A wheel bearing includes a sealing device
positioned between inner and outer members
. This sealing device
includes an elastic member
, which eventually forms an encoder grid and is provided on a first annular sealing plate
. A second annular sealing plate
is provided with sealing lips
. An engagement
between a cylindrical wall
of the first annular sealing plate
and the inner member
is provided with an elastic member
made of a material dissimilar to that for the elastic material
. This elastic member
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.
