PROBLEM TO BE SOLVED: To suppress a leakage oil amount from a half-split bearing compared to conventional ones.SOLUTION: A half-split bearing 1 is an upper side half-split bearing that abuts on a lower side half-split bearing mating therewith, and forms a cylindrical bearing housing a shaft to the side of an inner peripheral surface as a whole. The half-split bearing 1 has: connection surfaces 11, 12 abutting on the connection surface of the lower side half-split bearing; a first region where a groove is formed from the connection surface 11 of an upstream side in a rotational direction of the shaft along the circumferential direction of an inner peripheral surface 13; and second region where a groove is not formed on a downstream side in the rotational direction with respect to the first region.SELECTED DRAWING: Figure 2 |
