PURPOSE: A radial adaptation structure for scroll compressor is provided to reduce a frictional loss occurring at the bearing surface and manufacturing cost for rotating shaft by reducing the diameter of the rotating shaft. CONSTITUTION: An eccentric bush(200) is interposed between an outer circumference of a driving pin(110) of a rotating shaft(100) and an inner circumference of a boss of a scroll(6), and coupled to be rotatable to the rotating shaft. A stopper pin(300) is interposed to be movable between the front end surface of the rotating shaft and the opposed side surface of the eccentric bush, so as to restrict the radial movement of the eccentric bush. The driving pin of the rotating shaft has a stopper surface(130) which tightly contacts the outer surface of the stopper pin so as to restrict the eccentric bush from moving in a radial direction within a predetermined range. Since the stopper pin is arranged to contact the driving pin of the rotating shaft, the rotating shaft has a reduced diameter. Thus, the bearing surface between the rotating shaft and a main frame(2) is reduced, to thereby reduce a frictional loss occurring at the bearing surface.
