Abstract
A rolling bearing includes an outer ring, an inner ring, a plurality of balls disposed between the outer ring and the inner ring and allowed to roll, and a snap cage that is made of resin and holds the balls. The snap cage includes an annular main portion and a plurality of cage bars. The cage bars each protrude from a right side surface of the main portion. Pockets are formed between the cage bars to house the respective balls. An inner circumferential surface and an outer circumferential surface of each of the cage bars in a radial direction have respective tilted surfaces that form a tapered shape in an axial direction. This allows lubricant oil to flow well in the rolling bearing in both directions.
