Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a lubricating resin composition which is excellent in injection moldability and sliding properties, does not attack a mating material made of a soft metal and can cope with a mating material made of a soft to hard metal by mixing a molten fluororesin with carbon fibers and a liquid crystal polymer. SOLUTION: An example of the molten fluororesin is desirably at least one member selected from the group consisting of tetrafluoroethylene/ethylene copolymers, tetrafluoroethylene/perfluoroalkyl vinyl ether copolymers and tetrafluoroethylene/hexafluoropropylene copolymers. The liquid crystal polymer is more desirably a polymer comprising at least one type of repeating units represented by formulas I to III. This composition is more desirably one prepared by mixing 100 pts.vol. molten fluororesin with 5-40 pts.vol. carbon fibers and 2-30 pts.vol. liquid crystal polymer.
