接続部にはノブ挿入用の溝穴を設ける。In FIG. 1, the structure of the variable nozzle expansion turbine is constructed by connecting the inside J of the expansion turbine with a rigid air cylinder 2 that generates linear rod motion. In FIG. 2, a nozzle drive device [3 connects a nozzle 5 to a nozzle fixing ring 4 with a fixing pin 6, and a movable pin 7 connects the nozzle to a movable ring 8 with a fixed pin and a movable pin. By rotating this co-moving ring 8,
The angle of the nozzle 5 is changed via the movable pin 7 to change the nozzle area. The movable ring 8 has an arc-shaped knob on the outer periphery of the movable ring and a rod (1) 9 in order to convert the linear motion of the rod (]) 9 into rotational motion of the movable ring.
A slot for inserting the knob is provided in the connection part.
