ABSTRACT:
An eccentric coupling device in a radial compliance scroll compressor including a crank pin eccentrically arranged at an upper end of a crankshaft included in the scroll compressor, and provided with a vertically-extending cut surface at one side thereof, a bush fitted around the crank pin, and provided with a crank pin hole and a stopper hole, a stopper fitted in the stopper hole, and an engagement jaw adapted to prevent a vertical movement of the stopper, thereby preventing a vertical movement of the bush, the engagement jaw being provided at an upper end of the crank pin. The bush is arranged such that an upper end thereof is flush with an upper end of the crank pin. The stopper hole overlaps with the crank pin hole so that the stopper selectively comes into contact with the cut surface in accordance with a rotation of the crank pin. The stopper has a length shorter than that of the stopper hole.
