To effectively upgrade the rigidity of a portion of a vehicle rear part whose collision performance is desired to be upgraded while suppressing an increase in a weight.SOLUTION: A vehicle rear structure includes: a floor panel 10; and side members 20 disposed on external sides in a width direction of the floor panel 10. A tail end member 30 extending in the width direction is joined to the rear ends of the side members 20. Swollen parts 25 swollen downward in a vehicle as proceeding rearward in the vehicle are formed respectively in rear parts of the side members 20. A length in the width direction of a bottom 25a of the swollen part 25 is configured to be smaller than a bottom 21a of the side member 20 located in front of the swell part 25 in the vehicle.SELECTED DRAWING: Figure 3

    【課題】重量増加を抑制しつつ、車両後部における衝突性能を向上させたい部分の剛性を効果的に向上させる。【解決手段】車両後部構造は、フロアパネル10と、フロアパネル10の幅方向両外側に設けられるサイドメンバ20とを備え、サイドメンバ20の後端には、幅方向に延びるテールエンドメンバ30が接合されている。サイドメンバ20の後部には、車両後方に向かうに従い車両下方に膨出する膨出部25が設けられ、膨出部25の底面25aの幅方向の長さは、膨出部25よりも車両前方に位置するサイドメンバ20の底面21aに対して、より小さく設定されている。【選択図】図3
