Abstract:
The present invention improves the drainability of lubricating oil. The present invention comprises: a rotating shaft ( 14 ); a journal bearing that is provided to the rotating shaft ( 14 ) and rotationally supports the rotating shaft ( 14 ); a bearing housing part that houses the journal bearing; and a drain oil space chamber ( 47 ) that acts as an oil drainage passage that communicates with the bearing housing part, is provided along the periphery of the rotating shaft ( 14 ), and is formed to open downward. Within a region that is in and above a horizontal plane H that passes through the center of the rotating shaft ( 14 ), the smallest cross-sectional area of the oil drainage passage in a radial-direction cross-section thereof is on the anterior side in the rotational direction of the rotating shaft ( 14 ) with respect to a vertical plane P that passes though the center (O) of the rotating shaft ( 14 ), and the largest cross-sectional area of the oil drainage passage in the radial-direction cross-section is on the posterior side in the rotational direction of the rotating shaft ( 14 ) with respect to the vertical plane that passes through the center (O) of the rotating shaft ( 14 ).

Claim (Index 25):
The bearing device according to  claim 14 ,\n wherein in the oil discharge passage, a cross-sectional area in the radial cross section is changed in a radial direction.
