This vehicle body side structure (1) is provided with: a collision energy absorbing member (11) provided in a convex shape toward the outside in the vehicle width direction on the outer peripheral side in the vehicle width direction of a battery pack (5); and a recessed portion (13) which is formed in the side sill (3) in a recessed shape so as to secure a space between the collision energy absorbing member (11) and the side sill (3), and which delays the timing of contact between the side sill (3) and the collision energy absorbing member (11) when a collision load is input to the side surface of the side sill (3). Thus, a collision load input to the side sill (3) is transmitted to the floor cross member (7) before the side sill (3) is in contact with the collision energy absorbing member (11), and after the side sill (3) is in contact with the collision energy absorbing member (11), the collision energy absorbing member (11) absorbs collision energy, thereby reducing the load transmitted to the battery pack (5).

    本发明的车身侧部构造(1)具备:碰撞能量吸收部件(11),其在电池包(5)的车宽方向外周侧朝向车宽方向车外侧设置为凸形状;和凹形状部(13),其以在碰撞能量吸收部件(11)与下纵梁(3)之间确保空间的方式呈凹形状形成于下纵梁(3),在碰撞载荷输入到下纵梁(3)的侧面时,使下纵梁(3)与碰撞能量吸收部件(11)接触的时机延迟,由此在下纵梁(3)与碰撞能量吸收部件(11)接触之前使输入到下纵梁(3)的碰撞载荷传递至地板横梁(7),在下纵梁(3)与碰撞能量吸收部件(11)接触后,使碰撞能量吸收部件(11)吸收碰撞能量,由此使传递到电池包(5)的载荷降低。
