PROBLEM TO BE SOLVED: To provide a rolling bearing efficiently lubricating rolling elements, inner and outer ring raceway faces and a cage for a long time by successively supplying the packed grease to the inside of a bearing such as the rolling elements, the inner and outer ring raceway faces and the like, and to remarkably improve the abrasion resistance and high-speed performance. SOLUTION: This rolling bearing 10 has an inner ring 11 having the inner ring raceway face 13, an outer ring 12 having the outer ring raceway face 14, a plurality of rolling elements 16 arranged between the inner and outer ring raceway faces 13, 14, and the cage 17 for rotatably holding the rolling elements 16, and is lubricated by the grease. A grease reservoir groove 15 is formed on a shoulder part of the outer ring 12 continuously from the outer ring raceway face 14 to reserve the grease. COPYRIGHT: (C)2004,JPO
