An outer protrusion that prevents the roller from slipping out radially outward is formed on the thin wall portion of the partition portion that partitions adjacent pockets, and an outer protrusion prevents the roller from slipping out radially inward on the inner diameter side of the thick wall portion on both sides of the thin wall portion. In the roller bearing retainer in which inner protrusions are formed, the radial thickness of the thin wall portion of the partition portion is set to be as thick as possible, and the outer protrusion provided on the thin wall portion has a thickness on the protruding side. A cage for a roller bearing, characterized in that a chamfered portion is formed on the inner diameter edge.
