A sliding bearing 4 is formed in the shape of a cylinder by joining joining surfaces 11A and 12A of a pair of half bearings 11 and 12 together. A through hole 7 is formed in the position of the joining surfaces 11A and 12A in such a manner that the through hole 7 coincides with the trajectory of movement of a lubrication hole 3A in a crankpin 3. A foreign particle discharge groove 8 is formed in an outer circumferential surface of the sliding bearing 4 along the axial direction leading from the through hole 7. When the crankpin 3 is rotated, a lubricant is directly supplied into the through hole 7 as well through the lubrication hole 3A. Foreign particles 15 contained in the lubricant pass through the through hole 7 and are then discharged to the outside the sliding bearing 4 through the foreign particle discharge groove 8. Thus, a sliding bearing 4 that can smoothly discharge foreign particles can be provided. |
