PURPOSE: To prevent a seal tip from being damaged by preventing foreign matter from entering a housing, and to improve the sealability by preventing other seal parts to be fitted to the annular clearance between the housing and a shaft from being damaged. CONSTITUTION: A sealing device is fitted to the annular clearance 30 between a housing 2 to be assembled in a concentrical and relatively movable manner to each other and a shaft 3, and seals the sealed fluid from a flow passage 21 to be open to the annular clearance 30 having the housing. In the sealing device having a seal body 4 provided with a fitting part 7 to be fitted to the housing 2 and a seal lip 8 which is brought into sealable contact with the shaft 3, a filter means 20 to cover the opening part of the flow passage 21 to be open to the annular opening 30 is integrated with the fitting part 7. |
