A sealing device having a stationary-side installation ring (11) tightly fitted into and fixed to an outer peripheral stationary-side member (201), a rotation-side installation ring (12) tightly fitted into and fixed to an inner peripheral rotation-side member (202), a stationary-side lip (13) provided on the stationary-side installation ring (11) and whose forward end is made to be slidably in intimate contact with the rotation-side installation ring (12), rotation-side lips (14, 15) formed integrally with the rotation-side installation ring (12) and slidably in intimate contact with the stationary-side installation ring (11), and a pulsar ring (17) formed of a synthetic resin or rubber-like elastic material mixed with magnetic powder, formed integrally with the rotation-side installation ring (12), and magnetized in multiple poles. On the outer periphery of the pulsar ring (17) is extended a flange (17a) positioned on the outer side of the rotation-side lips (14, 15) and closely facing the stationary-side member (201) or the stationary-side installation ring (11). The sealing device with the pulsar ring (17) has excellent sealing ability. |
