　導線付きパイプ２１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２１ａ1～２１ａ3を用いた次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、第１の方法として、第１筒形炭素繊維層２１ａ1を軸棒に巻き付けて成型し、その上に第２筒形炭素繊維層２１ａ2を巻き付けて成型し、その上にフラットケーブル２１ｂを載せ、その上に第３筒形炭素繊維層２１ａ3を巻き付けて成型する。
　なお、図８は、第１の方法で形成した導線付きパイプ２１の横断面を示している。 The pipe with conducting wire 21 can be manufactured by molding and laminating a commercially available prepreg sheet by the following method using the first to third cylindrical carbon fiber layers 21a 1 to 21a 3 .
For example, as a first method, the first cylindrical carbon fiber layer 21a 1 is wound around a shaft rod and molded, the second cylindrical carbon fiber layer 21a 2 is wound thereon and molded, and a flat cable 21b is formed thereon. And the third cylindrical carbon fiber layer 21a 3 is wound thereon and molded.
In addition, FIG. 8 has shown the cross section of the pipe 21 with conducting wire formed with the 1st method.
　また、第２の方法として、図１０に示すように、第１～第３筒形炭素繊維層２１ａ1～２１ａ3を相互に少し重なるように横に並べ、かつ第３筒形炭素繊維層２１ａ3上にフラットケーブル２１ｂを載せた後、第１筒形炭素繊維層２１ａ1側から順に各筒形炭素繊維層２１ａを軸棒に巻き付けて成型する。なお、図１０は実施形態１における変形例１の導線付きパイプの横断面図である。 As a second method, as shown in FIG. 10, the first to third cylindrical carbon fiber layers 21a 1 to 21a 3 are arranged side by side so as to slightly overlap each other, and the third cylindrical carbon fiber layer 21a is arranged. 3. After the flat cable 21b is placed on the third cylindrical carbon fiber layer 21a, the cylindrical carbon fiber layers 21a are wound around the shaft rod in order from the first cylindrical carbon fiber layer 21a 1 side. In addition, FIG. 10 is a cross-sectional view of a pipe with a conducting wire according to Modification 1 of Embodiment 1.
　また、第３の方法として、図１１に示すように、１枚の２方向炭素繊維シート２１ａｍを軸棒に２重巻きした後、未だ巻いていない２方向炭素繊維シート２１ａｍ上にフラットケーブル１２ｂを載せ、その後、フラットケーブル１２ｂと共に２方向炭素繊維シートを３重巻きして成型する。なお、図１１は実施形態１における変形例２の導線付きパイプの横断面図である。 Further, as a third method, as shown in FIG. 11, after a single bi-directional carbon fiber sheet 21 am is wound twice around a shaft rod, the flat cable 12 b is placed on the un-rolled bi-directional carbon fiber sheet 21 am. After that, the bi-directional carbon fiber sheet is wound with the flat cable 12b in a triple manner and molded. In addition, FIG. 11 is a cross-sectional view of a pipe with a conducting wire according to Modification 2 of Embodiment 1.
　実施形態１の場合、形成後の導線付きパイプ２１の両端部におけるフラットケーブル２１ｂの幅中央位置（一対の金属テープ２１ｂ3の間）に、第１および第２接続管部２２、２３との接続位置を位置決めするための小さい切欠き部２１ｎが切削によって形成される。その際、図６に示すように、フラットケーブル２１ｂの両端部における一対の金属テープ２１ｂ3の間に切り込みが形成されてもよい。
　なお、導線付きパイプ２１の両端部の切欠き部２１ｎは、フラットケーブル２１ｂからずれた位置（例えば、中心角度１８０°ずれた位置）に形成してもよい。 In the case of the first embodiment, the first and second connecting pipe portions 22 and 23 are connected to the width center position (between the pair of metal tapes 21b 3 ) of the flat cable 21b at both ends of the pipe 21 with the conductive wire after the formation. A small notch 21n for positioning the position is formed by cutting. In that case, as shown in FIG. 6, a notch may be formed between the pair of metal tapes 21b 3 at both ends of the flat cable 21b.
In addition, you may form the notch part 21n of the both ends of the pipe 21 with conducting wire in the position (For example, position shifted | deviated from the center angle 180 degrees) from the flat cable 21b.
　また、前記第１の方法で形成した導線付きパイプ２１の場合、各筒形炭素繊維層２１ａは、管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２１ａｘを有する（図７）。なお、端面当接部２１ａｘは、各筒形炭素繊維層２１ａ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。
　導線付きパイプ２１において、一の筒形炭素繊維層２１ａの端面当接部２１ａｘと隣接する他の筒形炭素繊維層２１ａの端面当接部２１ａｘとは相互に重ならない位置に配置されている。実施形態１の場合、各当接端面部２１ａｘは中心角度１２０°ずれた位置に配置されている。このように各当接端面部２１ａｘの位置を周方向に均等にずらすことにより、管本体に剛性の強弱部分を作らず均一化することができる。また、各筒形炭素繊維層２１ａはそれぞれ端面当接部２１ａｘを有するため、各筒形炭素繊維層２１ａは段差のない均一な厚みの層となって形成されている。 Moreover, in the case of the pipe 21 with a conductor formed by the first method, each cylindrical carbon fiber layer 21a has both end portions extending in the longitudinal direction of the tube, and the end surface contact where the end surfaces of the both end portions are in contact with each other. Part 21ax (FIG. 7). The end surface abutting portions 21ax are portions where the end surfaces of both end portions of the one-way and two-way carbon fiber sheets used at the time of forming each cylindrical carbon fiber layer 21a are fused.
In the pipe 21 with a conducting wire, the end surface abutting portion 21ax of one cylindrical carbon fiber layer 21a and the end surface abutting portion 21ax of another cylindrical carbon fiber layer 21a adjacent to each other are arranged at positions that do not overlap each other. In the case of the first embodiment, each contact end surface portion 21ax is disposed at a position shifted by a central angle of 120 °. Thus, by uniformly shifting the position of each contact end surface portion 21ax in the circumferential direction, it is possible to make the tube main body uniform without making a rigid strength portion. Moreover, since each cylindrical carbon fiber layer 21a has the end surface contact part 21ax, each cylindrical carbon fiber layer 21a is formed as a layer of uniform thickness without a level | step difference.
　図１０に示す第２の方法（変形例１）で形成した導電付きパイプ２１ｘの場合、第１～第３筒形炭素繊維層２１ａ1～２１ａ3の重なり部分を同じ位置に合わせることにより、重なり部分以外の部分の厚みを概ね炭素繊維層の３層構造にしてパイプ本体２１Ａｘの全重量を抑えるようにしている。
　図１１に示す第３の方法（変形例２）で形成した導電付きパイプ２１ｙの場合、始端部の端面と終端部の端面の位置を一致させることにより、局所的に厚みを厚くせずに剛性を均一化している。 In the case of the conductive pipe 21x formed by the second method (Modification 1) shown in FIG. 10, the overlapping portions of the first to third cylindrical carbon fiber layers 21a 1 to 21a 3 are aligned at the same position, thereby overlapping. The thickness of the portion other than the portion is generally a three-layer structure of carbon fiber layers so as to suppress the total weight of the pipe body 21Ax.
In the case of the conductive pipe 21y formed by the third method shown in FIG. 11 (Modification 2), the end face of the end portion and the end face of the end portion are made to coincide with each other so that the rigidity is not locally increased. Is uniform.
　実施形態１の導線付きパイプ２１によれば、次の効果が得られる。
（Ｉ）フラットケーブル２１ｂの厚さＴ6分の膨らみが外面および内面にほとんど反映されないため、同外径のパイプ仕様において、配線による内径のロスを減らすことができると共に、外観デザインの影響を極めて少なくすることができる。
（ＩＩ）従来のような配線の支持部品が不要となることに加え、パイプ本体２１Ａをドライカーボンで形成することにより、大幅な軽量化を実現できる。
（ＩＩＩ）従来のような配線の支持部品が不要であり、かつパイプ本体２１Ａの形成時に導線（フラットケーブル２１ｂ）の取り付けが同時に行われるため、パイプ本体２１Ａの形成後の導線の取り付け工程が不要となって製造効率が向上する。 According to the pipe 21 with conducting wire of the first embodiment, the following effects can be obtained.
(I) for the bulge in the thickness T 6 minutes of the flat cable 21b is hardly reflected in the outer and inner surfaces, the pipe specifications Dosoto径, it is possible to reduce the loss of internal diameter by wire, extremely influence the exterior design Can be reduced.
(II) In addition to eliminating the need for conventional wiring support parts, the pipe body 21A can be made of dry carbon, thereby significantly reducing the weight.
(III) A wiring support part as in the prior art is not necessary, and the conductor (flat cable 21b) is attached at the same time when the pipe body 21A is formed, so the conductor attachment process after the pipe body 21A is formed is unnecessary. Thus, manufacturing efficiency is improved.
