1. A rolling bearing comprising: an inner ring including an inner ring raceway surface on an outer circumference; an outer ring including an outer ring raceway surface on an inner circumference and a shoulder portion formed on one axial side of the outer ring raceway surface in such a manner as to project radially inwards from the other 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 whose rotation is guided through sliding contact of part of an outer circumference thereof with the shoulder portion of the outer ring, wherein the outer circumferential surface of the cage comprises a tapered surface in which the outer circumferential surface is formed in such a manner as to decrease in diameter as extending from the one axial end portion to the other axial end portion or a curved surface in which a section including an axis thereof forms a curve which can be differentiated.
