PROBLEM TO BE SOLVED: To provide a turbine nozzle supporting structure which can decrease thermal stress and can restrain the nozzle from being inclined forward so as to prevent a decrease in the nozzle efficiency, and to maintain the sealing performance between the inside and the outside of the nozzle in such a state that the nozzle is exposed to high temperature gas within the nozzle and cooling air outside the nozzle. SOLUTION: The turbine nozzle supporting structure includes the turbine nozzle 10 located between a combustor 2 and a turbine bucket 4 so as to introduce the high temperature gas from the combustor into a turbine on the downstream side, a nozzle support member 14 fixed to the inner side of the turbine nozzle, and a stopper member 16 fixed to the outer side of the turbine nozzle. The turbine nozzle 10 comprises a plurality of circumferentially separated nozzle segments 12. An inner end of each nozzle segment 12 is attached to the nozzle support member by an axial attachment pin 18 in a circumferentially movable manner. An outer end of the nozzle segment 12 is partially fitted in the stopper member in a thermally expandable manner. COPYRIGHT: (C)2004,JPO
