<P>PROBLEM TO BE SOLVED: To provide a cage for a rolling bearing, capable of properly supplying lubricant between a rolling element and a recessed surface part of a pocket by causing the lubricant to efficiently contribute to lubrication while suppressing an increase in manufacturing cost of the cage and suppressing an increase in a rotation torque by suppressing an increase in agitation resistance. <P>SOLUTION: This cage 40 for the rolling bearing includes: pockets 41 rollably holding a plurality of rolling elements and having recessed surface parts 42 where the rolling elements are located; pillar parts 43 formed between the pockets 41; and hollow parts 44 formed in the pillar parts 43. The hollow part 44 is partitioned by a bridge part provided at the pillar part center, and the hollow part 44 is opened at the recessed surface part 42. <P>COPYRIGHT: (C)2013,JPO&INPIT |
