The present invention addresses the problem of improving the absorption efficiency of a side collision load by suppressing the moment acting on a side sill when the side collision load is input to a vehicle. The side sill structure (10) is provided with a side sill (12a) which extends in the front-rear direction of the vehicle on the outer side of a floor panel (11) in the width direction of the vehicle and which forms a closed cross-section by combining a side sill inner member (2a1) on the inner side of the vehicle and a side sill outer member (2a2) on the outer side of the vehicle. The side sill (12a) has, in a closed cross-section, a plurality of partition members (21), and a reinforcement (22) that connects the plurality of partition members (21) in the longitudinal direction of the side sill (12a). The stiffener (22) is configured to be disposed along a corner portion (1c) formed by an inner side wall (1b) and an upper wall (1a) of the side sill inner member (2a1) on the vehicle inner side.
本发明的课题为,当向车辆输入侧碰撞荷载时抑制对下纵梁作用的力矩而提高侧碰撞荷载的吸收效率。下纵梁构造(10)具有在地板面板(11)的车宽方向外侧沿车辆前后方向延伸、并通过车内侧的下纵梁内构件(2a1)与车外侧的下纵梁外构件(2a2)的组合而构成闭合截面的下纵梁(12a),下纵梁(12a)在闭合截面内具有多个分隔部件(21)、和沿着下纵梁(12a)的长边方向将该多个分隔部件(21)连结的加强件(22)。加强件(22)构成为,沿着由下纵梁内构件(2a1)的车内侧的内侧壁(1b)和上壁(1a)形成的角落部(1c)配设。
