PROBLEM TO BE SOLVED: To provide a bird injury prevention tool which is easily fitted to an electric line EL while being coupled even if it is an indirect hot line.SOLUTION: The bird injury prevention tool comprises a main body part, a first fitting part, a second fitting part and a bird injury repellent part. A first cylindrical part includes a first crack, and a second cylindrical part includes a second crack. The first fitting part includes a pair of first legs and a first guide part that is provided at a free end side of the first legs for guiding an installation body between the first legs. The second fitting part includes a pair of second legs and a second guide part that is provided at a free end side of the second legs for guiding a first cylindrical body between the second legs. The first cylindrical part includes arcuate projections in a circumferential direction of the first cylindrical part, the projections being provided on an outer peripheral surface of the first cylindrical part outside of the first legs in a view from the first crack. The second cylindrical part includes a long hole that is continued from the second cylindrical part to the second legs along a cross section that is vertical to a central axis of the second cylindrical part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】連結しながらの電線ELへの取り付けが間接活線でも容易な鳥害防止具を提供することを目的とする。【解決手段】本体部と、第1取付部と、第2取付部と、鳥害忌避部と、を備え、第1筒状部は、第1割目を有し、第2筒状部は、第2割目を有し、第1取付部は、一対の第1脚部と、第1脚部の遊端側に設けられ、第1脚部の間に架設体を案内する第1案内部と、を備え、第2取付部は、一対の第2脚部と、第2脚部の遊端側に設けられ、第2脚部の間に第1筒状体を案内する第2案内部とを備え、第1筒状部は、第1筒状部の周方向に沿った円弧形状の突起であって、第1割目から見て第1脚部よりも外側の当該第1筒状部の外周面上にそれぞれ設けられた突起を備え、第2筒状部は、この第2筒状部の中心軸に垂直な断面に沿って、当該第2筒状部から第2脚部まで連続する長孔を有する。【選択図】図1
