Abstract
In order to decrease gas leakage and in order to restrict the friction between the brush and the rotating shaft, a seal structure for a rotating shaft comprises a stator section, a rotating shaft, a groove, a brush, a spring member, and a connecting hole induces fluid pressure which presses the ring in a direction in which the ring approaches to the rotating shaft so as to be against the spring force of the spring member and make the brush contact the inner surface of the stator, the sealing structure prevents the fluid from flowing between the rotating shaft and the stator having a clearance from the surface of the rotating shaft and flowing in an axial direction of the rotating shaft.
