Description

本発明は、竿管外周に筒状部品を接着接合した釣竿に関する。筒状部品としては、リール装着部品としての筒状部品やグリップ用の筒状部品がある。   The present invention relates to a fishing rod in which a cylindrical part is bonded and joined to the outer periphery of a rod tube. Examples of the cylindrical part include a cylindrical part as a reel mounting part and a cylindrical part for grip.

釣竿にリールを装着するために、従来からシート状のリールシートや筒状の部品を竿管の所定領域に接着接合し、これらの部品にリールの足を装着固定することが行われている。この内、筒状部品を接着接合するに際しては、筒状部品内面と竿管表面との間に接着剤層用の適宜な隙間を形成する必要があるため、筒状部品内面に凸条等の複数の突起を設けることが考えられ、更には、筒状部品は合成樹脂材の射出成形で成形するため、後の型抜きを考えて長手方向に延伸させた複数の凸条を形成することが行われている。そうして成形された筒状部品の例が下記特許文献１の図にリールシート本体１として現れている。
実開平４−１２８６１号公報 In order to mount a reel on a fishing rod, conventionally, a sheet-like reel sheet or a cylindrical part is adhesively bonded to a predetermined region of a rod tube, and a reel foot is attached and fixed to these parts. Among these, when adhesively joining the cylindrical parts, it is necessary to form an appropriate gap for the adhesive layer between the inner surface of the cylindrical part and the pipe surface. It is conceivable to provide a plurality of protrusions. Furthermore, since the cylindrical part is formed by injection molding of a synthetic resin material, it is possible to form a plurality of ridges that are elongated in the longitudinal direction in consideration of later die cutting. Has been done. An example of the cylindrical part thus formed appears as a reel sheet main body 1 in the drawing of Patent Document 1 below.
Japanese Utility Model Publication 4-12861

然しながら、こうした凸条を設けた筒状部品を竿管と接着させる際に、筒状部品の外表面側から接着剤を圧入して竿管表面と筒状部品の内面との間の隙間に注入充填させる場合は、筒状部品内面の凸条の存在によって円周方向に流れ難く、不十分な充填状態の隙間が残って接着接合が不十分になる問題があった。また、射出成形による筒状部品は場所により肉厚も大きく変化する等が影響して、一般にその内面は真円には形成されておらず、例えば楕円状等に歪んでいることが多い。従って、予め竿管表面に接着剤を塗布しておき、竿管の長手方向に沿って筒状部品を押し込んで互いに接着接合させる場合も、竿管表面と筒状部品内面との隙間が円周方向において不均一になり、接着不十分な状態になりやすい。
依って解決しようとする課題は、竿管外周に筒状部品を十分に接着接合させた釣竿を提供することである。 However, when a cylindrical part provided with such ridges is bonded to the soot tube, an adhesive is injected from the outer surface side of the tubular part and injected into the gap between the soot pipe surface and the inner surface of the tubular part. In the case of filling, there is a problem that it is difficult to flow in the circumferential direction due to the presence of protrusions on the inner surface of the cylindrical part, and an insufficiently filled gap remains, resulting in insufficient adhesive bonding. In addition, the cylindrical part produced by injection molding is influenced by the fact that the wall thickness varies greatly depending on the location. Generally, the inner surface thereof is not formed into a perfect circle, and is often distorted into an elliptical shape, for example. Therefore, even when an adhesive is applied to the surface of the tubule in advance and the cylindrical parts are pushed in along the longitudinal direction of the tubule and bonded to each other, the gap between the surface of the tubule and the inner surface of the cylindrical part is circumferential. It becomes uneven in the direction and tends to be in a state of insufficient adhesion.
Therefore, the problem to be solved is to provide a fishing rod in which a cylindrical part is sufficiently bonded to the outer periphery of the rod tube.

第１の発明では、竿管の外周に筒状部品を接着接合させた釣竿であって、前記筒状部品の接着接合されている接着領域の竿管表面には、竿管の長手方向に対して交差する方向の凸条が該長手方向に複数配設されており、前記接着領域の長さ範囲に亘って竿管表面には前記凸条が配設されていない長手方向領域が存在していることを特徴とする釣竿を提供する。   In the first aspect of the present invention, there is provided a fishing rod in which a cylindrical part is adhesively bonded to the outer periphery of the rod tube, and the rod surface of the bonding area where the cylindrical component is bonded and bonded to the longitudinal direction of the rod tube A plurality of ridges in the crossing direction are arranged in the longitudinal direction, and there is a longitudinal region where the ridges are not arranged on the surface of the soot tube over the length range of the adhesive region. A fishing rod is provided.

第２の発明では、竿管の外周に筒状部品を接着接合させた釣竿であって、前記筒状部品にはその径方向に貫通して内側に接着剤を注入できる注入孔を有し、該筒状部品の接着接合されている接着領域の竿管表面には、竿管の長手方向に対して交差する方向の凸条が該長手方向に複数配設されており、前記注入孔を真下に見下ろす平面視において、竿管表面には、前記注入孔の位置を含み、前記接着領域の長さ範囲に亘って凸条が配設されていない長手方向領域が存在していることを特徴とする釣竿を提供する。   In the second invention, a fishing rod in which a cylindrical part is adhesively bonded to the outer periphery of the rod tube, the cylindrical part has an injection hole through which the adhesive can be injected in the radial direction, A plurality of ridges extending in the longitudinal direction are arranged on the surface of the soot tube in the adhesive region where the tubular parts are adhesively joined, and the longitudinal direction of the soot tube is arranged directly below the injection hole. In a plan view looking down, the surface of the soot tube has a longitudinal region that includes the position of the injection hole and is not provided with projections over the length range of the adhesive region. Provide fishing rods to do.

第３の発明では、第１又は第２の発明の各凸条は、前記長手方向領域の側の凸条端部から見た延伸方向が前記注入孔から遠ざかる方向であるように構成する。   In 3rd invention, each protruding item | line of 1st or 2nd invention is comprised so that the extending | stretching direction seen from the protruding item | line edge part by the side of the said longitudinal direction area may be a direction away from the said injection hole.

第４の発明では、第１〜第３の発明の前記長手方向領域の円周方向の両側に凸条が複数ずつ配設されており、各側の凸条は、前記注入孔から遠ざかるほど間隔が狭くなっているように構成する。   In the fourth invention, a plurality of ridges are disposed on both sides in the circumferential direction of the longitudinal region of the first to third inventions, and the ridges on each side are spaced apart from the injection hole. Is configured to be narrow.

第５の発明では、第１〜第４の発明の前記長手方向領域の円周方向の両側に凸条が複数ずつ配設されており、各側の凸条に挟まれた該長手方向領域の幅は、前記注入孔から遠ざかるほど狭くなっているように構成する。   In the fifth invention, a plurality of ridges are disposed on both sides in the circumferential direction of the longitudinal region of the first to fourth inventions, and the longitudinal region sandwiched between the ridges on each side. The width is configured to become narrower as the distance from the injection hole increases.

第１の発明では、竿管外周との接着接合に際して、竿管の所定位置において被さっている筒状部品の周面に注入孔を予め設けておき、そこから筒状部品の内部に接着剤を注入させる場合、注入孔付近では接着剤が四方に広がるが、該注入孔から竿管長手方向に離れると、接着剤は竿管長手方向に沿って流れるが、殆ど円周方向には流れない。これでは、筒状部品が覆っている竿管表面全体に接着剤を注入させることはできず、筒状部品の接着接合が不十分となる。この竿管長手方向に沿って流れる接着剤を円周方向にも流れるように案内するために、竿管長手方向に対して交差する方向の凸条を設けている。ここでは、これら凸条の延伸方向は竿管長手方向に対して傾斜する方向のみではなくて直交する方向でもよい。また、凸条によって竿管長手方向の流路が塞がれては、接着剤が竿管長手方向に流れなくなるため、その流路確保のためには、竿管表面には凸条の配設されていない長手方向領域を設けている必要がある。   In the first aspect of the present invention, an adhesive hole is provided in advance in the peripheral surface of the cylindrical part that is covered at a predetermined position of the vertical pipe, and an adhesive is then applied to the inside of the cylindrical part from the outer periphery of the vertical pipe. In the case of injecting, the adhesive spreads in all directions near the injection hole, but when leaving the injection hole in the longitudinal direction of the tubule, the adhesive flows along the longitudinal direction of the tubule, but hardly flows in the circumferential direction. In this case, the adhesive cannot be injected over the entire surface of the tubule covered by the cylindrical component, and the adhesive bonding of the cylindrical component becomes insufficient. In order to guide the adhesive flowing along the longitudinal direction of the tubule so as to also flow in the circumferential direction, a ridge in a direction intersecting the longitudinal direction of the tubule is provided. Here, the extending direction of these ridges may be not only a direction inclined with respect to the longitudinal direction of the tubule but also a direction orthogonal thereto. In addition, if the flow path in the longitudinal direction of the tubule is blocked by the ridges, the adhesive will not flow in the longitudinal direction of the tubule. It is necessary to provide a longitudinal region that is not.

また、複数の凸条を設けている竿管外周面に予め接着剤を塗布し、後から筒状部品を押し込んで接着接合させる場合も、押し込む筒状部品の内面と竿管表面との隙間は既述のような理由で、円周方向において必ずしも均一ではなく、不均一になる。従って、一般に筒状部品を押し込んでいる際中に、該筒状部品の内部に接着剤の不均一な充填状態が生じるが、筒状部品の内面と竿管表面との隙間の円周方向不均一の内で、相対的に小さい隙間領域の接着剤が筒状部品の動きに引かれて竿管長手方向に沿った流れが生じるが、この竿管長手方向の流れを凸条によって円周方向に案内でき、これにより接着剤を相対的に大きな隙間の方に補充でき、円周方向における接着剤の充填率のムラを防止でき、それだけ筒状部品の接着接合強度が向上する。   In addition, even when an adhesive is applied in advance to the outer peripheral surface of the soot tube provided with a plurality of ridges, and the tubular component is pushed in and bonded afterwards, the gap between the inner surface of the pushed-in tubular component and the soot tube surface is For the reasons already described, the circumferential direction is not necessarily uniform, and becomes non-uniform. Therefore, in general, while the cylindrical part is being pushed in, a non-uniform filling state of the adhesive is generated inside the cylindrical part, but the circumferential direction of the gap between the inner surface of the cylindrical part and the surface of the soot tube is not satisfactory. Within the uniform, the adhesive in the relatively small gap area is pulled by the movement of the cylindrical part, and a flow along the longitudinal direction of the duct occurs. Thus, the adhesive can be replenished in a relatively large gap, unevenness in the filling rate of the adhesive in the circumferential direction can be prevented, and the adhesive joint strength of the cylindrical part is improved accordingly.

第１の発明では、接着剤を注入孔を介した圧入方法によって接着接合させる場合の他、竿管外周面に予め接着剤を塗布して接着接合させる場合とを含んでいるが、第２の発明では、前者に限定すると共に、長手方向領域の必須位置を限定したが、作用効果は第１の発明と殆ど同じである。しかし、長手方向領域が注入孔（に対応する）位置にあるため、これに沿った接着剤の竿管長手方向に流れる勢いが強く、接着剤をより遠くにまで送ることができる。   The first invention includes the case where the adhesive is adhesively bonded by the press-fitting method through the injection hole, and the case where the adhesive is preliminarily applied and bonded to the outer peripheral surface of the tubule. In the invention, while limiting to the former and limiting the essential position of the longitudinal direction region, the function and effect are almost the same as in the first invention. However, since the longitudinal region is located at (corresponding to) the injection hole, there is a strong momentum of the adhesive flowing along the longitudinal direction of the duct along the longitudinal direction, and the adhesive can be sent further.

第３の発明では、凸条の延伸方向が、注入孔から遠ざかる方向であるため、接着剤の流れの勢いを効率的に利用できて凸条に沿いつつ竿管の円周方向に向かう流れを生じさせることができる。   In the third invention, since the extending direction of the ridge is a direction away from the injection hole, the flow of the adhesive can be used efficiently, and the flow toward the circumferential direction of the tub tube while following the ridge. Can be generated.

筒状部品内面の横断面形状が真円から偏寄した形状（例えば、楕円）であって、楕円の短軸方向のように竿管表面との隙間が狭くなって周方向への接着剤の流れが阻害される虞がある場合でも、凸条の高さ分の流路空間を確保できれば周方向への接着剤の流れが阻害され難いし、注入孔を使用した接着剤注入の場合、注入孔から遠く離れると接着剤の流れ勢いが弱くなるが、第４の発明では、凸条の竿管長手方向の間隔は注入孔から遠ざかるほど狭くなっているため、この付近の周方向流路を形成している前後に隣接した凸条間の間隔が狭いため、隣接凸条で形成される周方向流路において、筒状部品内面と竿管表面との隙間が凸条の高さに保持され易い。従って、接着剤を周方向に案内し易く、筒状部品の接着接合強度が向上する。   The cross-sectional shape of the inner surface of the cylindrical part is a shape deviated from a perfect circle (for example, an ellipse). Even if there is a risk of the flow being obstructed, the flow of the adhesive in the circumferential direction is difficult to be obstructed if the flow path space for the height of the ridges can be secured. Although the flow rate of the adhesive is weakened far away from the hole, in the fourth invention, the distance in the longitudinal direction of the ridges of the ridges becomes narrower as it goes away from the injection hole. Since the interval between the adjacent ridges before and after forming is narrow, in the circumferential flow path formed by the adjacent ridges, the gap between the inner surface of the cylindrical part and the surface of the tub tube is held at the height of the ridges. easy. Therefore, it is easy to guide the adhesive in the circumferential direction, and the adhesive bonding strength of the cylindrical part is improved.

第５の発明では、長手方向領域の円周方向両側に凸条が複数ずつ配設されて長手方向領域を区画形成しており、各側の凸条に挟まれた該長手方向領域の幅は前記注入孔から遠ざかるほど狭くなっているので、注入孔を使用した接着剤注入の場合、注入孔から竿管の長手方向に離れるに従って竿管長手方向に流れる接着剤の一部が各凸条に受け止められて各凸条に沿って周方向に流れる。従って、接着剤の円周方向案内の効果を高くでき、筒状部品の接着接合強度が向上する。   In the fifth invention, a plurality of ridges are arranged on both sides in the circumferential direction of the longitudinal region to define the longitudinal region, and the width of the longitudinal region sandwiched between the ridges on each side is Since it is narrower away from the injection hole, in the case of adhesive injection using the injection hole, a part of the adhesive that flows in the longitudinal direction of the soot tube is separated from each injection line in the longitudinal direction of the soot tube. It is received and flows in the circumferential direction along each ridge. Therefore, the effect of the circumferential guide of the adhesive can be enhanced, and the adhesive joint strength of the cylindrical part is improved.

図１は、本発明に係る釣竿の側面図であり、図２は図１の筒状部品２０を接着固定する前の状態の要部の拡大図であり、（ａ）はその筒状部品の平面図、（ｂ）は竿管１０の要部の平面図、（ｃ）は竿管１０の要部に対して筒状部品を装着させた状態の側面図である。この例の釣竿は元竿竿管１０に対して中竿１２等を継ぎ合わせたものである。元竿竿管１０等の各竿管は、エポキシ樹脂等の合成樹脂をマトリックスとし、炭素繊維等の強化繊維で強化した繊維強化樹脂製竿管である。   FIG. 1 is a side view of a fishing rod according to the present invention, FIG. 2 is an enlarged view of a main part in a state before the cylindrical part 20 of FIG. 1 is bonded and fixed, and FIG. FIG. 4B is a plan view of a main part of the soot tube 10, and FIG. 5C is a side view of a state where a cylindrical part is attached to the main part of the soot tube 10. The fishing rod in this example is obtained by joining a middle rod 12 and the like to the main rod tube 10. Each steel pipe such as the main steel pipe 10 is a fiber reinforced resin steel pipe made of a synthetic resin such as an epoxy resin and reinforced with a reinforcing fiber such as carbon fiber.

この例での筒状部品２０は、適宜な合成樹脂材を射出成形して筒状に成形し、その適宜な位置に固定フード２０Ａを一体形成しており、別部品である移動フード部品２２を装着可能に構成したリール装着部品であり、リール１４を装着固定する筒状の部品である。図１の番号１６は釣糸導入部である。この例では、筒状部品２０には、移動フード部品が位置する領域の適宜位置に径方向に貫通した注入孔２０Ｈを設けている。   The cylindrical component 20 in this example is formed by injection molding an appropriate synthetic resin material into a cylindrical shape, and a fixed hood 20A is integrally formed at an appropriate position. It is a reel mounting part configured to be mountable, and is a cylindrical part for mounting and fixing the reel 14. Reference numeral 16 in FIG. 1 denotes a fishing line introducing portion. In this example, the cylindrical part 20 is provided with an injection hole 20H penetrating in the radial direction at an appropriate position in a region where the movable hood part is located.

一方、元竿竿管１０には、筒状部品２０が装着された状態の前記注入孔２０Ｈに対応する位置２０Ｈ’を基準にして、その元側領域と先側領域とに分かれ、指向方向が元竿竿管を垂直に横切る垂直線に対して元側領域と先側領域とが互いに概ね対称になった各２列の異なる複数条の凸条が設けられている。前記先側領域には、平面視において、元竿竿管１０の中心軸線ＣＬの左右両側に分かれて、夫々の列に複数条の凸条３０Ａ又は３０Ｂが配設されており、左側の列の凸条３０Ｂと右側の列の凸条３０Ａとは、中心軸線ＣＬに対して互いに概ね対称な延伸角度になるように配設されている。また、前記元側領域にも、平面視において、中心軸線ＣＬの左右両側に分かれて、夫々の列に複数条の凸条３０Ａ’又は３０Ｂ’が配設されており、左側の列の凸条３０Ｂ’と右側の列の凸条３０Ａ’とは、中心軸線ＣＬに対して互いに概ね対称な延伸方向になるように配設されている。   On the other hand, the main tube 10 is divided into its original region and the front region with reference to the position 20H ′ corresponding to the injection hole 20H in the state where the cylindrical part 20 is mounted, and the directing direction is There are provided a plurality of different ridges in two rows each having an original area and a front area substantially symmetrical with respect to a vertical line perpendicularly crossing the main tube. In the front side region, in plan view, it is divided into the left and right sides of the center axis CL of the main tube 10, and a plurality of ridges 30A or 30B are arranged in each row, and the left side row The ridges 30B and the ridges 30A in the right column are arranged so as to have substantially symmetric stretching angles with respect to the central axis CL. In addition, the original region is also divided into the left and right sides of the central axis CL in a plan view, and a plurality of ridges 30A ′ or 30B ′ are arranged in each row, and the ridges in the left row are arranged. 30B ′ and the ridges 30A ′ in the right column are arranged so as to have extending directions that are substantially symmetrical with respect to the central axis CL.

複数条の凸条３０Ａと他側の複数条の凸条３０Ｂとの間には、前記位置２０Ｈ’の元竿竿管の長手方向に延長した位置に、元竿竿管の長手方向に沿った長手方向領域Ｚ１が存在している。また、複数条の凸条３０Ａ’と他側の複数条の凸条３０Ｂ’との間にも、前記位置２０Ｈ’の元竿竿管の長手方向に延長した位置に、元竿竿管の長手方向に沿った長手方向領域Ｚ２が存在している。共に、説明の便宜上、各領域に斜線を施している。この領域に筒状部品２０を被着させた場合に注入孔２０Ｈに対応する元竿竿管表面での位置を記号２０Ｈ’で示しているが、注入孔２０Ｈから接着剤を圧入すると、元竿竿管表面の位置２０Ｈ’付近では四方に広がり、その様子を矢印で示している。しかし、位置２０Ｈ’を遠く離れた位置では、前記長手方向領域Ｚ１，Ｚ２を介して接着剤が主に元竿竿管の長手方向に流れる。また、各凸条の存在によって、注入孔２０Ｈの位置していない円周方向の位置、即ち、ここでは径方向反対側に向かって接着剤を流すことが容易になる。   Between the multiple ridges 30A and the multiple ridges 30B on the other side, along the longitudinal direction of the main tube at the position extended in the longitudinal direction of the main tube at the position 20H ′. A longitudinal region Z1 exists. In addition, between the plurality of ridges 30A ′ and the other plurality of ridges 30B ′, the length of the main tube is extended to the position extending in the longitudinal direction of the main tube at the position 20H ′. There is a longitudinal region Z2 along the direction. In both cases, each region is hatched for convenience of explanation. When the cylindrical part 20 is attached to this region, the position on the surface of the main tube corresponding to the injection hole 20H is indicated by the symbol 20H ′. In the vicinity of the position 20H 'on the surface of the soot tube, it spreads in all directions, and this is indicated by arrows. However, at a position far away from the position 20H ', the adhesive mainly flows in the longitudinal direction of the main pipe through the longitudinal regions Z1 and Z2. Further, the presence of each protrusion makes it easier to flow the adhesive toward the circumferential position where the injection hole 20H is not located, that is, the opposite side in the radial direction here.

この接着剤の流れの内の元竿竿管の長手方向の流れに対して、夫々の凸条３０Ａ，３０Ｂ，３０Ａ’，３０Ｂ’の延伸方向はその流れに沿っている。即ち、各凸条の、長手方向領域の側の凸条端部から見た延伸方向は、接着剤の元竿竿管の長手方向の流れに沿った方向である。更に言い換えれば、図示する各角度θ１，θ２，θ１’，θ２’が鋭角である。逆に言えば、これらの角度が鈍角であれば流れに沿っているとはいえない。また、９０度の場合も流れには沿ってはいない。なお、この例では、各角度θ１，θ２，θ１’，θ２’は同じ角度としているが、夫々任意に異なっていてもよい。この例では、各角度は５０度〜７０度の範囲の角度に設定している。   With respect to the longitudinal flow of the main pipe in the adhesive flow, the extending directions of the respective protrusions 30A, 30B, 30A ', 30B' are along the flow. That is, the extending | stretching direction seen from the protruding line | wire end part by the side of the longitudinal direction of each protruding line is a direction along the flow of the longitudinal direction of the main pipe of an adhesive agent. In other words, the illustrated angles θ1, θ2, θ1 ′, and θ2 ′ are acute angles. Conversely, if these angles are obtuse, they cannot be said to be along the flow. Also, the case of 90 degrees does not follow the flow. In this example, the angles θ1, θ2, θ1 ′, and θ2 ′ are the same angle, but may be arbitrarily different from each other. In this example, each angle is set to an angle in the range of 50 degrees to 70 degrees.

上記実施形態例では、夫々の竿管長手方向の列を成す各複数の凸条間における元竿竿管長手方向の間隔は同じに構成しているが、各列において、接着剤流れの終端に行くに従って間隔を狭くするように構成することもできる。こうすれば、第４の発明の作用効果で説明したように、接着剤流れの終端に近い位置の隣接凸条で形成する周方向流路ほど、筒状部品内面と竿管表面との隙間が凸条の高さに保持され易く、接着剤の流れの勢いが低下する流れの下流側においても、元竿竿管の円周方向に接着剤を案内し易い。   In the above embodiment example, the spacing in the longitudinal direction of the main tube between the plurality of ridges forming the row in each longitudinal direction is the same, but in each row, at the end of the adhesive flow It can also be configured to narrow the interval as it goes. In this way, as explained in the operational effect of the fourth invention, the gap between the inner surface of the cylindrical part and the surface of the soot tube becomes larger in the circumferential flow path formed by the adjacent ridges located near the end of the adhesive flow. It is easy to hold the adhesive at the height of the ridges, and to guide the adhesive in the circumferential direction of the main pipe even on the downstream side of the flow where the momentum of the adhesive flow decreases.

ここで、各凸条はスクリーン印刷によって成形すると容易に成形でき、各凸条の高さは０．０３ｍｍ〜０．２ｍｍ程度が好ましいが、これに限るものではない。このスクリーン印刷のインクの樹脂材としては、エポキシ系やウレタン系の樹脂、又はＵＶ硬化型樹脂（紫外線硬化型樹脂）が使用可能である。また、各凸条は、１本の線条としているが、その凸条ラインに沿って複数本の線条が直列状に並んだものでもよく、また、点状のものをラインに沿って多数個並べて形成してもよい。また、図２の上では、各凸条を直線状に描いているが、これらが曲線状になっていてもよい。   Here, each ridge can be easily formed by screen printing, and the height of each ridge is preferably about 0.03 mm to 0.2 mm, but is not limited thereto. As the resin material for the screen printing ink, an epoxy resin or a urethane resin, or a UV curable resin (ultraviolet curable resin) can be used. In addition, each ridge is a single line, but a plurality of lines may be arranged in series along the ridge line. They may be formed side by side. In addition, in FIG. 2, each ridge is drawn in a straight line, but these may be curved.

例えば、図３にはそうした曲線状の凸条に構成した例を開示している。（ａ）は平面図、（ｂ）は側面図である。各凸条の曲線ラインは、元竿竿管の長手方向における接着剤の流れの下流側に向かって凸となる曲線である。この曲線の凸条では、図３の平面図（ａ）の状態を下側に見るように、上方側から接着剤を注入する場合は、各凸条に沿って接着剤が流れる際に、その勢いが衰えた場合に、注入側である位置２０Ｈ’の径方向反対側方向に接着剤が流れ易い。   For example, FIG. 3 discloses an example in which such curved ridges are configured. (A) is a top view, (b) is a side view. The curved line of each ridge is a curve which becomes convex toward the downstream side of the adhesive flow in the longitudinal direction of the main pipe. In the case of the curved line, when the adhesive is injected from the upper side so that the state of the plan view (a) of FIG. 3 is viewed on the lower side, when the adhesive flows along each line, When the momentum declines, the adhesive tends to flow in the direction opposite to the radial direction of the position 20H ′ on the injection side.

また、図４は、他の変形例を図示しており、（ａ）は平面図、（ｂ）は側面図である。長手方向領域Ｚ１’とＺ２’が、夫々、流れの下流方向に行くに従って幅狭になっており、第５の発明の作用効果で説明したように、注入孔から接着剤を注入した場合、注入孔から竿管の長手方向に離れるに従って竿管長手方向に流れる接着剤の一部が各凸条に受け止められて各凸条に沿って周方向に流れる。従って、凸条に沿った接着剤の円周方向案内の効果を高くできる。
なおこの図４の例では、各凸条を２本の線条を直列に並べて形成している。 FIG. 4 shows another modification, in which (a) is a plan view and (b) is a side view. The longitudinal regions Z1 ′ and Z2 ′ are narrower as they go in the downstream direction of the flow, respectively. As described in the effect of the fifth invention, when the adhesive is injected from the injection hole, A part of the adhesive flowing in the longitudinal direction of the soot tube is received by each convex strip and flows in the circumferential direction along each convex strip as it is separated from the hole in the longitudinal direction of the soot tube. Therefore, the effect of the circumferential guide of the adhesive along the ridges can be enhanced.
In the example of FIG. 4, each protrusion is formed by arranging two filaments in series.

図５は発明１（請求項１）に含まれている一形態例を示している。図４までにおいて説明した例と異なり、筒状部品２０には注入孔は必要でないため設けていない。即ち、接着接合の際には、予め接着剤を元竿竿管１０の所定領域の表面に塗布しておき、それが乾燥する前に、元竿竿管の先側端か元側端の何れかから筒状部品２０を挿入させる。この例の場合は、元竿竿管の元側端から挿入しており、この挿入によって接着剤が筒状部品の内面によって引き連れられた動きをし、接着剤の流れとはこのことをいう。従って、この例では、接着剤の流れは矢印方向になる。   FIG. 5 shows an embodiment included in the invention 1 (Claim 1). Unlike the example described up to FIG. 4, the cylindrical part 20 is not provided with an injection hole because it is not necessary. That is, at the time of adhesive bonding, an adhesive is applied in advance to the surface of a predetermined region of the main tube 10, and before it dries, either the front end or the front end of the main tube is dried. The cylindrical part 20 is inserted from above. In the case of this example, it is inserted from the original side end of the main steel pipe, and by this insertion, the adhesive is moved by the inner surface of the cylindrical part, and the flow of the adhesive means this. Therefore, in this example, the flow of the adhesive is in the direction of the arrow.

このため、各列の凸条３０Ａ，３０Ｂの延伸方向は接着剤の流れに沿っており、それだけ接着剤を円周方向に案内し易い。しかし、各凸条の延伸方向がこの例とは逆に、接着剤の流れに逆らう方向であってもよい。なお、こうした接着接合方法による場合は、各列の凸条間隔や長手方向領域の幅については、種々の変形を許容し、接着剤の円周方向への案内作用としてはそれらの間に大差は無い。
以上の説明では、筒状部品としてはリール装着部品を例としたが、その他、グリップ部にも適用できる。例えば、ＥＶＡ等の発泡性部材を外側表面に設ける筒状部品を、竿管に接着接合させる場合である。 For this reason, the extending direction of the ridges 30A and 30B in each row is along the flow of the adhesive, and the adhesive is easily guided in the circumferential direction accordingly. However, the extending direction of each protrusion may be opposite to the flow of the adhesive, contrary to this example. In addition, in the case of such an adhesive joining method, various deformations are allowed for the spacing between the protruding stripes of each row and the width of the longitudinal direction region, and there is a large difference between them as a guide action in the circumferential direction of the adhesive. No.
In the above description, the reel-mounted component is taken as an example of the cylindrical component, but it can also be applied to the grip portion. For example, it is a case where a cylindrical part provided with a foaming member such as EVA on the outer surface is adhesively bonded to a soot tube.

本発明は、筒状のリール装着部品を設けた釣竿等、竿管に筒状部品を接着固定する釣竿に利用できる。   INDUSTRIAL APPLICABILITY The present invention can be used for a fishing rod in which a cylindrical component is bonded and fixed to a rod such as a fishing rod provided with a cylindrical reel mounting component.
