PROBLEM TO BE SOLVED: To provide a resin cage for a rolling bearing which can be used continuously under the circumstance of the high temperature more than 150 deg., and generates no damage in the form removing time and the snap fit time of a rolling element by having a high tenacity. SOLUTION: By using a polymer alloy having a polyphenylene sulfide resin and a polyamide resin as the main component as a resin component, a resin cage for rolling bearing in which claw parts 12a and 12b or the like are not broken in a from removing time, by providing an undercut part by making a pocket 11 in a spherical surface, and has a tenacity not to break the claw parts 12a and 12b or the like, in the assembling time to the pocket 11 by the snap fit of a rolling element, and a heat-resisting property to bear to the using at the temperature more than 150 deg., concurrently, is obtained.
