Abstract
A compressor includes a thrust force adjusting part which is configured to adjusts a thrust force between a back surface of a disc part in an impeller and a casing. The thrust force adjusting part includes an outer sealing part which seals a gap between the back surface and the casing, an inner sealing part which seals the gap at a position away inward in a radial direction, and a throttle formation part which has a throttle part in which the gap in an axial direction is formed to be narrowed inward in the radial direction. An outer space sandwiched by the outer sealing part and the inner sealing part and an inner space sandwiched by the inner sealing part and the throttle part are formed the gap. The width of the throttle part is narrower than the width of the inner space.
