Abstract
A half bearing includes circumferentially extending first and second grooves on the inner circumferential surface. The circumferential end of the first groove, on the rotational upstream side of the shaft, has an inclination angle θ1 of 135° formed by: a first imaginary line connecting the inner circumferential surface end of a mating surface and the origin of an outer circumferential surface; and a second imaginary line connecting the end of the first groove and the origin of the outer circumferential surface. The circumferential end of the second groove, on the rotational upstream side of the shaft, has an inclination angle θ2 of 135° formed by: a first imaginary line connecting the inner circumferential surface end of the mating surface and the origin of the inner circumferential surface; and a third imaginary line connecting the end of the second groove and the origin of the outer circumferential surface.
