PROBLEM TO BE SOLVED: To improve strength against plastic deformation of a pillar structure of a vehicle body.SOLUTION: A pillar structure of a vehicle body of the present invention comprises: a hat-shaped outer member having a channel part in its cross section; an inner member installed between a pair of flange parts of the outer member; and a reinforcement member interposed between both flange parts of the outer member and the inner member. The reinforcement member comprises: a pair of flat parts spot-welded to a bottom surface part of the channel part; and a W-shaped cross section which projects toward one in the thickness direction between the pair of first flat parts and includes the flat parts spot-welded to the inner member.SELECTED DRAWING: Figure 2
【課題】車体のピラー構造の塑性変形に対する強度を向上させる。【解決手段】本発明の車体のピラー構造は、断面がチャンネル部を有するハット形状のアウター部材、アウター部材の一対のフランジ部間に架設されるインナー部材、および前記アウター部材と前記インナー部材の双方のフランジ部の間に介在する補強部材を備え、前記補強部材は、チャンネル部の底面部にスポット溶接される一対の平坦部と、前記一対の第平坦部の間において、厚さ方向の前記一方に向かって突出し前記インナー部材にスポット溶接される平坦部を含むW字形状の断面を有する。【選択図】図2
