(6) 上記(4)又は(5)に記載のワイヤハーネスにおいて、前記二つの壁は、壁外面を外側へ変形させ且つ該外側への変形に伴って壁内面も追従するように変形させてなる変形部を有する。 (6) In the wire harness described in (4) or (5) above, the two walls are deformed so that the outer surface of the wall is deformed outward and the inner surface of the wall is also tracked along with the deformation of the outer wall. It has the deformation part which becomes.
 上記(1)によれば、外装部材に関し、導電路の延在方向に低剛性部と高剛性部とを連続させた構造のものを採用することから、従来のような複数種の外装部材を用いたり、また、複数種のうちの例えば一種を更に複数個用いたりする必要がなく、そのため部品点数を最小限に抑えることができる。従って、本発明によれば、上記構造の外装部材を採用することにより、コストや工数の低減を図ることができるという効果を奏する。また、部品管理を容易にすることができるという効果も奏する。 According to the above (1), with respect to the exterior member, since the one having a structure in which the low-rigidity portion and the high-rigidity portion are continuous in the extending direction of the conductive path is adopted, a plurality of types of conventional exterior members are used. In addition, it is not necessary to use a plurality of, for example, one of a plurality of types, so that the number of parts can be minimized. Therefore, according to this invention, there exists an effect that reduction of cost and a man-hour can be aimed at by employ | adopting the exterior member of the said structure. In addition, there is an effect that parts management can be facilitated.
 上記(2)によれば、上記(1)の効果に加え、次のような効果も奏する。すなわち、本発明のワイヤハーネスは車両床下を通る長尺なものであり、この長尺なワイヤハーネスに用いられる外装部材は、車両床下の位置に合わせて高剛性部を配置する構造であることから、ワイヤハーネスの配索作業時(取り付け作業時)に不必要な撓みを抑えることができる。従って、作業性の向上を図ることができるという効果を奏する。 According to the above (2), in addition to the effect of (1), the following effect is also achieved. That is, the wire harness of the present invention is a long one that passes under the vehicle floor, and the exterior member used for the long wire harness has a structure in which a high-rigidity portion is arranged in accordance with the position under the vehicle floor. Unnecessary bending can be suppressed at the time of wiring harness wiring operation (attachment operation). Therefore, there is an effect that workability can be improved.
 上記(3)によれば、上記(2)の効果に加え、次のような効果も奏する。すなわち、高剛性部は、車両床下に対向する側と地面に対向する側とに配置される平行な二つの壁を有することから、このような外装部材であれば、例えば断面円形状の外装部材と比べ、構造上、地面からワイヤハーネスを遠ざけることができる。言い換えれば、低背化を図ることができる。従って、地面側からの影響を受け難くすることができるという効果を奏する。また、ワイヤハーネスとしての機能や信頼性を維持することができるという効果も奏する。 According to the above (3), in addition to the effect of (2), the following effect is also achieved. That is, since the high-rigidity portion has two parallel walls arranged on the side facing the vehicle floor and the side facing the ground, such an exterior member is, for example, an exterior member having a circular cross section. Compared to the structure, the wire harness can be kept away from the ground. In other words, the height can be reduced. Therefore, there is an effect that it is difficult to be influenced by the ground side. In addition, the function and reliability of the wire harness can be maintained.
 上記(4)によれば、上記(3)の効果に加え、次のような効果も奏する。すなわち、高剛性部は、二つの支持壁を有することから、二つの壁の配置を維持するような状態にこれらを支持することができる。また、二つの支持壁は対称であることから、安定した状態で二つの壁を支持することができる。従って、破損し難い構造の高剛性部にすることができるという効果を奏する。また、高剛性部に十分な強度を持たせることができるという効果も奏する。 According to the above (4), in addition to the effect of (3), the following effect is also achieved. That is, since the high-rigidity part has two support walls, these can be supported in a state in which the arrangement of the two walls is maintained. Further, since the two support walls are symmetric, the two walls can be supported in a stable state. Therefore, it is possible to obtain a highly rigid portion having a structure that is not easily damaged. In addition, there is an effect that the high rigidity portion can be given sufficient strength.
 上記(5)によれば上記(4)の効果に加え、次のような効果も奏する。すなわち、対称な二つの支持壁の形状は、外側へ膨らむ湾曲形状であることから、外装部材を樹脂製とする場合、例えば膨らまない形状(二つの壁に垂直な形状)と比べ、離型性を良くすることができる。従って、製造性の良い外装部材にすることができるという効果を奏する。 According to the above (5), in addition to the effect of (4), the following effect is also achieved. In other words, the two symmetrical support wall shapes are curved shapes that bulge outward, so that when the exterior member is made of resin, for example, the mold release property is less than the shape that does not bulge (shape perpendicular to the two walls). Can be improved. Therefore, there is an effect that the exterior member can be manufactured with good manufacturability.
 上記(6)によれば、上記(4)又は(5)の効果に加え、次のような効果も奏する。すなわち、車両床下に対向する側と地面に対向する側とに配置される平行な二つの壁は、壁外面を外側へ変形させる変形部を有することから、この変形部により強度を持たせることができる。従って、破損し難い構造の高剛性部にすることができるという効果を奏する。また、高剛性部に十分な強度を持たせることができるという効果も奏する。 According to (6) above, in addition to the effects of (4) or (5), the following effects are also achieved. That is, since two parallel walls arranged on the side facing the vehicle floor and the side facing the ground have a deformed portion that deforms the outer surface of the wall outward, it is possible to give strength to the deformed portion. it can. Therefore, it is possible to obtain a highly rigid portion having a structure that is not easily damaged. In addition, there is an effect that the high rigidity portion can be given sufficient strength.
 また、変形部は、外側への変形に伴って壁内面も追従する形状になることから、外装部材を樹脂製とする場合、例えば壁内面側を追従させない形状と比べ、樹脂量を少なくすることができる。このように樹脂量を少なくすることができれば、成形時の冷却も早くすることができる。従って、成形スピードを速くすることができ、以て製造性の良い外装部材にすることができるという効果を奏する。 In addition, since the deformed portion has a shape that also follows the wall inner surface as it deforms outward, when the exterior member is made of resin, for example, the amount of resin should be reduced compared to a shape that does not follow the wall inner surface side. Can do. If the amount of resin can be reduced in this way, cooling during molding can be accelerated. Therefore, it is possible to increase the molding speed and to produce an exterior member with good manufacturability.
 さらに、変形部は、上記の変形により表面積を大きくすることができる。従って、成形時の冷却を早くしたり、使用時の放熱性を高めたりすることができるという効果を奏する。 Furthermore, the surface area of the deformed portion can be increased by the above deformation. Therefore, there is an effect that the cooling at the time of molding can be accelerated, and the heat dissipation at the time of use can be enhanced.

It is assumed that the hybrid vehicle 1 can use a power storage device such as a capacitor instead of the battery 5. The battery 5 is not particularly limited as long as it can be used for the hybrid vehicle 1 and the electric vehicle.
 図2において、ワイヤハーネス9は、高圧導電路15(導電路)と、この高圧導電路15を収容保護する外装部材16と、高圧導電路15の端末に設けられるシールドコネクタ(図示省略)と、外装部材16の外面に取り付けられる複数のクランプ(図示省略)及びグロメット等とを備えて構成される。 In FIG. 2, the wire harness 9 includes a high-voltage conductive path 15 (conductive path), an exterior member 16 that accommodates and protects the high-voltage conductive path 15, a shield connector (not shown) provided at the end of the high-voltage conductive path 15, A plurality of clamps (not shown) attached to the outer surface of the exterior member 16 and grommets are configured.
 尚、ワイヤハーネス9は、高圧導電路15と一緒に低圧導電路も外装部材16に収容保護するような構成及び構造としてもよいものとする。 The wire harness 9 may be configured and structured so that the low voltage conductive path and the high voltage conductive path 15 are accommodated and protected by the exterior member 16.
 図2及び図3において、高圧導電路15は、二本の高圧回路17と、この二本の高圧回路17を覆うシールド部材18と、シールド部材18の外側に設けられるシース19とを備えて構成される(一例であるものとする)。 2 and 3, the high-voltage conductive path 15 includes two high-voltage circuits 17, a shield member 18 that covers the two high-voltage circuits 17, and a sheath 19 that is provided outside the shield member 18. (Assumed to be an example).
 高圧回路17は、ここでは公知の高圧電線であって、導体20と、この導体20を被覆する絶縁体21とを備えて構成される。高圧回路17は、電気的な接続に必要な長さを有するように形成される。高圧回路17は、ワイヤハーネス9がインバータユニット4とバッテリー5(ジャンクションブロック12)とを電気的に接続する(図1参照)ことから、長尺なものに形成される。 Here, the high voltage circuit 17 is a known high voltage electric wire, and includes a conductor 20 and an insulator 21 covering the conductor 20. The high voltage circuit 17 is formed to have a length necessary for electrical connection. The high voltage circuit 17 is formed in a long shape because the wire harness 9 electrically connects the inverter unit 4 and the battery 5 (junction block 12) (see FIG. 1).
 導体20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20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。導体20の外面には、絶縁性の樹脂材料からなる絶縁体21が押出成形される。 The conductor 20 is made of copper, copper alloy, aluminum, or aluminum alloy. The conductor 20 has a conductor structure in which strands are twisted or a bar-like conductor structure having a rectangular or round cross section (for example, a conductor structure having a flat single core or a single round core, in which case the wire itself Can also be any of those having a rod shape. An insulator 21 made of an insulating resin material is extruded on the outer surface of the conductor 20.
 尚、高圧回路17として、本実施例では公知の高圧電線の構成を採用するが、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ものとする。 In addition, although the structure of a well-known high voltage electric wire is employ | adopted as a high voltage circuit 17 in a present Example, it shall not be this limitation. That is, a known bus bar with an insulator provided as a high voltage circuit may be employed.
 シールド部材18は、二本の高圧回路17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18は、二本の高圧回路17の全長とほぼ同じ長さに形成される。シールド部材18は、この端部が上記シールドコネクタ(図示省略)を介してインバータユニット4(図1参照)のシールドケース等(図示省略)に接続される。 The shield member 18 is a member for electromagnetic shielding (shield member for electromagnetic waves) that collectively covers the two high-voltage circuits 17, and a known braid formed by knitting a large number of strands into a cylindrical shape is adopted. The The shield member 18 is formed to have substantially the same length as the entire length of the two high-voltage circuits 17. The end of the shield member 18 is connected to a shield case or the like (not shown) of the inverter unit 4 (see FIG. 1) via the shield connector (not shown).
 シールド部材18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ものとする。 The shield member 18 may adopt, for example, a conductive metal foil or a member including this metal foil as long as it can take countermeasures against electromagnetic waves.
 シース19は、絶縁性を有する樹脂材料を所定の厚さでシールド部材18の外側に押出成形してなるものであり、高圧導電路15の最外層となる位置に配置される。尚、本実施例においては導電路構成にシース19が含まれているが、シース19を設けずにシールド部材18を最外層に位置に配置してもよいものとする。 The sheath 19 is formed by extruding an insulating resin material with a predetermined thickness to the outside of the shield member 18, and is disposed at a position to be the outermost layer of the high-voltage conductive path 15. In the present embodiment, the sheath 19 is included in the conductive path configuration, but the shield member 18 may be disposed in the outermost layer without providing the sheath 19.
 また、高圧導電路15の代わりに、公知のシールド電線を用いてもよい。この場合においても、本数は一又は複数本であるものとする。また、一本でプラス回路及びマイナス回路を同軸で有するように、或いは一本で三回路以上を同軸で有するように構成される高圧同軸複合導電路(図示省略)等を用いてもよい。 In addition, a known shielded electric wire may be used instead of the high voltage conductive path 15. Even in this case, the number is one or more. Alternatively, a high-voltage coaxial composite conductive path (not shown) or the like configured to have a single plus circuit and a minus circuit coaxially, or to have three or more circuits coaxially may be used.
 図2及び図3において、外装部材16は、上記高圧導電路15を覆う樹脂製の管体であって、高圧導電路15の挿通収容に必要な長さ、及び保護に必要な厚みを有する形状に形成される。外装部材16は、車両床下11(図1参照)を通りこの車両床下11の前後に跨る長尺なものとして形成される。尚、外装部材16は、後述する低剛性部24及び高剛性部25を有するのであれば、樹脂製に限らず金属製であってもよいものとする。 2 and 3, the exterior member 16 is a resin tube covering the high-voltage conductive path 15 and has a shape necessary for insertion and accommodation of the high-voltage conductive path 15 and a thickness necessary for protection. Formed. The exterior member 16 is formed as an elongate member passing through the vehicle underfloor 11 (see FIG. 1) and straddling the front and rear of the vehicle underfloor 11. The exterior member 16 is not limited to resin and may be made of metal as long as it has a low rigidity portion 24 and a high rigidity portion 25 described later.
 外装部材16は、外面22及び内面23を有している。外装部材16は、撓み可能な低剛性部24と、この低剛性部24よりも剛性の高い高剛性部25とを有して図2に示す如くの形状に形成される。具体的には、高圧導電路15の延在方向に低剛性部24と高剛性部25とを連続させるような形状に形成される。外装部材16は、低剛性部24と高剛性部25とをそれぞれ複数有し、これらを交互に配置して連続形成される。外装部材16は、低剛性部24を撓ませない状態でこの低剛性部24と高剛性部25とを直線状にするように樹脂成形される。 The exterior member 16 has an outer surface 22 and an inner surface 23. The exterior member 16 has a low-rigidity portion 24 that can be bent and a high-rigidity portion 25 that is higher in rigidity than the low-rigidity portion 24 and is formed in a shape as shown in FIG. Specifically, the low-rigidity portion 24 and the high-rigidity portion 25 are formed in a shape that is continuous in the extending direction of the high-voltage conductive path 15. The exterior member 16 has a plurality of low-rigidity portions 24 and high-rigidity portions 25, respectively, and these are alternately arranged to be continuously formed. The exterior member 16 is resin-molded so that the low-rigidity portion 24 and the high-rigidity portion 25 are linear without bending the low-rigidity portion 24.
 低剛性部24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)に合わせて配置形成される。具体的には、低剛性部24は、曲げの必要な区間に合わせて配置される。また、低剛性部24は、曲げに必要な長さを有するように形成される。この他、本実施例の低剛性部24は、断面略矩形状に形成される。低剛性部24は、ワイヤハーネス9の製造後となる、梱包時や輸送時、車両への経路配索時(取り付け時)に、それぞれ所望の角度で撓ませることができるように形成される(図示省略)。 The low-rigidity portion 24 is arranged and formed according to the vehicle mounting shape (the shape of the wire harness wiring destination. The shape to be fixed). Specifically, the low-rigidity portion 24 is arranged in accordance with a section that needs to be bent. The low rigidity portion 24 is formed to have a length necessary for bending. In addition, the low-rigidity portion 24 of this embodiment is formed in a substantially rectangular cross section. The low-rigidity portion 24 is formed so as to be able to be bent at a desired angle at the time of packaging, transportation, and route routing to the vehicle (at the time of attachment) after the manufacture of the wire harness 9 ( (Not shown).
 低剛性部24は、撓ませて所望の曲げ形状にすることができるとともに、元のストレートな形状に戻すことも当然にできるものとする。 The low-rigidity portion 24 can be bent to have a desired bent shape and can be naturally returned to the original straight shape.
 低剛性部24は、本実施例において蛇腹管形状に形成される。なお、可撓性を有すれば形状は特に限定されない。具体的には、周方向に形成される凹部26及び凸部27を有するとともに、これら凹部26及び凸部27が管軸方向(高圧導電路15の延在方向)に交互に連続するように複数配置される。 The low rigidity portion 24 is formed in a bellows tube shape in this embodiment. Note that the shape is not particularly limited as long as it has flexibility. Specifically, a plurality of concave portions 26 and convex portions 27 formed in the circumferential direction are provided, and the concave portions 26 and the convex portions 27 are alternately arranged in the tube axis direction (extending direction of the high-voltage conductive path 15). Be placed.
 上記説明からも分かるように、低剛性部24の配置部分は、恰もコルゲートチューブとなる形状に形成される。言い換えれば、外装部材16は、部分的にコルゲートチューブを有する形状に形成される。外装部材16は、上記の如くコルゲートチューブの部分を有することから、「コルチューブ」や「部分形成コルゲートチューブ」などと呼ぶことができる。 As can be seen from the above description, the arrangement portion of the low-rigidity portion 24 is formed into a shape that becomes a corrugated tube. In other words, the exterior member 16 is partially formed in a shape having a corrugated tube. Since the exterior member 16 has a corrugated tube portion as described above, it can be called a “cortube” or a “partially formed corrugated tube”.
 一方、高剛性部25は、ワイヤハーネス9の梱包時や輸送時、経路配索時に曲がらない部分として形成される。なお、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。また、高剛性部25は、断面略矩形状のストレートチューブ形状に形成される。高剛性部25は、上記車両取付形状に合わせた位置や長さに形成される。高剛性部25は、上記の如くストレートチューブ形状(直管形状)に形成されることから、「ストレート部」や「直管部」などと呼ぶことができる。 On the other hand, the high-rigidity portion 25 is formed as a portion that does not bend when the wire harness 9 is packed, transported, or routed. In addition, the part which does not bend means the part which does not give flexibility positively. The high-rigidity portion 25 is formed in a straight tube shape having a substantially rectangular cross section. The high-rigidity portion 25 is formed at a position and length that match the vehicle mounting shape. Since the high-rigidity portion 25 is formed in a straight tube shape (straight tube shape) as described above, it can be referred to as a “straight portion” or a “straight tube portion”.
 断面略矩形状の高剛性部25は、平行な一対の長辺側壁部28(平行な二つの壁)と、対称な一対の短辺側壁部29(対称な二つの支持壁)とを有する。一対の長辺側壁部28は、図3の断面状態で見ると水平方向にのびるように形成される。実際には、図3における上側が車両床下11(図1参照)に対向するように、また、図3における下側が地面に対向するように形成される。 The high rigidity portion 25 having a substantially rectangular cross section has a pair of parallel long side wall portions 28 (two parallel walls) and a pair of symmetrical short side wall portions 29 (two symmetric support walls). The pair of long side wall portions 28 are formed to extend in the horizontal direction when viewed in the cross-sectional state of FIG. In practice, the upper side in FIG. 3 is formed so as to face the vehicle floor 11 (see FIG. 1), and the lower side in FIG. 3 is formed to face the ground.
 一対の短辺側壁部29は、図3の垂直方向にのびるように形成される。また、一対の短辺側壁部29は、それぞれ互いに離隔する向き、即ち外側へ膨らむ若干湾曲した形状に形成される。なお、湾曲形状の他には、例えば「く」字状となる形状であってもよい。但し、十分な支持力を確保することが前提である。このような一対の短辺側壁部29は、一対の長辺側壁部28を支持するように形成される。一対の短辺側壁部29は、例えば地面側からの外力に対し高剛性部25を強くするように形成される。 The pair of short side wall portions 29 are formed so as to extend in the vertical direction of FIG. The pair of short side wall portions 29 are formed in directions that are spaced apart from each other, that is, in a slightly curved shape that bulges outward. In addition to the curved shape, for example, a “<” shape may be used. However, it is premised on ensuring sufficient support. Such a pair of short side wall portions 29 is formed to support the pair of long side wall portions 28. The pair of short side wall portions 29 is formed so as to strengthen the high-rigidity portion 25 against an external force from the ground side, for example.
 尚、図3中の二点差線PLをパーティングライン、矢印Q、Rを型割方向とすると、一対の短辺側壁部29は、この形状が抜き勾配の付いた離型性の良い形状であることが分かる。比較例として真っ直ぐな壁(図示省略。一対の長辺側壁部28に垂直となるような壁)を挙げると、真っ直ぐな壁では抜き勾配がないことから、成形に時間が掛かってしまう。本実施例では、一対の長辺側壁部28が抜き勾配の付いた形状になることから、離型性が良く、そのため成形時間は短くて済むことになる。 If the two-dot difference line PL in FIG. 3 is the parting line and the arrows Q and R are the parting direction, the pair of short side wall portions 29 is a shape with a good releasability with a draft. I understand that there is. If a straight wall (not shown; a wall perpendicular to the pair of long side wall portions 28) is given as a comparative example, the straight wall does not have a draft, so that it takes time to form. In this embodiment, since the pair of long side wall portions 28 have a drafted shape, the releasability is good, and therefore the molding time can be shortened.
 複数の高剛性部25のうち、車両床下11(図1参照)に取り付けされるものは長尺に形成される。長尺に形成された高剛性部25は、例えばリーンホースに沿わせるように取り付けられる。 Among the plurality of high-rigidity portions 25, those attached to the vehicle floor 11 (see FIG. 1) are formed in a long shape. The long and highly rigid portion 25 is attached, for example, along a lean hose.
 上記構成及び構造を有するワイヤハーネス9は次のようにして製造される(図示省略)。すなわち、ワイヤハーネス9は、全体が略直線状に樹脂成形された外装部材16の一端から他端へと高圧導電路15を挿通す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16の外面所定位置にクランプやグロメットやブーツ等を取り付けることにより製造される。さらに、ワイヤハーネス9は、シールドコネクタを高圧導電路15の端末部分に設けることにより製造される。 The wire harness 9 having the above configuration and structure is manufactured as follows (not shown). That is, the wire harness 9 is manufactured by inserting the high-voltage conductive path 15 from one end to the other end of the exterior member 16 that is entirely resin-molded in a substantially linear shape. The wire harness 9 is manufactured by attaching a clamp, a grommet, a boot or the like to a predetermined position on the outer surface of the exterior member 16. Furthermore, the wire harness 9 is manufactured by providing a shield connector at the terminal portion of the high-voltage conductive path 15.
 上記の如く製造された後は、所定の低剛性部24を折り畳むようにして曲げを施すと、ワイヤハーネス9の梱包が完了する。梱包状態のワイヤハーネス9はコンパクトであり、このようなコンパクトな状態で車両組み付け現場まで輸送される。 After being manufactured as described above, when the predetermined low-rigidity portion 24 is folded and bent, the packaging of the wire harness 9 is completed. The packaged wire harness 9 is compact, and is transported to the vehicle assembly site in such a compact state.
 車両組み付け現場では、車両床下11(図1参照)に対応する長尺な部分からワイヤハーネス9は車両に取り付けられる。ワイヤハーネス9は、車両床下11に対応する長尺な部分に外装部材16の高剛性部25が配置されることから、ワイヤハーネス9は撓みを抑えた状態で取り付けられる。この時、ワイヤハーネス9は作業性良く取り付けられる。車両床下11に対応する長尺な部分がクランプ等で固定された後には、外装部材16における低剛性部24の部分を撓ませつつ(曲げつつ)残りの部分が取り付けられる。取り付けに係る一連の作業が完了すると、ワイヤハーネス9は所望の経路で配索された状態になる。 At the vehicle assembly site, the wire harness 9 is attached to the vehicle from a long portion corresponding to the vehicle underfloor 11 (see FIG. 1). Since the high-rigidity portion 25 of the exterior member 16 is disposed in a long portion corresponding to the vehicle underfloor 11, the wire harness 9 is attached in a state in which bending is suppressed. At this time, the wire harness 9 is attached with good workability. After the long portion corresponding to the vehicle lower floor 11 is fixed with a clamp or the like, the remaining portion is attached while bending (bending) the portion of the low-rigidity portion 24 in the exterior member 16. When a series of operations related to attachment is completed, the wire harness 9 is routed along a desired route.
 以上、図1ないし図3を参照しながら説明してきたように、本実施例に係るワイヤハーネス9は、高圧導電路15と外装部材16とを含み、外装部材16に関しては、高圧導電路15の延在方向に低剛性部24と高剛性部25とを連続させた構造のものが採用される。外装部材16が採用されることから、従来のような複数種の外装部材を用いたり、また、複数種のうちの例えば一種を更に複数個用いたりする必要はない。そのため、従来に比べ部品点数を最小限に抑えることができる。従って、上記構造の外装部材16により、コストや工数の低減を図ることができるという効果を奏する。また、部品管理を容易にすることができるという効果も奏する。 As described above with reference to FIGS. 1 to 3, the wire harness 9 according to the present embodiment includes the high-voltage conductive path 15 and the exterior member 16. A structure in which the low-rigidity portion 24 and the high-rigidity portion 25 are continuous in the extending direction is employed. Since the exterior member 16 is employed, there is no need to use a plurality of types of exterior members as in the prior art, or to further use, for example, a plurality of types of the plurality of types. Therefore, the number of parts can be minimized as compared with the conventional case. Therefore, the exterior member 16 having the structure described above has an effect that costs and man-hours can be reduced. In addition, there is an effect that parts management can be facilitated.
 また、本実施例に係るワイヤハーネス9は、外装部材16に関し、車両床下11に対応する長尺な部分に高剛性部25が配置されることから、撓みを抑えた状態で作業性良くワイヤハーネス9の取り付けをすることができる。従って、作業性の向上を図ることができるという効果を奏する。 Further, the wire harness 9 according to the present embodiment is a wire harness with good workability in a state in which bending is suppressed since the high-rigidity portion 25 is disposed in the long portion corresponding to the vehicle underfloor 11 with respect to the exterior member 16. 9 can be attached. Therefore, there is an effect that workability can be improved.
 また、本発明に係るワイヤハーネス9は、外装部材16の高剛性部25に関し、この断面形状を略矩形状にすることから、例えば断面円形状の場合と比べて低背化を図ることができる。従って、車両床下11に高剛性部25を配置すれば、地面側からの影響を受け難くすることができるという効果を奏する。また、ワイヤハーネス9としての機能や信頼性を維持することができるという効果も奏する。 In addition, the wire harness 9 according to the present invention can reduce the height of the high-rigidity portion 25 of the exterior member 16 compared to, for example, a circular cross-section because the cross-sectional shape is substantially rectangular. . Therefore, if the highly rigid part 25 is arrange | positioned under the vehicle floor 11, there exists an effect that it can make it difficult to receive the influence from the ground side. In addition, the function and reliability of the wire harness 9 can be maintained.
 また、本発明に係るワイヤハーネス9は、外装部材16の高剛性部25に関し、一対の長辺側壁部28と一対の短辺側壁部29とを有する構造であることから、破損し難い構造にすることができるという効果を奏する。また、十分な強度を持たせることができるという効果や、離型性を良くして製造性を向上させることができるという効果も奏する。 In addition, the wire harness 9 according to the present invention has a structure having a pair of long side wall portions 28 and a pair of short side wall portions 29 with respect to the high rigidity portion 25 of the exterior member 16, so that the structure is not easily damaged. There is an effect that can be done. Moreover, the effect that it can give sufficient intensity | strength and the effect that a mold release property can be improved and manufacturability can be improved are also show | played.
 以下、図面を参照しながら実施例2を説明する。図4は変形例としてのワイヤハーネスの斜視図である。また、図5は図4のB-B線断面図である。 Hereinafter, Example 2 will be described with reference to the drawings. FIG. 4 is a perspective view of a modified wire harness. FIG. 5 is a sectional view taken along line BB in FIG.
 図4及び図5において、ワイヤハーネス9は、実施例1と同じ高圧導電路15(導電路)と、この高圧導電路15を収容保護する外装部材16等とを備えている。外装部材16は、可撓性を有する複数の低剛性部24と、この低剛性部24のような可撓性を積極的に持たない複数の高剛性部25とを有して、例えば図示形状に形成される。 4 and 5, the wire harness 9 includes the same high-voltage conductive path 15 (conductive path) as that of the first embodiment, and an exterior member 16 that accommodates and protects the high-voltage conductive path 15. The exterior member 16 includes a plurality of low-rigidity portions 24 having flexibility and a plurality of high-rigidity portions 25 that do not actively have flexibility, such as the low-rigidity portions 24. Formed.
 高剛性部25は、平行な一対の長辺側壁部28(平行な二つの壁)と、対称な一対の短辺側壁部29(対称な二つの支持壁)とを有し、一対の長辺側壁部28には、複数の変形部30が形成される。変形部30は、壁外面31を外側へ変形させるとともに、この外側への変形に伴って壁内面32も追従するように変形させて形成される。変形部30は、管軸方向(高圧導電路15の延在方向)に沿って真っ直ぐな形状に形成される。尚、変形部30における引用符号33は凸形状部、引用符号34は凹形状部を示す。 The high rigidity portion 25 has a pair of parallel long side wall portions 28 (two parallel walls) and a pair of symmetrical short side wall portions 29 (two symmetric support walls). A plurality of deformation portions 30 are formed on the side wall portion 28. The deformation portion 30 is formed by deforming the outer wall surface 31 outward and by deforming the outer wall surface 32 so as to follow the outer deformation. The deformable portion 30 is formed in a straight shape along the tube axis direction (extending direction of the high-voltage conductive path 15). Note that the reference numeral 33 in the deformable portion 30 indicates a convex portion, and the reference numeral 34 indicates a concave portion.
 高剛性部25は、上記管軸方向の変形部30の他に、周方向の変形部35も複数有する。変形部35は、一対の長辺側壁部28と一対の短辺側壁部29とに跨って、言い換えれば全周にわたって形成される。変形部35は、形成方向が違うだけで変形部30と同じ形状に形成される。 The high-rigidity portion 25 has a plurality of circumferentially deformable portions 35 in addition to the deformable portion 30 in the tube axis direction. The deforming portion 35 is formed across the pair of long side wall portions 28 and the pair of short side wall portions 29, in other words, over the entire circumference. The deformation part 35 is formed in the same shape as the deformation part 30 only in the formation direction.
 上記構成及び構造において、本実施例に係るワイヤハーネス9は、外装部材16の高剛性部25に関し、変形部30を有することから、強度を持たせることができる。従って、破損し難い構造にすることができるという効果や、十分な強度を持たせることができるという効果を奏する。 In the above configuration and structure, the wire harness 9 according to the present embodiment includes the deformed portion 30 with respect to the high-rigidity portion 25 of the exterior member 16, and thus can be given strength. Therefore, there is an effect that it is possible to make the structure difficult to break, and an effect that sufficient strength can be provided.
 また、変形部30及び変形部35は、外側への変形に伴って壁内面32も追従する形状であることから、例えば凹形状部34が生じない場合と比べ、樹脂量を少なくすることができる。このように樹脂量を少なくすることができれば、成形時の冷却も早くすることができる。従って、成形スピードを速くすることができ、以て製造性の良い外装部材16にすることができるという効果を奏する。 Moreover, since the deformation | transformation part 30 and the deformation | transformation part 35 are the shapes which follow the wall inner surface 32 with the deformation | transformation to an outer side, compared with the case where the concave shape part 34 does not arise, for example, the amount of resin can be decreased. . If the amount of resin can be reduced in this way, cooling during molding can be accelerated. Therefore, it is possible to increase the molding speed, thereby producing the exterior member 16 with good manufacturability.
 さらに、変形部30及び変形部35は、上記の変形により表面積を大きくすることができる。従って、成形時の冷却を早くしたり、使用時の放熱性を高めたりすることができるという効果を奏する。 Furthermore, the deformation part 30 and the deformation part 35 can increase the surface area by the above deformation. Therefore, there is an effect that the cooling at the time of molding can be accelerated, and the heat dissipation at the time of use can be enhanced.
 尚、変形部30は、例えばクランプ等の後付け部品の取り付け位置を認識させる部分としても有効である。 In addition, the deformation | transformation part 30 is effective as a part which recognizes the attachment position of retrofit components, such as a clamp, for example.
 この他、本発明は本発明の主旨を変えない範囲で種々変更実施可能なことは勿論である。 Of course, the present invention can be variously modified without departing from the spirit of the present invention.
