PROBLEM TO BE SOLVED: To provide a vehicle skeleton structure which attains higher rigidity against a collision load input from a vehicle front side to a vehicle.SOLUTION: A widening part 54 formed at a rear part 45 of a floor frame 42 and a widening part 66 formed at a front part 63 of a rear side member 60 are disposed at the same position in a vehicle width direction. The widening part 66 of the rear side member 60 is coupled to a locker 24 and a floor lower cross member 46. In other words, in the embodiment, the locker 24, the floor frame 42, the floor lower cross member 46, and the rear side member 60 are coupled to each other at the same position (a coupling part 70). The structure increases bonding power of the floor frame 42, the locker 24, the floor lower cross member 46, and the rear side member 60 which are skeleton members to further improve strength and rigidity in these members.SELECTED DRAWING: Figure 1

    【課題】車両前方側から車両へ入力された衝突荷重に対して、さらに高い剛性を得ることができる車両骨格構造を提供する。【解決手段】フロアフレーム42の後部45に形成された拡幅部54とリアサイドメンバ60の前部63に形成された拡幅部66が、車両幅方向の同じ位置に配置されている。そして、このリアサイドメンバ60の拡幅部66は、ロッカ24及びフロア下クロスメンバ46と結合されている。すなわち、本実施形態では、ロッカ24、フロアフレーム42、フロア下クロスメンバ46及びリアサイドメンバ60が同じ箇所(結合部70)で互いに結合している。これにより、いわゆる骨格部材であるフロアフレーム42、ロッカ24、フロア下クロスメンバ46及びリアサイドメンバ60の結合力を上げ、これらの部材において強度及び剛性をさらに向上させることができる。【選択図】図1
