Description

本発明は、実釣時において、長さ調節が可能な釣竿に関する。   The present invention relates to a fishing rod that can be adjusted in length during actual fishing.

従来、魚釣りに用いられる釣竿の一つとして、複数の竿杆を備え、長さ調節が可能なものが知られている。このような長さ調節が可能な釣竿は、大径の竿杆（元竿）に対して、それよりも穂先側にある小径の竿杆（元上竿）を収納し、その収納状態が固定できるような構造となっている。例えば、特許文献１には、元竿の先端側内周面に第１挟圧部を形成すると共に、基端側内周面に第２挟圧部を形成し、この元竿に収納される元上竿の先端側の外周面に、周方向に沿って摩擦条面を形成した長さ調節可能な釣竿が開示されている。   2. Description of the Related Art Conventionally, as one of fishing rods used for fishing, one having a plurality of rods and capable of adjusting the length is known. A fishing rod with adjustable length accommodates a small diameter rod (former rod) on the tip side of a large diameter rod (former rod), and the storage state is fixed. It has a structure that can be done. For example, in Patent Document 1, a first pinching portion is formed on the inner peripheral surface of the front end side of the main shaft, and a second pressing portion is formed on the inner peripheral surface of the base end side, and is stored in the main rod. A fishing rod that can be adjusted in length has been disclosed in which a friction surface is formed along the circumferential direction on the outer peripheral surface on the tip side of the original upper rod.

このような構成では、実釣時において、全体の長さを短くしたい場合、前記元上竿を元竿に収納すると、前記第１挟圧部と第２挟圧部によって、元上竿が元竿内で収納、固定された状態となり、釣竿全体の長さを短くすることができる。また、元上竿に形成された摩擦条面は、周方向に沿って所定間隔で凸部を形成した構造となっており、これが摩擦条面で構成される第１挟圧部との間で摩擦力を生じさせることから、元上竿の回転を阻止して元竿と元上竿との間で相対姿勢の安定化が図れるようになっている。
実開平３−１０８３６５号 In such a configuration, when it is desired to shorten the overall length during actual fishing, when the former upper rod is housed in the former rod, the original upper rod is caused to be the original by the first clamping portion and the second clamping portion. It is in a state of being housed and fixed in the rod, and the entire length of the fishing rod can be shortened. Moreover, the friction surface formed in the upper collar has a structure in which convex portions are formed at predetermined intervals along the circumferential direction, and this is between the first pinching portion constituted by the friction surface. Since the frictional force is generated, the rotation of the upper arm is prevented, and the relative posture can be stabilized between the upper arm and the upper arm.
Japanese Utility Model Publication No. 3-108365

通常、上記したような長さ調節が可能な釣竿は、元上竿を元竿に収納した状態で、第１挟圧部と第２挟圧部が、元先竿の外周面に圧接される構成となっており、最終的な収納状態で、元上竿は元竿に対して固定、保持される。   Usually, in the fishing rod capable of adjusting the length as described above, the first pinching portion and the second pinching portion are brought into pressure contact with the outer peripheral surface of the base tip rod in a state where the upper rod is housed in the former rod. In the final storage state, the upper arm is fixed and held with respect to the former.

しかし、このような構成では、元上竿を元竿内に収納操作する際、元上竿がガタ付き易いため軸がずれ易く、また、周方向にも回転し易いため、元竿先側の内周面と元上竿の外周面とを嵌合させる際の操作性が悪いという問題がある。すなわち、元上竿がガタ付いたり周方向に回転すると、嵌合部分における摩擦条面（凹凸面など）を固定状態にする際の操作性が悪くなってしまう。   However, in such a configuration, when the upper arm is stored and operated in the front arm, the upper arm is easily rattled so that the shaft is easily displaced, and it is easy to rotate in the circumferential direction. There is a problem that the operability when fitting the inner peripheral surface with the outer peripheral surface of the former upper collar is poor. In other words, if the upper collar is rattled or rotates in the circumferential direction, the operability when the friction surface (such as the concavo-convex surface) in the fitting portion is fixed is deteriorated.

本発明は、上記した問題に基づいてなされたものであり、長さ調節が可能な釣竿において、元上竿を元竿に収納する際の操作性が良好な釣竿を提供することを目的とする。   The present invention has been made based on the above-described problem, and an object of the present invention is to provide a fishing rod that can be adjusted in length and has excellent operability when the upper rod is stored in the former rod. .

上記した目的を達成するために、本発明に係る釣竿は、元竿と、前記元竿に対して振り出し式に収納される元上竿とを備え、前記元上竿を元竿に対して伸長状態と収縮状態に保持する長さ調節機構を有しており、前記元上竿の外面には、長さ調節用の継合領域が形成されており、前記元竿の先端側内面には、前記元上竿を元竿に収納した際、前記継合領域と継合して元上竿の周方向の回転を防止する回転防止部が設けられ、前記元竿の基端側には、前記元上竿を元竿に収納した状態で前記元上竿の基端部を保持する保持部と、前記保持部に向けて元上竿の基端部を案内する案内部が設けられており、前記回転防止部と前記案内部は、元上竿の収納時に、まず、元上竿の基端部が前記案内部に案内され始め、その後、元上竿の継合領域が前記回転防止部に継合するように設置されていることを特徴とする。   In order to achieve the above-described object, a fishing rod according to the present invention includes a main rod and an upper rod that is housed in a swinging manner with respect to the former rod, and extends the upper rod relative to the former rod. A length adjusting mechanism that holds the state and the contracted state, and a joint region for length adjustment is formed on the outer surface of the former upper collar, When the upper arm is stored in the upper arm, a rotation preventing portion is provided to prevent rotation in the circumferential direction of the upper arm by joining with the joining region. A holding portion that holds the base end of the former upper collar in a state where the former upper collar is housed in the former fence, and a guide portion that guides the proximal end of the former upper collar toward the holding portion; The anti-rotation part and the guide part are configured such that when the upper collar is stowed, first, the base end part of the former upper collar starts to be guided to the guide part, and then, the joint area of the former upper collar is Characterized in that it is installed such that engagement to prevent part.

上記した構成の釣竿では、長さ調節機構によって、元上竿を元竿に対して収縮・伸長することで、全体として長さ調節が可能となる。元上竿を元竿に収納すると、元上竿の外面に形成された継合領域が元竿の先端側内面に設けられた回転防止部と継合し、かつ元上竿の基端部が元竿の基端側に設けられた保持部に保持され、収納状態が固定される。この収納動作に際し、まず、元上竿の基端部が元竿の基端側に設けられた案内部に案内され、その後、元上竿の継合領域が回転防止部に継合するため、元上竿の挿入操作時において元上竿がガタ付いたり、周方向に回転することはなく、安定した状態で収納操作が行える。   In the fishing rod having the above-described configuration, the length can be adjusted as a whole by contracting and extending the upper rod with respect to the original rod by the length adjusting mechanism. When the former upper rod is stored in the former rod, the joining area formed on the outer surface of the former upper rod is joined with the rotation preventing portion provided on the inner surface on the distal end side of the former upper rod, and the proximal end portion of the former upper rod is It is held by a holding part provided on the base end side of the main shaft, and the stored state is fixed. In this storing operation, first, the base end portion of the former upper rod is guided to the guide portion provided on the proximal end side of the former rod, and then the joining region of the former upper rod is joined to the rotation preventing portion. During the insertion operation of the upper collar, the upper collar does not rattle or rotate in the circumferential direction, and the storage operation can be performed in a stable state.

本発明によれば、元上竿と元竿との間で長さ調節が可能であり、元上竿を元竿に収納する際の操作性が良好な釣竿が得られる。   According to the present invention, the length can be adjusted between the former rod and the former rod, and a fishing rod having good operability when the former rod is stored in the former rod can be obtained.

I have. Each of these bonito has a swing-out type, and as shown in FIG. 1 (b), the length adjustment is performed by changing the first middle rod (hereinafter referred to as the former upper rod) 2 with respect to the main rod 1. This is done by storing or stretching. The fishing line fed from a reel (not shown) is introduced into the rod through a fishing line introduction guide 12 provided on the side surface of the former rod 2 and is derived from a top guide 14 provided at the tip of the tip rod 4. Is done. Moreover, each rod which comprises the fishing rod R mentioned above is formed by the well-known method which makes the prepreg sheet | seat which impregnated the reinforced fiber the synthetic resin into a tube, for example.

前記元竿１の外周には、その先端側にリールが装着されるリールシート５と、その後端側に位置するグリップ６が順次取着されており、元竿１を構成する竿管は外部に露出しない状態となっている。また、元竿１の基端部には、尻栓７が着脱自在に装着されている。   A reel seat 5 on which a reel is mounted on the front end side thereof and a grip 6 located on the rear end side thereof are sequentially attached to the outer periphery of the main bar 1, and the bar tube constituting the main bar 1 is externally attached. It is not exposed. In addition, a bottom plug 7 is detachably attached to the base end portion of the main shaft 1.

前記リールシート５は、ポリアミドやＡＢＳ樹脂などの合成樹脂によって筒状に形成されており、元竿１の外周面に取着されている。リールシート５には、リール脚を載置するリール脚載置部５ａ、リール脚を固定するための固定フード５ｂが形成されており、リール脚載置部５ａに載置されたリールは、固定フード５ｂと移動ナットとして構成される移動フード５ｃとの間で固定されるようになっている。なお、リールシート５の前方側の外周面には、移動フード５ｃが螺合されるように、雄ネジ部が形成されている。また、リールシート５のリール脚載置部５ａと反対側には、実釣時において指を掛けるようにトリガー５ｄが形成されている。   The reel sheet 5 is formed in a cylindrical shape from a synthetic resin such as polyamide or ABS resin, and is attached to the outer peripheral surface of the main shaft 1. The reel sheet 5 is formed with a reel leg placing portion 5a for placing the reel legs, and a fixing hood 5b for fixing the reel legs. The reel placed on the reel leg placing portion 5a is fixed. It is fixed between the hood 5b and a moving hood 5c configured as a moving nut. A male thread portion is formed on the front outer peripheral surface of the reel seat 5 so that the movable hood 5c is screwed together. Further, a trigger 5d is formed on the opposite side of the reel seat 5 from the reel leg mounting portion 5a so that a finger can be hooked during actual fishing.

前記グリップ６は、握り心地が良好となるように、軟質な部材、例えばＥＶＡやウレタンなどの発泡材、合成ゴム、天然ゴムなどによって形成されている。   The grip 6 is formed of a soft member, for example, a foamed material such as EVA or urethane, synthetic rubber, natural rubber, or the like so that the grip comfort is good.

前記元竿１の後端外周には、グリップ６との間に硬質樹脂（例えば、ポリアミドやＡＢＳ樹脂等）によって形成された筒状体７ａが止着されており、元竿から突出する部分に雌ネジ部７ｂが形成されている。この雄ネジ部７ｂには、緩み止め用のＯリング７ｃを介在させて前記尻栓７が螺合されている。なお、尻栓７は、合成樹脂や金属によって形成されている。   A cylindrical body 7a formed of a hard resin (for example, polyamide, ABS resin, etc.) is fixed to the outer periphery of the rear end of the main bar 1 between the grip 6 and a portion protruding from the main bar. A female screw portion 7b is formed. The butt plug 7 is screwed into the male screw portion 7b with an O-ring 7c for preventing loosening interposed. Note that the bottom plug 7 is made of synthetic resin or metal.

前記元竿１の基端側には、元上竿２が収納された際、元上竿の基端領域を保持する保持部材８が設けられている。この保持部材８は、ポリアミド、ＡＢＳ樹脂、ポリウレタン等の合成樹脂によって形成され、収納された状態の元上竿２の基端側の外周面を圧着して保持する保持部８ａと、穂先側から保持部８ａに向けて次第に縮径するようにして元上竿２の基端部を案内する案内部８ｂが一体的に設けられている。このような保持部材８は、雄ネジ部８ｃを形成しておき、前記筒状体７ａに螺合するように尻栓７に一体的に設けておくことが可能である。   A holding member 8 is provided on the base end side of the base rod 1 to hold the base region of the base rod when the base rod 2 is stored. The holding member 8 is formed of a synthetic resin such as polyamide, ABS resin, polyurethane, and the like. The holding portion 8a that holds the outer peripheral surface of the base end side of the original upper collar 2 in a housed state by pressing, and from the tip side A guide portion 8b that guides the proximal end portion of the upper collar 2 so as to gradually reduce the diameter toward the holding portion 8a is integrally provided. Such a holding member 8 can be provided integrally with the bottom plug 7 so as to form a male screw portion 8c and to be screwed into the cylindrical body 7a.

なお、前記保持部８ａ及び案内部８ｂが形成された保持部材８は、後述する長さ調節機構との関係で、軸方向の設置位置が特定されている。   The holding member 8 on which the holding portion 8a and the guide portion 8b are formed has an axial installation position specified in relation to a length adjusting mechanism described later.

前記元竿１の先端内面と元上竿２の外面には、元上竿２を元竿１に対して伸長状態と収縮状態に保持する長さ調節機構１０が設けられている。この長さ調節機構１０は、元上竿２の先端側外面に形成された継合領域２ａと、元上竿２を元竿１に収納した際、前記元上竿２の外面に形成された継合領域２ａと継合して元上竿２の周方向の回転を防止した状態で、元上竿２を固定、保持する回転防止部１１とを備えている。   A length adjusting mechanism 10 is provided on the inner surface of the front end of the main bar 1 and the outer surface of the upper bar 2 to hold the upper bar 2 in an expanded state and a contracted state with respect to the main bar 1. The length adjusting mechanism 10 is formed on the outer surface of the former upper collar 2 when the former upper collar 2 is housed in the joint area 2a formed on the outer surface of the front edge of the former upper collar 2 and the former upper collar 2. The anti-rotation part 11 which fixes and hold | maintains the upper collar 2 in the state which prevented the rotation of the circumferential direction of the former collar 2 by joining with the joining area | region 2a is provided.

この場合、回転防止部１１は、元竿１とは別体でリング状に形成されており、円筒部１１ａとフランジ部１１ｂとを備え、フランジ部１１ｂが元竿１の開口端面に当て付けられた状態で円筒部１１ａの外面が元竿１の先端内面に接着等によって取着される。回転防止部１１は、元上竿２が収納された際、継合領域２ａと継合して元上竿２の周方向の回転を防止する機能を備えており、好ましくは、元上竿２の表面硬度よりも軟質な素材によって形成されている。具体的には、前記元上竿２が、炭素繊維など、繊維強化樹脂（プリプレグシート）によって管状に成形されたものであれば、それよりも軟質な素材、例えば、ポリアミド、ＡＢＳ樹脂、ポリウレタン等の合成樹脂によって形成したり、合成ゴム、エラストマー等によって形成することが可能である。また、このような元上竿２の表面硬度よりも軟質な部分を、硬質な円筒部１１ａの内面に取着したものであっても良い。   In this case, the rotation preventing portion 11 is formed in a ring shape separately from the main shaft 1, and includes a cylindrical portion 11 a and a flange portion 11 b, and the flange portion 11 b is applied to the opening end surface of the main shaft 1. In this state, the outer surface of the cylindrical portion 11a is attached to the inner surface of the front end of the main shaft 1 by bonding or the like. The anti-rotation portion 11 has a function of preventing rotation of the former upper collar 2 in the circumferential direction by joining with the joining region 2a when the former upper collar 2 is stored. It is made of a material that is softer than the surface hardness. Specifically, if the said upper collar 2 is formed into a tubular shape by a fiber reinforced resin (prepreg sheet) such as carbon fiber, a softer material such as polyamide, ABS resin, polyurethane, etc. It is possible to form with a synthetic resin, or with synthetic rubber or elastomer. Further, a portion softer than the surface hardness of the original upper collar 2 may be attached to the inner surface of the hard cylindrical portion 11a.

また、前記円筒部１１ａの内面には、継合する元上竿２との関係で、周方向の摩擦力が高くなるように、回転を防止する手段として、例えば、周方向に沿って凸部１１ｃが連続的に形成されている。このような回転を防止する手段は、凸部１１ｃ以外にも、円筒部１１ａの内面を粗面化したり、エンボス加工すること等で形成しても良い。   Further, on the inner surface of the cylindrical portion 11a, for example, as a means for preventing rotation so as to increase the frictional force in the circumferential direction in relation to the former upper collar 2 to be joined, for example, a convex portion along the circumferential direction 11c is formed continuously. The means for preventing such rotation may be formed by roughening or embossing the inner surface of the cylindrical portion 11a in addition to the convex portion 11c.

また、前記元上竿２の外面に形成される継合領域２ａは、元上竿２を元竿１に収納した際に、回転防止部１１と継合する部分に膨出状に形成されている。このため、継合領域２ａは、例えば、元上竿２を、上記のように繊維強化樹脂によって管状に成形する際、所定の領域に補強シートを配置する等して、該当部分を肉厚状にすることで一体形成することが可能である。本実施形態では、肉厚状に形成した継合領域２ａに、周方向に所定間隔おいて軸長方向に延出する凹溝２ｃを形成しており、これにより、元上竿２を元竿１に収納した際に、図３（ｃ）に示すように、継合領域２ａの凹溝２ｃと前記回転防止部１１の内面に形成された凸部１１ｃが継合し、元上竿２は、元竿１に対して周方向に回転することが防止される。   Further, the joining region 2a formed on the outer surface of the former upper collar 2 is formed in a bulging shape at a portion where the former upper collar 2 is joined to the rotation preventing portion 11 when the former upper collar 2 is stored in the former collar 1. Yes. For this reason, the joining area | region 2a, for example, arrange | positions a reinforcement sheet | seat in a predetermined | prescribed area | region when shape | molding the former upper collar 2 into a tubular shape with a fiber reinforced resin as mentioned above, and a corresponding part is thick-shaped. It is possible to form integrally. In the present embodiment, the groove 2c extending in the axial length direction at a predetermined interval in the circumferential direction is formed in the joining region 2a formed in a thick shape. 3, as shown in FIG. 3 (c), the concave groove 2 c of the joining region 2 a and the convex part 11 c formed on the inner surface of the rotation preventing part 11 are joined together, Rotation in the circumferential direction with respect to the main shaft 1 is prevented.

ここで、前記保持部８ａ及び案内部８ｂが形成された保持部材８と、長さ調節機構１０の軸方向の設置関係について説明する。   Here, the installation relationship in the axial direction of the holding member 8 formed with the holding portion 8a and the guide portion 8b and the length adjusting mechanism 10 will be described.

前記元上竿２を、元竿１に収納する際、図２（ｂ）に示すように、まず、元上竿２の基端部（基端縁２ｄ）が案内部８ｂに案内され始め、基端部が軸方向に所定長さを有する保持部８ａに移行するまでは、前記元上竿２の継合領域２ａは、回転防止部１１に継合することはない。そして、元上竿２を更に収納した段階で、元上竿２の基端部（基端縁２ｄ）は、案内部８ｂから保持部８ａに移行し、保持部８ａによって外周面が圧着されて、元上竿２はガタ付いたり周方向に回転することが抑制された状態となる。このように元上竿２の基端部が保持部８ａに移行して元上竿２のガタ付きや回転が抑制された後、図３（ｂ）に示すように、元上竿２の継合領域２ａが回転防止部１１に継合するように位置決めが成される。   When the upper arm 2 is stored in the upper arm 1, as shown in FIG. 2B, first, the base end portion (base end edge 2d) of the upper arm 2 starts to be guided to the guide portion 8b. Until the base end portion moves to the holding portion 8a having a predetermined length in the axial direction, the joining region 2a of the former upper collar 2 is not joined to the rotation preventing portion 11. At the stage where the upper collar 2 is further accommodated, the base end (base edge 2d) of the upper collar 2 moves from the guide portion 8b to the holding portion 8a, and the outer peripheral surface is crimped by the holding portion 8a. The former saddle 2 is in a state where it is prevented from rattling or rotating in the circumferential direction. Thus, after the base end portion of the upper collar 2 is moved to the holding portion 8a and the backlash and rotation of the upper collar 2 are suppressed, as shown in FIG. Positioning is performed so that the joint region 2a is joined to the rotation prevention unit 11.

すなわち、元上竿２の収納操作時において、元上竿２の基端部が案内部８ｂに沿ってガイドされることでガタ付きや周方向の回転が次第に抑制され、その後、保持部８ａに保持されて周方向への回転が抑制された状態になってから、前記元上竿２の継合領域２ａが回転防止部１１に継合するように、前記保持部材８と、長さ調節機構１０は、軸方向で位置決め設置されている。   That is, at the time of storing operation of the upper collar 2, the base end of the upper collar 2 is guided along the guide portion 8 b, so that rattling and circumferential rotation are gradually suppressed, and then the holding portion 8 a The holding member 8 and the length adjusting mechanism are connected so that the joining region 2a of the upper collar 2 is joined to the rotation preventing portion 11 after being held and prevented from rotating in the circumferential direction. 10 is positioned and installed in the axial direction.

以上のように構成された釣竿によれば、長さ調節機構１０によって、元上竿２を元竿１に対して収縮・伸長することで、全体として長さ調節が可能となる。この場合、元上竿２を元竿１に収納すると、上記のように、まず、元上竿２の基端部が元竿１の基端側に設けられた案内部８ｂに案内されることから、挿入するに従い、ガタ付きや周方向の回転が次第に抑制されるようになる。そして、このような状態になって更に元上竿２の基端部が保持部８ａに保持された後、元上竿２の継合領域２ａが回転防止部１１に継合するため、元上竿２の挿入操作時において元上竿２がガタ付いたり、周方向に回転することはなく、安定した状態で収納操作が行える。   According to the fishing rod configured as described above, the length can be adjusted as a whole by contracting and extending the upper rod 2 with respect to the main rod 1 by the length adjusting mechanism 10. In this case, when the upper arm 2 is housed in the main arm 1, the base end portion of the upper arm 2 is first guided to the guide portion 8b provided on the base end side of the main shaft 1 as described above. Therefore, as it is inserted, rattling and rotation in the circumferential direction are gradually suppressed. And since it becomes in such a state and the base end part of the former upper collar 2 is hold | maintained at the holding | maintenance part 8a, since the joining area | region 2a of the former upper collar 2 is joined to the rotation prevention part 11, During the insertion operation of the heel 2, the upper heel 2 does not rattle or rotate in the circumferential direction, and the storage operation can be performed in a stable state.

このように、元上竿２の収納時において、その後端部が元竿１に対してガイドされながら軸方向に移動し、ガタ付いたり周方向に回転することがなくなってから、回転防止部１１に形成された周方向の回転を防止する凸部１１ｃに対して継合領域２ａの凹溝２ｃの嵌め合わせがなされるため、収納操作を容易に行えるようになり、元上竿を元竿に収納する際の操作性が良好になる。   As described above, when the upper collar 2 is stored, the rear end moves in the axial direction while being guided with respect to the former collar 1, and does not rattle or rotate in the circumferential direction. Since the concave groove 2c of the joining region 2a is fitted to the convex portion 11c that prevents the circumferential rotation formed in the container, the storing operation can be easily performed, and the upper arm is used as the main arm. Operability when storing is improved.

以上、本発明の実施形態について説明したが、本発明は、上記した実施形態の形状に限定されることはなく、種々変形することが可能である。   As mentioned above, although embodiment of this invention was described, this invention is not limited to the shape of above-described embodiment, It can change variously.

本発明に係る釣竿は、上記した中通し式以外にも、外ガイド式であっても良いし、渓流竿のようにリールを装着しない釣竿に適用しても良い。また、その竿節数についても適宜変更することが可能であり、長さ調節が成される部分となる元竿と元上竿との関係は、釣竿の中間節部分であっても良い。   The fishing rod according to the present invention may be an outer guide type other than the above-described centering type, or may be applied to a fishing rod that is not mounted with a reel, such as a mountain stream rod. Further, the number of rods can be changed as appropriate, and the relationship between the main rod and the upper rod which is a portion where the length is adjusted may be an intermediate node portion of the fishing rod.

また、上記した長さ調節機構１０は、回転防止部１１が継合領域２ａと継合して、周方向の回転が抑制された状態で固定される構成であれば、具体的な表面状態については適宜変形することが可能である。また、元上竿２に形成される継合領域２ａについては、管状体を成形した後に、別体として膨出部を取着する構成であっても良く、その形成される位置についても適宜変形することが可能である。   Moreover, if the above-mentioned length adjustment mechanism 10 is a structure fixed by the rotation prevention part 11 joining with the joining area | region 2a and the rotation of the circumferential direction being suppressed, about a specific surface state Can be appropriately modified. Moreover, about the joint area | region 2a formed in the former collar 2, after a tubular body is shape | molded, the structure which attaches a bulging part as another body may be sufficient, and it changes suitably also about the position formed. Is possible.

また、保持部材８については、元上竿２の収納操作時において、まず元上竿２の基端部を案内部８ｂで案内し、その後、元上竿２の軸を中心としたガタ付きや、周方向の回転が抑制された段階で、元上竿２の基端部を保持部８ａで保持できる構成であれば種々変形することが可能である。さらに、保持部材８は、上述した実施形態とは逆に、元上竿２の基端側の内面を保持するような構成であっても良い。このような保持部材の案内部は、基端側に移行するに連れて次第に拡径する円錘状に形成され、保持部は、元上竿２の内周面に圧着する円筒状（円柱状）に形成される。   For the holding member 8, the base end portion of the upper upper collar 2 is first guided by the guide portion 8 b during the storage operation of the upper upper collar 2, and thereafter, Various modifications can be made as long as the base end portion of the upper collar 2 can be held by the holding portion 8a when the circumferential rotation is suppressed. Furthermore, the structure which hold | maintains the inner surface of the base end side of the upper collar 2 may be sufficient as the holding member 8 contrary to embodiment mentioned above. The guide portion of such a holding member is formed in a conical shape that gradually increases in diameter as it moves to the proximal end side, and the holding portion is a cylindrical shape (columnar shape) that is pressure-bonded to the inner peripheral surface of the upper collar 2. ).
