Patent ID: 7509804

Claim:
A turbocharger with a variable nozzle comprising: a turbine impeller rotationally driven by an exhaust gas; a compressor impeller rotationally driven by the turbine impeller so as to compress an air; a shaft coupling the turbine impeller and the compressor impeller; a bearing housing rotatably supporting the shaft; a turbine housing accommodating the turbine impeller in an inner portion thereof; and a variable nozzle mechanism, provided in a compressor impeller side in a radial-direction outer side of the turbine impeller, for adjusting a flow rate of an exhaust gas directed to the turbine impeller, wherein the bearing housing has a radially expanded portion that extends to a radial-direction outer side to be coupled to the turbine housing at a radial-direction outer side portion thereof such that the variable nozzle mechanism is accommodated between the turbine housing and the radially expanded portion, and a heat shield plate is provided between the variable nozzle mechanism and the radially expanded portion for preventing a heat transmission between the variable nozzle mechanism and the radially expanded portion.
