Abstract
A thrust bearing is equipped with a resin coating applied to the surface of a base material. Lattice-shaped discharge grooves are formed in the surface of the thrust bearing, and planer protrusions having a square shape or the like are formed at the adjacent positions thereof. Each corner part of each planer protrusion form a sliding surface that slides with respect to a counterpart member. Contaminants such as wear particles that have infiltrated between the counterpart member and the sliding surface fail into the discharge grooves and then are discharged outside of the sliding surface. The chamfering of each corner part to a rounded shape prevents the contaminants from accumulating in the discharge grooves, thus preventing the contaminants from biting into the planer protrusions.
