< Topic >The simple structure which the operational part the possession is not done, dividing inside the channel of the fence lower part appropriately, it offers the blockade device for the animal repellency which from field side outside the fence of the animal in the channel can prevent the movement to road side securely.SolutionsPassing through the blockade body 20 which has the many open part to the rectangular opening of the foundation 10 which is locked to fence 50 lower part, from above, when distribution facilities it does, blockade body 20 the extent which from road side faces on field side outside the fence it is located to the channel 61 specified inclined when it goes down, receiving power from field side outside the fence, conduct of the animal and the like which from the fact that you can obtain a state where blockade body 20 does not move and/or does not become deformed, maintains the blockade of the channel 61 by blockade body 20 with the lower part of fence 50, inside channel 61 from field side outside the fence it tries to advance to road sideVis-a-vis, the blockade body 20 which blocks the animal and the like being pushed in the animal, and the like without moving, it maintains the position inside the channel, it comes to the point of with being able to obstruct the advance of the animal and the like to ahead from this blockade body 20 position, it can prevent the invasion to the road of the animal and the like by way of the channel 61 securely.< Choice figure >Drawing 2【課題】可動部分を有しない簡略な構造ながら、フェンス下方の溝内を適切に仕切って、確実に溝での獣のフェンス外領域側から道路側への移動を防止できる防獣用閉塞装置を提供する。【解決手段】フェンス50下部に固定される基礎部10の矩形開口部に、多数の開放部分のある閉塞体20を上から通して配設し、閉塞体20を道路側からフェンス外領域側に向かうほど下がる所定の傾斜状態で溝61に位置させると、フェンス外領域側から力を受けても閉塞体20が動いたり変形したりせず、フェンス50の下方で閉塞体20による溝61の閉塞を維持する状態が得られることから、溝61内でフェンス外領域側から道路側へ進行しようとする獣等の行動に対し、獣等を遮る閉塞体20が獣等に押されても動かずに溝内位置を維持し、この閉塞体20位置より先への獣等の進行を阻止できることとなり、溝61を経由した獣等の道路への侵入を確実に防止できる。【選択図】図2
