To provide a side sill which can effectively absorb the impact energy at the side face collision with a light-weight and low-cost structure.SOLUTION: A side sill 2 includes a first lateral cross section part 10 and a second lateral cross section part 20 that are connected to each other. The second lateral cross section part 20 is located on the inner side in the vehicle width direction of the first lateral cross section part 10. The first lateral cross section part 10 has a vertically long shape including first outer walls 11, 12, 13, 14 and first internal lateral walls 15, 16 forming the closed-cross section. The second lateral cross section part 20 has second outer walls 21, 22, 23, 24 and a second internal vertical wall 25 forming the closed-cross section. In the vehicle vertical direction, the first outer walls 11-14 have a larger dimension than those of the second outer walls 21-24, the upper ends of the first outer walls 11-14 are located at the higher positions than those of the upper ends of the second outer walls 21-24.SELECTED DRAWING: Figure 1 【課題】軽量かつ低コストの構造で、側面衝突時の衝撃エネルギーを有効に吸収することが可能なサイドシルを提供する。【解決手段】サイドシル２は、互いにつながる第１横断面部１０と第２横断面部２０とを備え、第２横断面部２０は第１横断面部１０の車幅方向内側に位置する。第１横断面部１０は、閉断面を形成する第１外壁１１，１２，１３，１４と第１内部横壁１５，１６とを含む縦長の形状を有する。第２横断面部２０は、閉断面を形成する第２外壁２１，２２，２３，２４と第２内部縦壁２５とを含む。車両上下方向について第１外壁１１〜１４は第２外壁２１〜２４よりも大きな寸法を有し、第１外壁１１〜１４の上端は第２外壁２１〜２４の上端よりも高い位置にある。【選択図】図１
