As the size and weight of automobile parts and the reduction in cost have progressed, resin cages have been widely used as cages for rolling bearings. In addition, as the cost of a cage for a rolling bearing for a machine tool spindle has been reduced, a cage made of resin has come to be used. As the resin material, polyamide 66, polyacetal, polybutylene terephthalate, polyimide, phenol resin and the like are used.

The range of the weight% is preferable because when the compounding ratio of the glass fiber is less than 10% by weight, the reinforcing effect by the glass fiber is extremely reduced, and it becomes impossible to obtain the strength required as a cage for a rolling bearing. If the content exceeds 10% by weight, the flexibility inherent in the polyamide resin is impaired, and the snap fit required when the rolling element is incorporated is extremely reduced.

（攻撃性）が小さくなることによる。In the cage for a rolling bearing according to the present invention, the glass fibers have an average fiber length of 200 to 60.
Although it is desirable to use a thing of 0 μm, this is because if the average fiber length is less than 200 μm, the reinforcing effect by the glass fiber is not sufficiently exerted, and even if the average fiber length is long, This is because the glass fiber is broken at the time of compounding or injection molding, and it is difficult to leave a glass fiber exceeding 600 μm in a molded product. Further, as the glass fibers, those having an average diameter of 6 to 13 μm are preferably used.
The use of a material having a diameter of less than m causes an increase in cost, while the use of a material having a diameter of more than 13 μm results in a reduction in friction and wear characteristics. In addition, it is preferable to use glass fibers having an average diameter of 6 to 10 μm. This is because the smaller the diameter is, the smaller the effect (aggression) on the sliding partner is.
