PROBLEM TO BE SOLVED: To provide a bird damage prevention device which can easily pass between a set of edge lines. SOLUTION: A bird damage prevention tool 10 includes a prevention tool main body 1 and a strip-shaped bar member 2. The preventive tool main body 1 includes a substrate 11 and a plurality of needle bodies 12. The plurality of needle bodies 12 stand in a divergent shape along the longitudinal direction of the substrate 11. The bar member 2 opens a plurality of regulation holes 2h into which the needle body 12 is inserted in a row. Further, the bar member 2 is movably connected to the plurality of needle bodies 12 in a state of crossing the plurality of needle bodies 12. In a state where the bar member 2 is moved toward the base end side of the needle body 12, the bird damage prevention tool 10 can open a plurality of needle bodies 12. In a state where the bar member 2 is moved toward the tip end side of the needle body 12, the bird damage prevention tool 10 can close a plurality of needle bodies 12. By closing the angle of the plurality of needle bodies 12, the bird damage prevention device 10 can be easily passed between the set of edge lines We and We. [Selection diagram] Fig. 1【課題】一組の縁線の間を容易に通過できる鳥害防止具を提供する。【解決手段】鳥害防止具１０は、防止具本体１と帯板状のバー部材２を備える。防止具本体１は、基板１１と複数の針体１２を備える。複数の針体１２は、基板１１からその長手方向に沿って末広がり状に林立している。バー部材２は、針体１２が挿入される複数の規制孔２ｈを一列に開口している。又、バー部材２は、複数の針体１２を横断した状態で、複数の針体１２と移動自在に連結している。バー部材２を針体１２の基端部側に向かって移動した状態では、鳥害防止具１０は、複数の針体１２を開角できる。バー部材２を針体１２の先端部側に向かって移動した状態では、鳥害防止具１０は、複数の針体１２を閉角できる。複数の針体１２を閉角することで、一組の縁線Ｗｅ・Ｗｅの間に鳥害防止具１０を容易に通過できる。【選択図】図１
