PROBLEM TO BE SOLVED: To improve rigidity and vibration restricting function of a rear floor panel on which a seat cushion for a rear seat is arranged, without using a reinforcing cross member, to achieve reductions in weight and cost by decreasing the number of components and man hours for mounting, and to disperse a load on the rear floor panel in the forward and backward directions of the vehicle and in a width direction of the vehicle.SOLUTION: The front part of a rear floor panel 2 is joined to the rear part of a main floor panel 1. An upward extending vertical wall 31 is formed on the front side of the rear floor panel 2. A seat cushion 61 for a rear seat 6 is arranged on the upper part of the rear floor panel 2 of the vertical wall 31, which is located in the rear of the vehicle. The front end part of the seat cushion 61 and the upper part of the vertical wall 31 are provided substantially in the same position in the forward and backward directions of the vehicle. On the vehicle rear side of the vertical wall 31, a front-side width direction bead part 41 extending in the vehicle width direction and protruding upward in the vehicle, is provided. On the width direction central part of the vehicle, a forward and backward bead part 42 extending in the forward and backward directions of the vehicle and protruding upward in the vehicle, is provided.
【課題】補強用のクロスメンバを用いることなく、リヤシートのシートクッションが配置されるリヤフロアパネルの剛性及び振動抑制機能を向上させ、部品点数及び取付工数の削減によって軽量化及びコストダウンを図り、リヤフロアパネルへの荷重を車両前後方向及び車両幅方向に分散させることにある。【解決手段】メインフロアパネル1の後部にリヤフロアパネル2の前部が接合され、リヤフロアパネル2の前方側に上方へ延びる縦壁31が形成され、縦壁31の車両後方に位置するリヤフロアパネル2の上部にリヤシート6のシートクッション61が配置されており、シートクッション61の前端部と縦壁31の上部とは、車両前後方向でほぼ同じ位置に設けられ、縦壁31の車両後方側には、車両幅方向に沿って延び、車両上方へ突出する前方側幅方向ビード部41が設けられ、車両幅方向中央部には、車両前後方向に沿って延び、車両上方へ突出する前後方向ビード部42が設けられている。【選択図】図2
