Claim:
A turbocharger comprising: a turbine wheel including a center hole coaxial with a rotation center thereof, the center hole including a shaft support portion; a turbine shaft inserted through the center hole, one end of the turbine shaft being secured to the shaft support portion; a bearing device that rotatably supports the turbine shaft; a bearing housing that houses the bearing device with the turbine wheel being exposed at one end surface in an axial direction thereof; a turbine housing secured to an end surface of the bearing housing in the axial direction to enclose the turbine wheel; and a heat shield member, wherein a cylindrical clearance is formed between the center hole and an outer circumferential surface of the turbine shaft, the clearance opening toward the bearing housing at one end thereof, and wherein the heat shield member includes a main body portion disposed between an end of the bearing housing in the axial direction and the turbine wheel to serve as a heat shield therebetween, and a cylindrical portion integrally formed with the main body portion so as to extend from the main body portion in the cylindrical clearance so as to cover an outside of the turbine shaft to serve as a heat shield between the turbine shaft and the turbine wheel.
