A scroll compressor comprises a stationary scroll(1) having an involute wrap, a rotatable scroll(2) having a symmetrical involute wrap to the stationary one, a main frame supporting the rotatable scroll, a stopper(3) for restricting the rotation of the rotary scroll while allowing its revolution, and a driving shaft rotated by a motor. For correcting the revolution radius of the rotatable scroll in the scroll compressor, a driving shaft pin(4a) is eccentrically formed at the end of the driving shaft(4), and a driving bush(7) having an eccentric shaft bore is movably mounted between the driving shaft pin(4a) and the boss of the rotatable scroll so as to allow the distance between the center line of the driving shaft and that of the driving shaft pin to be changed. The driving bush is further provided with a motion limit means(8) for adjusting the motion range.
