JP 2004-105125 A

本発明者は、特に、鮎の友釣りに適した竿を提供したいと考えている。鮎は、自分の生活圏である縄張りに他の鮎が侵入したとき、自分の餌場を守るためこれを猛然と追い払う。この習性を利用したのが鮎の友釣りである。鮎の友釣りでは、釣り糸に、おとり鮎を取り付け、おとり鮎に釣針を取り付けた仕掛けを用いる。そして、おとり鮎をポイントで泳がせ、おとり鮎を追い払いにきた野鮎をおとり鮎に取り付けた釣針に掛けて釣る。   The inventor of the present invention particularly wants to provide a kite suitable for kite fishing. When other sharks invade the territory that is their sphere of life, they are driven away to protect their feeding area. This habit is used for fishing for carp. In the fishing of a kite, a device is used in which a fishing rod is attached to a fishing line and a fishing hook is attached to the fishing rod. Then, let the decoy rod swim at the point, and hook the wild boar that came to drive off the decoy rod on the hook attached to the decoy rod.

かかる鮎の友釣りに用いられる釣竿には、釣り人がおとり鮎を操る操作性が良いことが求められる。すなわち、おとり鮎を操る際は、釣り人は竿元側で釣竿を操作するが、鮎竿は８ｍ〜１０ｍ程度の長い竿であり、竿元側の微妙な動きによって竿先が大きく動いてしまう。この際、釣り人の意に反して釣糸にテンションが掛かり、おとり鮎が引っ張られると上手くおとり鮎を操作できない。
また、鮎の友釣りでは、針に掛かった野鮎を取り込む際に、釣竿を引き上げ、水中から鮎を引き抜き、竿の弾性反力によって鮎を釣り人の方へ飛ばし、飛んできた鮎を網（タモ）で受ける技法がよく用いられる。かかる技法には釣竿が適度な弾性反力を奏することが必要である。 A fishing rod used for such fishing for a rod is required to have good operability for the angler to manipulate the decoy rod. That is, when maneuvering the decoy rod, the angler operates the fishing rod on the rod side, but the rod is a long rod of about 8m to 10m, and the rod tip moves greatly due to the delicate movement on the rod side. . At this time, if the fishing line is tensioned against the will of the angler and the decoy rod is pulled, the decoy rod cannot be operated successfully.
In addition, when fishing a rod attached to a needle, the fishing rod is lifted, the rod is pulled out from the water, the rod is moved toward the angler by the elastic reaction force of the rod, and the flying rod is netted ( The technique received in Tamo) is often used. Such a technique requires that the fishing rod exert an appropriate elastic reaction force.

特開２００４−１０５１２５号公報には、『穂先竿がソリッド体を接続したタイプの鮎竿に係るものである。曲げ剛性は、穂持竿の先端部Ｃを基準１と表現すれば、穂先竿の先端部Ａは０．００５〜０．０１であり、これは、従来の鮎竿の穂持竿のＣ部を同じ１とした場合の、一般的な従来竿の穂先竿先端部Ａの曲げ剛性の１／１０〜１／５程度であり、相当に柔らかい構成となっている。このため、釣りにおいて竿保持部が揺れても、穂先竿の結着部に至る穂先竿の曲げ剛性が小さい（柔らかい）ため、囮鮎に及ぶ釣糸の引張力の影響を低減できる（竿先が大きく振れることが防止される）。また、この穂先竿の長さは鮎竿の全長の１０％程度以下であるため、穂持竿から元竿までの各竿管の長さや曲げ剛性値を従来のものと同様に設定すれば、竿全体の操作性にはほとんど影響がなく、従来通りの操作性が確保できる。』と記載されている。
しかし、同公報では、穂先竿の先端部をＡ、ソリッド体の最大径部をＢ、穂持竿先端部をＣとした場合、各部の曲げ剛性比率Ａ：Ｂ：Ｃが、１：（３〜１８）：（１００〜２００）であると記載されているが、かかる比率のみでは、穂先部分がどの程度柔らかいかは分からない。 Japanese Patent Application Laid-Open No. 2004-105125 states that “a tip hook is related to a type of hook in which a solid body is connected. The bending rigidity is expressed as 0.001 to 0.01 when the tip C of the hot pot is expressed as the standard 1, and this is the C part of the conventional pot. 1 is about 1/10 to 1/5 of the bending rigidity of the tip A of a conventional tip of a conventional scissors, and the structure is considerably soft. For this reason, even if the rod holding part swings during fishing, the bending stiffness of the tip rod reaching the binding portion of the tip rod is small (soft), so the influence of the tensile force of the fishing line on the rod can be reduced (the tip is It is prevented from shaking greatly.) In addition, since the length of this spike is about 10% or less of the total length of the heel, if you set the length and bending rigidity value of each tub tube from the heel to the heel, There is almost no effect on the operability of the entire bag, and the operability as before can be secured. Is described.
However, in this publication, if the tip end of the tip is A, the maximum diameter part of the solid body is B, and the tip end of the head is C, the bending rigidity ratio A: B: C of each part is 1: (3 -18): Although described as (100 to 200), it is not known how soft the tip portion is only with such a ratio.

さらに、上述した特開２００４−１０５１２５号公報の請求項３には、『Ａ，Ｂ，Ｃ部の曲げ剛性が、夫々、４００〜８００ｋｇ・ｍｍ２（３９２０〜７８４０Ｎ・ｍｍ２）、１２００〜１４４００ｋｇ・ｍｍ２（１１７６０〜１４１１２０Ｎ・ｍｍ２）、４００００〜１６００００ｋｇ・ｍｍ２（３９２０００〜１５６８０００Ｎ・ｍｍ２）の範囲内から曲げ剛性比率の範囲内にあるように選択される』ことが記載されている。しかし、同公報の請求項３に記載されている曲げ剛性および曲げ剛性比率を有する鮎竿は、本発明者の知見では、十分に操作性が良い鮎竿とは言えない。
そこで、本発明者は、かかる鮎の友釣りに適した鮎竿を提供したいと考え、いままでにない穂先竿を考えた。 Further, in claim 3 of the above-mentioned Japanese Patent Application Laid-Open No. 2004-105125, “the bending rigidity of the parts A, B and C is 400 to 800 kg · mm 2 (3920 to 7840 N · mm 2 ) and 1200 to 14400 kg, respectively.・ Selected to be within the range of the bending rigidity ratio from the range of mm 2 (11760 to 141120 N · mm 2 ), 40000 to 160000 kg · mm 2 (392000 to 1568000 N · mm 2 ) ” . However, the kite having the bending stiffness and the flexural stiffness ratio described in claim 3 of the publication is not a kit with sufficiently good operability according to the knowledge of the present inventor.
Therefore, the present inventor wanted to provide a kite suitable for fishing for such a kite, and thought of a new tip kite.

本発明の穂先竿は、先端が中実竿体で構成された穂先竿であって、中実竿体は縦弾性率が１００〜２００（ｋN/mm２）の繊維強化樹脂で構成され、中実竿体は、竿先に釣糸を結び付けるトップ部を備え、トップ部を含む竿先から３ｃｍ〜５ｃｍの任意の位置までの穂先部分の曲げ剛性Ｘ１が１（ｋN・ｍｍ２）≦Ｘ１≦３（ｋN・ｍｍ２）である。
この穂先竿によれば、トップ部を含む竿先から３ｃｍ〜５ｃｍの任意の位置までの穂先部分が極めて柔らかく、竿元側の微妙な動きによって竿先が動いても、これに対して、当該穂先部分が曲がる。このため、例えば、鮎の友釣りにおいてはおとり鮎の操作への影響が小さい。また、トップ部を含む竿先から３ｃｍ〜５ｃｍまでの穂先部分が柔らかいので、魚を取り込む際には、釣竿を引き上げる操作によって竿元側を相当量動かす。この際、穂先の柔らかい部分が限定的であるから、魚を取り込む際の大きな操作では、釣糸に適度なテンションを掛けることができる。 The ear tip of the present invention is a tip tip composed of a solid rod, and the solid rod is composed of a fiber reinforced resin having a longitudinal elastic modulus of 100 to 200 (kN / mm 2 ). The actual rod body has a top portion that ties a fishing line to the tip of the rod, and the bending rigidity X1 of the tip portion from the tip including the top portion to an arbitrary position of 3 cm to 5 cm is 1 (kN · mm 2 ) ≦ X1 ≦ 3. (KN · mm 2 ).
According to the tip, the tip part from the tip including the top part to an arbitrary position of 3 cm to 5 cm is extremely soft, and even if the tip moves due to a delicate movement on the tip side, The tip is bent. For this reason, for example, in the fishing of a kite, the influence on the operation of the decoy kite is small. Further, since the tip portion from 3 cm to 5 cm from the tip including the top portion is soft, when the fish is taken in, the base side is moved by a considerable amount by the operation of pulling up the fishing rod. At this time, since the soft portion of the tip is limited, an appropriate tension can be applied to the fishing line in a large operation when taking in the fish.

以下、本発明の一実施形態に係る穂先竿を図面に基づいて説明する。   Hereinafter, a spikelet according to an embodiment of the present invention will be described with reference to the drawings.

この釣竿は、複数の竿体を継ぎ足して一本の釣竿として機能させている。複数の竿体のうち、最も穂先側に継ぎ足される竿体は穂先竿と呼ばれている。
穂先竿１０は、図１に示すように、先端が中実竿体２１で構成されている。中実竿体２１は、縦弾性率が１００〜２００（ｋN/mm２）の繊維強化樹脂で構成されている。
この実施形態では、中実竿体２１は、引張強さが２４ＭＰａで比重が１．８の炭素繊維を用い、炭素繊維６６％（重量パーセント）、エポキシ樹脂３４％（重量パーセント）の割合で炭素繊維にエポキシ樹脂を含浸させ、弾性率が135（ｋN/mm２）の繊維強化樹脂で構成している。
この中実竿体２１は、竿先に釣糸３１を結び付けるトップ部３２を備えている。この実施形態では、当該トップ部３２には、釣糸３１を結び付ける部位が回転可能に構成された回転トップと呼ばれる部材が取り付けられている。
この中実竿体２１は、トップ部３２を含む竿先から３ｃｍ〜５ｃｍまでの穂先部分１１の曲げ剛性Ｘ１が１（ｋN・ｍｍ２）≦Ｘ１≦３（ｋN・ｍｍ２）である。 The fishing rod functions as a single fishing rod by adding a plurality of rods. Of the plurality of rods, the rod that is added to the most tip side is called the tip rod.
As shown in FIG. 1, the tip rod 10 has a solid rod body 21 at the tip. The solid casing 21 is made of a fiber reinforced resin having a longitudinal elastic modulus of 100 to 200 (kN / mm 2 ).
In this embodiment, the solid casing 21 is made of carbon fiber having a tensile strength of 24 MPa and a specific gravity of 1.8, and is composed of carbon fiber 66% (weight percent) and epoxy resin 34% (weight percent). The fiber is impregnated with an epoxy resin and is composed of a fiber reinforced resin having an elastic modulus of 135 (kN / mm 2 ).
The solid rod body 21 includes a top portion 32 that ties a fishing line 31 to the tip of the rod. In this embodiment, a member called a rotary top is attached to the top portion 32 so that a portion to which the fishing line 31 is connected is rotatable.
In this solid rod body 21, the bending rigidity X1 of the tip portion 11 from 3 cm to 5 cm from the tip including the top portion 32 is 1 (kN · mm 2 ) ≦ X1 ≦ 3 (kN · mm 2 ).

この実施形態では、縦弾性率が１００〜２００（ｋN/mm２）の繊維強化樹脂で構成されている。トップ部３２を含む竿先から３ｃｍ〜５ｃｍの任意の位置までの穂先部分１１の曲げ剛性Ｘ１が１（ｋN・ｍｍ２）≦Ｘ１≦３（ｋN・ｍｍ２）である。
中実竿体２１の剛性Ｘは、弾性率をＥとし、竿体の外径をＤとすると、
Ｘ＝Ｅ×π×Ｄ４・・・式（１）
で表される。 In this embodiment, it is comprised with the fiber reinforced resin whose longitudinal elastic modulus is 100-200 (kN / mm < 2 >). The bending rigidity X1 of the tip portion 11 from the tip including the top portion 32 to an arbitrary position of 3 cm to 5 cm is 1 (kN · mm 2 ) ≦ X1 ≦ 3 (kN · mm 2 ).
The rigidity X of the solid casing 21 is that the elastic modulus is E and the outer diameter of the casing is D.
X = E × π × D 4 (1)
It is represented by

この穂先竿１０は、トップ部３２を含む竿先から３ｃｍ〜５ｃｍの任意の位置までの穂先部分１１の曲げ剛性Ｘ１が１（ｋN・ｍｍ２）≦Ｘ１≦３（ｋN・ｍｍ２）と、極めて柔らかい。このため、この穂先竿１０を鮎釣用の釣竿の穂先竿として用いれば、トップ部を含む竿先から３ｃｍ〜５ｃｍまでの穂先部分１１が極めて柔らかく、竿元側の微妙な動きによって竿先が動いても、これに対して、当該穂先部分１１が曲がるので、おとり鮎の操作への影響が小さい。
また、魚を取り込む際には、釣竿を引き上げる操作によって竿元側が相当量動かす。この際、この穂先竿１０は、図２に示すように、極めて柔らかい穂先部分１１が限定的であるから、魚を取り込む際の大きな操作では、釣糸３１に適度なテンションを掛けることができる。 In the tip 10, the bending rigidity X1 of the tip 11 from the tip including the top portion 32 to an arbitrary position of 3 cm to 5 cm is 1 (kN · mm 2 ) ≦ X1 ≦ 3 (kN · mm 2 ), Extremely soft. For this reason, if this tip rod 10 is used as a tip rod of a fishing rod for rod fishing, the tip portion 11 from 3 cm to 5 cm from the tip including the top portion is extremely soft, and the tip of the tip is caused by subtle movement on the tip side. Even if it moves, since the tip part 11 bends, the influence on the operation of the decoy rice cake is small.
Further, when the fish is taken in, the rod side moves by a considerable amount by the operation of lifting the fishing rod. At this time, as shown in FIG. 2, the tip rod 10 has a very soft tip portion 11, so that an appropriate tension can be applied to the fishing line 31 in a large operation when taking in the fish.

さらに、この実施形態では、中実竿体２１は竿先から竿元に向けて徐々に径が太くなるテーパ外形を有している。そして、トップ部３２を含む竿先から１０ｃｍ〜２５ｃｍの間の任意の位置において、当該任意の位置よりも竿先側の５ｃｍのテーパ率Ｙ１と、当該任意の位置よりも竿元側の５ｃｍのテーパ率Ｙ２が、Ｙ１＞２×Ｙ２となるように、テーパ率を変化させた曲がり点１２を設けている。
この穂先竿１０は、竿先から１５ｃｍの位置よりも竿先側の５ｃｍでは先端側へ向けて１ｍｍ当り、外径が０．０４〜０．１０ｍｍ小さくなるようにテーパを形成している。竿先から１５ｃｍの位置よりも竿元側の５ｃｍでは、先端側へ向けて１ｍｍ当り、外径が０．０１〜０．０２ｍｍ小さくなるようにテーパを形成している。このように、竿先から１５ｃｍの位置よりも竿先側の５ｃｍのテーパ率Ｙ１と、当該竿先から１５ｃｍの位置よりも竿元側の５ｃｍのテーパ率Ｙ２が、Ｙ１＞２×Ｙ２となるように、テーパ率を変化させた曲がり点１２を設けている。 Furthermore, in this embodiment, the solid casing 21 has a tapered outer shape whose diameter gradually increases from the tip of the hook toward the base of the hook. And, in an arbitrary position between 10 cm and 25 cm from the tip including the top portion 32, a taper ratio Y1 of 5 cm on the tip side relative to the arbitrary position, and 5 cm on the base side from the arbitrary position. The bending point 12 where the taper rate is changed is provided so that the taper rate Y2 satisfies Y1> 2 × Y2.
The tip 10 is tapered so that the outer diameter is smaller by 0.04 to 0.10 mm per 1 mm toward the tip at 5 cm on the tip side than the position 15 cm from the tip. The taper is formed so that the outer diameter is smaller by 0.01 to 0.02 mm per 1 mm toward the tip side at 5 cm on the heel side than the position 15 cm from the heel tip. Thus, the taper rate Y1 of 5 cm closer to the tip than the position of 15 cm from the tip and the taper rate Y2 of 5 cm closer to the foot than the position of 15 cm from the tip become Y1> 2 × Y2. As described above, the bending point 12 having a changed taper rate is provided.

式（１）によれば、中実竿体２１の剛性は、外径の４乗に比例しており、外径が細くなると剛性が著しく減少する。この実施形態では、鮎釣用穂先竿１０は、曲がり点よりも竿先側の５ｃｍのテーパ率が、曲がり点１２よりも竿元側の５ｃｍのテーパ率よりも２倍以上大きいので、曲がり点１２を境にして、竿元側に比べて竿先側が柔らかい。
この穂先竿１０は、上述したように、トップ部３２を含む竿先から３ｃｍ〜５ｃｍの穂先部分１１の曲げ剛性Ｘ１が１〜３（ｋN・ｍｍ２）であり、極めて柔らかい。このため、おとり鮎を操作する際、当該穂先部分１１が極めて柔らかいので、竿元の微妙な動きに対して釣糸に大きなテンションがかからないように当該穂先部分１１が曲がる。このため、竿元が微妙に動いた場合に、釣り人の意に反しておとり鮎が動かされない。 According to equation (1), the rigidity of the solid casing 21 is proportional to the fourth power of the outer diameter, and the rigidity is significantly reduced as the outer diameter becomes thinner. In this embodiment, the tip 10 for fishing rod has a taper rate of 5 cm closer to the tip than the bending point, and is more than twice as large as the taper rate of 5 cm closer to the foot than the bending point 12. The tip side is softer than the base side at 12 borders.
As described above, the tip of the tip 10 has a bending rigidity X1 of the tip 11 of 3 to 5 cm from the tip including the top portion 32 is 1 to 3 (kN · mm 2 ) and is extremely soft. For this reason, when operating the decoy rod, the tip portion 11 is very soft, so that the tip portion 11 bends so that a large tension is not applied to the fishing line against the delicate movement of the tip. For this reason, when the rod moves slightly, the rod is not moved against the angler's will.

また、この実施形態では、トップ部３２を含む竿先から１０ｃｍ〜２５ｃｍの間の任意の位置（この実施形態では、竿先から１５ｃｍの位置）に設定された曲がり点１２よりも竿先側の５ｃｍのテーパ率が、曲がり点１２よりも竿元側の５ｃｍのテーパ率よりも２倍以上大きい。すなわち、当該曲がり点１２よりも竿先側は、竿元側に比べて明らかに柔らかい。この穂先竿１０は、当該曲がり点１２よりも竿先側が適度に柔らかいので、当該曲がり点１２よりも竿先側の弾性反力により、おとり鮎を操作する際に適度なテンションを釣糸に生じさせることができる。これによりおとり鮎を操作する際に釣糸３１に生じさせるテンションの調整が容易になる。   Further, in this embodiment, the tip side is more than the bending point 12 set at an arbitrary position between 10 cm and 25 cm from the tip including the top portion 32 (in this embodiment, a position 15 cm from the tip). The taper ratio of 5 cm is twice or more larger than the taper ratio of 5 cm on the heel side from the bending point 12. That is, the tip side of the bending point 12 is clearly softer than the base side. Since the tip of the tip 10 is moderately softer than the bending point 12, the elastic reaction force on the tip side of the bending point 12 causes an appropriate tension to be generated in the fishing line when the decoy rod is operated. be able to. This facilitates adjustment of the tension generated in the fishing line 31 when operating the decoy rod.

さらに、鮎の友釣りでは、針に掛かった野鮎を取り込む際に、釣竿１０を大きく引き上げ、水中から鮎を抜き、水中から鮎を引き抜いたときの勢いによって、水面の上を釣り人の方へ飛ばし、飛んできた鮎を網で受ける技法がよく用いられる。
この穂先竿１０は、魚を取り込む際の大きな操作では、極めて柔らかい部位が、トップ部３２を含む竿先から３ｃｍ〜５ｃｍと限定的であり、かつ、上述したように、トップ部３２を含む竿先から１０ｃｍ〜２５ｃｍの間の任意の位置（この実施形態では、竿先から１５ｃｍの位置）において、曲がり点１２が設けられている。当該曲がり点１２よりも竿元側には適度な剛性を確保することができ、かかる竿元側の剛性によって、鮎釣用穂先竿１０に適度な剛性および弾性反力を作用させることができる。従って、この穂先竿１０を鮎釣用の釣竿の穂先竿として用いた場合には、特に、このような取り込み作業においても、上述した曲がり点１２よりも竿元側の弾性反力によって、鮎を勢いよく水中から引き抜くことができる。 Furthermore, in the fishing of a kite, when taking a samurai hung on a needle, the fishing rod 10 is lifted greatly, the rod is pulled out from the water, and the momentum when the rod is pulled out from the water makes the fisherman above the surface of the water. The technique of flying and catching flying kites with a net is often used.
The tip 10 has a very soft portion limited to 3 cm to 5 cm from the tip including the top portion 32 in a large operation when taking in the fish, and as described above, the tip including the top portion 32. A bending point 12 is provided at an arbitrary position between 10 cm and 25 cm from the tip (in this embodiment, a position 15 cm from the tip). Appropriate rigidity can be secured on the heel side of the bend point 12, and appropriate rigidity and elastic reaction force can be applied to the rod fishing tip 10 by the rigidity of the heel side. Therefore, when this tip rod 10 is used as a tip rod of a fishing rod for rod fishing, especially in such a taking-in operation, the rod is caused by the elastic reaction force on the heel side from the above-described bending point 12. It can be pulled out of the water.

このように、この穂先竿１０は、トップ部３２を含む竿先から１０ｃｍ〜２５ｃｍの間の任意の位置（この実施形態では、トップ部３２を含む竿先から１５ｃｍ）に曲がり点１２を設けている。例えば、鮎の友釣りでは、曲がり点１２を設ける位置が竿先側に寄っていると、それだけ、おとり鮎を操作する際の遊びが小さくなる。すなわち、釣り人により繊細な操作が求められる。反対に、曲がり点１２を設ける位置が竿元側に寄っていると、それだけ、おとり鮎を操作する際の遊びが大きくなる。   In this manner, the tip 10 is provided with the bending point 12 at an arbitrary position between 10 cm and 25 cm from the tip including the top portion 32 (in this embodiment, 15 cm from the tip including the top portion 32). Yes. For example, in the fishing of a shark, if the position where the bending point 12 is provided is closer to the tip of the heel, the play when operating the decoy rod is reduced accordingly. That is, a delicate operation is required by the angler. On the contrary, when the position where the bending point 12 is provided is closer to the heel side, the play when operating the decoy bowl becomes larger.

また、曲がり点１２を設ける位置が、トップ部３２を含む竿先から２５ｃｍよりも竿元側にあると、竿先側の柔らかい部分が長くなり過ぎ、針に掛かった野鮎を取り込む際に、釣竿を大きく引き上げ、水中から鮎を抜き、水中から鮎を引き抜いたときの勢いによって、水面の上を釣り人の方へ飛ばし難くなる。
このような点を考慮すると、曲がり点１２を設ける位置は、トップ部３２を含む竿先から１０ｃｍ〜２５ｃｍの間の任意の位置に曲がり点１２を設けるのがよい。
このように、本発明者の知見では、曲がり点１２は、トップ部３２を含む竿先から１０ｃｍ〜２５ｃｍの間の任意の位置（この実施形態では、トップ部３２を含む竿先から１５ｃｍ）に設けるのがよい。 In addition, when the position where the bending point 12 is provided is on the heel side more than 25 cm from the heel including the top portion 32, the soft part on the heel side becomes too long, and when taking the barb on the needle, The fishing rod is lifted greatly, the rod is pulled out of the water, and the momentum when the rod is pulled out of the water makes it difficult to fly to the angler.
In consideration of such points, the bending point 12 is preferably provided at an arbitrary position between 10 cm and 25 cm from the tip including the top portion 32.
Thus, according to the inventor's knowledge, the bending point 12 is at an arbitrary position between 10 cm and 25 cm from the tip including the top portion 32 (in this embodiment, 15 cm from the tip including the top portion 32). It is good to provide.

また、この実施形態では、穂先竿１０は、上述した中実竿体２１の竿元側には中空竿体２２が継ぎ合わされている。これにより、穂先竿１０全体を中実竿体２１にする場合に比べて、軽量にすることができる。   Moreover, in this embodiment, the hollow rod 22 is spliced to the tip side of the solid rod 21 mentioned above. Thereby, it can be reduced in weight compared with the case where the whole head rod 10 is made into the solid rod body 21.

なお、中空竿体２２の剛性Ｘ２は、弾性率をＥとし、中空竿体２２の外径をＤ２とし、竿体の内径をＤ１とすると、
Ｘ＝Ｅ×π×（Ｄ２４−Ｄ１４）・・・式（２）
で表される。
この穂先竿１０は、上述した中実竿体２１の竿元側には中空竿体２２が継ぎ合わされている。この実施形態では、中空竿体２２の先端に中実竿体２１の竿元側の端部２１ａを差し入れ、繊維強化樹脂で外径を一体的に接合している。
かかる中空竿体２２は、所要の剛性を確保しつつ、鮎釣用穂先竿全体を中実竿体で構成する場合に比べて、穂先竿１０を軽くできる。例えば、８ｍ〜１０ｍ程度の長さを有する鮎釣用の釣竿の穂先竿として好適である。上述した鮎釣用穂先竿１０は、竿元側に複数本の竿体が継ぎ足されて、一本の竿となる。
かかる鮎釣用の釣竿は、上述した穂先竿１０が穂先竿に用いられているので、鮎の友釣りにおいて、おとり鮎の操作性が良く、また、鮎を取り込む際の操作も容易である。 Note that the rigidity X2 of the hollow housing 22 is such that the elastic modulus is E, the outer diameter of the hollow housing 22 is D2, and the inner diameter of the housing is D1.
X = E × π × (D2 4 −D1 4 ) (2)
It is represented by
In the tip rod 10, the hollow rod body 22 is joined to the base side of the solid rod member 21 described above. In this embodiment, the end 21a on the flange side of the solid casing 21 is inserted into the tip of the hollow casing 22, and the outer diameter is integrally joined with fiber reinforced resin.
The hollow rod body 22 can reduce the tip rod 10 as compared with the case where the entire rod rod for fishing rod is constituted by a solid rod body while ensuring the required rigidity. For example, it is suitable as a tip rod of a fishing rod for fishing rods having a length of about 8 m to 10 m. The above-described fishing rod tip 10 has a plurality of rods added to the rod side to form a single rod.
In the fishing rod for fishing rods, since the above-mentioned tip rod 10 is used as the tip rod, the operability of the decoy rod is good in the fishing of the rod, and the operation when taking the rod is easy.

以上、本発明の一実施形態に係る鮎釣用穂先竿および鮎釣用竿を説明したが、本発明に係る鮎釣用穂先竿および鮎釣用竿は上述した実施形態に限定されない。
例えば、トップ部３２は回転トップとよばれる部材を取り付けた形態を例示したが、トップ部３２は釣糸３１を結び付ける部位であり、これに限らない。例えば、従来、リリアンで作成した締結具を取り付けたトップ部３２でもよい。 As described above, the rod fishing rod and the rod fishing rod according to one embodiment of the present invention have been described. However, the rod fishing rod and the rod fishing rod according to the present invention are not limited to the above-described embodiments.
For example, although the top part 32 illustrated the form which attached the member called a rotation top, the top part 32 is a site | part which connects the fishing line 31, and is not restricted to this. For example, the top part 32 which attached the fastener conventionally produced with Lilian may be sufficient.

また、本発明の穂先竿の構造は、鮎釣用竿以外の釣竿にも適用できる。この場合、当該釣竿は、先端が中実竿体で構成されており、中実竿体は、縦弾性率が１００〜２００（ｋN/mm２）の繊維強化樹脂で構成され、竿先から３ｃｍ〜５ｃｍの任意の位置までの穂先部分の曲げ剛性Ｘ１が１（ｋN・ｍｍ２）≦Ｘ１≦３（ｋN・ｍｍ２）であるとよい。
かかる釣竿によれば、中実竿体は、縦弾性率が１００〜２００（ｋN/mm２）の繊維強化樹脂で構成され、竿先から３ｃｍ〜５ｃｍの任意の位置までの穂先部分の曲げ剛性Ｘ１が１（ｋN・ｍｍ２）≦Ｘ１≦３（ｋN・ｍｍ２）であるので、竿先から３ｃｍ〜５ｃｍの穂先部分の曲げ剛性Ｘ１が１〜３（ｋN・ｍｍ２）であり、極めて柔らかい。このため、当該穂先部分が極めて柔らかいので、竿元の微妙な動きに対して釣糸に大きなテンションがかからないように当該穂先部分が曲がる。このため、竿元が微妙に動いた場合に、釣り人の意に反して仕掛けや疑似餌が動くのを小さく押さえることができる。 Further, the structure of the tip rod of the present invention can also be applied to a fishing rod other than a rod for fishing rods. In this case, the fishing rod has a tip made of a solid rod, and the solid rod is made of a fiber reinforced resin having a longitudinal elastic modulus of 100 to 200 (kN / mm 2 ), 3 cm from the tip of the rod. The bending rigidity X1 of the tip portion to an arbitrary position of ˜5 cm is preferably 1 (kN · mm 2 ) ≦ X1 ≦ 3 (kN · mm 2 ).
According to such a fishing rod, the solid rod body is composed of a fiber reinforced resin having a longitudinal elastic modulus of 100 to 200 (kN / mm 2 ), and the bending rigidity of the tip portion from the tip of the rod to an arbitrary position of 3 cm to 5 cm. Since X1 is 1 (kN · mm 2 ) ≦ X1 ≦ 3 (kN · mm 2 ), the bending rigidity X1 of the tip portion from 3 cm to 5 cm from the tip is 1 to 3 (kN · mm 2 ), soft. For this reason, since the tip portion is extremely soft, the tip portion is bent so that a large tension is not applied to the fishing line against the delicate movement of the base. For this reason, when the base moves slightly, it is possible to suppress the movement of the device and the pseudo bait against the angler's will.

また、中実竿体は竿先から竿元に向けて徐々に径が太くなるテーパ外形を有し、竿先から１０ｃｍ〜２５ｃｍの間の任意の位置において、当該任意の位置よりも竿先側の５ｃｍのテーパ率Ｙ１と、当該任意の位置よりも竿元側の５ｃｍのテーパ率Ｙ２が、Ｙ１＞２×Ｙ２となるように、テーパ率を変化させた曲がり点を設けてもよい。
この場合、当該曲がり点よりも竿先側は、竿元側に比べて明らかに柔らかい。この釣竿は、当該曲がり点よりも竿先側が適度に柔らかいので、仕掛けや疑似餌を操作する際に釣糸に作用させるテンションの調整が容易になる。 Further, the solid rod body has a tapered outer shape in which the diameter gradually increases from the tip of the tip toward the tip of the tip, and at any position between 10 cm and 25 cm from the tip of the tip, the tip side is more than the arbitrary position. A bending point with a changed taper ratio may be provided so that the taper ratio Y1 of 5 cm and the taper ratio Y2 of 5 cm closer to the base than the arbitrary position satisfy Y1> 2 × Y2.
In this case, the tip side is clearly softer than the base side than the bending point. Since this fishing rod has a moderately soft tip side relative to the bending point, it is easy to adjust the tension applied to the fishing line when operating the device or the pseudo bait.
