To effectively improve resistance of a rear side frame against load input due to collision of a vehicle with simple configuration.SOLUTION: A vehicle body rear part structure comprises: a rear side frame (10) extending in a cross direction of a vehicle body (1) on a vehicle width direction outer side in a floor part (2) at a rear part of the vehicle body (1); and a foil house (50) which is located outside the rear side frame (10) in a vehicle width direction. At least a part of a wall part (12) on the vehicle width direction outer side in the rear side frame (10) is formed by the foil house (50), and comprises a partition member (80) installed in a cross section of the rear side frame (10). The partition member (80) has one end in the vehicle width direction that is joined to the outside wall part (12) formed by the foil house (50) and extends from the outside wall part (12) to a front side of the vehicle body (1) and an inner side in the vehicle width direction, and has the other end in the vehicle width direction that is joined to a wall part (13) inside the rear side frame (10).SELECTED DRAWING: Figure 1

    【課題】簡単な構成で、車両の衝突による荷重の入力に対するリアサイドフレームの耐性を効果的に向上させる。【解決手段】車体(1)の後部のフロア部(2)における車幅方向の外側で車体(1)の前後方向に延在するリアサイドフレーム(10)と、車幅方向におけるリアサイドフレーム(10)の外側に配置されたホイルハウス(50)と、を備え、リアサイドフレーム(10)における車幅方向の外側の壁部(12)の少なくとも一部は、ホイルハウス(50)で形成され、リアサイドフレーム(10)の断面内に設置した仕切部材(80)を備え、仕切部材(80)は、車幅方向の一方の端部がホイルハウス(50)で形成された外側の壁部(12)に接合され、外側の壁部(12)から車体(1)の前方側かつ車幅方向の内側に延び、車幅方向の他方の端部がリアサイドフレーム(10)の内側の壁部(13)に接合される。【選択図】図1
