Abstract
Provided is a semi-cylindrical shaped half bearing. The half bearing has an inner surface forming a sliding surface. The sliding surface includes a plurality of recesses. Each recess has a smooth recess surface recessed from the sliding surface toward an outer diameter side of the half bearing. The recess surface forms a convex curve toward the outer diameter side of the half bearing in a cross-sectional view in any direction perpendicular to the sliding surface. The recess surface includes a plurality of circumferential grooves. The circumferential grooves are recessed from the recess surface toward the outer diameter side of the half bearing. The circumferential grooves extend along a circumferential direction of the half bearing so that smooth surfaces and the circumferential grooves are alternately arranged on the recess surface.
