Structural member and method for producing the same

A method for producing a structural member, comprising:

• a preparing step of preparing a starting material made of a metal sheet;
• and
• a forming step of performing forming by subjecting the starting material to cold press working by using a press tooling that includes a pad, an upper die, and a lower die,
• wherein the lower die includes:
• a first lower die including a first crest that intersects a pressing direction, a first shoulder portion extending along an end edge of the first crest, and a first side surface connected to the first crest via the first shoulder portion;
• a second lower die including a second crest that intersects the pressing direction, a second shoulder portion extending along an end edge of the second crest, and a second side surface connected to the second crest via the second shoulder portion, the second lower die being a separate body from the first lower die;
• and
• a corner portion provided between the first shoulder portion and the first side surface, and the second shoulder portion and the second side surface, the corner portion having a shape recessed inwardly of the lower die as viewed from the pressing direction, and
• the forming step includes:
• a first step in which, in a state where the first lower die and the second lower die are arranged so that the second side surface is at a position retreated with respect to the first side surface as viewed from the pressing direction, the pad and the upper die are relatively brought closer to the lower die in the pressing direction, and the starting material is sandwiched between the pad and the first lower die to be held;
• and
• a second step in which, in a state where the starting material is held by the pad and the first lower die, the upper die is further relatively brought closer to the lower die in the pressing direction to sandwich the starting material between the upper die and the first lower die, and the second lower die is moved so that the second side surface is aligned with the first side surface as viewed from the pressing direction, so as to sandwich the starting material between the upper die and the second lower die.
