摘要： Hydroforming into a hollow structural component by pressing a joined plate member outwardly. A largest width is set to an area of a blank portion of the joined plate member extending to between outer peripheral portions of the recessed spaces from a longest constant portion of an internal space formed by the recessed spaces, the longest constant portion being constant in its inner circumferential length and extending the longest in the internal space. A width of an area of the blank portion extending to between the outer peripheral portions from a portion shorter than the longest constant portion is set such that the smaller the length of the portion which is shorter than the longest constant portion is compared to the longest constant portion. The smaller the width of the area extending from the shorter portion is compared to the width of the area extending from the longest constant portion.
