Abstract
An outer retainer includes a pair of annular portions facing each other in an axial direction and a plurality of column members connecting the annular portions. A plurality of window portions is formed by the annular portions and the column members, and an outward flange is provided at one side end thereof. The column member between window portions in predetermined positions is cut and the cut portion on the outward flange side is bent radially outward to be an elastic member. Paired cut-away portions are formed in predetermined portions of the outward flange with the elastic member disposed between the paired cut-away portions. In the thus-configured outer retainer, at least three window portions are disposed between the elastic member and the cut-away portion adjacent to the elastic member in the peripheral direction. Column members between paired cut-away portions are bent outward in the radial direction to be enlarged in diameter.
