Description

本発明は、先端に釣り上げた魚を海面より掬い取るタモ網を取り付けてある玉の柄、及び、その玉の柄の一番竿に装着される口栓に関する。 The present invention relates to a ball handle on which a tamo net for scooping fish caught at the tip from the sea surface is attached, and a spigot attached to the first cage of the ball handle.

この種の玉の柄は、一番竿を含む複数本の竿を振出竿として構成したものであり、一番竿の先端を保護し竿内への異物の侵入を阻止すべく口栓を備えているが、この口栓を一番竿の先端にネジ止め固定する構成を採っていた（特許文献１参照）。 This type of ball handle is composed of a plurality of spears, including the first spear, as a swing spear, and is equipped with a spigot to protect the front end of the first spear and prevent foreign objects from entering the spear. However, a configuration has been adopted in which this spigot is screwed and fixed to the tip of the most heel (see Patent Document 1).

特開２００４−１２９５３２号公報（段落番号〔００１１〕、図１）JP 2004-129532 A (paragraph number [0011], FIG. 1)

上記したように、ネジ止め固定する構成では、タモ網を取り付けてない状態では、ネジが緩みを生ずると口栓が一番竿から外れることがある。したがって、外れを防止するために口栓を一番竿に接着固定することも行っていたが、玉の柄が振出式の竿体で構成されているので、一番竿を二番竿の竿尻開口から抜き出すことができず、玉の柄を水洗いする等のメインテナンス時に難儀することもあり、接着固定する方策は好ましいものではなかった。 As described above, in the configuration in which the screw is fixed, in the state where the tamo- net is not attached, if the screw is loosened, the plug may come off the most. Therefore, in order to prevent detachment, the spigot was also glued and fixed to the first collar, but the ball handle is composed of a swing-out chassis, so the first collar is the second collar. The method of adhering and fixing was not preferable because it could not be extracted from the butt opening and was difficult during maintenance such as washing the ball handle with water.

本発明の目的は、口栓の脱着を可能としながら、外れにくい口栓及びそのような口栓を備えた玉の柄を提供する点にある。 An object of the present invention is to provide a plug which is difficult to come off while allowing the plug to be attached and detached, and a ball handle having such a plug.

〔構成〕
請求項１に係る発明の特徴構成は、一番竿の先端外周面に竿軸線方向に沿って形成した外向き摩擦保持部と雄ネジ部に対して、前記外向き摩擦保持部に接触する内向き摩擦保持部と前記雄ネジ部のネジに螺合する雌ネジ部とを形成してある点にあり、その作用効果は次の通りである。〔Constitution〕
The characteristic configuration of the invention according to claim 1 is that the outer friction holding portion and the male screw portion formed on the outer peripheral surface of the front end of the most collar along the axial direction are in contact with the outer friction holding portion. The direction friction holding part and the female screw part screwed into the screw of the male screw part are formed, and the operation and effect are as follows.

〔作用〕
つまり、口栓と一番竿とに亘って摩擦保持部とネジ部とを形成することによって、摩擦保持部によって口栓が竿の周方向に回転することを阻止でき、これによって、口栓が緩むことを阻止できる。そして、口栓が軸線方向に移動しようとしてもネジ部によって阻止できる。 [Action]
That is, by forming the friction holding portion and the screw portion over the plug and the first hook, it is possible to prevent the plug from rotating in the circumferential direction of the hook by the friction holding portion. Can prevent loosening. Even if the plug is about to move in the axial direction, it can be blocked by the screw portion.

〔効果〕
以上のように、摩擦保持部とネジ部とを形成することによって、互いの協働作用により、口栓の緩みと抜出しとを阻止でき、かつ、口栓を取り外してのメインテナンス作業を容易に行い得ることができた。〔effect〕
As described above, by forming the friction holding portion and the screw portion, it is possible to prevent the plug from being loosened and pulled out by the cooperative action of each other, and to easily perform the maintenance work by removing the plug. I was able to get it.

請求項２に係る発明の特徴構成は、前記内向き摩擦保持部の前記軸線方向に沿った長さを、前記雌ネジ部の前記軸線方向に沿った長さよりも長くし、前記内向き摩擦保持部の内径を前記雌ネジ部のピッチ径よりも小径に形成してある点にあり、その作用効果は次の通りである。 According to a second aspect of the present invention, the length of the inward friction holding portion along the axial direction is longer than the length of the female screw portion along the axial direction, so that the inward friction holding portion is maintained. The inner diameter of the portion is formed to be smaller than the pitch diameter of the female screw portion, and the effects thereof are as follows.

〔作用効果〕
つまり、口栓を一番竿の先端に取り付ける際には、口栓の後端開口から一番竿に外嵌させていくが、軸線方向に沿った長さがながく、かつ、小径に形成されている内向き摩擦保持部に対して一番竿の外向き摩擦保持部が内嵌されていくので、摩擦保持部同士の嵌合によって口栓と一番竿との軸芯が一定に維持されて、ネジ部の螺合を容易に行え、口栓の取り付けを容易に行うことができる。 [Function and effect]
In other words, when attaching the plug to the tip of the most heel, it is externally fitted to the heel from the rear end opening of the plug, but the length along the axial direction is short and the diameter is small. Since the outermost friction holding part is fitted into the inner friction holding part, the shaft core between the plug and the first hook is kept constant by fitting the friction holding parts. Thus, the threaded portion can be easily screwed and the plug can be easily attached.

請求項３に係る発明の特徴構成は、前記雌ネジ部の前記軸線方向に沿った長さを、前記内向き摩擦保持部の前記軸線方向に沿った長さよりも長くし、前記雌ネジ部のピッチ径を前記内向き摩擦保持部の内径よりも小径に形成してある点にあり、その作用効果は次の通りである。 According to a third aspect of the present invention, the length of the female screw portion along the axial direction is longer than the length of the inward friction holding portion along the axial direction of the female screw portion. The pitch diameter is formed to be smaller than the inner diameter of the inward friction holding portion, and the effects thereof are as follows.

〔作用効果〕
つまり、口栓を一番竿の先端に取り付ける際には、口栓の後端開口から一番竿に外嵌させていくが、軸線方向に沿った長さが長く、かつ、小径に形成されている雌ネジ部に対して一番竿の雄ネジ部が内嵌されていくので、口栓と雄ネジ部とのネジ嵌合が進むにつれて摩擦保持部同士の嵌合が開始されるが、口栓と一番竿との軸芯が一定に維持された状態で、摩擦保持部同士の嵌合が進むので、嵌合を容易に行えるとともに、口栓の取り付けを容易に行うことができる。 [Function and effect]
In other words, when attaching the plug to the tip of the most heel, it is fitted on the heel from the rear end opening of the plug, but the length along the axial direction is long and the diameter is small. Since the innermost male screw portion is fitted into the female screw portion, the fitting between the friction holding portions starts as the screw fitting between the plug and the male screw portion proceeds. Since the friction holding portions are fitted with each other while the axial center of the plug and the first collar is maintained constant, the fitting can be easily performed and the plug can be easily attached.

請求項４に係る発明の特徴構成は、一番竿の先端外周面に竿軸線方向に沿って外向き摩擦保持部と雄ネジ部とを形成するとともに、一番竿の先端に装着される口栓の内周面に、一番竿の先端に口栓を外嵌装着した状態で、前記外向き摩擦保持部に接触する内向き摩擦保持部と前記雄ネジ部のネジに螺合する雌ネジ部とを形成し、前記外向き摩擦保持部と前記内向き摩擦保持部とを、先端側程小径となるテーパ面に形成してある点にあり、その作用効果は次の通りである。 The characteristic configuration of the invention according to claim 4 is that an outer friction holding portion and a male screw portion are formed on the outer peripheral surface of the front end of the first collar along the axial direction of the first collar, and a mouth mounted on the distal end of the first collar A female screw that is screwed into an inward friction holding portion that contacts the outward friction holding portion and a screw of the male screw portion in a state in which a mouth plug is externally fitted on the inner peripheral surface of the stopper. And the outward friction holding portion and the inward friction holding portion are formed on a tapered surface having a smaller diameter toward the distal end side. The operational effects are as follows.

〔作用効果〕
つまり、口栓を一番竿の先端に取り付ける際には、口栓の後端開口から一番竿に外嵌させていくが、雌ネジ部に対して一番竿の雄ネジ部が螺合されていく。一方、摩擦保持部同士は、テーパ面に形成されているので、ネジ部同士の螺合が進んでいく過程では摩擦保持部同士が接触することはない。
したがって、口栓をネジ込んでいく際は、摩擦保持部によって抵抗は発生しないので、容易にネジ込み操作が行える。
ネジ込みが完了すると、初めて、摩擦保持部同士が接触して摩擦保持力が発揮される。
このことによって、口栓の取り付け取り外しが容易に行えながら、摩擦保持部同士の摩擦保持力によって、口栓の緩み止め機能が発揮される。 [Function and effect]
In other words, when attaching the plug to the tip of the most heel, it is fitted to the heel most from the rear end opening of the plug, but the male screw part of the heel is screwed into the female screw part. It will be done. On the other hand, since the friction holding portions are formed on tapered surfaces, the friction holding portions do not come into contact with each other in the process of screwing between the screw portions.
Therefore, when screwing the plug, no resistance is generated by the friction holding portion, so that the screwing operation can be easily performed.
For the first time, when the screwing is completed, the friction holding portions come into contact with each other and the friction holding force is exhibited.
As a result, the stopper can be prevented from being loosened by the friction holding force between the friction holding portions, while the plug can be easily attached and detached.

請求項５に係る発明の特徴構成は、前記口栓の外周面に、元竿の竿先端を嵌合する外向き嵌合面を形成してある点にあり、その作用効果は次の通りである。 The characteristic configuration of the invention according to claim 5 resides in that an outward fitting surface for fitting the front end of the gutter is formed on the outer peripheral surface of the spigot. is there.

〔作用効果〕
つまり、一番竿の先端に取り付けた口栓に元竿を外嵌固定することができるので、元竿内に一番竿を収納した収縮状態にでき、口栓によって玉の柄を収縮状態に維持でき、口栓の有効利用が図れる。 [Function and effect]
In other words, the main fence can be externally fixed to the spigot attached to the tip of the first spear, so that it can be in a contracted state in which the first spear is stored in the main spear, and the handle of the ball is contracted by the spigot. It can be maintained and the plug can be used effectively.

〔第１実施形態〕
振出竿式の玉の柄Ａについて説明する。
振出竿式の玉の柄Ａは、図１に示すように、一番竿１と、二番竿２、三番竿３、元竿４とを備えて、構成されている。一番竿１には口栓５を装備し、元竿４の竿尻端には尻栓６が設けてある。
玉の柄Ａは、一番竿１、二番竿２、三番竿３を元竿４内に収納する収縮状態と一番竿１、二番竿２、三番竿３を元竿４より引き出した伸長状態とに切換可能に構成されている。 [First Embodiment]
An explanation will be given of the ball handle A of the swinging bowl type.
As shown in FIG. 1, the swinging-out type ball handle A includes a first basket 1, a second basket 2, a third basket 3, and a former basket 4. The most heel 1 is equipped with a spigot 5, and a butt plug 6 is provided at the butt end of the heel 4.
The handle A of the ball is in a contracted state in which the first basket 1, the second basket 2 and the third basket 3 are stored in the main basket 4 and the first basket 1, the second basket 2 and the third basket 3 from the main basket 4. It is configured to be switchable to the drawn-out extended state.

一番竿１等の各竿体は、炭素繊維等の強化繊維を引き揃え、その引き揃えた強化繊維群に、エポキシ等の熱硬化性樹脂を含浸させて形成したプリプレグを所定の形状に裁断し、その裁断したメインパターンをマンドレルに巻回し、巻回したものを焼成して、所定の寸法に切断して、形成される。 Each casing such as the first ridge 1 is made by aligning reinforced fibers such as carbon fibers, and cutting the prepreg formed by impregnating the aligned reinforcing fiber group with a thermosetting resin such as epoxy. Then, the cut main pattern is wound around a mandrel, and the wound main pattern is fired and cut into a predetermined dimension.

一番竿１の先端には、魚を掬い取るタモ網Ｂが取付られる。その取り付け構造を説明する。図１及び図２に示すように、タモ網Ｂは、網本体７と枠体８とからなり、枠体８に一番竿１への装着部８Ａが形成されている。装着部８Ａには雄ネジ軸８ａが突設されている。
一方、一番竿１の先端内には取付用スリーブ９が嵌め込み固定してあり、その取付用スリーブ９の内周面に雌ネジ部９ａが形成されている。
以上のようなネジ部構造によって、図２（ハ）に示すように、タモ網Ｂの雄ネジ軸８ａを取付用スリーブ９の雌ネジ部９ａに螺合させることによって、タモ網Ｂを玉の柄Ａに取り付けることができる。 A tamo net B that scoops up fish is attached to the tip of the first rod 1. The mounting structure will be described. As shown in FIGS. 1 and 2, the tamo net B includes a net body 7 and a frame body 8, and a mounting portion 8 A for the most heel 1 is formed on the frame body 8. A male screw shaft 8a projects from the mounting portion 8A.
On the other hand, a mounting sleeve 9 is fitted and fixed in the front end of the most collar 1, and a female screw portion 9 a is formed on the inner peripheral surface of the mounting sleeve 9.
With the above-described threaded portion structure, as shown in FIG. 2C, the male threaded shaft 8a of the tamo net B is screwed into the female threaded part 9a of the mounting sleeve 9, so that Can be attached to handle A.

口栓５と一番竿１との取り付け構造について説明する。図１及び図２に示すように、口栓５は、その外周面に、前端側から後端側に掛けて、大径摘まみ部５Ａと、中径元竿用嵌合部５Ｂと、小径逃げ部５Ｃとを形成して構成されており、かつ、その内周面に、前端側から後端側に掛けて、小径の内向き摩擦保持部５Ｄと、大径の雌ネジ部５Ｅとを形成して構成されている。 The attachment structure of the spigot 5 and the first hook 1 will be described. As shown in FIGS. 1 and 2, the plug 5 is hung on the outer peripheral surface from the front end side to the rear end side, with a large diameter knob 5A, a medium diameter main shaft fitting part 5B, and a small diameter. An escape portion 5C is formed, and a small-diameter inward friction holding portion 5D and a large-diameter female screw portion 5E are hung on the inner peripheral surface from the front end side to the rear end side. Formed and configured.

大径摘まみ部５Ａには、ローレット加工が施してあり、摘まみ易い構造になっている。また、中径元竿用嵌合部５Ｂには、竿の軸線方向に沿った溝５ａが周方向に複数個設けてあり、元竿４を内嵌合する際に、摩擦抵抗を軽減しながら、溝５ａを形成されていない平坦部分での密着性を良好なものにする構成としてある。このように、溝５ａの形成によって、寸法誤差等に起因して全周面を元竿４の内周面に接触させる難しさを緩和する構成となっている。
口栓５はゴム製のものであり、アクリロニトリルーブタジエンゴム（ＮＢＲ）でできている。但し、このゴムに相当する硬度を有するものであれば、合成樹脂を材料とすることもできる。 The large-diameter knob 5A is knurled so that it can be easily picked. In addition, the middle diameter main rod fitting portion 5B is provided with a plurality of circumferential grooves 5a along the axial direction of the rod, while reducing the frictional resistance when fitting the main rod 4 inside. In this configuration, the adhesiveness in a flat portion where the groove 5a is not formed is improved. As described above, the formation of the groove 5a reduces the difficulty of bringing the entire circumferential surface into contact with the inner circumferential surface of the main shaft 4 due to a dimensional error or the like.
The plug 5 is made of rubber and is made of acrylonitrile-butadiene rubber (NBR). However, a synthetic resin can be used as long as it has a hardness corresponding to this rubber.

一番竿１には、図２（イ）に示すように、竿先端から竿尻側に向けて、小径の外向き摩擦保持部１Ａと大径の雄ネジ部１Ｂとが形成してあり、図２（ロ）に示すように、口栓５を一番竿１に装着した状態で、外向き摩擦保持部１Ａが口栓５の内向き摩擦保持部５Ｄ内に嵌合圧接するとともに、雄ネジ部１Ｂが口栓５の雌ネジ部５Ｅに螺合して、装着状態を維持する構成となっている。 As shown in FIG. 2 (a), the first flange 1 is formed with a small-diameter outward friction holding portion 1A and a large-diameter male screw portion 1B from the tip of the heel toward the buttock side. As shown in FIG. 2 (b), the outer friction holding portion 1A is fitted and pressed into the inward friction holding portion 5D of the plug 5 while the plug 5 is attached to the most flange 1, and the male The threaded portion 1B is threadedly engaged with the female threaded portion 5E of the spout 5 to maintain the mounting state.

図２（ハ）に示すように、一番竿１にタモ網Ｂを取り付けた際には、タモ網Ｂの装着部８Ａの側面８ｂを、口栓５の前面５ｄに当接させている。口栓５は前記したようにゴム製でありその弾性変形性により軸線方向に圧縮される。これによって、口栓５はタモ網Ｂと一番竿１とに離間する方向の力を作用させるところから、タモ網Ｂ側のネジ軸８ａとスリーブ９との螺合状態を維持する機能を発揮することになる。 As shown in FIG. 2 (c), when the tamo net B is attached to the first cage 1, the side surface 8 b of the mounting portion 8 A of the tamo net B is brought into contact with the front surface 5 d of the spout 5. The plug 5 is made of rubber as described above, and is compressed in the axial direction by its elastic deformation. As a result, the plug 5 exerts the function of maintaining the screwed state between the screw shaft 8a and the sleeve 9 on the side of the tamo net B from the position where the force in the direction separating from the tamo net B and the first flange 1 acts. Will do.

玉の柄Ａは振出竿式のものであるので、各竿体を伸長させた使用状態から各竿体を短縮させた状態とに切り換えられるものであるが、第２図（ロ）に示すように収縮状態に設定すると、元竿４の竿先端開口が口栓５の中径元竿用嵌合部５Ｂに外嵌し、その収縮状態を維持するようになっている。 Since the ball handle A is of a swinging-out type, it can be switched from a use state in which each case is extended to a state in which each case is shortened, as shown in FIG. 2 (b). When set to the contracted state, the heel tip opening of the main rod 4 is externally fitted to the medium diameter main rod fitting portion 5B of the plug 5 so as to maintain the contracted state.

〔第２実施形態〕
ここでは、口栓５に形成される内向き摩擦保持部５Ｄと雌ネジ部５Ｅの形成位置を、入れ替えた状態で形成したものを示す。この入れ替えに対応して一番竿１における外向き摩擦保持部１Ａと雄ネジ部１Ｂとの形成位置を変更する構成について説明する。図３に示すように、口栓５の前端側に小径の雌ネジ部５Ｅを形成するとともに、後端側に大径の摩擦保持部５Ｄを形成し、軸線方向での長さを摩擦保持部５Ｄに比べて雌ネジ部５Ｅの長さを長くしてある。 [Second Embodiment]
Here, what formed in the state which replaced the formation position of the inward friction holding | maintenance part 5D and female thread part 5E which are formed in the stopper 5 is shown. The structure which changes the formation position of the outward friction holding | maintenance part 1A and the external thread part 1B in the most collar 1 corresponding to this replacement | exchange is demonstrated. As shown in FIG. 3, a small-diameter female screw portion 5E is formed on the front end side of the plug 5 and a large-diameter friction holding portion 5D is formed on the rear end side, and the length in the axial direction is set to the friction holding portion. The length of the female screw portion 5E is longer than that of 5D.

一方、一番竿１においては、図３に示すように、竿先端から竿尻側に向けて、小径の雄ネジ部１Ｂと大径の外向き摩擦保持部１Ａとが形成してあり、図示はしていないが、尻栓５を一番竿１に装着した状態で、外向き摩擦保持部１Ａが口栓５の内向き摩擦保持部５Ｄ内に嵌合圧接するとともに、雄ネジ部１Ｂが尻栓５の雌ネジ部５Ｅに螺合して、装着状態を維持する構成となっている。 On the other hand, as shown in FIG. 3, the first collar 1 is formed with a small-diameter male screw portion 1B and a large-diameter outward friction holding portion 1A from the distal end of the heel toward the buttock side. Although not attached, the outer friction holding portion 1A is fitted and pressed into the inward friction holding portion 5D of the spigot 5 with the buttocks plug 5 attached to the most flange 1, and the male screw portion 1B is It is configured to be screwed into the female thread portion 5E of the bottom plug 5 to maintain the mounting state.

このような構成によって、口栓５を一番竿１の先端に取り付ける際には、口栓５の後端開口５ｂから一番竿１に外嵌させていくが、軸線方向に沿った長さが長く、かつ、小径に形成されている雌ネジ部５Ｅに対して一番竿１の雄ネジ部１Ａが内嵌されていくので、口栓５と雄ネジ部１Ａとのネジ嵌合が進むにつれて摩擦保持部１Ａ，５Ｄ同士の嵌合が開始されるが、口栓５と一番竿１との軸芯が一定に維持された状態で、摩擦保持部同士の嵌合が進むので、嵌合を容易に行えるとともに、口栓の取り付けを容易に行うことができる。 With such a configuration, when the plug 5 is attached to the tip of the most heel 1, it is externally fitted to the ridge 1 from the rear end opening 5 b of the plug 5, but the length along the axial direction is Since the male screw portion 1A of the first flange 1 is fitted into the female screw portion 5E that is long and has a small diameter, the screw fitting between the plug 5 and the male screw portion 1A proceeds. As the fitting between the friction holding portions 1A and 5D starts, the fitting between the friction holding portions proceeds in a state where the shaft core of the plug 5 and the first flange 1 is kept constant. In addition to facilitating the fitting, the plug can be easily attached.

上記構成においては、口栓５に形成された内向き摩擦保持部５Ｄの軸線方向長さは、雌ネジ部５Ｅの軸線方向長さよりは短くなっているが大径に形成されているので、摩擦保持力を高く採ることが出来て、ネジ部での緩み止め効果を高くできる。 In the above configuration, the axial length of the inward friction holding portion 5D formed on the plug 5 is shorter than the axial length of the female screw portion 5E, but is formed to have a large diameter. The holding force can be taken high, and the effect of preventing loosening at the screw portion can be enhanced.

〔第３実施形態〕
ここでは、口栓５に形成される内向き摩擦保持部５Ｄと雌ネジ部５Ｅの形成位置を、第１実施形態のものと同一にしながら、内向き摩擦保持部５Ｄの形状を変更したものについて説明する。この変更に対応して一番竿１における外向き摩擦保持部１Ａの形状を変更する構成について説明する。図４に示すように、口栓５の前端側に内向き摩擦保持部５Ｄを形成するとともに後端側に雌ネジ部５Ｅを形成し、軸線方向での長さを摩擦保持部５Ｄに比べて雌ネジ部５Ｅの長さを短くしてある。 [Third Embodiment]
Here, the shape of the inward friction holding portion 5D is changed while the inward friction holding portion 5D and the female screw portion 5E formed on the plug 5 are formed in the same positions as those in the first embodiment. explain. The structure which changes the shape of the outward friction holding | maintenance part 1A in the most collar 1 corresponding to this change is demonstrated. As shown in FIG. 4, an inward friction holding portion 5D is formed on the front end side of the plug 5 and a female screw portion 5E is formed on the rear end side, so that the length in the axial direction is longer than that of the friction holding portion 5D. The length of the female screw portion 5E is shortened.

一方、一番竿１においては、図３に示すように、竿先端から竿尻側に向けて、外向き摩擦保持部１Ａと雄ネジ部１Ｂとが形成してあり、図示はしていないが、尻栓５を一番竿１に装着した状態で、外向き摩擦保持部１Ａが口栓５の内向き摩擦保持部５Ｄ内に嵌合圧接するとともに、雄ネジ部１Ｂが尻栓５の雌ネジ部５Ｅに螺合して、装着状態を維持する構成となっている。 On the other hand, as shown in FIG. 3, the first flange 1 has an outward friction holding portion 1 A and a male screw portion 1 B that are formed from the tip end of the heel toward the buttock side. The outer friction holding portion 1A is fitted and pressed into the inward friction holding portion 5D of the spigot 5 with the buttocks plug 5 attached to the most flange 1, and the male screw portion 1B is the female of the bottom plug 5 The screw portion 5E is screwed to maintain the mounting state.

口栓５に形成された内向き摩擦保持部５Ｄは、前端開口５ｃ側が小径で後端側大径に形成されており、摩擦保持部５Ｄがテーパ面となっている。このことに対応して、一番竿１に形成されている外向き摩擦保持部１Ａも竿先側が小径で竿尻側程大径となるテーパ面に形成されて、口栓５を一番竿１に取り付けた状態で摩擦保持部１Ａ、５Ｄ同士が接触するように構成してある。 The inward friction holding portion 5D formed on the plug 5 has a small diameter on the front end opening 5c side and a large diameter on the rear end side, and the friction holding portion 5D has a tapered surface. Corresponding to this, the outward friction holding portion 1A formed on the most heel 1 is also formed on a tapered surface having a small diameter on the heel side and a larger diameter on the buttock side. 1, the friction holding portions 1 A and 5 D are in contact with each other.

以上のような構成によって、口栓５を一番１竿の先端に取り付ける際には、口栓５の後端開口５ｂから一番竿１に外嵌させていくが、雌ネジ部５Ｅに対して一番竿１の雄ネジ部１Ａが螺合されていく。一方、摩擦保持部１Ａ、５Ｄ同士は、テーパ面に形成されているので、ネジ部１Ａ、５Ｅ同士の螺合が進んでいく過程では摩擦保持部１Ａ、５Ｄ同士が接触することはない。
したがって、口栓５をネジ込んでいく際は、摩擦保持部１Ａ、５Ｄによって抵抗は発生しないので、容易にネジ込み操作が行える。
ネジ込みが完了すると、初めて、摩擦保持部１Ａ、５Ｄ同士が接触して摩擦保持力が発揮される。
このことによって、口栓５の取り付け取り外しが容易に行えながら、摩擦保持部１Ａ、５Ｄ同士の摩擦保持力によって、口栓５の緩み止め機能が発揮される。 With the configuration as described above, when the plug 5 is attached to the tip of the first hook, the plug 5 is externally fitted to the hook 1 from the rear end opening 5b of the plug 5. Then, the male screw portion 1A of the first rod 1 is screwed together. On the other hand, since the friction holding portions 1A and 5D are formed on tapered surfaces, the friction holding portions 1A and 5D do not come into contact with each other in the process of screwing the screw portions 1A and 5E.
Therefore, when screwing the plug 5, no resistance is generated by the friction holding portions 1 A and 5 D, so that the screwing operation can be easily performed.
When the screwing is completed, the friction holding portions 1A and 5D are brought into contact with each other for the first time and the friction holding force is exhibited.
As a result, while the plug 5 can be easily attached and removed, the function of preventing the loosening of the plug 5 is exhibited by the friction holding force between the friction holding portions 1A and 5D.
