機。 An oblique gas flow formed between a turbine wheel in a turbine casing and a scroll-shaped gas flow path formed on the outer periphery of the turbine wheel so as to introduce the gas flow into the turbine wheel from an oblique direction. In the supercharger, the heat shield plate disposed between the turbine casing and the bearing casing is arranged such that the gas flow introduction passage forming surface of the heat shield plate is positioned obliquely in the introduction part. The gas flow introduction channel forming surface is set back from the gas flow introduction part by a required amount, and the inclination angle of the gas flow introduction channel forming surface is 15 degrees or less with respect to the gas inflow direction. A supercharger featuring:
