Description
【０００１】
【発明の属する技術分野】
本発明は、内部に釣糸が通過可能な中通し竿と、このような中通し竿の先端に配置されるトップガイドに関する。
【０００２】
【従来の技術】
中通し竿においては、釣糸の繰り出し及び巻き取りの際に、竿体の内部に設けられた釣糸通路を釣糸が通過する。釣糸は竿体の先端から外部に延びている。このような中通し竿では、竿体の先端で釣糸の方向が変わるので、竿体先端の角部で釣糸が擦られて切れたり弱くなったりしやすい。
【０００３】
そこで、竿体先端に釣糸を保護するためのトップガイドが設けられる。トップガイドには、金属などからなる管体の内面に摩擦係数の小さなセラミックスなどからなる保護リングが装着されている。この保護リングにより釣糸が滑らかに案内され、釣糸が切れたり弱くなるのを防止することができる。
トップガイドの具体的技術が、実開平６−２４４６４号公報に示されている。この技術では、トップガイドの穂先側と後端側の２個所に釣糸と接触するセラミックリングを設け、そのうちの後端側のセラミックリングの内径をトップガイド本体の内径よりも小さくしてある。このように後端側のセラミックリング内径を小さくすることよって、釣糸の抵抗を少なくするとともに釣糸でトップガイドの内面が傷つかないようにしている。
【０００４】
【発明が解決しようとする課題】
前記従来のトップガイドでは、竿体先端に隣接してセラミックリングが配置されているので、釣糸が竿体先端に接触する心配は少ない。しかし、径が異なる複数のセラミックリングをトップガイドに並べて取り付けると、小さい径のセラミックリングの前後に釣糸に付着した水分や砂等の異物が溜まりやすい。このように異物が溜まると釣糸の抵抗が増加するため、掃除をして異物を取り除く必要がある。しかし、前記従来のトップガイドでは径が小さいセラミックリングがトップガイドの奥に位置しているので、仮にトップガイドを竿体に対して着脱自在に構成しても、２つのセラミックリングの間や内部に溜まった異物を除去しにくい。
【０００５】
本発明の課題は、中通し竿のトップガイドにおいて、釣糸の保護を良好に行えるとともに内部に異物が溜まっても簡単に除去できるようにすることにある。
【０００６】
【課題を解決するための手段】
発明１に係る中通し竿に取り付けられるトップガイドは、中通し竿の竿体先端に配置され内部を釣糸が通過するトップガイドであって、前記竿体の穂先側に配置され前記竿体の先端外周に嵌合固定される装着筒部に着脱自在に装着される第１筒部と、前記第１筒部の穂先側に配置され前記第１筒部に着脱自在に装着され内径が前記第１筒部より大きい第２筒部を備え、前記第１筒部の先端部は、前記竿体先端より突出し、かつ、第２筒部の内部に配置され、前記第１筒部先端部内径は、前記竿体先端部内径より小さい。
【０００７】
このトップガイドでは、釣糸が内部を通過すると第２筒部より径が小さい第１筒部の内周面に接触し第１筒部の内部やその前後に異物が溜まりやすい。この第１筒部及び第２筒部は竿体及び第２筒部に対してそれぞれ着脱自在であるため、異物が溜まれば第１筒部及び第２筒部を竿体及び第１筒部からそれぞれ離脱させる。これにより第１筒部の内部やその前後に溜まった異物を簡単に除去できる。しかも、第１筒部と第２筒部とで釣糸を案内できるので釣糸の保護を良好に行える。
【０００８】
さらに、発明１に係る中通し竿に取り付けられるトップガイドは、竿体は、先細り筒状の竿本体と、竿本体の先端の外周に嵌合固定される装着筒部とを有し、第１筒体は、装着筒部の穂先側に配置され装着筒部に着脱自在に装着されている。この場合には、トップガイドに竿体との着脱用の構成（装着筒部）をつくりこむ必要がないので、トップガイドの構成が簡素になる。
【００１０】
発明２に係る中通し竿のトップガイドは、発明１に記載のガイドにおいて、第１筒部及び第２筒部は装着筒部及び第１筒部にねじ嵌合によりそれぞれ着脱自在に装着されている。この場合には、着脱用の構成をねじ構造で実現することで、着脱用の構成が簡素化する。
【００１１】
発明３に係る中通し竿のトップガイドは、発明１又は２に記載のガイドにおいて、第１筒部の穂先側の内面に装着された環状の第１釣糸案内部をさらに備える。この場合には、第１筒部の穂先側に第１釣糸案内部を装着することで、釣糸の保護をより良好に行える。
発明４に係る中通し竿のトップガイドは、発明３に記載のガイドにおいて、第２筒部の穂先側の内面に装着された環状の第２釣糸案内部をさらに備える。この場合には、第１釣糸案内部に加えて第２筒部の穂先側に第２釣糸案内部を装着することで、釣糸の保護をより良好に行える。
【００１２】
発明５に係る中通し竿のトップガイドは、発明４に記載のガイドにおいて、第１釣糸案内部の内径は第２釣糸案内部の内径より小さい。この場合には、第１釣糸案内部の内径が小さいので、異物が第１釣糸案内部の前後により溜まりやすくなり、異物の除去を確実に行える。
発明６に係る中通し竿のトップガイドは、発明３から５のいずれかに記載のガイドにおいて、第１釣糸案内部の内径は竿体の内径より小さい。この場合には、第１釣糸案内部の内径が竿体の内径より小さいので、竿体の先端部で釣糸が竿体に接触しにくくなり、釣糸の保護をより良好に行える。
【００１３】
発明７に係る中通し竿のトップガイドは、発明４から６のいずれかに記載のガイドにおいて、各釣糸案内部は硬質セラミック製のリング部材からなっている。この場合には、表面が滑らかで摩擦係数が小さく耐久性に優れた硬質セラミック製のリング部材からなる釣糸案内部により釣糸が案内されるので、釣糸の保護をより良好に行えるとともに、釣糸案内部が損傷しにくくなり、トップガイドの耐久性も向上する。
【００１４】
発明８に係る中通し竿のトップガイドは、発明１から７のいずれかに記載のガイドにおいて、第２筒部の第１筒部より穂先側の周面には、内外周を貫通する異物排出孔が形成されている。この場合には、第１筒部より穂先側に溜まった異物の一部は異物排出孔から排出させることができるので、第１筒部より穂先側に異物が溜まりにくくなる。
【００１５】
発明９に係る中通し竿は、内部に釣糸が通過可能な竿であって、竿体と、トップガイドとを備えている。竿体は、釣糸が通過する釣糸通路を内部に有している。トップガイドは、竿体の先端に配置された請求項１から８のいずれかに記載のガイドである。この中通し竿では、釣糸が釣糸通路とトップガイドとを通過したときに第１筒部の径が小さいので異物が第１筒部に溜まりやすい。この第１筒部は着脱自在なため、発明１と同様に異物を簡単に除去でき、しかも釣糸の保護を良好に行える。
【００１６】
発明１０に係る中通し竿は、発明９に記載の竿において、竿体の釣糸通路の少なくとも一部には釣糸を案内する案内凸部が形成されている。この場合には、トップガイドの２つの筒部と案内凸部とで釣糸を案内するので、釣糸の案内及び保護を確実に行える。
【００１７】
【発明の実施の形態】
図１に示す本発明の一実施形態による中通し竿１０は、中通し竿１０を操作するためのグリップ部１２と、グリップ部１２の穂先側に連結された竿体１４と、竿体１４の先端に配置された筒状のトップガイド４０とを備えている。グリップ部１２の穂先側には、釣糸３０を巻回するリール２０が装着されている。竿体１４は筒状をなし内部に釣糸通路１５（図２）を有するとともに、竿元側に釣糸３０を内部に導入するための糸導入口１６を有する。竿体１４は、ガラス繊維、簡素繊維等の高強度繊維基材に樹脂を含浸させたプリプレグを先細り棒状のマンドレルに巻回し焼成して得られる先細り筒状の部材である。リール２０から引き出された釣糸３０は、糸導入口１６から竿体１４の内部に入り、トップガイド４０から外部に引き出される。
【００１８】
図２に示すように、トップガイド４０は、竿体１４の先端の外周に嵌合固定される装着筒部４１と、装着筒部４１の穂先側に配置された第１筒部４２と、第１筒部４２の穂先側に配置された第２筒部４３とを有している。これらの３つの筒部４１〜４３の外周面は滑らかに連続しており後端部（竿元側）にいくに従い小径となっている。
【００１９】
装着筒部４１は、たとえばステンレスやチタン合金等の耐食金属製の筒状部材であり、その先端部（穂先側）外周面には、竿体１４の外形に沿って第１雄ねじ部４１ａが形成されている。また、第１雄ねじ部４１ａから後端部にかけて外周面には、大径の末細りテーパ面４１ｂが形成されている。装着筒部４１は、接着などの適宜の固着手段により竿体１４に固定されている。しかし、着脱する必要があれば、竿体１４に対して着脱自在に嵌合されるようになっていてもよい。
【００２０】
第１筒部４２は、たとえばガラス繊維を混入した６６ナイロン等の弾性を有する合成樹脂製の筒状部材であり、装着筒部４１に着脱自在に装着されている。第１筒部４２の後端部内周面には第１雄ねじ部４１ａに螺合する第１雌ねじ部４２ａが形成されている。また、先端部は第１雌ねじ部４２ａより小径となっており、そこには、穂先側に突出した第１嵌入段部４２ｂが形成されている。また、第１雌ねじ部４２ａと第１嵌入段部４２ｂとの間には先細りのテーパ部４２ｃが形成されている。第１筒部４２の後端部外周面には第１筒部４２を回しやすくするためのローレット状溝部４２ｄが形成されており、先端部には第２雄ねじ部４２ｅが形成されている。この第２雄ねじ部４２ｅは、第１雌ねじ部４２ａに釣り竿の軸方向で重畳するように形成されている。
【００２１】
第２筒部４３は、たとえばステンレスやチタン合金等の耐食金属製の筒状部材であり、第１筒部４２に着脱自在に装着され内径が第１筒部４２より大きい。なお、ここでいう第１筒部４２及び第２筒部４３の内径とは、後述する第１釣糸案内部４５及び第２釣糸案内部４６の内径Ｄ1 及びＤ2 のことである。第２筒部４３の後端部内周面には第２雄ねじ部４２ｅに螺合する第２雌ねじ部４３ａが形成されている。また、先端部外周面は急激に先拡がりになっており、その先端部には第２嵌入段部４３ｂが形成されている。第２嵌入段部４３ｂの内径は第１嵌入段部４２ｂより大きい。第２雌ねじ部４３ａと第２嵌入段部４３ｂとの間において第１筒部４２より穂先側には、釣糸３０に付着した異物等を外部に排出するための４つの異物排出孔４３ｃが周方向に間隔を隔てて形成されている。異物排出孔４３ｃは、第２筒部４３の内外周を貫通して形成されている。
【００２２】
第１筒部４２の先端から内面側の第１嵌入段部４２ｂにかけて、後側の第１釣糸案内部４５が嵌め込まれている。第１釣糸案内部４５は、サーメットセラミックの成形体からなるリング部材である。第１釣糸案内部４５は、第１筒部４２の先端を覆っている。第１釣糸案内部４５の断面形状は、中心側に向けて滑らかに突出した湾曲形状をなしている。第１釣糸案内部４５の内径Ｄ1 は、竿体１４の内径ｄ0 よりも小さくなっている。
【００２３】
第２筒部４３の第２嵌入段部４３ｂには、前側の第２釣糸案内部４６が嵌め込まれている。第２釣糸案内部４６も第１釣糸案内部４５と同様の材料からなっている。第２釣糸案内部４６の断面形状も、中心側に向けて滑らかに突出した湾曲形状をなしている。第２釣糸案内部４６は第２筒部４３の先端を覆い、その先端外周が第２筒部４３の外周に一致している。第２釣糸案内部４６の内径Ｄ2 は、竿体１４の内径ｄ0 よりも大きくなっている。
【００２４】
このようなトップガイド４０を有する中通し竿１０では、リール２０からの釣糸３０は、内部の釣糸通路１５及びトップガイド４０の内部を通過してトップガイド４０の先端から導出される。そして、釣糸３０の繰り出し時や巻き取り時には、釣糸３０は釣糸通路１５や第１及び第２釣糸案内部４５，４６に接触する。ここで、第１釣糸案内部４５が最も小径であるので、釣糸３０に頻繁に接触しやすい。このため、糸繰り出し時には釣糸３０に付着した異物が第１釣糸案内部４５により扱かれて第１釣糸案内部４５の後側のテーパ部４２ｃに溜まりやすく、糸巻き取り時には釣糸３０に付着した異物が第１釣糸案内部４５の前側の第２筒部４３内に溜まりやすい。
【００２５】
このようにして第１釣糸案内部４５の前後に異物が溜まった場合には、図３に示すように、第１筒部４２及び第２筒部４３をそれぞれ取り外せばそれらの内部や竿体１４の先端部を簡単に掃除することができ、異物を容易に除去できる。しかも、第２筒部４３には異物を排出するための異物排出孔４３ｃが周面に設けられているので、異物が第２筒部４３内に溜まりにくい。
【００２６】
また、上記実施例では、２つの筒部４２，４３が着脱自在であるので、とくに、製造時や補修時に第１嵌入段部４２ｂに対して第１釣糸案内部４５を簡単に装着できる。
さらに、装着筒部４１及び第２筒部４３が金属製であり、その間の第１筒部４２が弾性を有する合成樹脂製であるので、互いにねじ結合しても金属と弾性を有する合成樹脂との結合によりねじの緩みが少なくなる。
【００２７】
また、装着筒部４１と第１筒部４２との締結部及び第２筒部と第２筒部との締結部が軸方向で重畳しているので、トップガイド４０全体の強度が強くなる。
〔他の実施形態〕
（ａ） 図４に示すように、竿体１４を製造するときにその先端に厚肉部１４ａを形成し、それにねじ加工して装着筒部４１を構成し、そこにトップガイド４０ａの第１筒部４２を着脱自在に装着してもよい。また、竿体１４自身の先端にねじ加工を直接行い、竿体１４にトップガイド４０ａの第１筒部４２を着脱自在に装着してもよい。
【００２８】
このトップガイド４０ａは、第１筒部４２と第２筒部４３とを有している。第１筒部４２は、前記実施形態と同様に、第１雌ねじ部４２ａと第１嵌入段部４２ｂとテーパ部４２ｃとローレット状溝部４２ｄと第２雄ねじ部４２ｅとを有している。また、ローレット状溝部４２ｄの後端部外周面は末細りテーパ面となっている。第２筒部４３の構成は前述した実施形態と同様である。
【００２９】
このような構成では、トップガイド４０ａにその着脱のための構成（装着筒部）が不要になるので、トップガイド４０ａの構成が簡素になる。
なお、図４に示す実施形態では、竿体１４の内面の釣糸通路１５に螺旋状に突出した釣糸案内凸部１５ａが形成されている。この釣糸案内凸部１５ａは釣糸通路１５の全体ではなく、少なくとも一部に設ければよい。釣糸案内凸部１５ａの断面形状は、中心側に向けて狭くなる概略台形状をなし、台形状の上辺角部が円弧状に丸められている。竿体１４の内部の釣糸通路１５を通過する釣糸３０は釣糸案内凸部１５ａに沿って移動する。この場合には、竿体１４の内径ｄ0 とは、突出した釣糸案内凸部１５ａの内径になる。
【００３０】
（ｂ）中通し竿１０の構造は、図示した実施例のほか、通常の中通し竿と同様の構造を適宜に組み合わせて構成することができる。リール２０やグリップ部１２、糸導入口１６などの構造も、通常の中通し竿と同様の構造が採用できる。
（ｃ）トップガイド４０の装着筒部４１、第１筒部４２及び第２筒部４３の材料は、前記実施例に限定されるものではなく、従来のトップガイドと同様の材料、具体的には金属、合成樹脂、木質材、セラミックなどの材料を用いることができる。
【００３１】
（ｄ）第１及び第２釣糸案内部４５、４６の材料は、前述したサーメットセラミックのように、摩擦係数が小さく耐久性に優れた材料が好ましい。サーメットセラミック以外のセラミックや金属、合成樹脂も使用できる。また、各釣糸案内部４５，４６をそれぞれの筒部４２，４３に一体で形成してもよい。
【００３２】
【発明の効果】
本発明に係るトップガイド及び中通し竿では、第１筒部は竿体及び第２筒部に対して着脱自在であるため、異物が溜まれば第１筒部及び第２筒部を竿体及び第１筒部からそれぞれ離脱させることで、第１筒部の内部やその前後に溜まった異物を簡単に除去できる。しかも、第１筒部と第２筒部とで釣糸を案内できるので釣糸の保護を良好に行える。

BACKGROUND OF THE INVENTION
The present invention relates to a penetrating rod through which a fishing line can pass and a top guide disposed at the tip of such penetrating rod.
[0002]
[Prior art]
In the threading rod, the fishing line passes through a fishing line passage provided in the rod body when the fishing line is fed and wound. The fishing line extends outward from the tip of the housing. In such a through rod, the direction of the fishing line changes at the tip of the rod, and the fishing line is easily rubbed and weakened at the corner of the rod tip.
[0003]
Therefore, a top guide for protecting the fishing line is provided at the end of the housing. The top guide is provided with a protective ring made of ceramics having a small friction coefficient on the inner surface of a tube made of metal or the like. The fishing line is smoothly guided by the protective ring, and the fishing line can be prevented from being cut or weakened.
A specific technique of the top guide is disclosed in Japanese Utility Model Laid-Open No. 6-24464. In this technique, ceramic rings that contact the fishing line are provided at two points on the tip side and the rear end side of the top guide, and the inner diameter of the ceramic ring on the rear end side is made smaller than the inner diameter of the top guide body. In this way, by reducing the inner diameter of the ceramic ring on the rear end side, the resistance of the fishing line is reduced and the inner surface of the top guide is not damaged by the fishing line.
[0004]
[Problems to be solved by the invention]
In the conventional top guide, since the ceramic ring is disposed adjacent to the front end of the housing, there is little concern that the fishing line will contact the front end of the housing. However, when a plurality of ceramic rings having different diameters are mounted side by side on the top guide, foreign matters such as water and sand attached to the fishing line are likely to collect before and after the small diameter ceramic rings. If foreign matter accumulates in this way, the resistance of the fishing line increases, so it is necessary to remove the foreign matter by cleaning. However, in the conventional top guide, the ceramic ring having a small diameter is located at the back of the top guide. Therefore, even if the top guide is configured to be detachable from the housing, it is provided between the two ceramic rings or inside. It is difficult to remove foreign matter accumulated on the surface.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to provide excellent protection of fishing line and allow easy removal even if foreign matter accumulates inside the top guide of the penetrating rod.
[0006]
[Means for Solving the Problems]
The top guide attached to the threading rod according to the first aspect of the invention is a top guide that is disposed at the tip of the rod of the threading rod and through which the fishing line passes, and is disposed on the tip side of the rod and disposed at the tip of the rod. A first tube portion that is detachably mounted on a mounting tube portion that is fitted and fixed to the outer periphery, and a first tube portion that is disposed on the tip side of the first tube portion and is detachably mounted on the first tube portion. A second cylinder portion larger than the cylinder portion is provided , a tip end portion of the first cylinder portion protrudes from the tip end of the housing, and is arranged inside the second cylinder portion, and an inner diameter of the tip end portion of the first cylinder portion is It is smaller than the inner diameter of the front end of the casing .
[0007]
In this top guide, when the fishing line passes through the inside, it comes into contact with the inner peripheral surface of the first cylinder part having a diameter smaller than that of the second cylinder part, and foreign matter tends to accumulate inside or around the first cylinder part. Since this 1st cylinder part and the 2nd cylinder part are each detachable with respect to a housing and a 2nd cylinder part, if a foreign material accumulates, a 1st cylinder part and a 2nd cylinder part will be a housing and a 1st cylinder part. Separate from each. As a result, the foreign matter accumulated in the first tube portion and in the front and back thereof can be easily removed. In addition, since the fishing line can be guided by the first cylinder part and the second cylinder part, the fishing line can be well protected.
[0008]
Further, in the top guide attached to the through collar according to the first aspect of the present invention, the casing has a tapered cylindrical casing main body and a mounting cylinder portion fitted and fixed to the outer periphery of the tip of the casing main body. The cylinder is disposed on the tip side of the mounting cylinder and is detachably mounted on the mounting cylinder. In this case, since it is not necessary to create a structure for attaching to and detaching from the housing (mounting cylinder part) in the top guide, the structure of the top guide is simplified.
[0010]
Invention through in according to the 2 pole of the top guide is in the guide according to the invention 1, the first tubular portion and a second tubular portion is detachably attached respectively by screws fitting into hollow mounting portion and a first cylindrical portion Yes. In this case, the detachable configuration is simplified by realizing the detachable configuration with a screw structure.
[0011]
The top guide of the threading rod according to a third aspect of the present invention is the guide according to the first or second aspect , further comprising an annular first fishing line guide portion mounted on the inner surface of the first tube portion on the tip side. In this case, the fishing line can be protected better by mounting the first fishing line guide part on the tip side of the first tube part.
The top guide of the threading rod according to a fourth aspect of the present invention is the guide according to the third aspect , further comprising an annular second fishing line guide portion mounted on the inner surface of the second tube portion on the tip side. In this case, it is possible to better protect the fishing line by mounting the second fishing line guide part on the tip side of the second tube part in addition to the first fishing line guide part.
[0012]
The top guide of the threading rod according to the invention 5 is the guide according to the invention 4 , wherein the inner diameter of the first fishing line guide portion is smaller than the inner diameter of the second fishing line guide portion. In this case, since the inner diameter of the first fishing line guide portion is small, foreign matters are likely to accumulate before and after the first fishing line guide portion, and the foreign matters can be reliably removed.
The top guide of the through rod according to the invention 6 is the guide according to any one of the inventions 3 to 5 , wherein the inner diameter of the first fishing line guide portion is smaller than the inner diameter of the housing. In this case, since the inner diameter of the first fishing line guide portion is smaller than the inner diameter of the rod body, it becomes difficult for the fishing line to contact the rod body at the tip portion of the rod body, and the fishing line can be protected better.
[0013]
The top guide of the threading rod according to a seventh aspect of the present invention is the guide according to any one of the fourth to sixth aspects, wherein each fishing line guide portion is made of a hard ceramic ring member. In this case, since the fishing line is guided by the fishing line guide part made of a hard ceramic ring member having a smooth surface, a small friction coefficient and excellent durability, the fishing line guide part can be better protected. Is less likely to be damaged, and the durability of the top guide is improved.
[0014]
The top guide of the penetrating rod according to the invention 8 is the guide according to any one of the inventions 1 to 7 , wherein the foreign matter passing through the inner and outer circumferences on the tip side of the second tube portion from the first tube portion is discharged. A hole is formed. In this case, since a part of the foreign matter accumulated on the tip side from the first tube portion can be discharged from the foreign matter discharge hole, the foreign matter is less likely to accumulate on the tip side than the first tube portion.
[0015]
The through rod according to the ninth aspect is a rod through which a fishing line can pass, and includes a rod body and a top guide. The rod has a fishing line passage through which the fishing line passes. Top guide is a guide according to any one of claims 1, which is located at the tip of the fishing rod body 8. In this through rod, when the fishing line passes through the fishing line passage and the top guide, the diameter of the first tube portion is small, so that foreign matter tends to accumulate in the first tube portion. Since this 1st cylinder part is detachable, a foreign material can be easily removed similarly to invention 1, and it can protect fishing line satisfactorily.
[0016]
The through rod according to the tenth aspect of the present invention is the rod according to the ninth aspect , wherein a guide convex portion for guiding the fishing line is formed on at least a part of the fishing line passage of the frame. In this case, since the fishing line is guided by the two cylindrical portions of the top guide and the guide convex portion, the fishing line can be reliably guided and protected.
[0017]

In the threading rod 10 having such a top guide 40, the fishing line 30 from the reel 20 passes through the inside fishing line passage 15 and the inside of the top guide 40 and is led out from the tip of the top guide 40. When the fishing line 30 is paid out or taken up, the fishing line 30 comes into contact with the fishing line passage 15 and the first and second fishing line guides 45 and 46. Here, since the 1st fishing line guide part 45 is the smallest diameter, it is easy to contact the fishing line 30 frequently. For this reason, the foreign matter attached to the fishing line 30 is handled by the first fishing line guide portion 45 when the line is unwound, and is easily accumulated in the tapered portion 42c on the rear side of the first fishing line guide portion 45. It tends to accumulate in the second tube portion 43 on the front side of the first fishing line guide portion 45.
[0025]
In this way, when foreign matter has accumulated in front of and behind the first fishing line guide portion 45, as shown in FIG. 3, if the first tube portion 42 and the second tube portion 43 are removed, the inside and the housing 14 are removed. It is possible to easily clean the tip portion of the metal and easily remove foreign matters. Moreover, since the foreign matter discharge hole 43c for discharging the foreign matter is provided in the peripheral surface of the second cylindrical portion 43, the foreign matter is unlikely to accumulate in the second cylindrical portion 43.
[0026]
Moreover, in the said Example, since the two cylinder parts 42 and 43 are detachable, especially the 1st fishing line guide part 45 can be easily mounted | worn with respect to the 1st insertion step part 42b at the time of manufacture or repair.
Furthermore, since the mounting cylinder part 41 and the second cylinder part 43 are made of metal and the first cylinder part 42 between them is made of a synthetic resin having elasticity, a synthetic resin having a metal and elasticity even when screwed together. The looseness of the screw is lessened by the coupling of.
[0027]
Further, since the fastening portion between the mounting tubular portion 41 and the first tubular portion 42 and the fastening portion between the second tubular portion and the second tubular portion are overlapped in the axial direction, the strength of the entire top guide 40 is increased.
