摘要： PROBLEM TO BE SOLVED: To provide a vane structure of a gas turbine and the gas turbine, capable of reducing rising of temperature in a stator vane, while restraining increase in weight. SOLUTION: A thermal insulation part 30 capable of forming a gas layer by having a plurality of cylindrical body parts 31, is arranged on the shroud inner surface part 26 side of the stator vane 15. Thus, even when combustion gas flows to the shroud inner surface part 26 side of the stator vane 15, heat of the combustion gas can be restrained from being transmitted to the stator vane 15 by the gas layer formed of the thermal insulation part 30. Since the heat of the combustion gas is restrained from being transmitted to the stator vane 15 by gas, the weight increase when restraining the temperature rise in the stator vane 15, becomes only the thermal insulation part 30 being a gas layer forming means, and the weight increase is reduced more than when increasing the thickness of a hub shroud 25. As a result of this, the temperature rise in the stator vane 15 can be reduced while restraining the increase in the weight. COPYRIGHT: (C)2008,JPO&INPIT
