Abstract
There is provided a rolling bearing including an inner ring having an inner ring raceway surface, an outer ring having an outer ring raceway surface and a shoulder portion formed on one axial side of the outer ring raceway surface, a plurality of rolling elements which roll between the inner ring raceway surface and the outer ring raceway surface, and a cage adapted to hold the plurality of rolling elements at predetermined intervals in a circumferential direction and having a guided surface which confronts the shoulder portion of the outer ring in such a manner as to be brought into sliding contact therewith. The rotation of the cage is guided through sliding contact of the guided surface of the cage with a guiding surface of the shoulder portion of the outer ring. A guiding space which is a radial space between the guiding surface of the shoulder portion of the outer ring and the guided surface of the cage is made to increase as approaching the rolling elements.
