Abstract
A thrust bearing including a ring-like form plate body, and a plurality of rib members provided on the ring-like form plate body of the thrust bearing. Such a plurality of rib members may be provided on a thrust runner. The rib members cause a difference in load deformation amount in a circumferential direction according to thrust load and generate a wedge-shaped form clearance between a sliding face of the thrust bearing and a sliding face of the thrust runner. Since the wedge-shaped form clearance is formed by utilizing the load deformation, even when the thrust load becomes large, the wedge-shaped form clearance does not become narrow. The occurrence of dynamic pressure by the wedge effect and the formation of a water film can be assured, and the temperature increase between the sliding face of the thrust runner and the sliding face of the thrust bearing can be restrained.
