Abstract
Resin composition and precision sliding parts are proposed. The resin composition includes a modified polyphenylene ether resin as a main component, a fibrous reinforcing agent, and a solid lubricant comprising tetrafluoroethyelene and graphite in the amount of 2-30 volume %. The modified polyphenylene ether resin is prepared by blending a polystyrene-family resin with a polyphenylele ether resin. The ratio of the tetrafluoroethylene resin and the graphite is 1:1 to 1:5. The fibrous reinforcing agent is glass fiber or carbon fiber. The fibrous reinforcing material is orientated such that the angle of fiber axis is not more than 30 degrees with respect to the sliding surface. The fibrous reinforcing material is a fibrous reinforcing material having a fiber diameter of 10 &mgr;m or less.
