PURPOSE:To aim at reduction in the load imposed on a wheel house, by connecting a suspension mounting outer rigger to space between a rear side member and a wheel house inner panel or the like, and forming a belt anchor mounting part in and around an out rigger joint of the panel. CONSTITUTION:A rear side member 1 as a section hat-form body skeletal member is connected to a floor panel (unillustrated herein) at an upper edge flange part 1a. And, a wheel house inner panel 2 constituting a wheel house part is fitted with a rear side flange part 3a of a sill inner panel 3 constituting a side sill, at the front side. In this case, a section hat-form out rigger 4 is connected to space between the rear side member 1 and a joint of the wheel house inner panel 2 and the sill inner panel 3. Then, a seat belt anchor mounting part 6 is made so as to be installed in and around a joint part of the out rigger 4 of the wheel house inner panel 2.
