Rolling bearing

A rolling bearing includes an inner ring, an outer ring, a plurality of balls, and a cage in which a plurality of pockets that accommodate the balls are formed along the circumferential direction. The cage is a snap cage that has an annular body provided on one side in an axial direction, and a plurality of prongs provided so as to extend from the annular body toward the other side in the axial direction. Spaces on the other side of the annular body in the axial direction and between the prongs which are adjacent to each other in the circumferential direction serve as the pockets. A pocket surface of the pocket that faces the ball is a part of a spherical surface. The cage can contact the inner peripheral side of the outer ring for positioning in the radial direction.
