摘要

There is provided a turbocharger bearing housing which is capable of reducing the weight thereof. A bearing housing of a turbocharger contains a shaft connecting a turbine and a compressor, and turnably supports the shaft. The bearing housing of the turbocharger is divided into a turbine-side housing disposed at a turbine side and a compressor-side housing disposed at a compressor side. The compressor-side housing is formed of an aluminum-based material.
