Beschreibung
Zusammenfassung:	A journal bearing includes: a carrier ring; a plurality of bearing pads disposed on a radially inner side of a lower half region of the carrier ring; a pair of side plates disposed on both sides of the plurality of bearing pads with respect to an axial direction of the rotor shaft; and at least one oil-supply unit for supplying lubricant oil to the plurality of bearing pads. From among the at least one oil-supply unit, a first oil-supply unit disposed on a downstream side of a most downstream pad positioned most downstream of the plurality of bearing pads is configured to supply the lubricant oil toward a region below a corner portion of the most downstream pad, of a trailing edge surface of the most downstream pad, the corner portion being formed by an intersection between a pad surface of the most downstream pad and the trailing edge surface.
