A slide bearing, in which halved members, made by dividing a cylinder parallel to the axial direction are disposed vertically, includes a groove circumferentially provided at the axial end of a lower halved member and a recess provided on an axially outer periphery of the groove, where a circumferential length of the recess is formed to be shorter than a length of the groove. The recess is formed such that its upstream end in the axial rotation direction aligns with an upstream end in the rotation direction of the groove. The recess is formed such that its downstream end in the rotation direction is located upstream relative to the circumferential center of the groove.
