Abstract
A connecting rod bearing is constituted of a pair of semi-cylindrical bearings I and II. In a state in which the semi-cylindrical bearings are assembled into a cylindrical shape, along two contact surfaces C of circumferential end surfaces, first axial oil grooves E are formed to be located at a central portion in a bearing width direction, and second axial oil grooves F are formed to be located at both sides in the bearing width direction of each of the first axial oil grooves E. One of the first axial oil grooves E and two of the second axial oil grooves F are in relation to communicate with each other. The first axial oil groove E is formed in the range of the wall thickness decreasing region surface A.
