REAR VEHICLE BODY STRUCTURE OF VEHICLE

To provide a rear vehicle body structure of a vehicle 1, which can inhibit upsizing of a nut member 10 and which can secure support stiffness of the nut member 10.SOLUTION: A rear vehicle body structure of a vehicle 1 comprises: a pair of right and left rear side frames 2; a rear bumper beam 5 that assumes an opened cross-sectional shape; a pair of right and left set plates 4 that is joined to the rear bumper beam 5; a nut member 10 to which a hook member 9 is screwed; and a support member 11 for supporting the nut member 10 between the set plates 4 and the rear bumper beam 5. In the support member 11, an intermediate wall part 111, which faces a rear wall part 51 of the rear bumper beam 5 and the set plate 4 at intervals in a longitudinal direction of the vehicle and to which the vicinity of a front end of the nut member 10 is joined, a first attachment piece part for attaching the intermediate wall part 111 to the set plate 4, and a second attachment piece part for attaching the intermediate wall part 111 to the rear bumper beam 5 are integrally formed.SELECTED DRAWING: Figure 3 【課題】ナット部材１０の大型化を抑制できるとともに、ナット部材１０の支持剛性を確保できる車両１の後部車体構造を提供することを目的とする。【解決手段】車両１の後部車体構造であって、左右一対のリヤサイドフレーム２と、開断面形状のリヤバンパビーム５と、リヤバンパビーム５に接合される左右一対のセットプレート４と、フック部材９が螺合するナット部材１０と、セットプレート４とリヤバンパビーム５との間でナット部材１０を支持する支持部材１１とを備え、支持部材１１は、リヤバンパビーム５の後壁部５１、及びセットプレート４に対して車両前後方向に間隔を隔てて対面するとともに、ナット部材１０の前端近傍が接合された中間壁部１１１と、中間壁部１１１をセットプレート４に取付ける第１取付片部と、中間壁部１１１をリヤバンパビーム５に取付ける第２取付片部とが一体形成されたことを特徴とする。【選択図】図３
