Abstract
A turbocharger includes a turbine housing and a wastegate valve. The turbine housing defines two bypass passages. The wastegate valve opens and closes the two bypass passages. The turbine housing has a valve seat surface that is a flat surface that the wastegate valve contacts. The wastegate valve has a valve surface and a depression. The valve surface is a flat surface that faces the valve seat surface when the wastegate valve is in a closed state. The depression is depressed from the valve surface. The depression is located at a portion that faces a region located between openings of the two bypass passages when the wastegate valve is in the closed state.
