A seal device has a magnetic force generator for generating a magnetic force in a vicinity of a shaft. A first magnetism transmission member for transmitting the magnetic force generator is disposed adjacent to one side of the magnetic force generator. A second magnetism transmission member for transmitting the magnetic force generated by the magnetic force generator is disposed adjacent to another side of the magnetic force generator. A slide bush is disposed and secured between an inner flange of the second magnetism transmission member and the shaft. A seal member for sliding relative to an outer peripheral surface of the shaft, is accommodated in a sealing. And, a magnetic fluid is held between the shaft and the magnetism transmission member by the magnetic force generated by the magnetic force generator. |
