PROBLEM TO BE SOLVED: To provide a bearing device with a slide bearing excellent in foreign matter dischargeability. SOLUTION: The slide bearing 4 is formed in a cylindrical shape by abutment of abutting surfaces 11A, 12A of a pair of halved bearings 11, 12. At the positions of the abutting surfaces 11A, 12A, a radial through-hole 7 is formed by being superimposed on a moving locus of an oil supply hole of a crank pin. Moreover, an axial foreign matter discharging groove 8 is formed on the outer peripheral surface of the sliding bearing 4 in communication with the through-hole 7. When the crank pin is rotated, a lubricating oil is directly supplied also to the through-hole 7 from the oil supply hole. Foreign matter included in the lubricating oil is discharged to the outside of the sliding bearing 4 via the foreign matter discharging groove 8 after passing through the through-hole 7.
