PROBLEM TO BE SOLVED: To provide an electric wire attachment tube capable of reducing wind force applied to an electric wire even when being attached thereto and also being molded in a stable form, and a bird damage prevention member attached to the electric wire attachment tube.SOLUTION: An electric wire attachment tube 1 comprises a folded-back portions 12 which are folded back on the outer surface of a cylindrical body 10. Compared to a conventional electric wire attachment tube in which a body opening portion is extended in a radial direction from the outer surface of the cylindrical body, the electric wire attachment tube 1 has a smaller exposed area to the wind, and further, is stabilized because the folded-back portions 12 act as weights by the folded back structure, preventing swinging of the electric wire after the electric wire attachment tube 1 is attached thereto. By this, comparing force received when the electric wire onto which the electric wire attachment tube is attached is exposed to the wind, the electric wire attachment tube 1 can greatly reduce force received by the electric wire when exposed to the wind, compared to the conventional electric wire attachment tube. Moreover, the electric wire attachment tube 1 is formed so that the entire structure has a uniform thickness therefore, contraction of the entire structure becomes uniform upon cooling and the electric wire attachment tube 1 does not deform in an arched shape, and can be molded in a stable shape.COPYRIGHT: (C)2013,JPO&INPIT【課題】電線に取り付けても電線にかかる風の力を低減し、かつ、安定した形状で成型ができる電線取付管、及び、この電線取付管に取り付けられる鳥害防止具部材を提供する。【解決手段】この電線取付管1は、折返部12が筒状本体10の外部表面に折り返されているので、開腹部が筒状本体の外部表面から径方向に沿って延設された従来の電線取付管と比較して受風面積が小さく、しかも、この折返しによって折返部12が錘となり安定するため、電線に取り付けた後、風を受けても揺動しない。そのため、電線取付管が取り付けられた電線が受風時に受ける力を比較した場合、本実施形態の電線取付管1は、従来の電線取付管に比べ、電線が受風時に受ける力を大幅に低減することができる。また、この電線取付管1は、全体が同じ厚みで形成されているので、冷却時に均一に収縮し弓なりに曲がって変形しないので安定した形状で成型することができる。【選択図】図1
