PROBLEM TO BE SOLVED: To reduce the noise during the operation and the amount of the air to be supplied in a rolling bearing applying the air oil lubrication. SOLUTION: A slant face part 2b is mounted on an outside cylindrical surface of an inner ring 2 of a rolling bearing 1, and a nozzle member 6 is mounted along the slant face part 2b at an interval. An air oil discharging groove 7 is circumferentially formed on the nozzle member 6, and an air oil discharging hole 8 is opened in the discharging groove 7. The discharging hole 8 is directed to the slant face part 2b to allow the discharged air oil to be directly sprayed onto the inner ring slant face part 2b, and inclined to the slant face part 2b.
