PROBLEM TO BE SOLVED: To obtain the subject composition, excellent in sliding characteristics and further balance among heat resistance, mechanical characteristics and molding processability by compounding a resin composition comprising a rubber- containing graft copolymer and a vinylic copolymer having a specific structure with an alcohol ester of a higher fatty acid having a specified structure and an organopolysiloxane. SOLUTION: This composition is obtained by compounding 100 pts.wt. resin composition comprising (D) 20-40 pts.wt. graft copolymer prepared by carrying out the graft copolymerization of 5-80 pts.wt. rubber-like polymer having 0.1-2.0μm weight-average particle diameter with 95-20 pts.wt. monomer mixture comprising (A) an aromatic vinylic monomer, (B) a vinyl cyanide-based monomer and (C) other two or more copolymerizable vinylic monomers and (E) 80-60 pts.wt. vinylic copolymer, composed of two or more of the monomers (A), (B) and (C) and having 0.2-1.0dL/g reduced viscosity with (F) an esterified substance of a 16-34C higher alcohol with a 16-34C higher fatty acid and (G) 0.5-5.0 pts.wt. organopolysiloxane having 0.05wt.% cyclic oligomer component content.
