The present invention locks the engagement and disengagement of the trigger lever in the locking rod portion and can hold the confinement door body in the opening state, a small animal capture that can be closed operating confinement door body by trampling of small animals It provides the vessel. A is cage-like body 1 of the front of the entrance section 2 confinement door 3 capable of opening and closing the provided, tread member 4 is disposed tiltably in cage-like body 1. As interlocking mechanism 5 for closing the confinement door 3 by tilting of the tread member 4, a trigger lever 5b on the upper surface of the cage-like body 1 is disposed to move forwards and backwards, the trigger piece 5c is disposed on the tread plate member 4, The trigger lever 5b the trigger piece 5c is passed loosely, the trigger rod 5b rear portion is disposed to abut against possible contact portion 5d to the trigger piece 5c of the locking rod portion 6 is disposed in the confinement door 3 , it would have arranged detachably a disengaged portion 7 to the front of the trigger rod 5b the locking rod portion 6. .BACKGROUND【課題】トリガー杆の係脱部を係止杆部に係止して閉込扉体を開口状態に保持することができ、小動物の踏圧により閉込扉体を閉口動作させることができる小動物捕獲器を提供する。【解決手段】かご状本体1の前面の進入口部2を開閉可能な閉込扉体3が設けられ、かご状本体1内に踏板部材4が傾動自在に配設される。踏板部材4の傾動により閉込扉体3を閉口させる連動機構5として、かご状本体1の上面にトリガー杆5bを進退移動自在に配設し、踏板部材4にトリガー片5cを配設し、トリガー片5cにトリガー杆5bを遊挿通し、トリガー杆5bの後部にトリガー片5cに当接可能な当接部5dを配設し、閉込扉体3に係止杆部6を配設し、トリガー杆5bの前部に係止杆部6に係脱可能な係脱部7を配設してなる。【選択図】図1
