This bird harm prevention tool includes a base portion 11 and a needle-like portion 12 extending from the base portion 11. The base 11 includes a plurality of (in this example, nine) holding portions 13 arranged along the longitudinal direction of the elongated body (the left-right direction in FIG. 1, hereinafter referred to as the axial direction), and the holding portions 13 as axes. The communication part 14 connected along a direction is provided. The needle-like part 12 can project from both the holding part 13 and the connecting part 14, but in this example, the needle-like part 12 projects only from the holding part 13. The needle-like part 12, the holding part 13, and the connecting part 14 are implemented as an integrally molded product of synthetic resin, but any part may be formed as a separate body and assembled after being formed.

The holding unit 13 includes a receiving portion 21 that receives the aerial elongated body, and an opening portion 22 for inserting the aerial elongated body into the receiving portion 21. Specifically, the holding portion 13 includes a receiving portion 21 that is an incomplete annular body by cutting out a part of a cylindrical body that is relatively short in the axial direction, and includes one peripheral end 23 and the other periphery of the receiving portion 21. A space between the end 24 constitutes the opening portion 22. The opening portion 22 opens downward when attached to the elongated body. In this example, the receiving portion 21 is formed over a range of about 300 degrees, and the needle-like portions 12 are formed radially every 60 degrees. Of course, these angles, the number of needle-like portions 12 and the like can be changed as appropriate, and different angles and numbers can be set for each holding portion 13.

The inner diameter of the holding portion 13 is assumed to be substantially the same as the diameter of the long body, and it is desirable that the holding portion 13 does not rotate with respect to the long body in the mounted state. Even if it is a thing, it is possible to implement.

The connecting portion 14 may have a rigidity that cannot be deformed by a human hand, but it is desirable to provide flexibility that can be deformed by a human hand. In particular, as shown in FIG. 1B, it is desirable that the connecting portions 14 adjacent to each other in the axial direction be displaced in a direction intersecting with the axial direction. As a result, it is easy to bend in the direction intersecting the axial direction, and even a portion where the electric wire or the like is bent can easily be bent. In particular, it is possible to further improve the overall flexibility by arranging the connecting portions adjacent in the axial direction so as to be alternately shifted left and right and left and right in a direction orthogonal to the axial direction. Although not shown in the figure, the connecting portions 14 can be arranged in a straight line without being displaced.
