Abstract
An object of the present invention is to provide a sliding member which can slide for a longer period of time even in a dry state. In the present invention, sliding layersare provided on the surfaces of a base material, and the sliding layercontains polybenzimidazole (PBI) and 1 to 70 vol % of a solid lubricant. Since PBI, which is a thermoplastic resin, has higher heat resistance and also has higher material strength than PAI, PI, and EP, which are the conventionally used thermosetting resins, the wear resistance and the anti-seizure property can be improved and a decrease in material strength caused by high-temperature atmosphere, heat generation at the time of sliding, etc. can be restrained. Furthermore, the initial conformability can be improved because of high elongation percentage. Also, since the sliding layer contains the solid lubricant, the coefficient of friction can be decreased, and hence the anti-seizure property can be enhanced.
