Claim:
A sealing device with tone wheel comprising a slinger fixedly fitted onto a rotary member, a core member fixedly fitted into a stationary member, and an elastic seal member attached to the core member, the elastic seal member having a plurality of seal lip portions elastically and slidably contacting with the slinger, thereby sealing a space to be sealed between the stationary member and the rotary member, in which said slinger has a first fitting cylindrical portion to be fitted onto said rotary member and a flange like portion disposed opposite to said space having an outer surface opposite to said space and extending in its radial direction from an outer edge of said first fitting cylindrical portion, comprises; an attachment surface to which said tone wheel is attached, and an extended surface to which said tone wheel is not attached, extending in the direction of said stationary member, wherein, said core member has at least a second fitting cylindrical portion to be fitted into said stationary member, whose outer end opposite to said space projects outwardly beyond said outer surface of said first fitting cylindrical portion of said slinger, and one of said plurality of said seal lip portions has an end which contacts elastically and slidably with said extended surface in such manner that the end returns toward said space, whereby said flange like portion is clamped by one of said plurality of seal lip portions outside and inside thereof, and wherein the base portion of said seal lip portion which elastically and slidably contacts with said extended surface has a projected portion which projects axially outside relative to the outer surface of said tone wheel.
