摘要:
A piston rod manufacturing method of manufacturing a piston rod by joining a solid rod main body and a solid rod head includes a first step of joining respective end surfaces of the rod main body and the rod head by friction welding; and a second step of performing boring process on an axial center portion from the rod head side so as to penetrate through a joining face between the rod main body and the rod head.
