Abstract:
The purpose of the invention is to reduce bearing loss due to lubricating oil. This invention comprises: a rotary shaft ( 14 ); a journal bearing ( 22 ) that is provided to the rotary shaft ( 14 ) and that rotatably supports the rotary shaft ( 14 ); a flange part ( 17 b ) having an opposing surface part ( 17 bb ) that is arranged so as to oppose a side surface part ( 22 d ) of the journal bearing ( 22 ) with a gap (D) therebetween in the axial direction in which the rotary shaft ( 14 ) extends; and a recess part ( 22 e ) provided in the side surface part ( 22 d ) or the opposing surface part ( 17 bb ). In the projected area of the journal bearing ( 22 ) in the axial direction, the area of a section including the recess part ( 22 e ) and not forming the gap (D) is larger than the area in which the side surface part ( 22 d ) and the opposing surface part ( 17 bb ) form the gap (D).

Claim (Index 6):
An exhaust turbine turbocharger comprising:\n a turbine; a compressor; a rotating shaft which coaxially connects the turbine and the compressor to each other; a housing in which the turbine, the compressor, and the rotating shaft are accommodated; a journal bearing which is provided on the rotating shaft, is accommodated in the housing, and rotatably supports the rotating shaft; a disk member which is provided on the rotating shaft and has a facing portion which is disposed so as to face a side surface portion of the journal bearing with a gap therebetween in an axial direction in which the rotating shaft extends; a recessed portion which is provided in the side surface portion or the facing portion; and the bearing device according to  claim 1 .
