PROBLEM TO BE SOLVED: To provide a rolling bearing suppressing heat generation by suppressing stirring resistance accompanying the movement of grease as compared with prior art and enhancing reliability of lubrication. SOLUTION: In the rolling bearing, a ball 13 retained in a retainer 15 is interposed between an inner ring 11 and an outer ring 12, and a bearing space is sealed by a seal 14. The retainer 15 is guided by an inner peripheral surface of the outer ring 12, and a notch SL for feeding a grease Gr to an inner peripheral surface is provided over an end surface of the retainer from an outer diameter surface of the retainer guided by the inner peripheral surface.
