PURPOSE:To absorb thermal expansion and shrinkage by fixing the inner peripheral end of a stator blade made of ceramic to an inner side support ring through a heat insulating member which is in surface contact with said end and also fixing the outer peripheral end to the outside support ring through a heat insulating member in surface contact with said end and a plate spring. CONSTITUTION:The inner peripheral end of a turbine stator blade 8 made of ceramic material is fixed to an inner side support ring 22 through a heat insulating member 21 which is in surface contact with said end, while the outer peripheral end of said blade is fixed to an outside support ring 12 through a heat insulating member 35 in surface contact with said end and a plate spring 36. Since the stator blade 8 is supported in a manner as abovementioned, even if the blade is expanded or shrunk in the directions of the depth and the height due to change of the temperature, both can be absorbed by elastic operation of the plate spring 36 and sliding surface operation of the surface contact. |
