造。 A plurality of stator vane segments are formed by making the blade part of the stator vane disposed on the upstream side of the gas turbine and the walls at both ends of the vane part of the gas flow path in which this vane part is disposed, respectively, from ceramic. The vane segments are circumferentially connected to each other to form an annular stator vane assembly in the housing, and a ceramic ring-shaped support member is interposed between the housing and the stator vane segments, and this support member is attached to the housing side. A stator blade structure for a gas turbine, which is characterized in that it comes into elastic contact with the stator blade and engages with a groove provided on the stator blade side with a predetermined gap.
