To provide a vehicle rear part structure that can appropriately prevent or inhibit a defect such that an auxiliary machine mounted at a vehicle rear part is damaged at the time of a rear collision of a vehicle.SOLUTION: A vehicle rear part structure A includes a standing attachment part 40 attached to a lower back 7 and a substantially L-shaped reinforcement member 4 having a front-to-rear extended part 41 overlapped via a rear floor part 2 with a rear side member 3 to be connected thereto. The rear side member 3 is sectioned into a first region S1 overlapped with the front-to-rear extended part 41 to be connected thereto, a second region S2 located adjacently to the first region on the vehicle front side thereof, and a third region S3 located adjacently to the second region on the vehicle front side thereof. In addition, the first and third regions S1, S3 are configured as regions with the rigidity higher than that of the second region S2, and a front end P of the first region S1 is located on the vehicle front side of an auxiliary machine 1.SELECTED DRAWING: Figure 1

    【課題】車両後部に搭載された補機が車両の後突時に損傷する不具合を適切に防止または抑制し得る車両後部構造を提供する。【解決手段】車両後部構造Aは、ロアバック7に取付けられる起立状取付け部40、およびリヤフロア部2を挟んでリヤサイドメンバ3と重ねられて接合される前後方向延設部41を有する略L字状の補強部材4を備えており、リヤサイドメンバ3は、前後方向延設部41が重ねられて接合された第1の領域S1、その車両前方側に隣接した第2の領域S2、さらにその車両前方側に隣接した第3の領域S3に区分され、かつ第1および第3の領域S1,S3は、第2の領域S2よりも高強度領域とされ、第1の領域S1の前端Pは、補機1よりも車両前方側に位置している。【選択図】 図1
