Abstract
A stator vane is configured to guide a flow of a fluid flowing in an axial direction. The stator vane includes a stator vane body which extends in a radial direction with respect to an axis and includes a radially outer end portion which is supported by a casing and a stator vane inner circumferential surface which is an end surface facing an inside in the radial direction and faces an outer peripheral surface of a rotary shaft via a clearance, and an internal channel which is defined inside the stator vane body and includes a first end which is open on the stator vane inner circumferential surface and a second end which is connected to a pressure source having a pressure different from a pressure around the stator vane body.
