Abstract: A bow including: a frame having a predetermined length; a first pulley and a second pulley arranged on a first position and second position of the frame respectively; a first small diameter cam and a first large diameter cam rotated interlocked with the first pulley; a second small diameter cam and a second large diameter cam rotated interlocked with the second pulley; a string fixed to the first pulley and the second pulley, the first pulley and the second pulley being rotated when the string is pulled; a first cable and a second cable arranged in a linear shape between the first (second) small diameter cam and the second (first) large diameter cam, the first cable and the second cable being elastically deformed by being wound around the second large diameter cam or the first large diameter cam when the string is pulled.

Abstract: A cable tensed between a pair of large and small diameter cams of a bow and elastically deformed to generate an elastic force for rotating the pair of large and small diameter cams and a pair of string cams rotated integrally with the pair of large and small diameter cams in a reverse direction when the string is drawn to rotate the pair of large and small diameter cams are rotated. The cable has: a first high-elasticity raw thread wound around one of the pair of large and small diameter cams; a second high-elasticity raw thread wound around the other of the pair of large and small diameter cams; and a low-elasticity raw thread which connects the first high-elasticity raw thread with the second high-elasticity raw thread, the low-elasticity raw thread being elastically deformed more easily than the first high-elasticity raw thread and the second high-elasticity raw thread.

Abstract: A bow capable of replacing the cable more easily is provided. A bow, includes: a bow body; a plurality of string cams around which each of both ends of a string for nocking an arrow is wound, the string cams being rotated when the string is drawn; a plurality of cable cams around which each of both ends of an elastically deformable cables is wound, each of the cable cams being rotated interlockingly with each of the string cams to elastically deform the cables; and a plurality of holders, each of the holders having a base portion pivotably held on each of both ends of the bow body and an end portion for rotatably holding each of the cable cams.

Abstract: A bow includes: a bow body; a first string cam provided on one end of the bow body to be rotatable, one end of a string being fixed to the first string cam; a first small diameter cam rotated with the first string cam, one end of a cable being wound on the first small diameter cam; a first large diameter cam rotated with the first string cam, one end of a cable being wound on the first large diameter cam; a second string cam provided on the other end of the bow body to be rotatable, the other end of the string being fixed to the second string cam; a second small diameter cam rotated with the second string cam, the other end of the cable being wound on the second small diameter cam; and a second large diameter cam rotated with the second string cam, the other end of the cable being wound on the second large diameter cam.
