It has a repellent effect because it does not exist, but the cylindrical rotating roller can be freely rotated on the support member. Since the structure is only supported, the bird stops right above the rotating roller and the balun works well. The rotating roller may not rotate if you take a bird, so a bird that has learned this sense of balance. In that case, you can continue to stop, so the repellent effect does not last long.

[0006]   In addition, the bird damage prevention device described in Patent Document 2 has a protrusion on the outer upper part of the rotatable tube. Is provided on the tip side of this protrusion, and the protrusion protrudes in a direction displaced from the center line of rotation of the pipe body. Since a bird is provided in this bent part, the balance is inevitably lost when a bird stops at this bent part. The projections rotate with the tube to surprise the bird. This Therefore, a more reliable rotation operation than the bird avoiding device described in Patent Document 1 can be obtained. In the machine, the function of the projection with the bent portion is always located at the upper part of the pipe body, In other words, even if the protruding part may rotate due to a bird stopping, etc., it is necessary after that. Since the protruding part has a function to return to the upper part of the tube, it stops several times and this fixed position Birds that have learned a sense of balance that keeps the child can continue to stop The effect does not last long. In addition, the pipes that make up this bird damage prevention device pipe are supported by the distribution line. Since it is designed to rotate, it will rotate smoothly when the distribution line becomes loose. It will not roll and the repellent effect will be lost.

[0007]   On the other hand, the bird damage prevention device described in Patent Document 3 has a plurality of blade bodies provided in a cylindrical body. It is designed to surprise the bird by rotating it with wind force and prevent the bird from flying. Therefore, if the wind is weak and the blade does not rotate, the bird repellent effect cannot be obtained. Also However, when the blade is rotating due to wind force, operating noise is generated, so noise is not desired. It is not possible to use it in places where
