The front cover 35 is an extruded material extruded in the extending direction. The front side cover 35 covers the first electric wire 31 from the front side surface side of the central cover 34. The front cover 35 has a contact flat portion 35a as a contact portion that comes into contact with the first electric wire 31 and sandwiches the first electric wire 31 with the central cover 34. The contact flat portion 35a is formed in a flat plate shape, and is a flat surface of the first electric wire 31. Specifically, the contact flat portion 35a is in surface contact with the flat surface on the side opposite to the side in which the central cover 34 is in surface contact. Further, the front side cover 35 has a side plate portion 35b that bends from both sides of the contact flat portion 35a and extends toward the central cover 34 side to cover the side portion of the first electric wire 31 and separate from the side portion. The front side cover 35 is set so that the side plate portion 35b is separated from the side portion of the first electric wire 31 by forming the width of the contact flat portion 35a larger than the width of the first electric wire 31. Further, the front cover 35 has a fastening portion 35c extending outward in the width direction from the tip of the side plate portion 35b. The fastening portion 35c of the front cover 35 is provided at a position where it overlaps the fastening portion 34a of the central cover 34 in the vertical direction.
　裏側カバー３６は、金属製である。裏側カバー３６は、延在方向に押し出し成形された押し出し材である。裏側カバー３６は、中央カバー３４の裏側面側から第２電線３２を覆う。裏側カバー３６は、第２電線３２と当接して該第２電線３２を中央カバー３４とで挟む当接部としての当接平坦部３６ａを有する。当接平坦部３６ａは、平板状に形成されており、第２電線３２の扁平面であって、詳しくは中央カバー３４が面接触する側とは反対側の扁平面と面接触される。また、裏側カバー３６は、当接平坦部３６ａの両側から屈曲して中央カバー３４側に延びて第２電線３２の側部を覆い且つ該側部から離間する側板部３６ｂを有する。裏側カバー３６は、当接平坦部３６ａの幅が第２電線３２の幅よりも大きく形成されることで、側板部３６ｂが第２電線３２の側部から離間するように設定されている。また、裏側カバー３６は、側板部３６ｂの先端から幅方向外側に延びる締結部３６ｃを有する。裏側カバー３６の締結部３６ｃは、中央カバー３４の締結部３４ａと上下方向に重なる位置に設けられている。 The back cover 36 is made of metal. The back cover 36 is an extruded material extruded in the extending direction. The back side cover 36 covers the second electric wire 32 from the back side surface side of the central cover 34. The back side cover 36 has a contact flat portion 36a as a contact portion that contacts the second electric wire 32 and sandwiches the second electric wire 32 with the central cover 34. The contact flat portion 36a is formed in a flat plate shape, and is a flat surface of the second electric wire 32. Specifically, the contact flat portion 36a is in surface contact with the flat surface on the side opposite to the side in which the central cover 34 is in surface contact. Further, the back side cover 36 has a side plate portion 36b that bends from both sides of the contact flat portion 36a and extends toward the central cover 34 side to cover the side portion of the second electric wire 32 and separate from the side portion. The back side cover 36 is set so that the side plate portion 36b is separated from the side portion of the second electric wire 32 by forming the width of the contact flat portion 36a larger than the width of the second electric wire 32. Further, the back side cover 36 has a fastening portion 36c extending outward in the width direction from the tip of the side plate portion 36b. The fastening portion 36c of the back side cover 36 is provided at a position where it overlaps the fastening portion 34a of the central cover 34 in the vertical direction.
　そして、中央カバー３４、表側カバー３５及び裏側カバー３６は、それらの締結部３４ａ，３５ｃ，３６ｃが共通の締結部材であるボルト３７及びナット３８にて締結されている。すなわち、中央カバー３４、表側カバー３５及び裏側カバー３６は、それらの締結部３４ａ，３５ｃ，３６ｃを貫通してナット３８に螺合されるボルト３７によって固定されている。また、本実施形態では、中央カバー３４、表側カバー３５及び裏側カバー３６を組み付ける際に、第１電線３１及び第２電線３２が中央カバー３４と当接平坦部３５ａ，３６ａとに圧縮されつつ挟まれるように、第１電線３１及び第２電線３２の組み付け前の寸法が設定されている。すなわち、組み付けられる前の状態の第１電線３１及び第２電線３２の高さ、詳しくは扁平面と直交する方向の長さは、組み付けられた状態の中央カバー３４と当接平坦部３５ａ，３６ａとの間隔よりも僅かに大きく設定されている。これにより、第１電線３１及び第２電線３２は、その扁平面が中央カバー３４及び当接平坦部３５ａ，３６ａと面接触するようになっている。 The central cover 34, the front cover 35, and the back cover 36 are fastened with bolts 37 and nuts 38 whose fastening portions 34a, 35c, and 36c are common fastening members. That is, the center cover 34, the front cover 35, and the back cover 36 are fixed by bolts 37 that penetrate the fastening portions 34a, 35c, and 36c and are screwed into the nut 38. Further, in the present embodiment, when the central cover 34, the front side cover 35, and the back side cover 36 are assembled, the first electric wire 31 and the second electric wire 32 are sandwiched between the central cover 34 and the contact flat portions 35a and 36a while being compressed. The dimensions of the first electric wire 31 and the second electric wire 32 before assembly are set so as to be used. That is, the heights of the first electric wire 31 and the second electric wire 32 in the state before being assembled, specifically, the length in the direction orthogonal to the flat surface, are the contact flat portions 35a and 36a with the central cover 34 in the assembled state. It is set slightly larger than the interval with. As a result, the flat surface of the first electric wire 31 and the second electric wire 32 comes into surface contact with the central cover 34 and the contact flat portions 35a and 36a.
　次に、上記のように構成されたワイヤハーネス１０の作用について説明する。 Next, the operation of the wire harness 10 configured as described above will be described.
　ワイヤハーネス１０における中央ワイヤハーネス２１は、車両Ｖの床下を通り外部に露出するため、小石等の異物が衝突する虞があるが、小石等の異物が衝突しても第１電線３１及び第２電線３２は外装部材３３に覆われているためその損傷が防止される。 Since the central wire harness 21 in the wire harness 10 passes under the floor of the vehicle V and is exposed to the outside, there is a risk of foreign matter such as pebbles colliding with each other. Since the electric wire 32 is covered with the exterior member 33, its damage is prevented.
　次に、上記実施形態の効果を以下に記載する。 Next, the effects of the above embodiment will be described below.
　（１）扁平な第１電線３１の扁平面が面接触される表側面と、扁平な第２電線３２の扁平面が面接触される裏側面とを有する金属製で平板状の中央カバー３４を備えるため、第１電線３１及び第２電線３２が共に広い範囲で金属製の中央カバー３４と接触し、第１電線３１及び第２電線３２の放熱性が良好となる。また、第１電線３１及び第２電線３２は、扁平な形状であるため、車両Ｖの高さ方向と対応した中央ワイヤハーネス２１の高さを小さくすることができる。すなわち、例えば、第１電線３１及び第２電線３２が断面円形の丸線であると、中央ワイヤハーネス２１の高さが大きく積み上がってしまい車両Ｖへの配索が困難となるが、それを回避することができる。 (1) A metal flat center cover 34 having a front side surface in which the flat surface of the flat first electric wire 31 is in surface contact and a back surface in which the flat surface of the flat second electric wire 32 is in surface contact. Therefore, both the first electric wire 31 and the second electric wire 32 come into contact with the metal central cover 34 in a wide range, and the heat dissipation of the first electric wire 31 and the second electric wire 32 becomes good. Further, since the first electric wire 31 and the second electric wire 32 have a flat shape, the height of the central wire harness 21 corresponding to the height direction of the vehicle V can be reduced. That is, for example, if the first electric wire 31 and the second electric wire 32 are round wires having a circular cross section, the height of the central wire harness 21 is greatly piled up, which makes it difficult to route to the vehicle V. It can be avoided.
　（２）表側カバー３５及び裏側カバー３６は、対応する第１電線３１または第２電線３２と当接して該第１電線３１または該第２電線３２を中央カバー３４とで挟む当接部としての当接平坦部３５ａ，３６ａを有するため、例えば、第１電線３１及び第２電線３２を中央カバー３４に面接触させて保持するための別部材が不要となる。 (2) The front side cover 35 and the back side cover 36 serve as a contact portion that abuts on the corresponding first electric wire 31 or the second electric wire 32 and sandwiches the first electric wire 31 or the second electric wire 32 with the central cover 34. Since the contact flat portions 35a and 36a are provided, for example, a separate member for holding the first electric wire 31 and the second electric wire 32 in surface contact with the central cover 34 becomes unnecessary.
　（３）当接平坦部３５ａ，３６ａは、第１電線３１の扁平面または第２電線３２の扁平面と面接触されるため、放熱性がより良好となる。 (3) Since the contact flat portions 35a and 36a are in surface contact with the flat surface of the first electric wire 31 or the flat surface of the second electric wire 32, the heat dissipation is improved.
　（４）表側カバー３５及び裏側カバー３６は、金属製であるため、放熱性がより良好となる。また、電磁シールド効果を得ることができる。 (4) Since the front side cover 35 and the back side cover 36 are made of metal, the heat dissipation is improved. Moreover, the electromagnetic shield effect can be obtained.
　（５）表側カバー３５及び裏側カバー３６は、当接平坦部３５ａ，３６ａから屈曲して中央カバー３４側に延びて第１電線３１または第２電線３２の側部を覆い且つ該側部から離間する側板部３５ｂ，３６ｂを有する。よって、第１電線３１及び第２電線３２は、中央カバー３４と当接平坦部３５ａ，３６ａとで挟まれる際に側板部３５ｂ，３６ｂ側に広がることが可能となる。 (5) The front side cover 35 and the back side cover 36 bend from the contact flat portions 35a and 36a and extend toward the central cover 34 side to cover the side portion of the first electric wire 31 or the second electric wire 32 and separate from the side portion. It has side plate portions 35b and 36b. Therefore, the first electric wire 31 and the second electric wire 32 can be extended to the side plate portions 35b and 36b when they are sandwiched between the central cover 34 and the contact flat portions 35a and 36a.
　（６）中央カバー３４、表側カバー３５及び裏側カバー３６は、共通の締結部材であるボルト３７及びナット３８にて締結される締結部３４ａ，３５ｃ，３６ｃを有するため、例えば、締結部材の数を少なくすることができる。 (6) Since the center cover 34, the front side cover 35, and the back side cover 36 have fastening portions 34a, 35c, and 36c to be fastened by the bolts 37 and nuts 38 which are common fastening members, for example, the number of fastening members may be increased. Can be reduced.
