ABSTRACT:
A push rod is manufactured by projection-welding a bottom surface of an end element to a tapered annular end surface of a pipe. To prevent some inclination from arising between the bottom surface of the end element and the annular end surface of the pipe when they are tightly pressed against each other, the bottom surface is formed integrally with a plurality of rose seats of wedge shape in cross section that extend radially with respect to the axial center of the end element. Projection-welding is performed after the rose seats are brought into confronting contact with the tapered annular end surface of substantially triangular shape in cross section.
