Abstract:
To provide a sealing device which can suppress mutual magnetic adsorption when laminated in a plurality of pieces, and can reduce an occupied volume.SOLUTION: A sealing device 9 seals an annular space between a fixed-side member 2 and a rotating-side member. A magnetic encoder comprises a support member 11 having an attachment plate part 112 extending to a radial direction, and attached to the rotating-side member, and an annular magnet 12 attached to the attachment plate part. The seal member comprises: a core material 21 having a cylinder part 211 attached to the fixed-side member, and a circular disc plate part 212 which is arranged so as to oppose the attachment plate part from the cylinder part; and an elastic material-made seal body 22 having a seal lip 22a fastened to the core material, and approximating or contacting with the support member. At least the circular disc plate part of the core material is composed of a non-magnetic material, and abuts on the annular magnet in the adjacent sealing device when a plurality of the sealing devices are laminated in an axial direction.SELECTED DRAWING: Figure 2
