　ところで、車両における電線の外装部材への要請としては、次の要請１～４が挙げられる。 By the way, the following requests 1 to 4 can be cited as requests for the exterior member of the electric wire in the vehicle.
　まず、要請１は、電線とその周辺部材が干渉した際に電線を保護することである。 First, Request 1 is to protect the electric wire when the electric wire and its peripheral members interfere.
　要請２は、電線とその周辺部材が干渉しないように、電線を経路規制することである。しかも、電線の配設経路は、直線部分と曲線部分とが組合わされていることが多く、そのような直線部分と曲線部分との複合的な配設経路でも、電線を経路規制できることが好ましい。 Request 2 is to restrict the route of the electric wire so that the electric wire and its peripheral members do not interfere with each other. Moreover, in many cases, the arrangement route of the electric wire is a combination of a straight portion and a curved portion, and it is preferable that the electric wire can be regulated even in a combined arrangement route of such a straight portion and a curved portion.
　要請３は、外装部材の製造コストが安価であることである。 Request 3 is that the manufacturing cost of the exterior member is low.
　要請４は、外装部材を車両に取付けるコストが安価であることである。特に、直線部分曲線部分との複合的な配設経路であっても、外装部材を低コストで車両に取付けられることが好ましい。 Request 4 is that the cost of attaching the exterior member to the vehicle is low. In particular, it is preferable that the exterior member can be attached to the vehicle at a low cost even in a complex arrangement route with the straight portion curve portion.
　上記要請１～４に鑑みて、背景技術１～４を検討する。 Considering the above requests 1 to 4, consider the background technologies 1 to 4.
　背景技術１では、要請３を満たすことは難しい。電線の配設経路が長い等の原因でプロテクタが大型化したり、強度上の都合からリブ形状を作り込むこと等が要因で形状が複雑化したりすれば、射出成形用金型コストが上昇し、また、射出成形機も高額になるからである。 In Background Technology 1, it is difficult to satisfy Request 3. If the size of the protector increases due to reasons such as the long wiring path, or if the shape becomes complicated due to the creation of a rib shape due to strength, etc., the mold cost for injection molding will increase. This is also because the injection molding machine is expensive.
　背景技術２では、要請２及び３を満たすことは難しい。まず、要請２に関しては、押出成形された角筒状のプロテクタは曲げることは困難であり、直線部分と曲線部分との複合的な配設経路でも、電線を経路規制することは困難である。また、要請３に関しては、押出成形された角筒状のプロテクタの適用箇所は、電線の配設経路の直線部分に限定されるため、結果として、電線の保護適用箇所に対する部品コストが相対的に大きくなってしまうからである。 In Background Art 2, it is difficult to satisfy requests 2 and 3. First, regarding request 2, it is difficult to bend the extruded rectangular tube-shaped protector, and it is difficult to restrict the wire even in a combined arrangement route of the straight portion and the curved portion. Regarding Request 3, since the application portion of the extruded rectangular tube-shaped protector is limited to the straight portion of the electric wire arrangement path, as a result, the component cost relative to the electric wire protection application portion is relatively high. It will be bigger.
　なお、要請４に関しても、押出成形された角筒状のプロテクタ自体は、剛体であるため、車両に容易に取付けることができるものの、電線の曲線部分は車両に対して所定の配設経路で支持することはできない。このため、電線の全体を車両に取付けるという観点からすると、不十分なものであるといえる。 Regarding request 4, the extruded rectangular tube protector itself is a rigid body and can be easily attached to the vehicle, but the curved portion of the electric wire is supported by a predetermined arrangement route with respect to the vehicle. I can't do it. For this reason, it can be said that it is insufficient from the viewpoint of attaching the entire electric wire to the vehicle.
　背景技術３では要請４を満たすことは満たすことは困難である。コルゲートチューブは形状自由度が高いため、電線を所定の配設経路に沿って経路規制しつつ車両に組込むためには、コルゲートチューブを多数箇所で車両に固定する必要があるからである。 In the background art 3, it is difficult to satisfy the requirement 4. This is because the corrugated tube has a high degree of freedom in shape, and it is necessary to fix the corrugated tube to the vehicle at many places in order to incorporate the electric wire into the vehicle while regulating the route along a predetermined arrangement route.
　背景技術４については、背景技術２と同様に、要請２及び３を満たすことは難しいし、また、電線の全体を車両に取付けるという観点からすると、要旨４に関しても、不十分なものであるといえる。 As for Background Art 4, as in Background Art 2, it is difficult to satisfy Requests 2 and 3, and from the viewpoint of attaching the entire wire to the vehicle, Summary 4 is also insufficient. I can say that.
　このように、背景技術１～４のいずれの場合でも、上記要請１～４を同時に満たすことは難しい。 Thus, in any of the background techniques 1 to 4, it is difficult to satisfy the above requests 1 to 4 at the same time.
　そこで、本発明は、電線をその周辺部材との干渉から保護でき、直線部分と曲線部分との複合的な配設経路でも、電線を経路規制でき、低製造コスト化でき、さらに、外装部材を車両に取付けるコストの低減を図ることを目的とする。 Therefore, the present invention can protect the electric wire from interference with its peripheral members, can regulate the electric wire even in a combined arrangement route of the straight portion and the curved portion, can reduce the manufacturing cost, The object is to reduce the cost of mounting on a vehicle.

The vehicle fixing component is cut and attached to the vehicle fixing component mounting portion in a state where the vehicle fixing component is locked to the remaining portion of the plurality of reinforcing protrusions.

　第８の態様は、第１～第７のいずれか１つの態様に係る電線外装部材であって、その延在方向の一部に電線固定用開口が形成され、電線固定部品が前記電線固定用開口を通じて内部の電線を内部に向けて押込可能に構成されているものである。 An eighth aspect is an electric wire exterior member according to any one of the first to seventh aspects, wherein an electric wire fixing opening is formed in a part of the extending direction, and the electric wire fixing component is the electric wire fixing member. It is comprised so that an internal electric wire can be pushed inward through opening.

　第１１の態様に係る電線モジュールは、第１～第１０のいずれか１つの態様に係る電線外装部材と、前記電線外装部材内に収容された電線と、を備える。 An electric wire module according to an eleventh aspect includes an electric wire exterior member according to any one of the first to tenth aspects and an electric wire accommodated in the electric wire exterior member.
　第１２の態様に係る電線外装部材の製造方法は、樹脂を押出成形することによって、電線を少なくとも３方から囲むことが可能な断面形状を呈すると共にその延在方向に沿って補強用突部が形成された長尺状のベース部材を形成する工程と、前記ベース部材に対して、その延在方向において部分的に曲げ容易にするための切離部を形成する工程とを備える。 In the method of manufacturing the electric wire exterior member according to the twelfth aspect, the extrusion protrusion of the resin exhibits a cross-sectional shape that can surround the electric wire from at least three directions, and the reinforcing protrusions extend along the extending direction. Forming a long base member formed, and forming a separating portion for making the base member partially bendable in the extending direction.
　第１～第１２の態様によると、電線を少なくとも３方から囲むため、電線とその周辺部材との干渉から保護できる。また、切離部が形成された部分で電線外装部材を曲げることができるため、直線部分と曲線部分との複合的な配設経路でも、電線を経路規制できる。また、本電線外装部材は、主として、樹脂を押出成形し、必要に応じて切離部を形成することで製造することができるため、製造コストを低減することができる。また、本電線外装部材は、切離部が形成されていない部分では、補強用突部によってある程度の剛性を保って直線性を維持することができ、また、切離部が形成された部分では比較的容易に曲げることができる。このため、電線を直線的な状態で保護する部分と電線を曲げた状態で保護する部分とを一体的に車両に取付けることができ、かつ、その取付箇所も少なくすることができる。これにより、本電線外装部材を車両に取付けるコストの低減を図ることも可能となる。 According to the first to twelfth aspects, since the electric wire is surrounded from at least three directions, it can be protected from interference between the electric wire and its peripheral members. Moreover, since the electric wire exterior member can be bent at the portion where the separation portion is formed, the electric wire can be restricted even in a combined arrangement route of the straight portion and the curved portion. Moreover, since this electric wire exterior member can be manufactured mainly by extruding resin and forming a separation part as needed, manufacturing cost can be reduced. In addition, the electric wire exterior member can maintain a certain degree of rigidity by a reinforcing protrusion in a portion where the separation portion is not formed, and can maintain linearity in a portion where the separation portion is formed. It can be bent relatively easily. For this reason, the part which protects an electric wire in a linear state, and the part which protects an electric wire in the bent state can be integrally attached to a vehicle, and the attachment location can also be reduced.

　以下、実施形態に係る電線外装部材、電線モジュール及び電線外装部材の製造方法について説明する。 Hereinafter, the manufacturing method of the electric wire exterior member, electric wire module, and electric wire exterior member which concern on embodiment is demonstrated.
　＜電線モジュール及び電線外装部材について＞
　図１は電線モジュール１０を示す概略斜視図であり、図２は電線外装部材２０をその延在方向に対して直交する面で切断した概略断面図であり、図３及び図４は電線外装部材２０の曲げ部分を示す説明図であり、図５は電線外装部材２０に車両固定用部品取付部４０を取付けた部分を示す概略斜視図であり、図６は同部分を示す概略断面図であり、図７は電線外装部材２０の分岐用の開口３６部分を示す概略斜視図である。 <About electric wire module and electric wire exterior member>
1 is a schematic perspective view showing the electric wire module 10, FIG. 2 is a schematic cross-sectional view of the electric wire exterior member 20 cut along a plane orthogonal to the extending direction, and FIGS. 3 and 4 are electric wire exterior members. FIG. 5 is a schematic perspective view showing a portion where a vehicle fixing part mounting portion 40 is attached to the electric wire exterior member 20, and FIG. 6 is a schematic cross-sectional view showing the same portion. FIG. 7 is a schematic perspective view showing a branch opening 36 portion of the electric wire exterior member 20.
　電線モジュール１０は、電線外装部材２０と、電線外装部材２０内に収容された電線１３とを備える。 The electric wire module 10 includes an electric wire exterior member 20 and an electric wire 13 accommodated in the electric wire exterior member 20.
　電線１３は、導線の周囲に押出被覆等によって被覆が施されたものである。導線は、銅、銅合金、アルミニウム、又はアルミニウム合金等によって形成される。被覆は、ポリ塩化ビニル（ＰＶＣ）、ポリプロピレン（ＰＰ）、ポリエチレン（ＰＥ）等をベース樹脂とし、これに難燃剤、柔軟剤等の添加剤を添加した絶縁樹脂によって形成されている。かかる電線１３自体は、比較的容易に曲り得るし、また、他の周辺部材と繰返し接触することによって摩耗等する。そこで、本電線モジュール１０では、電線１３を電線外装部材２０内に収容することによって、電線１３の経路をある程度規制して他の部材との接触を抑制すると共に、電線１３が他の周辺部材と接触可能な位置に配設されたとしても、電線１３と当該他の周辺部材との接触によって摩耗等しないように保護する。 The electric wire 13 is obtained by covering the conductive wire with extrusion coating or the like. The conducting wire is formed of copper, copper alloy, aluminum, aluminum alloy, or the like. The coating is formed of an insulating resin in which polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE) or the like is used as a base resin, and additives such as flame retardants and softeners are added thereto. The electric wire 13 itself can be bent relatively easily, and is worn by repeated contact with other peripheral members. Therefore, in the electric wire module 10, by accommodating the electric wire 13 in the electric wire exterior member 20, the path of the electric wire 13 is restricted to some extent to suppress contact with other members, and the electric wire 13 is connected to other peripheral members. Even if it is disposed at a position where it can be contacted, it is protected from being worn by contact between the electric wire 13 and the other peripheral members.
　ここでは、電線モジュール１０は、複数の電線１３を含む。複数の電線１３は、その延在方向の途中位置で分岐されつつ束ねられたワイヤーハーネス１２の形態で、電線外装部材２０に組込まれている。ワイヤーハーネス１２には、光ファイバコード等が含まれていてもよい。なお、各図では、電線１３は、束ねられたワイヤーハーネス１２の形態で図示されており、図１の一部においてのみ個別の電線１３が図示されている。 Here, the electric wire module 10 includes a plurality of electric wires 13. The plurality of electric wires 13 are incorporated in the electric wire exterior member 20 in the form of a wire harness 12 that is bundled while being branched at a midway position in the extending direction. The wire harness 12 may include an optical fiber cord or the like. In addition, in each figure, the electric wire 13 is illustrated in the form of the bundled wire harness 12, and the individual electric wires 13 are illustrated only in a part of FIG.
　上記各電線１３の端部には、端子が接続されている。複数の端子は、コネクタに組込まれる。そして、本電線モジュール１０が車両等に取付けられた状態で、コネクタが車両に搭載された電気制御ユニット、各種センサ、各種駆動機器に接続される。これにより、本電線モジュール１０は、車両に搭載された各種電気部品同士を電気的に接続する配線材として用いられる。 A terminal is connected to the end of each electric wire 13. The plurality of terminals are incorporated in the connector. And in the state which this electric wire module 10 was attached to the vehicle etc., a connector is connected to the electric control unit mounted in the vehicle, various sensors, and various drive devices. Thereby, this electric wire module 10 is used as a wiring material which electrically connects the various electric components mounted in the vehicle.
　電線外装部材２０は、軟化した樹脂を押出成形することによって形成された長尺部材である。ここで、押出成形とは、軟化した樹脂を押出成形用金型に供給して、所定の断面形状を持つ長尺部材として押出す加工方法である。長尺部材は、押出成形用金型の出口の形状に応じた所定断面形状の部材として製造される。このため、押出成形用金型の出口形状を、電線外装部材２０として加工したい所定形状に形成しておくことで、延在方向に沿って同一断面形状を呈する長尺部材を連続的に容易に成形することができる。 The electric wire exterior member 20 is a long member formed by extruding a softened resin. Here, the extrusion molding is a processing method in which a softened resin is supplied to an extrusion molding die and extruded as a long member having a predetermined cross-sectional shape. The long member is manufactured as a member having a predetermined cross-sectional shape corresponding to the shape of the outlet of the extrusion mold. For this reason, by forming the outlet shape of the extrusion molding die into a predetermined shape to be processed as the electric wire exterior member 20, it is possible to easily and continuously form a long member having the same cross-sectional shape along the extending direction. Can be molded.
　電線外装部材２０の横断面形状（電線外装部材２０の延在方向において直交する面における断面形状）は、電線１３を少なくとも３方から囲むことが可能な断面形状を呈しており、ここでは、電線１３の周囲全体を囲む閉断面形状を呈している。 The cross-sectional shape of the wire sheathing member 20 (cross-sectional shape in the plane orthogonal to the extending direction of the wire sheathing member 20) is a cross-sectional shape that can surround the wire 13 from at least three directions. 13 has a closed cross-sectional shape surrounding the entire periphery.
　具体的には、電線外装部材２０は、多角形筒形状の一例として、四角筒形状をなす本体部２２を備える。ここでは、本体部２２の横断面形状は、一組の対辺（図２では横方向に沿った対辺）が他の組の対辺（図３では縦方向に沿った対辺）よりも長い長方形状の横断面形状（多角形断面形状の一例）を呈する。より具体的には、本体部２２は、底板部２３と、上板部２４と、一対の側板部２５、２５とで囲まれる角筒形状をなしている。以下では、底板部２３と上板部２４とを結ぶ方向を上下方向、一対の側板部２５、２５を結ぶ方向を幅方向として説明するが、車両における電線外装部材２０の配設態様がそれらの方向に限定されるものではない。 Specifically, the electric wire exterior member 20 includes a main body 22 having a quadrangular cylindrical shape as an example of a polygonal cylindrical shape. Here, the cross-sectional shape of the main body 22 is a rectangular shape in which one set of opposite sides (the opposite sides along the horizontal direction in FIG. 2) is longer than the other set of opposite sides (the opposite sides along the vertical direction in FIG. 3). Presents a cross-sectional shape (an example of a polygonal cross-sectional shape). More specifically, the main body portion 22 has a rectangular tube shape surrounded by a bottom plate portion 23, an upper plate portion 24, and a pair of side plate portions 25 and 25. Hereinafter, the direction connecting the bottom plate portion 23 and the upper plate portion 24 will be described as the vertical direction, and the direction connecting the pair of side plate portions 25, 25 will be described as the width direction. It is not limited to the direction.
　なお、電線外装部材は、上記したように、外周囲の一部が開口する半筒形状等であってもよい。もっとも、電線外装部材２０が上記のように電線１３の周囲全体を囲む閉断面形状を呈していれば、電線１３をより確実に保護することができる。 In addition, as above-mentioned, the semi-cylindrical shape etc. which a part of outer periphery opens may be sufficient as an electric wire exterior member. But if the electric wire exterior member 20 is exhibiting the closed cross-sectional shape surrounding the whole circumference | surroundings of the electric wire 13 as mentioned above, the electric wire 13 can be protected more reliably.
　また、電線外装部材は、円筒、楕円筒形状、三角筒形状等であってもよい。もっとも、電線外装部材２０が多角形筒形状（例えば、四角筒形状）であれば、捻れ難くなるというメリットがある。 Further, the electric wire exterior member may have a cylindrical shape, an elliptical cylindrical shape, a triangular cylindrical shape, or the like. But if the electric wire exterior member 20 is a polygonal cylinder shape (for example, square cylinder shape), there exists a merit that it becomes difficult to twist.
　また、電線外装部材２０には、その延在方向に沿って電線１３を収容するためのスリット２１が形成されている。スリット２１は、電線外装部材２０の押出成形時に形成されていてもよいし、押出成形後、カッター刃、レーザー切断等で切断されて形成されていてもよい。前者の場合、スリット２１は、押出成形後に閉じてしまわないように僅かな幅を有するスリット２１に形成されるが、かかるスリット２１が形成されている場合も、電線１３の断面形状が、電線１３の周囲を囲む閉断面形状を呈する場合に含まれる。 In addition, the electric wire exterior member 20 is formed with a slit 21 for accommodating the electric wire 13 along its extending direction. The slit 21 may be formed at the time of extrusion molding of the electric wire exterior member 20, or may be formed by being cut by a cutter blade, laser cutting or the like after the extrusion molding. In the former case, the slit 21 is formed in a slit 21 having a slight width so as not to be closed after extrusion, but even when the slit 21 is formed, the cross-sectional shape of the electric wire 13 is the electric wire 13. It is included when exhibiting a closed cross-sectional shape surrounding the periphery of the.
　また、電線外装部材２０の本体部２２には、その延在方向に沿って延びる補強用突部２６、２７が形成されている。 Further, the main body portion 22 of the electric wire exterior member 20 is formed with reinforcing protrusions 26 and 27 extending along the extending direction.
　ここでは、底板部２３の両側縁部より一対の側板部２５の外方に向けて細長板状の補強用突部２６が一対形成されている。また、一対の側板部２５のうち上板部２４側の縁部より上板部２４の外方（上方）に向けて細長板状の補強用突部２７が一対形成されている。ここでは、各補強用突部２６、２７は、その外側に向けて徐々に薄くなる形状に形成されているが、これは必須ではない。このように、補強用突部２６と補強用突部２７とで突出方向を異ならせることで、電線外装部材２０をその幅方向及び上下方向に曲りに難くすることができ、直線状態をより確実に維持することが可能となる。 Here, a pair of elongate plate-shaped reinforcing protrusions 26 are formed from both side edge portions of the bottom plate portion 23 toward the outside of the pair of side plate portions 25. Further, a pair of elongated projections 27 for reinforcing are formed from the edge on the upper plate portion 24 side of the pair of side plate portions 25 toward the outside (upward) of the upper plate portion 24. Here, each of the reinforcing protrusions 26 and 27 is formed in a shape that gradually becomes thinner toward the outside thereof, but this is not essential. Thus, by making the protruding directions different between the reinforcing protrusions 26 and the reinforcing protrusions 27, the electric wire exterior member 20 can be made difficult to bend in the width direction and the vertical direction, and the straight line state can be more reliably ensured. Can be maintained.
　なお、上記補強用突部２６、２７は、電線外装部材２０の横断面形状において、側方及び上方に突出する突起形状として表れる。上記本体部２２及び補強用突部２６、２７とを含む構成部分が、樹脂の押出成形によって形成されている。 The reinforcing protrusions 26 and 27 appear as protrusions protruding sideways and upward in the cross-sectional shape of the electric wire exterior member 20. The components including the main body 22 and the reinforcing protrusions 26 and 27 are formed by resin extrusion.
　また、電線外装部材２０には、その延在方向に部分的に曲げ容易にするための切離部３０、３１が形成されている。切離部３０、３１は、電線外装部材２０の外周部の一部を、その延在方向両側で切離した部分であり、上記押出成形された長尺部材に対して追加加工することで形成される。切離部３０、３１の追加加工は、プレス刃、カッター刃、レーザー切断等によって形成することができる。切離部３０、３１は、電線外装部材２０の外周部の一部に形成されていればよく、従って、補強用突部２６（又は２７）だけに形成されていてもよいし、本体部２２の外周部の一部に内外貫くように形成されていてもよい。 Moreover, the wire exterior member 20 is formed with separation portions 30 and 31 for making it easy to bend partially in the extending direction. The separation parts 30 and 31 are parts where a part of the outer peripheral part of the electric wire exterior member 20 is separated on both sides in the extending direction, and are formed by performing additional processing on the extruded long member. The The additional processing of the separation parts 30 and 31 can be formed by a press blade, a cutter blade, laser cutting, or the like. The cut-off portions 30 and 31 may be formed on a part of the outer peripheral portion of the electric wire exterior member 20, and thus may be formed only on the reinforcing projection 26 (or 27), or the main body portion 22. It may be formed so as to penetrate inside and outside of a part of the outer peripheral portion.
　ここでは、電線外装部材２０の延在方向中間部における第１部分２８が、２箇所の部分２８ａ、２８ｂで互いに逆方向に緩やかに曲げられ、平面視において緩やかなＳ字状カーブを描くように曲げられる（図１及び図３参照）。 Here, the first portion 28 in the intermediate portion in the extending direction of the wire sheathing member 20 is gently bent in opposite directions at the two portions 28a and 28b so as to draw a gentle S-shaped curve in plan view. It is bent (see FIGS. 1 and 3).
　このため、第１部分２８の部分２８ａのうち曲げられた状態で外周側を向く部分に、間隔をあけて複数の切離部３０が形成されている。ここでは、電線外装部材２０のうち一方側の補強用突部２６に切離部３０が形成されている。このため、第１部分２８の部分２８ａを、一方側の補強用突部２６を各切離部３０で開くようにして、容易に曲げることができる。 For this reason, a plurality of separation portions 30 are formed at intervals in a portion of the portion 28a of the first portion 28 that faces the outer peripheral side in a bent state. Here, the separating portion 30 is formed in the reinforcing protrusion 26 on one side of the electric wire exterior member 20. For this reason, the portion 28a of the first portion 28 can be easily bent by opening the reinforcing protrusions 26 on one side at the respective separation portions 30.
　同様に、第１部分２８の部分２８ｂのうち曲げられた状態で外周側を向く部分に、間隔をあけて複数の切離部３０が形成されている。ここでは、電線外装部材２０のうち他方側の補強用突部２６に切離部３０が形成されている。このため、第１部分２８の部分２８ｂを、他方側の補強用突部２６を各切離部３０で開くようにして、容易に曲げることができる。 Similarly, a plurality of separation portions 30 are formed at intervals in the portion 28b of the first portion 28 that faces the outer peripheral side in a bent state. Here, the separating portion 30 is formed in the reinforcing protrusion 26 on the other side of the electric wire exterior member 20. For this reason, the portion 28b of the first portion 28 can be easily bent by opening the other-side reinforcing projection 26 at each separation portion 30.
　また、電線外装部材２０の延在方向中間部における第２部分２９が上下方向に緩やかに曲げられている（図１及び図４参照）。 Further, the second portion 29 at the intermediate portion in the extending direction of the electric wire exterior member 20 is gently bent in the vertical direction (see FIGS. 1 and 4).
　第２部分２９のうち曲げられた状態で外周側を向く部分に、間隔をあけて複数の切離部３１が形成されている。ここでは、電線外装部材２０のうち両方の補強用突部２７に切離部３１が形成されている。このため、第２部分２９を、両補強用突部２７を各切離部３１で開くようにして、容易に曲げることができる。 A plurality of separation portions 31 are formed at intervals in a portion of the second portion 29 that faces the outer peripheral side in a bent state. Here, the separation part 31 is formed in both the reinforcement protrusions 27 of the electric wire exterior member 20. For this reason, the second portion 29 can be easily bent by opening both the reinforcing projections 27 at the respective separation portions 31.
　これにより、第２部分２９を、容易に曲げることができる。勿論、曲げ方向、曲げの程度によっては、切離部は、本体部２２を貫くように形成されていてもよい。もっとも、補強用突部２６（又は２７）だけを切離す構成とすることで、内部の電線１３をより確実に保護することが可能となる。 Thereby, the second portion 29 can be easily bent. Of course, depending on the bending direction and the degree of bending, the separating portion may be formed so as to penetrate the main body portion 22. But it becomes possible to protect the internal electric wire 13 more reliably by setting it as the structure which isolate | separates only the protrusion 26 (or 27) for reinforcement.
　また、本実施形態では、切離部は、線状に切離す形状に形成されているが、切離部は、電線外装部材をその延在方向において幅をあけて切離す形状に形成されていてもよい。 Further, in the present embodiment, the separation portion is formed in a shape that separates linearly, but the separation portion is formed in a shape that separates the electric wire exterior member with a width in the extending direction. May be.
　勿論、本電線外装部材２０はその形成材料によっては、切離部を形成しなくても、ある程度は曲ることができるため、緩やかな曲げ形状等である場合には、上記切離部を形成せずに、曲げるようにしてもよい。 Of course, the wire outer packaging member 20 can be bent to some extent without forming a separation portion depending on the forming material. Therefore, in the case of a gentle bending shape, the separation portion is formed. You may make it bend without doing.
　この電線外装部材２０は、柔軟性を有する材料によって形成されていることが好ましく、具体的には、内部に収容される電線１３と同程度の柔軟性を有する材料によって形成されていることが好ましい。これにより、電線１３と電線外装部材２０との接触による異音を抑制することができる。また、本電線外装部材２０を容易に曲げることも可能となる。 The electric wire exterior member 20 is preferably formed of a material having flexibility, and specifically, is preferably formed of a material having the same degree of flexibility as the electric wire 13 accommodated therein. . Thereby, the noise by the contact with the electric wire 13 and the electric wire exterior member 20 can be suppressed. In addition, the electric wire exterior member 20 can be easily bent.
　さらには、電線外装部材２０は、内部に収容される電線１３の被覆のベース樹脂と同じベース樹脂の材料によって形成されていることが好ましい。すなわち、電線１３の被覆がポリ塩化ビニル（ＰＶＣ）、ポリプロピレン（ＰＰ）、ポリエチレン（ＰＥ）等をベース樹脂とする材料によって形成されている場合には、電線外装部材２０もこれらと同じベース樹脂の合成樹脂によって形成されていることが好ましい。これにより、電線外装部材２０と電線１３を構成する樹脂の少なくとも一部を共通化して、本電線外装部材２０を低コストで製造することが可能となる。なお、この場合、添加剤については、電線１３の被覆を構成する合成樹脂と、電線外装部材２０を構成する合成樹脂とで、同じである必要はない。もっとも、電線外装部材２０が、内部に収容される電線１３の被覆のベース樹脂と同じベース樹脂の材料によって形成されていることは必須ではない。 Furthermore, it is preferable that the electric wire exterior member 20 is formed of the same base resin material as the base resin for covering the electric wires 13 accommodated therein. That is, when the covering of the electric wire 13 is made of a material having a base resin such as polyvinyl chloride (PVC), polypropylene (PP), or polyethylene (PE), the electric wire exterior member 20 is also made of the same base resin. It is preferably formed of a synthetic resin. As a result, at least a part of the resin constituting the wire sheathing member 20 and the wire 13 can be shared, and the wire sheathing member 20 can be manufactured at low cost. In this case, the additive does not need to be the same for the synthetic resin constituting the covering of the electric wire 13 and the synthetic resin constituting the electric wire exterior member 20. But it is not essential that the electric wire exterior member 20 is formed with the same base resin material as the base resin of the coating | cover of the electric wire 13 accommodated in an inside.
　また、この電線外装部材２０には、車両固定用部品取付部３２が形成されている。ここでは、補強用突部２６がその延在方向において部分的に切除されて凹部３２ａが形成されることによって、電線外装部材２０のうち凹部３２ａが形成された部分に、車両固定用部品４０を取付可能な車両固定用部品取付部３２が形成されている（図１、図５及び図６参照）。なお、凹部３２ａは、補強用突部２７の延在方向において、後述する側板部４４の幅と同程度の幅に設定されている。 Further, the electric wire exterior member 20 is formed with a vehicle fixing component mounting portion 32. Here, the reinforcing protrusion 26 is partially cut off in the extending direction to form the recess 32a, so that the vehicle fixing component 40 is placed on the portion of the electric wire exterior member 20 where the recess 32a is formed. A vehicle fixing component mounting portion 32 that can be mounted is formed (see FIGS. 1, 5 and 6). In addition, the recessed part 32a is set to the width | variety comparable as the width | variety of the side plate part 44 mentioned later in the extension direction of the protrusion 27 for reinforcement.
　なお、ここで、車両固定用部品取付部３２では、複数の補強用突部２６、２７のうちの一部である補強用突部２６がその延在方向において部分的に切除され、残りの補強用突部２７は切除されていない。そして、車両固定用部品４０は、前記凹部３２ａに嵌り込むと共に、補強用突部２７に係止した状態で、車両固定用部品取付部３２に取付けられている。 Here, in the vehicle fixing component mounting portion 32, the reinforcing protrusion 26, which is a part of the plurality of reinforcing protrusions 26, 27, is partially cut away in the extending direction, and the remaining reinforcement is provided. The projecting protrusion 27 is not excised. The vehicle fixing component 40 is attached to the vehicle fixing component mounting portion 32 in a state where the vehicle fixing component 40 is fitted in the concave portion 32 a and is locked to the reinforcing protrusion 27.
　ここで、車両固定用部品４０は、樹脂等によって金型一体成型された部品であり、電線外装部材２０に取付可能な外装部材取付部４２と、車両に固定可能な車両固定部４６とを備える。 Here, the vehicle fixing part 40 is a part integrally molded with resin or the like, and includes an exterior member attaching part 42 that can be attached to the electric wire exterior member 20 and a vehicle fixing part 46 that can be fixed to the vehicle. .
　外装部材取付部４２は、底板部２３の外面にその幅方向全体に亘って配設可能な板状部４３と、板状部４３の両側部から板状部４３の一方主面側に立上がる一対の側板部４４とを備える。一対の側板部４４は、上下方向において、側板部２５及び補強用突部２７の高さ寸法と同程度の長さ寸法に設定されている。また、一対の側板部４４のそれぞれの先端部から内側に戻るようにして係止片４５が形成されている。側板部４４の先端部内向き面と係止片４５の外向き面との間に、側板部２５の基端側に向けて開口して、補強用突部２７を配設可能な空間が形成されている。 The exterior member attaching portion 42 rises from the both sides of the plate-like portion 43 to one main surface side of the plate-like portion 43 on the outer surface of the bottom plate portion 23 over the entire width direction. A pair of side plate portions 44. The pair of side plate portions 44 is set to have a length dimension approximately the same as the height dimension of the side plate portion 25 and the reinforcing projection 27 in the vertical direction. Further, a locking piece 45 is formed so as to return inward from the respective front end portions of the pair of side plate portions 44. A space is formed between the inward surface of the front end of the side plate portion 44 and the outward surface of the locking piece 45 so as to open toward the base end side of the side plate portion 25 so that the reinforcing protrusion 27 can be disposed. ing.
　そして、板状部４３の上面を底板部２３の下面に接触させると共に、一対の側板部４４の内向き面を一対の側板部２５の外面に接触させ、さらに、一対の側板部４４の先端部内向き面と一対の係止片４５の外向き面との間のそれぞれに一対の補強用突部２７を配設して、車両固定用部品４０を補強用突部２７に係合させることで、車両固定用部品４０が車両固定用部品取付部３２に取付けられる。 And while making the upper surface of the plate-shaped part 43 contact the lower surface of the baseplate part 23, the inward surface of a pair of side plate part 44 is made to contact the outer surface of a pair of side plate part 25, and also in the front-end | tip part of a pair of side plate part 44 By arranging a pair of reinforcing projections 27 between the facing surfaces and the outward surfaces of the pair of locking pieces 45, the vehicle fixing component 40 is engaged with the reinforcing projections 27. The vehicle fixing component 40 is attached to the vehicle fixing component mounting portion 32.
　この状態では、車両固定用部品４０の一対の側板部４４の基端部は、凹部３２ａ間に収容されるため、当該車両固定用部品４０は、電線外装部材２０に対してその延在方向一定位置に取付けられる。 In this state, since the base end portions of the pair of side plate portions 44 of the vehicle fixing component 40 are accommodated between the recesses 32a, the vehicle fixing component 40 has a constant extension direction with respect to the electric wire exterior member 20. Mounted in position.
　また、電線外装部材２０の本体部２２が多角形断面形状を呈しており、板状部４３及び一対の側板部４４のそれぞれが底板部２３及び一対の側板部２５に接していること、及び、側板部４４の先端部と係止片４５とが補強用突部２７に係止していること、の少なくとも一方の構成によって、車両固定用部品４０は、電線外装部材２０に対してその周方向一定位置に取付けられ，その周方向への回転が抑制されている。 Further, the main body portion 22 of the electric wire exterior member 20 has a polygonal cross-sectional shape, and the plate-like portion 43 and the pair of side plate portions 44 are in contact with the bottom plate portion 23 and the pair of side plate portions 25, and Due to at least one of the configuration in which the distal end portion of the side plate portion 44 and the locking piece 45 are locked to the reinforcing protrusion 27, the vehicle fixing component 40 is circumferential with respect to the electric wire exterior member 20. It is mounted at a fixed position and its rotation in the circumferential direction is suppressed.
　車両固定部４６は、車両に固定可能に構成されている。ここでは、車両固定部４６は、板状部４３の中央部から外方に向けて突出する柱状部４６ａと、柱状部４６ａの先端部に突設された抜止め突部４６ｂとを備える。そして、車両に形成された取付孔に本車両固定部４６を挿入すると、前記抜止め突部４６ｂが取付孔の周縁部に抜止め係止し、もって、車両固定部４６が車両に対して一定位置に固定される。 The vehicle fixing portion 46 is configured to be fixed to the vehicle. Here, the vehicle fixing portion 46 includes a columnar portion 46a that protrudes outward from the central portion of the plate-like portion 43, and a retaining protrusion 46b that protrudes from the tip of the columnar portion 46a. When the vehicle fixing portion 46 is inserted into the mounting hole formed in the vehicle, the retaining protrusion 46b is retained and locked to the peripheral edge of the mounting hole, so that the vehicle fixing portion 46 is fixed to the vehicle. Fixed in position.
　車両に固定可能な車両固定部に係る構成は、上記例に限られない。例えば、車両固定部は、車両に形成された帯状部分の両側部に係止することによって、車両に固定される構成であってもよい。また、車両固定部は、車両に設けられたスタッドボルト、板状のブラケット板等に固定される構成であってもよい。 The configuration related to the vehicle fixing portion that can be fixed to the vehicle is not limited to the above example. For example, the vehicle fixing portion may be configured to be fixed to the vehicle by being engaged with both side portions of a belt-like portion formed on the vehicle. Further, the vehicle fixing portion may be configured to be fixed to a stud bolt, a plate-like bracket plate or the like provided in the vehicle.
　また、電線外装部材２０の延在方向の中間部には、その内部に収容された電線１３を外部に導き出すための開口３６が形成されている（図１及び図７参照）。ここでは、底板部２３の一側よりの部分と一方の側板部２５の側板部４４よりの部分とが、連続する１つの開口３６を形成するように切除されている。開口３６は、打抜き刃、カッター刃、レーザー切断等によって形成することができる。 Further, an opening 36 for leading the electric wire 13 accommodated in the inside of the extending portion of the electric wire exterior member 20 to the outside is formed (see FIGS. 1 and 7). Here, a portion from one side of the bottom plate portion 23 and a portion from the side plate portion 44 of one side plate portion 25 are cut out so as to form one continuous opening 36. The opening 36 can be formed by a punching blade, a cutter blade, laser cutting, or the like.
　上記開口３６を通じて、電線外装部材２０内の電線１３が外部に導き出される。通常は、ワイヤーハーネス１２が電線外装部材２０内で分岐しており、その分岐部分１２ａが当該開口３６を通じて外部に導き出される。 The electric wire 13 in the electric wire exterior member 20 is led out through the opening 36. Usually, the wire harness 12 is branched in the electric wire exterior member 20, and the branched portion 12 a is led to the outside through the opening 36.
　＜製造方法について＞
　上記電線外装部材２０の製造方法例について、図８を参照して説明する。 <About manufacturing method>
An example of a method for manufacturing the electric wire exterior member 20 will be described with reference to FIG.
　まず、電線外装部材２０の断面形状に応じた樹脂の出口を有する押出成形装置９０によって、軟化した樹脂を押出成形することによって、電線を少なくとも３方から囲むことが可能な断面形状を呈すると共にその延在方向に沿って補強用突部が形成された長尺状のベース部材２０Ｂを形成する。ベース部材２０Ｂは、複数個の電線外装部材２０を形成可能な長尺部材として連続的に形成される。このように、複数の電線外装部材２０分のベース部材２０Ｂを連続して形成することで、低コストかつ短時間で多数の電線外装部材２０を製造できる。また、押出成形用の金型は比較的簡易な形状であるため、射出成形用の金型と比較して安価な装置となる。 First, by extruding the softened resin with an extrusion molding apparatus 90 having a resin outlet corresponding to the cross-sectional shape of the electric wire exterior member 20, the cross-sectional shape that can surround the electric wire from at least three directions is exhibited. A long base member 20B having reinforcing protrusions formed along the extending direction is formed. The base member 20 </ b> B is continuously formed as a long member capable of forming a plurality of electric wire exterior members 20. As described above, by continuously forming the base members 20B for the plurality of electric wire exterior members 20, a large number of the electric wire exterior members 20 can be manufactured in a low cost and in a short time. In addition, since the mold for extrusion molding has a relatively simple shape, it is an inexpensive apparatus compared with the mold for injection molding.
　この後、ベース部材２０Ｂに対して、その延在方向において部分的に曲げ容易にするための切離部３０を形成する。図８に示す例では、プレス刃によって切離部３０を形成するプレス加工装置９４によって切離部３０を形成する状態を示している。なお、連続的に搬送されるベース部材２０Ｂは、プレス加工装置９４に送られる段階では、一対の送りローラ９６を有する搬送装置によって断続的に搬送し、停止した状態で上記切離部３０を形成する処理を行うとよい。なお、必要に応じて、上記開口３６、凹部３２ａを形成してもよい。 Thereafter, a separation portion 30 is formed on the base member 20B to facilitate partial bending in the extending direction. In the example shown in FIG. 8, the state which forms the separation part 30 with the press processing apparatus 94 which forms the separation part 30 with a press blade is shown. The base member 20 </ b> B that is continuously conveyed is intermittently conveyed by a conveying device having a pair of feeding rollers 96 in the stage where the base member 20 </ b> B is sent to the press working device 94, and the separation part 30 is formed in a stopped state. It is good to perform the process to do. In addition, you may form the said opening 36 and the recessed part 32a as needed.
　なお、ベース部材２０Ｂに対する加工装置は、ベース部材２０Ｂの各板状部分等を加工する装置であるため、比較的軽い力で加工が可能である。このため、当該加工装置自体も比較的安価な設備とすることができる。 In addition, since the processing apparatus with respect to the base member 20B is an apparatus which processes each plate-shaped part etc. of the base member 20B, it can process with comparatively light force. For this reason, the said processing apparatus itself can also be set as a comparatively cheap installation.
　この後、切断刃９８によって、ベース部材２０Ｂを切断すると、ワイヤーハーネス１２の保護対象部分の長さに応じた電線外装部材２０が製造される。 Thereafter, when the base member 20B is cut by the cutting blade 98, the electric wire exterior member 20 corresponding to the length of the protection target portion of the wire harness 12 is manufactured.
　もっとも、上記ベース部材２０Ｂを切断した後に、切離部３０等を形成してもよい。もっとも、押出されたベース部材２０Ｂに対して連動するプレス加工装置９４等の加工装置によって追加加工を施すことによって、電線外装部材２０をより低コストで製造できる。 However, after the base member 20B is cut, the separating portion 30 and the like may be formed. But the electric wire exterior member 20 can be manufactured at a lower cost by performing additional processing with processing apparatuses, such as the press processing apparatus 94 which interlock | cooperates with respect to the extruded base member 20B.
　上記電線１３を含むワイヤーハーネス１２は、スリット２１を通じて電線外装部材２０内に収容される。この際、必要に応じて、ワイヤーハーネス１２の分岐部分１２ａが開口３６に通され外部に引出される。そして、必要に応じて、電線外装部材２０の端部、延在方向中間部等に粘着テープが巻回される。電線外装部材２０の端部に巻回された粘着テープ及び開口３６に巻回された粘着テープ等によって、電線外装部材２０とワイヤーハーネス１２とを固定するようにしてもよい。 The wire harness 12 including the electric wire 13 is accommodated in the electric wire exterior member 20 through the slit 21. At this time, if necessary, the branch portion 12a of the wire harness 12 is passed through the opening 36 and pulled out. And an adhesive tape is wound around the edge part of the electric wire exterior member 20, an extending direction intermediate part, etc. as needed. You may make it fix the electric wire exterior member 20 and the wire harness 12 with the adhesive tape wound around the edge part of the electric wire exterior member 20, the adhesive tape wound around the opening 36, etc. FIG.
　＜効果等＞
　以上のように構成された電線外装部材２０、電線モジュール１０及び電線外装部材２０の製造方法によると、電線外装部材２０は、電線１３を少なくとも３方向から囲むため、電線１３をその周辺部材との干渉から保護できる。また、電線外装部材２０のうち切離部３０が形成された部分を容易に曲げることができ、また、切離部３０が形成されていない部分では直線状態を維持することができる。このため、直線部分と曲線部分との複合的な配設経路でも、電線１３を経路規制できる。 <Effects>
According to the manufacturing method of the wire sheathing member 20, the wire module 10, and the wire sheathing member 20 configured as described above, the wire sheathing member 20 surrounds the wire 13 from at least three directions. Can protect against interference. Moreover, the part in which the separation part 30 was formed among the electric wire exterior members 20 can be bent easily, and the linear state can be maintained in the part in which the separation part 30 is not formed. For this reason, the electric wire 13 can be route-regulated even in a complex arrangement route of the straight portion and the curved portion.
　また、電線１３を直線的な状態で保護する部分（切離部３０が形成されていない部分）と電線１３を曲げた状態で保護する部分（切離部３０が形成された部分）とを一体的に車両に取付けることができ、かつ、その取付箇所も少なくすることができる。これにより、本電線外装部材２０を車両に取付けるコストの低減を図ることも可能となる。 In addition, a portion that protects the electric wire 13 in a linear state (portion where the separation portion 30 is not formed) and a portion that protects the electric wire 13 in a bent state (portion where the separation portion 30 is formed) are integrated. Therefore, it can be attached to a vehicle and the number of attachment points can be reduced. Thereby, it becomes possible to reduce the cost of attaching the electric wire exterior member 20 to the vehicle.
　また、電線外装部材２０は、主として、軟化した樹脂を押出成形し、必要に応じて切離部３０を形成することで製造することができるため、製造コストを低減することができる。 Moreover, since the electric wire exterior member 20 can be manufactured mainly by extruding a softened resin and forming the separation part 30 as necessary, the manufacturing cost can be reduced.
　また、補強用突部２６、２７によって電線外装部材２０の部分を直線状に維持することができるため、本体部２２の厚みを小さくすることができ、樹脂の使用量を削減できるというメリットもある。 Moreover, since the part of the electric wire exterior member 20 can be maintained in a straight line shape by the reinforcing protrusions 26 and 27, there is an advantage that the thickness of the main body portion 22 can be reduced and the amount of resin used can be reduced. .
　また、特に、電線外装部材２０が電線１３の周囲全体を囲む断面形状を呈することで、電線１３を十分に保護することができる。 In particular, since the electric wire exterior member 20 has a cross-sectional shape that surrounds the entire periphery of the electric wire 13, the electric wire 13 can be sufficiently protected.
　さらに、電線外装部材２０が多角形断面形状を呈することで、電線外装部材２０が捻れ難くなる。これにより、電線外装部材２０の取付方向、即ち、車両固定用部品４０の取付姿勢及び車両固定部４６の取付方向等に合わせて、電線外装部材２０の周方向の所定部分に切離部３０を形成することができ、設計上の所定方向に曲げるための加工が容易となる。 Furthermore, since the electric wire exterior member 20 exhibits a polygonal cross-sectional shape, the electric wire exterior member 20 becomes difficult to twist. Accordingly, the separation portion 30 is provided at a predetermined portion in the circumferential direction of the wire sheathing member 20 according to the mounting direction of the wire sheathing member 20, that is, the mounting orientation of the vehicle fixing component 40 and the mounting direction of the vehicle fixing portion 46. It can be formed, and processing for bending in a predetermined direction in design is facilitated.
　また、電線外装部材２０が捻れ難いため、車両固定用部品４０の取付位置が電線外装部材２０周りで正確な位置に維持される。このため、本電線外装部材２０の車両固定用部品４０を車両に対して容易に固定できる。 Moreover, since the electric wire exterior member 20 is difficult to twist, the mounting position of the vehicle fixing component 40 is maintained at an accurate position around the electric wire exterior member 20. For this reason, the vehicle fixing component 40 of the electric wire exterior member 20 can be easily fixed to the vehicle.
　これらの点に関しては、コルゲートチューブを用いた背景技術３及び硬質チューブを用いる背景技術４においては、円形断面を呈するコルゲートチューブ或は硬質チューブが捻れ易いため、取付方向と曲げ方向、分岐方向等をその周方向において一定取付方向と曲げ方向、分岐方向等をその周方向において一定位置に作り込み難い。また、コルゲートチューブ或は硬質チューブに車両固定部品を取付けても、コルゲートチューブがねじれてしまうので、車両固定用部品が車両への取付けに適した位置からずれてしまうことがあり、車両への固定作業が困難になる恐れがある。これに対して、本電線外装部材２０では、捻れ難いため、取付方向と曲げ方向、分岐方向等をその周方向において正確な位置に作り込み易く、また、作り込み後においても、所定位置に維持されるため、背景技術３及び４に対して有利である。 Regarding these points, in the background technology 3 using the corrugated tube and the background technology 4 using the hard tube, the corrugated tube or the hard tube having a circular cross section is easily twisted. In the circumferential direction, it is difficult to make a fixed mounting direction, a bending direction, a branching direction, and the like at a fixed position in the circumferential direction. Even if a vehicle fixing part is attached to a corrugated tube or a hard tube, the corrugated tube will be twisted, so that the parts for fixing the vehicle may deviate from the position suitable for attachment to the vehicle. Work may be difficult. On the other hand, since the electric wire exterior member 20 is not easily twisted, the mounting direction, the bending direction, the branching direction, and the like can be easily formed at accurate positions in the circumferential direction, and also maintained at a predetermined position even after the forming. Therefore, it is advantageous to the background arts 3 and 4.
　また、電線外装部材２０の断面形状、補強用突部２６、２７等を手がかりとして、電線外装部材２０の上下、左右等を比較的容易に判別することができる。このため、本電線外装部材２０を容易に車両に取付けることもできる。 Further, the upper and lower sides, the left and right sides, etc. of the electric wire exterior member 20 can be distinguished relatively easily by using the sectional shape of the electric wire exterior member 20 and the reinforcing protrusions 26 and 27 as clues. For this reason, this electric wire exterior member 20 can also be easily attached to a vehicle.
　また、電線外装部材２０に開口３６が形成されているため、その内部に収容された電線１３をその延在方向の中間部で他の電線１３から分岐等させて外部に導き出すことができ、各種配設経路のワイヤーハーネス１２に容易に対応することができる。 Moreover, since the opening 36 is formed in the electric wire exterior member 20, the electric wire 13 accommodated in the inside can be branched from the other electric wires 13 at the intermediate portion in the extending direction and led to the outside. It is possible to easily correspond to the wire harness 12 in the arrangement path.
　また、補強用突部２６がその延在方向中間部において部分的に切除されることにより凹部３２ａが形成され、電線外装部材２０のうち凹部３２ａが形成された部分によって車両固定用部品４０を取付可能な車両固定用部品取付部３２が形成されているため、車両固定用部品４０を電線外装部材２０の延在方向において一定位置に取付けできる。 Further, the reinforcing protrusion 26 is partially cut off at the intermediate portion in the extending direction to form a recess 32a, and the vehicle fixing component 40 is attached by the portion of the electric wire exterior member 20 where the recess 32a is formed. Since the possible vehicle fixing component mounting portion 32 is formed, the vehicle fixing component 40 can be mounted at a fixed position in the extending direction of the electric wire exterior member 20.
　また、補強用突部２６、２７が複数形成されており、車両固定用部品４０が補強用突部２７に係止した状態で、車両固定用部品取付部３２に取付けられるため、車両固定用部品４０が電線外装部材２０周りに回転し難くなり、その周りにおいて一定位置に取付けできる。 In addition, a plurality of reinforcing protrusions 26 and 27 are formed, and the vehicle fixing component 40 is attached to the vehicle fixing component mounting portion 32 in a state where the vehicle fixing component 40 is locked to the reinforcing protrusion 27, so that the vehicle fixing component 40 becomes difficult to rotate around the electric wire exterior member 20, and can be attached to a fixed position around it.
　また、電線外装部材２０が、電線１３の被覆と同程度の柔軟性を有する材料によって形成されているため、電線外装部材２０が柔軟に形成され、電線１３と電線外装部材２０との接触による異音発生を抑制することができる。 Further, since the wire sheathing member 20 is formed of a material having the same degree of flexibility as the covering of the wire 13, the wire sheathing member 20 is formed flexibly, and a difference due to contact between the wire 13 and the wire sheathing member 20 is caused. Sound generation can be suppressed.
　また、電線外装部材２０が、内部に収容される電線１３の被覆のベース樹脂と同じベース樹脂の材料によって形成されているため、電線外装部材２０を低コストで製造できる。 Moreover, since the wire sheathing member 20 is formed of the same base resin material as the base resin covering the wire 13 accommodated therein, the wire sheathing member 20 can be manufactured at low cost.
　ところで、電線外装部材としては、既に説明した要請１～４の他、下記の要請５～９をも満たすことができることが好ましい。 By the way, it is preferable that the wire exterior member can satisfy the following requests 5 to 9 in addition to the requests 1 to 4 already described.
　要請５は、電線の取付コストが安価であることである。 Request 5 is that the installation cost of the electric wire is low.
　要請６は、電線外装部材を保管輸送等する際に、コンパクト化できることである。 Request 6 is that the outer packaging member can be made compact when it is stored and transported.
　要請７は、ワイヤーハーネスの製造拠点と同じ場所で調達可能であることである。特に、ワイヤーハーネスの製造拠点は、全世界に広がっているため、それらの各製造拠点で電線外装部材を現地で製造して調達することができれば、電線外装部材を取付けたワイヤーハーネスを安価に製造することができ、かつ、製造リードタイムを短縮化することも可能となる。 Request 7 is that it can be procured at the same location as the wire harness manufacturing base. In particular, the production bases for wire harnesses are spread all over the world, so if you can manufacture and procure the wire sheathing members locally at those production bases, you can manufacture the wire harness with the wire sheathing member at a low cost. In addition, the manufacturing lead time can be shortened.
　要請８は、車両におけるワイヤーハーネスの使用環境で十分な耐久性を有することである。 Request 8 is to have sufficient durability in the usage environment of the wire harness in the vehicle.
　要請９は、電線の被覆への影響が少ないものであることである。 Request 9 is that there is little influence on the coating of the wire.
　ここで、既に説明した背景技術１～４と要請５～９との関係について説明すると、次のようになる。 Here, the relationship between the background technologies 1 to 4 and the requests 5 to 9 already described will be described as follows.
　すなわち、射出成形されたプロテクタを用いる背景技術１に関しては、要請６を満たすことは難しい。通常、射出成形されたプロテクタは、電線の配設経路等に応じて複雑な形状を有しているため、嵩張る傾向にあるからである。 That is, it is difficult to satisfy the request 6 for the background technology 1 using the injection molded protector. This is because an injection molded protector usually has a complicated shape according to the arrangement route of the electric wire and tends to be bulky.
　また、背景技術１は、要請７～９を満たすことも難しい。プロテクタを射出成形で製造するのに適し、かつ、これらの要請を満たすことができる材料を現地で入手できない可能性があるからである。 Also, it is difficult for Background Art 1 to satisfy Requests 7-9. This is because there is a possibility that a material suitable for manufacturing the protector by injection molding and satisfying these requirements may not be available locally.
　押出成形された角筒状のプロテクタを用いる背景技術２に関しては、要請５を満たすことは難しい。適用箇所が直線箇所に限定されるため、曲る箇所がある場合には複数に分割する必要があり、ワイヤーハーネス全体としてみると複数の部品を取付ける必要が生じ、取付コストが増えてしまうからである。 Regarding Background Art 2 using an extruded rectangular tube protector, it is difficult to satisfy Request 5. Because the application location is limited to a straight location, if there is a bending location, it is necessary to divide it into multiple parts, and it will be necessary to install multiple parts when viewed as a whole wire harness, which increases the installation cost. is there.
　また、背景技術２は、要請７～９を満たすことも難しい。押出成形された角筒状のプロテクタを用いるのに適し、かつ、これらの要請を満たすことができる材料を現地で入手できない可能性があるからである。 Also, it is difficult for Background Art 2 to satisfy Requests 7-9. This is because there is a possibility that a material suitable for using an extruded rectangular tube-shaped protector and satisfying these requirements may not be available locally.
　コルゲートチューブを用いる背景技術３及び硬質チューブを用いる背景技術４は、要請７～９を満たすことは難しい。コルゲートチューブ或は硬質チューブとしての適正を満たし、かつ、これらの要請を満たすことができる材料を現地で入手できない可能性があるからである。 The background technology 3 using a corrugated tube and the background technology 4 using a hard tube are difficult to satisfy the requirements 7-9. This is because there is a possibility that a material satisfying the suitability as a corrugated tube or a hard tube and satisfying these requirements may not be available locally.
　これに対して、本電線外装部材２０では、ワイヤーハーネス１２の経路の直線部分に対しても曲げ部分に対しても分岐部分に対しても１つの部品で対応することができ、また、スリット２１等を介してワイヤーハーネス１２を容易に電線外装部材２０内に収容することできるため、電線の取付コストを安価にできる。これにより、要請５を満たすことができる。 On the other hand, in this electric wire exterior member 20, it can respond to a straight part of a path of wire harness 12, a bent part, and a branched part with one component, and slit 21 Since the wire harness 12 can be easily accommodated in the electric wire exterior member 20 via, etc., the installation cost of the electric wire can be reduced. Thereby, the request 5 can be satisfied.
　また、電線外装部材２０は線状形状であるため保管輸送効率に優れる。また、ロール状に丸めることが可能な程度の柔軟性を付与することで、保管輸送効率をより向上させることできる。このため、要請６を満たす。なお、電線外装部材２０にどの程度の柔軟性を付与するかについては、直線部分での維持性能等を考慮して決定される。 Moreover, since the electric wire exterior member 20 has a linear shape, it is excellent in storage and transportation efficiency. Moreover, storage and transport efficiency can be further improved by imparting flexibility to the extent that it can be rolled. Therefore, request 6 is satisfied. It should be noted that how much flexibility is imparted to the electric wire exterior member 20 is determined in consideration of the maintenance performance at the straight portion.
　また、要請７に関しては、比較的簡易な押出成形装置によって製造することができる。また、材料のベース材料として電線の被覆と同じベース材料を用いることで、当該材料を容易に入手可能である。このため、要請７も満たしやすい。 Further, the request 7 can be manufactured by a relatively simple extrusion molding apparatus. Further, by using the same base material as that of the wire coating as the base material of the material, the material can be easily obtained. For this reason, it is easy to satisfy the request 7.
　さらに、要請８、９についても、材料のベース材料として電線の被覆と同じベース材料を用いることで、容易に満たすことができる。 Furthermore, requests 8 and 9 can be easily satisfied by using the same base material as that of the wire coating as the base material of the material.
　このように、本実施形態に係る電線外装部材２０によると、要請５～９についても、容易に満たすことができる。 Thus, according to the electric wire exterior member 20 according to the present embodiment, the requests 5 to 9 can be easily satisfied.

　電線外装部材２０は、その延在方向において基本的には同じ大きさの収容空間に形成される。ワイヤーハーネス１２が、電線外装部材２０の収容空間内にほぼ一杯に収容できる本数の電線１３を含んでいる場合には、当該ワイヤーハーネス１２は電線外装部材２０の内周面に対して複数箇所で接触する（図９参照）。このため、電線外装部材２０内でワイヤーハーネス１２は動き難く、従って、電線外装部材２０とワイヤーハーネス１２との接触による異音は抑制される。しかしながら、ワイヤーハーネス１２が途中で分岐等すると、ワイヤーハーネス１２に含まれる電線１３の本数がその延在方向において部分的に少なくなる箇所が生じる（図１０参照）。このような場合、ワイヤーハーネス１２は、電線外装部材２０内で容易に動き得る。これにより、電線外装部材２０とワイヤーハーネス１２との接触による異音が発生する可能性が生じる。 The electric wire exterior member 20 is basically formed in an accommodation space of the same size in the extending direction. When the wire harness 12 includes the number of electric wires 13 that can be accommodated almost completely in the accommodation space of the electric wire exterior member 20, the wire harness 12 is disposed at a plurality of locations with respect to the inner peripheral surface of the electric wire exterior member 20. Contact (see FIG. 9). For this reason, the wire harness 12 is difficult to move within the electric wire exterior member 20, and accordingly, abnormal noise due to contact between the electric wire exterior member 20 and the wire harness 12 is suppressed. However, when the wire harness 12 is branched in the middle, a portion where the number of the electric wires 13 included in the wire harness 12 is partially reduced in the extending direction is generated (see FIG. 10). In such a case, the wire harness 12 can easily move within the electric wire exterior member 20. Thereby, the possibility that the noise by the contact of the electric wire exterior member 20 and the wire harness 12 will occur arises.
　ここでは、電線外装部材２０のワイヤーハーネス１２の外径が小さい場合において、電線外装部材２０の延在方向中間部に対してワイヤーハーネス１２を固定する例について説明する。 Here, an example in which the wire harness 12 is fixed to an intermediate portion in the extending direction of the wire sheathing member 20 when the outer diameter of the wire harness 12 of the wire sheathing member 20 is small will be described.
　図１１及び図１２に示す例では、電線外装部材２０に対応する電線外装部材１２０の延在方向の一部に電線固定用開口１２２が形成されている。ここでは、一方側の側板部２５、底板部２３の一側部分及び上板部２４の一側部分にかけて電線固定用開口１２２が形成されている。電線固定用開口１２２は、電線固定用開口１２２の延在方向において、電線固定部品としての粘着テープＴの幅よりも大きく開くように形成されている。 11 and 12, the wire fixing opening 122 is formed in a part of the extending direction of the wire sheathing member 120 corresponding to the wire sheathing member 20. Here, a wire fixing opening 122 is formed over one side plate portion 25, one side portion of the bottom plate portion 23, and one side portion of the upper plate portion 24. The wire fixing opening 122 is formed so as to open larger than the width of the adhesive tape T as the wire fixing component in the extending direction of the wire fixing opening 122.
　そして、電線外装部材１２０内にワイヤーハーネス１２を収容した状態で、電線外装部材１２０のうち電線固定用開口１２２が形成された部分及びワイヤーハーネス１２のうち当該電線固定用開口１２２に露出する部分に、粘着テープＴを巻付ける。すると、巻回された粘着テープＴが、電線固定用開口１２２を通じて内部のワイヤーハーネス１２を電線外装部材１２０内、即ち、他方の側板部２５に向けて押付ける。これにより、ワイヤーハーネス１２が電線外装部材１２０内の一定位置に固定され、ワイヤーハーネス１２が電線外装部材１２０内で動き難くなり、異音の発生等が抑制される。 And in the state which accommodated the wire harness 12 in the electric wire exterior member 120, in the part in which the opening 122 for electric wire fixation was formed among the electric wire exterior members 120, and the part exposed to the said electric wire fixing opening 122 among the wire harnesses 12 Wrap the adhesive tape T. Then, the wound adhesive tape T presses the inner wire harness 12 through the electric wire fixing opening 122 toward the electric wire exterior member 120, that is, toward the other side plate portion 25. Thereby, the wire harness 12 is fixed to a fixed position in the electric wire exterior member 120, the wire harness 12 becomes difficult to move in the electric wire exterior member 120, and the occurrence of abnormal noise is suppressed.
　図１３及び図１４に示す例では、電線外装部材２０に対応する電線外装部材２２０の延在方向の中間部に一対の絞り用スリット２２２が形成されている。一対の絞り用スリット２２２は、電線外装部材２２０の延在方向において間隔をあけて形成されている。また、各絞り用スリット２２２は、電線外装部材２２０の周方向に沿って形成されている。ここでは、絞り用スリット２２２は、一方側の側板部２５及び上板部２４の一側部分に至る部分に形成されている。これにより、電線外装部材２２０のうち一対の絞り用スリット２２２間の部分、即ち、一方側の側板部２５及び上板部２４の一側部分が電線外装部材２２０の内側に変形可能とされている。なお、電線外装部材２２０のうち一対の絞り用スリット２２２の間の部分が電線外装部材２２０の延在方向に沿って切断されていてもよい。これにより、一対の絞り用スリット２２２間の部分を容易に変形させることができる。 In the example shown in FIGS. 13 and 14, a pair of diaphragm slits 222 is formed in the intermediate portion in the extending direction of the wire sheathing member 220 corresponding to the wire sheathing member 20. The pair of diaphragm slits 222 are formed with a gap in the extending direction of the wire sheathing member 220. Each diaphragm slit 222 is formed along the circumferential direction of the electric wire exterior member 220. Here, the diaphragm slit 222 is formed in a portion reaching one side portion of the side plate portion 25 and the upper plate portion 24 on one side. Thereby, a portion between the pair of diaphragm slits 222 in the electric wire exterior member 220, that is, one side portion of the side plate portion 25 and the upper plate portion 24 on one side can be deformed inside the electric wire exterior member 220. . Note that a portion of the wire sheathing member 220 between the pair of drawing slits 222 may be cut along the extending direction of the wire sheathing member 220. Thereby, the part between the pair of diaphragm slits 222 can be easily deformed.
　電線外装部材２２０のうち一対の絞り用スリット２２２に対しては、電線固定部品２３０が取付けられる。電線固定部品２３０は、板状部２３２と、側板部２３４と、押付部２３６とを備える。板状部２３２及び側板部２３４は、上記車両固定用部品４０における板状部４３及び側板部４４と同様構成である。押付部２３６は、板状部４３の一方主面側において、板状部２３２の一側部から板状部２３２の幅方向中央に向けて延出するように形成されている。また、押付部２３６の先端部には、板状部２３２に対して直交する上方向に延びる押付片２３６ａが形成されている。上記板状部２３２と押付部２３６との間には、底板部２３の一側部分及び一方の側板部２５を収容可能な隙間が形成されている。 The electric wire fixing component 230 is attached to the pair of slits 222 for drawing out of the electric wire exterior member 220. The electric wire fixing component 230 includes a plate-like portion 232, a side plate portion 234, and a pressing portion 236. The plate-like portion 232 and the side plate portion 234 have the same configuration as the plate-like portion 43 and the side plate portion 44 in the vehicle fixing component 40. The pressing portion 236 is formed on one main surface side of the plate-like portion 43 so as to extend from one side portion of the plate-like portion 232 toward the center in the width direction of the plate-like portion 232. In addition, a pressing piece 236 a extending in the upward direction perpendicular to the plate-like part 232 is formed at the tip of the pressing part 236. A gap is formed between the plate-like portion 232 and the pressing portion 236 so as to accommodate one side portion of the bottom plate portion 23 and one side plate portion 25.
　そして、板状部２３２及び側板部２３４を、電線外装部材２２０の底板部２３及び他方の側板部２５の外面に接触させて、側板部２３４の先端部を補強用突部２７に係止すると共に、電線外装部材２２０のうち一対の絞り用スリット２２２間の部分を内側に変形させて、上記板状部２３２と押付部２３６との間に、底板部２３の一側部分及び一方の側板部２５を収容させる。これにより、電線固定部品２３０が電線外装部材２２０のうち一対の絞り用スリット２２２間の部分に取付けられると共に、押付部２３６の押付片２３６ａが、一対の絞り用スリット２２２間の部分を内側に向けて変形させた状態に維持し、当該部分を介してワイヤーハーネス１２を内部に向けて押込む。これにより、ワイヤーハーネス１２が電線外装部材２２０内の一定位置に固定され、ワイヤーハーネス１２が電線外装部材２２０内で動き難くなり、異音の発生等が抑制される。 Then, the plate-like portion 232 and the side plate portion 234 are brought into contact with the outer surface of the bottom plate portion 23 and the other side plate portion 25 of the electric wire exterior member 220, and the distal end portion of the side plate portion 234 is locked to the reinforcing protrusion 27. The portion between the pair of diaphragm slits 222 in the electric wire exterior member 220 is deformed inward, so that one side portion of the bottom plate portion 23 and one side plate portion 25 are between the plate-like portion 232 and the pressing portion 236. Contain. As a result, the electric wire fixing component 230 is attached to the portion between the pair of diaphragm slits 222 in the electric wire exterior member 220, and the pressing piece 236a of the pressing portion 236 faces the portion between the pair of diaphragm slits 222 inward. The wire harness 12 is pushed inward through the portion. Thereby, the wire harness 12 is fixed to a fixed position in the electric wire exterior member 220, the wire harness 12 becomes difficult to move in the electric wire exterior member 220, and the occurrence of abnormal noise is suppressed.
　図１３及び図１４に係る構成が適用された電線モジュール２１０は、図１５に示すようになる。すなわち、ワイヤーハーネス１２は、電線外装部材２２０の途中で分岐しているため、その分岐部分の前後で、ワイヤーハーネス１２の外径が異なってしまう可能性がある。そこで、電線外装部材２２０のうち細径のワイヤーハーネス１２を収容する部分に上記一対の絞り用スリット２２２を形成し、ここに電線固定部品２３０を取付けることで、電線固定部品２３０内の一定位置で細径のワイヤーハーネス１２を固定している。 The electric wire module 210 to which the configuration according to FIGS. 13 and 14 is applied is as shown in FIG. That is, since the wire harness 12 is branched in the middle of the electric wire exterior member 220, the outer diameter of the wire harness 12 may be different before and after the branched portion. Therefore, the pair of slits 222 for drawing are formed in a portion of the electric wire exterior member 220 that accommodates the thin wire harness 12, and the electric wire fixing component 230 is attached to the electric wire fixing member 230 at a certain position in the electric wire fixing component 230. A thin wire harness 12 is fixed.
　なお、上記各変形例において、電線固定部品として、上記の他、結束バンド等を用いることもできる。 In addition, in each said modification, a binding band etc. other than the above can also be used as an electric wire fixing component.
　＜電線外装部材の断面形状に関する変形例＞
　電線外装部材の変形例について説明する。 <Modified example regarding cross-sectional shape of electric wire exterior member>
A modification of the electric wire exterior member will be described.
　図１６及び図１７に示す例では、電線外装部材３２０は、角筒状の本体部３２２と、複数の補強用突部３２６とを備える。 16 and 17, the electric wire exterior member 320 includes a rectangular tube-shaped main body 322 and a plurality of reinforcing protrusions 326.
　本体部３２２は、底板部３２３の両側に一対の側板部３２４が立設された収容部３２２ａと、底板部３２３の反対側で一対の側板部３２４間を閉じる蓋部３２２ｂとを備える。一方の側板部３２４と蓋部３２２ｂの一側部とは、薄肉なヒンジ部３２２ｃによって連結されており、蓋部３２２ｂは、収容部３２２ａに対して開閉可能とされている。 The main body portion 322 includes a housing portion 322a in which a pair of side plate portions 324 are erected on both sides of the bottom plate portion 323, and a lid portion 322b that closes the pair of side plate portions 324 on the opposite side of the bottom plate portion 323. One side plate part 324 and one side part of the cover part 322b are connected by a thin hinge part 322c, and the cover part 322b can be opened and closed with respect to the accommodating part 322a.
　かかる電線外装部材３２０も、蓋部３２２ｂが収容部３２２ａを閉じた状態で、電線の周囲全体を囲う多角形の閉断面形状を呈する。なお、補強用突部３２６は、底板部３２３、一対の側板部３２４、蓋部３２２ｂのそれぞれの中央部及び両側の位置に形成されている。 The electric wire exterior member 320 also has a polygonal closed cross-sectional shape surrounding the entire periphery of the electric wire in a state where the lid portion 322b closes the housing portion 322a. Note that the reinforcing protrusions 326 are formed at the center and both sides of the bottom plate 323, the pair of side plates 324, and the cover 322b.
　図１６及び図１７に示す例では、蓋部３２２ｂを開くことで電線外装部材３２０内に容易に電線を収容することができる。なお、蓋部３２２ｂを閉じた状態は、蓋部３２２ｂ及び収容部３２２ａに粘着テープを巻回すること等によって維持することができる。 In the example shown in FIGS. 16 and 17, the electric wire can be easily accommodated in the electric wire exterior member 320 by opening the lid portion 322b. In addition, the state which closed the cover part 322b can be maintained by winding an adhesive tape around the cover part 322b and the accommodating part 322a.
　図１８及び図１９に示す例では、電線外装部材４２０は、上記電線外装部材３２０において、蓋部３２２ｂの他側部にフック部４３０を設け、他方の側板部３２４にフック受部４４０を形成した構成とされている。 In the example shown in FIG. 18 and FIG. 19, the electric wire exterior member 420 is provided with the hook portion 430 on the other side portion of the lid portion 322 b and the hook receiving portion 440 on the other side plate portion 324 in the electric wire exterior member 320. It is configured.
　フック部４３０は、蓋部３２２ｂの他側部から内側に向けて延出するように形成され、その外面側に突出する突部４３０ａが形成されている。 The hook portion 430 is formed so as to extend inward from the other side portion of the lid portion 322b, and a protruding portion 430a protruding to the outer surface side is formed.
　フック受部４４０は、他方の側板部３２４の上端部から外方に突出するように形成されており、その内部に上記フック部４３０を収容可能な凹部４４２が形成されている。また、フック部４３０が凹部４４２内に収容された状態で、突部４３０ａと対向する部分には受面４４２ａが形成されている。そして、フック部４３０が凹部４４２内に収容された状態、突部４３０ａと受面４４２ａとが係止し合うことで、蓋部３２２ｂが閉じた状態に維持されるようになっている。 The hook receiving portion 440 is formed so as to protrude outward from the upper end portion of the other side plate portion 324, and a concave portion 442 capable of accommodating the hook portion 430 is formed therein. In addition, a receiving surface 442a is formed at a portion facing the protrusion 430a in a state where the hook portion 430 is accommodated in the recess 442. And the state where the hook part 430 is accommodated in the recessed part 442, and the protrusion part 430a and the receiving surface 442a latch each other, and the cover part 322b is maintained in the closed state.
　この変形例によると、蓋部３２２ｂを容易に閉じることができるというメリットがある。 This modification has the advantage that the lid 322b can be easily closed.
　また、図２０及び図２１に示す例では、電線外装部材５２０は、角筒状の内側本体部５２２ａと、角筒状の外側本体部５２２ｂと、複数の補強用突部５２６とを備える。 In the example shown in FIGS. 20 and 21, the electric wire exterior member 520 includes a rectangular tube-shaped inner main body 522 a, a rectangular tube-shaped outer main body 522 b, and a plurality of reinforcing protrusions 526.
　内側本体部５２２ａは外側本体部５２２ｂよりも小さく、従って、これらの間に隙間が設けられている。 The inner main body 522a is smaller than the outer main body 522b, and therefore a gap is provided between them.
　複数の補強用突部５２６は、内側本体部５２２ａと外側本体部５２２ｂとの間に介在している。ここでは、各板状部分の中央部及び両側部に補強用突部５２６が形成されている。従って、電線外装部材５２０は、中空構造を有する板部分によって囲まれた形状ともいえる。このように、電線外装部材５２０が中空構造を有する板部材によって形成されることで、電線の保護性能を向上させることができる。 The plurality of reinforcing protrusions 526 are interposed between the inner main body 522a and the outer main body 522b. Here, reinforcing protrusions 526 are formed at the center and both sides of each plate-like portion. Therefore, it can be said that the electric wire exterior member 520 has a shape surrounded by a plate portion having a hollow structure. Thus, the electric wire exterior member 520 is formed of a plate member having a hollow structure, whereby the protection performance of the electric wire can be improved.
　また、本変形例では、電線を収容可能な収容部５２１ａと蓋部５２１ｂとがヒンジ部５２１ｃを介して開閉可能に連結された構成とされている。このため、図１６及び図１７に示す変形例と同様に、収容部５２１ａ内に電線を収容することができる。なお、蓋部５２１ｂを閉じた状態で、上記と同様に、粘着テープ等を用いて維持することができる。勿論、図１８及び図１９に示す例と同様に、フック部及びフック受部等を用いた係止構造によって、蓋部を閉じた状態が維持されてもよい。 Moreover, in this modification, it is set as the structure by which the accommodating part 521a which can accommodate an electric wire, and the cover part 521b were connected so that opening and closing was possible via the hinge part 521c. For this reason, an electric wire can be accommodated in the accommodating part 521a similarly to the modification shown in FIG.16 and FIG.17. In addition, in the state which closed the cover part 521b, it can maintain using an adhesive tape etc. similarly to the above. Of course, similarly to the example shown in FIGS. 18 and 19, the state in which the lid portion is closed may be maintained by the locking structure using the hook portion and the hook receiving portion.
　なお、上記各変形例に係る電線外装部材３２０、４２０、５２０も、追加加工で形成される切離部等を除いて、その延在方向において同一断面形状を呈するように形成されている。 In addition, the electric wire exterior members 320, 420, and 520 according to each of the above modifications are also formed so as to exhibit the same cross-sectional shape in the extending direction except for a separation portion formed by additional processing.
　なお、上記実施形態及び各変形例で説明した各構成は、相互に矛盾しない限り適宜組合わせることができる。 In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.
　以上のようにこの発明は詳細に説明されたが、上記した説明は、すべての局面において、例示であって、この発明がそれに限定されるものではない。例示されていない無数の変形例が、この発明の範囲から外れることなく想定され得るものと解される。 Although the present invention has been described in detail as described above, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
