  As described above, the nesting prevention tool 2 (first embodiment) includes the receiving tool 23, the bolt 241, and the nut 242. The receiver 23 receives the nest 22 of either one of a nest made of a bird, for example, a crow in a first place and an artificial nest. The bolts 241 and the nuts 242 are used to attach the receiving device 23 to a second location on the utility pole 11 that is different from the first location described above. Therefore, it is possible to prevent the crow from nesting with respect to the utility pole 11 based on the behavior of the crow described above. Also, if the nest 22 is a nest made at a first location by a crow, the crow that created the nest 22 has moved the second nest 22 from the first location to the second location. It may become impossible to recognize that the nest 22 provided in the place is a nest created by the user. In this case, it is possible to prevent the crow that has formed the nest 22 from nesting in the utility pole 11.

  Further, a first insertion hole 231 is formed in the receiver 23. The bolt 241 is inserted through the first insertion hole 231 and the second insertion hole 131 formed in the arm metal 13 so as to penetrate along the longitudinal direction (z axis) of the utility pole 11.

Therefore, it is possible to provide the nesting prevention tool 2 that can be attached relatively easily by the bolt 241 and the nut 242.

  The bolt 241 is inserted through the first insertion hole 231 and the second insertion hole 131 so that the head of the bolt 241 is provided on the upper part of the arm metal 13. Therefore, the tip of the bolt 241 opposite to the head can be prevented from protruding to the upper side (+ z) of the nest 22. Therefore, it is possible to simulate the nest made on the brace 13 by the crow. Therefore, it is possible to reliably prevent crows from nesting with respect to the utility pole 11.

  The receiver 23 includes a first wire 232 and a second wire 233. The first wire 232 is bent in an annular shape so that the first insertion hole 231 is formed. The plurality of second wire rods 233 extend radially from the first wire rod 232 toward the side (+ z) opposite to the arm metal 13 so that the nest 22 is held inside the receiver 23. Therefore, for example, the nest 22 can be securely attached to the brace 13 so that the nest 22 is not blown off by wind.

  Moreover, the receiving device 23 is colored brown. Therefore, it is possible to reliably prevent nesting by crows by simulating a nest made of twigs by crows, for example.

  The model 21 is provided on the nest 22. Therefore, nesting by the crow can be reliably prevented by simulating the presence of the crow in the nest 22.

  The first to third embodiments are for facilitating understanding of the present invention, and are not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof.

  In 1st Embodiment, although demonstrated that the nest 22 was a crow's nest, it is not limited to this. For example, the nest 22 may be a bird's nest other than a crow.
