Abstract
A method and apparatus for manufacturing a press component without generating cracks in a flange on an inner circumferential side of a curved portion includes press working by a free bending method on a blank consisting of an ultra-high tensile strength steel sheet. A press component is manufactured by performing cold press working on a blank of an ultra-high tensile strength steel sheet. By the press working, a material inflow facilitating portion that increases the amount by which a portion of the blank to be formed into an end portion of the press component flows into a portion of the blank to be formed into a flange on an inner circumferential side of the curved portion of the press component is provided in the vicinity of the portion of the blank to be formed into the flange on an inner circumferential side of the curved portion of the press component.
