Claim:
An eccentric coupling device in a radial compliance scroll compressor, the eccentric coupling device comprising: a crank pin eccentrically arranged at an upper end of a crankshaft included in the scroll compressor, a vertically-extending flat surface provided at one side of the crank pin; a bush provided with a crank pin hole configured to receive the crank pin, and a stopper hole provided in the bush at one side of the crank pin hole such that the stopper hole overlaps with the crank pin hole; a stopper fitted in the stopper hate such that the stopper radially protrudes into the crank pin hole toward the flat surface to selectively come into contact with the flat surface in accordance with a rotation of the bush; a vertical movement preventer configured to prevent a vertical movement of the stopper, thereby preventing a vertical movement of the bush, the vertical movement preventer being provided at an upper end of the crank pin; wherein the vertical movement preventer comprises a stopper insertion groove through which the stopper is passed at an upper end of the crank pin; and an engagement jaw horizontally protruding from an upper end of the flat surface such that the engagement jaw is engagable with a part of the stopper fitted in the stopper hole.
