Abstract

A stator vane body which is disposed in a flow path through which a working fluid flows and by which a clearance is formed between the stator vane body and an inner casing; a rotary shaft which is configured to rotate such that an angle of the stator vane body with respect to a flow direction of a main flow of the working fluid is varied; and a connection part which is configured to connect the stator vane body to the rotary shaft are provided. The connection part includes a first guide surface which is configured to guide the working fluid in a direction in which a flow direction of a leakage flow of the working fluid in the clearance which has flowed into toward a leading edge side of the stator vane body is directed in a flow direction of the main flow.
