Abstract
Provided is a novel producing method for enabling to easily produce a high-quality joint member by powder metallurgy, where the joint member has a male engaging portion and a female engaging portion arranged coaxially at different positions in the axial direction. A male member (14) having a male engaging portion (10) and a female member (16) having a female engaging portion (12) are formed separately by powder metallurgy, and then, the male member (14) and the female member (16) are combined in a relatively non-rotatable manner.
