<p>A magnetic encoder-equipped sealing device having, in combination, a slinger and a lip seal, wherein, when multiple of such sealing devices are stacked on each other, their adhesion prevention projections do not fall inward, securing stability of the stacked sealing devices. The magnetic encoder-equipped sealing device has, in combination, the slinger attached to either of two relatively rotating members and the lip seal attached to the other. The slinger has a magnetic encoder at one end face in the axial direction. The lip seal is formed by attaching a seal lip to an attachment ring and is slidably in intimate contact with the slinger.An adhesion prevention projection, formed from a rubber-like elastic body, is provided on the other end face in the axial direction of the attachment ring to prevent mutual adhesion of sealing devices when they are stacked on each other. The adhesion prevention projection (7) has a tapered cross-sectional shape in which an inner peripheral side-face (7a) of the projection (7) tilts relative to a rotation axis (O) at an angle greater than the tilt angle of an outer peripheral side-face (7b).</p> |
