    摘要: Provided is a polycarbonate-based resin composition for sliding use including 0.01 to 1 part by mass of an antioxidant with respect to 100 parts by mass of a polycarbonate-polyorganosiloxane copolymer which has structural units represented by a general formula (A) and structural units represented by a general formula (B), which contains a polyorganosiloxane block moiety containing the structural units represented by the general formula (B) at a content of 1 to 30 mass %, and which has an average repetition number of the structural units represented by the general formula (B) of 110 to 1000. The polycarbonate-based resin composition for sliding use has a specific structure having improved wear resistance, in particular, improved sliding property. Also provided is a molded article using the resin composition, and excellent in wear resistance and sliding property.
