PROBLEM TO BE SOLVED: To provide a radial sliding bearing capable of effectively improving a support load by oil film reaction force.SOLUTION: In a radial sliding bearing 1 pivotally supporting a crankshaft 2 by a bearing metal 10, an oil supply groove 25 for supplying lubrication oil is open on the inner circumferential face 11a of an upper bearing 11; and on the inner circumferential face 11a of the upper bearing 11, two first projections 14 extending in a circumferential direction at both axial ends and two second projections 15 disposed at the opening edge of the oil supply groove 25, are formed to increase oil film pressure. |
