PROBLEM TO BE SOLVED: To provide a side sill structure which enables improvements of NVH performance and collision performance which inhibiting increase in the number of components and plate thickness.SOLUTION: A side sill structure 100 extends from an area below a front pillar 106 of a vehicle 102 to the vehicle rear side. The side sill structure 100 includes: a side sill inner 122 having no front end surface at the vehicle front side and including a first opening part 138 formed therein; a side sill outer 124 joined to the vehicle outer side of the side sill inner 122 along the side sill inner 122, forming a closed cross section 172 with the side sill inner 122, and having no front end surface at the vehicle front side, the side sill outer 124 including a second opening part 152 formed therein; an extension member 136 having a vertical wall part 140 which closes the first opening part 138 of the side sill inner 122; and a cover member 150 having a second vertical wall part 156 which closes the second opening part 152 of the side sill outer 124 and connected to the extension member 136 from the vehicle outer side.SELECTED DRAWING: Figure 7

    【課題】部品点数の増加および板厚の増大を抑えつつ、NVH性能および衝突性能を向上可能なサイドシル構造を提供する。【解決手段】サイドシル構造100は、車両102のフロントピラー106の下方から車両後方に延びている。サイドシル構造100は、車両前側の前端面を有せず第1開口部138が形成されているサイドシルインナ122と、サイドシルインナ122に沿ってその車外側に接合されサイドシルインナ122との間に閉断面172を形成し車両前側の前端面を有せず第2開口部152が形成されているサイドシルアウタ124と、サイドシルインナ122の第1開口部138を塞ぐ縦壁部140を有するエクステンション部材136と、サイドシルアウタ124の第2開口部152を塞ぐ第2縦壁部156を有しエクステンション部材136に車外側から接続されるカバー部材150とを備える。【選択図】図7
