Abstract
A sealing device includes a floating ring in a space between the outer circumference of a rotating shaft and the inner circumference of a housing, and a multi-layered cylindrical body including a plurality of elastically deformable cylindrical thin plates layered on top of each other provided between an outer peripheral surface of the floating ring and an inner peripheral surface of the housing, so as to impart a radial restoring force against the eccentricity of the rotating shaft to restore it to its center position, and a tangential damping force to reduce the whirling of the rotating shaft.
