Abstract

PROBLEM TO BE SOLVED: To provide an animal trapping cage capable of efficiently trapping a relatively-large wild animal.SOLUTION: An animal trapping cage is provided with: a rotating shaft 8 that is horizontally arranged on a bottom side of a cage body 1 and is supported rotatably; a bottom plate 9 that is attached to the rotating shaft 8 so as to form part of a bottom of the cage body 1; a rectangular frame 7 that woks as a stationary part facing a rotating tip of the bottom plate 9 when the bottom plate 9 faces a horizontal direction; and a support pin 10 that is laid between the rectangular frame 7 and the bottom plate 9 and horizontally supports the bottom plate 9. When an animal rides on the bottom plate 9 and then a moment equal to or more than a prescribed value is applied to the bottom plate 9, the support pin 10 is folded, the bottom plate 9 rotates, a release string 18 passing through a lower part of the bottom plate is pulled down and thereby fall doors 2 fall, and then apertures 1a on front and rear surfaces of the cage body 1 are closed. This animal trapping cage can efficiently trap a relatively-large animal because of no threats of working in response to a small animal not to be trapped.

Description

本発明は、比較的大型の野生動物を捕獲するための動物捕獲用檻に関する。 The present invention relates to an animal capture cage for capturing relatively large wild animals.

野生動物を捕獲するための動物捕獲用檻としては、前面および後面に開口が形成された檻本体と、檻本体の各開口の上方から落下することにより開口を閉じる一対の落下扉と、各落下扉を檻本体の開口の上方で保持する保持機構と、保持機構による落下扉の保持状態を解除するための解除機構とを備えたものがよく用いられているが、その檻本体内に動物が入ったときに解除機構を作動させる方法には種々のものがある。 As an animal trap for capturing wild animals, a trap body with openings formed on the front and rear surfaces, a pair of drop doors that close the opening by dropping from above each opening of the trap body, and each drop A door holding mechanism that holds the door above the opening of the cocoon body and a release mechanism for releasing the holding state of the falling door by the holding mechanism are often used. There are various ways to activate the release mechanism when it enters.

例えば、特許文献１で提案されている動物捕獲用檻では、檻本体の底板を回動可能に支持し、その底板上に動物が乗ったときに、底板が回動することにより、解除機構が作動して保持機構による各落下扉の保持状態が解除され、各落下扉が落下するようにしている。 For example, in the animal trapping cage proposed in Patent Document 1, the bottom plate of the cage main body is rotatably supported, and when the animal rides on the bottom plate, the bottom plate rotates to thereby release the release mechanism. The holding state of each drop door by the holding mechanism is released and each drop door is dropped.

ところで、上記特許文献１に記載された動物捕獲用檻は、解除機構の昇降部材を檻本体に付勢部を介して上下動自在に弾性支持し、この昇降部材を底板の回動先端部に連結することによって底板を支持している。このため、本来の捕獲対象ではない小動物が底板上に乗っても、付勢部の弾性により底板がある程度回動して解除機構が作動し、落下扉が落下して檻本体の前後面の開口を閉じてしまうおそれがある。そして、一旦檻本体の開口が閉じられると、再び動物の捕獲が可能な状態とするには、落下扉を持ち上げてその保持機構をセットしなおす必要があり、この保持機構の再セットに手間がかかるうえ、保持機構の再セットを行うまで本来の捕獲対象動物を捕獲できなくなる。すなわち、この動物捕獲用檻では、比較的大型の野生動物のみを捕獲しようとする場合、その捕獲対象の動物を効率よく捕獲することができないという問題がある。 By the way, in the animal trapping cage described in Patent Document 1, the lifting member of the release mechanism is elastically supported by the cage main body through a biasing portion so as to be movable up and down, and this lifting member is attached to the rotating front end portion of the bottom plate. The bottom plate is supported by connecting. For this reason, even if a small animal that is not the original capture target gets on the bottom plate, the bottom plate rotates to some extent due to the elasticity of the urging portion, the release mechanism operates, the falling door falls, and the front and rear surface openings of the cocoon body May be closed. Once the opening of the cage body is closed, it is necessary to lift the drop door and reset the holding mechanism to make it possible to capture the animal again. In addition, the original capture target animal cannot be captured until the holding mechanism is reset. That is, in this animal trap, when only a relatively large wild animal is to be captured, there is a problem that the capture target animal cannot be efficiently captured.

そこで、本発明は、比較的大型の野生動物を効率よく捕獲できる動物捕獲用檻を提供することを課題とする。 Therefore, an object of the present invention is to provide an animal trap that can efficiently capture relatively large wild animals.

上記の課題を解決するために、本発明は、前面および後面に動物が進入可能な開口が形成された檻本体と、前記檻本体の各開口の上方から落下することにより開口を閉じる一対の落下扉と、前記各落下扉を檻本体の開口の上方で保持する保持機構と、前記保持機構による落下扉の保持状態を解除するための解除機構とを備えた動物捕獲用檻において、前記檻本体の底側に水平に配され、回動可能に支持される回動軸と、前記檻本体の底部の少なくとも一部を形成するように前記回動軸に取り付けられる底板と、前記底板が水平方向を向いたときに底板の回動先端と対向する固定部と、前記固定部と底板との間に差し渡されて底板を水平に支持する支持ピンとを設け、前記底板上に動物が乗って底板に所定値以上のモーメントが加わったときに、前記支持ピンが折れ曲がって前記底板が回動軸と一体に回動することにより、前記解除機構が作動して前記保持機構による各落下扉の保持状態が解除され、前記各落下扉が落下して各開口が閉じられるようにした。なお、ここでの「水平」とは、本発明の動物捕獲用檻が上記課題を解決できる範囲で略水平であることを意味している（以下同じ）。 In order to solve the above-described problems, the present invention provides a pair of drops that closes the opening by dropping from above the openings of the cocoon body, and an eagle body in which an opening into which an animal can enter is formed on the front and rear surfaces. In the animal trapping cage comprising a door, a holding mechanism for holding each of the drop doors above the opening of the rod body, and a release mechanism for releasing the holding state of the drop door by the holding mechanism, A pivot shaft that is horizontally disposed on the bottom side of the casing and is rotatably supported, a bottom plate that is attached to the pivot shaft so as to form at least a part of a bottom portion of the main body, and the bottom plate is in a horizontal direction. A fixed portion that faces the rotating tip of the bottom plate when facing the surface, and a support pin that is interposed between the fixed portion and the bottom plate to horizontally support the bottom plate, and an animal rides on the bottom plate When a moment greater than the specified value is applied to When the support pin is bent and the bottom plate is rotated integrally with the rotation shaft, the release mechanism is operated to release the holding state of each drop door by the holding mechanism, and each drop door is dropped. Each opening was closed. Here, the term “horizontal” means that the animal capture cage of the present invention is substantially horizontal as long as the above-described problems can be solved (the same applies hereinafter).

上記の構成によれば、檻本体に入った動物が底板上に乗っても、その重量によって底板に生じるモーメントが所定値未満であれば、固定部と底板との間に差し渡された支持ピンが折れ曲がることなく底板を支持し続け、檻本体の前後面の開口が閉じられることはないので、比較的大型の（重量の大きい）動物のみを効率よく捕獲することができる。 According to said structure, even if the animal which entered the cage | basket body rides on a baseplate, if the moment which arises in a baseplate by the weight is less than predetermined value, the support pin passed between the fixing | fixed part and the baseplate Since it continues to support the bottom plate without being bent and the openings on the front and rear surfaces of the rod main body are not closed, only relatively large (heavy) animals can be captured efficiently.

また、具体的な構成としては、前記保持機構には、前記檻本体に回動可能に取り付けられ、所定姿勢で前記各落下扉を支持する一対の扉支持部材と、前記檻本体に係止される係止具と、一端を前記扉支持部材の一つに連結され、他端に設けた係止部が前記係止具に連結される一対の連結紐とを備えたものを採用するとともに、前記解除機構には、前記係止具の檻本体への係止状態を解除するための解除片と、一端が前記檻本体または固定部に固定され、他端が前記解除片に連結され、前記底板の下方を通過するように張られる解除紐とを備えたものを採用し、前記底板上に動物が乗って底板が回動したときに、前記底板が解除紐を押し下げて解除片を引っ張ることにより、前記係止具の檻本体への係止状態が解除され、前記係止具から各連結紐が外れて前記各扉支持部材の所定姿勢がくずれ、前記各落下扉が同時に落下するようにするとよい。 As a specific configuration, the holding mechanism is pivotally attached to the bag main body, and is locked to the bag main body and a pair of door support members that support the drop doors in a predetermined posture. And one end of which is connected to one of the door support members, and a locking portion provided at the other end is provided with a pair of connecting strings connected to the locking tool, In the release mechanism, a release piece for releasing the locking state of the locking tool to the heel body, one end is fixed to the heel body or the fixing portion, and the other end is connected to the release piece, A thing provided with the release string stretched so that it may pass under the bottom plate is adopted, and when the animal rides on the bottom plate and the bottom plate rotates, the bottom plate pushes down the release string and pulls the release piece. By this, the locking state of the locking tool to the heel body is released, and each connection from the locking tool Wherein a predetermined position of each door support member collapses unplugged, the may each fall door so as to fall at the same time.

本発明の動物捕獲用檻は、上述したように、底板上に動物が乗って底板に所定値以上のモーメントが加わったときに、底板を支持する支持ピンが折れ曲がって底板が回動することにより、檻本体の前後面の開口が閉じられるようにしたものであるから、軽量の小動物が底板上に乗っても開口を閉じることなく捕獲可能な状態を維持して、比較的大型の動物のみを効率よく捕獲することができる。 As described above, when the animal is placed on the bottom plate and a moment of a predetermined value or more is applied to the bottom plate, the support pin for supporting the bottom plate is bent and the bottom plate rotates as described above. Since the opening on the front and rear surfaces of the cocoon body is closed, even if a small light animal rides on the bottom plate, it maintains a state where it can be captured without closing the opening, and only relatively large animals can be captured. It can be captured efficiently.

以下、図面に基づき、本発明の実施形態について説明する。この動物捕獲用檻は、猪等の比較的大型の（重量の大きい）動物を捕獲対象とするもので、図１および図２に示すように、前面および後面に捕獲対象動物が進入可能な開口１ａが形成された檻本体１と、檻本体１の各開口１ａの上方から落下することにより開口１ａを閉じる一対の落下扉２、２と、各落下扉２を檻本体１の開口１ａの上方で保持する保持機構３と、保持機構３による落下扉２の保持状態を解除するための解除機構４と、檻本体１の底側にセットされる底板ユニット５とを備えている。そして、地面Ｇに設けた凹部Ｃに底板ユニット５をセットし、その周囲の地面Ｇ上に檻本体１を置いた状態で使用される。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. This animal-capturing cage is intended for capturing relatively large (heavy) animals such as cages, and as shown in FIGS. 1 and 2, an opening through which the animal to be captured can enter the front and rear surfaces. A casket body 1 in which 1a is formed, a pair of drop doors 2 and 2 that close the opening 1a by dropping from above each opening 1a of the casket body 1, and each drop door 2 above the opening 1a of the casket body 1 And a release mechanism 4 for releasing the holding state of the drop door 2 by the holding mechanism 3, and a bottom plate unit 5 set on the bottom side of the bag main body 1. Then, the bottom plate unit 5 is set in the recess C provided on the ground G, and the bag body 1 is placed on the surrounding ground G.

前記檻本体１は、直方体の各辺に鋼製枠材を配し、両側面、上面および底面に鋼棒を格子状に配して、これらの各部材を互いに溶接したものである。そして、図２および図３に示すように、その底部の長手方向中央には略矩形の開口１ｂが形成され、使用時にはこの開口１ｂが前記底板ユニット５に臨むようになっている。なお、底部の開口１ｂの前後には、檻本体１の幅方向に延びる補強板６が設けられている。 The saddle body 1 is formed by arranging a steel frame material on each side of a rectangular parallelepiped, and arranging steel bars in a lattice shape on both side surfaces, an upper surface and a bottom surface, and welding these members to each other. As shown in FIGS. 2 and 3, a substantially rectangular opening 1b is formed at the center in the longitudinal direction of the bottom, and the opening 1b faces the bottom plate unit 5 when used. A reinforcing plate 6 extending in the width direction of the bag main body 1 is provided before and after the opening 1b at the bottom.

図２乃至図４に示すように、前記底板ユニット５は、檻本体１の底部の開口１ｂよりわずかに小さい外形に形成された固定部としての矩形枠７と、矩形枠７内の中央部で檻本体１の長手方向に向けて水平に配され、矩形枠７に両端部を回動可能に支持された一対の回動軸８、８と、各回動軸８に１枚ずつ取り付けられる一対の矩形の底板９、９と、矩形枠７と各底板９との間に差し渡されて各底板９を水平に支持する支持ピン１０とからなる。なお、この実施形態では、各底板９をそれぞれ２本の支持ピン１０で支持しているが、支持ピン１０は各底板９に１本ずつとしてもよい。 As shown in FIGS. 2 to 4, the bottom plate unit 5 includes a rectangular frame 7 as a fixed portion formed in an outer shape slightly smaller than the opening 1 b at the bottom of the bag body 1, and a central portion in the rectangular frame 7. A pair of pivot shafts 8, 8 that are horizontally arranged in the longitudinal direction of the rod body 1 and are supported by the rectangular frame 7 so as to be pivotable at both ends, and a pair attached to each pivot shaft 8. It consists of rectangular bottom plates 9, 9 and support pins 10 that are inserted between the rectangular frame 7 and each bottom plate 9 to support each bottom plate 9 horizontally. In this embodiment, each bottom plate 9 is supported by two support pins 10, but one support pin 10 may be provided for each bottom plate 9.

ここで、各底板９は、檻本体１の底部の長手方向中央部分を半分ずつ形成するように配され、檻本体１の幅方向中央側の端部の下面を回動軸８に固定されて、水平方向を向いたときにその回動先端が矩形枠７の短辺の内壁と対向するようになっている。また、図４（ａ）に示すように、各底板９の回動先端の上面には上方に立ち上がる帯状部９ａが形成されており、この帯状部９ａとこれに対向する矩形枠７の短辺の上端部を貫通するように支持ピン１０が差し込まれることにより、各底板９が水平に支持されている。そして、各支持ピン１０はアルミニウム等の軟質の金属で形成されており、図４（ｂ）に示すように、底板９に所定値以上のモーメントが加わったときに、支持ピン１０が折れ曲がり、底板９が支持ピン１０から離れて回動軸７と一体に回動するようになっている。 Here, each bottom plate 9 is arranged so as to form half the longitudinal center portion of the bottom portion of the heel body 1, and the lower surface of the end portion on the center side in the width direction of the heel body 1 is fixed to the rotation shaft 8. When turned in the horizontal direction, the tip of the rotation faces the inner wall of the short side of the rectangular frame 7. Further, as shown in FIG. 4A, a band-like portion 9a that rises upward is formed on the upper surface of the rotating tip of each bottom plate 9, and this belt-like portion 9a and the short side of the rectangular frame 7 facing this band-like portion 9a. Each of the bottom plates 9 is supported horizontally by inserting the support pins 10 so as to penetrate the upper end portion of the bottom plate 9. Each support pin 10 is made of a soft metal such as aluminum. As shown in FIG. 4B, when a moment of a predetermined value or more is applied to the bottom plate 9, the support pin 10 bends and the bottom plate 9 is separated from the support pin 10 and rotates together with the rotation shaft 7.

図１および図２に示すように、前記各落下扉２は、四角形の各辺に鋼製枠材を配し、その内側に鋼棒を格子状に配して、これらの各部材を互いに溶接したもので、檻本体１の開口１ａの両側に立設されたガイド部材（図示省略）に案内されて昇降可能となっている。また、その四角形の下辺を形成する鋼製枠材には逆Ｕ字状の吊上部材１１が上向きに取り付けられ、この吊上部材１１が後述するように保持機構３による落下扉２の保持に用いられる。 As shown in FIGS. 1 and 2, each of the drop doors 2 has a steel frame material arranged on each side of a quadrangle, and steel rods arranged in a lattice shape on the inside thereof, and these members are welded to each other. Thus, it can be raised and lowered by being guided by guide members (not shown) standing on both sides of the opening 1a of the bag main body 1. Further, an inverted U-shaped lifting member 11 is attached upward to the steel frame material forming the lower side of the quadrangle, and the lifting member 11 is used to hold the drop door 2 by the holding mechanism 3 as will be described later. Used.

前記保持機構３は、檻本体１の上面の長手方向両端近傍に回動可能に取り付けられた一対の支持棒（扉支持部材）１２、１２と、檻本体１の上面の長手方向中央部に係止される係止具１３（図５参照）と、各支持棒１２と係止具１３とを連結する一対の連結紐１４、１４とを備えている。各支持棒１２は、動物捕獲可能なセット状態では、一端部に落下扉２の吊上部材１１が引っ掛けられ、他端側が若干高くなるように傾いた姿勢で、落下扉２を檻本体１の開口１ａの上方で保持している。 The holding mechanism 3 is engaged with a pair of support rods (door support members) 12 and 12 that are rotatably attached to both ends in the longitudinal direction of the upper surface of the basket body 1 and a longitudinal central portion of the upper surface of the basket body 1. The locking tool 13 (refer FIG. 5) to be stopped is provided, and a pair of connecting cords 14 and 14 that connect each support rod 12 and the locking tool 13 are provided. In the set state in which animals can be captured, each support bar 12 is in a posture in which the lifting member 11 of the drop door 2 is hooked at one end and the other end is inclined slightly higher so that the drop door 2 is attached to the main body 1. It is held above the opening 1a.

ここで、図５（ａ）に示すように、係止具１３は、Ｌ字状の棒部材であり、前記セット状態（係止状態）では、一端側の長尺部１３ａを水平に向け他端側の短尺部１３ｂを下向きにした姿勢で、その短尺部１３ｂに各連結紐１４を連結されている。このとき、各連結紐１４は、一端を支持棒１２に結合され、他端に設けられた環状の係止部１４ａを係止具１３の短尺部１３ｂに掛けられて、係止具１３を檻本体１の幅方向の一側へ引っ張る状態で張られている。また、係止具１３の短尺部１３ｂには、一端を檻本体１に結合された係止紐１５の他端に取り付けた連結環１６が掛けられ、係止紐１５が係止具１３を各連結紐１４と反対側に引っ張る状態で張られている。そして、その係止紐１５は、途中で係止具１３の長尺部１３ａに掛けられた解除環（解除片）１７に通されて、係止具１３を引っ張る角度を調整されており、これによって各連結紐１４と係止紐１５が係止具１３を引っ張る力がつり合い、各支持棒１２が図１に実線で示した姿勢で落下扉２を保持できるようになっている。 Here, as shown in FIG. 5 (a), the locking tool 13 is an L-shaped bar member, and in the set state (locked state), the long portion 13a on one end side is directed horizontally. Each connecting string 14 is connected to the short part 13b in a posture in which the short part 13b on the end side faces downward. At this time, one end of each connecting string 14 is coupled to the support rod 12, and an annular locking portion 14 a provided at the other end is hung on the short portion 13 b of the locking tool 13, so that the locking tool 13 is The main body 1 is stretched while being pulled to one side in the width direction. Further, a connecting ring 16 attached at one end to the other end of the locking cord 15 coupled to the bag main body 1 is hung on the short portion 13b of the locking device 13, and the locking cord 15 connects the locking device 13 to each other. It is stretched in a state of being pulled to the side opposite to the connecting string 14. Then, the locking string 15 is passed through a release ring (release piece) 17 hung on the long portion 13a of the locking tool 13 in the middle, and the angle for pulling the locking tool 13 is adjusted. As a result, the force with which each of the connecting strings 14 and the locking string 15 pulls the locking tool 13 is balanced, so that each support bar 12 can hold the drop door 2 in the posture shown by the solid line in FIG.

また、前記解除機構４は、上記のようにセット状態で係止具１３の長尺部１３ａに掛けられる解除環１７（図５（ａ）参照）と、一端が矩形枠７に固定され、他端が解除環１７に結合される解除紐１８（図２および図５（ａ）参照）とを備えている。 The release mechanism 4 includes a release ring 17 (see FIG. 5A) that is hung on the long portion 13a of the locking tool 13 in the set state as described above, one end fixed to the rectangular frame 7, and the like. A release string 18 (see FIGS. 2 and 5A) whose end is coupled to the release ring 17 is provided.

ここで、解除紐１８は、図２、図３および図４（ａ）に示すように、矩形枠７の一側の内壁から一対の底板９、９の下方を通過して矩形枠７の他側壁を貫通した後、檻本体１の下から外側へ出て他側面に沿って上り、檻本体１の上面の上方で解除環１７に結合されるように張られている。なお、この実施形態では、解除紐１８の一端を矩形枠７に固定しているが、檻本体１に固定するようにしてもよい。 Here, as shown in FIGS. 2, 3, and 4 (a), the release string 18 passes from the inner wall on one side of the rectangular frame 7 below the pair of bottom plates 9, 9 to the other of the rectangular frame 7. After penetrating the side wall, it extends from the bottom of the heel body 1 to the outside, rises along the other side surface, and is stretched so as to be coupled to the release ring 17 above the upper surface of the heel body 1. In this embodiment, one end of the release string 18 is fixed to the rectangular frame 7, but it may be fixed to the bag main body 1.

そして、図２および図４（ｂ）に示すように、底板９に所定値以上の下向きのモーメントが加わると、支持ピン１０が折れ曲がって底板９から抜け、底板９が回動軸８と一体に回動してその下方を通る解除紐１８を押し下げる。これと同時に、図５（ａ）に一点鎖線で示すように、解除環１７が引っ張られて係止具１３の長尺部１３ａから抜ける。すると、各連結紐１４と係止紐１５が係止具１３を引っ張る力のつり合いがくずれ、係止具１３の檻本体１への係止状態が解除される。これにより、図５（ｂ）に示すように係止具１３の短尺部１３ｂから各連結紐１４の係止部１４ａおよび連結環１６が外れて、図１に一点鎖線で示すように各支持棒１２が落下扉２の重量によって大きく回動し、各落下扉２が同時に落下するようになっている。 As shown in FIGS. 2 and 4 (b), when a downward moment of a predetermined value or more is applied to the bottom plate 9, the support pin 10 bends and comes out of the bottom plate 9, and the bottom plate 9 is integrated with the rotating shaft 8. The release string 18 that rotates and passes below is rotated. At the same time, the release ring 17 is pulled out of the elongated portion 13a of the locking tool 13 as shown by a one-dot chain line in FIG. Then, the balance of the force with which each connecting string 14 and the locking string 15 pulls the locking tool 13 is lost, and the locking state of the locking tool 13 to the heel body 1 is released. As a result, as shown in FIG. 5 (b), the locking portions 14a and the connecting rings 16 of the connecting cords 14 are detached from the short portions 13b of the locking tools 13, and the supporting rods are shown as shown by a one-dot chain line in FIG. 12 is greatly rotated by the weight of the drop door 2, and the drop doors 2 are dropped simultaneously.

この動物捕獲用檻は、上述したように、底板９上に動物が乗って底板９に所定値以上のモーメントが加わったときに、底板ユニット５の矩形枠７と底板９との間に差し渡された支持ピン１０が折れ曲がって底板９が回動することにより、解除機構４が作動して保持機構３による各落下扉２の保持状態が解除され、各落下扉２が同時に落下して檻本体１の前後面の開口１ａが閉じられるようにしたものである。 As described above, this animal catching cage is inserted between the rectangular frame 7 and the bottom plate 9 of the bottom plate unit 5 when an animal rides on the bottom plate 9 and a moment of a predetermined value or more is applied to the bottom plate 9. When the support pin 10 is bent and the bottom plate 9 is rotated, the release mechanism 4 is actuated to release the holding state of the drop doors 2 by the holding mechanism 3, and the drop doors 2 are dropped at the same time so The opening 1a on the front and rear surfaces of 1 is closed.

したがって、捕獲対象外の小動物が檻本体１に入って底板９上に乗っても、その動物の重量によって底板９に生じるモーメントが所定値未満であれば、支持ピン１０が折れ曲がることなく底板９を支持し続けるので、檻本体１の各開口１ａが閉じられることはなく、捕獲可能な状態が維持される。このため、捕獲対象外の小動物に対しても作動するおそれのある従来のものに比べて、保持機構３や解除機構４の再セットの頻度が少なく、檻本体１の各開口１ａが閉じられている期間が短縮されるので、捕獲対象である比較的大型の動物を効率よく捕獲することができる。 Therefore, even if a small animal that is not to be captured enters the cage body 1 and rides on the bottom plate 9, if the moment generated on the bottom plate 9 by the weight of the animal is less than a predetermined value, the support pin 10 is not bent and the bottom plate 9 is not bent. Since it keeps supporting, each opening 1a of the bag main body 1 is not closed, but the state which can be captured is maintained. For this reason, the holding mechanism 3 and the release mechanism 4 are reset less frequently than the conventional one that may operate even for small animals that are not captured, and each opening 1a of the cocoon body 1 is closed. Since the period of time is shortened, it is possible to efficiently capture a relatively large animal to be captured.
