PROBLEM TO BE SOLVED: To provide a bird damage prevention tool which is easily attached to a long cable with a simple structure.SOLUTION: A bird damage prevention tool of the invention includes: a body part capable of storing an aerial cable therein and having a cylindrical shape a needle-like part extending from the body part in a radial direction and a notch part which allows the interior of the cylindrical shape to communicate with the exterior on a cross section perpendicular to an axial direction of the body part. When the aerial cable is inserted into the body part, the aerial cable passes through the notch part to be stored in the body part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】単純な構成で、長さの長いケーブルに対して、簡単に取り付けることが可能な鳥害防止具を提供する。【解決手段】本発明の鳥害防止具は、架空ケーブルを内部に収容可能な円筒形状の本体部と、本体部から半径方向に伸びる針状部と、本体部の軸方向に対して垂直な断面において、円筒形状の内部から外部にかけて連通する切込部とを有し、架空ケーブルを本体部に挿入する場合に、切込部を架空ケーブルが通過して本体部の内部に収容される。【選択図】図1
