Abstract
An outer peripheral surface of the small-diameter step portion is formed with an engagement groove extending in a circumferential direction. The retainer plate has a plurality of engagement claws protruding radially inward from an inner periphery of the retainer plate defining the fitting hole and configured to be engaged to the engagement groove. In a state that the fitting hole is fitted to the small-diameter step portion, the engagement claws are formed by axially pressing the inner periphery of the retainer plate, including at least thickness reduction parts formed in advance at a peripheral edge between an inner peripheral surface of the fitting hole and a side surface of the retainer plate, and plastically deforming the inner periphery of the retainer plate so as to protrude radially inward, and the engagement claws are engaged to the engagement groove.
