| 1. A rolling bearing comprising:
inner and outer members rotatable relative to each other;
a plurality of rolling elements rotatably interposed between said inner and outer members; and
a retainer rotatably holding said rolling elements, wherein said retainer is made of a resin composition having a flexural
modulus of at least 3,500 MPa at 180° C. and a heat-resistant temperature of at least 150° C., wherein said resin composition
is a polyamide 46 containing glass fiber in an amount of from not smaller than 30% by weight to less than 50% by weight, and
wherein a tensile strength drop of the resin composition after 1,000 hours elapsed at the temperature of 150° C. is within
10%., wherein
said resin composition consists essentially of two components.
