Abstract: A resin coating layer has a shape line that indicates the shape of a surface and is divided by virtual straight lines parallel to the X axis and setting an area of recessed sections that protrudes below the virtual straight lines and an area of protruding sections that protrudes above the virtual straight lines. A virtual straight line at a position at which the area totals for the area of recessed sections and the area of protruding sections are equal is defined as the average line for unevenness. Areas that protrude downwards from this average line for unevenness are defined as recessed sections and areas that protrude above this average line for unevenness are defined as protruding sections. The average area Sa for one recessed section is 4-120 μm2 and the number M of recessed sections between two points having a distance of 1 mm therebetween is 3-20.

Abstract: The invention provides a thrust bearing, including a pair of half thrust bearings. 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.
