PROBLEM TO BE SOLVED: To obtain an excellent having dimensional accuracy, slidingly movable characteristics, heat resistance, rigidity or the like by blending a specific quantity of an inorganic filler containing a specific quantity of potassium titanate fiber and a specific quantity of polyolefine powder with thermosetting resin. SOLUTION: 50 to 600 pts.wt. of an inorganic filler containing 2 to 35 pts.wt. of potassium titanate fiber and 2 to 20 pts.wt. of polyolefine (polyethylene) powder having a particle diameter not more than 200μm are blended with 100 pts.wt. of thermosetting resin composed of unsaturated polyester resin, vinyl easter resin or a mixture of these. 10 to 60 pts.wt. of a low contactive agent is also blended with 100 pts.wt. of the thermosetting resin. Therefore, the excellent dimensional accuracy is obtained, and a frictional coefficient is reduced, and a frictional sound by meshing of gears, the so-called 'Chattering' is not produced even in use under nonlubrication, and excellent sliding performance is obtained, and excellent heat resistance and rigidity can be obtained.
