Abstract
It is possible to provide a sliding bearing that can obtain a friction reduction effect, and can suppress the total amount of outflow oil. A manufacturing method of the present invention is a method of manufacturing a sliding bearing (1) in which half members (2, 2) are arranged in a vertical arrangement, the half members (2, 2) being obtained by dividing a cylinder into two parts along a line parallel with the axial direction and having a metal layer (21) and a lining layer (22) provided on the inner circumferential surface of the metal layer (21), the manufacturing method comprising: a groove configuration step (S30) (first step) of providing a groove (3) in an axial end portion of the half member (2) on the lower side, the groove (3) extending in the circumferential direction on a downstream side in a rotation direction, wherein in the groove configuration step (S30), the depth (d) of the groove (3) is set smaller than the result of subtracting the sum of the tolerance (a1) of the thickness of the lining layer (22) and the tolerance (a2) of the depth of the groove (3) from the thickness (h1) of the lining layer (22).
