Zusammenfassung:	A rolling bearing includes an inner ring, an outer ring, a plurality of rolling elements, and a cage. The cage includes an annular body, a plurality of cage prongs, and guide portions placed inward of the cage prongs in the radial direction of the cage such that the guide portions extend from a radially inner part of the annular body toward a second side in the axial direction of the cage, the guide portions being configured to position the cage by making contact with an inner ring raceway. The cage has a groove so as to connect pockets adjacent to each other in the circumferential direction, the groove being configured such that lubricant is present in the groove and a groove width of the groove is increased in the radial direction in the center of the groove in the circumferential direction.
