A turbocharger includes a main housing (1) for housing a turbine rotor (2) and a compressor impeller (4). An independent bearing box (23) is provided in the main housing (1). The main housing (1) is comprised of a turbine housing (3) and a compressor housing (5). A rotating shaft (7) connecting the turbine rotor (2) with the compressor impeller (4) is supported by a semi-float bearing metal (24) which is held in the bearing box (23) by a retaining pin (25). A hard insert ring (42) is fitted in the bearing metal (24) to form a retaining pin receiver.
