PROBLEM TO BE SOLVED: To provide a beast invasion protective device and its usage, the device that reduces labor and cost burdened for installation, removal, storage or management, etc., is light weight and can easily be carried to a mountainous district, facilitates assembling, and is compatible with the beasts with a habit of digging up.SOLUTION: A beast invasion protective device concerning the invention is installed in an edge of the beast invasion protection area and/or in an outer edge in order to prevent beasts from invading a beast invasion protection area. The beast invasion protective device is the device using a meshed panel constituted of multiple ribs having surfaces and backsides, and extending in the longitudinal direction spaced apart in the lateral direction, and a net provided with multiple protrusions on the surface and the backside and stretched between the multiple ribs. The protrusions being laid in an outer edge of the beast invasion protection area and exposed to the surface or the backside perform cutting of the bodies of beasts being brought into contact with this, and thereby it can prevent the invasion to the beast invasion protection area.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】設置・撤去・保管や管理等に負担する労力・コストを軽減し、軽量で容易に山地に運搬可能で、組み立て容易であり、掘り進む習性のある獣類にも対応できる獣類侵入防護装置及びその使用方法を提供する。【解決手段】発明に係る獣類侵入防護装置は、獣類侵入防護地域に獣類が侵入するのを防止するために獣類侵入防護地域の縁部及び/又はその外縁部に設置する獣類侵入防護装置において、表面と裏面を有し、短手方向に間隔を空けて長手方向に延びる複数のリブと、該表面及び該裏面に複数の突起部を設けて、該複数のリブ間に張設された網と、から構成されたメッシュ状パネルを用いた装置であって、前記獣類侵入防護地域の外縁部に敷設し、前記表面又は前記裏面に露出した前記突起部が、これに接触した獣類の身体を切傷することにより、その獣類侵入防護地域への侵入を阻止し得る。【選択図】図1
