METHOD OF MANUFACTURING SOCKET OF JOINT DEVICE

摘要

A method of manufacturing a socket (11) of a joint device (10) capable of easily increasing a productivity, comprising the steps of a forging step for forming an intermediate formed body (51) having a tubular base part (53), a first step part (55), and a second step part (56) by forging a material and a press step for forming a cover installation part (31) between a flange part (58) and a base part (53) by press-forming the intermediate formed body (51) to deform the second step part (56) so as to form the flange part (58).
