< Topic >It is superior in the effect which repels the birds and beasts, furthermore, it offers the birds and beasts damage eliminator which is superior in endurance.SolutionsVis-a-vis support component such as standards component, it provides the adapter unit 3 of hanging member T in the upper part of the infrastructure component, 2 which possesses the optical reflecting interface which in the inside and outside is reflected in Takata direction by the lower part of the said infrastructure component 2 from width of the said infrastructure component 1 at the same time directing to the lower part widely, it droops, making condition extend, it provides the wind receiving component 4,5 of left and right pair, in left and right direction and forms birds and beasts damage eliminator 1. It hangs the said birds and beasts damage eliminator 1 and through the component, by the fact that fluctuation unrestrictedly it hangs, smoothly fluctuation it is possible even at the time of the breeze vis-a-vis the support component to turn.< Choice figure >Drawing 2【課題】鳥獣を追い払う効果に優れ、しかも、耐久性に優れる鳥獣害防止器を提供する。【解決手段】支柱部材等の支持部材に対し、表裏に多方向に反射する光反射面を有する基盤部材2の上方に吊下部材Tの取付部3を設け、該基盤部材2の下方に左右一対の風受け部材4,5を、該基盤部材1の幅より左右方向に幅広にして、且つ下方に向けて垂れ状に延長させて設けて鳥獣害防止器1を構成する。該鳥獣害防止器1を吊り下げ部材を介して支持部材に対して揺動自在に吊下げることで、微風の時でも円滑に揺動と回転させることができる。【選択図】図2
