Abstract
A half bearing includes a bearing body having a semi-circular tube shape with mating surfaces and that come into contact with a half bearing, and an oil groove that is provided on the sliding surface and extends in a rotational direction of a shaft. The oil groove has a curved shape in a cross section parallel to the shaft direction, the width of the oil groove is uniform in a range of at least ±30° in a cross section orthogonal to the shaft direction, and the width of the oil groove is smaller than the width in the range, in at least a region on the downstream side in the rotational direction among regions outside of the range.
