摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a dead-end cylindrical member by which in ironing of the cylindrical part of the dead-end cylindrical member, the flow of a material to the side of an opening part of the cylindrical part is prevented, consequently undercut parts which are formed on the inner periphery of the cylindrical part are accurately formed.SOLUTION: The method of manufacturing the dead-end cylindrical member having an opening part at one end and having the undercut parts in the inner peripheral surface in a view from the side of the opening part, includes a preparatory step S1, a punch setting step S2, an ironing step S3 and a formed article taking-out step S4 which are performed in order. In the punch setting step S2, an ironing punch which has projecting parts for forming the undercut parts in the inner peripheral surface of a base material to be formed and is expandable and shrinkable in the radial direction is set by making the ironing punch fit to the inner periphery of the base material to be formed. In the ironing step 3, ironing is performed by press-fitting the base material to be formed into the ironing hole of the die in the axial direction in a state in which the outside surface of the bottom and the end face of the opening part of the base material to be formed are restrained from both axial-direction sides of the cylindrical shape, thereby the undercut parts are formed.
