PROBLEM TO BE SOLVED: To make it possible to freely set the number of stages and the height of electric fence wire of a wildlife invasion prevention fence, and easily change the number of stages and the height of the electric fence wire even after a long time since the installation of the wildlife invasion prevention fence.SOLUTION: When assembling the wildlife invasion prevention fence, a support pole is inserted into a spiral part of a support pole fixing part 102, and the electric fence metal fitting 101 is installed on the support pole. As a hook part 106 at a tip of a state setting part 105 is hooked to a wire member for forming an arm part 104, the support pole fixing part 102 makes a fixed state as the spiral part is tightened. In the fixed state, the electric fence metal fitting 101 is fixed to the support pole, and it is immovable. As the hook part 106 at the tip of the state setting part 105 is removed from the wire member for forming the arm part 104, the spiral part of the support pole fixing part 102 is loosened, and the support pole fixing part 102 makes a loose fit state. In the loose fit state, the electric fence metal fitting 101 is movable along the support pole. An electric fence wire grasping part 103 is formed of a wire member further extended from the arm part 104 to grasp the electric fence wire.COPYRIGHT: (C)2012,JPO&INPIT【課題】鳥獣侵入防止柵の電牧線の段数と高さを任意に設定可能とし、鳥獣侵入防止柵を設置してから長い時間が経過しても電牧線の段数と高さを容易に変更可能にする。【解決手段】鳥獣侵入防止柵を組み立てるとき、支柱固着部102の螺旋状の部分に支柱を通して、電牧金具101を支柱に取り付ける。アーム部104を形成する線材に状態決定部105の先端の鉤状の部分106を掛けると、支柱固着部102は螺旋状の部分が締まって固着状態となる。固着状態では、電牧金具101は、支柱に固定され、動かすことはできない。一方、アーム部104を形成する線材から状態決定部105の先端の鉤状の部分106を外すと、支柱固着部102の螺旋状の部分が弛み、支柱固着部102は遊嵌状態となる。遊嵌状態では、電牧金具101を支柱に沿って動かすことができる。電牧線把持部103は、アーム部104から更に伸びた線材で形成され、電牧線を把持する。【選択図】図1
