Abstract

A rolling bearing is provided with: an inner ring (12) and an outer ring (14) which rotate relative to each other; rolling bodies (15) disposed between the inner ring (12) and the outer ring (14); and a retainer (16) provided between the inner ring (12) and the outer ring (14) and retaining the rolling bodies (15) at equal intervals in the circumferential direction. Flanges (20, 21) extending in the radial direction are provided on the inner diameter side and outer diameter side of the axial ends of the retainer (16). Grooves (30, 31) which form labyrinths (24, 25) together with the flanges (20, 21) are provided at portions of both the inner ring (12) and the outer ring (14) the portions corresponding to the flanges (20,21). The inner surfaces (34, 35) of the flanges (20 21) and the axial end surfaces (38, 39) of the grooves (30, 31) the axial end surfaces (38, 39) facing the inner surfaces (34, 35) of the flanges are tilted relative to the radial direction so as to generate the flow of a lubricating agent.
