The present invention enclosed worry about the set of the coil spring member for bundling and reducing the diameter of the annulus of the trap is a coil spring is popping in vibration during transportation along with the easily performed at home is eliminated, extremely is enclosed set of trap in the safe and local The result shall be performed in a simple and short, further Tsutsumikyo a spring-type clamping device pressing reliably capture can enclose a trap without cutting the ankle beasts. Against A traditional enclosed trap, coil spring member 3, a coil spring 31 for reducing the diameter of the ring portion 1a enclose, the pipe 32 that houses it, the cap pipe 33 to be capped in the pipe 32 , a guide rod 34 for accommodating the coil spring 31 to the pipe 32 provided with the side the cap pipe 33, and a. Furthermore, at least equipped with a spring 5 for vibration neck between the distal end portion of the clamping member 2 and the coil spring member 3 and the engaging groove 32a is provided at one end of the pipe 32, and engaging the inside of the cap pipe 33 It and structure provided with a convex portion 33a for engaging in groove 32a. .BACKGROUND【課題】括り罠の括り輪部を縮径するためのコイルバネ部材のセットが自宅で容易に行えると共に運搬中の振動でコイルバネが飛び出る心配もなくなり、安全で且つ現地での括り罠のセットが極めて簡単で短時間に行えるものとなり、更に獣類の足首を切断することなく確実に捕獲できる括り罠用押しバネ式締付装置を堤供する。【解決手段】従来の括り罠に対して、コイルバネ部材3が、括り輪部1aを縮径するためのコイルバネ31と、それを収納するパイプ32と、該パイプ32に冠着するキャップパイプ33と、該キャップパイプ33側に設けると共にコイルバネ31をパイプ32に収納するための案内棒34と、から成る。さらに、締付体2とコイルバネ部材3の先端部との間に首振用のバネ5を少なくとも装着し、且つ、パイプ32の一端部に係止溝32aを設け、キャップパイプ33の内部に係止溝32aに係止する凸部33aを設けた構造とする。【選択図】図1
