PROBLEM TO BE SOLVED: To provide a bird prevention device that can be installed with or without a slope of the upper surface of a roof.SOLUTION: A bird prevention device has multiple bird prevention net holders 2 installed at predetermined intervals L along an end edge frame S2 of a solar panel S. The holders 2 each include an inverted L-shaped upper bracket 5 having an upper horizontal wall and a hanging wall, and the L-shaped lower bracket having a lower horizontal wall and a vertical upright wall. Bolt rods 9 are projected from the vertical upright wall of the lower bracket to the horizontal direction outward, the hanging wall has long holes 10 where the bolt rods are inserted therein, and an upper bracket 5 is vertically slidable to the lower bracket. Nuts are threadedly engaged to the bolt rods 9, a bird prevention net 1 is clamped by the nuts and the hanging wall, furthermore, the bird prevention net 1 is made to have a hanging shape and comes in abutment with an upper surface Y1 of a roof Y, and thereby a lower end 1a is curved to the outside.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】屋根の上面の傾斜の有無にかかわらず設置することができる防鳥装置を提供する。【解決手段】ソーラーパネルＳの端縁フレームＳ2 に沿って所定の間隔Ｌをもって複数設置される防鳥ネット保持具２を有する。保持具２は、上水平壁部と垂下壁部を有する倒立Ｌ字型上金具５と、下水平壁部と垂直起立壁部を有するＬ字型下金具とを備える。下金具の垂直起立壁部から水平方向外方へボルト杆９を突設し、垂下壁部が、ボルト杆が差込まれる長孔10を有し、上金具５が下金具に対して上下スライド自在である。ボルト杆９にナットを螺合し、ナットと垂下壁部によって、防鳥ネット１を挟持し、しかも、防鳥ネット１を垂下状として屋根Ｙの上面Ｙ1 に当接して下端１ａが外側へ弯曲するように構成する。【選択図】図１
