Abstract
Grooves as ball rolling grooves are formed in a side peripheral wall of a preparatory formed body that is to be an inner member. A recess opened so as to be continuous to curved bottom sections of the grooves, which face a through-hole, is formed in one end surface of the preparatory formed body. In carburizing, carburizing gas entering into space between the through-hole and a support shaft member flows through the recess after coming into contact with inner teeth, and is then discharged to the outside of the preparatory formed body via the curved bottom sections of the grooves. On the contrary, the carburizing gas having been in contact with the curved bottom sections of the grooves flows through the recess to come to be in contact with the inner teeth and is then discharged through the space.
