Beschreibung
Zusammenfassung:	A turbocharger according to an embodiment of the present invention includes a rotating shaft, a compressor, a turbine, a compressor-side floating bearing and a turbine-side floating bearing that rotatably support the rotating shaft, and a bearing housing that houses the compressor-side floating bearing and the turbine-side floating bearing, the bearing housing being internally provided with a turbine-side oil feeding passage through which oil to be fed to the turbine-side floating bearing flows and a compressor-side oil feeding passage through which oil to be fed to the compressor-side floating bearing flows. A ratio of an oil feeding pressure for oil at an outlet of the compressor-side oil feeding passage to an oil feeding pressure for oil at an outlet of the turbine-side oil feeding passage is configured to be higher than 1.0 and lower than 1.5.
