PROBLEM TO BE SOLVED: To provide an animal intrusion prevention device that can be made at low cost and prevents the intrusion of an animal efficiently.SOLUTION: An animal intrusion prevention device 1 is configured by comprising: mesh materials 30a, 30b configured by twisting multiple threads having flexibility multiple times and support materials 10 disposed in an installation surface, positioned between the installation surface and the mesh materials 30a, 30b, and supporting the mesh materials 30a, 30b being in an inclined state to the installation surface. The mesh materials 30a, 30b are disposed by separating one end of the mesh materials 30a, 30b from the installation surface while being bent in the axial direction of a twisted portion with multiple threads twisted. The meshes provided at the mesh materials 30a, 30b are formed so that some mesh size has the size of allowing entry of an animals leg. The height of the support material 10 is configured in the height of 2/3 or less of the height of the mesh material in an installed state.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】低コストに製作でき、かつ、効率的に動物の侵入を防止する動物侵入防止装置を提供する。【解決手段】動物侵入防止装置1は、可撓性を有する複数本の線条を複数回ねじり合わせて構成された網材30a,30bと、設置面に配置され、設置面と網材30a,30bとの間に位置し、設置面に対して傾斜した状態の網材30a,30bを支持する支持材10とを含み構成されている。網材30a,30bは、複数本の線条をねじり合わせたねじり部分の軸方向に撓ませた状態で、網材30a,30bの一方の端部を設置面と離間して配置され、網材30a,30bに設けられた網目は、一部の網目の大きさが動物の脚が入り込む大きさに形成され、支持材10の高さは、設置された状態における前記網材の高さの2/3以下の高さに構成されている。【選択図】図1
