2. Description of the Related Art In general, birds, especially pigeons, have a habit of stopping at a beam in a building, a lower surface edge outside a window opening, a rooftop edge, and the like, and a structure stops when a pigeon rests. It is a great place to go. When the pigeon stops, pigeon droppings are left on the structure, but the pigeon droppings damage the appearance of the structure, oxidize and corrode the structure, contaminate it, and spread the pathogens to the human body. The substance has an adverse effect and produces an odor. In addition, flying pigeons generate noise. For this reason, bird damage such as fecal pollution has become a social problem in recent years, and excellent bird-proofing equipment has been eagerly sought.

[0003] As a conventional bird-proofing device, for example, a metal sword or a wire such as stainless steel having a length of about 100 mm to 150 mm is placed on a plate-like or substantially lattice-like base portion for 30 m.
Some birds are erected at intervals of about m to 40 mm, and the bird-proofing equipment is installed at the lower edge of the outside of the window opening or on the edge of the roof, and exhibits a bird-proofing function. However, the sword mountain and the wire may skew the pigeon that has come to the edge, and the carcass of the pigeon may impair the aesthetics of the building and require labor for maintenance. The wire may be bent by the load of the flying pigeon, which may reduce the bird-proofing effect and impair the aesthetic appearance of the edge. When the wire is thick, the wire is noticeably unsightly and dust tends to adhere.

[0004] In order to alleviate the above-mentioned difficulties to some extent, for example, a bird-proofing device as shown in FIG. 3 has been proposed. The bird-proofing device 1 is arranged on the substantially lattice-like base 2 in a range of 100 mm to 150 mm.
3 mm thick plastic sword mountain and 3 mm thick needle
It is erected at an interval of about 0 mm to 40 mm, and the head 3a of the plastic sword mountain 3 is formed in a rounded spherical shape. And so on. The birdproofing device 1 can prevent a flying dove from being skewered into the sword mountain and bending the sword mountain, so that the appearance of the building is not impaired by the dead body or the bent wire.

[0005]

However, although the bird-proofing device 1 using the plastic sword mountain 3 or the like exhibits a bird-proofing function for a certain period of time after being installed, the learning function of a pigeon or the like becomes accustomed to it. The pigeons that have recognized that there is no danger come flying regardless of the plastic
There is a problem that the birds are straddled on the top and the bird-proof function is not exhibited. For this reason, there has been a long-felt need for a bird-proofing instrument that can exhibit an excellent bird-proofing function semipermanently and that does not impair the aesthetics of a building.
