Abstract
A bearing supporting a rotational shaft of an electric motor includes an outer ring, an inner ring, and an annular retainer disposed between the outer and inner rings for holding a plurality of metal balls so that the balls are rollable. The retainer has a plurality of grease reserve portions formed in its upper end. Each grease reserve portion is enclosed partially by a peripheral wall. The gross amount of grease injected into the bearing is about 10% or less of a volume of an inner space of the bearing defined by the outer and inner rings and upper and lower sealing plates with the retainer and the balls in position.
