Abstract
This half thrust bearing having a half-ring shape has: a sliding surface for receiving force in the axial direction; a back surface opposed to the sliding surface; and a resin covering layer on the sliding surface. The half thrust bearing is characterized in that the thickness of the resin covering layer is greatest at the circumferential central part of the half thrust bearing, and becomes lesser toward both circumferential ends of the half thrust bearing. The present invention also pertains to a thrust bearing, a bearing device, and an internal combustion engine.
