A slide bearing for an internal combustion engine

摘要

A slide bearing for an internal combustion engine is provided. The slide bearing includes a metal layer 2 having an inner peripheral surface formed to extend along at least a part of a cylindrical shape, and a resin coating layer 3 formed on the inner peripheral surface of the metal layer 2. The inner peripheral surface of the metal layer 2 has annular or helical groove sections that extend in a generally circumferential direction of a cylindrical shape such that the inner peripheral surface has annular or helical protrusion sections which extend in the generally circumferential direction. The resin coating layer 3 is formed to match the shapes of the groove sections and the protrusion sections. t and Rpk satisfy the following relations: 1.0 μm ≤ t ≤ 5.0 μm; and 0.06 ≤ Rpk/t ≤ 5.04, where t is an average coating thickness of the resin coating layer 3 at positions different from crests of the protrusion sections; and Rpk is a reduced peak height of the resin coating layer 3.
