Abstract
A rolling bearing includes an inner ring, an outer ring, a plurality of balls, and a cage that holds the balls. The inner ring is a rotating ring, and the outer ring is a fixed ring. An annular groove for creep suppression is formed in a fitting surface of the rolling bearing that is fitted on a mating member to which the outer ring is attached. The annular groove has a groove main body portion and inclined groove portions located on opposite sides of the groove main body portion in an axial direction and formed to be shallower than the groove main body portion such that the depth of each of the inclined groove portions increases toward the groove main body portion. The inclined groove portions come into contact with the mating member when the outer ring is elastically deformed by a radial load received from the balls.
