PROBLEM TO BE SOLVED: To provide a sealing device for a rotating shaft which the fitment accuracy is maintained at the high speed revolution in the hot environment and the deformation on the sealing surface is prevented while the sealing device is pressed onto the rotating shaft. SOLUTION: The sealing device comprises a cylindrical member represented by a sealing liner 32 having a bellows portion 34 forming deformable portion which a free end is pressed toward radial direction and contact with the outer periphery of the rotating shaft represented by outer shaft 7 or inner shaft 8 and is placed between a floating ring member 31 and the rotating shaft. It is characterized in that the sealing surface does not deform when pressing onto the rotating shaft and the deformable portion of the cylindrical member can be deformed by the centrifugal force and heat expansion while the rotating shaft is turning at high speed with high temperature.
