PROBLEM TO BE SOLVED: To miniaturize an exhaust driven supercharger of an internal combustion engine having: a turbine for expanding an exhaust gas flow of an engine of the internal combustion engine; and a compressor for compressing a supercharging air flow to be supplied to the engine of the internal combustion engine, wherein the turbine has a turbine rotor 11, the compressor has a compressor rotor 12, the turbine rotor 11 and the compressor rotor 12 are arranged on a common shaft 13, and a bearing housing 16 for supporting the shaft 13 is placed between the turbine rotor 11 and the compressor rotor 12. SOLUTION: At least one hydraulic machine 17 for taking out mechanical shaft horsepower from the exhaust driven supercharger in the so-called generator operation or supplying the mechanical shaft horsepower to the exhaust driven supercharger in the so-called engine operation, is integrally incorporated into the bearing housing 16 placed between the turbine rotor 11 and the compressor rotor 12.
