PROBLEM TO BE SOLVED: To provide a ball retainer reduced in rattling when fixed to a bearing while being enabled in molding by pressing work. SOLUTION: On both side faces of the ball retainer 14, bent portions 14a are formed by bending a thin-plate stainless spring steel inward. At the longitudinal end of the ball retainer 14, a lock portion 14b is formed by inclining the thin-plate stainless spring steel. On the back face side of the ball retainer 14, a protruded portion 14c is formed by pressing work. COPYRIGHT: (C)2008,JPO&INPIT
