PROBLEM TO BE SOLVED: To provide a tool for preventing damage by bird which is hardly tilted even when it is attached to an electric wire with an axial direction projection on an outer surface of the electric wire.SOLUTION: An electric wire fixing part 2 of a tool for preventing damage by bird 1, comprises a first holding part 24 and a second holding part 30. A groove part 26 can fit an axial direction projection 310 that is the axial direction projection 310 provided onto an external surface of an electric wire 300, and is provided along an axial direction α of the electric wire 300 with looseness. The plurality of groove parts are provided to a contact surface of the first holding part 24 in the electric wire fixing part. Thus,a force for releasing from a position which is operated when the projection 310 is nipped is not worked to the axial direction projection 310 of the electric wire 300. Therefore, the tool for preventing damage by bird 1 is hardly inclined even attached to the electric wire 300 having the axial direction projection 310 on the external front surface of the electric wire 300.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】電力線の外部表面上に軸方向突起を有する電力線に取り付けても傾きにくい鳥害防止具を提供する。【解決手段】鳥害防止具1の電力線固定部2は、第1把持部24と、第2把持部30とを備えている。電力線300の外部表面上に設けられた軸方向突起310であって、電力線300の軸方向αに沿って設けられた軸方向突起310を、遊びをつけて嵌め合わせることが可能な溝部26が、第1把持部24の当接面に複数設けられている。このようにすると、電力線300の軸方向突起310には、突起310が挟まれた時に働く、その位置から脱しようとする力が働かない。したがって、この鳥害防止具1は、電力線300の外部表面上に軸方向突起310を有する電力線300に取り付けても傾きにくい。【選択図】 図1
