To provide a vehicle body side part structure that can generate reaction force at an initial time of collision more sufficiently and surely than before.SOLUTION: A vehicle body side part structure 10 comprises: a center pillar 2 forming a closed cross-section C3 by an inner member 22 and a stiffener member 23 arranged outside in a vehicle width direction of the inner member 22; and a plurality of rigid foaming members 17 arranged at respective end parts in a vehicle longitudinal direction in the closed cross section C3 of the center pillar 2. The rigid foaming members 17 are arranged along an outer wall outside in a vehicle width direction of the stiffener member 21 and along a side wall extended from an edge in the vehicle longitudinal direction of the outer wall to inside in the vehicle width direction, where end parts inside in the vehicle width direction of the rigid foaming members 17 are in contact with the inner member 22.SELECTED DRAWING: Figure 5

    【課題】本発明は、従来と比べて衝突初期における反力を十分にかつ確実に発生させることができる車体側部構造を提供する。【解決手段】本発明は、インナ部材22と、前記インナ部材22の車幅方向の外側に配置されるスティフナ部材23とで閉断面C3を形成するセンタピラー2と、前記センタピラー2の前記閉断面C3内における車両前後方向のそれぞれの端部に配置される複数の剛性発泡部材17と、を備える車体側部構造10において、前記剛性発泡部材17は、前記スティフナ部材21における車幅方向の外側の外壁と、この外壁の車両前後方向の端縁から車幅方向の内側に延設される側壁と、に沿って配置され、剛性発泡部材17の車幅方向の内側の端部が、インナ部材22に接していることを特徴とする。【選択図】図5
