Then, the bolt 27 is screwed into the nut 26 through the elongated hole 24 and the bolt insertion hole 25 from the lower side of the connecting strip 23 to thereby connect the connecting strip 2.
3, the support member 105 is integrally fixed, and by loosening the bolt 27, the support member 105 can be slid and its position can be freely adjusted. A plurality of barrier rods 11, 11,... Slightly facing downward are provided on both sides of the support member 105 in parallel.

FIG. 13 shows the fourth and fifth nesting prevention devices A4 and A4.
It is a perspective view showing the example of use of A5. In this example of use, one arm bar B is protruded horizontally from a utility pole P, a tension insulator G is provided on the upper surface on the base end side, and a connection fitting C is mounted. A switch E is suspended below the tip of the arm B via a suspension D. Then, the mounting bracket 1 is attached to the arm B located above the switch E to provide the fourth nest preventing tool A4. In the fourth nesting prevention tool A4, the support member 104 is disposed so as to overlap the arm B, and a plurality of barrier rods 11 stand upright along the arm B. In addition, a fifth nesting prevention tool A5 is provided in the vicinity thereof so as to cover the upper surface of the switch E with the mounting bracket 1 similarly. In this way, since the plurality of barrier rods 11 are erected on the upper surface of the arm B, it is difficult for birds to nest, and even if a twig of a tree is dropped from above to nest on the upper surface of the switch E, even if these twigs are dropped from above. Will slide down the upper surface of the group of barrier rods 11 and be blocked, thereby preventing nesting. Further, each of the first to fifth nesting prevention tools A1 to A5 has a simple structure, is easy to manufacture, and can be provided at low cost. In addition, it goes without saying that the first to fifth nesting prevention tools A1 to A5 can be used in addition to the above-mentioned use examples.

[0021]

As described above, the nesting prevention device according to the present invention allows the mounting bracket to be attached to the arm bar fixed to the telephone pole without interfering with the pin insulator or the edging wire. It can be easily installed by attaching and fixing it. Moreover, by selecting and using a pin insulator and a supporting member having a length corresponding to the interval between the edging wires, it is possible to cover the vacant upper surface of the arm with a group of barrier rods that stand.
Birds can be prevented from flying and nesting. Also, for equipment such as switches and various other types of pole-mounted equipment, mounting brackets are attached to arms that are located above these equipment, and the upper surface is covered. By selecting a nesting prevention tool suitable for the installation location, it is possible to effectively prevent bird damage.
