Abstract

See full text

An axial-flow fluid machine provided with: a retainer ring holding a stationary blade train; a casing supporting the retainer ring; and an eccentric pin. An engagement part of the casing has a protruding section protruding to the retainer ring side. An engagement part of the retainer ring has a pair of wall plate sections forming a groove into which the protruding section is put. In the casing, a penetration hole is formed extending in a radial direction so as to be centered about a penetration center position that is biased to an axial upstream side in a region of the casing where the engagement part is formed. In the engagement part of the casing, a portion on an axial downstream side relative to the penetration hole exists in the entire circumferential area. The eccentric pin is inserted into the penetration hole.
