1. An eccentric bush structure in a radial compliance scroll compressor, the eccentric bush structure comprising: an eccentric bush fitted around a crank pin eccentrically arranged at an upper end of a crankshaft, the crank pin having a flat peripheral surface; a crank pin hole provided in the eccentric bush, and configured to receive the crank pin; a stopper hole provided in the eccentric bush at one side of the crank pin hole such that the stopper hole overlaps with the crank pin hole, the stopper hole receiving a stopper such that the stopper radially protrudes into the crank pin hole toward the flat surface of the crank pin to selectively come into contact with the flat surface in accordance with a rotation of the eccentric bush; and a weight configured to increase a weight of the eccentric bush, and increase an eccentric amount of the eccentric bush, wherein the weight is arranged on an outer peripheral surface of the eccentric bush at a position radially spaced from a center of the crank pin hole by a maximum distance.
