To increase an absorption amount of impact energy at the time of a side collision and suppress deformation of a vehicle body at the center in a vehicle width direction.SOLUTION: A reinforcement member 40 attached to the inside of a fourth cross member 30 connecting left and right rockers 11L, 11R in a vehicle width direction includes: a center portion 41 disposed at the center in the vehicle width direction at which a battery back 60 is mounted; a left end portion 43L; and a left connection portion 42L. The upper surface of the left end portion 43L is offset upward from the upper surface of the center portion 41 in a height direction. The left connection portion 42L is inclined upward from the center portion 41 toward the left end portion 43L. The center portion 41 and the left connection portion 42L constitute a high proof strength portion 48 with high rigidity. The left end portion 43L constitutes a left low proof strength portion 49L with rigidity lower than the high proof strength portion 48.SELECTED DRAWING: Figure 2

    【課題】側突の際の衝撃エネルギの吸収量を増加させるとともに、車両幅方向中央の車体の変形を抑制する。【解決手段】左右のロッカ11L,11Rを車両幅方向に接続する第4クロスメンバ30の内部に取り付けられる補強部材40であって、電池パック60が搭載される車両幅方向中央に配置される中央部41と、左端部43Lと、左接続部42Lとを備え、左端部43Lの上面は、中央部41の上面よりも高さ方向上方にオフセットされており、左接続部42Lは、中央部41から左端部43Lに向かって斜め上方向に傾斜しており、中央部41と左接続部42Lとは剛性の高い高耐力部48を構成し、左端部43Lは高耐力部48よりも剛性が低い左低耐力部49Lを構成する。【選択図】図2
