Abstract: A bearing device includes: a journal part, a main bearing, a cylinder block, and a bearing cap. One half bearing held by the cylinder block includes: a first circumferential oil groove and a second circumferential oil groove being formed at positions opposite to an inlet of an oil passage of the journal part; a separation part separating the first circumferential oil groove and the second circumferential oil groove; and a first oil hole and a second oil hole respectively penetrating from the first circumferential oil groove and the second circumferential oil groove to an outer circumferential surface. The cylinder block includes an oil distribution passage which is formed so as to extend across both the first oil hole and the second oil hole of the one half bearing.

Abstract: A half thrust bearing having a semicircular ring shape for receiving an axial force of a crankshaft of an internal combustion engine is provided. The half thrust bearing includes thrust reliefs formed adjacently to end surfaces on both sides in a circumferential direction on a slide surface side which receives the axial force so that wall thicknesses become thinner toward the end surfaces. The thrust relief on a rear side in a rotational direction of the crankshaft or both thrust reliefs are formed so that a length of the thrust relief in an inner end portion in a radial direction of the half thrust bearing is longer than a length of the thrust relief in an outer end portion in the radial direction of the half thrust bearing.
