PROBLEM TO BE SOLVED: To provide a pillar constituting member for a vehicle capable of improving collision safety performance while taking into consideration weight reduction.SOLUTION: A pillar constituting member 12 for a vehicle is constituted by welding a plurality of steel plates 120A-E by at least one joining lines 110a-d being a longitudinal shape and crossing the longitudinal direction, and strength of its upper-lower both-side steel plates is different in respective these joining lines. The first joining lines 110a and 110c inclined to the orthogonal direction to the longitudinal direction of the pillar constituting member 12 for the vehicle are included by at least one piece or more in at least one joining line.SELECTED DRAWING: Figure 1
【課題】軽量化を考慮しつつ衝突安全性能を向上させることができるような車両用ピラー構成部材を得る。【解決手段】車両用ピラー構成部材12であって、長手形状であり、長手方向を横切る少なくとも1本の接合線110a〜dで複数の鋼板120A〜Eが溶接されて構成されており、この接合線それぞれについてその上下両側の鋼板の強度が異なっている。また、少なくとも1本の接合線のうちには車両用ピラー構成部材12の長手方向の直交方向に対して傾斜した第一接合線110a、110cが1本以上含まれている。【選択図】図1
