To provide a vehicle body rear part structure capable of transmitting an impact load input from the vehicle rear side of a rear side frame to a side sill efficiently.SOLUTION: A vehicle body rear part includes a side sill 1, a rear wheel house 2, a rear side frame 3, and a closing plate 10. An outer curve part 40o and an inner curve part 40i are provided at an area close to a front part of the rear wheel house 2 of the rear side frame 3. The closing plate 10 is provided with: an outer ridge line 50o linearly extending from a position almost immediately above an area close to a rear end part of the outer curve part 40o of the rear side frame 3 to the vehicle front; and an inner ridge line 50i which extends curving to the vehicle front side roughly along the inner curve part 40i at a position almost immediately above the inner curve part 40i of the rear side frame 3. The outer ridge line 50o and the inner ridge line 50i join at an inner area as seen in a vehicle width direction of a coupling part between the rear side frame 3 and the side sill 1.SELECTED DRAWING: Figure 1 【課題】リヤサイドフレームの車両後方側から入力された衝撃荷重をサイドシルに効率良く伝達することができる車体後部構造を提供する。【解決手段】車体後部は、サイドシル１、リヤホイールハウス２、リヤサイドフレーム３、閉塞プレート１０を備えている。リヤサイドフレーム３のリヤホイールハウス２の前部に近接する領域には外湾曲部４０ｏと内湾曲部４０ｉが設けられる。閉塞プレート１０には、リヤサイドフレーム３の外湾曲部４０ｏの後端部の近傍のほぼ直上位置から車両前方に直線状に延びる外側稜線５０ｏと、リヤサイドフレーム３の内湾曲部４０ｉのほぼ直上位置において、内湾曲部４０ｉに略沿って車両前方側に湾曲して延びる内側稜線５０ｉが設けられる。外側稜線５０ｏと内側稜線５０ｉはリヤサイドフレーム３とサイドシル１の結合部の車幅方向内側領域で合流する。【選択図】図１
