PROBLEM TO BE SOLVED: To provide a slide bearing which supports a shaft member with a wide surface while supplying a sufficient amount of lubrication oil to inner peripheral surfaces of semi-cylindrical bearings. ! SOLUTION: A cylindrical connecting rod bearing is formed by combining a pair of semi-cylindrical bearings (a lower side bearing 10 and an upper side bearing) and rotatably supports a crank pin. Each of the lower side bearing 10 and the upper side bearing includes: crash reliefs 11 respectively formed at both end parts of an inner peripheral surface; and an upstream side oil groove 12 which is formed along a circumferential direction at the upstream side of the inner peripheral surface when viewed in a rotation direction of the crank pin so as to be separated from the crash reliefs 11. !
