Abstract
A tilting pad bearing is provided that can reduce an amount of oil leaking from the side edges of a sliding surface of a pad, thereby reducing an amount of oil to be fed onto the sliding surface of the pad. The tilting pad bearing includes journal pads arranged in a circumferential direction of a rotating shaft, and a bearing housing for carrying the journal pads in a tiltable manner via associated pivots. Lubricating oil is fed to a sliding surface of the journal pad via an oil-feeding hole formed in the journal pad. The sliding surface of the journal pad has a portion formed so that the portion has an axial width that gradually increases, as the axial width approaches the circumferential downstream side of the rotating shaft, from an oil-feed start position.
