Claims

[Claims for Utility Model Registration] An internal combustion engine that has a shaft with a compressor wheel and a turbine wheel arranged on both sides, and the shaft portion sandwiched between the wheels is directly supported by two spaced apart shaft bearings. In the turbocharger of an engine, the shaft is formed with the same diameter from the shaft part sandwiched between the shaft bearings to the compressor wheel fitting part, and the collar thrust and spacer seal arranged between the shaft bearing and compressor wheel are formed with the same diameter. A turbocharger characterized in that the compressor wheel is integrally combined with a compressor wheel and fitted onto the shaft, and the compressor wheel is locked at an end edge of the shaft.
