とを特徴とする可変ノズル付過給機。 A plurality of rotatable variable nozzle vanes are arranged concentrically with respect to the axis of the supercharger in the exhaust gas passage on the turbine side of the supercharger, and the shaft portion of the variable nozzle vanes is connected to the same number of variable nozzle vanes as the variable nozzle vanes of the supercharger. The variable nozzle vane is rotatably supported by a bush disposed concentrically with respect to the axis of the variable nozzle vane, and the variable nozzle vane is rotated by rotating the shaft part at the end of the shaft part protruding outward from the bush. In a supercharger with a variable nozzle in which link members of a link mechanism are connected, the bush is made to protrude beyond a housing that holds the bush on the opposite side to the variable nozzle vane, and the bush is connected to each link member of the link mechanism, and the bush is connected to each link member of the link mechanism. A ring-shaped member for simultaneously actuating members is partially, but not entirely, disposed in the protruding portions of at least three of the plurality of bushes disposed concentrically with respect to the axis of the supercharger. A supercharger with a variable nozzle, characterized in that the protrusion is supported in common and slidably on each outer circumferential surface of the protrusion.
