To reduce moment applied to a side sill when a side collision load is input to a vehicle and thereby improve absorption efficiency of the side collision load.SOLUTION: A side sill structure 10 includes a side sill 12a extending in a vehicle front-back direction on an outer side of a floor panel 11 in a vehicle width direction and forms a closed cross-section with a combination of a sill inner 2a1 on a vehicle inner side and a sill outer 2a2 on a vehicle outer side. The side sill 12a includes within the closed cross-section a plurality of partition members 21 and a stiffener 22 connecting the plurality of partition members 21 along a longitudinal direction of the side sill 12a. The stiffener 22 is disposed along a corner portion 1c formed by an inner wall 1b and an upper wall 1a on a vehicle inner side of the sill inner 2a1.SELECTED DRAWING: Figure 2

    【課題】車両への側突荷重入力時に、サイドシルに掛かるモーメントを抑制して側突荷重の吸収効率を向上させること。【解決手段】サイドシル構造10は、フロアパネル11の車幅方向外側で車両前後方向に延在し、車内側のシルインナ2a1と車外側のシルアウタ2a2との組み合わせで閉断面を成すサイドシル12aを備え、サイドシル12aは、閉断面内に複数の仕切部材21と、サイドシル12aの長手方向に沿って複数の仕切部材21を連結するスティフナ22と、を備える。スティフナ22は、シルインナ2a1の車内側の内側壁1bと上壁1aとで形成される角部1cに沿って配設される構成とする。【選択図】図2
