PROBLEM TO BE SOLVED: To provide an unsaturated polyester resin composition which maintains the excellent characteristics, such as dimensional accuracy, mechanical strength, moldability, heat resistance, and flame retardancy, of conventional unsaturated polyester molding materials and has high sliding characteristics and high abra sion resistance. SOLUTION: This sliding unsaturated polyester resin composition is characterized by comprising 50 to 600 pts.wt. of a filler, 5 to 20 pts.wt. of an organic fluorocompound, and 100 pts.wt. of the combination of a cross-linking agent with an unsaturated polyester in which the rate of the total amount of cyclic skeleton-having polyhydric alcohol residues and cyclic skeleton-having saturated/ unsaturated polybasic acid residues to the total amount of polyhydric alcohol residues and saturated/unsaturated polybasic acid residues is <=8 mol.%. |
