<p><P>PROBLEM TO BE SOLVED: To provide a retainer capable of ensuring rigidity and strength required in high speed rotation without reducing the number of accommodation of rolling bodies and without making the retainer heavy in weight. <P>SOLUTION: In the retainer 10 for the bearing made of resin, a plurality of pocket parts 6 for retaining the rolling body 5 are formed in a circumferential direction by a plurality of pillar parts 12. Two division bodies 20, 30 divided at an axially intermediate position are assembled to form the retainer. Engagement parts 40, 50 for connecting both division bodies are provided on distal ends of division pillar parts 22, 32 of both division bodies, and they are formed so as to mutually have guide slide surfaces having a slope so that assembling is facilitated. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
