PURPOSE:To prevent a nozzle diaphgragm from floating when an upper half casing is lifted by arranging a gap adjusting screw in a support bar where the ends of the bar are inserted into a notch made on a junction surface of a lower half casing and into another notch made on the nozzle diaphragm. CONSTITUTION:A support bar 13 is installed in such a manner that one end of the bar is inserted into a notch 16 made on a horizontal junction surface of a lower half casing 1b, and another end into another notch 17 made on the lower half nozzle diaphragm 3b. And screw hole 21 is drilled out at the side end section of the notch 17 of the support bar 13 allowing a gap adjusting screw 22 to be screwed in the screw hole 21. This configuration can prevent the nozzle diaphragm 3a and 3b from floating when the upper half casing 1z is lifted. |
