To increase an absorption quantity of impact energy in a side sill reinforcement structure for a vehicle.SOLUTION: A side sill reinforcement structure for vehicles includes: a side sill 20 extending in a vehicle fore-and-aft direction in a lateral part of a vehicle; and a reinforcement member 40 that reinforces the side sill 20. The reinforcement member 40 has plural closed cross-sectional parts 40a juxtaposed in a vehicle width direction on a cross section vertical to the vehicle fore-and-aft direction. The closed cross-sectional parts 40a include a first closed cross-sectional part 41 disposed outermost in the vehicle width direction. The first closed cross-sectional part 41 includes a first upper wall 41a and first lower wall 41b opposed to each other and separated from each other in a vehicle vertical direction, and a first lateral wall 41c connecting outside edges in the vehicle width direction of the first upper wall 41a and first lower wall 41b respectively. A thickness of the first lateral wall 41c is larger than that of the first upper wall 41a or outermost lower wall 41b.SELECTED DRAWING: Figure 2

    【課題】車両用サイドシル補強構造において、衝撃エネルギーの吸収量を向上させる。【解決手段】車両用サイドシル補強構造は、車両の側部において車両前後方向に延びるサイドシル20と、サイドシル20を補強する補強部材40とを備えている。補強部材40は、車両前後方向に垂直な断面において車幅方向に連なる複数の閉断面部40aを有している。複数の閉断面部40aは、車幅方向の最も外側に配置された第1閉断面部41を含んでいる。第1閉断面部41は、車両上下方向に互いに離れて対向配置された第1上壁41aおよび第1下壁41bと、第1上壁41aおよび第1下壁41bの車幅方向の外側端部を接続する第1側壁41cとを含んでいる。第1側壁41cの厚みは、第1上壁41aまたは最外下壁41bの厚みよりも大きい。【選択図】図2
