A strut cover for a gas turbine includes: a cylindrical sheet metal member having a hollow portion; and a flare member that is connected to one end of the cylindrical sheet metal member in an axial direction of the cylindrical sheet metal member and includes a curved portion having an outer surface such that a distance from a center axis of the cylindrical sheet metal member to the outer surface increases with increasing a distance from the cylindrical sheet metal member in the axial direction. The flare member has a thickness larger than a minimum thickness of the cylindrical sheet metal member at least in the curved portion.

Strut cover, exhaust casing, and gas turbine

A gas turbine is provided with an exhaust diffuser in which an exhaust flow path for circulating exhaust gas from a turbine is formed, and a cooling device for cooling a structure facing the exhaust flow path in the exhaust diffuser. The cooling device has a guide part in which a guide flow path for circulating a cooling medium is formed and which is configured to guide the cooling medium to the structure, and a switching part able to switch between a first state where a flow rate of the cooling medium flowing through the guide flow path is a first flow rate corresponding to a flow rate during a rated operation and a second state where the flow rate of the cooling medium is a second flow rate higher than the first flow rate.
