A method of manufacturing a constituent member of a constant-velocity joint includes: performing plastic working; and performing hardening of a material. The plastic working is performed with a material of the constituent member heated to a predetermined working temperature range. The hardening of the material is performed by utilizing heat applied for heating to the working temperature range in performing the plastic working as heat for the hardening of the material and cooling the material after performing the plastic working.

Method of manufacturing constituent member of constant-velocity joint

A constant velocity joint comprises an outer race, inner race and torque transmitting elements. The outer race has a cylindrical hollow part with an opening at one end and plural walls on an inner surface of the cylindrical hollow part. At the opening of the cylindrical hollow part, the walls have projections formed by a pin-drive. The inner race is assembled with the torque transmitting elements and press-fitted into the cylindrical hollow part of the outer race.
