Abstract
To provide a sliding member that improves seizure resistance by restraining any exposure of the porous layer and improves abrasion resistance and load resistance. The sliding memberconstitutes a bearing having a cylindrical shape, an inner circumferential surface of which is a sliding layerwith an axis. In the sliding member, a porous layermade of alloy material is formed on a surface of a metal baseand this porous layeris covered by resin materialso that the sliding layeris formed. In the sliding member, a particle size of metal powderforming the porous layeris within a range of 15 through 60 μm, preferably, about 25 through 45 μm. Further, in the sliding member, a thickness of the porous layeris within a range of 0.06 through 0.1 mm and a thickness of the sliding layeris within a range of 0.08 through 0.16 mm The thickness of the sliding layeris set to be thicker on average than the thickness of the porous layerso that the porous layeris not exposed.
