To provide a side sill structure which has a small 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 hollow parts 103 aligned in a vehicle length direction inside the side sill main body 101. The energy-absorbing structure 102 has a base component 121 that is formed from a single blank plate 130. The base component 121 has: a first vertical plate part 132 that extends in the vehicle length direction on the outer side in a vehicle width direction relative to a plurality of through holes 131 aligned in the vehicle length direction and is joined to an inner surface of the outer wall 111; a plurality of horizontal plate parts 134 that extend in the vehicle width direction from the first vertical plate part 132 between adjacent through holes 131; and a plurality of flange bodies 135 that are respectively cut and raised upward from the plurality of horizontal plate parts 134. The plurality of horizontal plate parts 134 and the plurality of flange bodies 135 are aligned in the vehicle length direction.SELECTED DRAWING: Figure 3A
【課題】部品点数が少なく、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は、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中空部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、単体のブランク板130から形成されたベース部品121を有する。ベース部品121は、車長方向に並ぶ複数の貫通孔131に対して車幅方向外側で車長方向に延び、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から隣接する貫通穴131の間を車幅方向に延びる複数の横板部134と、複数の横板部134それぞれから上方へ切り起こされた複数のフランジ体135とを有し、複数の横板部134及び複数のフランジ体135は、車長方向に並べられている。【選択図】図3A
