The reinforcing rib 20 has a guide edge 20a that is continuous with the opening 1a without a step and is formed in the vicinity of the opening 1a. The guide edge 20a slides on the circumferential surface a of the electric wire protection tube A, guides the electric wire protection tube A in the direction of the opening 1a, enters the inside of the holding member 1, and presses the holding member 1 from above. The opening 1a is formed so as to be enlarged in the left-right direction.

突片10は、開口部１ａに沿って左右一対に下方突出状に形成されている。左右一対の突片10，10の下方には各々に外方拡大状の勾配縁10ａが形成されている。
勾配縁10ａは、開口部１ａに段差無しで連続するように形成されている。また、電線保護管Ａの円周面ａに摺動して、電線保護管Ａを開口部１ａから挟部材１の内部に突入するように誘導すると共に、挟部材１を上方から押し付けることで開口部１ａを左右方向に拡大開口させるように形成されている。第４針部14のガイド縁20ａを挟むようにガイド縁20ａの前後位置に形成されている。つまり、挟部材１が斜上方から電線保護管Ａに取着される際に、ガイド縁20ａよりも先に、円周面ａに接触し、摺動して開口部１ａを左右方向に拡大するように形成されている。 The projecting pieces 10 are formed in a downward projecting shape along a left and right pair along the opening 1a. Below each of the pair of left and right projecting pieces 10, 10, an outwardly expanding gradient edge 10a is formed.
The gradient edge 10a is formed to be continuous with the opening 1a without a step. Moreover, it slides on the circumferential surface a of the electric wire protection tube A, guides the electric wire protection tube A into the inside of the pinching member 1 from the opening 1a, and presses the pinching member 1 from above to open it. The part 1a is formed so as to be enlarged in the left-right direction. It is formed at the front and rear positions of the guide edge 20a so as to sandwich the guide edge 20a of the fourth needle portion 14. That is, when the clamping member 1 is attached to the wire protection tube A from obliquely above, it contacts the circumferential surface a before the guide edge 20a and slides to expand the opening 1a in the left-right direction. It is formed as follows.

また、図３及び図４に於て、電線保護管Ａに取着する前の状態で、Ｃ字状の挟部材１の内周円弧の半径寸法を曲率半径Ｒとすると、挟部材１の曲率半径Ｒが相違する２種類のものを連結している。つまり、一方の挟部材１の曲率半径Ｒよりも他方の挟部材１の曲率半径Ｒを大きく形成している。
ここで、説明を容易にするために、一方の挟部材１の曲率半径Ｒを小曲率半径Ｒ1 とし、他方の挟部材１の曲率半径Ｒを大曲率半径Ｒ2 とする。さらに、小曲率半径Ｒ1 を有する一方の挟部材１を小挟部材１’とし、大曲率半径Ｒ2 を有する他方の挟部材１を大挟部材１”とする。 3 and 4, when the radius dimension of the inner circumferential arc of the C-shaped sandwiching member 1 is the curvature radius R before being attached to the wire protection tube A, the curvature of the sandwiching member 1 is as follows. Two types having different radii R are connected. That is, the curvature radius R of the other sandwiching member 1 is formed larger than the curvature radius R of one sandwiching member 1.
Here, for ease of explanation, it is assumed that the radius of curvature R of one clamping member 1 is a small curvature radius R 1 and the radius of curvature R of the other clamping member 1 is a large curvature radius R 2 . Further, one sandwiching member 1 having a small curvature radius R 1 is referred to as a small sandwiching member 1 ′, and the other sandwiching member 1 having a large curvature radius R 2 is referred to as a large sandwiching member 1 ″.

小挟部材１’の小曲率半径Ｒ1 は、小径の小電線保護管Ａの外周半径ｒよりも僅かに小さく形成されている。
また、大挟部材１”の大曲率半径Ｒ2 は、大径の大電線保護管Ａの外周半径ｒよりも僅かに小さく形成されている。
つまり、挟部材１の内周円弧の曲率半径Ｒは、鳥類の飛来を防止すべき電線保護管Ａの外周半径ｒよりも僅かに小さく設定されている。 The small curvature radius R 1 of the small clamping member 1 ′ is formed slightly smaller than the outer peripheral radius r of the small-diameter small wire protection tube A.
Further, the large curvature radius R 2 of the large clamping member 1 ″ is formed slightly smaller than the outer peripheral radius r of the large-diameter large wire protection tube A.
That is, the radius of curvature R of the inner circumferential arc of the sandwiching member 1 is set slightly smaller than the outer radius r of the electric wire protection tube A that should prevent birds from flying.

小挟部材１’及び大挟部材１”は、電線保護管Ａの円周面ａに使用状態で当接する各々の内周円弧の内周上縁１ｅを、軸心方向Ｌから見て一致するように連設されている。つまり、小曲率半径Ｒ1 の中心と大曲率半径Ｒ2 の中心は同心状に配設されていない。また、小挟部材１’及び大挟部材１”の各針部（第１・２・３・４針部11，12，13，14）は、基準姿勢（電線保護管Ａに外嵌していない状態）で、軸心Ｌ方向から見て一致するように設けられている。また、大挟部材１”のガイド縁20ａは、小挟部材１’のガイド縁20ａよりも下方に突出して設けられている。
また、図１に示すように、小挟部材１’と大挟部材１”とを軸心Ｌ方向（前後方向）に交互に配設して連結杆２によって連結している。言い換えると、Ｃ字状の挟部材１の曲率半径Ｒが相違する２種類のものを交互に配設している。 The small sandwiching member 1 ′ and the large sandwiching member 1 ″ coincide with the inner circumferential upper edge 1 e of each inner circumferential arc that abuts the circumferential surface “a” of the electric wire protection tube A when used in the axial direction L. That is, the center of the small radius of curvature R 1 and the center of the large radius of curvature R 2 are not concentrically arranged. The needle portions (first, second, third, and fourth needle portions 11, 12, 13, and 14) coincide with each other when viewed from the direction of the axis L in the reference posture (in a state in which they are not externally fitted to the wire protection tube A). Is provided. Further, the guide edge 20a of the large clamping member 1 ″ is provided so as to protrude downward from the guide edge 20a of the small clamping member 1 ′.
Further, as shown in FIG. 1, the small clamping members 1 ′ and the large clamping members 1 ″ are alternately arranged in the axial center L direction (front-rear direction) and connected by the connecting rod 2. In other words, C Two types of character-shaped sandwiching members 1 having different curvature radii R are alternately arranged.

And are attached to the respective locking projections 40b of the left and right connecting portions 40, 40. Further, when packing, it can be packed and stored so that the locking hole portion is attached to the locking protrusion 40b. In addition, the corrugated plate shape provides strength and flexibility at a desired location. For example, a portion disposed in a curved shape below the wire protection tube A is formed in a wave shape. Moreover, since it is plate-shaped, it is accommodated without requiring a dedicated space for packing. Moreover, the drop-off prevention member of another example of the embodiment is configured such that the wire protection tube A rotates around the axis L by connecting the sandwiching member 1 in the left-right direction across the lower portion of the wire protection tube A. Even when a force (load) in the drop-off direction is applied so that 1a faces upward, the drop-off is prevented.

上述した本発明の電線保護管用鳥類飛来防止装置（本装置）の作用（使用方法）について説明する。
図８に於て、上下方向に複数積み重ねられる収納状態（又は梱包状態）の際に、下方の挟部材１の第１針部11の頂部は、上方に配設される別の挟部材１の第１針部11の収納空洞部11ｂに挿入される。下方の挟部材１の段付面11ａが上方の挟部材１の内周円弧に当接して、第１針部11の段付面11ａより基端側部が収納空洞部11ｂに入り込むのを規制する。また、第１針部11の頂部近傍の先端面と収納空洞部11ｂの内周面との間に間隙部を形成する。第１針部11の円錐状の先端テーパー部が収納空洞部11ｂの内壁にくさび状に面接触するのを防止する。つまり、下方の挟部材１の第１針部11が上方の挟部材１の収納空洞部11ｂに食い込むように挿入されるのを防止する。即ち、梱包から取り出す際に、収納空洞部11ｂから第１針部11が容易に分離される。 The operation (usage method) of the above-described bird flying prevention apparatus (this apparatus) for an electric wire protective tube of the present invention will be described.
In FIG. 8, the top portion of the first needle portion 11 of the lower sandwiching member 1 is in the state of another sandwiching member 1 disposed above in the storage state (or packed state) where a plurality of stacks are stacked in the vertical direction. The first needle portion 11 is inserted into the storage cavity portion 11b. The stepped surface 11a of the lower pinching member 1 is in contact with the inner circumferential arc of the upper pinching member 1, and the proximal end side portion of the stepping surface 11a of the first needle portion 11 is prevented from entering the storage cavity 11b. To do. Further, a gap is formed between the tip surface near the top of the first needle portion 11 and the inner peripheral surface of the storage cavity portion 11b. The conical tip tapered portion of the first needle portion 11 is prevented from coming into surface contact with the inner wall of the storage cavity portion 11b in a wedge shape. That is, the first needle portion 11 of the lower holding member 1 is prevented from being inserted so as to bite into the storage cavity portion 11b of the upper holding member 1. That is, when taking out from a package, the 1st needle part 11 is easily isolate | separated from the storage cavity part 11b.

また、段付面11ａに、上方の挟部材１が当接することで、上方の本装置と下方の本装置が上下方向に所定の間隔をもって、積み重ねられる。所定の間隔によって、上方の本装置の突片10及び補強リブ20さらに接続部40等は、収納状態で、下方の本装置に干渉しない。 上方の大挟部材１”の突片10及び接続部40のガイド突片40ｃは、下方の第１挟枠部１Ａと第２挟枠部１Ｂとの間の窓部１Ｄに挿入乃至挿通される。また、第２針部12と第３針部13と第４針部14は、前後方向に離れた位置から各々突出しているので、相互に干渉させず上下方向にコンパクトに積み重ねられる。例えば、第２針部12と第３針部13及び第４針部14が同円弧上に突設されたとすると、上下に積み重ねた際に、上方の本装置の第３針部13及び第４針部14に下方の本装置の第２針部12が干渉し、上下にコンパクトに積み重ねるのが困難となる。つまり、本装置は、斜下方に突出する（下方傾斜状の）第４針部14を有しながらも（複数の針部を放射状に有しながらも）、上下にコンパクトに積み重ねて収納される。   Further, when the upper sandwiching member 1 is brought into contact with the stepped surface 11a, the upper apparatus and the lower apparatus are stacked at a predetermined interval in the vertical direction. Due to the predetermined interval, the protruding piece 10 and the reinforcing rib 20 of the upper apparatus, the connecting portion 40 and the like do not interfere with the lower apparatus in the housed state. The protruding piece 10 of the upper large clamping member 1 ″ and the guide protruding piece 40c of the connecting portion 40 are inserted or inserted into the window portion 1D between the lower first clamping frame portion 1A and the second clamping frame portion 1B. Further, since the second needle portion 12, the third needle portion 13, and the fourth needle portion 14 protrude from positions separated in the front-rear direction, they are stacked in a vertical direction without causing interference with each other. Assuming that the second needle portion 12, the third needle portion 13 and the fourth needle portion 14 are projected on the same arc, the upper and lower third needle portions 13 and 13 of the present apparatus when stacked vertically. The second needle portion 12 of the lower device interferes with 14 and it is difficult to stack compactly up and down, that is, the device has a fourth needle portion 14 that projects obliquely downward (inclined downward). While having (even having a plurality of needles radially), they are stored in a compact stack up and down.

また、上下方向に積み重ねられた際に、最も下方に配設される本装置の複数の挟部材１（小挟部材１’及び大挟部材１”）の各第４針部14が脚部となって上方に配設される複数の本装置の荷重を支持する。左右一対に下方傾斜状に突出した第４針部14は、積み重ねられた本装置が倒れたり横転するのを防止し、安定した状態を保持する。   Further, when stacked in the vertical direction, the fourth needle portions 14 of the plurality of sandwiching members 1 (small sandwiching member 1 ′ and large sandwiching member 1 ″) of the present apparatus disposed at the lowest position are the leg portions. The fourth needle part 14 projecting downwardly in a pair of left and right sides prevents the stacked apparatus from falling down or overturning, and is stable. Hold the state.

また、第４針部14に形成された補強リブ20によって、上方からかかる荷重を第４針部14が受ける際に、左右一対の第４針部14が左右方向に広がり変形するのを防止する。言い換えると、最下段（最下方）の本装置が開口状に押し潰れるように変形するのを防止する。   Further, the reinforcing rib 20 formed on the fourth needle part 14 prevents the pair of left and right fourth needle parts 14 from spreading in the left-right direction and deforming when the fourth needle part 14 receives a load from above. . In other words, the lowermost (lowermost) apparatus is prevented from being deformed so as to be squeezed into an opening.

次に、図２に於て、電線保護管Ａに連結杆２を軸心Ｌと平行かつ長手方向を一致させて上方から押し込むように取着する際に、挟部材１を上方から押し込むと、突片10の勾配縁10ａ及び第４針部14の補強リブ20に形成されたガイド縁20ａが、電線保護管Ａをスムーズに開口部１ａ近傍に案内（ガイド）する。さらに、挟部材１を押し込むと、勾配縁10ａ及びガイド縁20ａが円周面ａに摺動し、挟部材１の開口部１ａが自ら開口するように拡大する。挟部材１は弾性変形し、電線保護管Ａに抱き込み状に取着される（電線保護管Ａを挟持する）。挟部材１は電線保護管Ａに外嵌する。挟部材１の複数の針部（第１・２・３・４針部11，12，13，14）は、電線保護管Ａの周囲に放射状に配設され、電線保護管Ａへの鳥類の飛来を防止する。   Next, in FIG. 2, when the connecting rod 2 is attached to the electric wire protection tube A so as to be pushed in from the upper side in parallel with the axial center L and aligned in the longitudinal direction, the clamping member 1 is pushed in from the upper side. The guide edge 20a formed on the gradient edge 10a of the projecting piece 10 and the reinforcing rib 20 of the fourth needle portion 14 smoothly guides (guides) the wire protection tube A in the vicinity of the opening 1a. Further, when the clamping member 1 is pushed in, the gradient edge 10a and the guide edge 20a slide on the circumferential surface a, and the opening 1a of the clamping member 1 expands so as to open itself. The pinching member 1 is elastically deformed and is attached to the electric wire protection tube A in a hug shape (holds the electric wire protection tube A). The sandwiching member 1 is fitted on the electric wire protection tube A.

即ち、本装置は、外周半径ｒの異なる２種類の電線保護管Ａに取着され、鳥類の飛来を防止する。 In FIG. 11, when attached to the large wire protection tube A, the opening 1a of the small pin 1 'is greatly elastically deformed and attached so as to cover the circumferential surface a of the large wire protection tube A. . The large clamping member 1 ″ is sandwiched and attached (clamped) so as to cover along the outer peripheral surface a of the large electric wire protection tube A. That is, the present apparatus is easily attached to the large electric wire protection tube A. .
The projecting piece 10 of the large clamping member 1 "is disposed so as to sandwich both the left and right sides of the protruding piece Ab of the large wire protection tube A. Only the large clamping member 1" is restricted from rotating around the axis L. . A plurality of needle portions (first, second, third and fourth needle portions 11, 12, 13, 14) of the small clamping member 1 ′ and the large clamping member 1 ″ are arranged radially around the wire protection tube A, Prevents birds from flying into the large wire protection tube A.
That is, this apparatus is attached to two types of wire protection tubes A having different outer peripheral radii r to prevent birds from flying.

図12に於て、電線保護管Ａが捩じれた（捻転した）ように変形した際は、電線保護管Ａの突出片Ａｂが挟部材１の突片10に当接し、捻じり変形方向に本装置を誘導する。複数の挟部材１を連結す連結杆２が捻じり変形可能であるので、本装置は電線保護管Ａの捩じれに追従するように捩じれる。挟部材１は電線保護管Ａに外嵌した状態で追従する。連結杆２は電線保護管Ａの捩じれ具合に柔軟に対応して捩じれる。挟部材１は、電線保護管Ａを挟持する状態が保持され、離脱を防止される。同様に、本装置を取着する前に電線保護管Ａが捩じれ変形していても、本装置は追従するように外嵌する。   In FIG. 12, when the electric wire protection tube A is deformed so that it is twisted (twisted), the protruding piece Ab of the electric wire protection tube A comes into contact with the protruding piece 10 of the sandwiching member 1, and the main wire is deformed in the direction of twisting deformation. Guide the device. Since the connecting rod 2 connecting the plurality of sandwiching members 1 can be twisted and deformed, the present apparatus is twisted so as to follow the twist of the wire protection tube A. The pinching member 1 follows in a state of being externally fitted to the electric wire protection tube A. The connecting rod 2 is twisted flexibly corresponding to the twisted state of the wire protection tube A. The sandwiching member 1 is held in a state of sandwiching the electric wire protection tube A and is prevented from being detached. Similarly, even if the wire protection tube A is twisted and deformed before the present apparatus is attached, the present apparatus is fitted so as to follow.

また、複数の針部を電線保護管Ａの周囲に放射状に配置しているので、軸心Ｌ廻りに複数の針部の左右一方側が傾倒するような際であっても（傾倒状となても）、複数の針部の左右の他方側が起立して（起立状となって）、左右方向や斜上方向及び上方向からの鳥類の飛来を防止する。
例えば、電線保護管Ａが略45度捩じれたような位置では、電線保護管Ａが自然姿勢の際に上方からの鳥類の飛来を防止していた本装置の第１針部11が上傾斜状となり、斜上方からの鳥類の飛来を防止する。また、左右の内一方の第２針部12は、上方を向いて、上方からの鳥類の飛来を防止する。また、左右の内一方の第３針部13は、斜上方に向いて（上方傾斜状となって）、斜上方からの鳥類の飛来を防止する。 Further, since the plurality of needle portions are arranged radially around the electric wire protection tube A, even when the left and right sides of the plurality of needle portions are tilted around the axis L (become tilted). Also, the other side of the left and right sides of the plurality of needle portions rises (becomes upright) to prevent birds from flying from the left-right direction, the obliquely upward direction, and the upward direction.
For example, at a position where the wire protection tube A is twisted by approximately 45 degrees, the first needle portion 11 of the present device that prevented the birds from flying from above when the wire protection tube A is in a natural posture is inclined upward. This prevents birds from flying obliquely from above. Moreover, the second needle part 12 on one of the left and right faces upward to prevent birds from flying from above. Further, the third needle portion 13 on one of the left and right faces obliquely upward (becomes upwardly inclined) and prevents birds from flying obliquely upward.

また、電線保護管Ａが、軸心Ｌ廻りに天地が反対になるように回転した際は、（基準姿勢で下傾斜状の）第４針部14が上方傾斜状となって、鳥類の飛来を防止する。また、上述した、（基準姿勢で下方突出状の）増設針部30ｃを有する脱落防止部材30を接続しておけば、増設針部30ｃが上方を向いて、上方からの鳥類の飛来を防止する。   Further, when the wire protection tube A is rotated around the axis L so that the top and bottom are opposite, the fourth needle portion 14 (inclined downward in the reference posture) becomes upwardly inclined, and birds fly. To prevent. In addition, if the above-described drop-off preventing member 30 having the additional needle portion 30c (projecting downward in the reference posture) is connected, the additional needle portion 30c faces upward to prevent birds from flying from above. .

なお、本発明は、設計変更可能であって、例えば、第１針部11は、第２挟枠部１Ｂと連結杆２との交差部に設けても良い。また、第２針部12を第１挟枠部１Ａに設け、第３針部13を第２挟枠部１Ｂに設けても良い。また、第１・２・３・４針部11，12，13，14の形状は角錐形状等、鳥類の飛来を防止可能な形状であれば良い。   The design of the present invention can be changed. For example, the first needle portion 11 may be provided at the intersection of the second sandwiching frame portion 1B and the connecting rod 2. Further, the second needle portion 12 may be provided in the first sandwiching frame portion 1A, and the third needle portion 13 may be provided in the second sandwiching frame portion 1B. The first, second, third, and fourth needle portions 11, 12, 13, and 14 may have any shape that can prevent birds from flying, such as a pyramid shape.

以上のように、本発明は、電線保護管Ａに着脱自在に外嵌されると共に電線保護管Ａが突入する開口部１ａが形成されているＣ字状の第１挟枠部１Ａと第２挟枠部１Ｂとを有し、第１挟枠部１Ａと第２挟枠部１Ｂとを開口部１ａ近傍で電線保護管Ａの軸心Ｌ方向に連結する連結部１Ｃを有する挟部材１を備え、挟部材１を軸心Ｌ方向に複数配設し、挟部材１の上部１ｂを貫通して連結する１本の捻じり変形可能な連結杆２を具備し、挟部材１は、連結杆２との交差部から垂直状に突出する第１針部11と、挟部材１から斜上方に突出する第２針部12と、挟部材１から左右水平方向に突出する第３針部13と、挟部材１から斜下方に突出する第４針部14と、を有するので、電線に装着済みの電線保護管Ａに容易かつ迅速に取着できる。また、円周面ａを第１・２挟枠部１Ａ，１Ｂが弾性変形によって抱き込み状に取着するので、脱落するのを防止できる。鳥類の飛来を防止する複数の針部（第１・２・３・４針部11，12，13，14）を放射状に設けているので、電線保護管Ａが捩じれたり回転しても、確実に鳥類が飛来するのを防止できる。また、多数の針部で鳥類の飛来を防止できる。   As described above, according to the present invention, the C-shaped first sandwiching frame portion 1A and the second C-shaped first frame portion 1A, which are detachably fitted to the wire protection tube A and in which the opening portion 1a into which the wire protection tube A enters, are formed. A sandwiching member 1 having a sandwiching frame portion 1B and having a connecting portion 1C that couples the first sandwiching frame portion 1A and the second sandwiching frame portion 1B in the axial center L direction of the wire protection tube A in the vicinity of the opening 1a. A plurality of pinching members 1 are arranged in the direction of the axis L, and a single twisting deformable connecting rod 2 is provided which penetrates and connects the upper portion 1b of the pinching member 1; A first needle portion 11 projecting vertically from the intersection with 2, a second needle portion 12 projecting obliquely upward from the pinching member 1, and a third needle portion 13 projecting horizontally from the pinching member 1 The fourth needle portion 14 projecting obliquely downward from the sandwiching member 1 can be easily and quickly attached to the wire protection tube A that has been attached to the wire. Further, since the first and second sandwiching frame portions 1A, 1B are attached to the circumferential surface a by elastic deformation, it can be prevented from falling off. Multiple needles (first, second, third and fourth needles 11, 12, 13, 14) that prevent birds from flying in are provided radially, so even if the wire protection tube A is twisted or rotated It is possible to prevent birds from flying in. Moreover, the flying of birds can be prevented with a large number of needle portions.

また、開口部１ａ近傍に設けた第４針部14に、変形を規制する補強リブ20を設け、補強リブ20は、開口部１ａに段差無しで連続して電線保護管Ａを誘導するガイド縁20ａを開口部１ａの近傍に形成しているので、電線保護管Ａの円周面ａに、ガイド縁20ａが摺接して、電線保護管Ａにスムーズに取着できる。また、開口部１ａを円周面ａに沿うように開口させることができる。つまり、挟部材１を電線保護管Ａ方向に押し込むようにすることで、挟部材１は自ら開口部１ａが開いて僅かな力で容易に取着できる。また、収納状態で上下に積み重ねても、斜下方に突出する第４針部14を脚部として使用でき、転がるようなことがなく安定して収納（梱包）できる。また、第４針部14が押し広げられる力を受けて変形するのを防止できる。   The fourth needle portion 14 provided in the vicinity of the opening 1a is provided with a reinforcing rib 20 that restricts deformation, and the reinforcing rib 20 guides the wire protection tube A continuously without any step to the opening 1a. Since 20a is formed in the vicinity of the opening 1a, the guide edge 20a is in sliding contact with the circumferential surface a of the wire protection tube A, and can be smoothly attached to the wire protection tube A. Moreover, the opening part 1a can be opened so that the circumferential surface a may be followed. That is, by pressing the clamping member 1 in the direction of the electric wire protection tube A, the clamping member 1 can be easily attached with a slight force by opening the opening 1a itself. Further, even when stacked up and down in the stored state, the fourth needle portion 14 protruding obliquely downward can be used as a leg portion, and can be stably stored (packed) without rolling. Further, it is possible to prevent the fourth needle portion 14 from being deformed due to the force that is pushed and spread.

また、第１針部11は、段付面11ａを有する段付突出形状に形成されているで、第１針部11を、収納空洞部11ｂに挿入しても、段付面11ａが内周面に当接して、所定の長さ以上挿入されるのを防止する。つまり、第１針部11が収納空洞部11ｂにくさび状に入り込んで面接触し、上下に収納した２つの電線保護管用鳥類飛来防止装置同士が喰い付くように収納されるのを防止する。つまり、梱包状態から取り出す際に、電線保護管用鳥類飛来防止装置を１つずつ容易に取り出せる。また、上下方向に所定の間隔をもって収納できる。   Further, since the first needle portion 11 is formed in a stepped protruding shape having a stepped surface 11a, even if the first needle portion 11 is inserted into the storage cavity portion 11b, the stepped surface 11a remains on the inner periphery. Abutting on the surface prevents insertion of a predetermined length or more. That is, the first needle portion 11 enters the storage cavity portion 11b in a wedge shape and comes into surface contact with the first needle portion 11 to prevent the two wire protection tube bird flying prevention devices stored up and down from being stowed. That is, when taking out from a packing state, the bird protection apparatus for electric wire protection tubes can be taken out one by one easily. Further, it can be stored at a predetermined interval in the vertical direction.

また、１本の連結杆２に沿って、Ｃ字状の上記挟部材１の曲率半径Ｒが相違する２種類のものを交互に配設したので、１種類の本発明の電線保護管用鳥類飛来防止装置（本装置）で、外径（外周半径ｒ）の異なる２種類の電線保護管Ａに取着できる。２種類の電線保護管Ａに鳥類が飛来するのを防止できる。電線保護管Ａのサイズ（大きさ）を確認してから本装置を用意する必要がなく、迅速に施工（取着）できる。   In addition, since two types of C-shaped sandwiching members 1 having different radii of curvature R are alternately arranged along one connecting rod 2, one type of bird for wire protection tube according to the present invention arrives. The prevention device (this device) can be attached to two types of wire protection tubes A having different outer diameters (peripheral radius r). Birds can be prevented from flying into the two types of wire protection tubes A. It is not necessary to prepare this apparatus after confirming the size (size) of the electric wire protection tube A, and it can be quickly constructed (attached).

また、挟部材１は、開口部１ａから下方へ突出する一対の突片10，10を有し、突片10に、開口部１ａ方向へ電線保護管Ａを誘導する勾配縁10ａが形成されているので、連結されている複数の挟部材１を１つずつ電線保護管Ａに取着できる。電線保護管Ａの斜め上方向からであっても開口部１ａをスムーズに開口させてこじれることなく容易に取着できる。   Further, the sandwiching member 1 has a pair of projecting pieces 10 and 10 projecting downward from the opening 1a, and the projecting piece 10 is formed with a gradient edge 10a for guiding the wire protection tube A in the direction of the opening 1a. Therefore, the plurality of pinched members 1 connected to each other can be attached to the wire protection tube A one by one. Even from the obliquely upward direction of the electric wire protection tube A, the opening 1a can be easily attached without being smoothly opened.

また、連結される複数の挟部材１の所定数毎に、脱落防止部材30を着脱可能な接続部40を、開口部１ａ近傍に設けているので、脱落をより確実に防止できる脱落防止部材30を取着できる。針部を増設するような追加部材（針部増設部材）を取着できる。   Moreover, since the connection part 40 which can attach or detach the drop-off prevention member 30 is provided in the vicinity of the opening 1a for every predetermined number of the plurality of sandwiching members 1 to be connected, the drop-off prevention member 30 which can prevent the drop-off more reliably.
