<P>PROBLEM TO BE SOLVED: To provide a plain bearing for an internal combustion engine assuring a low friction coefficient and excellent non-seizure characteristics while maintaining fatigue resistance. <P>SOLUTION: The plain bearing for the internal combustion engine comprises a slide layer 6 including a lubricant outer layer 5 in which a solid lubricant is contained. The lubricant outer layer 5 contains an element which is contained in the solid lubricant at a maximum concentration of not less than 5 mass% in the lubricant outer layer, at least a particle 4 of the solid lubricant structured by gathering a plurality of primary particles exists on a surface of the lubricant outer layer 5, and the solid lubricant gathered particle exists wherein a long side of the solid lubricant particle 4 is equal to or longer than 20 μm and shorter than 100 μm in a surface visual field of the lubricant outer layer 5. <P>COPYRIGHT: (C)2007,JPO&INPIT |
