<P>PROBLEM TO BE SOLVED: To provide a plastic cage withstanding use at high temperature without deformation while being inexpensive and especially withstanding use for a long period under high temperature, high speed rotation, and high humidity conditions, and to provide a rolling bearing including the plastic cage and suitable for use under the high temperature, high speed rotation, and high humidity conditions. <P>SOLUTION: The plastic cage for the rolling bearing is formed by heating and crosslinking a molded body of polyamide resin composition containing polyfunctional monomer having at least two or more carbon-to-carbon double bonds and is increased in strength without adding fibrous material. The rolling bearing includes the plastic cage. <P>COPYRIGHT: (C)2011,JPO&INPIT |
