Abstract

In a vehicle rear structure that is one example of a vehicle body structure, a rear suspension tower (16) that is made of aluminum die-cast and a wheel house outer (20) that is made of metal material having higher fatigue strength than the rear suspension tower (16), are joined together via an extension panel (22) that is made of metal material having higher fatigue strength than the rear suspension tower (16). Further, a step portion (36) is formed between an inner peripheral portion (30) and an outer peripheral portion (32) of the extension panel (22).

Description

technical field [0001] The present invention relates to vehicle body structures. Background technique [0002] Japanese Patent Application Publication No. 2010-18087 (JP 2010-18087A) discloses a rear body part of a vehicle. In short, the vehicle body side wall at the rear of the vehicle body is formed of a side quarter inner panel forming a compartment inner wall surface and a side quarter outer panel forming a vehicle body outer side wall surface. Furthermore, the lower portion of the side panel inner panel is a wheel arch portion curved toward the vehicle width direction outer side. Also, in a vehicle side view, a reinforcement member extending in the vehicle up-down direction is arranged in the center portion of the wheel arch portion, and is formed by the reinforcement member and the vertical wall portion of the side panel inner panel and the wheel arch portion. Closed section. Furthermore, at the middle portion in the height direction of the reinforcement, a hat-shap...
