Both large-diameter side and small-diameter side retainers 3a, 4a are formed to prevent balls 5, 5 from slipping out to the inner diameter side from the inside of respective pockets 10a, 11a. An outer ring 1a, both the large-diameter side and small-diameter side retainers 3a, 4a and the respective balls 5, 5 in the mutually assembled state can thereby be integrally handled as an outer ring side assembly 18. The problem is solved by adopting such a configuration.;COPYRIGHT: (C)2011,JPO&INPIT
