ヤ。 A nozzle flow path wall consisting of parallel walls is formed at an inlet to the turbine rotor, a plurality of nozzle vanes rotatable around an axis perpendicular to the nozzle flow path wall are provided between the nozzle flow path walls, and the nozzle vane In a turbocharger with a variable nozzle that changes the speed of flow of exhaust gas from an internal combustion engine to the turbine rotor by changing the rotation angle of the nozzle vane, as the width direction of both sides of the nozzle vane increases away from the rotation axis of the nozzle vane. A turbocharger with a variable nozzle, characterized in that the nozzle vane is formed in a tapered shape so that the width thereof is reduced, and the corners of the nozzle vane in the thickness direction on both sides in the width direction are formed in an R shape.
