Abstract: A turbocharger includes a turbine housing formed with openings of twin scrolls such that the openings are arranged to be adjacent to each other in an axial direction of a turbine. A fixed sleeve is fixedly disposed within the turbine housing such that an inner surface of the fixed sleeve defines a basic passage as a passage for exhaust gas emerging from the turbine while defining a bypass passage outside the basic passage as a passage for exhaust gas bypassing the turbine. A sliding ring can slide in the axial direction of the turbine between the fixed sleeve and the turbine housing, to control a state in which exhaust gas passing through the twin scrolls is supplied to the turbine and a state in which the exhaust gas passing through the twin scrolls is discharged into the bypass passage while bypassing the turbine.
