According to the same configuration, since at least one of the first route restricting member and the second route restricting member has a protruding portion protruding from the first main body portion or the second main body portion, the first route regulating member and the second route regulating member are regulated. The bending rigidity of at least one of the members can be increased. Therefore, the deviation from the path of the electric wire member can be further suppressed.
- the protrusions include a first protrusion that protrudes from the first main body toward the second main body, and a second protrusion that protrudes from the second main body toward the first main body.

Further, in the portion where the air layer is formed between the exterior member 30 and the second path restricting member 50, it becomes difficult for heat to be transferred to the inside. Therefore, for example, when the electric wire is arranged near the heat source of the vehicle V, the electric wire is used. It is possible to further suppress the temperature rise of the member 20.

That is, if the direction of the second insertion port 52 and the direction of the first insertion port 42 match, the bending rigidity of the wire harness 10 may be reduced intensively in the direction of the direction. Can be avoided. In other words, by adjusting the direction of the first insertion port 42 and the direction of the second insertion port 52, it is possible to adjust the direction in which the bending rigidity of the wire harness 10 increases or decreases in a desired direction.

Abstract
Description
最初に本開示の実施態様を列記して説明する。
本開示のワイヤハーネスは、
[1]電線部材と、前記電線部材の外周を覆う筒状の外装部材と、前記外装部材の外周側に取り付けられる第1経路規制部材と、前記第1経路規制部材の外周側に取り付けられる第2経路規制部材と、を備え、前記第1経路規制部材は、前記外装部材の外周の一部を覆う第1本体部と、前記第1本体部における周方向の両端部によって形成され、前記第1経路規制部材の長さ方向に沿うとともに当該長さ方向の全体にわたって延びており、前記外装部材が挿入可能に構成された第1挿入口と、を有し、前記第2経路規制部材は、前記第1経路規制部材の外周の一部を覆う第2本体部と、前記第2本体部における周方向の両端部によって形成され、前記第2経路規制部材の長さ方向に沿うとともに当該長さ方向の全体にわたって延びており、前記第1経路規制部材が挿入可能に構成された第2挿入口と、を有する。
同構成によれば、第2経路規制部材は、金属製であるため、当該部分では、例えば、車両の熱源に近い位置に配置された場合等に、電線部材の温度が上昇することをより抑制できる。
同構成によれば、第1経路規制部材は、樹脂製であるため、外装部材が金属製の部材と擦れて摩耗することを抑制できる。すなわち、第1経路規制部材が金属製であると、外装部材が、金属製の第1経路規制部材と擦れて摩耗し易くなる虞があるが、これを回避できる。
同構成によれば、第2経路規制部材は、樹脂製であり、有色であるため、例えば、色に応じてワイヤハーネスの種類等を作業者が認識可能となる。よって、例えば、電線部材が高圧電線を含む場合等、該電線部材を作業者が誤って切断しないように注意を促すことができる。また、第2経路規制部材は、樹脂製であるため、塗装工程等を用いずに、例えば、樹脂材に塗料を混ぜて成形することで容易に製造することができる。すなわち、第2経路規制部材を金属製とすると、成形後に塗装工程等が必要となるが、これを回避して容易に製造することができる。また、例えば、成形後に塗装してなる第2経路規制部材とした場合では、摩耗すると色を視認できなくなるが、これを回避でき、耐久性を高くすることが可能となる。
同構成によれば、第2経路規制部材は、第1経路規制部材よりも短いため、例えば、第2経路規制部材が配される部位で局所的にワイヤハーネスの曲げ剛性を高くすることができる。よって、例えば、特に必要な部位のみ局所的にワイヤハーネスの曲げ剛性をより高くしつつ、ワイヤハーネス全体は軽量化することができる。
同構成によれば、第1経路規制部材は、第2経路規制部材よりも短いため、例えば、第1経路規制部材が配される部位で局所的にワイヤハーネスの曲げ剛性を高くすることができる。よって、例えば、特に必要な部位のみ局所的にワイヤハーネスの曲げ剛性をより高くしつつ、ワイヤハーネス全体は軽量化することができる。また、外装部材と第2経路規制部材との間が空気層となる部位では、内側に熱が伝わり難くなるため、例えば、車両の熱源に近い位置に配置された場合等に、電線部材の温度が上昇することをより抑制できる。
同構成によれば、第1経路規制部材及び第2経路規制部材の少なくとも一方は、第1本体部または第2本体部から突出する突出部を有するため、第1経路規制部材及び第2経路規制部材の少なくとも一方の曲げ剛性を高くすることができる。よって、電線部材の経路からの逸脱をより抑えることができる。
同構成によれば、第2経路規制部材は、第2挿入口の向きが第1挿入口の向きと異なるように第1経路規制部材に取り付けられるため、ワイヤハーネスの曲げ剛性が低くなる方向が一方向に集中しない。すなわち、第2挿入口の向きと第1挿入口の向きとが一致していると、その向きの方向に集中的にワイヤハーネスの曲げ剛性が低くなってしまう虞があるが、それを回避することができる。言い換えると、第1挿入口の向きと第2挿入口の向きとを調整することで、ワイヤハーネスの曲げ剛性が高くなる方向や低くなる方向を所望の方向に調整することができる。
同構成によれば、例えば、保持用突出部が第1本体部における周方向の両端部から僅かに離れた位置の内面から突出している場合に比べて、第1挿入口を通じた外装部材からの第1経路規制部材の脱離をより抑制できる。

詳しくは、第1突出部43は、第1本体部41の周方向に複数設けられている。本実施形態の第1突出部43は、第1本体部41における周方向の中心よりも一方側と他方側とにそれぞれ2つずつ設けられている。また、本実施形態の第1経路規制部材40は、第1溝部45を有する。第1溝部45は、第1突出部43と対応した位置において、第1本体部41の内周から凹設され、第1経路規制部材40の長さ方向に沿って延びている。すなわち、第1突出部43は、第1本体部41の厚さをほぼ一定に保った状態で第1本体部41の外側に張り出すように形成されており、第1溝部45は、第1突出部43が張り出した分と対応して凹設されている。
図2及び図4に示すように、第2経路規制部材50は、第1経路規制部材40の外周のうち第1経路規制部材40の周方向の半分より大きい範囲を覆うとともに第1経路規制部材40の長さ方向に沿って延びている。
詳しくは、第2突出部53は、第2本体部51の周方向に複数設けられている。本実施形態の第2突出部53は、第2本体部51における周方向の中心よりも一方側と他方側とにそれぞれ2つずつ設けられている。また、第2突出部53は、第2本体部51の周方向の両端部54に設けられている。また、第2突出部53は、第2本体部51における周方向の中心に設けられている。また、本実施形態の第2経路規制部材50は、第2溝部55を有する。第2溝部55は、第2突出部53と対応した位置において、第2本体部51の外周から凹設され、第2経路規制部材50の長さ方向に沿って延びている。すなわち、第2突出部53は、第2本体部51の厚さをほぼ一定に保った状態で第2本体部51の内側に張り出すように形成されており、第2溝部55は、第2突出部53が張り出した分と対応して凹設されている。
第1経路規制部材40を長さ方向に直交する方向から第2挿入口52に挿入する際、第2経路規制部材50は弾性変形されて第2挿入口52の開口幅は大きくされる。第1経路規制部材40が第2経路規制部材50の内部に挿入されると、第2経路規制部材50が元の形状に戻ろうと弾性復帰する。これにより、第2挿入口52の開口幅が第1経路規制部材40の外径よりも小さくなるため、第1経路規制部材40に対して第2経路規制部材50が取り付けられる。
本実施形態のワイヤハーネス10によれば、外装部材30の外周に対して第1挿入口42を通じて第1経路規制部材40を後付けすることができる。言い換えると、外装部材30に対して第1経路規制部材40を、外装部材30の長さ方向と直交する方向から組み付けることができる。また、第1経路規制部材40の外周に対して第2挿入口52を通じて第2経路規制部材50を後付けすることができる。言い換えると、第1経路規制部材40に対して第2経路規制部材50を、第1経路規制部材40の長さ方向と直交する方向から組み付けることができる。
(1)外装部材30の外周に対して第1挿入口42を通じて第1経路規制部材40を後付けすることができる。また、第1経路規制部材40の外周に対して第2挿入口52を通じて第2経路規制部材50を後付けすることができる。そして、外装部材30の外周側に第1経路規制部材40と第2経路規制部材50とが二重で取り付けられるため、例えば、当該部分でのワイヤハーネス10の曲げ剛性を高くすることができる。よって、電線部材20の経路からの逸脱を抑えることができる。また、外装部材30の外周側に第1経路規制部材40と第2経路規制部材50とが二重で取り付けられるため、例えば、当該部分では、車両Vの熱源に近い位置に配置された場合等に、電線部材20の温度が上昇してしまうことを抑制できる。これらのことから、本実施形態のワイヤハーネス10では、電線部材20の保護機能を高くすることができる。
本実施形態は、以下のように変更して実施することができる。本実施形態及び以下の変更例は、技術的に矛盾しない範囲で互いに組み合わせて実施することができる。
