| description | A cage (40) includes: an annular body (42) having pocket holes (42a) for receiving balls (30); and a resin portion (44) formed through injection molding of a resin containing a solid lubricant with the body (42) being set as an insert component. The resin portion (44) includes: first parts (44a) formed along inner peripheral surfaces of the pocket holes (42a) of the body (42) to form pocket surfaces (46) to be held in sliding contact respectively with the balls (30); and a second part (44b) formed along an outer peripheral surface (or inner peripheral surface) of the body (42) to form a guide surface (48) to be held in sliding contact with an outer ring (20) (or inner ring (10)). The first parts (44a) and the second part (44b) are formed integrally with each other. Weld lines (W) of the resin portion (44) are formed at positions of avoiding exposure of the weld lines (W) at both end portions of the pocket surfaces (46) in a cage circumferential direction. |
