Abstract
A resin composition for a sliding member is difficult to peel and whose component is difficult to elute when the resin composition is formed as a film on a surface of a mechanical part, even though the resin composition is used in environment where the sliding member contacts lubricating oil containing a sulfur-based additive or in atmosphere containing a sulfur-based compound. A resin composition for a sliding member to be used for a mechanical part having a surface thereof formed of said sliding member. The resin composition contains polyamide-imide resin having an elongation percentage of 60% to 120%, fullerene, and at least one disulfide selected from among molybdenum disulfide and tungsten disulfide. 0.1 to 10 vol % of the fullerene and 0.5 to 20 vol % of the disulfide are contained in an entirety of the resin composition.
