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.

Abstract: A sliding member of the present embodiment includes a bearing alloy layer and a coating layer provided on a sliding surface side thereof. The coating layer has a resin binder with sulfide particles dispersed therein. A covering portion is provided over specific particles and is made of metal oxide comprising the same metal element as a metal element constituting the sulfide particles. When measured by an X-ray photoelectron spectroscopy and an X-ray diffraction method, a ratio of a peak height of the metal oxide to a peak height of metal sulfide by the X-ray photoelectron spectroscopy is from 0.10 to 0.50, and a ratio of the peak height of the metal oxide to the peak height of the metal sulfide by the X-ray diffraction method is 0.10 or less.
