FIG. 4 is a cross-sectional view of the pipe body of the extension pipe of the first embodiment cut in a direction orthogonal to the axis, and FIG. 5 is a diagram illustrating the laminated structure of the pipe body of the extension pipe of the first embodiment.
As shown in FIGS. 4 and 5, the pipe body 40 is made of dry carbon in which a plurality of cylindrical carbon fiber layers 41 are laminated. In the case of the first embodiment, the multiple laminated cylindrical carbon fiber layers 41 are composed of a first cylindrical carbon fiber layer 41a, a second cylindrical carbon fiber layer 41b, and a third cylindrical carbon fiber layer 41c laminated in this order from the inside. become. A resin coating layer 42 is laminated as the outermost layer on the outer peripheral surface of the third cylindrical carbon fiber layer 41c. Then, it is processed as dry carbon. Dry carbon is molded in a kiln that can be pressurized using a pressure-resistant device capable of increasing the internal pressure.

図５に示すように、第１筒形炭素繊維層４１ａは、管長手方向と平行に延びる複数の炭素繊維を有する１方向炭素繊維シートからなる。
第２筒形炭素繊維層４１ｂおよび第３筒形炭素繊維層４１ｃは、複数の炭素繊維の経糸および緯糸を有する２方向炭素繊維シートからなる。
１方向炭素繊維シートおよび２方向炭素繊維シートとしては、炭素繊維間に予め樹脂（例えば、エポキシ樹脂）が含浸された市販のプリプレグシートを用いることができる。なお、複数の炭素繊維は、経糸および緯糸以外に、斜め方向のようにクロスした糸状で構成することができる。また、クロスしたものや経糸および緯糸などの組合せを自由に組み替えてもよい。 As shown in FIG. 5, the first tubular carbon fiber layer 41a is made of a unidirectional carbon fiber sheet having a plurality of carbon fibers extending parallel to the longitudinal direction of the pipe.
The second tubular carbon fiber layer 41b and the third tubular carbon fiber layer 41c are made of bidirectional carbon fiber sheets having a plurality of warp and weft yarns of carbon fibers.
As the unidirectional carbon fiber sheet and the bidirectional carbon fiber sheet, commercially available prepreg sheets in which resin (for example, epoxy resin) is preliminarily impregnated between carbon fibers can be used. In addition to the warp and weft, the plurality of carbon fibers can be formed in a crossed filament form in an oblique direction. Also, the combination of crossed yarns, warp yarns and weft yarns may be freely rearranged.

パイプ本体４０は、市販のプリプレグシートを用いて第１～第３筒形炭素繊維層４１ａ、４１ｂ、４１ｃを１層ずつ型を用いた公知の方法によって成形し積層することによって製造することができる。例えば、金属棒のような軸棒に巻き付けていく方法がある。
また、形成後のパイプ本体４０の両端部の各開口端縁の対向位置には、第１および第２接続管部５０、６０との連結位置を位置決めするための切欠き部４３、４４が切削によって形成されている。なお、本実施形態の場合、パイプ本体４０の第１接続管部５０と連結される一端４０ａ側の切欠き部４３は、第２接続管部６０と連結される他端４０ｂ側の切欠き部４４よりも大きく形成されている。 The pipe body 40 can be manufactured by forming and laminating the first to third cylindrical carbon fiber layers 41a, 41b, and 41c one by one using a commercially available prepreg sheet by a known method using a mold. . For example, there is a method of winding around a shaft such as a metal rod.
In addition, notches 43 and 44 for positioning connection positions with the first and second connecting pipe portions 50 and 60 are cut at the opposing positions of the opening edges of both ends of the pipe body 40 after formation. formed by In the case of this embodiment, the notch 43 on the one end 40a side of the pipe body 40 connected to the first connecting pipe portion 50 is the notch portion on the other end 40b side connected to the second connecting pipe portion 60. It is formed larger than 44.

パイプ本体４０において、第１筒形炭素繊維層４１ａの厚みＴ１は約０．１ｍｍであり、第２および第３筒形炭素繊維層４１ｂ、４１ｃの厚みＴ２、Ｔ３はそれぞれ約０．２ｍｍであり、樹脂コーティング層４２の厚みＴ４は約０．１ｍｍであり、全体的な厚みＴ５は約０．６ｍｍである。なお、第１～第３筒形炭素繊維層４１ａ、４１ｂ、４１ｃの厚みは、それらの形成時に用いた１方向および２方向炭素繊維シートの厚みに由来する。なお、それぞれの厚み（Ｔ１、Ｔ２、Ｔ３、Ｔ４）は上記に限定されるものではない。 In the pipe body 40, the thickness T1 of the first cylindrical carbon fiber layer 41a is approximately 0.1 mm, and the thicknesses T2 and T3 of the second and third cylindrical carbon fiber layers 41b and 41c are approximately 0.2 mm. , the thickness T4 of the resin coating layer 42 is about 0.1 mm, and the overall thickness T5 is about 0.6 mm. The thicknesses of the first to third cylindrical carbon fiber layers 41a, 41b, 41c are derived from the thicknesses of the unidirectional and bidirectional carbon fiber sheets used when forming them. In addition, each thickness (T1, T2, T3, T4) is not limited to the above.

また、各筒形炭素繊維層４１は、管の周方向側に配置されて長手方向に延びる両端部を有すると共に、この両端部の端面同士が当接した端面当接部４１ｘを有する。なお、端面当接部４１ｘは、各筒形炭素繊維層４１の形成時に用いた１方向および２方向炭素繊維シートの両端部の端面同士が融着した部分である。
パイプ本体４０において、一の筒形炭素繊維層４１の端面当接部４１ｘと隣接する他の筒形炭素繊維層４１の端面当接部４１ｘとは相互に重ならない位置に配置されている。第１実施形態の場合、各端面当接部４１ｘは中心角度１２０°ずれた位置に配置されている。このように各端面当接部４１ｘの位置を周方向に均等にずらすことにより、パイプ本体４０に剛性の強弱部分を作らず均一化することができる。 Each cylindrical carbon fiber layer 41 has both ends arranged in the circumferential direction of the pipe and extending in the longitudinal direction, and end face contact portions 41x where the end faces of the both ends are in contact with each other. The end face abutting portion 41x is a portion where the end faces of both ends of the unidirectional and bidirectional carbon fiber sheets used when forming each cylindrical carbon fiber layer 41 are fused together.
In the pipe body 40, the end surface contact portion 41x of one cylindrical carbon fiber layer 41 and the end surface contact portion 41x of another adjacent cylindrical carbon fiber layer 41 are arranged at positions that do not overlap each other. In the case of the first embodiment, the end face contact portions 41x are arranged at positions shifted by a central angle of 120°. By equally displacing the positions of the end surface contact portions 41x in the circumferential direction in this way, the pipe body 40 can be uniform in rigidity without creating strong or weak portions.

各筒形炭素繊維層４１はそれぞれ端面当接部４１ｘを有するため、各筒形炭素繊維層４１は段差のない均一な厚みの層となって形成されている。つまり、パイプ本体の製造時に金属棒に炭素繊維シートを単に３重巻きした場合では、１重巻きの終端部と２重巻きの始端部の間および２重巻きの終端部と３重巻きの始端部の間に段差が生じるが、第１実施形態のパイプ本体４０では第１～第３筒形炭素繊維層４１ａ、４１ｂ、４１ｃの３層が独立した層であるため、このような段差が生じない。そのため、パイプ本体４０は均一な厚みで形成され、全体的に均一な剛性を有するものとなる。 Since each cylindrical carbon fiber layer 41 has an end face contact portion 41x, each cylindrical carbon fiber layer 41 is formed as a layer having a uniform thickness without steps. In other words, when the carbon fiber sheet is simply triple-wound around the metal rod during the manufacture of the pipe body, the distance between the terminal end of the single winding and the starting end of the double winding and between the terminal end of the double winding and the starting end of the triple winding A step occurs between the portions, but in the pipe body 40 of the first embodiment, since the three layers of the first to third cylindrical carbon fiber layers 41a, 41b, and 41c are independent layers, such a step occurs. do not have. Therefore, the pipe body 40 is formed with a uniform thickness and has uniform rigidity as a whole.

As shown in FIGS. 3, 9 and 10, the cover member 70 includes an elongated first member 71 having substantially the same length as the pipe body 40 and a second member 72 provided on one end side of the first member 71 . and
The first member 71 is a portion that covers the pair of conductive wires 80 and a wire member 94 of the locking mechanism portion 90 , which will be described later. A pair of longitudinally extending ribs (not shown) are provided so that the wire 94 can be positioned between the pair of conductive wires 80 in a partitioned manner. In addition, each rib may be intermittently provided in the longitudinal direction.

また、第１部材７１の一端側には幅広く形成された幅広部７１ａが設けられており、この幅広部７１ａ上にロック機構部９０の後述する第２スライド部材９３のロック解除レバー９３ａがスライド可能に支持されるようになっている。なお、幅広部７１ａの一端には、第１接続管部５０のボス部５１ｆを挿通させる孔部７１ａａと、ロック機構部９０の線材９４の一端を挿通させる孔部７１ａｂとが設けられている。 A wide portion 71a is provided at one end of the first member 71, and a lock release lever 93a of a second slide member 93 of the lock mechanism portion 90 can slide on the wide portion 71a. It is supported by One end of the wide portion 71a is provided with a hole portion 71aa through which the boss portion 51f of the first connection pipe portion 50 is inserted and a hole portion 71ab through which one end of the wire rod 94 of the lock mechanism portion 90 is inserted.

第２部材７２は、ロック解除レバー９３ａを挿通させる孔部７２ａおよびネジ５３を挿通させる筒形孔部７２ｂを有している。筒形孔部７２ｂは、第１接続管部５０のボス部５１ｆの外径より大きい内径を有し、その内面にはボス部５１ｆの上面に当接する内鍔部７２ｂａが設けられている。
第１接続管部５０のボス部５１ｆに螺着されたネジ５３によって第２部材７２が第１接続管部５０に取り付けられることによって、パイプ本体４０の一端４０ａ側の第２スライド部材９３の一部および押え部材５２が覆われる。またこれにより、押え部材５２と第２部材７２によって一対のピン形受電端子８２の一部（長手方向の中間部付近からリード線８１との接続部に亘る部分）が挟み込まれて固定される。このとき、一対のピン形受電端子８２の中間部付近は、押え部材５２の位置決め凹部５２ｂａと第２部材７２のＵ字形切欠き部７２ｃａとによって囲むように挟み込まれている。なお、第２部材７２の一端側には、一対のピン形受電端子を挿通させる一対のＵ字形切欠き部７２ｃａを有する端部壁７２ｃが設けられている。 The second member 72 has a hole 72a through which the unlocking lever 93a is inserted and a cylindrical hole 72b through which the screw 53 is inserted. The cylindrical hole portion 72b has an inner diameter larger than the outer diameter of the boss portion 51f of the first connecting pipe portion 50, and an inner collar portion 72ba is provided on the inner surface thereof to contact the upper surface of the boss portion 51f.
By attaching the second member 72 to the first connecting pipe portion 50 with a screw 53 screwed to the boss portion 51f of the first connecting pipe portion 50, one side of the second slide member 93 on the one end 40a side of the pipe main body 40 is moved. The part and the pressing member 52 are covered. Also, as a result, a portion of the pair of pin-shaped power receiving terminals 82 (the portion extending from the vicinity of the longitudinal middle portion to the connection portion with the lead wire 81) is sandwiched and fixed by the pressing member 52 and the second member 72 . At this time, the vicinity of the intermediate portion of the pair of pin-shaped power receiving terminals 82 is sandwiched between the positioning recess 52ba of the pressing member 52 and the U-shaped notch 72ca of the second member 72 so as to be surrounded. One end side of the second member 72 is provided with an end wall 72c having a pair of U-shaped cutouts 72ca through which a pair of pin-shaped power receiving terminals are inserted.

また、第２部材７２は、その内面から突出して管長手方向に延びる一対の押圧リブ７２ｄを有している。第２部材７２の一対の押圧リブ７２ｄは、第１接続管部５０のボス部５１ｆから離れた左右位置に設けられているため、一対の押圧リブ７２ｄの間のスペースに後述する一対の導電線８０およびロック機構部９０の後述の線材９４を通すことができる。 In addition, the second member 72 has a pair of pressing ribs 72d projecting from its inner surface and extending in the longitudinal direction of the pipe. Since the pair of pressing ribs 72d of the second member 72 are provided at left and right positions apart from the boss portion 51f of the first connecting tube portion 50, a pair of conductive wires described later are provided in the space between the pair of pressing ribs 72d. 80 and a wire rod 94 of the lock mechanism portion 90, which will be described later, can be passed through.

第１接続管部５０に第２部材７２が取り付けられることによって、一対の押圧リブ７２ｄが押え部材５２の一対の凸曲面部５２ｅに当接して押圧する。このとき、各押圧リブ７２ｄと各凸曲面部５２ｅとがなす角度が直角ではないため、各押圧リブ７２ｄの各凸曲面部５２ｅにかかる押圧力が周方向に分散しやすい。そのため、本実施形態では、押え部材５２の前記一対のリブ５２ｅａによって各押圧リブ７２ｄが位置決めされ、一対のリブ５２ｅａと各凸曲面部５２ｅとの間の隅部Ｎに各押圧リブ７２ｄの押圧力が集中してかかるようにしている。 By attaching the second member 72 to the first connecting pipe portion 50, the pair of pressing ribs 72d contact and press the pair of convex curved surface portions 52e of the pressing member 52. As shown in FIG. At this time, since the angle formed by each pressing rib 72d and each convex curved surface portion 52e is not a right angle, the pressing force applied to each convex curved surface portion 52e of each pressing rib 72d tends to disperse in the circumferential direction. Therefore, in this embodiment, each pressing rib 72d is positioned by the pair of ribs 52ea of the pressing member 52, and the pressing force of each pressing rib 72d is applied to the corner N between the pair of ribs 52ea and each convex curved surface portion 52e. is concentrated.

これにより、押え部材５２の一対の凹曲面部５２ａがパイプ本体４０の外面４０ｃに強い力で接触することができる。またこれにより、パイプ本体４０の一端４０ａに挿入された第１接続管部５０の挿入部５１ａの外面５１ａａと押え部材５２の内面である一対の凹曲面部５２ａとでパイプ本体４０の一端４０ａを挟み込み、かつ、この挟み込み状態を固定具としてのネジ５３にて保持することができる。 This allows the pair of concave curved surface portions 52a of the pressing member 52 to contact the outer surface 40c of the pipe body 40 with a strong force. Further, as a result, the one end 40a of the pipe main body 40 is held by the outer surface 51aa of the insertion portion 51a of the first connecting pipe portion 50 inserted into the one end 40a of the pipe main body 40 and the pair of concave curved surface portions 52a that are the inner surfaces of the pressing member 52. It can be pinched, and this pinched state can be held by screws 53 as fixtures.

したがって、パイプ本体４０の一端４０ａと第１接続管部５０の挿入部５１ａとを接着剤にて接着した場合、この接着剤による接着強度に加えて、パイプ本体４０の一端４０ａを第１接続管部５０の挿入部５１ａと押え部材５２とで挟み込んで保持することができるため、パイプ本体４０と第１接続管部５０とが互いに離れる引っ張り方向の外力に対して引張強度を高めることができる。
なお、それに加えて、パイプ本体４０と第１接続管部５０の挿入部５１ａとをビス止めしてさらに引張強度を高めるようにしてもよい。 Therefore, when the one end 40a of the pipe body 40 and the insertion portion 51a of the first connection pipe portion 50 are adhered with an adhesive, in addition to the adhesive strength of the adhesive, the one end 40a of the pipe body 40 is attached to the first connection pipe. Since the insertion portion 51a of the portion 50 and the pressing member 52 can be sandwiched and held, the tensile strength against the external force in the direction of pulling the pipe body 40 and the first connecting pipe portion 50 apart from each other can be increased.
In addition, the pipe main body 40 and the insertion portion 51a of the first connecting pipe portion 50 may be screwed to further increase the tensile strength.

［導電線］
一対の導電線８０は、絶縁材にて被覆されたリード線８１と、リード線８１の一端にハンダ付けされたピン形受電端子８２と、リード線８１の他端にハンダ付けされたクリップ形給電端子８３とをそれぞれ備える。なお、リード線８１とピン形受電端子８２との接合はハンダ付け以外にも、スポット溶接やカシメなどで行ってもよい。 [Conductive wire]
The pair of conductive wires 80 includes a lead wire 81 covered with an insulating material, a pin-type power receiving terminal 82 soldered to one end of the lead wire 81, and a clip-type power supply terminal soldered to the other end of the lead wire 81. terminal 83, respectively.
