Abstract:
1. A formed part for a vehicle body structural member comprising: a first wall portion extending in a longitudinal direction and in a width direction orthogonal to the longitudinal direction and having two edge portions on opposite sides of the first wall portion in the width direction, at least one of the edge portions is curved such that a center of curvature of the edge portion is positioned on a first side in the width direction; a second wall portion formed so as to i) extend from the at least one edge portion of the first wall portion toward one side in a direction of thickness of the first wall portion, and ii) curve along with the edge portion in the width direction of the first wall portion; a third wall portion which extends from an edge portion of the second wall portion that is opposite the edge portion of the second wall portion which is continuous with the first wall portion, toward an outside in the width direction of the first wall portion; and a linear length difference absorbing portion which is formed on the second wall portion by bending or curving a portion of the second wall portion in a direction of thickness of the second wall portion; wherein the linear length difference absorbing portion includes at least one edge position of the second wall portion in the width direction, and, a height of the linear length difference absorbing portion is zero at the third wall portion or the first wall portion, and the height increases as the linear length difference absorbing portion extends away from the third wall portion or the first wall portion.
