Abstract: PROBLEM TO BE SOLVED: To provide a stator assembly having a row of stator vanes repeatedly positionable after replacement, having an allowable level of durability and replaceability. SOLUTION: This stator assembly comprises a plurality of vanes extending into an operating medium gas flow passage through a case extending in circumferential direction. In this case, the stator assembly comprises a surface 76 facing inward on a base part 48, and the inward facing surface 76 is connected, in the state of being installed, to a flat surface 74 corresponding to a non-flow passage surface of a casing at a position of each vane. In one embodiment, these surfaces are on the same plane.

Abstract: PROBLEM TO BE SOLVED: To provide a stator assembly having a row of stator vanes with an allowable level of durability and replaceability. SOLUTION: This stator assembly comprises shrouds. The detail of various coinfigurations limiting the movement of stator vanes 28 into a flow path by the limitation of the shrouds is expanded. For example, a clip member 62 extends throiugh an opening part 64 located at a vane tip part 52 of the stator vane 28, and the clip member 62 is disposed on a non-flow path surface of an inside shround 56 so as to limit the vane tip part 52 of the stator vane 28 for an inward movement.
