    Abstract: There is provided a half thrust bearing having a semicircular-ring shape for a crankshaft of an internal combustion engine, including a back metal layer and a bearing alloy layer having a slide surface on which thrust reliefs are formed adjacently to both circumferential end surfaces so that a wall thickness of the half thrust bearing becomes thinner from the slide surface toward the circumferential end surfaces. A thrust relief length L1 of each thrust relief extends over a circumferential angle θ1 from the circumferential end surface toward a circumferential central portion, and is constant between an inside end portion and an outside end portion in a radial direction of the half thrust bearing. A flat surface of each thrust relief includes a first region on the circumferential end surface side and a second region on the circumferential central portion side.

Each half thrust bearing includes a bearing alloy layer and a resin slide layer, or a back metal layer, a bearing alloy layer and a resin slide layer. The resin slide layer constitutes a slide surface receiving an axial force of a crankshaft. Each half thrust bearing include thrust reliefs formed adjacent to both circumferential end portions of the sliding surface so that a wall thickness is thinner toward the circumferential end surface. A thrust relief length at an inner end portion of the thrust relief positioned on a rear side of one of the half thrust bearings in a rotational direction is larger than a thrust relief length at an inner end portion of the thrust relief positioned on a front side of the other of the half thrust bearing in the rotational direction.
