PROBLEM TO BE SOLVED: To provide a bird damage prevention tool that can maintain an original bird damage prevention function and also can be easily fitted even to a curved bridle wire to have superior operability.SOLUTION: The bird damage prevention tool has a cylindrical body 1 molded of a synthetic resin material having electric insulating properties and formed by putting a pair of halved cylindrical bodies 1a, 1b one over the other. The halved cylindrical bodies 1a, 1b are composed of a pair of longitudinal rods 2a, 2b arranged at both edges parallel with their center axis line, and a plurality of lateral rods 3 arranged between both the longitudinal rods 2a, 2b while curved outward in an arch shape and arrayed at fixed intervals from each other along the pair of longitudinal rods 2a, 2b. Thin and long rod-like bodies 4 pointed along a normal direction extending from the center axis line O are implanted on outer peripheral surfaces of the longitudinal rods 2a, 2b and outer peripheral surfaces of the lateral rods 3, respectively.COPYRIGHT: (C)2013,JPO&INPIT【課題】本来の鳥害防止機能を維持できると同時に湾曲した縁回し線にも容易に取り付けられ作業性に優れる電線用鳥害防止具を提供する。【解決手段】電気絶縁性を有する合成樹脂材により成形され、一対の半割り筒体1a,1bを重ね合わせて形成される筒状本体1を有し、各半割り筒体1a,1bはその中心軸線と平行な両側縁に配置される一対の縦杆2a,2bと両縦杆2a,2b間に外側へアーチ状に湾曲して差し渡され該一対の縦杆2a,2bに沿って一定の間隔離して列設される複数の横杆3とからなり、縦杆2a,2bの外周面と横杆3の外周面とにそれぞれ中心軸線Oから延びる法線方向に沿って先端を尖らせた細長の棒状体4を植設してなる。【選択図】図2
