PROBLEM TO BE SOLVED: To provide a binding trap allowing quicker binding of a trap loop without making the trap large-scale.SOLUTION: A binding trap includes: a base member 40 disposed on the other side of a binding wire 14, allowing a middle part of the binding wire 14 to pass, and formed such that a part 14c on the other end side of the binding wire 14 is held a moving pulley 30 on which the binding wire 14 is hung and wound between a part in which the binding wire 14 passes through the base member 40 and the part 14c on the other end side a compression coil spring 17 disposed between a fastening member 15 and the base member 40 in a state that the binding wire 14 is passed therethrough, and pressing the fastening member 15 so as to bind a trap loop 14a when elongating from a compression state and a torsion spring 50 urging the moving pulley 30 in such a direction as to move away from the base member 40 so that the moving pulley 30 is moved in a direction in which the trap loop 14a is bound.COPYRIGHT: (C)2014,JPO&INPIT【課題】仕掛けが大掛かりにならず、罠用ループをより素早くくくることができるくくり罠を提供することにある。【解決手段】くくり用ワイヤー14の他方の側に配され、くくり用ワイヤー14の中途部が通過できると共にくくり用ワイヤー14の他方端側の部位14cが保持されるように形成された基部材40と、くくり用ワイヤー14が、基部材40を通過する部位から他方端側の部位14cの間において掛け回される動滑車30と、締付部材15と基部材40との間で前記くくり用ワイヤー14が通されて配され、圧縮状態から伸びる際に罠用ループを14aくくるように締付部材15を押圧する押しコイルバネ17と、動滑車30を、罠用ループ14aがくくられる方向へ移動させるように、基部材40から離れる方向へ付勢するトーションバネ50とを具備する。【選択図】図20
