1. A piston rod manufacturing method of manufacturing a piston rod by joining a solid rod main body and a rod head having an annular clevis connected to a load and a solid body portion, comprising:
a first step of joining an end surface of the rod main body and an end surface of the body portion of 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 from the clevis to the body portion; wherein the second step is performed after the first step. |
