A turbocharger comprising: a housing a turbine wheel constituting a turbine; a compressor wheel constituting a compressor; a rotating shaft connecting the turbine wheel and the compressor wheel to each other, the housing housings at least the rotating shaft; and a semi-floating metal bearing also housed in the housing, forming a fluid bearing between the rotating shaft and the housing, and rotatably supporting the rotating shaft, wherein the semi-floating metal bearing is fixed to the housing by a pin, an oil reservoir space is formed between the housing and the semi floating metal bearing to temporarily retain oil, the housing is provided with an upstream side first supply opening configured to supply oil to the oil reservoir space, and the semi-floating metal bearing is provided with a second supply opening (61c, 61ca) configured to supply oil in the oil reservoir space to an inner bearing section formed between the semi-floating metal bearing and the rotating shaft, an oil supply path extending from inside of the housing to the second supply opening (61c, 61ca) via the first supply opening is formed to feed oil to be supplied to the inner bearing section and is provided with a removal section configured to change a flowing direction of the oil supplied from an upstream side to separate minute foreign matter in the oil, wherein the first supply opening and the second supply opening (61c, 61ca) are located at different positions without being overlapped to each other in an axial direction of the rotating shaft, characterised in that the removal section comprises a separation wall surface formed in an outer peripheral surface of the semi-floating metal bearing, and is opposed to the first supply opening and to a flow of the oil supplied from the upstream side, an outer diameter of the outer peripheral surface of the semi-floating metal bearing is constant from a position opposed to the first supply opening to the second supply opening (61c, 61ca) and an inner diameter of a housing inner wall is constant from the first supply opening to a position opposed to the second supply opening (61c, 61ca); and a collecting section (TA, SA) is provided to collect the minute foreign matter separated by the separation wall surface so as to prevent the minute foreign matter from mixing again with the oil flowing toward the second supply opening (61c, 61ca). a housing a turbine wheel constituting a turbine; a compressor wheel constituting a compressor; a rotating shaft connecting the turbine wheel and the compressor wheel to each other, the housing housings at least the rotating shaft; and a semi-floating metal bearing also housed in the housing, forming a fluid bearing between the rotating shaft and the housing, and rotatably supporting the rotating shaft, wherein the semi-floating metal bearing is fixed to the housing by a pin, an oil reservoir space is formed between the housing and the semi floating metal bearing to temporarily retain oil, the housing is provided with an upstream side first supply opening configured to supply oil to the oil reservoir space, and the semi-floating metal bearing is provided with a second supply opening (61c, 61ca) configured to supply oil in the oil reservoir space to an inner bearing section formed between the semi-floating metal bearing and the rotating shaft, an oil supply path extending from inside of the housing to the second supply opening (61c, 61ca) via the first supply opening is formed to feed oil to be supplied to the inner bearing section and is provided with a removal section configured to change a flowing direction of the oil supplied from an upstream side to separate minute foreign matter in the oil, wherein the first supply opening and the second supply opening (61c, 61ca) are located at different positions without being overlapped to each other in an axial direction of the rotating shaft, characterised in that the removal section comprises a separation wall surface formed in an outer peripheral surface of the semi-floating metal bearing, and is opposed to the first supply opening and to a flow of the oil supplied from the upstream side, an outer diameter of the outer peripheral surface of the semi-floating metal bearing is constant from a position opposed to the first supply opening to the second supply opening (61c, 61ca) and an inner diameter of a housing inner wall is constant from the first supply opening to a position opposed to the second supply opening (61c, 61ca); and a collecting section (TA, SA) is provided to collect the minute foreign matter separated by the separation wall surface so as to prevent the minute foreign matter from mixing again with the oil flowing toward the second supply opening (61c, 61ca).
