<p>PROBLEM TO BE SOLVED: To provide a nesting preventing device for a power pole which can be fixed without restriction to even the narrow space of an arm installed on the power pole. SOLUTION: Projecting pieces are oppositely provided on the outer sided of the divided end of the half cylinder 3 of a prescribed length and many needle bar bodies are projected at the surface of the half cylindrical body to form a nesting preventing barrier. Notches by the projecting pieces are provided at plural places and on the other hand, a folded and curved part 10 is stood upright at one end of a supporting arm 2 consisting of the belt plate of a prescribed length, and an arm fixing frame 11 fixed to the arm fixed to the power pole is provided at the lower surface of the other end of the supporting arm. Inserting and holding member obtained by extending polymerizing pieces 7b linearly at both ends of half- circular arc parts 7a are made to oppose each other to form an inserting and holding tool and a lower polymerizing piece 7c of the inserting and holding piece is polymerized to the folding and curving part of the supporting arm to connect with a bolt and nut 14. A button 8 and an engaging hole are oppositely provided at the upper polymerizing piece of the inserting, and holding tool to allow the notches of the barrier to insert and hold an internal bottom surface and to allow a circular arc part to insert and hold a half-divided cylinder. The button 8 and the engaging hole of the upper polymerizing piece are engaged to mount an arm supporting frame to the arm.</p> |
