Abstract
A bearing includes an inner ring, an outer ring, and a plurality of rolling elements. In the bearing, each of an inner ring raceway surface and an outer ring raceway surface has a contact area that comes into contact with the rolling elements, and a non-contact area that is formed adjacent to an outer side of an end portion of the contact area and does not come into contact with the rolling elements. A lubricant retaining portion having a recessed portion and a large number of non-uniform projections and depressions is formed at the non-contact area of at least one of the inner ring raceway surface and the outer ring raceway surface.
