To provide a side sill reinforcement structure for vehicles characterized in that an absorption quantity of impact energy is upgraded.SOLUTION: A reinforcement member 40 that reinforces a side sill 20 includes plural closed section parts 51 to 54 that are concatenated in a vehicle width direction. The plural closed section parts 51 to 54 are defined with a pair of webs 41 and 42 that are opposed to each other in a vertical direction, and plural side walls 47a to 47e that are arranged in the vehicle width direction with a space between adjoining ones and connect the pair of webs 41 and 42. Thicknesses tw2 and tw3 of webs 44A and 44B of intermediate closed section parts 59A and 59B are larger than a thickness tw1 of a web 43A of an outermost closed section part 58A, and are larger than a thickness tw4 of a web 43B of an innermost closed section part 58B.SELECTED DRAWING: Figure 3
【課題】 衝撃エネルギーの吸収量が向上した車両用サイドシル補強構造を提供する。【解決手段】 サイドシル20を補強する補強部材40が、車幅方向に連なる複数の閉断面部51~54を有する。複数の閉断面部51~54は、上下方向に対向配置された一対のウェブ41,42と、車幅方向に間隔をあけて配置されて一対のウェブ41,42同士を接続する複数の側壁47a~47eとによって画定される。中間閉断面部59A,59Bのウェブ44A,44Bの厚さtw2,tw3が、最外閉断面部58Aのウェブ43Aの厚さtw1よりも厚く、且つ最内閉断面部58Bのウェブ43Bの厚さtw4よりも厚い。【選択図】図3
