Abstract: A rolling bearing includes: an inner ring; an outer ring; a plurality of rolling elements; a retainer; and a sealing member. First to third lubricant reservoir portions that store the lubricant are respectively formed on the radially inner side of the retainer, on the inner side of the sealing member, and in an inner peripheral surface of the outer ring at a position near a raceway. An inclined first guide surface that guides the lubricant from the second lubricant reservoir portion toward the raceway is formed in an inner surface of the sealing member. An inclined second guide surface contiguous with the first guide surface and guiding the lubricant toward the raceway is formed in the inner peripheral surface of the outer ring. The first lubricant reservoir portion of the retainer is in communication with pockets of the retainer, which accommodate the rolling elements.

Abstract: In a cage, parallel portions are formed that face a raceway surface of a inner ring in a radial direction and that extend in an axial direction from a small diameter side of a tapered raceway surface toward a side of a large flange part. Grooves extending in the axial direction are formed on inner surfaces of the parallel portions. Between the tapered raceway surface of the inner ring and the inner surfaces of the parallel portions, gaps are formed that allow gear oil to be retained in the grooves through agency of surface tension of the gear oil when the cage is stationary relative to the inner ring.
