PROBLEM TO BE SOLVED: To improve a tire support strength and NVH performances of a spare tire pan while suppressing an increase in weight.SOLUTION: A rear body structure of a vehicle comprises a spare tire pan 2 recessed downward with a cross member 24 for reinforcing the spare tire pan 2. The rear body structure of a vehicle is further provided with: a longitudinal member 26 extending to a rear side of the cross member 24 on a lower surface of the spare tire pan 2; and a keyhole-shaped bead 31 disposed at a position overlapping a front part of the longitudinal member 26 in a plan view, and showing a keyhole-like shape in a plan view. Optionally, a tire support bracket 41 is connected to a front part of the keyhole-shaped bead 31.SELECTED DRAWING: Figure 1 【課題】スペアタイヤパンのタイヤ支持強度とＮＶＨ性能を重量の増加を抑えながら向上させること。【解決手段】下方に凹んだスペアタイヤパン２を備え、該スペアタイヤパン２を補強するクロスメンバ２４が設けられ、スペアタイヤパン２下面においてクロスメンバ２４の後方に延びる縦メンバ２６を設け、該縦メンバ２６の前部と平面視で重なる位置に、平面視前方後円状をした前方後円状ビード３１を設けた構成とし、必要に応じてタイヤ支持ブラケット４１を前方後円状ビード３１の前方部位に結合した。【選択図】図１
