To provide a branch base portion of a balance lever for preventing entanglement at the time of inputting a gimmick, by directly attaching the branch base portion to a portion protruding to a part of a float or a bamboo shoot, and at the time of flight and settling, Keep it in a protruding state, provide a balancing mechanism that can prevent entanglement with a very simple structure.SOLUTION: A parallel portion 6 of a wire rod is provided at a base portion of a forehole 4 projecting to a part of a float 9 or a part of a bamboo shoot, or a flat portion is provided at an end of a roof rubber, and a long hole of a branch base portion 5 of a balance lever 13 Are engaged with each other without rotating and the elongated hole is given a certain angle with respect to the balance bifurcate so that the balance lever 13 is kept protruding at a right angle at the time of flight 9 and comet flies and during sedimentation, To prevent entanglement.(FIG.【課題】仕掛けを投入する際の絡みを防止する為の天秤枝の枝基部を、浮きやコマセカゴの一部分に突出した部分に直接着合して設け、飛行時及び沈降時に、天秤枝が直角に突出した状態に保もたれ、極めて簡単な構造で絡みを防止できる天秤仕掛けを提供する。【解決手段】浮き9やコマセカゴの一部に突出した先穴4の基部に、線材の平行部6を設け、又はウキゴム端に扁平部を設け、これに天秤枝13の枝基部5の長穴が回転することなく着合して、長穴を天秤枝に対し一定の角度を持たせる事により、浮き9やコマセカゴの飛行時及び沈降時に、天秤枝13を直角に突出した状態に保ち、仕掛けの絡みを防止する。【選択図】図1
