PROBLEM TO BE SOLVED: To provide a molded article for a vehicle body structural material, eliminating or reducing unnecessary deformation occurring due to stress caused by a difference in line length before and after molding. SOLUTION: Bent parts 34, 36 are formed at the first vertical wall part 22 continuing from a head wall part 12, and bent parts 44, 46 are formed at the second vertical wall part 26 continuing from the head wall part 12. Gap of the line length caused before and after molding on the first vertical wall part 22 side is compensated (absorbed) by total sum of projection dimension of the bent parts 34, 36, and the gap of the line length caused before and after molding on the second vertical wall part 26 side is compensated (absorbed) by total sum of projection dimension of the bent parts 44, 46. Generations of tensile stress on the first vertical wall part 22 side and compression stress on the second vertical wall part 26, are thereby prevented or restrained. COPYRIGHT: (C)2009,JPO&INPIT
