Abstract: A turbocharger includes a rolling bearing including at least one rolling element for rotatably supporting a rotational shaft, a bearing support cylinder located on a radially outer side relative to the rolling bearing, for supporting the rolling bearing, and a housing located on the radially outer side relative to the bearing support cylinder, for covering a circumference of the bearing support cylinder. Between an outer circumferential surface of the bearing support cylinder and an inner circumferential surface of the housing, a gap for forming an oil film by inflow of lubricant oil is provided. At least one of the outer circumferential surface of the bearing support cylinder and the inner circumferential surface of the housing includes an oil film holding portion for suppressing outflow of the lubricant oil from the gap. The oil film holding portion is a protrusion disposed on the outer circumferential surface of the bearing support cylinder, or a recess or the protrusion disposed on the inner circumferential surface of the housing.
