    • 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 member 1 constitutes a bearing having a cylindrical shape, an inner circumferential surface of which is a sliding layer 5 with an axis. In the sliding member 1, a porous layer 3 made of alloy material is formed on a surface of a metal base 2 and this porous layer 3 is covered by resin material 4 so that the sliding layer 5 is formed. In the sliding member 1, a particle size of metal powder 30 forming the porous layer 3 is within a range of 15 through 60 μm, preferably, about 25 through 45 μm. Further, in the sliding member 1, a thickness of the porous layer 3 is within a range of 0.06 through 0.1 mm and a thickness of the sliding layer 5 is within a range of 0.08 through 0.16 mm The thickness of the sliding layer 5 is set to be thicker on average than the thickness of the porous layer 3 so that the porous layer 3 is not exposed.
    • 提供通过抑制多孔层的任何暴露来改善耐咬合性并提高耐磨性和耐负荷性的滑动构件。 滑动构件1构成具有圆筒形状的轴承,其内周表面是具有轴的滑动层5。 在滑动构件1中,在金属基体2的表面上形成由合金材料制成的多孔层3,并且该多孔层3被树脂材料4覆盖,从而形成滑动层5。 在滑动构件1中,形成多孔层3的金属粉末30的粒径在15〜60μm的范围内,优选为25〜45μm左右。 此外,在滑动构件1中,多孔层3的厚度在0.06〜0.1mm的范围内,滑动层5的厚度在0.08〜0.16mm的范围内。设定滑动层5的厚度 平均地比多孔层3的厚度更厚,使得多孔层3不暴露。
