PROBLEM TO BE SOLVED: To provide a rear vehicle body structure of a vehicle which makes relative strength difference in a middle of a rear side member forming a rear vehicle body to induce deformation of the rear side member from an area, in which the strength of the rear side member is low, in a direction that avoids a fuel tank when an impact load is applied from a vehicle body rear part to prevent damage of the fuel tank etc.SOLUTION: A rear vehicle body structure of a vehicle includes: a pair of left and right rear side members 5; a cross member 6 connecting the rear side members 5; a fuel tank 7 disposed at a front side of the cross member 6; a vehicle body mounted component disposed at a rear side of the cross member 6; and reinforcing members 9 disposed on the pair of left and right rear side members 5 so as to include a front end to a rear end of a body part of the vehicle body mounted component. A front end of each reinforcing member 9 is disposed so as to be located at a rear side of a rear end position of a connection part between the rear side member 5 and the cross member 6.SELECTED DRAWING: Figure 1 【課題】 後部車体を構成するリヤサイドメンバの途中に相対的な強度差を設け、車体後部から衝撃荷重が加わった際にリヤサイドメンバの強度の低い個所から燃料タンクを避ける方向にリヤサイドメンバの変形を誘発し、燃料タンク等に損傷が及ぶことを防止する自動車の後部車体構造を提供する。【解決手段】 左右一対のリヤサイドメンバ５と、これらリヤサイドメンバ５相互間を連結したクロスメンバ６と、このクロスメンバ６の前方に配設された燃料タンク７と、前記クロスメンバ６の後方に配設された車体搭載部品と、この車体搭載部品の本体部の前端から後端までを含むように前記左右一対のリヤサイドメンバ５に配設された補強部材９とを備え、該補強部材９の前端が、前記リヤサイドメンバ５と前記クロスメンバ６の連結部の後端位置よりも後方に来るように配置したことにある。【選択図】 図１
