To provide a vehicle rear section structure capable of appropriately preventing or suppressing a failure of an electricity storage device loaded on the rear section of a vehicle like a breakdown when the rear section of the vehicle collides.SOLUTION: A vehicle rear section structure A includes: an electricity storage device 3 fastened on a bottom wall portion 22 of a recess 20 provided in a floor portion 2 in a vehicle compartment 1 at the rear section of a vehicle; and reinforcements 5A and 5B which are joined to the lower surface side of the bottom wall portion 22, extend toward the front section of the vehicle from the rear portion of the bottom wall portion 22, and have respective front portions joined to a floor cross member 8. This vehicle rear section structure further has rigid-break points RP which are provided at, in the respective reinforcements 5A and 5B, respective portions matching a rear end portion Sa of an attachment region S of the electricity storage device 3 in the vehicle back-and-forth direction or respective portions at the vehicle rear side relative to the foregoing portions, become origins of bending and deformation when a load equal to or greater than a predetermined magnitude is input from the vehicle rear section, and enable the electricity storage device 3 to rotate backward and downward.SELECTED DRAWING: Figure 1

    【課題】車両後部に搭載された蓄電装置が車両の後突時に破損するなどの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】車両後部の車室1内のフロア部2に設けられた凹部20の底壁部22上に固定された蓄電装置3と、底壁部22の下面側に接合され、かつ底壁部22の後部から車両前方側に延びて前部がフロアクロスメンバ8に接合されたリインフォース5A,5Bと、を備えている、車両後部構造Aであって、リインフォース5A,5Bのうち、車両前後方向において、蓄電装置3の取付け領域Sの後端部Saに一致する部位、またはこの部位に接近した車両後方寄りの部位に設けられ、かつ車両後方側からの所定以上の荷重入力があったときに屈曲変形の起点となり、蓄電装置3が後下がり状に回転することを可能とする剛性断点RPを、さらに備えている。【選択図】 図1
