To provide a sliding bearing capable of providing excellent lubricating effect, hardly abraded by restraining metallic contact even if high bearing pressure is received, and capable of exhibiting the smooth bearing action over a long period, by sufficiently supplying lubricating oil stored in a plurality of grooves extending in the direction crossing with the peripheral direction, to the whole area of a sliding surface adjacent to its groove in response to the rotation of a shaft.
An inclined groove 12 is formed on an inner peripheral surface 10 of a beating 1 under a condition of the following (A)-(D): (A) a range of 10-60 degrees in the direction orthogonal to the peripheral direction, (B) a groove width B in the peripheral direction is set to 0.5-5 mm, (C) a width A in the peripheral direction of the sliding surface 14 being a surface of a crest part between the adjacent grooves is set to 1-7 mm, and (D) the ratio A/B of the width A to the groove width B of the sliding surface is set to 0.5-5.0, and an inner peripheral groove 15 and an outer peripheral groove 16 communicating with the inclined groove 12, are also formed in the bearing 1 in a pair state, and a through-hole 17 is formed for penetrating through the inner peripheral groove 15 and the outer peripheral groove 16.
