PROBLEM TO BE SOLVED: To provide an animal intrusion prevention fence capable of coping with hole digging by animals.SOLUTION: In the animal intrusion prevention fence for which a fence body comprising a wire net using crimped wires is fixed between a plurality of columns, the wire net is composed by arranging vertical lines 2 and horizontal lines 3 with wavy irregular parts vertically and horizontally in parallel. The vertical line 2 is inserted to the irregular part of adjacent two or more horizontal lines 3 shifted by a half pitch and engaged at the upper and lower parts. The two or more horizontal lines 3 are turned to one set, the adjacent sets of the horizontal lines 3 are separated by 3 pitches or longer from each other, and the wire net is deformable into a parallelogram. One set of two or more side vertical lines 2 and one set of horizontal lines 3 are entangled to form a four-side frame 6, and the four-side frame 6 is formed at both side parts of the fence body. The lower end parts of the respective vertical lines are inserted to the irregular part of at least three adjacent horizontal lines 3c at the lower end parts at an interval with the shift of 1.5 or 2.5 pitches and engaged, and the at least three horizontal lines 3c at the lower end parts are buried underground together with the lower end parts of the vertical lines 2.COPYRIGHT: (C)2012,JPO&INPIT【課題】動物の穴掘りに対処可能な動物侵入防止フェンスを提供すること。【解決手段】クリンプされた線材を使用した金網からなるフェンス本体が複数の支柱間に固定された動物侵入防止フェンスにおいて、金網は波形凹凸部分が形成された縦線2と横線3が各々縦横平行に配置されてなり、縦線2はその上部及び下部において、隣接する半ピッチずれた2本線以上の横線3の凹凸部分に通されて係合され、この2本線以上の横線3を1組として、隣接する横線3の組が互いに3ピッチ以上離れて、金網が平行四辺形に変形可能にされ、2本線以上の1組の側部縦線2と1組の横線3が絡み合って四方枠6が形成され、四方枠6がフェンス本体の両側部に形成され、各縦線の下端部には、隣接する1.5又は2.5ピッチずれて間隔をおいた少なくとも3本の下端部の横線3cの凹凸部分に通されて係合され、少なくとも3本の下端部の横線3cを縦線2の下端部と共に地中に埋め込む。【選択図】図1
