PURPOSE: A driving scroll turning device for scroll compressor is provided to reduce power loss and prevent vibration and oil leakage by allowing the driving scroll to perform a perfect revolutionary motion. CONSTITUTION: A scroll compressor comprises a crank shaft(32) rotating by an electric motor(31); a driving scroll(33) performing swirling motion by the crank shaft; a fixed scroll(36) engaged with the driving scroll so as to compress and expand fluid; a bearing pin(35) fixed to the driving scroll; a bearing(38) formed integrally with the bearing pin; and a concentric hole(34) formed at the inner surface of a housing(41). The bearing formed integrally with the bearing pin which is fixed to the driving scroll moves contacting the concentric hole, upon rotation of the crank shaft, so as to permit the driving scroll to perform a perfect revolutionary motion.
