PROBLEM TO BE SOLVED: To simplify structure, reduce the number of components, and facilitate manufacturing of the structure. SOLUTION: Rear side frames 5, 5 arranged on both left/right sides of a car body rear part are divided into a front part frame 11 and a rear part frame 12. Components constituting a rear suspension are mounted to the front part frame 11, and a crash zone A is provided for the rear part frame 11 for absorbing an impact load at the time of a rear face collision. As the front part frame 11 holds the rear suspension, fewer sites of the rear part frame 12 need to be reinforced even though the plate thickness of the rear part frame 12 is set with the axial collapse of the crash zone A as a reference, while the plate thickness of the front part frame 11 can be set with durability against a load of the rear suspension, etc., as a reference. As a result, the number of reinforcements can be reduced, which reduces the number of the components. COPYRIGHT: (C)2005,JPO&NCIPI
