Abstract:
A cage 14 comprises: a first wall facing a first end surface 26 of a roller 13 of a rolling bearing 10; a second wall facing a second end surface 27 of the roller 13; and a plurality of bars connecting the first wall to the second wall.

The bars have, on at least one of a first side and a second side in a radial direction, a fall-off prevention portion for preventing the roller 13 accommodated in the pocket 29 from falling off. A connecting portion between the first wall and each of the bars has a first recessed surface 44 located on the first side in the radial direction, and a second recessed surface 43 located on the second side in the radial direction, the first recessed surface 44 being recessed more than the second recessed surface 43.
