Abstract
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 and configured to support a rotor shaft from below, and 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. Each of the side plates includes a first region including a circumferential range upstream of a first bearing pad positioned furthest upstream among the plurality of bearing pads, and a second region positioned upstream of the first region and has a larger distance between an inner peripheral surface of the side plate and an outer peripheral surface of the rotor shaft than that of the first region.
