This invention pertains to a filter-attached seal ring provided to a rolling bearing, and is configured to prevent the filter from readily detaching from the seal ring and the sealing performance from decreasing. A rolling bearing in which: a rolling element (13) is included between an outer bearing ring (11) and an inner bearing ring (12); the opening on least one end of a bearing space formed between the outer bearing ring (11) and the inner bearing ring (12) is covered by a seal ring (20) made from a resin or a metal; a filter (23) is detachably provided to an oil through-hole (22) formed in the seal ring (20), the filter (23) being configured to capture foreign material contained in the lubrication oil; the seal ring (20) is engaged with one of the outer bearing ring (11) or the inner bearing ring (12); an annular member (40) composed of a material that is softer than the seal ring (20) is fixed to the seal ring (20); and a lip section (41) that faces, or is in contact with, the other of the outer bearing ring (11) or the inner bearing ring (12) so that a gap is present therebetween is configured by the annular member (40). |
