ル構造。 In a nozzle disposed upstream of the rotor blade inlet side of an axial flow turbine, the nozzle includes a leading edge nozzle ring that holds a leading edge nozzle vane, a trailing edge nozzle ring that holds a trailing edge nozzle vane, and a trailing edge side or leading edge side nozzle ring that holds a trailing edge nozzle vane. The leading edge side nozzle ring and the trailing edge side nozzle ring have nozzle vanes of both rings joined at a predetermined position to form one airfoil shape, and a driving device for driving the nozzle rings of the leading edge side nozzle ring and the trailing edge side nozzle ring. A variable nozzle structure for an axial flow turbine, characterized in that the variable nozzle structure is arranged so as to be relatively movable in the circumferential direction.
