転軸の密封装置。[Claims for Utility Model Registration] A fluid is sealed between a rotating disk that is integrally and concentrically protruding from the rotating shaft in the radial direction, and a fixed member that is positioned around the rotating disk with a gap therebetween, In the device for sealing the rotating shaft by using the centrifugal force of the fluid when the rotating shaft rotates, a first ring-shaped protrusion is provided concentrically on both sides of the rotating disk, and the fixing member includes: Said first
A ring-shaped second protrusion is provided which faces the protrusion on the inner side in the radial direction, and between the first and second protrusion, when the rotating shaft is stopped, the first and second protrusion When the rotating shaft rotates, it is elastically deformed by centrifugal force and
A sealing device for a rotating shaft, comprising: an elastic seal spaced apart from a protruding portion of the rotary shaft, wherein the fluid is sealed radially outward from the seal portion formed by the elastic seal.
