Description

この発明は、例えば磯釣り等に使用される玉の柄に用いるのに好適する竿杆合わせ構造に関する。 The present invention relates to a kite-matching structure suitable for use in, for example, a ball handle used for kite fishing or the like.

一般に、釣り形態としては、防波堤の上や足場の高い磯より、キャスティングして所望の魚を釣る方法が知られている。この釣り形態は、釣り場において、魚がかかると、釣り人が釣竿と共に、先端に玉網を配した玉の柄を手に持って、玉の柄を伸長させて、その玉網で釣り上げた魚をすくい手元まで引き上げられる。このような玉の柄は、複数の杆が伸縮自在に継合されており、使用時、その複数の杆を伸長させて使用することで、機敏に対応できる取扱い操作性が要請される。 In general, as a fishing form, a method is known in which a desired fish is caught by casting from a breakwater or a high anchorage. In this fishing mode, when a fish is caught at a fishing spot, the fisherman holds a ball handle with a ball net at the tip together with the fishing rod, and extends the ball handle, and the fish caught by the ball net. Can be raised to the scoop. In such a ball pattern, a plurality of heels are stretchably joined, and when used, the handling operability capable of being agile is required by extending the plurality of heels.

そのため、このような玉の柄においては、その竿杆合わせ構造として、例えば伸縮自在に継合される複数の竿杆の前側竿杆の内側継合部に軸長方向の強化繊維量を少なくした薄肉部を形成し、この薄肉部の後端に肉盛り部を形成して、この内側継合部を後側竿杆に嵌合させることにより、継合部位の剛性を抑えた継合を行うようにして取扱い操作性を高めるように構成したものがある（例えば、特許文献１参照。）。 Therefore, in such a ball pattern, the amount of reinforcing fibers in the axial length direction is reduced, for example, in the inner joint portion of the front side collars of a plurality of collars that are stretchably joined as the joint structure. Forming a thin-walled part, forming a built-up part at the rear end of the thin-walled part, and fitting the inner joint part to the rear side heel, thereby performing joint with reduced rigidity of the joint part In this way, there is one configured to improve handling operability (see, for example, Patent Document 1).

また、竿杆合わせ構造としては、大径ロッド部材に受口部を設け、小径ロッド部材に差込口を設けて、この受口部と差込口の少なくとも一方の周部に繊維配向が軸長方向に対して傾斜した強化繊維層を設けることにより、塑性曲がり、剛性の低下を防止するようにして安定した継合を可能に構成したものもある（例えば、特許文献２参照。）。
特開平１１−２６６７４７号公報特開２００２−１７２０９号公報 In addition, as the fitting structure, a receiving portion is provided in the large-diameter rod member, and an insertion port is provided in the small-diameter rod member. Some are configured to enable stable joining by providing a reinforcing fiber layer inclined with respect to the longitudinal direction so as to prevent plastic bending and a decrease in rigidity (for example, see Patent Document 2).
JP-A-11-266747 JP 2002-17209 A

しかしながら、上記前者の竿杆合わせ構造では、剛性を抑えて取り扱い操作性の向上を図っている構成のために、全体的な剛性が低くなり、所謂、パワー不足となる。 However, in the former fitting structure, since the rigidity is suppressed and the handling operability is improved, the overall rigidity is lowered, and so-called power shortage occurs.

また、後者の竿杆合わせ構造では、塑性曲がりや剛性の低下が防止されて高精度な継合状態が確保されるものの、同様に竿杆を伸長させる際に、継合部位に大きな負荷が加わると、固着状態となる虞を有する。 Moreover, in the latter joining structure, although a plastic bending and a fall of rigidity are prevented and a highly accurate joining state is ensured, when a coffin is extended similarly, a big load is added to a joining part. And there is a possibility of becoming a fixed state.

そして、このような竿杆合わせ構造においては、上記伸長状態における継合部位の固着防止の他、その竿杆取り扱い性を考慮した場合、竿杆操作に支障を来たさないように継合部位の回転を規制することが要求される。 In addition, in such a joining structure, in addition to preventing the joining part from sticking in the extended state, when considering the handling ability of the joining part, the joining part is provided so as not to hinder the scissor operation. It is required to regulate the rotation of the.

この発明は上記の事情に鑑みてなされたもので、堅牢にして安定した伸縮操作を実現したうえで、継合部位の固着防止と共に、回転防止を実現して、竿杆取り扱い性の向上を図り得るようにした竿杆合わせ構造を提供することを目的とする。 The present invention has been made in view of the above circumstances, and after realizing a robust and stable expansion and contraction operation, in addition to preventing the joining portion from being fixed, it also prevents rotation, thereby improving the handleability. It is an object of the present invention to provide a mating structure that can be obtained.

この発明は、先端に被取付体が装着される複数の竿杆を伸縮自在に継合してなる竿杆合わせ構造において、前記竿杆の先側継合部の内壁に、元側に回転規制部が形成された第１の突出部を設け、且つ、前記竿杆と継合する先側竿杆の元側継合部の外壁に、前記第１の突出部と軸方向で係止される先側に回転規制部が形成された第２の突出部を設け、前記竿杆に対して前記先側竿杆が伸長されて、前記第１の突出部が前記先側竿杆の第２の突出部に軸方向で係止されると、互いの回転規制部が係合して回転が規制されると共に、前記第１の突出部と前記竿杆の外壁、前記第２の突出部と前記元側竿杆の内壁との間に間隙を有するように構成した。 The present invention relates to a saddle stitching structure in which a plurality of collars to which attachments are attached at their tips are stretchably joined, and on the inner wall of the front joint part of the collar, the rotation is restricted to the original side. A first protrusion formed with a portion is provided, and is locked in an axial direction with the first protrusion on an outer wall of a former side joining portion of a front side collar that is joined to the collar. A second protrusion having a rotation restricting portion formed on the front side is provided, the front side hook is extended with respect to the hook, and the first protrusion is a second of the front side hook. When locked to the protruding portion in the axial direction, the rotation restricting portions engage with each other to restrict the rotation, and the first protruding portion, the outer wall of the bag, the second protruding portion, and the It comprised so that it might have a clearance gap with the inner wall of the former side wall.

上記構成によれば、複数の竿杆は、重力や慣性力により伸長・縮小され、その伸長状態において、第１の突出部及び第２の突出部が、軸方向で係止された状態で、それらに対向する外壁及び内壁との間に間隙を有している。これにより、竿杆が伸長されて継合部における第２の突出部が第１の突出部に当接されると、相互の回転規制部が係合されて、相互間の回転が防止されると共に、その第１及び第２の突出部と竿杆の外壁、内壁との間に存在する間隙により、相互間の固着が防止される。従って、竿杆の安定した高精度な伸縮操作が可能となると共に、伸長状態における回転が規制されるため、竿杆取り扱い性の向上が図れる。 According to the above configuration, the plurality of scissors are expanded and contracted by gravity and inertial force, and in the extended state, the first protrusion and the second protrusion are locked in the axial direction. There is a gap between the outer wall and the inner wall facing each other. As a result, when the collar is extended and the second projecting portion in the joining portion is brought into contact with the first projecting portion, the mutual rotation restricting portions are engaged, and mutual rotation is prevented. At the same time, the gap between the first and second protrusions and the outer and inner walls of the bag is prevented from sticking to each other. Therefore, stable and highly accurate expansion / contraction operation of the heel can be performed, and rotation in the extended state is restricted, so that heel handling can be improved.

この発明によれば、堅牢にして安定した伸縮操作を実現したうえで、継合部位の固着防止と共に、回転防止を実現して、竿杆取り扱い性の向上を図り得るようにした竿杆合わせ構造を提供することができる。 According to the present invention, after realizing a robust and stable expansion and contraction operation, it is possible to prevent the rotation of the joint portion and prevent rotation, and to improve the handle handling ability. Can be provided.

以下、この発明の実施の形態について、図面を参照して詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図１は、この発明の一実施の形態に係る竿杆合わせ構造を適用した玉の柄の外観構成を示すもので、柄本体１０は、例えば第１乃至第６の竿杆１１〜１６が伸縮自在に継合される振り出し構造に形成される。これら第１乃至第６の竿杆１１〜１６は、例えば炭素繊維等の強化繊維にエポキシ樹脂等の合成樹脂を含浸した繊維強化プリプレグ（以下の説明では、単にプリプレグと称する）を周方向、軸方向あるいは軸線に対して適宜角度の傾斜した偏向方向に引き揃えて巻回した中空構造に形成され、その第１の竿杆１１の先端には、被取付体、例えば玉枠に網が装着された玉網１７が着脱自在に取付けられる。 FIG. 1 shows an external configuration of a ball handle to which a knot-matching structure according to an embodiment of the present invention is applied. A handle body 10 has, for example, first to sixth hooks 11 to 16 that extend and contract. It is formed in a swing-out structure that can be joined together freely. These first to sixth ridges 11 to 16 are, for example, a fiber reinforced prepreg obtained by impregnating a reinforced fiber such as a carbon fiber with a synthetic resin such as an epoxy resin (hereinafter simply referred to as a prepreg) in the circumferential direction, It is formed in a hollow structure that is wound by being aligned in a deflecting direction inclined at an appropriate angle with respect to the direction or axis, and a net is attached to an attached body, for example, a ball frame, at the tip of the first ridge 11. A tag net 17 is detachably attached.

第１乃至第６の竿杆１１〜１６は、その先側及び元側継合部Ａにおいて略同様にこの発明の特徴とする竿杆合わせ構造により伸縮自在に継合される。この竿杆合わせ構造が構成される各継合部Ａは、略同様に竿杆先端側及び後端側に例えば寸法Ｌ（図２参照）に構成され、その伸長状態で、軸方向で位置決めされた状態で、その先端部が先側竿杆の外壁及び前記竿杆の内壁との間に間隙を有している。 The 1st thru | or 6th collars 11-16 are joined in the front side and the former side joining part A so that expansion-contraction is possible substantially by the joining structure characterized by this invention. Each joint portion A constituting the butt-joining structure is configured in a similar manner, for example, with a dimension L (see FIG. 2) on the heel tip side and rear end side, and is positioned in the axial direction in its extended state. In this state, the front end portion has a gap between the outer wall of the front heel and the inner wall of the heel.

ここで、上記第１乃至第６の竿杆１１〜１６の先側及び元側継合部Ａは、略同様に構成されることで、説明の便宜上、第２及び第３の竿杆１２，１３の継合部Ａ（第２の竿杆１２の元側、言い換えると第３の竿杆１３の先側）を代表して詳細に説明し、その他の継合部Ａの説明を省略する。 Here, the front side and the former side joining portion A of the first to sixth ridges 11 to 16 are configured in substantially the same manner, and for convenience of explanation, the second and third ridges 12, 13 joint portions A (the original side of the second ridge 12, in other words, the front side of the third ridge 13) will be described in detail, and the description of the other joint portions A will be omitted.

即ち、第２の竿杆１２には、その外壁の後端部に、図３に示すように例えば強化繊維を用いたプリプレグを巻回してなる第２の突出部１２１が設けられる。この第２の突出部１２１は、上記第３の竿杆１３の先端側内壁に対して所定の間隙、例えば０．０２〜０．３０ｍｍのクリアランスを有するように突出して形成され、その先側先端部の周壁に回転規制部を構成する、例えば先側方向に縮径するように傾斜した複数の傾斜部１２２が周方向に所定の間隔を有して形成される。この傾斜部１２２は、第２の突出部１２１の周壁に先側（竿先）より元側（元竿）方向に先細りに形成される。 That is, the second ridge 12 is provided with a second protrusion 121 formed by winding a prepreg using, for example, a reinforcing fiber, as shown in FIG. The second projecting portion 121 is formed so as to project with a predetermined gap, for example, a clearance of 0.02 to 0.30 mm, with respect to the inner wall on the front end side of the third flange 13, and its front end A plurality of inclined portions 122 that form a rotation restricting portion on the peripheral wall of the portion, for example, are inclined so as to be reduced in diameter toward the front side, are formed with a predetermined interval in the circumferential direction. The inclined portion 122 is formed on the peripheral wall of the second projecting portion 121 so as to taper in the original side (general heel) direction from the front side (tip).

他方、第３の竿杆１３には、図４に示すようにその先側に内径が略ストレート形状のストレート部１３１が設けられ、このストレート部１３１の先端には、強化繊維を用いたプリプレグを巻回してなるリング状の第１の突出部１３２が、上記第２の竿杆１２の第２の突出部１２１に対応して形成される。この第１の突出部１３２は、上記第２の竿杆１２の外壁に対して０．３０〜０．７０ｍｍのクリアランスを有するように又、肉厚は０．３〜１．０ｍｍ好ましくは０．４５〜０．９ｍｍの寸法に形成される。そして、この第１の突出部１３２の後端側（元側）には、傾斜した複数の凸部１３３が、上記第２の竿杆１２の第２の突出部１２１の傾斜部１２２に対応して周方向に所定の間隔を有して設けられる。この複数の凸部１３３は、その頂部が元側方向に縮径するように傾斜され、且つ、先側より元側方向に先細りに形成される。 On the other hand, as shown in FIG. 4, the third flange 13 is provided with a straight portion 131 having a substantially straight inner diameter on the front side thereof, and a prepreg using reinforcing fibers is attached to the tip of the straight portion 131. A ring-shaped first protrusion 132 formed by winding is formed corresponding to the second protrusion 121 of the second flange 12. The first protrusion 132 has a clearance of 0.30 to 0.70 mm with respect to the outer wall of the second flange 12, and the wall thickness is 0.3 to 1.0 mm, preferably 0.00. It is formed in the dimension of 45-0.9mm. Then, on the rear end side (original side) of the first protrusion 132, a plurality of inclined protrusions 133 correspond to the inclined part 122 of the second protrusion 121 of the second collar 12. And provided at a predetermined interval in the circumferential direction. The plurality of convex portions 133 are inclined such that the top portions thereof are reduced in diameter in the original direction, and are formed to be tapered in the original direction from the front side.

これにより、第３の竿杆１３は、第２の竿杆１２が伸長されると、その第１の突出部１３２が第２の竿杆１２の第２の突出部１２１に対して軸方向において安定して係止されると共に、その先端部が第２の竿杆１２の外壁と所定の間隙（例えば、０．３０〜０．７０ｍｍ）を有して対設されて固着が防止される。この際、第３の竿杆１３は、その第１の突出部１３２の複数の凸部１３３が第２の竿杆１２の第２の突出部１２１の複数の傾斜部１２２に当接されて係合され、これら凸部１３３及び傾斜部１２２の作用により第２の竿杆１２との間の回転が規制される。 As a result, when the second rod 12 is extended, the third rod 13 has its first protrusion 132 in the axial direction with respect to the second protrusion 121 of the second rod 12. While being locked stably, the front-end | tip part has a predetermined gap | interval (for example, 0.30-0.70 mm) with the outer wall of the 2nd collar 12, and adhering is prevented. At this time, the third flange 13 is engaged with the plurality of convex portions 133 of the first protrusion 132 in contact with the plurality of inclined portions 122 of the second protrusion 121 of the second flange 12. The rotation between the second flange 12 is restricted by the action of the convex portion 133 and the inclined portion 122.

上記第２の突出部１２１の傾斜部１２２及び第１の突出部１３２の凸部１３３は、同数を配することなく、少なくとも一方に一個を設けて、他方に複数個を設けて構成するようにしてもよいし、あるいは、双方とも一個を配するように構成してもよい。 The inclined portion 122 of the second projecting portion 121 and the convex portion 133 of the first projecting portion 132 are not provided in the same number, but at least one is provided and the other is provided with a plurality. Alternatively, both may be arranged as one.

例えば、少なくとも一方に一個を設けて、他方に複数個を設けて構成した場合には、第２及び第３の竿杆１２，１３の伸長途中において、相互間を回転させて、一方の傾斜部１２２あるいは凸部１３３を他方の凸部１３３あるいは傾斜部１２２のいずれかに選択的に係合させる如く変更させることで、相互間の回転角を変更させることが可能となる。また、傾斜部１２２は、凸部１３３の数より多く設けた方が係合させ易い。そして、これら傾斜部１２２及び凸部１３３は、溝状に設けるようにしてもよい。 For example, in the case where at least one is provided and a plurality is provided on the other, the second and third rods 12 and 13 are rotated in the middle of each other, and one inclined portion is rotated. It is possible to change the rotation angle between the two by changing the 122 or the protrusion 133 so as to be selectively engaged with either the other protrusion 133 or the inclined part 122. In addition, it is easier to engage the inclined portion 122 if it is provided more than the number of the convex portions 133. And these inclination part 122 and convex part 133 may be made to provide in groove shape.

ここで、第２の竿杆１２の第２の突出部１２１と第３の竿杆１３の内壁とのクリアランスは、第３の竿杆１３の第１の突出部１３２と第２の竿杆１２の外壁とのクリアランスと同等もしくは小さく、言い換えると、第１の突出部１３２のクリアランスを第２の突出部１２１のクリアランスと同等もしくは大きく設定することにより、相互間の摺り防止が図れて安定した伸縮動作が可能となり、より好ましい。特に、竿杆先端部に荷重が掛かった状態で、摺動する時に、第１の突出部１３２と第２の竿杆１２の外壁が滑り難い。また、この第２の突出部１２１のクリアランスは、小さくすると、所謂、節を最後まで伸長しない状態でも、例えば玉の柄としての使用が可能となり、長さ調整機能を奏することも可能となる。 Here, the clearance between the second protrusion 121 of the second flange 12 and the inner wall of the third flange 13 is the same as the first protrusion 132 of the third flange 13 and the second flange 12. By setting the clearance of the first protrusion 132 to be equal to or larger than the clearance of the second protrusion 121, it is possible to prevent slippage between the two and the stable expansion and contraction. Operation is possible and more preferable. In particular, when sliding in a state where a load is applied to the heel tip, the first protrusion 132 and the outer wall of the second ridge 12 are difficult to slide. Further, if the clearance of the second projecting portion 121 is reduced, it can be used as a ball handle, for example, even when the so-called knot is not extended to the end, and a length adjusting function can be achieved.

なお、上記第２の突出部１２１は、第３の竿杆１３の内壁との間のクリアランスが０．３ｍｍより大きくとると、所謂「がた」が大きくなるために、伸縮操作性が低下されることが確認されている。 When the clearance between the second projecting portion 121 and the inner wall of the third flange 13 is greater than 0.3 mm, so-called “ra” becomes large, and the telescopic operability is reduced. It has been confirmed that

また、上記第２の竿杆１２の第２の突出部１２１及び第３の竿杆１３の第１の突出部１３２は、その互いに当接される面が略直角形状もしくは、竿先方向に傾斜した傾斜形状またはＲ状に形成してもよい。この場合、竿先方向に傾斜させた場合には、第２の竿杆１２が第３の竿杆１３内から摺動する際、スムーズな移動が可能となるうえ、第２の突出部１２１が第１の突出部１３２に当接する際の衝撃が弱められると共に、相互間に若干の嵌合力が付与されて、これによっても伸長時における回転防止が図れる。 In addition, the second protrusion 121 of the second flange 12 and the first protrusion 132 of the third flange 13 are substantially perpendicular to each other or inclined in the tip direction. It may be formed in an inclined shape or an R shape. In this case, when inclined in the tip direction, when the second rod 12 slides from within the third rod 13, smooth movement is possible and the second protrusion 121 is The impact at the time of coming into contact with the first protrusion 132 is weakened, and a slight fitting force is applied between them, thereby preventing rotation at the time of extension.

上記第３の竿杆１３は、ストレート部１３１より元側の内径が、ストレートから０．８/１０００の範囲の緩テーパ形状に形成される。ストレートに形成した場合には、第２の竿杆１２の伸長及び縮小時に移動速度が抑えられる。そして、内径を緩テーパ形状に形成した場合には、第２の竿杆１２の出入り速度を高めることが可能となり、迅速な出入り操作が可能となる。 The third flange 13 is formed in a gentle taper shape in which the inner diameter on the original side from the straight portion 131 is in the range of 0.8 / 1000 from the straight. When it is formed straight, the moving speed is suppressed when the second ridge 12 is expanded and contracted. When the inner diameter is formed in a gently tapered shape, the entry / exit speed of the second rod 12 can be increased, and a quick entry / exit operation can be performed.

ここで、上記第２及び第３の竿杆１２，１３は、その第２の突出部１２１を含む継合面及びその第１の突出部１３２を含む継合面に対して滑利制御部材、例えばワックス等の滑り材を塗布して、相互間の摺動特性を高められるように構成したり、逆に、相互の継合面に、植毛等の摩擦抵抗部材を設けて摺動抵抗を高めるように構成して、所望の滑りを得るようにすることで、さらに、竿杆取り扱い性の向上が図れる。 Here, the second and third flanges 12 and 13 have a slippage control member with respect to the joining surface including the second projecting portion 121 and the joining surface including the first projecting portion 132, For example, a sliding material such as wax can be applied to improve the sliding characteristics between them, or conversely, friction resistance members such as flocking are provided on the mutual joining surfaces to increase the sliding resistance. By configuring as described above and obtaining a desired slip, it is possible to further improve the handleability.

上記構成により、第１乃至第６の竿杆１１〜１６は、例えば縮小状態から先端部が下向きに向けられると、その各継合部Ａにおいて重力や慣性力により順に引き出されて伸長される。具体的には、第２の竿杆１２は、第３の竿杆１３に対して引き出されて伸長されると、その第２の突出部１２１が第３の竿杆１３の第１の突出部１３２に接近し、伸長が完了した状態で、当接されて位置規制されると共に、その傾斜部１２２に対して第３の竿杆１３の第１の突出部１３２の凸部１３３が係合されて相互間の回転が規制される。ここで、第２の竿杆１２の第２の突出部１２１及び第３の竿杆１３の第１の突出部１３２は、それぞれ第３の竿杆１３の内壁及び第２の竿杆１２の外壁に対して所定の間隙（クリアランス）があることで、所謂、固着が防止される。 With the above-described configuration, for example, when the distal end portion is directed downward from the contracted state, the first to sixth ridges 11 to 16 are sequentially pulled out and extended by gravity and inertial force at each joint portion A. Specifically, when the second ridge 12 is pulled out and extended with respect to the third ridge 13, the second protrusion 121 becomes the first protrusion of the third ridge 13. In a state in which it has approached 132 and has been extended, the position of the first protrusion 132 of the third collar 13 is engaged with the inclined portion 122 by being brought into contact with the inclined portion 122. Therefore, the rotation between each other is restricted. Here, the second protrusion 121 of the second flange 12 and the first protrusion 132 of the third flange 13 are the inner wall of the third flange 13 and the outer wall of the second flange 12, respectively. On the other hand, the presence of a predetermined gap (clearance) prevents so-called sticking.

ここで、第１乃至第６の竿杆１１〜１６は、上述した第２及び第３の竿杆１２，１３の継合部Ａ以外も同様にクリアランスを持って伸長されて固着が防止されると共に、相互間の回転が規制される。これにより、これら第１乃至第６の竿杆１１〜１６は、その伸長状態において、各継合部Ａを含む竿杆全体としてのバランスを得ることができる。 Here, the 1st thru | or 6th collars 11-16 are similarly extended with clearance other than the joint part A of the 2nd and 3rd collars 12 and 13 mentioned above, and adhesion is prevented. At the same time, the mutual rotation is restricted. Thereby, these 1st thru | or 6th collars 11-16 can obtain the balance as the whole collar including each joining part A in the expansion | extension state.

また、上記第１乃至第６の竿杆１１〜１６は、伸長状態から縮小収納する場合、各竿杆における継合部をその第１及び第２の突出部１３２，１２１の先端のクリアランスにより、継合部Ａを差込む如く操作することにより、各部が縮小されて容易に収納される。この際、第２の突出部１２１の傾斜部１２２は、第１の突出部１３２の凸部１３３に案内され摺動されて縮小を許容する。 In addition, when the first to sixth ridges 11 to 16 are housed in a reduced state from the extended state, the joint portion of each ridge is defined by the clearance of the tips of the first and second projecting portions 132 and 121. By operating the joint part A so as to be inserted, each part is reduced and easily accommodated. At this time, the inclined portion 122 of the second projecting portion 121 is guided and slid by the convex portion 133 of the first projecting portion 132 to allow reduction.

このように、上記竿杆合わせ構造は、第３の竿杆１３の内壁に、第２の竿杆１２の外壁と間隙を有して対設される回転規制用の凸部１３３を有した第１の突出部１３２を設け、第２の竿杆１２の外壁に、第３の竿杆１３の内壁と間隙を有して対設され、上記第１の突出部１３２と軸方向で係止される回転規制用の傾斜部１２２を有した第２の突出部１２１を設けて、第２及び第３の竿杆１２，１３が伸長されると、互いの第１及び第２の突出部１３２、１２１が軸方向で係止されると共に、該第１及び第２の突出部１３２，１２１の凸部１３３及び傾斜部１２２が係合されて回転が規制され、この回転が規制された状態で、第３の竿杆１３の第１の突出部１３２が第２の竿杆１２の外壁との間、及び第２の竿杆１２の第２の突出部１２１が第３の竿杆１３の内壁との間に間隙を有するように構成した。 In this way, the above-described flange-matching structure includes the first rib 133 having a rotation restricting convex portion 133 that is opposed to the outer wall of the second rod 12 with a gap. 1 projecting portion 132 is provided, and is opposed to the outer wall of the second collar 12 with a gap from the inner wall of the third collar 13, and is locked in the axial direction with the first projecting portion 132.
