Abstract
A compound bow has an improved vibration damping function. The compound bow includes a bow main body including a handle and a pair of limbs; upper and lower pulley assemblies each including a pulley and a cam; a bowstring; 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; a bowstring support bar whose one end is coupled to the handle and whose other end is coupled to a cushioning member that contacts the bowstring; and a first cam cable anti-vibration bar including a coupling bar coupled to the handle, and an anti-vibration member that is coupled to the rear end of the coupling bar and whose rear surface contacts one of the first and second cam cables when the bowstring is released to thus return to an original position.
