Abstract
Provided is a compound bow comprising: a bow main body; upper and lower pulley assemblies; a bowstring; and first and second cam cables, wherein at least one of the first and second cam cables is coupled to the fixing projection that moves along as a cam module moves, is wound on a cam cable winding portion via a compensation projection, and then extends toward the other side pulley assembly, and a front portion of the cam module is in contact with the one cam cable and thus the one cam cable is bent when the cam module is moved, to thus release the one cam cable from the cam cable winding portion via the compensating projection from the fixing projection that the one cam cable is coupled, to thereby maintain constant tension of the cam cable and keep the power of the bow.
