Provided is a compound bow including: first and second cam cables between upper and lower pulley assemblies, wherein the lower cable of the first cam cable comprises: a one-side cable portion and the other-side cable portion on both sides of the pulley, in which either end of the lower cable is coupled to a fixing projection formed at either side of the pulley, and the one-side cable portion and the other-side cable portion of the lower cable are supported by a spacing member so as to maintain a constant interval, to thus make the one-side cable portion and the other-side cable portion of the lower cable wound on the respective cams formed at both sides of the pulley, while maintaining the one-side cable portion and the other-side cable portion of the lower cable to have the constant interval by the spacing member, as a bowstring is pulled. |

1. A compound bow comprising:
a bow main body including a handle at a central portion of which a grip portion is formed and a pair of limbs that are respectively coupled to both ends of the handle; upper and lower pulley assemblies each including a pulley that is rotatably coupled to a rotating shaft formed on the rear end of each limb, and a cam that is coupled to the pulley and is rotated with the pulley; a bowstring whose either end is wound on and coupled to the pulley of each of the upper and lower pulley assemblies; and first and second cam cables that are wound around the cam of each of the upper and lower pulley assemblies as the bowstring is pulled, in which one end of each of the first and second cam cables is coupled to one of the upper and lower pulley assemblies, and the other end thereof is coupled to the other of the upper and lower pulley assemblies or the rotating shaft of the other of the upper and lower pulley assemblies, wherein the respective cams are provided on one side and the other side of the pulley in the lower pulley assembly, the first cam cable comprises: a central cable; an upper cable that is connected to the upper side of the central cable; and a lower cable that is connected to the lower side of the central cable, the upper cable comprises: a one-side cable portion and the other-side cable portion that are positioned on both sides of the pulley of the upper pulley assembly, in which either end of the upper cable is coupled to the rotating shaft to which the upper pulley assembly is coupled at either side of the pulley of the upper pulley assembly, the lower cable comprises: a one-side cable portion and the other-side cable portion that are positioned on both sides of the pulley of the lower pulley assembly, in which either end of the lower cable is coupled to a fixing projection that is formed at either side of the pulley of the lower pulley assembly, and the one-side cable portion and the other-side cable portion of the lower cable are supported by a spacing member so as to maintain a constant interval, to thus make the one-side cable portion and the other-side cable portion of the lower cable wound on the respective cams formed at both sides of the pulley of the lower pulley assembly, while maintaining the one-side cable portion and the other-side cable portion of the lower cable to have the constant interval by the spacing member, as the bowstring is pulled, to thereby minimize twisting of the bow limbs and improve accuracy of an arrow. |
