PROBLEM TO BE SOLVED: To provide an installed article fixing device capable of fixing an installed article such as a bird damage preventive tool provided on an outdoor aerial cable, so as not to move for a long term, without loosing by shaking due to strong wind and vibrations in a place with heavy traffic.SOLUTION: By forming a lower arm portion 3 and an upper arm portion 4, a body frame 1 having a generally C-shaped side surface is formed. A screw rod 5 is screwed so as to be vertical to the lower arm portion 3. A shaft-shaped portion 9 is protrusively provided at an upper end of the screw rod 5, and a ring body 10 formed so as to be expanded/contracted is loosely fitted with an outer periphery of the shaft-shaped portion 9. A receiving member 15 is supported on the ring body, and opposite surfaces 11 and 18 between the ring body and the receiving member are formed in a tapered shape gradually decreasing a diameter toward an upper side. By rotating the screw rod 5 and elevating the receiving member, a cable 20 is clipped, and at that time, the screw rod 5 presses the ring body 10, thereby contracting the diameter of the ring body and fastening the shaft-shaped portion 9.COPYRIGHT: (C)2013,JPO&INPIT【課題】屋外架空ケーブルに設けられる鳥害防止具等の装着品を、強風による揺れや交通の激しい場所の振動によって緩むことなく、長期にわたり移動不能に固定できる装着品固定装置を提供する。【解決手段】下方腕部3と上方腕部4を形成することにより側面略コ字形の本体フレーム1を形成し、ねじ棒5を下方腕部3に垂直に螺合し、ねじ棒5の上端に軸状部9を突設し、拡縮自在に形成されたリング体10を軸状部9の外周に遊嵌し、該リング体上に受部材15を支持し、該リング体と該受部材との対向面11,18を上方に向けて次第に細径となるテーパ状に形成し、ねじ棒5を回転させ受部材を昇降させることでケーブル20が挟持され、その際にねじ棒5がリング体10を押圧することで該リング体が縮径し軸状部9を締め付ける。【選択図】図1
