Abstract
A second nozzle shaft of each variable nozzle has an outer diameter smaller than that of a first nozzle shaft. The first nozzle shaft is integrally formed on a first side surface of each variable nozzle. A portion is provided on a second side surface of each variable nozzle. The portion encloses the second nozzle shaft, and can contact a second nozzle ring. An inner nozzle flange and an outer nozzle flange which can contact a first nozzle ring are integrally formed on base sides of the first nozzle shaft on a blade surface and a blade surface of each variable nozzle, respectively.
