Claims

[Claims for Utility Model Registration] A turbine wheel, a compressor wheel fixed to a rotating shaft coaxial with the turbine wheel to be driven by the turbine wheel,
A sealing means is provided between a thrust metal that regulates the axial position of the rotating shaft and a rotating shaft insertion hole in a back plate on the compressor wheel side that is fitted onto the rotating shaft so as to be able to come into sliding contact with the thrust metal. and a shielding plate that is interposed between the inner surface of the back plate and the thrust metal and has an opening surrounding the bushing to capture lubricating oil scattered from the thrust metal. In the turbocharger, the shielding plate is composed of a plurality of plates arranged in series in the axial direction with a certain gap, and a groove is formed in an outer circumferential surface portion of the bushing located inside the inner surface of the back plate in the axial direction. A supercharger characterized by being surrounded by.
