[SUBJECT] The present invention provides a sealing device capable of preventing the leakage of a sealed fluid over a wider range of from a lower speed to a higher speed without narrowing of a seal gap. [MEANS FOR SOLVING THE SUBJECT] A seal gap 25 is provided between a rotor 3 and a stator 5, and a movable floating ring 6 is disposed in the seal gap 25. The floating ring 6 is formed so that if its thickness T is defined as 1, its length in a widthwise direction perpendicular to a thickness-wise direction is defined as equal to or larger than 3. |
