Abstract

A rolling bearing is provided wherein one open end of a bearing space formed between an outer race and an inner race is covered with a sealing ring provided with oil flow holes provided with filters. The sealing ring includes engaging portions provided on the sealing ring in a protruding manner along a circumferential direction thereof, and engaged in recesses provided on the inner race. An annular member made of a material softer than that of the sealing ring is fixed to the sealing ring. The annular member includes a lip portion facing the outer race with a gap or kept in contact with the outer race. The sealing ring is formed by injection molding a resin, and weld lines generated during the injection molding are formed in portions of the sealing ring corresponding to radial directions along which the oil flow holes are not disposed.
