To provide a vehicle body rear part structure capable of obtaining desired rigidity while suppressing increase in weight.SOLUTION: A vehicle body rear part structure includes a floor panel 2, side frames 3 and 3 that are arranged outside in a vehicle width direction of the floor panel 2 and extend in a longitudinal direction of the vehicle body, a cross member 4 that is bridged between the side frames 3 and 3 so as to saddle over the floor panel 2 and suspends a power storage device 5 above the floor panel 2, a third row seat 6 that is arranged at a position overlapping the power storage device 5 in top view, and a seat support part 7 supporting the third row seat 6. The cross member 4 has a fastening part 10 fastened to the side frames 3 and 3, and an intermediate part 11 offset to either side of the longitudinal direction of the vehicle body rather than the fastening part 10. The seat support part 7 is fixed to the side frame 3 in a range that the intermediate part 11 is offset in a vehicle body rear direction with respect to the fastening part 10.SELECTED DRAWING: Figure 1

    【課題】重量の増加を抑制しつつ所望の剛性を得られる車体後部構造を提供する。【解決手段】フロアパネル2と、フロアパネル2の車幅方向外側に配置され、車体前後方向に延設されるサイドフレーム3,3と、フロアパネル2を跨いでサイドフレーム3,3間に架け渡されて、蓄電装置5をフロアパネル2の上方に吊下げるクロスメンバ4と、上面視にて蓄電装置5と重なる位置に配置される三列目シート6と、三列目シート6を支持するシート支持部7とを備えている。クロスメンバ4は、サイドフレーム3,3に締結される締結部10と、締結部10よりも車体前後方向の何れかにオフセットされる中間部11とを有している。シート支持部7は、締結部10に対して中間部11が車体後方向にオフセットされた範囲においてサイドフレーム3に固定されている。【選択図】図1
