PROBLEM TO BE SOLVED: To provide a both-end supporting structure stably supporting a turbine nozzle with a sufficient retention force by a small spring body which can be stored in a narrow space. SOLUTION: When a ceramic turbine nozzle 7 arranged in an inlet side of a turbine 4 of a gas turbine 1 is supported in a nozzle support 27, an outside flange 20 formed on the turbine nozzle 7 and projecting radially outward, an inside flange 19 formed on the turbine nozzle 7 and projecting radially inward, and a pressing mechanism 30 pressing the outside flange 20 against an outside support part 40 of the nozzle support 27 and pressing the inside flange 19 against an inside support part 47a of an inner housing 50 by spring force are provided to support the turbine nozzle 7 in a both-end supporting type.
