A turbocharger comprises a shaft connecting a turbine wheel, which is disposed in a turbine housing, to an impeller wheel. Between the two is a bearing system having a bearing housing and bearings for the shaft disposed therein. The shaft is fitted with at least one heat insulation between the turbine wheel and the bearing system, of which the heat conductivity is lower than that of the portions of the shaft which are adjoining said insulation and which hampers heat transmission through the shaft.
