To provide a trap which is excellent in strength of a locking portion of a tip of a spring storage cylinder for locking a compression coil spring in a compressed state.SOLUTION: A coil spring 6 is inserted into a cylinder and a compression coil spring 5 is compressed and housed in a spring storage cylinder 6, a coiled wire is inserted into the cylinder and is urged from the tip of the compression coil spring , And the moving cylinder has a lock pin 30. When the compression coil spring is compressed, it is inserted into the spring accommodating cylinder, and the engagement It is possible to stop. Since the wall thickness of the locking portion at the tip of the spring storage tube can be increased, the strength is improved.(FIG.【課題】圧縮状態の圧縮コイルばねを係止するばね収納筒先端の係止部の強度に優れたくくり罠を提供する。【解決手段】くくりワイヤー2が筒内に挿通され、圧縮コイルばね5が圧縮されて収納されるばね収納筒6と、くくりワイヤーが筒内に挿通され、圧縮コイルばねの先端から付勢されることによりくくり輪4を縮径する移動筒7と、を備え、移動筒はロックピン30を有し、圧縮コイルばねが圧縮された状態でばね収納筒内に挿入して、ロック溝31により係止可能とする。ばね収納筒の先端の係止部の肉厚を大きくできるので強度が向上する。【選択図】図2
