<p>PROBLEM TO BE SOLVED: To improve the performance of a turbine, to reduce the number of pieces of components of a variable nozzle driving member and to provide a variable capacity turbine with the low cost. SOLUTION: Plural variable nozzles 2b provided on a gas inlet passage to a moving blade 7, are fixed to a circular rotary nozzle ring 31b along a circumferential direction thereof, plural fixed nozzles 2a are fixed along a circumferential direction of a fixed nozzle ring, the variable nozzles 2b and the fixed nozzles 2a are alternately arranged in the circumferential direction, and the rotary nozzle ring 31b is rotated, to change an area of a nozzle throat part between the variable nozzle 2b and the fixed nozzle 2a.</p> |
