PROBLEM TO BE SOLVED: To provide a support structure stably supporting a turbine nozzle made of ceramic by strongly pressing it against a nozzle support with large pressing force generated in a small space. SOLUTION: The ceramic turbine nozzle 7 is disposed on an inlet side of a turbine 4 in a gas turbine 1. A flange 20 is formed on the turbine nozzle and protrudes in a radial direction and the flange 20 is pressed and supported against the nozzle support 27 by a booster mechanism 30. The booster mechanism 30 is constructed of a press member 31, which has a spring receiving portion 31a, a fulcrum portion 31b and a pressing portion 31c, a spring body 32 applying spring force to the spring receiving portion 31a and a fulcrum member 33 supporting the fulcrum portion 31b.
