In an automobile body structure, a rear end of a side sill (13) and a front end of a rear side frame (14) are connected by a kick-up portion (41) curving from a front lower part to a rear upper part, and an iron cast joint (42) including a suspension arm support portion (42a) supporting a suspension arm (43) and a cross member support portion (42b) supporting an end portion of a middle cross member (19) extending in a vehicle width direction is connected to the kick-up portion (41). In this way, the kick-up portion (42) is suppressed from being bending-deformed such that a rear end of the rear side frame (14) is raised by collision load from a rear collision. Not only can the collision load be efficiently absorbed by crushing the rear side frame (14) in an axis (L) direction, but also the torsional rigidity of the vehicle body can be increased by strong connection of the middle cross member (19) to the kick-up portion (41). |
