Abstract
A rolling bearing includes rolling elements interposed between rolling surfaces of an inner ring and an outer ring. An oil supply hole for lubricant oil supply is provided in the outer ring so as to communicate between an outer diameter surface of the outer ring and a position, near the rolling surface, in an inner peripheral surface of the outer ring. A circumferential groove is provided on the outer diameter surface of the outer ring so as to communicate with the oil supply hole to introduce, to the oil supply hole, a lubricant oil supplied from a circumferential position outside the bearing that is different from that of the oil supply hole.
