<p>PURPOSE:To prevent the rest of a bird for a long term without damaging a fine view by inserting a rotatable cylindrical body to an electric wire, etc., and turning the cylindrical body when the bird rests on the cylindrical body. CONSTITUTION:A bird-rest preventive tool 10 is formed in the shape of a cylindrical body 10b having a through-hole 10a, and eight projected ridges 10c-10j are arranged at regular intervals in the circumferential direction on the outer circumferential surface of the cylindrical body, and extended in parallel with the axis of the cylindrical body 10b. The diameter of the through-hole 10a is set at a value larger than the outside diameters of electric wires, etc., and the cylindrical body can be rotated around the electric wire, etc. The bird-rest preventive tool 10 can be expended in a plane shape by a parting line 10k, and divided in the plane shape and can be installed to the electric wire, etc. Accordingly, when a bird rests on the bird-rest preventive tool, the bird-rest preventive tool is turned around the electric wire, etc., thus preventing a rest on the bird-rest preventive tool of the bird.</p> |
