A groove is formed on one end face side of a cage including a plurality of pockets for holding individually rolling elements which extends circumferentially along a full circumference of the cage about a rotational center thereof and has a bottom portion which communicates individually with the plurality of pockets, and a distal end portion of a nozzle of an oil supply unit is inserted into the groove, whereby the generation of disturbance to airflow and negative pressure in the vicinity of an opening of the nozzle is suppressed when a rolling bearing rotates, so that lubricating oil supplied from the nozzle is allowed to reach the rolling elements in an ensured fashion.
