To improve rigidity and strength in a region between a front cross member and a rear cross member.SOLUTION: A rear subframe construction comprises: a pair of left and right vertical members 18, 18 which extend in a longitudinal vehicle direction; and a front cross member 20 and a rear cross member 22 which extend along a vehicle width direction between the vertical members, and are spaced at a prescribed interval along the longitudinal vehicle direction. Each vertical member 18 has a protrusion part 26 which bulges in a downward direction crossing a longitudinal direction of the vertical member 18 in a region between the front cross member 20 and the rear cross member 22. A dimension (H2) of the protrusion part 26 in the vehicle width direction is smaller than a dimension (H1) of the vertical member 18 in the vehicle width direction (H1>H2).SELECTED DRAWING: Figure 4

    【課題】前クロスメンバと後クロスメンバとの間の領域における剛性・強度を向上させること。【解決手段】車両前後方向に延びる左右一対の縦メンバ18、18と、縦メンバの間で車幅方向に沿って延びると共に、車両前後方向に沿って互いに所定間隔離間して配置される前クロスメンバ20及び後クロスメンバ22とを備え、各縦メンバ18は、前クロスメンバ20と後クロスメンバ22との間の領域において、縦メンバ18の長手方向に対して交差する下方向に向かって膨出する凸部26を有し、この凸部26の車幅方向の寸法(H2)は、縦メンバ18の車幅方向の寸法(H1)よりも小さくなっている(H1>H2)。【選択図】図4
