PROBLEM TO BE SOLVED: To provide a bird damage-prevention tool capable of adjusting a position between an electric wire and a wire corresponding to the length of a bird.SOLUTION: An electric wire fitting part 1 includes: an electric wire receiving part 4 for holding one end part of an electric wire D an electric wire presser part 3 journaled at an upper part of the electric wire receiving part 4 in a horizontal-axis rotatable manner, for supporting the other end part of the electric wire D and a fastening part 5 for drawing the electric wire receiving part 4 by fastening the electric wire receiving part 4 and the electric wire presser part 3 with nuts 7 and 8, to hold the electric wire D. An isolation part 2 has a wire receiving part 10 standing from the electric wire fitting part 1, and a wire presser part 11 provided at an upper part of the wire receiving part 10, which freely opens and closes in a horizontal-axis rotatable manner. The wire receiving part 10 is provided with a plurality of wire hook parts 13 at intervals in a vertical direction, and has a part to be fitted 23. The wire presser part 11 has a fitting part 21 to be fitted to the part to be fitted 23 when closed so as to fit the wire receiving part 10, and surrounds a wire W held at the wire hook part 13 by the closed wire receiving part 10 and the wire presser part 11 in an inseparable manner.COPYRIGHT: (C)2014,JPO&INPIT【課題】鳥の体長に対応して電線とワイヤー間の位置調整を行える鳥害防止具の提供。【解決手段】電線取付部1は、電線Dの一端部を保持する電線受け部4と、電線受け部4の上部に水平軸回転自在に軸支し、電線Dの他端部を保持する電線押さえ部3と、電線受け部4と電線押さえ部3とをナット7,8で締め付け電線受け部4を引き寄せて、電線Dを挟持する締付部5とを有し、離隔部2は、電線取付部1から起立するワイヤー受け部10と、ワイヤー受け部10の上部に水平軸回転で開閉自在のワイヤー押さえ部11を有し、ワイヤー受け部10は、上下に間隔をあけて複数のワイヤー掛け部13を設け、被嵌合部23を有し、ワイヤー押さえ部11は、ワイヤー受け部10と閉塞したときに被嵌合部23と嵌合する嵌合部21を有し、閉塞したワイヤー受け部10とワイヤー押さえ部11との間でワイヤー掛け部13に保持したワイヤーWを囲んで離脱不能とする。【選択図】図1
