Summary: | To provide a vehicle body rear part structure which is improved in collision-resistant performance and achieves weight saving.SOLUTION: A vehicle body rear part structure 1 includes: a rear frame 30 extended in a vehicle body longitudinal direction on a vehicle width direction end side of a floor panel 2; a rear wheel house 70 extended upward from a vehicle width direction outer part of the rear frame 30; a rear cross member 60 extended in a vehicle width direction on the floor panel 2; a wheel house reinforcement member extended in a vertical direction along the rear wheel house 70; and an upper stiffener 4 covering an aperture of the rear frame 30. The upper stiffener 4 includes a front part stiffener 40 and a rear part stiffener 50. A lower part of the wheel house reinforcement member is coupled to the upper stiffener 4 and the rear cross member 60. A coupling part of the front part stiffener 40 and the rear part stiffener 50 is offset in the longitudinal direction with the upper stiffener 4 and the wheel house reinforcement member.SELECTED DRAWING: Figure 1
【課題】 耐衝突性能を向上するとともに軽量化を実現することが可能な車体後部構造を提供する。【解決手段】 車体後部構造1は、フロアパネル2の車幅方向端部側において車体前後方向に延設されるリアフレーム30と、リアフレーム30の車幅方向外部から上方に延設されるリアホイルハウス70と、フロアパネル2上で車幅方向に延設されるリアクロスメンバ60と、リアホイルハウス70に沿って上下方向に延設されるホイルハウス補強部材と、リアフレーム30の開口部を覆うアッパスティフナ4と、を備え、アッパスティフナ4は、前部スティフナ40及び後部スティフナ50を備え、ホイルハウス補強部材の下部は、アッパスティフナ4及びリアクロスメンバ60に結合されており、前部スティフナ40及び後部スティフナ50の結合部は、アッパスティフナ4及びホイルハウス補強部材の結合部と前後方向にオフセットしている。【選択図】図1 |
