Problem to be solved: to provide an object capturing device constructed so that the diameter of the capture wire can be reduced in the shortest distance and the shortest time, despite the simple structure.A left and right wire holding body having a semicircular arcuate shape which supports both ends on the side wall of the cylinder base and the left and right sides of each side of the cylindrical foundation, respectivelyThe loop portion of the capture wire which surrounds the circular arc outer surface of the left and right wire retaining body in the collapsed state of the left and right wire retaining body andThis structure is composed of a wire shrinking mechanism which pulls the loop portion of the wire surrounding the left and right wire retaining bodies to reduce the diameter of the loop.Diagram【課題】簡易な構造にもかかわらず最短距離と最短時間で、捕獲ワイヤの縮径作動が行えるように構成した害獣捕獲具を提供せんとするものである。【解決手段】周縁に側壁を立ち上げた筒基盤と筒基盤の側壁に両端部をそれぞれ枢支し左右それぞれを起立付勢した半円弧状の左右ワイヤ保持体と、左右ワイヤ保持体の倒伏状態で左右ワイヤ保持体の半円弧外周面を囲繞した捕獲ワイヤのループ部と、左右ワイヤ保持体を囲繞したワイヤのループ部基部を引張ってループを縮径付勢するワイヤ縮径付勢機構とにより構成した。【選択図】図1
