The invention provides a vehicle body rear portion structure which can fully absorb impact load input to the rear portion of a vehicle body without increasing the weight of the vehicle. A vehicle body rear structure is provided with: a pair of left and right rear side frames (2) extending substantially in the front-rear direction of a vehicle; and a rear floor panel (3) coupled to the pair of rear side frames (2) in a front region where the rear seat is disposed. The rear area of the rear floor panel (3) includes a double panel structure (14) having an upper wall and a lower wall (12). The rear area of the rear floor panel (3) extends further toward the rear side of the vehicle than the rear side frame (2). Each rear end part of the rear side frame (2) comprises an inclined supporting part (20) which inclines towards the front side of the vehicle towards the inner side of the width direction of the vehicle. The double panel structure (14) is coupled to the inclined support section (20) of each rear frame (2).

    本发明提供一种车体后部结构,可不导致车辆重量的增加而充分吸收输入至车体后部的冲击负荷。车体后部结构包括:左右一对后侧框架(2),大致沿车辆前后方向延伸;以及后地板面板(3),在配置后座椅的前部区域,结合一对后侧框架(2)。后地板面板(3)的后部区域包含具有上壁及下壁(12)的双层面板结构体(14)。后地板面板(3)的后部区域较后侧框架(2)更向车辆后方侧延伸。后侧框架(2)的各后端部包括向车宽方向内侧朝车辆前方侧倾斜的倾斜支撑部(20)。双层面板结构体(14)结合于各后侧框架(2)的倾斜支撑部(20)。
