Abstract
A rotary machine is provided with: a flange section protruding in the radial direction of a rotating shaft which rotates about an axis and rotating together with the rotating shaft; a stationary bush disposed at a distance in the direction of the axis from the flange section, surrounding the outer peripheral surface of the rotating shaft, and provided in a housing supporting the rotating shaft so as to be immovable in the direction of the axis relative to the rotating shaft; and a rotation bush which is disposed between the flange section and the stationary bush so as to be sandwiched there between in the direction of the axis, covers the outer peripheral surface of the rotating shaft, and is rotatable relative to the rotating shaft and the housing while floating in fluid. The rotation bush has, on the surface thereof which faces the direction of the axis, a land surface and a tapered surface which is continuous with the land surface.
