Abstract

Provided are: an environment-friendly synthetic resin cage that uses a 100% biomass raw material and therefore aims for carbon neutrality while having performance as a bearing in a conventional process; and a rolling bearing incorporating said cage. A crown-type cage for holding a plurality of rolling elements incorporated between an inner ring and an outer ring is produced with a polyamide resin composition containing a 100% biomass-derived raw material with a reinforcing material contained therein, wherein the raw material is polyamide 410 and 10-40 wt % of the reinforcing material is contained therein.
