PROBLEM TO BE SOLVED: To provide a wild animal invasion prevention device capable of reliably preventing a wild animal from invading.SOLUTION: A wild animal invasion prevention device includes: a panel 1 made by arranging main members 3 within a rectangular frame 2 side by side at fixed intervals in a lateral (right/left in a drawing) direction shown by an arrow so as to face an invasion direction of an animal as a travel direction of a passage, and fixing and integrating auxiliary members 4 formed zigzag in bent crests and valleys to the main members 3 and an opaque sheet 18 covering the panel 1, having a periphery fastened on the frame 2 of the panel 1, and made of rubber or resin. The sheet 18 has cuts 19 in a cross shape. The sheet 18 covers the panel 1 so that each of the cuts 19 is positioned in a center of an opening 5 of the panel 1.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2017,JPO&INPIT【課題】野生動物の侵入をより確実に防止することができる野生動物侵入防止装置を提供する。【解決手段】矩形の枠2内に主部材3を矢印で示す、通路の進行方向である動物の侵入方向に向けて横(図の左右)方向に一定間隔で並設すると共に、補助部材4をジグザグに形成して屈折した山及び谷で主部材3に固着し、一体化したパネル1と、該パネル1に被せられ、周縁がパネル1の枠2に止着されるゴム又は樹脂製の不透明なシート18よりなり、該シート18には十文字の切れ目19が入れられ、各切れ目19がパネル1の開口5の中央部に位置するようにシート18がパネル1に被せられる。【選択図】図8
