a

of the first annular sealing plate

11

and the inner member

1

is provided with an elastic member

20

made of a material dissimilar to that for the elastic material

14

. This elastic member

20

may be a rubber coated layer, resin paint layer, a thin film of adhesive material or a ring-shaped rubber member. Thereby, any possible ingress of water across an engagement surface of the annular sealing plate is prevented, accompanied by increase of the lifetime of the bearing, with no problem associated with separation and displacement of the annular sealing plates. The magnetic flux density can also be easily secured.
