There is provided a slide bearing for a crankshaft of an internal combustion engine, having a pair of half bearings combined with each other to form the slide bearing, and a crush relief formed in each end portion region in a circumferential direction of an inner peripheral surface of each half bearing by reducing a bearing wall thickness over an entire width in an axial direction of the half bearing, wherein a relief depth RD which is a reduction amount of the bearing wall thickness of the crush relief is maximum at each end portion in the circumferential direction of the half bearing, and gradually decreases toward a center in the circumferential direction, and the relief depth RD is maximum in a center in an axial direction of the half bearing, and gradually decreases toward both end portions in the axial direction. |
