りながらも従来に比べて車室内空間を確保できる。また、従来のようにリヤシェルフ３１に補強部材を接合しないため、リヤシェル３１廻りの構造が合理化でき、板厚の低減や断面縮小が可能となり、軽量化を図ることができる。   According to the vehicle body structure of the rear portion of the vehicle having such a configuration, the rear pillar reinforcement 25 and the rear wheel house inner reinforcement 21 are disposed outside the rear wheel house inner panel 5 in the vehicle width direction, and a lower portion 25b of the rear pillar reinforcement 25 is provided. And the upper portion 21a of the rear wheel house inner force 21 are joined by welding or the like to form a continuous integral cross section, and the lower portion 21b of the rear wheel house inner force 21 is overlapped with the spring house 9 and joined together. The closed rear wheel house inner force 21 and rear pillar reinforcement 25, and the quarter inner panel 6 and the rear wheel house inner panel 5 that are joined together to form a closed cross section constitute a closed cross-sectional structure. So, from spring house 9 continuous Surface is formed outside of the vehicle than the rear wheel house inner panel 5. For this reason, it is possible to secure a vehicle interior space as compared with the conventional case while adopting a structure in which the input load in the vertical direction from the suspension device 50 is dispersed with respect to the rear pillar 7 serving as the vehicle body rigid member. Further, since the reinforcing member is not joined to the rear shelf 31 as in the prior art, the structure around the rear shell 31 can be rationalized, the plate thickness can be reduced and the cross section can be reduced, and the weight can be reduced.

図５において、サイドメンバ１は、サイドメンバロア２とリヤフロアパネル３とで閉断面構造としたが、図６に示すように、サイドメンバロア２とサイドメンバアッパ６０とを用いて互いに接合して閉断面構造とし、リヤフロアパネル３の端部をサイドメンバアッパ６０に接合した構成としても良い。   In FIG. 5, the side member 1 has a closed cross-sectional structure with the side member lower 2 and the rear floor panel 3. However, as shown in FIG. 6, the side member 1 is joined to each other using the side member lower 2 and the side member upper 60. A closed cross-sectional structure may be used, and the end of the rear floor panel 3 may be joined to the side member upper 60.

図５，図６に示す構成では、リヤホイールハウスインナパネル５の下部５ｂは、サイドメンバ１を構成するリヤフロアパネル３の端部あるいはサイドメンバアッパ６０にそれぞれ接合したが、図７に示すように、サイドメンバ１との間にブラケット４０を介してサイドメンバ１側と接合する形態としても良い。この場合ブラケット４０にサスペンション取付部１０Ａを形成し、リヤホイールハウスインナリンフォース２１の下部２１ｂと重合させて接合することで、サスペンション取付部１０Ａの強度を高めることができる。   5 and 6, the lower portion 5b of the rear wheel house inner panel 5 is joined to the end of the rear floor panel 3 constituting the side member 1 or to the side member upper 60, respectively, but as shown in FIG. The side member 1 may be joined to the side member 1 via the bracket 40. In this case, the suspension mounting portion 10A is formed on the bracket 40 and is superposed on the lower portion 21b of the rear wheel house inner force 21 so as to be joined to increase the strength of the suspension mounting portion 10A.
