PROBLEM TO BE SOLVED: To improve cabin protection performance against a side collision while improving productivity by a simple constitution, related to a vehicle body side face structure.SOLUTION: In a vehicle body side face structure in which a side sill 9 of a vehicle and a pillar base end part 8 are connected to each other, a cylinder part 6 arranged in a vehicle fore-and-aft direction and having a closed cross section shape, and a flange part 7 extending upward from the cylinder part 6 and arranged while facing a vehicle width direction are arranged at the side sill 9. A side face part 8a, an end face part 8b and a step part 8c are arranged at the pillar base end part 8. The side face part 8a is formed into a splayed shape in a side face view, and fixed to a side face 6c of the cylinder part 6. The end face part 8b is extended to the vehicle width direction from an end side of the side face part 8a in the vehicle width direction, and fixed to the flange part 7. Furthermore, a lower end side of the end face part 8b is formed into a narrowing hem shape. The step part 8c is formed into a stepped hill shape having steps in a plate thickness direction, and arranged at the lower end part of the end face part 8b.
【課題】車体側面構造に関し、簡素な構成で生産性を向上させつつ、側突に対する車室保護性能を改善する。【解決手段】車両のサイドシル9とピラー基端部8とが結合される車体側面構造において、車両前後方向に配置される閉断面形状の筒部6と、筒部6から上方へ延設され車幅方向に面して配置されるフランジ部7と、をサイドシル9に設ける。また、ピラー基端部8には、側面部8a,端面部8b及びステップ部8cを設ける。側面部8aは、側面視で裾広がり形状に形成し、筒部6の側面6cに固定する。端面部8bは、側面部8aの車両前後方向の端辺から車幅方向に延設してフランジ部7に固定する。また、端面部8bの下端辺は、側面視で裾狭まり形状に形成する。ステップ部8cは、板厚方向に段差を持つ段丘状に形成し、端面部8bの下端部に配置する。【選択図】図3
