Abstract
A rolling bearing includes an inner ring, an outer ring, a plurality of balls, and a cage that holds the balls. An annular groove for creep suppression is formed in a fitting surface that is fitted on a housing to which an outer ring is attached. The annular groove has a groove bottom portion and a pair of tapered surface portions extending from opposite sides of the groove bottom portion in an axial direction and defining a groove width that is larger toward the fitting surface. In a section including a bearing center line, each of the tapered surface portions has a linear sectional shape inclined to the fitting surface.
