摘要：
Construction is achieved that is capable of preventing the formation of radial streaks in the tip-end surfaces of teeth of hub-side face splines 21. When a swing center distance is taken to be L, a swing angle that is the inclination angle of the center axis of a roll 30 with respect to a main hub body 8 is taken to be θ, the pitch diameter of the hub-side face splines 21 is taken to be Dh, the number of teeth of the hub-side face splines 21 is taken to be Nh, and the number of teeth of a processing surface 31 of the roll 30 is taken to be Nr, the position relationship of the main hub body 8 and the roll 30, or in other words, at least one of the swing center distance L, the swing angle θ, and the pitch circle diameter Dh is regulated so that the relationship Nh/Nr=cos θ+(2L/Dh)·sin θ is satisfied.
