PROBLEM TO BE SOLVED: To provide a fixture for forming a wire-threading hole, so designed that: for a threading hole formed by foldingly bending the end of each of wires, the hole can be fixed so as to maintain its function with keeping its configuration intact, and to provide a tying trap using the fixture.SOLUTION: The fixture is a cylindrical member 11 formed flatly in a nearly 8-shaped manner so as to enable wires 21 to be threaded in parallel to one another in order to make a threading hole 25 formed by fixing the end 21a of each of the wires 21 through bending the end 21a in a loop-shaped manner, and provided so as to be firmly fixed onto the wires 21 by being deformed under crimp contact and on the side of one opening end 11a of the cylindrical member 11, on one of the flanks 11c in the arrangement direction of the wires 21, a notch 12 for the terminal end 21b of each of the wires 21 where the end of each of the wires 21 is fitted so as to be fixed by being bent at an obtuse angle for effecting antislipping is formed, thus the cylindrical member 11 is provided so as to be firmly fixed onto the wires 21 by being deformed under crimp contact.COPYRIGHT: (C)2012,JPO&INPIT【課題】ワイヤーの端部を折り返すように曲げて形成される通し孔について、その通し孔の形態を保持してその機能を維持するように固定できるワイヤー通し孔形成用の固定具及びそれを用いたくくり罠を提供すること。【解決手段】ワイヤー21の端部21aをループ状に曲げて固定することで形成される通し孔25を設けるために、ワイヤー21が並列状態に挿通できるように断面が略8の字状の偏平に形成され、圧着変形されることでワイヤー21に固着されるように設けられた筒状部材11であって、その筒状部材11の一方の開口端部11a側でワイヤー21の並び方向の一方の側面部11cに、ワイヤーの末端部21bが抜け止めのために鈍角に曲げられて固定されるように嵌め込まれるワイヤー末端部用の切り欠き部12が形成され、圧着変形されることで固着されるように設けられている。【選択図】図1
