To sufficiently suppress deterioration of roundness of a peripheral surface of an outer ring and the track of the outer ring regardless of fitting of a peripheral edge part of a sealing plate 1a and an inside surface at one end of the outer ring when the sealing plate 1a is attached to the one end of the outer ring with radial thickness reduced.
Recessed parts 6, 6 recessed to the inner diameter side are respectively formed at a plurality of parts at equal intervals in the circumferential direction in a peripheral edge part of an elastic material 3a constituting the sealing plate 1a. The peripheral edge part of the elastic material is fitted to a lock groove formed on the inside surface at the one end of the outer ring with interferences in relation to the circumferential direction with the sealing plate 1a attached to the outer ring.
