Abstract: A steel base material 11 is subjected to a quenching step, a machining step, a plating step, and a tempering step to form a rod 4. In the quenching step, two axially spaced portions of the steel base material 11 are quenched to form quenched portions 12 and 13. In the machining step, plastic working or cutting is performed on a portion of the steel base material 11 between the two quenched portions 12 and 13 to form a full-circumferential groove 4C1 in a machined portion 4C. In the plating step, the quenched portion 12 is not plated, but a region of the steel base material 11 including the quenched portion 13 is plated to form a coating layer 16. In the tempering step, the quenched portions 12 and 13 are tempered.
