Abstract
A turbocharger includes a semi-floating metal. The semi-floating metal is provided with a supply opening configured to supply oil to an inner bearing section. The turbocharger is provided with: an oil supply path which extends from inside of a bearing housing to the supply opening, and feeds the oil to be supplied to the inner bearing section; a removal section which changes a flowing direction of the oil supplied from an upstream side to separate minute foreign matter in the oil; and a conveyance path and a retaining region which collect the minute foreign matter separated by the removal section so as to prevent the minute foreign matter from mixing again with the oil flowing toward the supply opening.
