PROBLEM TO BE SOLVED: To provide a slide bearing capable of attaining a friction reduction effect and restricting a total sum of flow-out oil amount.SOLUTION: The present invention relates to a slide bearing 1 in which halved members 2, 2 divided into two in parallel with an axial direction of a cylinder are arranged above and below, an axial end of the lower halved member 2 is provided with fine grooves 3 in a circumferential direction, a circumferential edge part 2a outside the axial direction of the fine grooves 3 is provided with a concave part 2b, a length of the concave part 2b in its circumferential direction becomes shorter than the length of the fine grooves 3. In addition, the concave part 2b is formed in such a way that an upstream side end part 2c in a rotating direction is set at the same position as that of the upstream side end part 3b in a rotating direction of the fine groove 3. In addition, the concave part 2b is formed in such a way that a downstream side end part 2d in a rotating direction is set at a position of the upstream side than that of the central part of the fine grooves 3 in a circumferential direction (a bearing angle ω is 2ω). |
