An eccentric coupling device in a radial compliance scroll compressor including: a crank pin eccentrically arranged provided at an upper end of a crankshaft included in the scroll compressor, and provided with a vertically-extending cut surface at one side thereof; an eccentric bush provided with a crank pin hole adapted to receive the crank pin, and a stopper hole provided at the eccentric 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 hole such that the stopper is radially protruded into the crank pin hole toward the cut surface to selectively come into contact with the cut surface in accordance with a rotation of the bush; and a spring wire adapted to elastically support the eccentric bush, while connecting the stopper and the crank pin, thereby preventing an elevation of the eccentric bush. The spring wire also serves to suppress a backward rotation of the eccentric bush, while elastically recovering the eccentric bush when the backward rotation of the eccentric bush has occurred.
