An inner surface of each first supporting hole of a shroud ring has on both sides in the axial direction of a turbine impeller two first bearing portions by which first nozzle shaft is rotatably supported. An inner surface of each second supporting hole of a nozzle ring has a second bearing portion by which a second nozzle shaft is rotatably supported. The fitting clearance between the second bearing portion and the second nozzle shaft is set larger than the fitting clearance between each of the first bearing portions and the first nozzle shaft.
