Rolling bearing
A rolling bearing comprises rollers and a retainer which holds the rollers. On an inner diameter surface of each of annular regions in the retainer, a cutout is formed from an axially outer side end surface of the retainer toward an inner side of the retainer. Each cutout has an outer diametrical position on a more radially outer position than an outer diametrical end of an inner-side projection of the retainer.
