Description

本発明はルアーロッドに関する。   The present invention relates to a luer rod.

ルアーロッドは、片手で操作が容易なように軽量で操作性が良いように形成されなければならない。従って、竿杆自体は細径に形成される。こうしたルアーロッドの例が下記特許文献１に開示されている。この文献１では、大撓み時の捩り剛性向上のため、撓みの期待される竿杆露出領域（ハンドル部以外の領域）に傾斜方向繊維層を設ける構造が開示されている。この文献１のルアーロッドもそうであるが、ルアーロッドは片手で操作されるものの、リール固定装置の後側に、片手で握れる長さの後側グリップ部を設けているタイプのものでは、一方の手でここを握り、他方の手でリール固定装置部を握って投擲操作を行う場合がある。
特開２００２−３４５３６５号公報 The luer rod must be formed so as to be light and easy to operate so that it can be easily operated with one hand. Accordingly, the ridge itself is formed with a small diameter. An example of such a luer rod is disclosed in Patent Document 1 below. This document 1 discloses a structure in which an inclined direction fiber layer is provided in a wrinkle-exposed region (region other than the handle portion) where bending is expected in order to improve torsional rigidity during large bending. The same applies to the lure rod in this document 1, but the lure rod is operated with one hand, but in the type in which a rear grip portion having a length that can be grasped with one hand is provided on the rear side of the reel fixing device, There is a case where a throwing operation is performed by grasping here with one hand and grasping the reel fixing device with the other hand.
JP 2002-345365 A

然しながら、この場合、必然的に左右の手でロッドを捩るように操作する。既述の如く、ルアーロッドは細径であるため、一般に捩りに対して弱い。等方性物質で形成した管状体の場合、肉厚を１ｍｍとすると、外径が１０ｍｍの管状体を外径７ｍｍに小径化すると、捩り剛性は１／３程に大きく低下する。このように、小径化は大きく捩り剛性を低下させる。
依って、本発明の解決しようとする課題は、両手を使った投擲操作の際の捩り剛性を向上させた釣竿を提供することである。 However, in this case, the rod is inevitably operated by twisting with the left and right hands. As described above, since the lure rod has a small diameter, it is generally weak against twisting. In the case of a tubular body formed of an isotropic material, assuming that the wall thickness is 1 mm, the torsional rigidity is greatly reduced by about 1/3 when the tubular body having an outer diameter of 10 mm is reduced to an outer diameter of 7 mm. Thus, the reduction in diameter greatly reduces the torsional rigidity.
Therefore, the problem to be solved by the present invention is to provide a fishing rod having improved torsional rigidity during a throwing operation using both hands.

上記目的に鑑み本発明の請求項１では、繊維強化樹脂製竿杆の後方部に装着され、リール載置部を含み、合成樹脂で一体形成されて竿杆に套嵌装着されたリールシート本体と、１対のフードとを有するリール固定装置と、リールシート本体の後端よりも後方に離れて片手で握れる長さを有する後側グリップ部とを具備し、少なくともリールシート本体の途中位置から前記後側グリップ部の途中位置にまで亘る竿杆には、強化繊維を竿杆の軸長方向に対して傾斜方向に指向させた傾斜層を有しており、強化繊維が円周方向に指向した層と軸長方向に指向した層とを有する第１プリプレグと、強化繊維が円周方向に指向した層と軸長方向に指向した層とを有する第２プリプレグとの巻回層を設けており、該第２プリプレグはその台形状の元部角部がカットされた形状であり、該第１、第２のプリプレグ巻回層の上であって前記カット領域を補って、強化繊維が傾斜方向に指向した第３プリプレグを巻回して前記傾斜層を形成していることを特徴とするルアーロッドを提供する。   In view of the above-described object, according to claim 1 of the present invention, a reel sheet main body mounted on the rear portion of the fiber reinforced resin cage, including a reel placement portion, integrally formed of synthetic resin and fitted on the collar. And a reel fixing device having a pair of hoods, and a rear grip portion having a length that can be gripped with one hand away from the rear end of the reel seat body, and at least from the middle position of the reel seat body The heel extending to the middle position of the rear grip portion has an inclined layer in which the reinforcing fibers are oriented in an inclined direction with respect to the axial length direction of the heel, and the reinforcing fibers are oriented in the circumferential direction. A winding layer of a first prepreg having a layer oriented in the axial length direction and a second prepreg having a layer oriented in the circumferential direction of the reinforcing fibers and a layer oriented in the axial length direction is provided. The second prepreg has a trapezoidal base corner The cut layer is formed on the first and second prepreg winding layers, supplementing the cut region, and winding the third prepreg with reinforcing fibers oriented in the tilt direction to form the tilt layer. A lure rod is provided.

請求項２では、リール固定装置の前側に前側グリップ部が配設されている場合は該前側グリップ部の前側竿杆部位に比べて、前側グリップ部が無い場合はリール固定装置の前側竿杆部位に比べて、前記傾斜方向指向の強化繊維比率が高くてなる請求項１記載の釣竿を提供する。   According to claim 2, when the front grip portion is provided on the front side of the reel fixing device, the front hook portion of the reel fixing device is provided when the front grip portion is not provided, compared to the front hook portion of the front grip portion. The fishing rod according to claim 1, wherein the ratio of reinforcing fibers oriented in the inclination direction is higher than that of the fishing rod.

請求項３では、リール固定装置の前側に前側グリップ部が配設されている場合は該前側グリップ部から後側グリップ部領域内にまで亘って強化繊維が少なくとも軸長方向に指向した層と傾斜方向に指向した層とを具備し、前側グリップ部とリール固定装置との長さ範囲内において、前側グリップ部が無い場合はリール固定装置から後側グリップ部領域内にまで亘って強化繊維が少なくとも軸長方向に指向した層と傾斜方向に指向した層とを具備し、リール固定装置の長さ範囲内において、後方に向かって軸長方向指向強化繊維の割合が減少すると共に傾斜方向指向強化繊維の割合が増大する漸変部を有し、該漸変部を出て後側グリップ部領域内に至るまでは前記傾斜方向指向強化繊維の割合は漸変部の前端部よりも大きく、軸長方向指向強化繊維の割合は小さい請求項１又は２記載のルアーロッドを提供する。   According to a third aspect of the present invention, when the front grip portion is disposed on the front side of the reel fixing device, the reinforcing fibers are inclined at least in the axial length direction from the front grip portion to the rear grip portion region. If there is no front grip portion within the length range of the front grip portion and the reel fixing device, at least the reinforcing fiber extends from the reel fixing device to the rear grip portion region. A layer oriented in the axial direction and a layer oriented in the tilt direction, and within the length range of the reel fixing device, the ratio of the axial length direction reinforcing fibers decreases toward the rear and the tilt direction oriented reinforcing fibers The proportion of the reinforcing fiber oriented in the inclined direction is larger than that of the front end portion of the gradual portion until it exits the gradual portion and reaches the rear grip region. Directional enhancement Proportion of Wei provides lure rod small claim 1 or 2, wherein.

請求項４では、１対のフードが、前方の固定フードと後方の移動フードであり、該移動フードはその後側に配設されてリールシート本体上の雌ねじと螺合して回動しつつ前後に移動するナット部材によって駆動される構成であり、リールシート本体の後端と後側グリップ部前端近くとの間は、ナット部材が退避移動可能な外径である請求項１〜３までの内の何れか１記載のルアーロッドを提供する。   In claim 4, the pair of hoods are a front fixed hood and a rear movable hood, and the movable hood is disposed on the rear side and is screwed with a female screw on the reel seat body to rotate back and forth. An inner diameter of the reel seat main body between the rear end of the reel seat main body and the vicinity of the front end of the rear grip portion is an outer diameter at which the nut member can be retracted and moved. A luer rod according to any one of the above is provided.

請求項１では、リール固定装置部の竿杆はリールシート本体によって補強された状態であり、このリールシート本体は後側グリップ部と分離しているため、投擲操作時に、前側の手でリール固定装置部を握り、後側の手で後側グリップ部を握って操作すれば、リールシート本体の後側領域（分離間領域）に大きな捩り負荷が作用する。従って、少なくともリールシート本体の途中位置から後側グリップ部の途中位置にまで亘る竿杆に傾斜方向繊維層を設ければ、こうした際の捩り剛性を向上させることができる。   According to the first aspect of the present invention, the reel of the reel fixing device portion is reinforced by the reel sheet main body, and the reel sheet main body is separated from the rear grip portion. If the device portion is gripped and the rear grip portion is gripped and operated by the rear hand, a large torsional load acts on the rear region (inter-separation region) of the reel sheet main body. Therefore, the torsional rigidity in such a case can be improved if the inclined direction fiber layer is provided at least on the heel extending from the middle position of the reel sheet main body to the middle position of the rear grip portion.

請求項２では、撓みの期待される竿杆露出部位（上記前側竿杆部位）にも傾斜方向繊維層を設けることはあるが、ここよりも傾斜方向指向の強化繊維比率を高く形成するため、それだけハンドル部の捩り剛性が向上する。   In claim 2, although the inclined direction fiber layer is also provided in the wrinkle exposed part (the front side wrinkle part) where bending is expected, in order to form a higher reinforcing fiber ratio in the inclined direction than here, Accordingly, the torsional rigidity of the handle portion is improved.

請求項３では、（前側グリップ部又は）リール固定装置の長さ範囲内において傾斜方向指向強化繊維の割合が増大し、後側グリップ部領域内までは前記割合は漸変部の前端部よりも大きいため、この間の竿杆の捩り剛性が向上する。また、こうして捩り剛性を向上させつつも、この領域に撓みを予定しない釣竿の場合、軸長方向強化繊維割合を減少させることができ、このため、後側グリップ部領域内に至るまでは捩り剛性を向上させる割りに小径化でき、軽量化に寄与する。リール固定装置から後方領域に強い撓みを予定しないのは、釣竿後端を腹にあてがって、ポンピングを行うような使用を想定していない種類の釣竿である。   In claim 3, the proportion of the inclination-oriented reinforcing fibers increases within the length range of the reel fixing device (the front grip portion), and the proportion is higher than the front end portion of the gradually changing portion until the rear grip portion region. Since it is large, the torsional rigidity of the heel during this time is improved. In addition, in the case of a fishing rod that improves torsional rigidity but does not plan to bend in this region, the ratio of reinforcing fibers in the axial length direction can be reduced, so that the torsional rigidity reaches the rear grip region. The diameter can be reduced to improve the weight, contributing to weight reduction. It is a type of fishing rod that is not supposed to be used for pumping by placing the rear end of the fishing rod against the belly and does not expect strong deflection from the reel fixing device to the rear region.

請求項４では、リールシート本体の後端と後側グリップ部前端近くの間はナット部材が退避移動可能な外径であるため、小径であり、またこの間の竿杆にはリールシート本体が至っていないため、結果的に補強されておらず、捩り負荷に対しても弱い。また、ナット部材を回動させてリール脚を締結する構造のため、それだけ竿杆には強く捩り負荷が作用する。従って、こうした小径で捩り負荷の作用し易い構造の釣竿の場合に、傾斜方向繊維層を設けることは捩り剛性向上に大きく役立つ。   According to a fourth aspect of the present invention, the nut member has a small outer diameter between the rear end of the reel sheet main body and the front end of the rear grip portion, so that the reel member has a small diameter. As a result, they are not reinforced and are weak against torsional loads. Further, the structure is such that the reel member is fastened by rotating the nut member, so that a torsional load is applied to the heel as much. Therefore, in the case of a fishing rod having a small diameter and a structure that is easily subjected to torsional load, it is greatly useful to improve the torsional rigidity by providing the inclined direction fiber layer.

以下、本発明を添付図面に示す実施形態例に基づき、更に詳細に説明する。
図１は本発明に係るルアーロッドの要部側面図と、その竿杆の縦断面図による径方向拡大部分図である。エポキシ樹脂等の合成樹脂をマトリックとし、炭素繊維等の強化繊維で強化した繊維強化合成樹脂製竿杆１０の後方部所定位置には、リールを載置させるリール載置部１２Ｓを有し、合成樹脂で形成された概ね筒状のリールシート本体１２を套嵌させ、接着固定している。この本体の前記リール載置部の前側部には固定フードＦ１を一体に形成し、これに対向させて後側には移動フードＦ２を設けている。 Hereinafter, the present invention will be described in more detail based on an embodiment shown in the accompanying drawings.
FIG. 1 is a side view of a main part of a luer rod according to the present invention and a radially enlarged partial view of a longitudinal section of the rod. A synthetic resin such as an epoxy resin is used as a matrix, and a reel mounting portion 12S for mounting a reel is provided at a predetermined position in the rear portion of the fiber-reinforced synthetic resin cage 10 reinforced with a reinforcing fiber such as carbon fiber. A generally cylindrical reel sheet main body 12 made of resin is fitted and fixed by adhesion. A fixed hood F1 is integrally formed on the front side portion of the reel mounting portion of the main body, and a movable hood F2 is provided on the rear side so as to face the fixed hood F1.

該移動フードは、その直後に設けられて前記リールシート本体外周に設けた雄ねじに螺合させたナット部材Ｎを回動させて前後に移動可能に構成されている。これらでリール固定装置を形成している。また、リールシート本体１２は領域Ｌ１２の範囲に設けられており、その前側端部の前方所定領域ＬＦは前側グリップ部ＦＧとして形成している。この前側グリップ部から前記リール載置部の径方向反対側領域にまで亘って、把持感が良く、グリップ部として適する発泡性樹脂やコルク材による握り部材を被覆させている。   The moving hood is configured to be movable back and forth by rotating a nut member N that is provided immediately thereafter and screwed into a male screw provided on the outer periphery of the reel seat body. These form a reel fixing device. Further, the reel sheet main body 12 is provided in the range of the region L12, and a predetermined front region LF at the front end thereof is formed as a front grip portion FG. From this front side grip part to the radial direction opposite side area | region of the said reel mounting part, a grip feeling is good and the grip member by a foamable resin and a cork material suitable as a grip part is coat | covered.

一方、リールシート本体１２の後端から所定距離離隔して、領域ＬＲに後側グリップ部ＲＧを設けており、その後端部には尻栓２０を設けている。この後側グリップ部にも、把持感が良く、グリップ部として適する発泡性樹脂やコルク材による握り部材を被覆させている。前記リールシート本体１２後端と後側グリップ部との間の竿杆１０の上には、ステンレス材等のリング部材Ｒが套嵌されており、竿杆１０を保護すると共に、後側グリップ部の前端面を保護している。この後側グリップ部前端面保護部を除いたリールシート本体後端の後方領域ＬＳは、ナット部材Ｎが後退移動するために、それが可能なように小径に形成されている。   On the other hand, a rear grip RG is provided in the region LR at a predetermined distance from the rear end of the reel sheet body 12, and a tail plug 20 is provided at the rear end. The rear grip portion also has a good grip feeling and is covered with a gripping member made of foamable resin or cork material suitable as the grip portion. A ring member R made of stainless steel or the like is fitted over the collar 10 between the rear end of the reel sheet main body 12 and the rear grip section to protect the collar 10 and the rear grip section. Protects the front edge of the. The rear region LS at the rear end of the reel sheet main body excluding the rear grip portion front end surface protecting portion is formed with a small diameter so that the nut member N can move backward.

後手で後側グリップ部を握り、前手でリール固定装置部を把持して投擲操作を行えば、この間の領域に捩り負荷が作用する。特に、合成樹脂材のリールシート本体１２が途切れて、該リールシート本体と後側グリップ部との間に位置して、捩りに対して竿杆１０を強く補強していない小径の領域ＬＳが問題となる。また、この例では、リールの脚をナット部材を締め込んで締結するため、その際に竿杆に捩り負荷が作用する。   If the rear grip part is gripped by the rear hand and the reel fixing device part is gripped by the front hand and the anchoring operation is performed, a torsional load acts on the region between them. In particular, the reel sheet main body 12 made of a synthetic resin material is interrupted, and the small-diameter region LS located between the reel sheet main body and the rear grip portion and not strongly reinforcing the flange 10 against torsion is a problem. It becomes. In this example, the reel leg is fastened by tightening the nut member, and at that time, a torsional load acts on the flange.

こうした捩り負荷に対して竿杆の捩り剛性を向上させるために、傾斜方向指向強化繊維の層を設ける。従来の考えでは、こうしたリール固定装置領域とその後方領域で捩り負荷が大きな問題となることは無かった。それは竿杆がある程度の大きさの外径と肉厚を有しており、それで捩り負荷に耐えることができたからである。しかし、釣竿の軽量化を狙って、更に小径化させようとすれば（例えば外径８ｍｍ弱）、捩り負荷の影響が表面化し、対策が必要となる。そこで、竿杆の層の中で、最も効果的な最外層に傾斜方向指向強化繊維の層を設ける。   In order to improve the torsional rigidity of the heel against such a torsional load, a layer of reinforcing fibers oriented in the inclination direction is provided. Conventionally, the torsional load did not become a big problem in the reel fixing device region and the rear region. This is because the ridge has a certain size of outer diameter and wall thickness, and was able to withstand torsional loads. However, if an attempt is made to further reduce the diameter of the fishing rod in order to reduce the weight of the fishing rod (for example, an outer diameter of less than 8 mm), the effect of the torsional load becomes surface and countermeasures are required. Therefore, an inclination direction-oriented reinforcing fiber layer is provided as the most effective outermost layer among the heel layers.

ここでの釣竿は、リール固定装置領域とその後方領域には、特に大きな曲げ負荷を作用させる使用形態を考えていないルアーロッドのため、リール固定装置のリール載置部１２Ｓの長さ範囲程度内に竿杆の積層の漸変部Ｃ−Ｄを設け、この範囲で、その前方領域Ａ−Ｃよりも軸長方向指向と円周方向指向の強化繊維の層ＪＥＳの割合を少なくし、その後方領域Ｄ−Ｅでは、漸変部にて減少したその割合を概ね維持している。逆に、傾斜方向指向の強化繊維の層ＫＳＳの割合は、漸変部の前方領域Ａ−Ｃが少なく、漸変部で後方に向かって割合が大きくなり、その後方領域Ｄ−Ｅでは漸変部にて増大したその割合を概ね維持している。   Since the fishing rod here is a luer rod that does not consider a usage pattern in which a large bending load is applied to the reel fixing device region and the rear region thereof, it is within the length range of the reel mounting portion 12S of the reel fixing device. In this range, the ratio of the axial length direction-oriented and circumferential direction-oriented reinforcing fiber JES is less than that of the front area A-C, and the rear thereof In the region D-E, the ratio that has decreased at the gradually changing portion is generally maintained. On the contrary, the proportion of the reinforcing fiber layer KSS oriented in the inclination direction is small in the front area A-C of the gradually changing portion, the ratio increases toward the rear in the gradually changing portion, and gradually changes in the rear region D-E. The ratio which increased in the part is generally maintained.

上記竿杆１０の製造の一過程を図２に示す。芯金ＭＤに、強化繊維ＥＳ１が円周方向に指向した薄い裏打層を有し、軸長方向に指向した強化繊維ＪＳ１の層を有するプリプレグＳ１と、強化繊維ＥＳ２が円周方向に指向した薄い裏打層を有し、軸長方向に指向した強化繊維ＪＳ２の層を有するプリプレグＳ２とを巻回する。各裏打層は薄く、軸長方向層が厚く、軸長方向指向強化繊維が多い。２枚目のプリプレグＳ２は基本となる台形状の元部角部が図のようにカットされており、このカットにより軸長方向強化繊維と円周方向強化繊維とが少なくなっている。この少なくなった分に代わって、この領域に軸長方向に対して対称な±４５度方向に傾斜指向した傾斜方向指向の強化繊維ＫＳ，ＫＳ’を有するプリプレグ片Ｓ３を巻回する。これを定法に従って加圧加熱硬化させれば、図１の積層構造の竿杆１０が成形される。   A process of manufacturing the bag 10 is shown in FIG. A prepreg S1 having a thin backing layer in which the reinforcing fiber ES1 is oriented in the circumferential direction on the core metal MD, and a layer of the reinforcing fiber JS1 oriented in the axial direction, and a thin in which the reinforcing fiber ES2 is oriented in the circumferential direction A prepreg S2 having a backing layer and a layer of reinforcing fibers JS2 oriented in the axial length direction is wound. Each backing layer is thin, the axial length direction layer is thick, and there are many axial length direction reinforcing fibers. In the second prepreg S2, the base trapezoidal corner of the base is cut as shown in the figure, and this cut reduces axial length direction reinforcing fibers and circumferential direction reinforcing fibers. Instead of this reduced amount, the prepreg piece S3 having the reinforcing fibers KS and KS 'oriented in the inclination direction oriented in the direction of ± 45 degrees symmetrical to the axial length direction is wound around this region. If this is heated under pressure and cured according to a conventional method, the bag 10 having the laminated structure of FIG. 1 is formed.

プリプレグＳ３は、４５度方向指向の強化繊維のプリプレグＳ３−１と−４５度方向指向の強化繊維のプリプレグＳ３−２とを重ねたバイアスでもよく、また、±４５度方向に傾斜指向するように編んだ編組体でもよい。更には、傾斜方向は４５度が好ましいが、３０〜６０度程度でも良い。また、軸長方向に対して対称な両方向から交差させるのは、捩りがどちら方向であっても対応できるためであるが、特定方向に捩られる場合は、それに対応する一方向の傾斜でもよい。   The prepreg S3 may be a bias in which the prepreg S3-1 of the 45 degree direction-oriented reinforcing fiber and the prepreg S3-2 of the reinforced fiber of the -45 degree direction are overlapped, and may be inclined in the ± 45 degree direction. A knitted braid may be used. Furthermore, the inclination direction is preferably 45 degrees, but may be about 30 to 60 degrees. The reason for intersecting from both directions symmetric with respect to the axial length direction is that the twist can be dealt with in either direction, but when twisting in a specific direction, the inclination in one direction corresponding thereto may be used.

一例であるが、図１の位置Ａ，Ｂ，Ｃ，Ｄ，Ｅにおける竿杆の外径と、肉厚と、傾斜方向指向層の肉厚割合（比率）との実施例を示す。位置Ａは前側グリップ部の前端位置、位置Ｂは位置ＡとＣとの中間位置、位置Ｅは竿杆後端位置である。
位置 Ａ Ｂ Ｃ Ｄ Ｅ
外径（ｍｍ） ７．９ ７．９ ７．９ ７．９ ７．９
肉厚（ｍｍ） ０．６５ ０．６５ ０．６５ ０．６５ ０．６５
割合 ０．１２ ０．０９ ０．０９ ０．１８ ０．２３ As an example, an example of the outer diameter, thickness, and thickness ratio (ratio) of the inclined direction directing layer at positions A, B, C, D, and E in FIG. Position A is the front end position of the front grip, position B is an intermediate position between positions A and C, and position E is the rear end position.
Position A B C D E
Outer diameter (mm) 7.9 7.9 7.9 7.9 7.9
Thickness (mm) 0.65 0.65 0.65 0.65 0.65
Ratio 0.12 0.09 0.09 0.18 0.23

上記例では、漸変部の前端部から竿杆後端部までは同一外径、同一肉厚に形成しているが、一般には、該漸変部前端位置を１．０とすれば、外径が０．８〜１．２の範囲内に、また、肉厚が０．５〜１．２の範囲内に形成する。
一般に市販されている炭素繊維使用のプリプレグの中で、軸長方向指向の層として使用できるプリプレグと概ね同じ厚さであって、既述のバイアスプリプレグのものがある。一例を挙げれば、軸長方向強化繊維の縦弾性率が２４ｔ／ｍｍ２（２３５２００Ｎ／ｍｍ２）のプリプレグ、バイアスも強化繊維の縦弾性率が２４ｔ／ｍｍ２（２３５２００Ｎ／ｍｍ２）のプリプレグであり、内径が５ｍｍ、肉厚が０．２４ｍｍ程度の管状体とする場合、前者のプリプレグを３層巻回した場合と、前者プリプレグを２層巻回し、後者のバイアスプリプレグを１層巻回した場合とでは、後者の積層管状体の方が、約３倍の剪断弾性率（横弾性係数）を有する管状体となる。従って、外径や肉厚を厚くして重量を大きくすることなく、捩り剛性を向上できる。 In the above example, the gradually changing portion is formed with the same outer diameter and the same thickness from the front end portion to the rear end portion. However, generally, if the front end position of the gradually changing portion is 1.0, The diameter is in the range of 0.8 to 1.2, and the wall thickness is in the range of 0.5 to 1.2.
Among commercially available prepregs using carbon fibers, there are some of the above-described bias prepregs having the same thickness as a prepreg that can be used as an axially oriented layer. For example, a longitudinal reinforced fiber having a longitudinal elastic modulus of 24 t / mm 2 (235200 N / mm 2 ) and a bias prepreg having a longitudinal elastic modulus of the reinforcing fiber of 24 t / mm 2 (235200 N / mm 2 ). Yes, when a tubular body having an inner diameter of 5 mm and a wall thickness of about 0.24 mm is used, when the former prepreg is wound in three layers, the former prepreg is wound in two layers, and the latter bias prepreg is wound in one layer. In some cases, the latter laminated tubular body is a tubular body having a shear elastic modulus (transverse elastic modulus) of about 3 times. Therefore, the torsional rigidity can be improved without increasing the weight by increasing the outer diameter or the wall thickness.

以上ではルアーロッドで説明したが、両手で投擲操作を行う釣竿一般を参考として述べれば、投擲操作時に前後の握り手の間領域において竿杆に捩り負荷が作用する。従って、こうした釣竿の投擲時の前後の握り位置部間領域に、傾斜方向指向の強化繊維層を設ければ、捩り負荷に対して強くなる。   In the above description, the lure rod has been described. However, if a fishing rod that is thrown with both hands is referred to as a reference, a torsional load acts on the rod in the region between the front and rear grippers during the throwing operation. Therefore, if a reinforcing fiber layer oriented in the tilt direction is provided in the region between the grip position portions before and after the fishing rod is thrown, it becomes strong against torsional load.
