    摘要： A method for manufacturing a rolling bearing unit is provided to periodically reciprocate a stage (38) in a vertical direction by rotating and driving a servo motor (44) while rotating a roll about a central axis of a hub main body using a roll driving motor (43) in a state in which a processing surface of the roll is pressed against other end surface of a caulking section in an axial direction. A period of the reciprocation is restricted by a relation between a rotation position of the roll about the central axis of the hub main body and an engaged state between concave sections, which are sections between a plurality of processed teeth formed in the processing surface of the roll, and a face spline tooth formed by the concave section.

    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 D h , the number of teeth of the hub-side face splines 21 is taken to be N h , and the number of teeth of a processing surface 31 of the roll 30 is taken to be N r , 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 D h is regulated so that the relationship Nh/Nr = cosθ + (2L/D h ) ● sinθ is satisfied.
