Abstract
A turbocharger includes a turbine wheel having a center hole and a turbine shaft having one end secured on a small-diameter inner circumferential surface of the center hole. A large-diameter inner circumferential surface and a large diameter outer circumferential surface are formed to provide a cylindrical clearance opening toward a bearing housing between the center hole and the outer circumferential surface of the turbine shaft.
