Claim:
A rolling bearing comprising: an outer ring; an inner ring; a plurality of rolling elements rotatably provided between the outer ring and the inner ring; and a cage which holds the plurality of rolling elements with a predetermined interval in a circumferential direction thereof and of which rotation is guided by the outer ring, the inner ring or the rolling elements, wherein the cage comprises a first annular portion which is disposed at an end portion thereof in an axial direction, and a plurality of pillar portions which protrude in the axial direction toward the rolling elements from an inside surface, facing the rolling elements in the axial direction, of the first annular portion and which are arranged in the circumferential direction thereof so as to form pockets defined between the pillar portions and configured to house the rolling elements, respectively, wherein a seal gap configured so as to restrict a flowing of lubricant is formed between the first annular portion and one of or both the outer ring and the inner ring which do not guide the cage, wherein an inclined outside surface is disposed on an opposite side of said first annular portion from said inside surface in an axial direction, said inclined outside surface inclines axially away from the pillar portions as the inclined outside surface extends radially outward opposite from the rolling elements in the axial direction, and wherein the inclined outside surface extends from a radially innermost portion of the cage to a radially outermost portion of the cage.
