PROBLEM TO BE SOLVED: To solve problems that strength and weakness of flipping force for flipping a terminal tackle string can not be adjusted, when the pressure applied to a stopper is brought to be stronger to prevent misoperations, the terminal tackle string is difficult to be flipped and the position for putting the terminal tackle can not be set at an arbitrary desired position.SOLUTION: The flipping degree of the terminal tackle string is brought to be adjustable by providing a mobile weight to a lever rod for releasing the stopper of a crank in a lock-releasing system for dropping the door of an injurious animal-trapping cage, the position of the terminal tackle string is brought to be settable at the arbitrary desired position in the fore or back direction from the central part of the cage by rotatively moving in the horizontal direction within an almost semicircle by bringing one end of the lever rod as an axis, and the spring force for pulling the crank applied to the stopper is brought to be stronger in order to prevent the misoperations, even though the lock releasing is difficult, thus lock releasing can be brought to be sure by pulling down the falling substance with weak force by a slight touch of the animal to the terminal tackle string to collide with the lever rod which is moved downward by the drop impact.COPYRIGHT: (C)2012,JPO&INPIT【課題】仕掛け糸を弾く力の強弱を調整出来ないことと誤作動を防ぐ為にストッパ-に掛かる圧力を強くすると仕掛け糸が弾き難いことや、仕掛け位置が希望する任意位置に設定出来ないとゆう点である。【解決手段】害獣捕獲オリの扉を落下さす開錠システムの中でクランクのストッパ-を外すテコ竿に移動錘を設けて仕掛け糸の弾き具合を調整可能にして、テコ竿の一端を軸として概ね半円内で水平方向に回転移動さして仕掛け糸位置をオリの中心部より手前又は奥行き方向に希望する任意位置に設定可能にし、誤作動を防ぐためにストッパ-にかかるクランクを引き付けるスプリングの力を強くして開錠し難くても、落下物を引き糸につながる仕掛け糸を獣が軽く触れる弱い力で引き落としてテコ竿に衝突さし落下衝撃でテコ竿を下方向に移動さし開錠を確実にした。【選択図】図1
