Therefore, the front part of the rear wheel house 11 is firmly connected to the rear part of the side sill reinforcing member 50 at a plurality of positions.
  • the closed closed cross section 22 by the wheel house reinforcing member 14 can be connected to the closed cross section of the side sill 10 with high rigidity. Therefore, when this configuration is adopted, it is possible to efficiently increase the rigidity from around the rear wheel house to the side sills 10.

Abstract

La présente invention concerne un passage de roue arrière (11) comprenant une partie interne de passage de roue arrière (11I) et une partie externe de passage de roue arrière (11O). Un élément de renfort de passage de roue (14) comprend : une partie corps d'élément de renfort (14h) qui, conjointement avec une paroi de base externe (11O-b) de la partie externe de passage de roue arrière, forme une section transversale fermée de renfort (22) ; une partie jonction externe qui est assemblée à la surface externe de la paroi de base externe ; et une partie de jonction interne qui s'étend vers l'extérieur dans la direction radiale de la roue arrière. La paroi de base externe (11O-b) est disposée de manière décalée plus loin vers le côté axe de la roue arrière par rapport à une paroi de base interne (11I-b). La partie de jonction interne est disposée sur le côté inverse de la surface de jonction d'une paroi verticale externe (11O-a) à une paroi verticale interne (11I-a), et est assemblée à la paroi verticale externe (11O-a) et à la paroi verticale interne (11I-a) tout en formant une structure à trois couches avec celle-ci.
