To provide a vehicle body side part structure in which a lower part of a pillar has rigidity more excellent than before and which can more surely prevent torsion from occurring in a vehicle body during steering or due to upthrust from a road surface.SOLUTION: A vehicle body side part structure 10 comprises: a side sill 1 extending in a vehicle longitudinal direction; a center pillar 2 extending upward from the side sill 1 and constituting a closed cross-section by an inner member 22 and a stiffener member 21; and a widened part 2a formed at a lower part of the center pillar 2, and gradually widening in the vehicle longitudinal direction as going downward. The center pillar 2 comprises a first rigid foaming member 16 at an end part in the vehicle longitudinal direction in the closed cross-section C3 of the widened part 2a.SELECTED DRAWING: Figure 5
【課題】本発明は、従来よりもピラーの下部に優れた剛性を有し、操舵時や路面からの突き上げなどによって車体にねじれが発生することをより確実に防止す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、車両前後方向に延びるサイドシル1と、前記サイドシル1から上方に延びてインナ部材22とスティフナ部材21とで閉断面を構成するセンタピラー2と、前記センタピラー2の下部に形成されて下方に向かうほど車両前後方向に徐々に幅広となる拡幅部2aと、を備える車体側部構造10において、前記センタピラー2は、前記拡幅部2aの閉断面C3内の車両前後方向の端部に第1剛性発泡部材16を備えることを特徴とする。【選択図】図5
