PROBLEM TO BE SOLVED: To provide a nozzle diaphragm connected body which has a water content flow passage inside and in which water content retention in the water content flow passage is restricted.SOLUTION: A nozzle diaphragm connected body of an embodiment includes a plurality of nozzle diaphragm stages, the water content flow passage, a positioning pin, and a water content discharge hole. The pluralities of nozzle diaphragm stages are connected to each other. The water content flow passage is formed between the nozzle diaphragm stages adjacent to each other so as to extend in a circumferential direction. The positioning pin is arranged between the nozzle diaphragm stages adjacent to each other so as to extend in a radial direction. Also the positioning pin has a small-diameter part which has smaller diameter than that of other parts and is positioned on an overlapping part with the water content flow passage. The water content discharge hole connects between the water content flow passage and the periphery of the plurality of nozzle diaphragm stages and discharges the water content in the water content flow passage to outside. |
