To provide a side sill structure which achieves reduction of the weight of a vehicle body by reduction of the number of components and is excellent in impact absorption performance during a side collision.SOLUTION: A side sill structure 100 comprises: a side sill main body 101 having an outer wall 111 and an inner wall 112; and an energy-absorbing structure 102 that forms a plurality of cylindrical structures 103 aligned in a vehicle length direction inside the side sill main body 101. The energy-absorbing structural body 102 has a base component 121 formed from a single blank plate 130, and a plurality of reinforcing components 125 arranged at intervals in the vehicle length direction. The base component 121 has a first vertical plate part 132 that extends in the vehicle length direction and is joined to an inner surface of the outer wall 111, and a plurality of holding bodies 135 provided at the first vertical plate part 132. The reinforcing components 125 are held by the holding bodies 135, extend in a vehicle width direction, and form a closed cross-section when viewed from the vehicle width direction. Both ends of each of the reinforcing components 125 in the vehicle width direction are respectively located close to inner surfaces of the outer wall 111 and the inner wall 112.SELECTED DRAWING: Figure 2

    【課題】部品点数削減により車体軽量化を実現し、且つ側突時の衝撃吸収性に優れたサイドシル構造を提供する。【解決手段】サイドシル構造100が、外側壁111及び内側壁112を有するサイドシル本体101と、サイドシル本体101の内部で車長方向に並ぶ複数の筒構造103を形成するエネルギー吸収構造体102とを備える。エネルギー吸収構造体102は、単一のブランク板130から形成されたベース部品121と、車長方向に間隔をあけて配置される複数の補強部品125とを有する。ベース部品121は、車長方向に延びて外側壁111の内面に接合される第1縦板部132と、第1縦板部132に設けられた複数の保持体135とを有する。補強部品125は、保持体135に保持されて車幅方向に延び、車幅方向から見て閉断面を形成する。補強部品125の車幅方向の両端部は、外側壁111及び内側壁112それぞれの内面に近接されている。【選択図】図2
