Description

ワイヤハーネス用の外装部材、及びワイヤハーネスExterior member for wire harness, and wire harness
　本発明は、ワイヤハーネス用の外装部材と、この外装部材を構成に含んでなるワイヤハーネスとに関する。 The present invention relates to an exterior member for a wire harness and a wire harness including the exterior member in its configuration.
　例えば、ハイブリッド自動車や電気自動車に搭載される高電圧の機器間を電気的に接続するためとしてワイヤハーネスが用いられる。近年の動向を見ると、ワイヤハーネスは、配索スペースに配慮された構成及び構造のものが採用されている。 For example, a wire harness is used to electrically connect high voltage devices mounted on a hybrid vehicle or an electric vehicle. Looking at trends in recent years, wire harnesses having a configuration and structure that take into account the wiring space are adopted.
　下記特許文献１に開示されたワイヤハーネスは、導電路と、この導電路を保護するための合成樹脂製の外装部材（電線保護チューブ等）とを備えて構成される。外装部材は、ワイヤハーネスを三次元的な複雑なスペースに配索するために、蛇腹管形状の可撓管部と、ストレート管形状のストレート管部とを有する。外装部材は、これら可撓管部とストレート管部とが連続するようにして樹脂成形される。このような外装部材を採用すれば、三次元的な複雑なスペースであってもワイヤハーネスの配策が可能になる。 The wire harness disclosed in Patent Document 1 below includes a conductive path and a synthetic resin exterior member (such as a wire protection tube) for protecting the conductive path. The exterior member has a bellows tube-shaped flexible tube portion and a straight tube-shaped straight tube portion in order to route the wire harness in a three-dimensional complex space. The exterior member is resin-molded so that the flexible tube portion and the straight tube portion are continuous. If such an exterior member is employed, the wiring harness can be arranged even in a three-dimensional complicated space.
　従来、複数の電線を束ねた電線束の各電線を配索経路に沿って分岐させながら設置するワイヤハーネスは、電線束を電線保護チューブによって覆うことによって保護されている。
　例えば、特許文献２に記載の電線保護チューブは、電線保護チューブの一部にスリットを開けて、スリットの対向する開口端縁面を分岐方向に向けて外側に折り曲げその孔から支線を引き出すことによって電線を分岐し、開口端縁面のエッジを電線に接触し難くすることによって、エッジと電線との擦れを防ぎ、結果的に、電線の損傷を防止するようにしている。 2. Description of the Related Art Conventionally, a wire harness that is installed while branching each electric wire in a bundle of wires bundled with a plurality of wires along a wiring path is protected by covering the wire bundle with a wire protection tube.
For example, the electric wire protection tube described in Patent Document 2 is formed by opening a slit in a part of the electric wire protection tube, bending the opening edge surface facing the slit in the branching direction, and pulling out the branch line from the hole. By branching the electric wire and making it difficult for the edge of the opening edge surface to contact the electric wire, rubbing between the edge and the electric wire is prevented, and as a result, damage to the electric wire is prevented.

　上記特許文献１に開示された従来のワイヤハーネスにあっては、樹脂製の外装部材を採用することから、金属パイプからなる外装部材のワイヤハーネスと比べて軽量化を図ることができるという効果を奏する。しかしながら、近年では更なる軽量化の要望があり、そのためには、外装部材としての強度を確保しつつ軽量化を図らなければならないと本願発明者は考える。 The conventional wire harness disclosed in Patent Document 1 employs a resin exterior member, so that the weight can be reduced as compared with a wire harness of an exterior member made of a metal pipe. Play. However, in recent years, there has been a demand for further weight reduction, and for this purpose, the inventor of the present application thinks that weight reduction must be achieved while ensuring strength as an exterior member.
　また、上記特許文献１に開示された従来のワイヤハーネスにあっては、車両への配策作業において、この逆付けをしてしまうという虞がある。すなわち、ワイヤハーネスの一端と他端とを逆に取り付けてしまうという虞がある。原因の一つとしては、ワイヤハーネスの外観の大半を占める外装部材を単に見ただけでは、ワイヤハーネスの配策に係る方向性が分かり難いからである。 Further, in the conventional wire harness disclosed in Patent Document 1, there is a possibility that this reverse is performed in the routing work to the vehicle. That is, there is a possibility that one end and the other end of the wire harness are attached in reverse. One reason is that simply looking at the exterior member occupying most of the appearance of the wire harness makes it difficult to understand the direction of the wire harness arrangement.
　また、上記特許文献２に記載の電線保護チューブは、振動等によって折り曲げ部分の折り曲げ方向が変化し、開口端縁面のエッジが電線側に向いた場合、エッジが常に電線に接触する状態となり、結果的に電線が損傷するおそれがあった。 Moreover, the electric wire protection tube of the said patent document 2 will be in the state which always contacts an electric wire when the bending direction of a bending part changes by vibration etc., and the edge of an opening edge surface faces the electric wire side, As a result, there was a possibility that the electric wire was damaged.
　本発明の第１の目的は、上記した事情に鑑みてなされたもので、強度を確保しつつ軽量化を図ることが可能なワイヤハーネス用の外装部材、及びワイヤハーネスを提供することである。 The first object of the present invention is to provide an exterior member for a wire harness and a wire harness that can be reduced in weight while ensuring strength.
　本発明の第２の目的は、上記した事情に鑑みてなされたもので、車両への配策作業における逆付け防止を図ることが可能なワイヤハーネス用の外装部材、及びワイヤハーネスを提供することである。 The second object of the present invention has been made in view of the above circumstances, and provides an exterior member for a wire harness and a wire harness that can prevent reverse installation in a vehicle routing operation. It is.
　本発明の第３の目的は、上記に鑑みてなされたものであって、分岐部分によって電線が損傷することを防ぐことができる電線保護チューブを提供することである。 The third object of the present invention has been made in view of the above, and is to provide an electric wire protection tube capable of preventing an electric wire from being damaged by a branched portion.

(1) An exterior member for a wire harness that is formed into a tubular shape by resin molding in order to insert and protect a conductive path, and the exterior member is for fixing the wire harness at a predetermined position. An exterior member for a wire harness in which a plurality of fixing portions or fixing members are provided on the outside, and a thin portion is formed on the inner side according to the interval or arrangement of the adjacent fixing portions or fixing members.

　上記（１）又は（２）の構成を有するワイヤハーネス用の外装部材は、薄肉部を有する外装部材であり、この薄肉部は例えば隣り合う固定部又は固定部材の間隔が狭くなる部分に合わせて形成される。薄肉部の形成により外装部材の肉厚が薄くなるが、固定部又は固定部材が固定対象に固定された状態になれば強度低下分が補われ、結果、外装部材として必要な強度を確保することができる。従って、上記間隔が狭くなる部分で外装部材の軽量化を図ることができる。尚、上記（１）又は（２）の構成の外装部材によれば、内側に薄肉部が形成されることから、軽量化のために外観が変わることがなく、結果、配策作業や配策スペースに支障を来すことはない。この他、上記（１）又は（２）の構成の外装部材によれば、軽量化に伴って樹脂材料の低減を図ることもできる。すなわち、コスト低減を図ることもできる。 The exterior member for a wire harness having the above-described configuration (1) or (2) is an exterior member having a thin portion, and this thin portion conforms to, for example, an adjacent fixing portion or a portion where the interval between the fixing members is narrow. It is formed. The thickness of the exterior member is reduced by the formation of the thin part, but if the fixed part or the fixed member is fixed to the object to be fixed, the decrease in strength is compensated, and as a result, the necessary strength as the exterior member is secured. Can do. Accordingly, it is possible to reduce the weight of the exterior member at the portion where the interval is narrowed. In addition, according to the exterior member having the above configuration (1) or (2), since the thin portion is formed on the inner side, the appearance does not change for weight reduction. There is no hindrance to the space. In addition, according to the exterior member having the above configuration (1) or (2), the resin material can be reduced as the weight is reduced. That is, cost reduction can be achieved.
　（３）　上記（１）又は（２）に記載のワイヤハーネス用の外装部材と、前記外装部材に挿通される導電路と、前記外装部材の外側に複数設けられる固定部又は固定部材とを備えるワイヤハーネス。 (3) The wire harness exterior member according to (1) or (2) above, a conductive path inserted through the exterior member, and a plurality of fixing portions or fixing members provided outside the exterior member.

　上記（３）の構成を有するワイヤハーネスによれば、外装部材における薄肉部の分だけ軽量化される。 According to the wire harness having the configuration (3), the weight is reduced by the thin portion of the exterior member.
　本発明の第２の目的は、下記（４）～（１０）の構成により達成される。
　（４）　導電路を挿通して保護するために管体形状に形成されるワイヤハーネス用の外装部材であって、前記外装部材は樹脂成形品であり、視認のための印が成形時に形成され、前記印が内面を凹ませ且つ外面を突出させて形成されるワイヤハーネス用の外装部材。 The second object of the present invention is achieved by the following configurations (4) to (10).
(4) An exterior member for a wire harness that is formed into a tubular shape to pass through a conductive path and protect the wire. The exterior member is a resin molded product, and a mark for visual recognition is formed at the time of molding. An exterior member for a wire harness, wherein the mark is formed by recessing the inner surface and projecting the outer surface.
　（５）　上記（４）に記載のワイヤハーネス用の外装部材であって、前記印が管軸に対し軸対称に形成されるワイヤハーネス用の外装部材。 (5) The wire harness exterior member according to (4), wherein the mark is formed symmetrically with respect to the tube axis.
　（６）　上記（４）又は（５）に記載のワイヤハーネス用の外装部材であって、前記印が対称形状の矢印であるワイヤハーネス用の外装部材。 (6) An exterior member for a wire harness according to (4) or (5) above, wherein the mark is a symmetrical arrow.
　（７）　上記（４）、（５）又は（６）に記載のワイヤハーネス用の外装部材であって、前記外装部材は可撓管部とストレート管部とを有し、前記ストレート管部に前記印が配置形成されるワイヤハーネス用の外装部材。 (7) The exterior member for a wire harness according to (4), (5), or (6), wherein the exterior member has a flexible tube portion and a straight tube portion, An exterior member for a wire harness in which the mark is arranged and formed.
　（８）　上記（７）に記載のワイヤハーネス用の外装部材であって、前記可撓管部が蛇腹凹部及び蛇腹凸部を有する蛇腹管形状に形成され、前記印が前記蛇腹凸部よりも低く形成されるワイヤハーネス用の外装部材。 (8) The exterior member for the wire harness according to (7), wherein the flexible tube portion is formed in a bellows tube shape having a bellows concave portion and a bellows convex portion, and the mark is more than the bellows convex portion. An exterior member for a wire harness that is formed low.
　（９）　上記（７）又は（８）に記載のワイヤハーネス用の外装部材であって、前記印が前記ストレート管部における前記可撓管部近傍に配置形成されるワイヤハーネス用の外装部材。 (9) The exterior member for a wire harness according to (7) or (8), wherein the mark is arranged and formed in the vicinity of the flexible tube portion in the straight tube portion.
　上記（４）～（９）の構成を有する外装部材によれば、視認のための印が形成されるものであることから、車両へのワイヤハーネスの配策作業において印を見て確認することで逆付けが防止される。
　印は、外装部材の内面を凹ませ且つ外面を突出させて形成されることから、形状面で次の場合と異なる。すなわち、外面に対しマーキングをして形成される場合と異なる。また、外面に対し単に肉盛りをして形成される場合と異なる。前者の場合は、マーキングであることから平面的であり、作業者が見る角度によっては見難くなってしまうという虞がある。後者の場合は、肉盛りをすることから外面から突出する形状になり、前者と比べて視認性は向上するが、反面、肉盛りをした分だけ他の部分との厚みが異なってしまい、そのため樹脂成形性に支障を来して例えばヒケ等の不具合を引き起こしてしまうという虞がある。
　上記（４）～（９）の構成を有する外装部材では、内面を凹ませ且つ外面を突出させた形状の印を採用することから上記のような虞がなくなり、結果、有用である。尚、内面を凹ませ且つ外面を突出させて印を形成することから、薄肉になって強度の低下が懸念されるが、そのような心配はない。何故ならば、内面を凹ませることで外装部材の管軸からの距離が増えて断面二次モーメントが大きくなるからである。上記（４）～（９）の構成を有する外装部材は、断面二次モーメントを考慮して印が形成されることから剛性の低下がなく、結果、外装部材としての機能を損なうことはない。 According to the exterior member having the configuration of (4) to (9) above, since a mark for visual recognition is formed, it is necessary to check by checking the mark in the routing work of the wire harness to the vehicle. This prevents reverse installation.
Since the mark is formed by recessing the inner surface of the exterior member and projecting the outer surface, the shape is different from the following case. That is, it is different from the case where the outer surface is marked. Moreover, it differs from the case where it forms simply by building up with respect to an outer surface. In the former case, since it is a marking, it is planar, and it may be difficult to see depending on the angle viewed by the operator. In the case of the latter, it becomes a shape protruding from the outer surface because it builds up, and the visibility is improved compared to the former, but on the other hand, the thickness of the other part is different by the amount of the buildup, so There is a risk that the resin moldability will be hindered, causing problems such as sink marks.
The exterior member having the above-described configurations (4) to (9) employs a mark having a shape in which the inner surface is recessed and the outer surface is protruded, and thus there is no such a concern, and as a result, it is useful. Incidentally, since the mark is formed by denting the inner surface and projecting the outer surface, there is a concern that the thickness is reduced and the strength is lowered, but there is no such concern. This is because the concave moment of the inner surface increases the distance from the tube axis of the exterior member and increases the cross-sectional second moment. The exterior member having the above configurations (4) to (9) is formed with a mark in consideration of the cross-sectional second moment, so that the rigidity is not lowered, and as a result, the function as the exterior member is not impaired.
　（１０）　上記（４）、（５）、（６）、（７）又は（８）に記載のワイヤハーネス用の外装部材と、前記外装部材に挿通される導電路とを備えるワイヤハーネス。 (10) A wire harness comprising the exterior member for a wire harness described in (4), (5), (6), (7) or (8) above, and a conductive path inserted through the exterior member.
　上記（１０）の構成を有するワイヤハーネスによれば、外装部材に形成された印をもとに車両への配策作業をすることで逆付けが防止される。 According to the wire harness having the configuration of (10) above, reverse installation is prevented by performing the routing work on the vehicle based on the mark formed on the exterior member.
　本発明の第３の目的は、下記（１１）～（１２）の構成により達成される。 The third object of the present invention is achieved by the following configurations (11) to (12).
　（１１）　幹線と、前記幹線から分岐する支線とを有する電線束の前記幹線の外周を覆う幹線筒部と、前記電線束の分岐部分の前記支線の外周を覆うように前記幹線筒部から分岐する分岐筒部と、を有する電線保護チューブであって、前記分岐筒部は、分岐方向に向けて突出するように前記幹線筒部と一体的に設けられ、かつ、弾性的に屈曲自在な屈曲自在部が前記分岐筒部の開口側の端部の周方向に沿って設けられた電線保護チューブ。 (11) A trunk tube portion covering an outer periphery of the trunk wire of a wire bundle having a trunk line and a branch line branched from the trunk line, and a branch from the trunk tube portion so as to cover an outer periphery of the branch line of the branch portion of the wire bundle. An electric wire protection tube, wherein the branch tube portion is provided integrally with the main tube portion so as to protrude toward the branch direction, and is elastically bendable. An electric wire protection tube in which the free part is provided along the circumferential direction of the end part on the opening side of the branch cylinder part.
　（１２）　上記（１１）に記載の電線保護チューブであって、前記分岐筒部は、軸方向で筒内径を変化するように、基端側に筒内径を小さくして設けた小径筒部と、開口端側に該小径筒部に比して筒内径を大きくして設けた大径筒部とを有し、前記屈曲自在部は、前記小径筒部から前記大径筒部に筒内径を大きく変化するように軸方向から径外方向に屈曲した前記分岐筒部の壁である電線保護チューブ。 (12) The electric wire protection tube according to (11), wherein the branch tube portion includes a small-diameter tube portion provided at a proximal end side with a small tube inner diameter so that the tube inner diameter changes in an axial direction.

An electric wire protection tube which is a wall of the branched tube portion bent from the axial direction to the radially outward direction so as to change greatly.
　上記（１）、（２）に記載されたワイヤハーネス用の外装部材によれば、強度を確保しつつ軽量化を図ることが可能な外装部材を提供することができるという効果を奏する。 According to the exterior member for a wire harness described in the above (1) and (2), there is an effect that it is possible to provide an exterior member capable of reducing the weight while ensuring the strength.
　上記（３）に記載されたワイヤハーネス用の外装部材によれば、強度を確保しつつ軽量化を図ることが可能なワイヤハーネスを提供することができるという効果を奏する。 According to the exterior member for a wire harness described in the above (3), there is an effect that it is possible to provide a wire harness that can achieve weight reduction while ensuring strength.
　上記（４）に記載されたワイヤハーネス用の外装部材によれば、内面を凹ませ且つ外面を突出させた形状の印を有する外装部材であることから、ワイヤハーネスを車両へ配策する際に印を見て確認することで逆付けを防止することができるという効果を奏する。 According to the exterior member for a wire harness described in the above (4), since the exterior member has a mark having a shape in which the inner surface is recessed and the outer surface protrudes, when routing the wire harness to the vehicle By seeing and confirming the mark, it is possible to prevent reverse attachment.
　上記（５）に記載されたワイヤハーネス用の外装部材によれば、管軸に対し軸対称に印を形成することから複数の印であり、このように複数であれば視認性を向上させることができるのは勿論のこと、外装部材としての成形状態を安定させたり機能を十分に発揮させたりすることができるという効果を奏する。 According to the exterior member for a wire harness described in the above (5), since the marks are formed symmetrically with respect to the tube axis, there are a plurality of marks. As a matter of course, there is an effect that the molded state as the exterior member can be stabilized and the function can be sufficiently exhibited.
　上記（６）に記載されたワイヤハーネス用の外装部材によれば、対称形状の矢印を視認のための印とすることから、ワイヤハーネスの配策に係る方向性をより一層分かり易くすることができるという効果を奏する。また、対称形状の矢印であることから、外装部材としての成形状態を安定させたりすることができるという効果を奏する。 According to the exterior member for a wire harness described in (6) above, since the symmetrical arrow is used as a mark for visual recognition, the directionality related to the wiring harness can be further easily understood. There is an effect that can be done. Moreover, since it is a symmetrical arrow, there exists an effect that the shaping | molding state as an exterior member can be stabilized.
　上記（７）に記載されたワイヤハーネス用の外装部材によれば、可撓管部とストレート管部とを有する外装部材であり、剛性を確保できるストレート管部に印を形成することから、外装部材としての機能を損なうことがないという効果を奏する。 According to the exterior member for a wire harness described in (7) above, it is an exterior member having a flexible tube portion and a straight tube portion, and forms a mark on the straight tube portion that can ensure rigidity. There exists an effect that the function as a member is not impaired.
　上記（８）に記載されたワイヤハーネス用の外装部材によれば、可撓管部の蛇腹凸部よりも低く印を形成することから、印によって配策スペースがなくなってしまうことはない。すなわち、印を形成しても従来同様に配策をすることができるという効果を奏する。 According to the exterior member for a wire harness described in (8) above, since the mark is formed lower than the bellows convex part of the flexible tube part, the routing space is not lost by the mark. That is, even if the mark is formed, there is an effect that the arrangement can be made as in the conventional case.
　上記（９）に記載されたワイヤハーネス用の外装部材によれば、ストレート管部における可撓管部近傍に印を配置形成することから、単に中央に配置形成する場合と比べて、ワイヤハーネスの配策に係る方向性を分かり易くすることができるという効果を奏する。 According to the exterior member for a wire harness described in the above (9), since the mark is arranged and formed in the vicinity of the flexible tube portion in the straight tube portion, the wire harness of the wire harness is simply compared with the case where it is arranged and formed in the center. There is an effect that the directionality related to the arrangement can be easily understood.
　上記（１０）に記載されたワイヤハーネスによれば、車両への配策作業における逆付け防止を図ることが可能なワイヤハーネスを提供することができるという効果を奏する。 According to the wire harness described in the above (10), there is an effect that it is possible to provide a wire harness capable of preventing reverse installation in the routing work to the vehicle.
　上記（１１）に記載された電線保護チューブは、前記分岐筒部を分岐方向に向けて突出するように前記幹線筒部と一体的に設けているので、分岐部分のエッジを開口端縁面だけに絞りこみ、しかも、電線が前記分岐筒部の開口端縁面のエッジに接触すると、エッジが電線Ｗを押圧する力を軽減するように前記屈曲自在部が弾性的に屈曲するようになっているので、エッジと電線との擦れを防ぎ、結果的に、分岐部分によって電線が損傷することを防ぐことができる。 Since the electric wire protection tube described in (11) is provided integrally with the trunk tube portion so that the branch tube portion protrudes in the branching direction, the edge of the branch portion is only the opening edge surface. In addition, when the electric wire comes into contact with the edge of the opening end surface of the branch tube portion, the bendable portion is elastically bent so as to reduce the force with which the edge presses the electric wire W. Therefore, rubbing between the edge and the electric wire can be prevented, and as a result, the electric wire can be prevented from being damaged by the branch portion.
　上記（１２）に記載された電線保護チューブは、前記分岐筒部の筒内径を変化させることによって、前記屈曲自在部を形成するようにしているので、前記電線保護チューブが樹脂成形品である場合、金型によって容易に一体的に成形することができる。 Since the electric wire protection tube described in the above (12) is configured to form the bendable part by changing the inner diameter of the branch cylinder part, the electric wire protection tube is a resin molded product. , And can be easily formed integrally with a mold.

　図２及び図３において、外装部材２４は、エアブロー方式又はバキューム方式による装置を用いた樹脂成形にて一本の真っ直ぐな管体形状のものに形成される（使用前は真っ直ぐである）。このような外装部材２４には、可撓性を有する可撓管部２８～３０と、ストレートに配索する部分としてのストレート管部（短いストレート管部３１、長いストレート管部３２）とが形成される。本第１実施形態においては、図中左側から（ワイヤハーネス９の前端側から）可撓管部２８、短いストレート管部３１、可撓管部２９、長いストレート管部３２、可撓管部３０となるように可撓管部とストレート管部とが交互に配置される。 2 and 3, the exterior member 24 is formed into a single straight tubular body by resin molding using an air blow type or vacuum type device (it is straight before use). Such an exterior member 24 is formed with flexible flexible tube portions 28 to 30 and straight tube portions (short straight tube portion 31 and long straight tube portion 32) as a straight wiring portion. Is done. In the first embodiment, from the left side of the drawing (from the front end side of the wire harness 9), the flexible tube portion 28, the short straight tube portion 31, the flexible tube portion 29, the long straight tube portion 32, and the flexible tube portion 30 are used. The flexible tube portions and the straight tube portions are alternately arranged so that
　可撓管部２８～３０は、固定対象２３（ワイヤハーネス配索先）の曲げ位置及び曲げ長さに合わせて配置形成される。可撓管部２８～３０の長さは一定でなく、固定対象２３に合わせて必要な長さでそれぞれ形成される。このような可撓管部２８～３０は、ワイヤハーネス９の梱包状態や輸送時、車両への経路配索時に、それぞれ所望の角度で撓ませられる。可撓管部２８～３０は、撓ませて曲げ形状にすることができるとともに、図３に示すような真っ直ぐな元の状態（樹脂成形時の状態）に戻すことも当然にできるように形成される。 The flexible tube portions 28 to 30 are arranged and formed in accordance with the bending position and bending length of the fixing object 23 (wire harness wiring destination). The lengths of the flexible tube portions 28 to 30 are not constant, and are formed with necessary lengths according to the fixing object 23, respectively. Such flexible tube portions 28 to 30 are bent at a desired angle when the wire harness 9 is packed, transported, or routed to the vehicle. The flexible tube portions 28 to 30 can be bent to have a bent shape, and can be naturally returned to the original state (the state at the time of resin molding) as shown in FIG. The
　可撓管部２８～３０は、本第１実施形態において蛇腹管形状に形成される（可撓性を有すれば形状は特に限定されない）。具体的には、周方向の蛇腹凹部３３及び蛇腹凸部３４を有するとともに、これら蛇腹凹部３３及び蛇腹凸部３４が管軸方向に交互に連続するように形成される。 The flexible tube portions 28 to 30 are formed in a bellows tube shape in the first embodiment (the shape is not particularly limited as long as it has flexibility). Specifically, the bellows concave portion 33 and the bellows convex portion 34 in the circumferential direction are provided, and the bellows concave portion 33 and the bellows convex portion 34 are formed alternately and continuously in the tube axis direction.
　図２～図４において、短いストレート管部３１及び長いストレート管部３２は、可撓管部２８～３０のような可撓性を持たない部分として形成される。また、短いストレート管部３１及び長いストレート管部３２は、梱包状態や輸送時、経路配索時において曲がらない部分としても形成される（曲がらない部分とは、可撓性を積極的に持たせない部分という意味である）。短いストレート管部３１及び長いストレート管部３２は、真っ直ぐのびた管体形状に形成される。 2 to 4, the short straight tube portion 31 and the long straight tube portion 32 are formed as portions having no flexibility such as the flexible tube portions 28 to 30. Further, the short straight pipe portion 31 and the long straight pipe portion 32 are also formed as a portion that does not bend during packing, transportation, or route routing (the portion that does not bend positively has flexibility). Meaning no part). The short straight tube portion 31 and the long straight tube portion 32 are formed in a straight tube shape.
　短いストレート管部３１及び長いストレート管部３２の外面には、固定部材２０ａ～２０ｄを取り付ける部分としての固定部材取付部３５が複数形成される。固定部材取付部３５は、短いストレート管部３１に一つ、長いストレート管部３２に三つ形成される（数は一例である）。固定部材取付部３５は、一対の移動規制部３６と、着脱部３７とを含んで構成される（取り付けの部分であれば図示構成に限らないものとする）。一対の移動規制部３６は、環状のフランジ形状に形成される。一対の移動規制部３６は、着脱部３７の両側に配置形成される。尚、固定部材取付部３５の配置は、固定部材２０ａ～２０ｄの上記間隔と同様の内容であり説明を省略する。 A plurality of fixing member attachment portions 35 are formed on the outer surfaces of the short straight tube portion 31 and the long straight tube portion 32 as portions for attaching the fixing members 20a to 20d. One fixing member attachment portion 35 is formed on the short straight tube portion 31 and three on the long straight tube portion 32 (the number is an example). The fixing member attaching part 35 is configured to include a pair of movement restricting parts 36 and an attaching / detaching part 37 (if it is an attaching part, it is not limited to the illustrated structure). The pair of movement restricting portions 36 is formed in an annular flange shape. The pair of movement restricting portions 36 are arranged and formed on both sides of the attaching / detaching portion 37. The arrangement of the fixing member mounting portion 35 has the same contents as the above-described interval between the fixing members 20a to 20d, and will not be described.
　短いストレート管部３１及び長いストレート管部３２の内面には、本第１実施形態の特徴部分である薄肉部３８～４０が形成される。薄肉部３８～４０は、短いストレート管部３１及び長いストレート管部３２の肉厚を内側から薄くすることにより形成される。このような薄肉部３８～４０は、固定部材２０ａ～２０ｄの間隔や配置に応じて形成される。薄肉部３８～４０は、肉厚を薄くして形成されることから、軽量化を図ることができる部分として有効である。薄肉部３８～４０は、外装部材２４に係る樹脂成形の装置を適宜制御することにより、具体的には樹脂成形速度や樹脂材の供給量を制御することにより形成される。 On the inner surfaces of the short straight tube portion 31 and the long straight tube portion 32, thin-walled portions 38 to 40 that are characteristic portions of the first embodiment are formed. The thin portions 38 to 40 are formed by reducing the thickness of the short straight tube portion 31 and the long straight tube portion 32 from the inside. Such thin portions 38 to 40 are formed according to the interval and arrangement of the fixing members 20a to 20d. Since the thin portions 38 to 40 are formed with a small thickness, they are effective as portions that can be reduced in weight. The thin portions 38 to 40 are formed by appropriately controlling the resin molding apparatus related to the exterior member 24, specifically by controlling the resin molding speed and the supply amount of the resin material.
　薄肉部３８～４０は、固定部材２０ａ～２０ｄの間隔や配置に応じて形成範囲が設定される。この形成範囲は、固定対象２３への固定部材２０ａ～２０ｄの固定を行った状態で外装部材２４の必要強度を確保できるような範囲に設定される。 The formation range of the thin portions 38 to 40 is set according to the interval and arrangement of the fixing members 20a to 20d. This formation range is set to a range in which the required strength of the exterior member 24 can be secured in a state where the fixing members 20a to 20d are fixed to the fixing object 23.
　薄肉部３８は、固定部材２０ａが取り付けられる短いストレート管部３１の内面全体に形成される。本第１実施形態においては、固定部材２０ａが比較的狭い間隔で固定部材２０ｂに隣り合うように配設されることから、短いストレート管部３１の内面全体に薄肉部３８が形成されても必要な強度を固定部材２０ａ、２０ｂの固定で補いつつ確保することができる。 The thin portion 38 is formed on the entire inner surface of the short straight tube portion 31 to which the fixing member 20a is attached. In the first embodiment, the fixing member 20a is disposed so as to be adjacent to the fixing member 20b at a relatively narrow interval, so that it is necessary even if the thin portion 38 is formed on the entire inner surface of the short straight pipe portion 31. It is possible to ensure a sufficient strength by supplementing the fixing members 20a and 20b.
　尚、短いストレート管部３１は、可撓管部２８、２９の間に位置する短い部分であることから、この内面全体に薄肉部３８を形成すれば、可撓管部２８、２９との肉厚変化をなくすことができる。その結果、成形状態の安定化や成形に係る装置の制御を簡易化することができるという効果を奏する。 In addition, since the short straight pipe part 31 is a short part located between the flexible pipe parts 28 and 29, if the thin part 38 is formed in this whole inner surface, it will be the wall | membrane with the flexible pipe parts 28 and 29. Thickness change can be eliminated. As a result, it is possible to stabilize the molding state and simplify the control of the apparatus related to the molding.
　薄肉部３９は、固定部材２０ｂが取り付けられる位置に合わせて形成される。薄肉部３９は、断面視でテーパ状になるような状態にて肉厚が薄くなり、最終的には可撓管部２９と同じ肉厚になるように形成される。薄肉部３９は、短い範囲で形成される。 The thin portion 39 is formed in accordance with the position where the fixing member 20b is attached. The thin-walled portion 39 is formed to have a thin thickness in a state where the thin-walled portion 39 is tapered in a sectional view, and finally has the same thickness as the flexible tube portion 29. The thin portion 39 is formed in a short range.
　薄肉部４０は、固定部材２０ｃ、２０ｄが取り付けられる位置に合わせて形成される。薄肉部４０は、断面視でテーパ状になるような状態にて肉厚が薄くなり、最終的には可撓管部３０と同じ肉厚になるように形成される。薄肉部４０は、薄肉部３９よりも長い範囲で形成される。 The thin portion 40 is formed in accordance with the position where the fixing members 20c and 20d are attached. The thin-walled portion 40 is formed so as to be thin in a state where the thin-walled portion 40 is tapered in a sectional view, and finally to have the same thickness as the flexible tube portion 30. The thin portion 40 is formed in a range longer than the thin portion 39.
　長いストレート管部３２は、この端部に薄肉部３９、４０が配置形成される。尚、端部を除く中間は本第１実施形態では薄肉に形成されないものとする。これは長いストレート管部３２が本第１実施形態において車両床下１１に配策される部分になり、そのため外装部材２４としての強度を十分に確保する必要があるからである。また、固定部材２０ｂと固定部材２０ｃとの間隔が大きくなることから、これらの固定だけでは仮に外力が加わった場合に、上記中間への負担が大きくなってしまうからである。 The long straight tube portion 32 is formed with thin portions 39 and 40 at this end portion. It is assumed that the middle except for the end portion is not formed thin in the first embodiment. This is because the long straight pipe portion 32 is a portion arranged under the vehicle floor 11 in the first embodiment, and therefore it is necessary to sufficiently ensure the strength as the exterior member 24. In addition, since the interval between the fixing member 20b and the fixing member 20c is increased, if the external force is applied only by these fixings, the intermediate load is increased.
　本第１実施形態では、可撓管部２８～３０に固定部材２０を取り付けてないが、外装部材２４としての強度を確保することができれば、部分的に薄肉に形成して軽量化を図ってもよいものとする。 In the first embodiment, the fixing member 20 is not attached to the flexible tube portions 28 to 30. However, if the strength as the exterior member 24 can be ensured, it is partially formed thin to reduce the weight. It shall be good.

　導体は、銅や銅合金、或いはアルミニウムやアルミニウム合金により製造される。導体に関しては、素線を撚り合わせてなる導体構造のものや、断面矩形又は丸形となる棒状の導体構造（例えば平角単心や丸単心となる導体構造であり、この場合、電線自体も棒状となる）のもののいずれであってもよいものとする。以上のような導体は、この外面に絶縁性の樹脂材料からなる絶縁体が押出成形される。 The conductor is made of copper or copper alloy, or aluminum or aluminum alloy.

The shield member is formed to have substantially the same length as the entire length of the high-voltage electric wire. The end of the shield member is connected to a shield case or the like (not shown) of the inverter unit 4 (see FIG. 1A) via the shield connector 14 (see FIG. 1A). As the shield member, for example, a conductive metal foil or a member including this metal foil may be adopted as long as it is possible to take countermeasures against electromagnetic waves. Moreover, you may assemble | attach in the state which forms and winds in a sheet form.
　固定部材２０（２０ａ～２０ｄ）は、本第１実施形態において公知のクランプであり、管体取付部４１と、車体固定部４２とを有する。管体取付部４１は、固定部材取付部３５の着脱部３７に取り付けられる部分であって、二つ割り構造を有するように形成される。車体固定部４２は、管体取付部４１に一体化する片持ち形状の部分に形成される。固定部材２０は、車体固定部４２に挿通されたボルト・ナット４３により固定される。尚、固定部材２０と同様の機能部分を外装部材２４の外面に一体形成して代替するようにしてもよい。 The fixing member 20 (20a to 20d) is a known clamp in the first embodiment, and includes a tube mounting portion 41 and a vehicle body fixing portion.

Note that the same functional portion as that of the fixing member 20 may be integrally formed on the outer surface of the exterior member 24 and replaced.
　上記構成及び構造において、ワイヤハーネス９は次のような手順で製造される。すなわち、ワイヤハーネス９は、高圧導電路２５を外装部材２４に挿通し、この後に高圧導電路２５の端部にそれぞれシールドコネクタ１４を設けることにより製造される。また、ワイヤハーネス９は、外装部材２４の固定部材取付部３５に固定部材２０（２０ａ～２０ｄ）を取り付けることにより製造される。尚、グロメットやブーツである止水部材２１、２２は予め組み付けられるものとする。 In the above configuration and structure, the wire harness 9 is manufactured by the following procedure.

And connector 123 provided at both ends).
　先ず、外装部材１２０について説明をする。
　図６及び図７において、外装部材１２０は、エアブロー方式又はバキューム方式による装置を用いた樹脂成形にて一本の真っ直ぐな管体形状のものに形成される（使用前は真っ直ぐである）。このような外装部材１２０には、可撓性を有する可撓管部１２４と、ストレートに配索する部分としてのストレート管部１２５とが形成される。可撓管部１２４とストレート管部１２５は、複数形成される。また、これらは交互に配置される。 First, the exterior member 120 will be described.
6 and 7, the exterior member 120 is formed into a single straight tube shape by resin molding using an air blow type or vacuum type device (it is straight before use). Such an exterior member 120 is formed with a flexible tube portion 124 having flexibility and a straight tube portion 125 as a portion to be installed straight. A plurality of flexible tube portions 124 and straight tube portions 125 are formed. Moreover, these are arrange | positioned alternately.
　可撓管部１２４は、車両取付形状（ワイヤハーネス配索先の形状。固定対象の形状）に合わせた位置に配置される。また、可撓管部１２４は、車両取付形状に合わせた長さにも形成される。可撓管部１２４の長さは一定でなく、車両取付形状に合わせて必要な長さでそれぞれ形成される。このような可撓管部１２４は、ワイヤハーネス１０９の梱包状態や輸送時、車両への経路配索時に、それぞれ所望の角度で撓ませられる（図７の仮想線で示す曲げ形状を参照）。可撓管部１２４は、撓ませて曲げ形状にすることができるとともに、図示のような真っ直ぐな元の状態（樹脂成形時の状態）に戻すことも当然にできるように形成される。 The flexible tube portion 124 is disposed at a position that matches the vehicle mounting shape (the shape of the wire harness wiring destination, the shape to be fixed). Moreover, the flexible tube part 124 is also formed in the length matched with the vehicle attachment shape. The length of the flexible tube portion 124 is not constant, and is formed with a necessary length according to the vehicle mounting shape. Such a flexible tube portion 124 is bent at a desired angle when the wire harness 109 is packed, transported, or routed to the vehicle (see the bent shape shown by the phantom line in FIG. 7). The flexible tube portion 124 can be bent to have a bent shape, and is naturally formed so as to be able to return to a straight original state as illustrated (a state at the time of resin molding).
　可撓管部１２４は、本第２実施形態において蛇腹管形状に形成される（可撓性を有すれば形状は特に限定されない）。具体的には、周方向の蛇腹凹部１２６及び蛇腹凸部１２７を有するとともに、これら蛇腹凹部１２６及び蛇腹凸部１２７が管軸方向に交互に連続するように形成される。可撓管部１２４は、特に図示しないが内面も蛇腹凹部及び蛇腹凸部を有し、ストレート管部１２５よりも薄肉に形成される。 The flexible tube portion 124 is formed in a bellows tube shape in the second embodiment (the shape is not particularly limited as long as it has flexibility). Specifically, the bellows concave portion 126 and the bellows convex portion 127 in the circumferential direction are formed, and the bellows concave portion 126 and the bellows convex portion 127 are formed alternately and continuously in the tube axis direction. Although not shown, the flexible tube portion 124 also has a bellows concave portion and a bellows convex portion, and is formed thinner than the straight tube portion 125.
　図６～図８において、ストレート管部１２５は、可撓管部１２４のような可撓性を持たない部分として形成される。また、ストレート管部１２５は、梱包状態や輸送時、経路配索時において曲がらない部分としても形成される（曲がらない部分とは、可撓性を積極的に持たせない部分という意味である）。ストレート管部１２５は、長く真っ直ぐのびた管体形状に形成される。 6 to 8, the straight tube portion 125 is formed as a non-flexible portion like the flexible tube portion 124. Further, the straight pipe portion 125 is also formed as a portion that does not bend when packed, transported, or routed (the portion that does not bend means a portion that does not actively have flexibility). . The straight tube portion 125 is formed in a long and straight tube shape.
　引用符号１２８は、ストレート管部１２５の内面を示す（図８参照）。また、引用符号１２９はストレート管部１２５の外面を示す。外面１２９は、溝部１３０を複数有して凹凸のある形状に形成される。 Reference numeral 128 indicates the inner surface of the straight pipe portion 125 (see FIG. 8). Reference numeral 129 indicates the outer surface of the straight pipe portion 125. The outer surface 129 has a plurality of groove portions 130 and is formed in an uneven shape.
　溝部１３０は、ストレート管部１２５の長手方向に沿って（管軸方向に沿って）等ピッチに配置形成される。ストレート管部１２５は、溝部１３０を複数有することから、溝部１３０以外の部分が恰も凸部１３１、１３２になるように形成される（凸部１３１、１３２は積極的に突出させた部分ではないものとする）。溝部１３０は、この深さが浅くなるように設定される。具体的には、ストレート管部１２５の外面１２９（凸部１３１、１３２の外面）に対し若干凹ませた程度の深さに設定される（溝部１３０の深さは、可撓管部１２４の蛇腹凹部１２６と比べると格段に浅くなるように形成される）。また、溝部１３０は、この幅が凸部１３１の幅の１／２程度になるように設定される。尚、凸部１３２の幅は、本第２実施形態において凸部１３１の幅よりも若干狭くなるように設定される（一例である）。溝部１３０の形成は任意である。 The grooves 130 are arranged and formed at an equal pitch along the longitudinal direction of the straight tube portion 125 (along the tube axis direction). Since the straight tube portion 125 has a plurality of groove portions 130, the portions other than the groove portion 130 are formed so that the ridges 131 and 132 are the ridges (the protrusions 131 and 132 are not positively protruded portions). And). The groove part 130 is set so that this depth becomes shallow. Specifically, it is set to a depth that is slightly recessed with respect to the outer surface 129 of the straight tube portion 125 (the outer surfaces of the convex portions 131 and 132) (the depth of the groove portion 130 is the bellows of the flexible tube portion 124). It is formed so as to be much shallower than the recess 126). Further, the groove portion 130 is set so that the width thereof is about ½ of the width of the convex portion 131. Note that the width of the convex portion 132 is set to be slightly narrower than the width of the convex portion 131 in the second embodiment (an example). The formation of the groove 130 is arbitrary.
　ストレート管部１２５には、本第２実施形態の特徴部分になる矢印１３３（印）が複数形成される。この矢印１３３は、本第２実施形態において、略「Ｌ」字状となる対称形状に形成される（線対称になる形状が好ましい。上記以外では「←」や「△」などが挙げられる）。矢印１３３は、視認のための印であって、ワイヤハーネス１０９の配策に係る方向性が分かるような部分として形成される。矢印１３３は、可撓管部１２４とストレート管部１２５との境界部分近傍に配置形成される。 A plurality of arrows 133 (marks) that are characteristic portions of the second embodiment are formed in the straight pipe portion 125. In the second embodiment, the arrow 133 is formed in a symmetrical shape that is substantially “L” -shaped (preferably a shape that is line-symmetric. Other than the above, “←”, “Δ”, etc. may be mentioned) . An arrow 133 is a mark for visual recognition, and is formed as a portion where the directionality related to the routing of the wire harness 109 can be understood. The arrow 133 is arranged and formed in the vicinity of the boundary portion between the flexible tube portion 124 and the straight tube portion 125.
　具体的には、図６及び図７に示す如く、可撓管部１２４の右隣の側で上記境界部分から一番近い凸部１３１及び二番目に近い凸部１３１の各外面に配置形成される（可撓管部１２４の左隣には存在しない）。また、矢印１３３は、ストレート管部１２５の管軸１３４（図８参照）に対し軸対称になるように配置形成される。本第２実施形態の矢印１３３は、上記境界部分近傍に２×２の合計４つで存在するように形成される（「Ｌ」「Ｌ」が１８０度反対側にも存在する）。尚、矢印１３３の数や配置は一例であるが、ワイヤハーネス１０９の配策作業において矢印１３３が視認できることが必要最低限の条件である。 Specifically, as shown in FIG. 6 and FIG. 7, it is arranged and formed on each outer surface of the convex portion 131 closest to the boundary portion and the second convex portion 131 on the right side of the flexible tube portion 124. (It does not exist on the left side of the flexible tube portion 124). Moreover, the arrow 133 is arranged and formed so as to be axially symmetric with respect to the tube axis 134 (see FIG. 8) of the straight tube portion 125. The arrows 133 of the second embodiment are formed so as to exist in a total of 2 × 2 in the vicinity of the boundary portion (“L” and “L” are also on the opposite side of 180 degrees). In addition, although the number and arrangement | positioning of the arrow 133 are an example, it is the minimum necessary conditions that the arrow 133 can be visually recognized in the routing work of the wire harness 109.
　矢印１３３は、凸部１３１の外面（ストレート管部１２５の外面１２９）から突出する形状に形成される。また、矢印１３３は、上記突出に伴いストレート管部１２５の内面１２８も追従して凹む形状に形成される。矢印１３３の突出に関する条件としては、視認できることである。これは、当然であるが、低すぎると視認性が悪くなるからである。また、矢印１３３の突出に関する条件としては、可撓管部１２４の蛇腹凸部１２７よりも低くすることである。これは、外装部材１２０の外径を太くしないためであり、三次元的な複雑なスペースであってもワイヤハーネス１０９の配策性を確保するためである。尚、高すぎると樹脂成形時に金型から抜けなくなる虞がある。 The arrow 133 is formed in a shape protruding from the outer surface of the convex portion 131 (the outer surface 129 of the straight tube portion 125). In addition, the arrow 133 is formed in a shape in which the inner surface 128 of the straight pipe portion 125 follows and is recessed along with the protrusion. The condition regarding the protrusion of the arrow 133 is that it can be visually recognized. Of course, this is because the visibility becomes poor if it is too low. Further, the condition regarding the protrusion of the arrow 133 is to make it lower than the bellows convex portion 127 of the flexible tube portion 124. This is because the outer diameter of the exterior member 120 is not increased, and the wire harness 109 is secured even in a three-dimensional complicated space. In addition, when too high, there exists a possibility that it may not come out of a metal mold | die at the time of resin molding.
　そして、矢印１３３の重要な条件としては、上記の如く内面１２８を凹ませることでストレート管部１２５の管軸１３４からの距離をｒ１からｒ２に増やして（ｒ１＜ｒ２）断面二次モーメントを大きくすることである。これは、断面二次モーメントを考慮して矢印１３３を形成することで、樹脂成形上、例えば肉厚ｔ１よりも肉厚ｔ２の方が若干薄くなった（ｔ１＞ｔ２）としても剛性の低下につながらないようにすることができるからである。結果、外装部材１２０としての機能を維持することができるからである。 As an important condition of the arrow 133, the inner surface 128 is recessed as described above to increase the distance from the tube axis 134 of the straight tube portion 125 from r1 to r2 (r1 <r2), thereby increasing the sectional moment of inertia. It is to be. This is because, by forming the arrow 133 in consideration of the secondary moment of section, the rigidity t is reduced even if the thickness t2 is slightly thinner than the thickness t1, for example, on the resin molding (t1> t2). This is because it can be prevented from being connected. As a result, the function as the exterior member 120 can be maintained.
　ここで、具体的な数値を挙げて矢印１３３について説明をする。矢印１３３の視認性は、ストレート管部１２５の外径がΦ１９（サイズＤ１９）の場合、外面１２９からの突出高さが０．３ｍｍ～０．６ｍｍの範囲で良好になることが分かった。また、矢印１３３の成形性は、上記突出高さが３ｍｍ以下であれば型抜きできることが分かった。これにより、視認性が良好になる突出高さ（すなわち、０．３ｍｍ～０．６ｍｍの範囲）であれば成形性が確保できることが分かった。断面二次モーメントに関しては、Φ１９でｔ１＝０．８ｍｍ、ｔ２＝０．７４ｍｍの場合、矢線Ｈの方向で２８３５ｍｍ４、矢線Ｖの方向で２９６０ｍｍ４になる。ちなみに、矢印１３３を形成しない単なる断面丸形状では２８３１ｍｍ４になる。肉厚ｔ１よりも肉厚ｔ２の方が若干薄くなったとしても剛性の低下につながらないようにすることができる。尚、サイズＤ１９以外に、サイズＤ７やＤ１３等でもよいのは勿論である。 Here, the arrow 133 will be described with specific numerical values. It has been found that the visibility of the arrow 133 is good when the projecting height from the outer surface 129 is in the range of 0.3 mm to 0.6 mm when the outer diameter of the straight tube portion 125 is Φ19 (size D19). Further, it was found that the moldability of the arrow 133 can be removed when the protruding height is 3 mm or less. Thus, it was found that the moldability can be ensured if the protrusion height (that is, in the range of 0.3 mm to 0.6 mm) at which the visibility is good. Regarding the moment of inertia of the cross section, when Φ19 is t1 = 0.8 mm and t2 = 0.74 mm, it is 2835 mm 4 in the direction of the arrow H and 2960 mm 4 in the direction of the arrow V. By the way, it is 2831 mm 4 in a simple cross-sectional shape that does not form the arrow 133. Even if the wall thickness t2 is slightly thinner than the wall thickness t1, it is possible to prevent the rigidity from being lowered. Of course, size D7, D13, etc. may be used in addition to size D19.
　矢印１３３は、上記数値から分かるように、この形成によって外装部材１２０としての機能を低下させることがなく、従ってワイヤハーネス１０９の配策に係る方向性を作業者に分からせるようにするためには有効な部分であると言える。 As can be seen from the above numerical values, the arrow 133 does not deteriorate the function as the exterior member 120 by this formation, and therefore, in order to make the operator understand the directionality related to the routing of the wire harness 109. It can be said that it is an effective part.
　尚、矢印１３３によってこれ以外の部分の成形性を損なうことはない。これは、仮にストレート管部１２５の内面１２８を凹ませずに肉盛りのみによって対応した場合（外面１２９に肉厚アップの部分を追加形成した場合）と比べると、肉厚差によるヒケ等の不具合を引き起こす虞がないからである。 It should be noted that the moldability of the other parts is not impaired by the arrow 133. This is a problem such as a sink due to a difference in thickness compared to a case where only the build-up of the inner surface 128 of the straight pipe portion 125 is not depressed (when an increased thickness portion is additionally formed on the outer surface 129). It is because there is no possibility of causing.
　図６及び図７において、ストレート管部１２５は、可撓管部１２４と比べ、リジッドな部分に形成される。ストレート管部１２５は、車両取付形状に合わせた位置や長さに形成される。複数のストレート管部１２５のうち特に図示しないが最も長尺なものは、車両床下１１１（図５参照）に配置されるように形成される。 6 and 7, the straight tube portion 125 is formed in a rigid portion as compared with the flexible tube portion 124. The straight pipe portion 125 is formed in a position and a length according to the vehicle mounting shape. Among the plurality of straight pipe portions 125, although not shown in particular, the longest one is formed so as to be arranged under the vehicle floor 111 (see FIG. 5).
　次に、以上のような外装部材１２０に収容保護される高圧導電路１２１について説明をする。
　高圧導電路１２１は、二本の高圧電線１３５と、この二本の高圧電線１３５を覆うシールド部材１３６とを備えて構成される（一例である。例えば更にシースを含んで構成してもよい）。 Next, the high voltage conductive path 121 accommodated and protected by the exterior member 120 will be described.
The high-voltage conductive path 121 includes two high-voltage electric wires 135 and a shield member 136 that covers the two high-voltage electric wires 135 (this is an example. For example, the sheath may further include a sheath). .
　高圧電線１３５は、導体と、この導体を被覆する絶縁体とを備えて構成される。高圧電線１３５は、電気的な接続に必要な長さを有して形成される。高圧電線１３５は、ワイヤハーネス１０９がインバータユニット１０４とバッテリー１０５（ジャンクションブロック１１２。図５の（ａ）参照）とを電気的に接続することから、長尺なものに形成される。 The high voltage electric wire 135 includes a conductor and an insulator covering the conductor. The high voltage electric wire 135 is formed to have a length necessary for electrical connection. The high-voltage electric wire 135 is formed in a long shape because the wire harness 109 electrically connects the inverter unit 104 and the battery 105 (junction block 112; see FIG. 5A).
　導体は、銅や銅合金、或いはアルミニウムやアルミニウム合金により製造される。導体に関しては、素線を撚り合わせてなる導体構造のものや、断面矩形又は丸形となる棒状の導体構造（例えば平角単心や丸単心となる導体構造であり、この場合、電線自体も棒状となる）のもののいずれであってもよいものとする。以上のような導体は、この外面に絶縁性の樹脂材料からなる絶縁体が押出成形される。 The conductor is made of copper or copper alloy, or aluminum or aluminum alloy. Concerning the conductor, a conductor structure in which strands are twisted together or a rod-shaped conductor structure having a rectangular or round cross section (for example, a conductor structure having a flat single core or a round single core. It may be any of those that are rod-shaped). In the conductor as described above, an insulator made of an insulating resin material is extruded on the outer surface.
　尚、高圧電線１３５として、本第２実施形態では公知のものを採用するが、この限りでないものとする。すなわち、公知のバスバーに絶縁体を設けて高圧回路としたもの等を採用してもよい。 In addition, although a well-known thing is employ | adopted as the high voltage electric wire 135 in this 2nd Embodiment, it shall not be this limitation. That is, a known bus bar provided with an insulator to form a high voltage circuit may be employed.
　絶縁体は、熱可塑性樹脂材料を用いて導体の外周面に押出成形される。絶縁体は、断面円形状の被覆として形成される。絶縁体は、所定の厚みを有して形成される。上記熱可塑性樹脂としては、公知の様々な種類のものが使用可能であり、例えばポリ塩化ビニル樹脂やポリエチレン樹脂、ポリプロピレン樹脂などの高分子材料から適宜選択される。 The insulator is extruded on the outer peripheral surface of the conductor using a thermoplastic resin material. The insulator is formed as a cover having a circular cross section. The insulator is formed with a predetermined thickness. As the thermoplastic resin, various known types can be used, and are appropriately selected from polymer materials such as polyvinyl chloride resin, polyethylene resin, and polypropylene resin.
　シールド部材１３６は、二本の高圧電線１３５を一括して覆う電磁シールド用の部材（電磁波対策用のシールド部材）であって、多数の素線を筒状に編んでなる公知の編組が採用される。シールド部材１３６は、二本の高圧電線１３５の全長とほぼ同じ長さに形成される。シールド部材１３６は、この端部が上記シールドコネクタ１１４（図５の（ａ）参照）を介してインバータユニット１０４（図５の（ａ）参照）のシールドケース等（図示省略）に接続される。尚、シールド部材１３６は、電磁波対策をすることが可能であれば、例えば導電性を有する金属箔や、この金属箔を含む部材を採用してもよい。また、シート状に形成して巻き付けるような状態で組み付けてもよい。 The shield member 136 is an electromagnetic shielding member (shielding member for electromagnetic wave countermeasures) that collectively covers the two high-voltage electric wires 135, and a known braid formed by knitting a large number of strands into a cylindrical shape is adopted. The The shield member 136 is formed to have substantially the same length as the entire length of the two high-voltage electric wires 135. The end of the shield member 136 is connected to a shield case or the like (not shown) of the inverter unit 104 (see FIG. 5A) via the shield connector 114 (see FIG. 5A). Note that the shield member 136 may employ, for example, a conductive metal foil or a member including this metal foil as long as it can take countermeasures against electromagnetic waves. Moreover, you may assemble | attach in the state which forms and winds in a sheet form.
　以上、図５～図８を参照しながら説明してきたように、本第２実施形態に係る外装部材１２０によれば、内面１２８を凹ませ且つ外面１２９を突出させた形状の矢印１３３を有することから、ワイヤハーネス１０９を車両へ配策する際に矢印１３３を見て確認することで逆付けを防止することができるという効果を奏する。 As described above with reference to FIGS. 5 to 8, the exterior member 120 according to the second embodiment has the arrow 133 having a shape in which the inner surface 128 is recessed and the outer surface 129 protrudes. Thus, there is an effect that reverse attachment can be prevented by checking the arrow 133 when checking the wiring harness 109 to the vehicle.

（第３実施形態） Hereinafter, with reference to drawings, the electric wire protection tube concerning a 3rd embodiment of the present invention is explained in detail.
(Third embodiment)

　本発明の第３実施形態に係る電線保護チューブ２０１は、例えば、自動車の内部に配索するワイヤハーネスＷＨの電線束Ｗｂを保護するものである。 FIG. 9A is a view showing the periphery of the branch cylinder portion 220 of the wire protection tube 201 according to the third embodiment of the present invention, and FIG. 9B is a cross-sectional view of the wire protection tube 201 shown in FIG. It is the figure which showed the wire harness WH containing the electric wire protection tube 201 and the electric wire bundle Wb in the electric wire protection tube 201 by having shown by. FIG. 10 is a perspective view of the electric wire protection tube 201 shown in FIG. FIG. 11 is a view showing a cross section around the branch cylinder part 220 of the electric wire protection tube 201 and the electric wire W. FIG. 11A shows a state before the electric wire W contacts the edge 220c of the branch cylinder part 220. (B) is the figure after the electric wire W contacted the edge 220c of the branch cylinder part 220, and showed the state.
The wire protection tube 201 according to the third embodiment of the present invention protects, for example, the wire bundle Wb of the wire harness WH routed inside the automobile.
　電線保護チューブ２０１は、合成樹脂等の絶縁材からなり、幹線Ｗ１と、幹線Ｗ１から分岐する支線Ｗ２とを有する電線束Ｗｂの幹線Ｗ１の外周を覆う幹線筒部２１０と、電線束Ｗｂの分岐部分の支線Ｗ２の外周を覆うように幹線筒部２１０から分岐する分岐筒部２２０を有する。 The electric wire protection tube 201 is made of an insulating material such as synthetic resin, and has a main tube portion 210 covering the outer periphery of the main wire W1 of the electric wire bundle Wb having the main wire W1 and a branch line W2 branched from the main wire W1, and a branch of the electric wire bundle Wb. It has the branch cylinder part 220 branched from the trunk line cylinder part 210 so that the outer periphery of the partial branch line W2 may be covered.
　幹線筒部２１０は、軸方向に沿って山状部分と谷状部分とを交互に形成した蛇腹形状を有し、電線束Ｗｂの配索経路に合わせて屈曲自在な形状に形成されている。
　また、幹線筒部２１０は、軸方向に沿って一方端から他方端に延びるスリット２１１が形成され、このスリット２１１から電線保護チューブ２０１内に電線束Ｗｂが収容されるようになっている。 The main tube portion 210 has a bellows shape in which mountain-shaped portions and valley-shaped portions are alternately formed along the axial direction, and is formed in a shape that can be bent in accordance with the routing route of the wire bundle Wb.
Further, the main tube portion 210 is formed with a slit 211 extending from one end to the other end along the axial direction, and the wire bundle Wb is accommodated in the wire protection tube 201 from the slit 211.
　分岐筒部２２０は、分岐方向に向けて突出するように幹線筒部２１０と一体的に設けられ、かつ、弾性的に屈曲自在な屈曲自在部２３０が分岐筒部２２０の開口２２０ａ側の端部２２１の周方向に沿って設けられている。
　この分岐筒部２２０は、幹線筒部２１０に対して略直方向に突出するように設けられている。 The branch tube portion 220 is provided integrally with the main tube portion 210 so as to protrude in the branch direction, and the bendable portion 230 that is elastically bendable is the end of the branch tube portion 220 on the opening 220a side. It is provided along the circumferential direction of 221.
The branch tube portion 220 is provided so as to protrude in a substantially straight direction with respect to the main tube portion 210.
　また、分岐筒部２２０は、軸方向で筒内径が変化するように、基端側に筒内径を小さくして設けた小径筒部２２２と、開口端側に該小径筒部２２２に比して筒内径を大きくして設けた大径筒部２２３とを有する。 Further, the branch cylinder part 220 has a small-diameter cylinder part 222 provided on the base end side with a small cylinder inner diameter so that the cylinder inner diameter changes in the axial direction, and an opening end side compared to the small-diameter cylinder part 222. A large-diameter cylindrical portion 223 provided with a large cylindrical inner diameter.
　屈曲自在部２３０は、小径筒部２２２から大径筒部２２３に筒内径が大きく変化するように軸方向から径外方向に屈曲された分岐筒部２２０の壁である。より具体的には、屈曲自在部２３０は、軸方向から径外方向に略直角に屈曲された分岐筒部２２０の壁である。 The bendable part 230 is a wall of the branch cylinder part 220 that is bent from the axial direction to the radially outward direction so that the cylinder inner diameter changes greatly from the small diameter cylinder part 222 to the large diameter cylinder part 223. More specifically, the bendable part 230 is a wall of the branch cylinder part 220 that is bent substantially perpendicularly from the axial direction to the radially outward direction.
　このような電線保護チューブ２０１は、電線Ｗが、分岐筒部２２０の開口端縁面２２０ｂのエッジ２２０ｃに接触した場合、図１１の（ｂ）に示すように、エッジ２２０ｃが電線Ｗを押圧する力を軽減するように屈曲自在部２３０が弾性的に屈曲するように構成されている。 In such an electric wire protection tube 201, when the electric wire W comes into contact with the edge 220c of the opening end surface 220b of the branch tube portion 220, the edge 220c presses the electric wire W as shown in FIG.

　まず、電線保護チューブ製造ライン３００について説明する。
　電線保護チューブ製造ライン３００は、図１２中、左側が上流側となり、左から右に向けて並んで配置された、樹脂押出部３１０と、樹脂成形部３２０と、切断スリット加工部３３０と、張力調整部３４０と、受取部３５０と、によって加工処理が順次施されるようになっている。 First, the wire protection tube production line 300 will be described.
In the wire protection tube manufacturing line 300, the left side is the upstream side in FIG. 12, and the resin extrusion unit 310, the resin molding unit 320, the cutting slit processing unit 330, and the tension are arranged side by side from left to right. Processing is sequentially performed by the adjusting unit 340 and the receiving unit 350.
　樹脂押出部３１０は、電線保護チューブ２０１の材料となる樹脂を樹脂成形部３２０に連続的に供給する部分である。 The resin extruding part 310 is a part that continuously supplies the resin as the material of the wire protection tube 201 to the resin molding part 320.
　樹脂成形部３２０は、樹脂押出部３１０よって供給された樹脂を、図１３に示すような成形用の上金型３２１および下金型３２２によって電線保護チューブ２０１の中間部材２０１Ａを成形する部分である。
　この樹脂成形部３２０は、複数の上金型３２１および下金型３２２のそれぞれを環状、かつ成形位置で対向するように配置することによって樹脂押出部３１０から供給される樹脂を連続的に成形する。 The resin molding part 320 is a part for molding the intermediate member 201A of the wire protection tube 201 by using the upper mold 321 and the lower mold 322 for molding the resin supplied by the resin extrusion part 310 as shown in FIG. .
The resin molding unit 320 continuously molds the resin supplied from the resin extrusion unit 310 by disposing each of the plurality of upper molds 321 and lower molds 322 in an annular shape and facing each other at the molding position. .
　上下金型３２１、３２２は、分岐筒部２２０の小径筒部２２２と、大径筒部２２３とにそれぞれ対応したキャビティーを有し、これによって屈曲自在部２３０を成形するように構成されている。
　また、上下金型３２１、３２２は、分岐筒部２２０の開口２２０ａが閉じた中間部材２０１Ａを成形するように構成されているため、開口２２０ａに対応する部分を閉じしたキャビティーにすることができるように構成されている。
　このため、屈曲自在部２３０を含めた分岐筒部２２０の外郭を幹線筒部２１０の外郭とともに上下金型３２１、３２２によって閉じられたキャビティーによって一体的に成形し易いように構成されている。 The upper and lower molds 321 and 322 have cavities respectively corresponding to the small-diameter cylindrical portion 222 and the large-diameter cylindrical portion 223 of the branch cylindrical portion 220, and are configured to mold the bendable portion 230. .
Further, since the upper and lower molds 321 and 322 are configured to mold the intermediate member 201A in which the opening 220a of the branch cylinder part 220 is closed, the cavity corresponding to the opening 220a can be a closed cavity. It is configured as follows.
Therefore, the outer shell of the branch tube portion 220 including the bendable portion 230 is configured to be easily molded integrally with the outer shell of the trunk tube portion 210 by the cavities closed by the upper and lower molds 321 and 322.
　切断スリット加工部３３０は、樹脂成形部３２０によって供給された中間部材２０１Ａに対して、スリット２１１を形成するとともに、分岐筒部２２０の先端部２２１ａを切断することによって開口２２０ａを形成する部分である。
　この切断スリット加工部３３０は、図１４の（ｂ）に示すように、スリット２１１を形成するためのカッターであるスリット形成用カッター２１３１と、分岐筒部２２０の先端部２２１ａを切断するためのカッターである分岐部端部切断用カッター３３２と、を有する。
　このような切断スリット加工部３３０は、中間部材２０１Ａが搬送方向Ｄに移動することによって、スリット形成用カッター３３１がスリット２１１を形成するとともに、分岐部端部切断用カッター３３２が先端部２２１ａを切断することによって開口２２０ａを形成する。 The cutting slit processing part 330 is a part that forms the slit 211 in the intermediate member 201A supplied by the resin molding part 320 and forms the opening 220a by cutting the tip part 221a of the branch cylinder part 220. .
As shown in FIG. 14B, the cutting slit processing portion 330 includes a slit forming cutter 2131 that is a cutter for forming the slit 211, and a cutter for cutting the distal end portion 221 a of the branch cylindrical portion 220. And a branch portion end cutting cutter 332.
In such a cutting slit processing portion 330, the slit forming cutter 331 forms the slit 211 as the intermediate member 201A moves in the transport direction D, and the branch end cutting cutter 332 cuts the tip 221a. Thus, the opening 220a is formed.
　張力調整部３４０は、切断スリット加工部３３０と受取部３５０との間の電線保護チューブ２０１の張力を調整する部分である。 The tension adjusting unit 340 is a part that adjusts the tension of the electric wire protection tube 201 between the cutting slit processing unit 330 and the receiving unit 350.
　受取部３５０は、切断スリット加工部３３０によって加工し、幹線筒部２１０が連続的につながる電線保護チューブ２０１をドラム３５１に巻き取る部分である。このドラム３５１に巻き取った電線保護チューブ２０１は、ワイヤハーネスＷＨを製造する際に所定の長さに切断して使用する。 The receiving part 350 is a part that is processed by the cutting slit processing part 330 and winds up the electric wire protection tube 201 to which the main tube part 210 is continuously connected around the drum 351. The wire protection tube 201 wound around the drum 351 is cut into a predetermined length and used when the wire harness WH is manufactured.
　次に、図１５を用いて電線保護チューブ製造ライン３００によって電線保護チューブ２０１を製造する手順について説明する。
　まず、作業者は、樹脂押出部３１０に樹脂等の材量を投入し、電線保護チューブ製造ライン３００を起動する。すると樹脂成形部３２０が樹脂押出部３１０から供給された樹脂を上下金型３２１、３２２によって金型プレス成形する。これによって分岐筒部２２０の開口２２０ａを閉じた中間部材２０１Ａが成形される（図１５の（ａ）参照）。 Next, a procedure for manufacturing the wire protection tube 201 by the wire protection tube manufacturing line 300 will be described with reference to FIG.
First, the worker inputs a material amount such as resin into the resin extrusion unit 310 and activates the wire protection tube production line 300. Then, the resin molding unit 320 press-molds the resin supplied from the resin extrusion unit 310 by the upper and lower molds 321 and 322. Thus, an intermediate member 201A that closes the opening 220a of the branch tube portion 220 is formed (see FIG. 15A).
　その後、切断スリット加工部３３０が中間部材２０１Ａに対してスリット２１１および開口２２０ａを形成することによって電線保護チューブ２０１が完成する（図１５の（ｂ）および図１５の（ｃ）参照）。
　ここで、中間部材２０１Ａが搬送方向Ｄに移動することによって、スリット形成用カッター３３１が、図１４の（ａ）の仮想線Ｌ１に沿って中間部材２０１Ａに切り込まれることによって、スリット２１１を形成し、分岐部端部切断用カッター３３２が仮想線Ｌ２に沿って中間部材２０１Ａに切り込まれることによって、開口２２０ａを形成する。
　このようにして製造した電線保護チューブ２０１は、その後、受取部３５０に送られてドラム３５１単位で巻き取って保管される。 Thereafter, the cutting slit processing portion 330 forms the slit 211 and the opening 220a in the intermediate member 201A, thereby completing the wire protection tube 201 (see FIG. 15B and FIG. 15C).
Here, when the intermediate member 201A moves in the transport direction D, the slit forming cutter 331 is cut into the intermediate member 201A along the virtual line L1 in FIG. The branch end cutting cutter 332 is cut into the intermediate member 201A along the imaginary line L2, thereby forming the opening 220a.
The electric wire protection tube 201 manufactured in this way is then sent to the receiving part 350 and wound up and stored in units of the drum 351.
　本発明の第３実施形態に係る電線保護チューブ２０１は、分岐筒部２２０が分岐方向に向けて突出するように幹線筒部２１０と一体的に設けられているので、分岐部分のエッジを開口端縁面２２０ｂだけに絞りこみ、しかも、電線Ｗが分岐筒部２２０の開口端縁面２２０ｂのエッジ２２０ｃに接触すると、エッジ２２０ｃが電線Ｗを押圧する力を軽減するように屈曲自在部２３０が弾性的に屈曲するようになっているので、エッジ２２０ｃと電線Ｗとの擦れを防ぎ、結果的に、分岐部分によって電線Ｗが損傷することを防ぐことができる。 Since the electric wire protection tube 201 according to the third embodiment of the present invention is provided integrally with the trunk tube portion 210 so that the branch tube portion 220 protrudes in the branch direction, the edge of the branch portion is opened to the open end. When the electric wire W comes into contact with the edge 220c of the opening end edge surface 220b of the branch tube portion 220, the bendable portion 230 is elastic so as to reduce the force with which the edge 220c presses the electric wire W. Therefore, the edge 220c and the electric wire W can be prevented from rubbing, and as a result, the electric wire W can be prevented from being damaged by the branch portion.
　また、本第３実施形態に係る電線保護チューブ２０１は、分岐筒部２２０の筒内径を変化させることによって、屈曲自在部２３０が形成されるようにしているので、電線保護チューブ２０１が樹脂成形品である場合、金型によって容易に一体的に成形することができる。 Moreover, since the electric wire protection tube 201 which concerns on this 3rd Embodiment is made to form the flexible part 230 by changing the cylinder internal diameter of the branch cylinder part 220, the electric wire protection tube 201 is a resin molded product. In this case, it can be easily formed integrally with a mold.
（変形例１）
　次に、図１６を用いて本発明の第３実施形態に係る電線保護チューブ２０１の変形例１の電線保護チューブ２０２について説明する。
　図１６は、変形例１の電線保護チューブ２０２の分岐筒部２２０周辺の断面図である。
　この変形例１の電線保護チューブ２０２は、幹線筒部２４０の形状が異なる点で、上記第３実施形態の電線保護チューブ２０１と異なる。
　なお、その他の構成は上記第３実施形態の電線保護チューブ２０１と同様であり、上記第３実施形態と同一構成部分には同一符号を付している。 (Modification 1)
Next, the electric wire protection tube 202 of the modification 1 of the electric wire protection tube 201 which concerns on 3rd Embodiment of this invention is demonstrated using FIG.
FIG. 16 is a cross-sectional view of the periphery of the branch cylinder portion 220 of the wire protection tube 202 of the first modification.
The electric wire protection tube 202 of this modification 1 differs from the electric wire protection tube 201 of the said 3rd Embodiment by the point from which the shape of the trunk line cylinder part 240 differs.
In addition, the other structure is the same as that of the electric wire protection tube 201 of the said 3rd Embodiment, and the same code | symbol is attached | subjected to the same component as the said 3rd Embodiment.
　この変形例１の電線保護チューブ２０２は、図１６に示すように、幹線筒部２４０が直管形状をなしている。 In the electric wire protection tube 202 of the first modification, as shown in FIG. 16, the main tube portion 240 has a straight tube shape.
　この変形例１の電線保護チューブ２０２は、分岐方向に向けて突出するように幹線筒部２４０と一体的に設けられているので、分岐部分のエッジを開口端縁面２２０ｂだけに絞りこみ、しかも、電線Ｗが開口端縁面２２０ｂのエッジ２２０ｃに接触すると、エッジ２２０ｃが電線Ｗを押圧する力を軽減するように屈曲自在部２３０が弾性的に屈曲するようになっているので、上記第３実施形態の電線保護チューブ２０１と同様に、エッジ２２０ｃと電線Ｗとの擦れを防ぎ、結果的に、分岐部分によって電線Ｗが損傷することを防ぐことができる。 Since the electric wire protection tube 202 of this modification 1 is provided integrally with the trunk tube portion 240 so as to protrude in the branching direction, the edge of the branching portion is narrowed down only to the opening edge surface 220b, and When the electric wire W comes into contact with the edge 220c of the opening edge surface 220b, the bendable portion 230 is elastically bent so as to reduce the force with which the edge 220c presses the electric wire W. Similarly to the wire protection tube 201 of the embodiment, rubbing between the edge 220c and the wire W can be prevented, and as a result, the wire W can be prevented from being damaged by the branch portion.
（変形例２）
　次に、図１７を用いて本発明の第３実施形態に係る電線保護チューブ２０１の変形例２の電線保護チューブ２０３について説明する。
　図１７は、変形例２の電線保護チューブ２０３の分岐筒部２２０周辺の断面図である。
　この変形例２の電線保護チューブ２０３は、幹線筒部２５０の形状が異なる点で、上記第３実施形態の電線保護チューブ２０１と異なる。
　なお、その他の構成は上記第３実施形態の電線保護チューブ２０１と同様であり、上記第３実施形態と同一構成部分には同一符号を付している。 (Modification 2)
Next, the electric wire protection tube 203 of the modification 2 of the electric wire protection tube 201 which concerns on 3rd Embodiment of this invention is demonstrated using FIG.
FIG. 17 is a cross-sectional view of the periphery of the branch cylinder portion 220 of the wire protection tube 203 of the second modification.
The electric wire protection tube 203 of the second modified example is different from the electric wire protection tube 201 of the third embodiment in that the shape of the trunk tube portion 250 is different.
In addition, the other structure is the same as that of the electric wire protection tube 201 of the said 3rd Embodiment, and the same code | symbol is attached | subjected to the same component as the said 3rd Embodiment.
　この変形例２の電線保護チューブ２０３は、図１７に示すように、幹線筒部２５０が直管形状および蛇腹形状の両方を有している。 In the electric wire protection tube 203 of the second modification, as shown in FIG. 17, the main tube portion 250 has both a straight tube shape and an accordion shape.
　この変形例２の電線保護チューブ２０３は、上記第３実施形態の電線保護チューブ２０１と上記変形例１の電線保護チューブ２０２とを含む構成であるため、上記第３実施形態の電線保護チューブ２０１と同様に、エッジ２２０ｃと電線Ｗとの擦れを防ぎ、結果的に、分岐部分によって電線Ｗが損傷することを防ぐことができる。 Since the electric wire protection tube 203 of this modification 2 is the structure containing the electric wire protection tube 201 of the said 3rd Embodiment and the electric wire protection tube 202 of the said modification 1, the electric wire protection tube 201 of the said 3rd Embodiment and Similarly, rubbing between the edge 220c and the electric wire W can be prevented, and as a result, the electric wire W can be prevented from being damaged by the branch portion.
（変形例３）
　次に、図１８を用いて本発明の第３実施形態に係る電線保護チューブ２０１の変形例３の電線保護チューブ２０４について説明する。
　図１８は、変形例３の電線保護チューブ２０４の分岐筒部２６０周辺を示した図であり、電線保護チューブ２０４を断面で示すことによって電線保護チューブ２０４と、電線保護チューブ２０４内の電線束Ｗｂとを含むワイヤハーネスＷＨを示した図である。
　この変形例３の電線保護チューブ２０４は、分岐筒部２６０の形状が異なる点で、上記第３実施形態の電線保護チューブ２０１と異なる。
　なお、その他の構成は上記第３実施形態の電線保護チューブ２０１と同様であり、上記第３実施形態と同一構成部分には同一符号を付している。 (Modification 3)
Next, the electric wire protection tube 204 of the modification 3 of the electric wire protection tube 201 which concerns on 3rd Embodiment of this invention is demonstrated using FIG.
FIG. 18 is a view showing the periphery of the branch cylindrical portion 260 of the electric wire protection tube 204 of Modification 3. By showing the electric wire protection tube 204 in cross section, the electric wire protection tube 204 and the electric wire bundle Wb in the electric wire protection tube 204 are shown. It is the figure which showed the wire harness WH containing these.
The electric wire protection tube 204 of Modification 3 is different from the electric wire protection tube 201 of the third embodiment in that the shape of the branch tube portion 260 is different.
In addition, the other structure is the same as that of the electric wire protection tube 201 of the said 3rd Embodiment, and the same code | symbol is attached | subjected to the same component as the said 3rd Embodiment.
　分岐筒部２６０は、分岐方向に向けて突出するように幹線筒部２１０と一体的に設け、かつ、弾性的に屈曲自在な屈曲自在部２７０を分岐筒部２６０の開口２６０ａ側の端部２２１の周方向に沿って設けている。 The branch tube portion 260 is provided integrally with the main tube portion 210 so as to protrude in the branch direction, and an end portion 221 on the opening 260a side of the branch tube portion 260 is provided with a bendable portion 270 that is elastically bendable. It is provided along the circumferential direction.
　屈曲自在部２７０は、開口端縁面２６０ｂが径外方向に向くように分岐筒部２６０の壁を軸方向から径外方向に略直角に屈曲した部分である。 The bendable part 270 is a part where the wall of the branch cylinder part 260 is bent substantially perpendicularly from the axial direction to the radially outward direction so that the opening edge surface 260b faces the radially outward direction.
　この変形例３の電線保護チューブ２０４は、分岐筒部２６０を分岐方向に向けて突出するように幹線筒部２１０と一体的に設けているので、分岐部分のエッジを開口端縁面２２０ｂだけに絞りこみ、しかも、電線Ｗが分岐筒部２６０の開口端縁面２６０ｂのエッジ２６０ｃに接触すると、エッジ２６０ｃが電線Ｗを押圧する力を軽減するように屈曲自在部２７０が弾性的に屈曲するようになっているので、上記第３実施形態の電線保護チューブ２０１と同様に、エッジ２６０ｃと電線Ｗとの擦れを防ぎ、結果的に、分岐部分によって電線Ｗが損傷することを防ぐことができる。 Since the electric wire protection tube 204 of this modification 3 is provided integrally with the trunk tube portion 210 so that the branch tube portion 260 protrudes in the branch direction, the edge of the branch portion is only on the opening edge surface 220b. When the electric wire W comes into contact with the edge 260c of the opening end surface 260b of the branch tube portion 260, the bendable portion 270 is elastically bent so as to reduce the force with which the edge 260c presses the electric wire W. Therefore, like the wire protection tube 201 of the third embodiment, the edge 260c and the wire W can be prevented from rubbing, and as a result, the wire W can be prevented from being damaged by the branch portion.
（変形例４）
　次に、図１９を用いて本発明の第３実施形態に係る電線保護チューブ２０１の変形例４の電線保護チューブ２０５について説明する。
　図１９は、変形例４の電線保護チューブ２０５の分岐筒部２８０周辺を示した図であり、電線保護チューブ２０５を断面で示すことによって電線保護チューブ２０５と、電線保護チューブ２０５内の電線束Ｗｂとを含むワイヤハーネスＷＨを示した図である。
　この変形例４の電線保護チューブ２０５は、分岐筒部２８０の形状が異なる点で、上記第３実施形態の電線保護チューブ２０１と異なる。
　なお、その他の構成は上記第３実施形態の電線保護チューブ２０１と同様であり、上記第３実施形態と同一構成部分には同一符号を付している。 (Modification 4)
Next, the wire protection tube 205 of the modification 4 of the wire protection tube 201 which concerns on 3rd Embodiment of this invention is demonstrated using FIG.
FIG. 19 is a view showing the periphery of the branch cylinder portion 280 of the electric wire protection tube 205 of Modification 4. By showing the electric wire protection tube 205 in cross section, the electric wire protection tube 205 and the electric wire bundle Wb in the electric wire protection tube 205 are shown. It is the figure which showed the wire harness WH containing these.
The electric wire protection tube 205 of this modification 4 differs from the electric wire protection tube 201 of the said 3rd Embodiment by the point from which the shape of the branch cylinder part 280 differs.
In addition, the other structure is the same as that of the electric wire protection tube 201 of the said 3rd Embodiment, and the same code | symbol is attached | subjected to the same component as the said 3rd Embodiment.
　分岐筒部２８０は、分岐方向に向けて突出するように幹線筒部２１０と一体的に設け、かつ、弾性的に屈曲自在な屈曲自在部２３０を分岐筒部２８０の開口２８０ａ側の端部２８１の周方向に沿って設けている。
　より具体的には、分岐筒部２８０は、幹線筒部２１０に対して略直方向から傾いて突出するように設けている。 The branch tube portion 280 is provided integrally with the main tube portion 210 so as to protrude toward the branch direction, and an elastically bendable flexible portion 230 is provided at the end 281 on the opening 280a side of the branch tube portion 280. It is provided along the circumferential direction.
More specifically, the branch tube portion 280 is provided so as to protrude from the main tube portion 210 while being inclined from a substantially straight direction.
　この変形例４の電線保護チューブ２０５は、分岐筒部２８０を分岐方向に向けて突出するように幹線筒部２１０と一体的に設けているので、分岐部分のエッジを開口端縁面２８０ｂだけに絞りこみ、しかも、電線Ｗが分岐筒部２８０の開口端縁面２８０ｂのエッジ２８０ｃに接触すると、エッジ２８０ｃが電線Ｗを押圧する力を軽減するように屈曲自在部２３０が弾性的に屈曲するようになっているので、上記第３実施形態の電線保護チューブ２０１と同様に、エッジ２８０ｃと電線Ｗとの擦れを防ぎ、結果的に、分岐部分によって電線Ｗが損傷することを防ぐことができる。 Since the electric wire protection tube 205 of this modification 4 is provided integrally with the trunk tube portion 210 so that the branch tube portion 280 protrudes in the branch direction, the edge of the branch portion is only on the opening edge surface 280b. In addition, when the electric wire W comes into contact with the edge 280c of the opening end surface 280b of the branch tube portion 280, the bendable portion 230 is elastically bent so as to reduce the force with which the edge 280c presses the electric wire W. Therefore, similarly to the wire protection tube 201 of the third embodiment, the edge 280c and the wire W can be prevented from rubbing, and as a result, the wire W can be prevented from being damaged by the branch portion.
