PROBLEM TO BE SOLVED: To provide a sealing device decreased in slide resistance and a stick slip and having high reliability. SOLUTION: The sealing part is provided with a central part 2b in the axial direction making close contact with a shift and a taper part 2c inclining in the direction in which a distance with the shaft is increased from the central part 2b toward the high pressure side during action of pressure of an object fluid to be sealed. The taper part 2c forms a slide surface, making close contact with the shaft during action of pressure of the object fluid to be sealed. |
