Description

ワイヤハーネスwire harness
　本開示は、ワイヤハーネスに関するものである。 The present disclosure relates to wire harnesses.
　従来、ハイブリッド車や電気自動車等の車両に用いられるワイヤハーネスは、高電圧のバッテリとインバータなどの電気機器間を電気的に接続する電線を備えている。この種のワイヤハーネスにおいては、ノイズ低減を目的として、電線の外周が電磁シールド部材によって覆われている（例えば、特許文献１参照）。電磁シールド部材としては、編組線や金属箔などが用いられる。 Conventionally, wire harnesses used in vehicles such as hybrid vehicles and electric vehicles have wires that electrically connect high-voltage batteries and electrical devices such as inverters. In this type of wire harness, the outer periphery of the electric wire is covered with an electromagnetic shield member for the purpose of noise reduction (see, for example, Patent Document 1). A braided wire, a metal foil, or the like is used as the electromagnetic shield member.
特開２０１５－０７６８９９号公報JP 2015-076899 A
　ところで、電磁シールド部材として金属箔を用いた場合には、電磁シールド部材として編組線を用いる場合に比べて、電磁シールド部材の軽量化を図ることができる。しかし、金属箔は、編組線に比べて柔軟性及び伸張性が低い。このため、電線を大きく曲げて配索する場合には、その電線の曲げに追従できずに金属箔が破れるおそれがある。金属箔が破れると、電磁シールド機能が低下するという問題がある。 By the way, when metal foil is used as the electromagnetic shielding member, the weight of the electromagnetic shielding member can be reduced compared to the case where a braided wire is used as the electromagnetic shielding member. However, metal foils are less flexible and extensible than braided wires. For this reason, when the electric wire is routed with a large bend, there is a risk that the metal foil will break because it cannot follow the bending of the electric wire. If the metal foil is torn, there is a problem that the electromagnetic shielding function is deteriorated.
　本開示の目的は、電磁シールド機能の低下を抑制できるワイヤハーネスを提供することにある。 An object of the present disclosure is to provide a wire harness capable of suppressing deterioration of the electromagnetic shielding function.
　本開示のワイヤハーネスは、電線と、前記電線の外周を囲う電磁シールド部材と、を有するワイヤハーネスであって、前記電磁シールド部材は、前記電線の長さ方向に沿う第１方向と前記第１方向と直交する第２方向とに広がるシート状の金属層を有し、前記金属層は、前記第１方向に伸縮可能な折り曲げ部を有する。 A wire harness according to the present disclosure includes an electric wire and an electromagnetic shielding member surrounding an outer circumference of the electric wire, wherein the electromagnetic shielding member is arranged in a first direction along the length direction of the electric wire and the first It has a sheet-like metal layer that extends in a direction and a second direction perpendicular to the direction, and the metal layer has a bent portion that can expand and contract in the first direction.

　［本開示の実施形態の説明］
　最初に本開示の実施形態を列挙して説明する。
　［１］本開示のワイヤハーネスは、電線と、前記電線の外周を囲う電磁シールド部材と、を有するワイヤハーネスであって、前記電磁シールド部材は、前記電線の長さ方向に沿う第１方向と前記第１方向と直交する第２方向とに広がるシート状の金属層を有し、前記金属層は、前記第１方向に伸縮可能な折り曲げ部を有する。 [Description of Embodiments of the Present Disclosure]
First, the embodiments of the present disclosure will be enumerated and described.
[1] A wire harness according to the present disclosure is a wire harness having an electric wire and an electromagnetic shielding member surrounding the outer circumference of the electric wire, wherein the electromagnetic shielding member is arranged in a first direction along the length direction of the electric wire and It has a sheet-shaped metal layer that extends in the first direction and a second direction perpendicular to the metal layer, and the metal layer has a bent portion that can expand and contract in the first direction.
　この構成によれば、シート状の金属層に、電線の長さ方向に沿う第１方向に伸縮可能な折り曲げ部が設けられる。この折り曲げ部が第１方向に伸縮することにより、電線の曲げに金属層を好適に追従させることができ、金属層が破れることを好適に抑制できる。例えば、電線を大きく曲げて配索する場合には、電線の曲げに追従して金属層が曲がる。このとき、曲げ外側における折り曲げ部が第１方向に伸びるとともに、曲げ内側における折り曲げ部が第１方向に縮むことにより、曲げ部分における金属層の内外周差を好適に吸収できる。これにより、金属層が破れることを好適に抑制できる。このため、電磁シールド部材における電磁シールド機能が低下することを好適に抑制できる。 According to this configuration, the sheet-shaped metal layer is provided with a bent portion that can expand and contract in the first direction along the length of the electric wire. Since the bent portion expands and contracts in the first direction, the metal layer can be made to follow the bending of the electric wire, and breakage of the metal layer can be suppressed. For example, when an electric wire is routed with a large bend, the metal layer bends following the bending of the electric wire. At this time, the bent portion on the outer side of the bend extends in the first direction, and the bent portion on the inner side of the bend contracts in the first direction, so that the difference between the inner and outer circumferences of the metal layer at the bent portion can be preferably absorbed. Thereby, it can suppress suitably that a metal layer is torn. Therefore, deterioration of the electromagnetic shielding function of the electromagnetic shielding member can be suitably suppressed.
　［２］前記折り曲げ部は、前記第２方向に沿って延びる１以上の山部と前記第２方向に沿って延びる１以上の谷部とを含み、前記山部と前記谷部とは前記第１方向に交互に連なっていることが好ましい。この構成によれば、第２方向に沿って延びる山部及び谷部が第１方向に伸縮することにより、曲げ部分における金属層の内外周差を好適に吸収できる。これにより、金属層が破れることを好適に抑制できるため、電磁シールド部材における電磁シールド機能が低下することを好適に抑制できる。 [2] The bent portion includes one or more peaks extending along the second direction and one or more valleys extending along the second direction, and the peaks and valleys are It is preferable that they are alternately arranged in one direction. According to this configuration, the peaks and valleys extending along the second direction expand and contract in the first direction, so that the difference between the inner and outer circumferences of the metal layer at the bent portion can be preferably absorbed. As a result, it is possible to suitably suppress the breaking of the metal layer, so it is possible to suitably suppress the deterioration of the electromagnetic shielding function of the electromagnetic shielding member.
　［３］前記電磁シールド部材は、前記金属層を厚み方向に貫通するスリット部を有し、前記スリット部は、前記電磁シールド部材の前記第１方向において部分的に設けられることが好ましい。この構成によれば、金属層を厚み方向に貫通するスリット部が、電磁シールド部材の第１方向に部分的に設けられる。このため、第２方向に延びる山部及び谷部と交差する位置にスリット部が設けられる。これにより、例えば電線の外周を包囲するように電磁シールド部材を第２方向に巻く際に、第２方向に延びる山部及び谷部をスリット部により分断することができる。この結果、電磁シールド部材を第２方向に巻く際における電磁シールド部材の巻き付け性を好適に向上できる。 [3] It is preferable that the electromagnetic shield member has a slit portion penetrating the metal layer in the thickness direction, and the slit portion is partially provided in the first direction of the electromagnetic shield member. According to this configuration, the slit portion penetrating the metal layer in the thickness direction is partially provided in the first direction of the electromagnetic shield member. Therefore, slits are provided at positions intersecting the peaks and valleys extending in the second direction. Thereby, for example, when the electromagnetic shielding member is wound in the second direction so as to surround the outer circumference of the electric wire, the peaks and valleys extending in the second direction can be divided by the slits. As a result, the winding property of the electromagnetic shielding member can be favorably improved when winding the electromagnetic shielding member in the second direction.
　［４］前記電磁シールド部材は、前記第１方向と前記第２方向とに広がるシートであり、前記電磁シールド部材は、前記第２方向における第１端部と、前記第１端部の反対側の第２端部とを有しており、前記電磁シールド部材は、前記第１端部に前記第２端部を重ね合わせることにより、前記電線の外周を包囲する筒状をなし、前記電磁シールド部材のうち前記折り曲げ部が設けられる部分は、前記第２方向の全長にわたって前記スリット部が設けられていない第１部分を有することが好ましい。この構成によれば、シート状の電磁シールド部材の第１端部に第２端部を重ね合わせることにより、電磁シールド部材が、電線の外周を包囲する筒状をなしている。すなわち、シート状の電磁シールド部材を第２方向に巻くことにより、電磁シールド部材が筒状になる。このとき、電磁シールド部材のうち折り曲げ部が設けられる部分には、第２方向の全長にわたってスリット部が設けられていない第１部分がある。この第１部分では、スリット部が設けられていないため、第２方向における剛性を高めることができる。したがって、第２方向からの外力が第１部分に加わった場合であっても、その外力によって第１部分が変形することを抑制できる。これにより、例えば電磁シールド部材の筒状態を好適に維持することができる。 [4] The electromagnetic shield member is a sheet that extends in the first direction and the second direction, and the electromagnetic shield member has a first end in the second direction and a side opposite to the first end. The electromagnetic shield member has a tubular shape surrounding the outer periphery of the electric wire by overlapping the second end on the first end, and the electromagnetic shield It is preferable that the portion of the member where the bent portion is provided has a first portion where the slit portion is not provided over the entire length in the second direction. According to this configuration, the sheet-like electromagnetic shielding member has a tubular shape surrounding the outer circumference of the electric wire by overlapping the second end on the first end of the sheet-like electromagnetic shielding member. That is, by winding the sheet-like electromagnetic shielding member in the second direction, the electromagnetic shielding member becomes cylindrical. At this time, the portion of the electromagnetic shield member where the bent portion is provided includes the first portion where the slit portion is not provided over the entire length in the second direction. Since the first portion is not provided with a slit portion, it is possible to increase the rigidity in the second direction. Therefore, even if an external force is applied to the first portion from the second direction, deformation of the first portion due to the external force can be suppressed. Thereby, for example, the tubular state of the electromagnetic shield member can be preferably maintained.
　［５］前記谷部は、第１谷折り部と、前記第１谷折り部と前記第１方向において離れて設けられる第２谷折り部と、前記第１谷折り部と前記第２谷折り部との間に設けられる第１平面部とを有し、前記スリット部は、前記山部と交差するように延びており、前記第１平面部は、前記第１部分を有することが好ましい。この構成によれば、スリット部が山部と交差するように延びる。このため、シートである電磁シールド部材を第２方向に巻く際に、山部をスリット部により好適に分断することができ、電磁シールド部材の巻き付け性を向上できる。また、谷部は、第１谷折り部及び第２谷折り部と、それら第１谷折り部と第２谷折り部との間に設けられる第１平面部とを有する。このため、谷部とその谷部と隣接する一方の山部とが第１谷折り部により区切られ、谷部とその谷部と隣接する他方の山部とが第２谷折り部により区切られる。このように、第１谷折り部及び第２谷折り部によって谷部と山部とを区切ることができる。このとき、山部は、第１谷折り部及び第２谷折り部から筒状の電磁シールド部材の径方向外側に突出する。このため、例えば山部の第１方向に沿う寸法を調整することによって、第１谷折り部及び第２谷折り部からの山部の突出量を調整することができ、折り曲げ部における第１方向の伸縮量を調整することができる。ここで、第１谷折り部及び第２谷折り部によって谷部と山部とが区切られるため、谷部及び山部の寸法を個別に設定することができる。したがって、山部の第１方向に沿う寸法を容易に調整することができるため、折り曲げ部における第１方向の伸縮量を容易に大きくすることができる。これにより、電線の曲げに金属層を好適に追従させることができ、金属層が破れることを好適に抑制できる。さらに、谷部の第１平面部が、第２方向の全長にわたってスリット部が設けられていない第１部分を有する。このため、例えば電線の外周面に第１平面部が接触される場合に、その第１平面部と電線の外周面との接触面積が小さくなることを抑制できる。 [5] The valley portion includes a first valley fold portion, a second valley fold portion separated from the first valley fold portion in the first direction, and the first valley fold portion and the second valley fold. It is preferable that the slit extends so as to intersect with the peak, and the first planar portion has the first portion. According to this configuration, the slit portion extends so as to intersect the peak portion. Therefore, when the electromagnetic shielding member, which is a sheet, is wound in the second direction, the peaks can be suitably divided by the slits, and the winding performance of the electromagnetic shielding member can be improved. Also, the valley portion has a first valley fold portion, a second valley fold portion, and a first planar portion provided between the first valley fold portion and the second valley fold portion. Therefore, the valley and one of the peaks adjacent to the valley are separated by the first valley fold, and the valley and the other peak adjacent to the valley are separated by the second valley fold. . In this way, the valley and peak can be separated by the first valley fold and the second valley fold. At this time, the peak portions protrude radially outward of the tubular electromagnetic shield member from the first valley fold portion and the second valley fold portion. Therefore, for example, by adjusting the dimension of the peaks along the first direction, it is possible to adjust the amount of protrusion of the peaks from the first valley fold and the second valley fold. You can adjust the amount of expansion and contraction. Here, since the valley and the peak are separated by the first valley fold and the second valley fold, the dimensions of the valley and the peak can be set individually. Therefore, it is possible to easily adjust the dimension of the peak portion along the first direction, so that the amount of expansion and contraction of the bent portion in the first direction can be easily increased. As a result, the metal layer can be made to follow the bending of the electric wire, and the breakage of the metal layer can be suppressed. Furthermore, the first planar portion of the valley portion has a first portion in which the slit portion is not provided over the entire length in the second direction. Therefore, for example, when the first flat portion is in contact with the outer peripheral surface of the electric wire, it is possible to prevent the contact area between the first flat portion and the outer peripheral surface of the electric wire from becoming small.
　［６］前記山部は、第１山折り部と、前記第１山折り部と前記第１方向において離れて設けられる第２山折り部と、前記第１山折り部と前記第２山折り部との間に設けられる第２平面部と、前記谷部から前記第１山折り部に向かって前記電磁シールド部材の径方向外側に突出する第１突出部と、前記谷部から前記第２山折り部に向かって前記径方向外側に突出する第２突出部と、を有し、前記第２平面部は、前記第１突出部と交差する平面上に広がることが好ましい。この構成によれば、山部が、電磁シールド部材の径方向外側に突出する第１突出部と交差する平面上に広がる第２平面部を有する。この第２平面部が設けられるため、山部の第１方向に沿う寸法を長く設定した場合であっても、谷部から電磁シールド部材の径方向外側に突出する山部の突出量が大きくなることを抑制できる。このため、折り曲げ部における第１方向の伸縮量を大きく設定した場合であっても、筒状の電磁シールド部材の外形が大きくなることを抑制できる。 [6] The mountain portion includes a first mountain fold portion, a second mountain fold portion provided apart from the first mountain fold portion in the first direction, and the first mountain fold portion and the second mountain fold portion. a second planar portion provided between the portion, a first projecting portion projecting radially outward of the electromagnetic shield member from the valley portion toward the first mountain fold portion, and the second projecting portion from the valley portion and a second projecting portion projecting outward in the radial direction toward the mountain fold, and the second planar portion preferably spreads on a plane that intersects the first projecting portion. According to this configuration, the peak portion has the second planar portion that extends on a plane that intersects with the first projecting portion projecting radially outward of the electromagnetic shield member. Since the second plane portion is provided, even when the dimension of the peak portion along the first direction is set long, the amount of protrusion of the peak portion that protrudes radially outward of the electromagnetic shield member from the valley portion increases. can be suppressed. Therefore, even when the amount of expansion and contraction in the first direction at the bent portion is set large, it is possible to suppress the outer shape of the tubular electromagnetic shield member from becoming large.
　［７］前記電磁シールド部材は、前記第１方向と前記第２方向とに広がるシートであり、前記電磁シールド部材は、前記第２方向における第１端部と、前記第１端部の反対側の第２端部とを有しており、前記電磁シールド部材は、前記第１端部に前記第２端部を重ね合わせることにより、前記電線の外周を包囲する筒状をなし、前記電磁シールド部材のうち前記折り曲げ部が設けられる部分は、前記電磁シールド部材の前記第２方向において１つ以上の前記スリット部を有することが好ましい。この構成によれば、シート状の電磁シールド部材の第１端部に第２端部を重ね合わせることにより、電磁シールド部材が、電線の外周を包囲する筒状になる。すなわち、シート状の電磁シールド部材を第２方向に巻くことにより、電磁シールド部材が筒状になる。このとき、電磁シールド部材のうち折り曲げ部が設けられる部分では、電磁シールド部材の巻き方向である第２方向において１つ以上のスリット部が設けられる。すなわち、電磁シールド部材のうち折り曲げ部が設けられる部分では、電磁シールド部材の巻き方向に必ず１つ以上のスリット部が存在する。このため、シート状の電磁シールド部材を第２方向に巻く際に、山部及び谷部をスリット部により好適に分断することができ、電磁シールド部材の巻き付け性を好適に向上できる。 [7] The electromagnetic shielding member is a sheet extending in the first direction and the second direction, and the electromagnetic shielding member has a first end in the second direction and a side opposite to the first end. The electromagnetic shield member has a tubular shape surrounding the outer periphery of the electric wire by overlapping the second end on the first end, and the electromagnetic shield It is preferable that the portion of the member provided with the bent portion has one or more slit portions in the second direction of the electromagnetic shield member. According to this configuration, the sheet-like electromagnetic shield member is formed into a tubular shape surrounding the outer circumference of the electric wire by overlapping the second end portion with the first end portion of the sheet-shaped electromagnetic shield member. That is, by winding the sheet-like electromagnetic shielding member in the second direction, the electromagnetic shielding member becomes cylindrical. At this time, one or more slit portions are provided in the second direction, which is the winding direction of the electromagnetic shield member, in the portion of the electromagnetic shield member where the bent portion is provided. That is, in the portion of the electromagnetic shield member where the bent portion is provided, one or more slit portions are always present in the winding direction of the electromagnetic shield member. Therefore, when the sheet-shaped electromagnetic shielding member is wound in the second direction, the peaks and the valleys can be suitably divided by the slits, and the winding performance of the electromagnetic shielding member can be suitably improved.
　また、シート状の電磁シールド部材を第２方向に巻くことにより、電磁シールド部材を電線の外周を包囲する筒状にできるため、電線に対して電磁シールド部材を後から容易に取り付けることができる。これにより、ワイヤハーネスの組立作業性を向上できる。 Further, by winding the sheet-shaped electromagnetic shielding member in the second direction, the electromagnetic shielding member can be formed into a tubular shape surrounding the outer circumference of the electric wire, so that the electromagnetic shielding member can be easily attached to the electric wire later. Thereby, the workability of assembling the wire harness can be improved.
　［８］前記スリット部は、前記第１方向に沿って延びることが好ましい。この構成によれば、第２方向に延びる山部及び谷部と交差するようにスリット部が延びる。このため、例えば電線の外周を包囲するように電磁シールド部材を第２方向に巻く際に、スリット部により山部及び谷部を好適に分断することができる。この結果、電磁シールド部材を第２方向に巻く際における電磁シールド部材の巻き付け性を好適に向上できる。 [8] It is preferable that the slit portion extends along the first direction. According to this configuration, the slit extends so as to cross the peaks and valleys extending in the second direction. Therefore, for example, when the electromagnetic shielding member is wound in the second direction so as to surround the outer circumference of the electric wire, the peaks and valleys can be suitably divided by the slits. As a result, the winding property of the electromagnetic shielding member can be favorably improved when winding the electromagnetic shielding member in the second direction.
　［９］前記スリット部の前記第１方向の端部は、円弧状に湾曲していることが好ましい。この構成によれば、スリット部の第１方向の端部が円弧状に湾曲している。このため、例えば電磁シールド部材を第２方向に巻くことに伴ってスリット部の開口幅が第２方向に広がる場合に、スリット部の第１方向の端部において１か所に応力が集中することを抑制できる。これにより、スリット部が第１方向に沿って延びるように裂けることを好適に抑制できる。 [9] It is preferable that an end portion of the slit portion in the first direction is curved in an arc shape. According to this configuration, the end portion of the slit portion in the first direction is curved in an arc shape. Therefore, for example, when the opening width of the slit expands in the second direction as the electromagnetic shield member is wound in the second direction, the stress concentrates at one end of the slit in the first direction. can be suppressed. As a result, it is possible to suitably suppress the slit portion from being torn so as to extend along the first direction.
　［１０］前記電線が内部に収容されるとともに、前記電磁シールド部材と電気的に接続される金属製の筒状部材を更に有し、前記電磁シールド部材は、前記筒状部材から引き出された前記電線の外周を包囲しており、前記電磁シールド部材は、前記第１方向における第３端部と、前記第３端部の反対側の第４端部とを有しており、前記第３端部は、前記筒状部材の外周面に接続される接続部分であることが好ましい。この構成によれば、電線の外周が筒状部材に包囲されるとともに、筒状部材から引き出された電線の外周が電磁シールド部材に包囲される。また、電磁シールド部材の第３端部が筒状部材と電気的に接続される。これら筒状部材及び電磁シールド部材により、例えば電線から発生する電磁波（電磁ノイズ）の外部への放射を好適に抑制できる。 [10] The electric wire is housed inside and further has a metallic cylindrical member electrically connected to the electromagnetic shielding member, the electromagnetic shielding member being the electromagnetic shielding member drawn out from the cylindrical member. The electromagnetic shield member surrounds the outer circumference of the electric wire, and has a third end in the first direction and a fourth end opposite to the third end. The portion is preferably a connection portion connected to the outer peripheral surface of the tubular member. According to this configuration, the outer circumference of the electric wire is surrounded by the tubular member, and the outer circumference of the electric wire pulled out from the tubular member is surrounded by the electromagnetic shield member. Also, the third end of the electromagnetic shield member is electrically connected to the tubular member. The cylindrical member and the electromagnetic shielding member can suitably suppress the radiation of electromagnetic waves (electromagnetic noise) generated from electric wires, for example, to the outside.
　［１１］前記第３端部には、前記折り曲げ部が設けられてないことが好ましい。この構成によれば、筒状部材と電磁シールド部材との接続部分である第３端部に、折り曲げ部が設けられていない。このため、第３端部に折り曲げ部を設ける場合に比べて、第３端部における電磁シールド部材の巻き付け性を向上でき、筒状部材と電磁シールド部材との接続信頼性を向上できる。 [11] It is preferable that the third end is not provided with the bent portion. According to this configuration, the bent portion is not provided at the third end, which is the connecting portion between the tubular member and the electromagnetic shield member. Therefore, compared to the case where the bent portion is provided at the third end, the winding property of the electromagnetic shielding member at the third end can be improved, and the connection reliability between the tubular member and the electromagnetic shielding member can be improved.
　［１２］前記金属層は、前記電線に向く内周面と、前記内周面と反対側の外周面とを有し、前記電磁シールド部材は、前記金属層の前記外周面に積層される第１樹脂層を有し、前記第１樹脂層は、前記金属層よりも高い輻射率を有することが好ましい。この構成によれば、金属層の輻射率が低い場合であっても、その金属層の外周面が高い輻射率を有する第１樹脂層によって被覆される。このため、第１樹脂層を有さない場合に比べて、輻射による熱放射を大きくすることができる。これにより、電磁シールド部材における放熱性を向上させることができる。ひいては、ワイヤハーネスの放熱性を向上させることができる。 [12] The metal layer has an inner peripheral surface facing the electric wire and an outer peripheral surface opposite to the inner peripheral surface, and the electromagnetic shield member is a second layer laminated on the outer peripheral surface of the metal layer. It is preferable to have one resin layer, and the first resin layer has a higher emissivity than the metal layer. According to this configuration, even if the metal layer has a low emissivity, the outer peripheral surface of the metal layer is covered with the first resin layer having a high emissivity. Therefore, compared to the case where the first resin layer is not provided, thermal radiation by radiation can be increased. Thereby, heat dissipation in the electromagnetic shield member can be improved. As a result, the heat dissipation of the wire harness can be improved.
　［１３］前記電磁シールド部材は、前記金属層の前記内周面に積層される第２樹脂層を有し、前記第２樹脂層は、前記金属層よりも高い輻射率を有することが好ましい。この構成によれば、金属層の輻射率が低い場合であっても、その金属層の内周面が高い輻射率を有する第２樹脂層によって被覆される。このため、第２樹脂層を有さない場合に比べて、輻射による熱放射を大きくすることができる。これにより、電磁シールド部材における放熱性を向上させることができ、ワイヤハーネスにおける放熱性を向上させることができる。 [13] The electromagnetic shield member preferably has a second resin layer laminated on the inner peripheral surface of the metal layer, and the second resin layer preferably has a higher emissivity than the metal layer. According to this configuration, even if the metal layer has a low emissivity, the inner peripheral surface of the metal layer is covered with the second resin layer having a high emissivity. Therefore, compared to the case where the second resin layer is not provided, heat radiation by radiation can be increased. Thereby, the heat dissipation in the electromagnetic shield member can be improved, and the heat dissipation in the wire harness can be improved.
　［１４］前記第１樹脂層は、前記金属層よりも低いヤング率を有し、前記第２樹脂層は、前記金属層よりも低いヤング率を有することが好ましい。この構成によれば、金属層の内周面及び外周面に、その金属層よりもヤング率の低い第１樹脂層及び第２樹脂層がそれぞれ積層される。このため、金属層のみの単層構造に比べて、電磁シールド部材の柔軟性及び伸張性を高めることができる。これにより、例えば電線の曲げ部において、その曲げ形状に電磁シールド部材が追従しやすくなり、金属層が破れることを好適に抑制できる。 [14] Preferably, the first resin layer has a Young's modulus lower than that of the metal layer, and the second resin layer has a Young's modulus lower than that of the metal layer. According to this configuration, the first resin layer and the second resin layer having a Young's modulus lower than that of the metal layer are respectively laminated on the inner peripheral surface and the outer peripheral surface of the metal layer. For this reason, the flexibility and extensibility of the electromagnetic shield member can be improved as compared with a single layer structure of only a metal layer. As a result, for example, at the bent portion of the electric wire, the electromagnetic shield member can easily follow the bent shape, and it is possible to suitably suppress the breakage of the metal layer.
　［１５］前記第３端部における前記金属層の前記内周面は、前記第２樹脂層から露出されており、前記筒状部材の前記外周面に直接接触されることが好ましい。この構成によれば、電磁シールド部材のうち筒状部材の外周面に接続される第３端部では、第２樹脂層から露出された金属層の内周面が筒状部材の外周面に直接接触されている。このため、金属層の内周面に第２樹脂層を積層した場合であっても、金属層と筒状部材とを好適に電気的に接続することができる。 [15] It is preferable that the inner peripheral surface of the metal layer at the third end portion is exposed from the second resin layer and is in direct contact with the outer peripheral surface of the tubular member. According to this configuration, at the third end portion of the electromagnetic shield member connected to the outer peripheral surface of the tubular member, the inner peripheral surface of the metal layer exposed from the second resin layer directly contacts the outer peripheral surface of the tubular member. being contacted. Therefore, even when the second resin layer is laminated on the inner peripheral surface of the metal layer, the metal layer and the tubular member can be preferably electrically connected.
　［１６］前記金属層が前記筒状部材に接触された状態で、前記電磁シールド部材を前記筒状部材に固定する固定部材を更に有することが好ましい。この構成によれば、金属層が筒状部材に接触された状態で、電磁シールド部材が固定部材によって筒状部材に固定される。これにより、電磁シールド部材と筒状部材との電気的導通を安定的に維持することができる。 [16] It is preferable to further include a fixing member that fixes the electromagnetic shield member to the tubular member while the metal layer is in contact with the tubular member. According to this configuration, the electromagnetic shield member is fixed to the tubular member by the fixing member while the metal layer is in contact with the tubular member. Thereby, the electrical continuity between the electromagnetic shield member and the cylindrical member can be stably maintained.
　［１７］前記金属層は、前記筒状部材と同種の金属により形成されており、前記固定部材は、前記金属層及び前記筒状部材と同種の金属により形成されることが好ましい。この構成によれば、電磁シールド部材の金属層と筒状部材と固定部材とが全て同種の金属によって形成される。このため、金属層と筒状部材との接続部分、及び電磁シールド部材と固定部材との接続部分に水が付着した場合であっても、各部材間での電食の発生を抑制できる。これにより、金属層と筒状部材との間における電気的接続信頼性が低下することを抑制できる。また、金属層と筒状部材との接続部分の構造を、その接続部分を覆うゴム製の防水カバー等を設けない非防水構造とすることもできる。ここで、本明細書において、同種の金属とは、イオン化傾向が実質的に同じ金属をいう。イオン化傾向が実質的に同じとは、イオン化傾向が同一である場合は勿論、異なる場合であってもイオン化傾向が近接しているために略同じとみなせる場合も含む。 [17] Preferably, the metal layer is made of the same kind of metal as the tubular member, and the fixing member is made of the same kind of metal as the metal layer and the tubular member. According to this configuration, the metal layer of the electromagnetic shielding member, the cylindrical member, and the fixing member are all made of the same kind of metal. Therefore, even if water adheres to the connecting portion between the metal layer and the cylindrical member and the connecting portion between the electromagnetic shield member and the fixed member, it is possible to suppress the occurrence of electrolytic corrosion between the members. Thereby, it is possible to suppress the deterioration of the electrical connection reliability between the metal layer and the cylindrical member. Moreover, the structure of the connecting portion between the metal layer and the cylindrical member may be a non-waterproof structure in which a rubber waterproof cover or the like that covers the connecting portion is not provided. Here, in the present specification, the metals of the same kind refer to metals having substantially the same ionization tendency. The term "substantially the same ionization tendency" includes not only the same ionization tendency but also different ionization tendencies that can be regarded as substantially the same because the ionization tendencies are close to each other.

　ここで、金属層３５を形成する金属（例えば、アルミニウム）は、一般に熱伝導率の点では優れるものの、輻射率（放射率）の点では優れない場合が多い。例えば、アルミニウムの輻射率は０．１以下である。そこで、金属層３５の外周面に、その外周面よりも高い輻射率を有する樹脂層３６を接着するようにした。これにより、樹脂層３６を積層しない場合に比べて、輻射による熱放射を大きくすることができる。 Here, the metal (for example, aluminum) that forms the metal layer 35 is generally excellent in terms of thermal conductivity, but is often not excellent in terms of emissivity (emissivity). For example, the emissivity of aluminum is 0.1 or less. Therefore, a resin layer 36 having a higher emissivity than the outer peripheral surface is adhered to the outer peripheral surface of the metal layer 35 . As a result, compared to the case where the resin layer 36 is not laminated, heat radiation by radiation can be increased.
　このとき、ウィーンの変位則によると、物体から熱放射によって放出される光の波長のピークは、物体の温度に反比例するとされている。また、輻射率は、材料が同じでも物体の温度（光の波長）に応じて異なる値を取る材料があることが知られている。本実施形態では、ワイヤハーネス１０が車両Ｖ（図１参照）に搭載されることから、樹脂層３６としては、車両Ｖの使用環境で生じる高温度帯におけるピーク波長に対して高い輻射率を有することが好ましい。 At this time, according to Wien's displacement law, the peak wavelength of light emitted by thermal radiation from an object is said to be inversely proportional to the object's temperature. It is also known that some materials have different emissivity values depending on the temperature of the object (wavelength of light) even if the material is the same. In the present embodiment, since the wire harness 10 is mounted on the vehicle V (see FIG. 1), the resin layer 36 has a high emissivity with respect to the peak wavelength in the high temperature range that occurs in the usage environment of the vehicle V. is preferred.
　図３に示すように、電磁シールド部材３０の端部３１，３２の重なり部分では、例えば、端部３１における樹脂層３６の外周面に対して端部３２における金属層３５の内周面が接触している。これら端部３１，３２の重なり部分では、端部３１における金属層３５と端部３２における金属層３５とが電線２０の径方向に重なって配置されるため、金属層３５が二重に重なって巻かれている。 As shown in FIG. 3 , in the overlapped portion of the ends 31 and 32 of the electromagnetic shield member 30 , for example, the inner peripheral surface of the metal layer 35 at the end 32 is in contact with the outer peripheral surface of the resin layer 36 at the end 31 . is doing. In the overlapping portion of these end portions 31 and 32, the metal layer 35 at the end portion 31 and the metal layer 35 at the end portion 32 are arranged to overlap in the radial direction of the electric wire 20, so that the metal layer 35 is double overlapped. Rolled.

Specifically, in the electromagnetic shield member 30 of this embodiment, the inner peripheral surface of the metal layer 35 and the outer peripheral surface of the resin layer 36 are not provided with adhesive surfaces or adhesive surfaces. The electromagnetic shielding member 30 is maintained in a cylindrical state, for example, by winding a binding member (not shown) at the intermediate portion in the length direction of the electromagnetic shielding member 30 . As the binding member, for example, a tape member or a binding band can be used. The binding members are provided at predetermined intervals in the length direction of the electromagnetic shield member 30, for example.

　図６に示すように、電磁シールド部材３０は、シート状の電磁シールド部材３０を第２方向Ｙ１に巻くことによって筒状になる（図中太線矢印参照）。このとき、第２方向Ｙ１に延びる各山部４１は、スリット部４６と交差する部分において分断されている。本実施形態の各山部４１は、第２方向Ｙ１において複数のスリット部４６と交差する。このため、各山部４１は、その山部４１と交差するスリット部４６の数の分だけ、第２方向Ｙ１において分割されている。これにより、電磁シールド部材３０を第２方向Ｙ１に巻く際に、第２方向Ｙ１に延びる山部４１を複数のスリット部４６により分断できるため、電磁シールド部材３０の巻き付け性を向上できる。同様に、第２方向Ｙ１に延びる各谷部４２は、スリット部４７と交差する部分において分断されている。本実施形態の各谷部４２は、第２方向Ｙ１において複数のスリット部４７と交差する。このため、各谷部４２は、その谷部４２と交差するスリット部４７の数の分だけ、第２方向Ｙ１において分割されている。これにより、電磁シールド部材３０を第２方向Ｙ１に巻く際に、第２方向Ｙ１に延びる谷部４２を複数のスリット部４７により分断できるため、電磁シールド部材３０の巻き付け性を向上できる。 As shown in FIG. 6, the electromagnetic shielding member 30 is formed into a tubular shape by winding the sheet-like electromagnetic shielding member 30 in the second direction Y1 (see the thick arrow in the figure). At this time, each peak portion 41 extending in the second direction Y1 is divided at a portion crossing the slit portion 46 . Each peak portion 41 of the present embodiment intersects a plurality of slit portions 46 in the second direction Y1. Therefore, each peak portion 41 is divided in the second direction Y1 by the number of slit portions 46 intersecting the peak portion 41 . As a result, when the electromagnetic shielding member 30 is wound in the second direction Y1, the peak portions 41 extending in the second direction Y1 can be divided by the plurality of slit portions 46, so that the winding performance of the electromagnetic shielding member 30 can be improved. Similarly, each trough portion 42 extending in the second direction Y1 is divided at a portion crossing the slit portion 47 . Each trough portion 42 of the present embodiment intersects a plurality of slit portions 47 in the second direction Y1. Therefore, each valley 42 is divided in the second direction Y1 by the number of slits 47 intersecting with the valley 42 . Thereby, when winding the electromagnetic shielding member 30 in the second direction Y1, the grooves 42 extending in the second direction Y1 can be divided by the plurality of slits 47, so that the winding performance of the electromagnetic shielding member 30 can be improved.
　図３及び図６に示すように、筒状の電磁シールド部材３０では、スリット部４５の開口幅が第２方向Ｙ１に広がっている。これにより、電線２０の外周面に対応するように電線２０の周方向に沿って電磁シールド部材３０を曲げることができるため、電磁シールド部材３０の巻き付け性を向上できる。 As shown in FIGS. 3 and 6, in the tubular electromagnetic shield member 30, the opening width of the slit portion 45 is widened in the second direction Y1. Thereby, the electromagnetic shield member 30 can be bent along the circumferential direction of the electric wire 20 so as to correspond to the outer peripheral surface of the electric wire 20, so that the winding property of the electromagnetic shield member 30 can be improved.
　図４に示すように、電磁シールド部材３０の第１方向Ｘ１における端部３３，３４には、例えば、折り曲げ部４０（山部４１及び谷部４２）が設けられていない。また、端部３３，３４には、例えば、スリット部４５が設けられていない。 As shown in FIG. 4, the end portions 33 and 34 of the electromagnetic shield member 30 in the first direction X1 are not provided with, for example, the bent portions 40 (peak portions 41 and valley portions 42).

As used herein, the term "homogeneous metal" refers to metals having substantially the same ionization tendency. The term "substantially the same ionization tendency" includes not only the same ionization tendency but also different ionization tendencies that can be regarded as substantially the same because the ionization tendencies are close to each other. The range in which the ionization tendency of the first metal and the second metal can be considered to be substantially the same is a combination of metals that does not cause electrolytic corrosion when the first metal and the second metal are electrically connected by an aqueous solution containing an electrolyte.

For example, if the crimping rings 71 and 72 have a structure in which a plated film is laminated on the surface of the base material, the plated film is formed of the same kind of metal as the metal layer 35 .
　本実施形態では、金属層３５が純アルミニウム又はアルミニウム合金により形成されており、筒状部材５１，６１がアルミニウム合金により形成されており、カシメリング７１，７２がアルミニウム合金により形成されている。具体的には、金属層３５の材料としては、純アルミニウムを含む１０００系、又は８０００系のアルミニウム合金を好適に用いることができる。筒状部材５１，６１の材料としては、３０００系のアルミニウム合金やダイカスト用アルミニウム合金（ＡＤＣ材）を用いることができる。ＡＤＣ材としては、アルミニウム合金ＡＤＣ３やアルミニウム合金ＡＤＣ１２などを挙げることができる。筒状部材５１，６１の材料としては、金属層３５が純アルミニウム又はアルミニウム合金からなる場合には、電食防止の観点から、銅の添加量の少ない３０００系のアルミニウム合金を用いることが好適である。また、筒状部材５１，６１としては、鉄合金からなる母材に対して溶融アルミニウムメッキを施すことにより、母材の表面にアルミニウムメッキ被膜を積層した構造体を用いることもできる。なお、鉄合金としては、例えば、炭素鋼、特殊鋼やステンレス鋼を用いることができる。本実施形態のカシメリング７１，７２としては、鉄合金からなる母材に対して溶融アルミニウムメッキを施すことにより、母材の表面にアルミニウムメッキ被膜を積層した構造体を有している。 In this embodiment, the metal layer 35 is made of pure aluminum or an aluminum alloy, the cylindrical members 51 and 61 are made of an aluminum alloy, and the crimping rings 71 and 72 are made of an aluminum alloy.

　（外装部材８０の構成）
　図３に示すように、外装部材８０は、例えば、電磁シールド部材３０の外周を包囲するように設けられている。外装部材８０は、例えば、電磁シールド部材３０の外周を周方向全周にわたって包囲する。外装部材８０は、例えば、全体として長尺の筒状をなしている。外装部材８０の内部には、電磁シールド部材３０及び電磁シールド部材３０により被覆された複数の電線２０が収容されている。外装部材８０は、内部に収容した電線２０及び電磁シールド部材３０を飛翔物や水滴から保護する。なお、図２では、外装部材８０の図示を省略している。 (Structure of exterior member 80)
As shown in FIG. 3, the exterior member 80 is provided so as to surround the outer periphery of the electromagnetic shield member 30, for example. The exterior member 80 surrounds, for example, the entire circumference of the electromagnetic shield member 30 in the circumferential direction. The exterior member 80 has, for example, a long tubular shape as a whole. An electromagnetic shielding member 30 and a plurality of electric wires 20 covered by the electromagnetic shielding member 30 are accommodated inside the exterior member 80 . The exterior member 80 protects the electric wire 20 and the electromagnetic shield member 30 accommodated inside from flying objects and water droplets. 2, illustration of the exterior member 80 is omitted.
　外装部材８０としては、例えば、金属製や樹脂製のパイプ、コルゲートチューブやゴム製の防水カバー又はこれらを組み合わせて用いることができる。金属製のパイプやコルゲートチューブの材料としては、例えば、アルミニウム系や銅系などの金属材料を用いることができる。樹脂製のパイプやコルゲートチューブの材料としては、例えば、導電性を有する樹脂材料や導電性を有さない樹脂材料を用いることができる。樹脂材料としては、例えば、ポリオレフィン、ポリアミド、ポリエステル、ＡＢＳ樹脂などの合成樹脂を用いることができる。 As the exterior member 80, for example, a metal or resin pipe, a corrugated tube, a rubber waterproof cover, or a combination thereof can be used.

As the resin material, for example, synthetic resin such as polyolefin, polyamide, polyester, and ABS resin can be used.
　次に、本実施形態の作用効果を説明する。
　（１－１）電磁シールド部材３０の有するシート状の金属層３５に、電線２０の長さ方向に沿う第１方向Ｘ１に伸縮可能な折り曲げ部４０を設けるようにした。この折り曲げ部４０が第１方向Ｘ１に伸縮することにより、電線２０の曲げに金属層３５を好適に追従させることができ、金属層３５が破れることを好適に抑制できる。例えば、電線２０を大きく曲げて配索する場合には、電線２０の曲げに追従して金属層３５が曲がる。このとき、曲げ外側における折り曲げ部４０が第１方向Ｘ１に伸びるとともに、曲げ内側における折り曲げ部４０が第１方向Ｘ１に縮むように変形する。本実施形態では、曲げ外側における山部４１及び谷部４２が第１方向Ｘ１に延びるとともに、曲げ内側における山部４１及び谷部４２が第１方向Ｘ１に縮むように変形する。これにより、曲げ部分における金属層３５の内外周差を好適に吸収できるため、電線２０の曲げに起因して金属層３５が破れることを好適に抑制できる。このため、電磁シールド部材３０における電磁シールド機能が低下することを好適に抑制できる。 Next, the effects of this embodiment will be described.
(1-1) The sheet-shaped metal layer 35 of the electromagnetic shield member 30 is provided with the bent portion 40 that can be stretched in the first direction X1 along the length direction of the electric wire 20 . The bending portion 40 expands and contracts in the first direction X1, so that the metal layer 35 can be appropriately made to follow the bending of the electric wire 20, and the breakage of the metal layer 35 can be preferably suppressed. For example, when the wire 20 is routed with a large bend, the metal layer 35 bends following the bending of the wire 20 . At this time, the bent portion 40 on the outside of the bend extends in the first direction X1, and the bent portion 40 on the inside of the bend contracts in the first direction X1. In this embodiment, the peaks 41 and valleys 42 on the outside of the bend extend in the first direction X1, and the peaks 41 and the valleys 42 on the inside of the bend deform so as to contract in the first direction X1. As a result, since the difference between the inner and outer circumferences of the metal layer 35 at the bent portion can be favorably absorbed, the breakage of the metal layer 35 due to the bending of the electric wire 20 can be favorably suppressed. Therefore, deterioration of the electromagnetic shielding function of the electromagnetic shielding member 30 can be suitably suppressed.
　（１－２）金属層３５を貫通するスリット部４５を、電磁シールド部材３０の第１方向Ｘ１に部分的に設けるようにした。また、スリット部４５は、第１方向Ｘ１に沿って延びる。このため、山部４１及び谷部４２と交差するようにスリット部４５が延びる。これにより、電線２０の外周を包囲するように電磁シールド部材３０を第２方向Ｙ１に巻く際に、第２方向Ｙ１に延びる山部４１及び谷部４２をスリット部４５により分断することができる。この結果、電磁シールド部材３０を第２方向Ｙ１に巻く際における電磁シールド部材３０の巻き付け性を好適に向上できる。 (1-2) The slit portion 45 penetrating the metal layer 35 is partially provided in the first direction X1 of the electromagnetic shield member 30 . Also, the slit portion 45 extends along the first direction X1. Therefore, the slit portion 45 extends so as to intersect the peak portion 41 and the valley portion 42 . Thereby, when the electromagnetic shielding member 30 is wound in the second direction Y1 so as to surround the outer circumference of the electric wire 20, the peaks 41 and the valleys 42 extending in the second direction Y1 can be divided by the slits 45. As a result, the winding property of the electromagnetic shielding member 30 when winding the electromagnetic shielding member 30 in the second direction Y1 can be preferably improved.
　（１－３）シート状の電磁シールド部材３０の端部３１に端部３２を重ね合わせることにより、電磁シールド部材３０は、電線２０の外周を包囲する筒状になる。すなわち、シート状の電磁シールド部材３０を第２方向Ｙ１に巻くことにより、電磁シールド部材３０を筒状にした。さらに、電磁シールド部材３０のうち折り曲げ部４０が設けられる部分では、電磁シールド部材３０の巻き方向である第２方向Ｙ１において１つ以上のスリット部４５を設けるようにした。すなわち、電磁シールド部材３０のうち折り曲げ部４０が設けられる部分では、電磁シールド部材３０の巻き方向に必ず１つ以上のスリット部４５が存在する。このため、シート状の電磁シールド部材３０を第２方向Ｙ１に巻く際に、山部４１及び谷部４２をスリット部４５により好適に分断することができ、電磁シールド部材３０の巻き付け性を好適に向上できる。 (1-3) By overlapping the end portion 32 of the sheet-like electromagnetic shield member 30 with the end portion 31, the electromagnetic shield member 30 becomes a cylinder surrounding the outer circumference of the electric wire 20. That is, the sheet-like electromagnetic shielding member 30 is wound in the second direction Y1 to form the electromagnetic shielding member 30 into a tubular shape. Furthermore, in the portion of the electromagnetic shield member 30 where the bent portion 40 is provided, one or more slit portions 45 are provided in the second direction Y1, which is the winding direction of the electromagnetic shield member 30 . That is, in the portion of the electromagnetic shield member 30 where the bent portion 40 is provided, one or more slit portions 45 always exist in the winding direction of the electromagnetic shield member 30 . Therefore, when the sheet-like electromagnetic shielding member 30 is wound in the second direction Y1, the peaks 41 and the valleys 42 can be suitably divided by the slits 45, and the winding properties of the electromagnetic shielding member 30 can be suitably improved. can improve.
　（１－４）シート状の電磁シールド部材３０を第２方向Ｙ１に巻くことにより、電磁シールド部材３０を電線２０の外周を包囲する筒状にできるため、電線２０に対して電磁シールド部材３０を後から容易に取り付けることができる。これにより、ワイヤハーネス１０の組立作業性を向上できる。 (1-4) By winding the sheet-shaped electromagnetic shielding member 30 in the second direction Y1, the electromagnetic shielding member 30 can be formed into a cylindrical shape surrounding the outer circumference of the electric wire 20. It can be easily installed later. Thereby, the assembly workability of the wire harness 10 can be improved.
　（１－５）さらに、端部３１と端部３２との重なり幅を調整することにより、電線２０の外周寸法に合わせて電磁シールド部材３０の内周寸法及び外周寸法を容易に調整することができる。これにより、電磁シールド部材３０の外周寸法が大型化することを好適に抑制できる。 (1-5) Furthermore, by adjusting the width of overlap between the end portion 31 and the end portion 32, it is possible to easily adjust the inner and outer peripheral dimensions of the electromagnetic shield member 30 according to the outer peripheral dimension of the electric wire 20. can. Thereby, it can control suitably that the outer peripheral dimension of the electromagnetic shielding member 30 enlarges.
　（１－６）筒状部材５１と電磁シールド部材３０との接続部分である端部３３に、折り曲げ部４０を設けないようにした。また、筒状部材６１と電磁シールド部材３０との接続部分である端部３４に、折り曲げ部４０を設けないようにした。このため、端部３３，３４に折り曲げ部４０を設ける場合に比べて、端部３３，３４における電磁シールド部材３０の巻き付け性を向上でき、筒状部材５１，６１と電磁シールド部材３０との接続信頼性を向上できる。 (1-6) The bent portion 40 is not provided at the end portion 33 that is the connecting portion between the tubular member 51 and the electromagnetic shield member 30 . Also, the bent portion 40 is not provided at the end portion 34 which is the connecting portion between the tubular member 61 and the electromagnetic shield member 30 . Therefore, compared to the case where the bent portions 40 are provided at the ends 33, 34, the winding property of the electromagnetic shield member 30 at the ends 33, 34 can be improved, and the connection between the tubular members 51, 61 and the electromagnetic shield member 30 can be improved. Reliability can be improved.
　（１－７）金属層３５の外周面に、金属層３５よりも高い輻射率を有する樹脂層３６を積層するようにした。この構成によれば、金属層３５の輻射率が低い場合であっても、その金属層３５の外周面が高い輻射率を有する樹脂層３６によって被覆される。このため、樹脂層３６を有さない場合に比べて、輻射による熱放射を大きくすることができる。したがって、例えば電磁シールド部材３０の外周面と外装部材８０の内周面とが物理的に離れていても、電磁シールド部材３０の外周面から輻射によって外装部材８０に効率的に熱伝導させることができる。これにより、電磁シールド部材３０における放熱性を向上させることができ、ワイヤハーネス１０の放熱性を向上させることができる。 (1-7) A resin layer 36 having a higher emissivity than the metal layer 35 is laminated on the outer peripheral surface of the metal layer 35 . According to this configuration, even if the emissivity of the metal layer 35 is low, the outer peripheral surface of the metal layer 35 is covered with the resin layer 36 having a high emissivity. Therefore, compared to the case where the resin layer 36 is not provided, heat radiation by radiation can be increased. Therefore, for example, even if the outer peripheral surface of the electromagnetic shield member 30 and the inner peripheral surface of the exterior member 80 are physically separated, heat can be efficiently conducted to the exterior member 80 by radiation from the outer peripheral surface of the electromagnetic shield member 30. can. Thereby, the heat dissipation in the electromagnetic shield member 30 can be improved, and the heat dissipation of the wire harness 10 can be improved.
　（１－８）金属層３５の外周面に、金属層３５よりもヤング率の低い樹脂層３６を積層するようにした。この構成によれば、金属層３５のみの単層構造に比べて、電磁シールド部材３０の柔軟性及び伸張性を高めることができる。これにより、例えば電線２０の曲げ部において、その曲げ形状に電磁シールド部材３０が追従しやすくなり、金属層３５が破れることを抑制できる。 (1-8) A resin layer 36 having a Young's modulus lower than that of the metal layer 35 is laminated on the outer peripheral surface of the metal layer 35 . According to this configuration, the flexibility and extensibility of the electromagnetic shield member 30 can be enhanced as compared with a single layer structure of only the metal layer 35 . As a result, for example, at the bent portion of the electric wire 20 , the electromagnetic shield member 30 can easily follow the bent shape, and the breakage of the metal layer 35 can be suppressed.
　（１－９）金属層３５の内周面及び外周面のうち外周面のみに樹脂層３６を積層するようにした。すなわち、金属層３５の内周面に樹脂層を積層しないようにした。このため、電磁シールド部材３０の第１方向Ｘ１の端部３３，３４を筒状部材５１，６１に固定する際に、金属層３５の内周面を筒状部材５１，６１の外周面に直接接触させることができる。これにより、電磁シールド部材３０の端部３３，３４、つまり筒状部材５１，６１との接続部分において、樹脂層を剥ぐ等の工程を行わずに、電磁シールド部材３０と筒状部材５１，６１とを好適に電気的に接続することができる。 (1-9) The resin layer 36 is laminated only on the outer peripheral surface of the inner peripheral surface and the outer peripheral surface of the metal layer 35 . That is, the resin layer was not laminated on the inner peripheral surface of the metal layer 35 . Therefore, when fixing the ends 33 and 34 of the electromagnetic shield member 30 in the first direction X1 to the tubular members 51 and 61, the inner peripheral surface of the metal layer 35 is directly attached to the outer peripheral surface of the tubular members 51 and 61. can be contacted. As a result, the electromagnetic shield member 30 and the tubular members 51 and 61 can be separated from each other without performing a process such as peeling off the resin layer at the ends 33 and 34 of the electromagnetic shield member 30, that is, the connection portions with the tubular members 51 and 61. can be preferably electrically connected to each other.
　（１－１０）樹脂層３６の材料として導電性を有する樹脂材料を用いた場合には、仮に電線２０の曲げ部において金属層３５が破れてしまった場合であっても、樹脂層３６によって電磁シールド機能を維持することができる。 (1-10) When a conductive resin material is used as the material of the resin layer 36, even if the metal layer 35 is torn at the bent portion of the wire 20, the resin layer 36 Shield function can be maintained.
　（１－１１）金属層３５が筒状部材５１，６１に接触した状態で、電磁シールド部材３０を筒状部材５１，６１にそれぞれ固定するカシメリング７１，７２を設けた。この構成によれば、電磁シールド部材３０がカシメリング７１，７２によって外側から筒状部材５１，６１に向かって締め付けられる。これにより、金属層３５の内周面が筒状部材５１，６１の外周面に接触した状態で電磁シールド部材３０が筒状部材５１，６１に固定される。したがって、電磁シールド部材３０と筒状部材５１，６１との電気的導通を安定的に維持することができる。 (1-11) Crimping rings 71 and 72 are provided for fixing the electromagnetic shield member 30 to the tubular members 51 and 61, respectively, while the metal layer 35 is in contact with the tubular members 51 and 61, respectively. According to this configuration, the electromagnetic shield member 30 is tightened from the outside toward the cylindrical members 51 and 61 by the crimping rings 71 and 72 . As a result, the electromagnetic shield member 30 is fixed to the tubular members 51 and 61 while the inner peripheral surface of the metal layer 35 is in contact with the outer peripheral surfaces of the tubular members 51 and 61 . Therefore, electrical continuity between the electromagnetic shield member 30 and the tubular members 51 and 61 can be stably maintained.
　（１－１２）電磁シールド部材３０の金属層３５と筒状部材５１，６１とカシメリング７１，７２とを全て同種の金属により形成するようにした。このため、金属層３５と筒状部材５１，６１との接続部分、及び電磁シールド部材３０とカシメリング７１，７２との接続部分に水が付着した場合であっても、各部材間での電食の発生を抑制できる。これにより、電食に起因して電磁シールド部材３０の電磁シールド性能が低下することを抑制できる。また、金属層３５と筒状部材５１，６１との接続部分の構造を、その接続部分を覆うゴム製の防水カバー等を設けない非防水構造とすることもできる。換言すると、非防水構造とした場合であっても、金属層３５及び筒状部材５１，６１に電食が発生することを抑制できる。この結果、ワイヤハーネス１０の大型化を抑制でき、部品点数の増加を抑制できる。 (1-12) The metal layer 35 of the electromagnetic shield member 30, the cylindrical members 51 and 61, and the caulking rings 71 and 72 are all made of the same kind of metal. Therefore, even if water adheres to the connecting portions between the metal layer 35 and the cylindrical members 51 and 61 and the connecting portions between the electromagnetic shield member 30 and the crimping rings 71 and 72, the electric current between the members will be reduced. It can suppress the occurrence of eclipse. Thereby, it can suppress that the electromagnetic shield performance of the electromagnetic shield member 30 falls due to electrolytic corrosion. Moreover, the structure of the connecting portion between the metal layer 35 and the tubular members 51 and 61 may be a non-waterproof structure in which a rubber waterproof cover or the like that covers the connecting portion is not provided. In other words, it is possible to suppress the occurrence of electrolytic corrosion in the metal layer 35 and the tubular members 51 and 61 even in the case of a non-waterproof structure. As a result, an increase in size of the wire harness 10 can be suppressed, and an increase in the number of parts can be suppressed.

The electromagnetic shield member 30A extends in a first direction X1 and a second direction Y1 orthogonal to the first direction X1, and has a predetermined thickness in a third direction Z1 orthogonal to both the first direction X1 and the second direction Y1. is a sheet. The electromagnetic shield member 30A has, for example, ends 31 and 32 in the second direction Y1 and ends 33 and 34 in the first direction X1.
　図９に示すように、電磁シールド部材３０Ａは、シート状の電磁シールド部材３０Ａを第２方向Ｙ１に巻くことによって筒状になる。図示は省略するが、電磁シールド部材３０Ａは、図８に示した端部３１と端部３２とを電線２０の径方向に重ね合わせることによって筒状になる。 As shown in FIG. 9, the electromagnetic shielding member 30A is formed into a tubular shape by winding the sheet-like electromagnetic shielding member 30A in the second direction Y1.

You can adjust the amount of expansion and contraction.

Extends to portion 92B.
　各スリット部９５は、例えば、谷部９２に設けられていない。各スリット部９５は、例えば、谷部９２の平面部９２Ｃに設けられていない。換言すると、平面部９２Ｃには、谷部９２が延びる第２方向Ｙ１の全長にわたってスリット部９５が設けられていない。すなわち、平面部９２Ｃは、第２方向Ｙ１の全長にわたってスリット部９５が設けられていない第１部分を有している。この第１部分は、例えば、平面部９２Ｃの第１方向Ｘ１の中間部に設けられている。第１部分は、例えば、平面部９２Ｃの第１方向Ｘ１の全長にわたって設けられている。ここで、本明細書において「Ａ部はＢ部に設けられていない」とは、Ａ部が完全にＢ部に設けられていない場合の他、製造公差や組み付け公差等の範囲内においてＡ部がＢ部に多少設けられる場合も含む。例えば、各スリット部９５は、谷部９２の一部まで延びていてもよい。例えば、各スリット部９５は、谷折り部９２Ａ，９２Ｂと交差していてもよい。但し、各スリット部９５は、各谷部９２の平面部９２Ｃの大部分とは交差しない。 Each slit portion 95 is not provided in the valley portion 92, for example. Each slit portion 95 is not provided on the plane portion 92C of the valley portion 92, for example. In other words, the flat portion 92C is not provided with the slit portion 95 over the entire length in the second direction Y1 in which the valley portion 92 extends. That is, the planar portion 92C has a first portion where the slit portion 95 is not provided over the entire length in the second direction Y1. This first portion is provided, for example, at an intermediate portion of the plane portion 92C in the first direction X1. The first portion is provided, for example, over the entire length of the flat portion 92C in the first direction X1. Here, in this specification, "A part is not provided in B part" means that in addition to the case where A part is not completely provided in B part, A part is provided in part B to some extent. For example, each slit portion 95 may extend to part of the valley portion 92 . For example, each slit portion 95 may cross the valley fold portions 92A and 92B. However, each slit portion 95 does not intersect most of the planar portion 92C of each valley portion 92 .
　電磁シールド部材３０Ａには、例えば、１つの山部９１に対して１つ以上のスリット部９５が設けられている。電磁シールド部材３０Ａには、１つの山部９１に対して複数（図８では、１１個）のスリット群９５Ａのスリット部９５が設けられている。１つの山部９１に対して設けられた複数（図８では、１１個）のスリット部９５は、例えば、第２方向Ｙ１において並んでいる。１つの山部９１に対して設けられた複数のスリット部９５は、第２方向Ｙ１において同じ位置にある。 The electromagnetic shield member 30A is provided with, for example, one or more slit portions 95 for one mountain portion 91. The electromagnetic shield member 30A is provided with a plurality of (11 in FIG. 8) slit portions 95A of a slit group 95A for one mountain portion 91. As shown in FIG. A plurality of (11 in FIG. 8) slit portions 95 provided for one mountain portion 91 are arranged in the second direction Y1, for example. A plurality of slit portions 95 provided for one peak portion 91 are located at the same position in the second direction Y1.
　図９に示すように、電磁シールド部材３０Ａは、シート状の電磁シールド部材３０Ａを第２方向Ｙ１に巻くことによって筒状になる。このとき、第２方向Ｙ１に延びる各山部９１は、スリット部９５と交差する部分において分断されている。本実施形態の各山部９１は、第２方向Ｙ１において複数のスリット部９５と交差する。このため、各山部９１は、その山部９１と交差するスリット部９５の数の分だけ、第２方向Ｙ１において分割されている。これにより、電磁シールド部材３０Ａを第２方向Ｙ１に巻く際に、第２方向Ｙ１に延びる山部９１を複数のスリット部９５により分断できるため、電磁シールド部材３０Ａの巻き付け性を向上できる。 As shown in FIG. 9, the electromagnetic shielding member 30A is formed into a tubular shape by winding the sheet-like electromagnetic shielding member 30A in the second direction Y1. At this time, each peak portion 91 extending in the second direction Y1 is divided at a portion crossing the slit portion 95 . Each peak portion 91 of the present embodiment intersects a plurality of slit portions 95 in the second direction Y1. Therefore, each peak portion 91 is divided in the second direction Y1 by the number of slit portions 95 intersecting the peak portion 91 . As a result, when the electromagnetic shielding member 30A is wound in the second direction Y1, the peak portions 91 extending in the second direction Y1 can be divided by the plurality of slit portions 95, so that the winding performance of the electromagnetic shielding member 30A can be improved.
　筒状の電磁シールド部材３０Ａでは、スリット部９５の開口幅が第２方向Ｙ１に広がっている。これにより、電線２０の外周面に対応するように電線２０の周方向に沿って電磁シールド部材３０Ａを曲げることができるため、電磁シールド部材３０Ａの巻き付け性を向上できる。 In the cylindrical electromagnetic shield member 30A, the opening width of the slit portion 95 is widened in the second direction Y1. Thereby, the electromagnetic shield member 30A can be bent along the circumferential direction of the electric wire 20 so as to correspond to the outer peripheral surface of the electric wire 20, so that the winding property of the electromagnetic shield member 30A can be improved.
　図８に示すように、電磁シールド部材３０Ａの第１方向Ｘ１における端部３３，３４には、例えば、折り曲げ部９０（山部９１及び谷部９２）が設けられていない。また、端部３３，３４には、例えば、スリット部９５が設けられていない。 As shown in FIG. 8, the ends 33 and 34 of the electromagnetic shield member 30A in the first direction X1 are not provided with, for example, the bent portions 90 (peak portions 91 and valley portions 92). Also, the end portions 33 and 34 are not provided with the slit portion 95, for example.
　以上説明した実施形態によれば、第１実施形態の（１－４）～（１－１２）の作用効果に加えて以下の作用効果を奏することができる。
　（２－１）電磁シールド部材３０Ａの有するシート状の金属層３５に、電線２０の長さ方向に沿う第１方向Ｘ１に伸縮可能な折り曲げ部９０を設けるようにした。この折り曲げ部９０が第１方向Ｘ１に伸縮することにより、電線２０の曲げに金属層３５を好適に追従させることができ、金属層３５が破れることを好適に抑制できる。このため、電磁シールド部材３０Ａにおける電磁シールド機能が低下することを好適に抑制できる。 According to the embodiment described above, the following effects can be obtained in addition to the effects (1-4) to (1-12) of the first embodiment.
(2-1) The sheet-like metal layer 35 of the electromagnetic shielding member 30A is provided with a bent portion 90 that can expand and contract in the first direction X1 along the length direction of the electric wire 20. FIG. The bending portion 90 expands and contracts in the first direction X1, so that the metal layer 35 can be appropriately made to follow the bending of the electric wire 20, and the breakage of the metal layer 35 can be preferably suppressed. Therefore, deterioration of the electromagnetic shielding function of the electromagnetic shielding member 30A can be suitably suppressed.
　（２－２）シート状の電磁シールド部材３０Ａの端部３１に端部３２を重ね合わせることにより、電磁シールド部材３０Ａを、電線２０の外周を包囲する筒状にした。すなわち、シート状の電磁シールド部材３０Ａを第２方向Ｙ１に巻くことにより、電磁シールド部材３０Ａを筒状にした。さらに、電磁シールド部材３０Ａのうち折り曲げ部９０が設けられる部分に、電磁シールド部材３０Ａの巻き方向である第２方向Ｙ１の全長にわたってスリット部９５が設けられていない第１部分（ここでは、谷部９２の平面部９２Ｃ）を設けるようにした。この第１部分では、第２方向Ｙ１の全長にわたってスリット部９５が設けられていないため、第２方向Ｙ１における剛性を高めることができる。したがって、第２方向Ｙ１からの外力が第１部分に加わった場合であっても、その外力によって第１部分が変形することを抑制できる。これにより、例えば電磁シールド部材３０Ａの筒状態を好適に維持することができる。 (2-2) The sheet-like electromagnetic shield member 30A is formed into a cylindrical shape surrounding the outer periphery of the electric wire 20 by overlapping the end portion 32 on the end portion 31 of the sheet-shaped electromagnetic shield member 30A. That is, the sheet-like electromagnetic shielding member 30A was wound in the second direction Y1 to form the electromagnetic shielding member 30A into a tubular shape. Furthermore, the first portion (here, valley portion A flat portion 92C) of 92 is provided. In this first portion, the slit portion 95 is not provided over the entire length in the second direction Y1, so the rigidity in the second direction Y1 can be increased. Therefore, even if an external force from the second direction Y1 is applied to the first portion, it is possible to suppress deformation of the first portion due to the external force. Thereby, for example, the cylindrical state of the electromagnetic shield member 30A can be preferably maintained.
　（２－３）金属層３５を貫通するスリット部９５を、電磁シールド部材３０Ａの第１方向Ｘ１に部分的に設けるようにした。また、スリット部９５は、山部９１と交差するように延びる。このため、電線２０の外周を包囲するように電磁シールド部材３０Ａを第２方向Ｙ１に巻く際に、第２方向Ｙ１に延びる山部９１をスリット部９５により分断することができる。この結果、電磁シールド部材３０Ａを第２方向Ｙ１に巻く際における電磁シールド部材３０Ａの巻き付け性を好適に向上できる。 (2-3) The slit portion 95 passing through the metal layer 35 is partially provided in the first direction X1 of the electromagnetic shield member 30A. Moreover, the slit portion 95 extends so as to cross the peak portion 91 . Therefore, when the electromagnetic shielding member 30A is wound in the second direction Y1 so as to surround the outer circumference of the electric wire 20, the peak portion 91 extending in the second direction Y1 can be divided by the slit portion 95. As a result, the winding property of the electromagnetic shielding member 30A can be preferably improved when winding the electromagnetic shielding member 30A in the second direction Y1.
　（２－４）谷部９２を、谷折り部９２Ａ及び谷折り部９２Ｂと、それら谷折り部９２Ａと谷折り部９２Ｂとの間に設けられる平面部９２Ｃとを有する構造にした。このため、谷部９２とその谷部９２と隣接する一方の山部９１とが谷折り部９２Ａにより区切られ、谷部９２とその谷部９２と隣接する他方の山部９１とが谷折り部９２Ｂにより区切られる。このように、谷折り部９２Ａ，９２Ｂによって谷部９２と山部９１とを区切ることができる。このとき、山部９１は、谷折り部９２Ａ，９２Ｂから筒状の電磁シールド部材３０Ａの径方向外側に突出する。このため、例えば山部９１の第１方向Ｘ１に沿う寸法を調整することによって、谷折り部９２Ａ，９２Ｂからの山部９１の突出量を調整することができ、折り曲げ部９０における第１方向Ｘ１の伸縮量を調整することができる。ここで、谷折り部９２Ａ，９２Ｂによって谷部９２と山部９１とが区切られるため、谷部９２及び山部９１の寸法を個別に設定することができる。したがって、山部９１の第１方向Ｘ１に沿う寸法を容易に調整することができるため、折り曲げ部９０における第１方向Ｘ１の伸縮量を容易に大きくすることができる。これにより、電線２０の曲げに金属層３５を好適に追従させることができ、金属層３５が破れることを好適に抑制できる。 (2-4) The valley portion 92 is configured to have a valley fold portion 92A, a valley fold portion 92B, and a plane portion 92C provided between the valley fold portions 92A and 92B. Therefore, the valley portion 92 and one of the peak portions 91 adjacent to the valley portion 92 are separated by the valley fold portion 92A, and the valley portion 92 and the other peak portion 91 adjacent to the valley portion 92 are separated by the valley fold portion. 92B. Thus, the valley portion 92 and the peak portion 91 can be separated by the valley fold portions 92A and 92B. At this time, the peak portions 91 protrude outward in the radial direction of the cylindrical electromagnetic shield member 30A from the valley fold portions 92A and 92B. Therefore, for example, by adjusting the dimension of the peak portion 91 along the first direction X1, it is possible to adjust the amount of protrusion of the peak portion 91 from the valley fold portions 92A and 92B. You can adjust the amount of expansion and contraction. Here, since the valley portion 92 and the peak portion 91 are separated by the valley fold portions 92A and 92B, the dimensions of the valley portion 92 and the peak portion 91 can be set individually. Therefore, since the dimension of the peak portion 91 along the first direction X1 can be easily adjusted, the amount of expansion and contraction of the bent portion 90 in the first direction X1 can be easily increased. Thereby, the metal layer 35 can be made to follow the bending of the electric wire 20 suitably, and the breakage of the metal layer 35 can be suitably suppressed.
　（２－５）谷部９２の底部である平面部９２Ｃに、第２方向Ｙ１の全長にわたってスリット部９５が設けられていない第１部分を設けるようにした。このため、例えば電線２０の外周面に平面部９２Ｃの内周面が接触される場合に、その平面部９２Ｃの内周面と電線２０の外周面との接触面積が小さくなることを抑制できる。 (2-5) The flat portion 92C, which is the bottom portion of the valley portion 92, is provided with a first portion in which the slit portion 95 is not provided over the entire length in the second direction Y1. Therefore, for example, when the inner peripheral surface of the flat portion 92C contacts the outer peripheral surface of the electric wire 20, the contact area between the inner peripheral surface of the flat portion 92C and the outer peripheral surface of the electric wire 20 can be suppressed from being reduced.
　（２－６）山部９１を、電磁シールド部材３０Ａの径方向外側に突出する突出部９１Ｄと交差する平面上に広がる平面部９１Ｃを有する構造にした。この平面部９１Ｃが設けられるため、山部９１の第１方向Ｘ１に沿う寸法を長く設定した場合であっても、谷部９２から電磁シールド部材３０Ａの径方向外側に突出する山部９１の突出量が大きくなることを抑制できる。このため、折り曲げ部９０における第１方向Ｘ１の伸縮量を大きく設定した場合であっても、筒状の電磁シールド部材３０Ａの外形が大きくなることを抑制できる。 (2-6) The peak portion 91 is configured to have a planar portion 91C that extends on a plane that intersects with a protruding portion 91D that protrudes radially outward from the electromagnetic shield member 30A. Since the plane portion 91C is provided, even if the dimension of the peak portion 91 along the first direction X1 is set long, the protrusion of the peak portion 91 that protrudes radially outward from the electromagnetic shield member 30A from the valley portion 92 It is possible to prevent the amount from increasing. Therefore, even when the amount of expansion and contraction in the first direction X1 of the bent portion 90 is set large, it is possible to suppress the outer shape of the cylindrical electromagnetic shield member 30A from becoming large.

Alternatively, for example, the bent portions 40 and 90 may not be provided at the ends 31 and 32 .
　・上記各実施形態では、電磁シールド部材３０，３０Ａの端部３１，３２にスリット部４５，９５を設けるようにした。これに限らず、例えば、端部３１，３２にスリット部４５，９５を設けないようにしてもよい。 · In the above-described embodiments, the slit portions 45 and 95 are provided at the ends 31 and 32 of the electromagnetic shield members 30 and 30A. Alternatively, for example, the end portions 31 and 32 may not be provided with the slit portions 45 and 95 .
　・上記各実施形態におけるスリット部４５，９５の形状は特に限定されない。例えば、スリット部４５，９５の第１方向Ｘ１の端部を、円弧状に湾曲した形状にしてもよい。例えば、電磁シールド部材３０，３０Ａの第３方向Ｚ１、つまり金属層３５の厚み方向から見た平面視において、スリット部４５，９５の第１方向Ｘ１の端部を、円弧状に湾曲した形状にしてもよい。 · The shape of the slit portions 45 and 95 in each of the above embodiments is not particularly limited. For example, the end portions of the slit portions 45 and 95 in the first direction X1 may be curved in an arc shape. For example, in a plan view of the electromagnetic shield members 30 and 30A in the third direction Z1, that is, in the thickness direction of the metal layer 35, the ends of the slit portions 45 and 95 in the first direction X1 are curved in an arc shape. may
　・例えば図１１に示す第２変更例のように、スリット部４６，４７（スリット部４５）の第１方向Ｘ１の端部に終端部４８を設けるようにしてもよい。本変更例のスリット部４６，４７は、第１方向Ｘ１に沿って延びるスリット４９と、スリット４９の第１方向Ｘ１の両端部に設けられた終端部４８とを有している。終端部４８は、例えば、スリット４９から第２方向Ｙ１に広がっている。すなわち、終端部４８の第２方向Ｙ１に沿う寸法は、スリット４９の第２方向Ｙ１に沿う寸法よりも大きい。金属層３５の厚み方向（ここでは、第３方向Ｚ１）から見た終端部４８の平面形状は、円形である。この場合の終端部４８の内側面は、曲面である。 · For example, as in a second modified example shown in FIG. 11, the end portions 48 may be provided at the ends of the slit portions 46 and 47 (the slit portion 45) in the first direction X1. The slit portions 46 and 47 of this modified example have a slit 49 extending along the first direction X1 and end portions 48 provided at both ends of the slit 49 in the first direction X1. For example, the terminal end 48 extends from the slit 49 in the second direction Y1. That is, the dimension of the terminal portion 48 along the second direction Y1 is larger than the dimension of the slit 49 along the second direction Y1. The planar shape of the end portion 48 viewed from the thickness direction of the metal layer 35 (here, the third direction Z1) is circular. The inner surface of the terminal end 48 in this case is a curved surface.
　この構成によれば、スリット部４６，４７の第１方向Ｘ１の端部、つまり終端部４８が円弧状に湾曲している。このため、例えば電磁シールド部材３０を第２方向Ｙ１に巻くことに伴ってスリット部４６，４７の開口幅が第２方向Ｙ１に広がる場合に、スリット部４６，４７の第１方向Ｘ１の端部において１か所に応力が集中することを抑制できる。換言すると、スリット部４６，４７の終端部４８において応力を分散させることができる。これにより、スリット部４６，４７が第１方向Ｘ１に沿って延びるように裂けることを好適に抑制できる。 According to this configuration, the end portions of the slit portions 46 and 47 in the first direction X1, that is, the end portions 48 are curved in an arc shape. For this reason, for example, when the opening width of the slit portions 46 and 47 widens in the second direction Y1 as the electromagnetic shield member 30 is wound in the second direction Y1, the end portions of the slit portions 46 and 47 in the first direction X1 It is possible to suppress the stress from concentrating at one place. In other words, stress can be dispersed at the end portions 48 of the slit portions 46 and 47 . As a result, it is possible to preferably prevent the slit portions 46 and 47 from tearing along the first direction X1.
　なお、スリット部４５と同様に、スリット部９５の第１方向Ｘ１の端部に終端部４８を設けるようにしてもよい。
　・例えば図１２に示す第３変更例のように、スリット部４６，４７（スリット部４５）を、長孔にしてもよい。本変更例のスリット部４６，４７は、電磁シールド部材３０の第２方向Ｙ１よりも第１方向Ｘ１に長い長孔である。すなわち、本変更例のスリット部４６，４７は、第１方向Ｘ１に沿って延びている。本変更例のスリット部４６，４７は、金属層３５の厚み方向（ここでは、第３方向Ｚ１）から見た平面形状が長円形である。ここで、本明細書における「長円形」は、２つの略等しい長さの平行線と２つの半円形からなる形状である。この構成によれば、スリット部４６，４７の第１方向Ｘ１の端部が円弧状に湾曲している。このため、スリット部４６，４７が第１方向Ｘ１に沿って延びるように裂けることを好適に抑制できる。 As with the slit portion 45, the end portion 48 may be provided at the end portion of the slit portion 95 in the first direction X1.
- For example, as in a third modification shown in FIG. 12, the slit portions 46 and 47 (slit portion 45) may be long holes. The slit portions 46 and 47 of this modified example are long holes that are longer in the first direction X1 than the second direction Y1 of the electromagnetic shield member 30 . That is, the slit portions 46 and 47 of this modified example extend along the first direction X1. The slit portions 46 and 47 of this modified example have an oval planar shape when viewed from the thickness direction of the metal layer 35 (here, the third direction Z1). Here, an "oval" in this specification is a shape consisting of two parallel lines of approximately equal length and two semi-circles. According to this configuration, the end portions of the slit portions 46 and 47 in the first direction X1 are curved in an arc shape. Therefore, it is possible to suitably suppress the slit portions 46 and 47 from being torn so as to extend along the first direction X1.
　なお、スリット部４５と同様に、スリット部９５を長孔にしてもよい。
　・図１２に示したスリット部４６，４７（スリット部４５）を、金属層３５の厚み方向から見た平面形状が楕円形になるようにしてもよい。なお、スリット部４５と同様に、スリット部９５を、金属層３５の厚み方向から見た平面形状が楕円形になるようにしてもよい。 It should be noted that the slit portion 95 may be an elongated hole, similar to the slit portion 45 .
- The slit portions 46 and 47 (slit portion 45) shown in FIG. As with the slit portion 45 , the slit portion 95 may have an elliptical planar shape when viewed from the thickness direction of the metal layer 35 .
　・例えば図１３に示す第４変更例のように、スリット部４６，４７（スリット部４５）を、丸孔にしてもよい。本変更例のスリット部４６，４７は、金属層３５の厚み方向（ここでは、第３方向Ｚ１）から見た平面形状が円形である。この構成によれば、スリット部４６，４７の第１方向Ｘ１の端部が円弧状に湾曲している。このため、スリット部４６，４７が第１方向Ｘ１に沿って延びるように裂けることを好適に抑制できる。 · For example, as in a fourth modified example shown in FIG. 13, the slit portions 46 and 47 (slit portion 45) may be round holes. The slit portions 46 and 47 of this modification have a circular planar shape when viewed from the thickness direction of the metal layer 35 (here, the third direction Z1). According to this configuration, the end portions of the slit portions 46 and 47 in the first direction X1 are curved in an arc shape. Therefore, it is possible to suitably suppress the slit portions 46 and 47 from being torn so as to extend along the first direction X1.
　なお、スリット部４５と同様に、スリット部９５を丸孔にしてもよい。
　・上記各実施形態では、電磁シールド部材３０，３０Ａに設けた複数のスリット部４５，９５を全て同一の形状にしたが、これに限定されない。例えば、図１１に示したスリット４９及び終端部４８を有するスリット部４５と、図１２に示した長孔であるスリット部４５と、図１３に示した丸孔であるスリット部４５とが１つの電磁シールド部材３０に混在していてもよい。なお、スリット部９５もスリット部４５と同様に変更することができる。 It should be noted that the slit portion 95 may be a round hole, similar to the slit portion 45 .
- In each above-mentioned embodiment, although all the some slit parts 45 and 95 provided in the electromagnetic shielding members 30 and 30A were made into the same shape, it is not limited to this. For example, the slit portion 45 having the slit 49 and the end portion 48 shown in FIG. 11, the elongated slit portion 45 shown in FIG. 12, and the round slit portion 45 shown in FIG. It may be mixed in the electromagnetic shield member 30 . Note that the slit portion 95 can also be changed in the same manner as the slit portion 45 .
　・上記各実施形態では、スリット部４５（スリット部４６，４７）及びスリット部９５を、金属層３５と接着層３７と樹脂層３６とを厚み方向に貫通するようにしたが、これに限定されない。例えば、樹脂層３６が伸縮性に優れている場合には、スリット部４５，９５を、金属層３５と接着層３７とを厚み方向に貫通するようにしてもよい。また、例えば、樹脂層３６及び接着層３７が伸縮性に優れている場合には、スリット部４５，９５を、金属層３５のみを厚み方向に貫通するようにしてもよい。 - In each of the above-described embodiments, the slit portion 45 (slit portions 46 and 47) and the slit portion 95 penetrate the metal layer 35, the adhesive layer 37, and the resin layer 36 in the thickness direction, but the present invention is not limited to this. . For example, if the resin layer 36 has excellent stretchability, the slit portions 45 and 95 may penetrate the metal layer 35 and the adhesive layer 37 in the thickness direction. Further, for example, when the resin layer 36 and the adhesive layer 37 are excellent in stretchability, the slit portions 45 and 95 may penetrate only the metal layer 35 in the thickness direction.
　・上記第１実施形態のスリット部４６を、複数の山部４１と交差するようにしてもよい。

- You may make it cross|intersect the several valley part 42 with the slit part 47 of the said 1st Embodiment.
　・上記第２実施形態のスリット部９５を、山部９１に代えて、谷部９２と交差するようにしてもよい。
　・上記第２実施形態における山部９１の構造は特に限定されない。例えば、山部９１を、山折り部９１Ｂを省略し、１つの山折り部９１Ａを有する構造に変更してもよい。この場合には、平面部９１Ｃが省略される。また、山部９１を、山折り部９１Ａ，９１Ｂの両方を有さない構造に変更してもよい。この場合の山部９１は、例えば、谷部９２から電磁シールド部材３０Ａの径方向外側に突出するとともに、円弧状に湾曲している。 - The slit portion 95 of the second embodiment may intersect the valley portion 92 instead of the peak portion 91 .
- The structure of the peak part 91 in the said 2nd Embodiment is not specifically limited. For example, the mountain portion 91 may be modified to have a structure in which the mountain fold portion 91B is omitted and one mountain fold portion 91A is provided. In this case, the plane portion 91C is omitted. Also, the peak portion 91 may be changed to a structure that does not have both the peak fold portions 91A and 91B. The peak portion 91 in this case, for example, protrudes radially outward of the electromagnetic shield member 30A from the valley portion 92 and is curved in an arc shape.
　・上記各実施形態では、複数の電線２０の外周を一括して包囲するように電磁シールド部材３０，３０Ａを筒状にしたが、これに限定されない。
　例えば図１４に示す第５変更例のように、１本の電線２０の外周を周方向全周にわたって包囲するように電磁シールド部材３０を筒状にしてもよい。なお、電磁シールド部材３０Ａも電磁シールド部材３０と同様に変更することができる。 - Although electromagnetic shielding member 30, 30A was made into the cylindrical shape so that the outer periphery of the some electric wire 20 might be enclosed collectively in said each embodiment, it is not limited to this.
For example, as in a fifth modification shown in FIG. 14, the electromagnetic shielding member 30 may be formed in a cylindrical shape so as to surround the entire outer periphery of one electric wire 20 in the circumferential direction. Note that the electromagnetic shield member 30A can also be changed in the same manner as the electromagnetic shield member 30. FIG.
　・上記各実施形態の電磁シールド部材３０，３０Ａでは、金属層３５の内周面及び外周面のうち外周面のみに樹脂層３６を積層するようにしたが、これに限定されない。
　例えば図１５に示す第６変更例のように、金属層３５の外周面に樹脂層３６を積層し、金属層３５の内周面に樹脂層３８を積層するようにしてもよい。本変更例の電磁シールド部材３０Ｂでは、金属層３５の内周面に接着層３９を介して樹脂層３８が接着されている。すなわち、電磁シールド部材３０Ｂは、電磁シールド部材３０Ｂの内周面側から樹脂層３８と接着層３９と金属層３５と接着層３７と樹脂層３６とが順に積層された積層構造を有している。電磁シールド部材３０Ｂは、例えば、樹脂層３８が電線２０に向くように配置されている。 - In the electromagnetic shielding members 30 and 30A of each of the embodiments described above, the resin layer 36 is laminated only on the outer peripheral surface of the inner peripheral surface and the outer peripheral surface of the metal layer 35, but the present invention is not limited to this.
For example, as in a sixth modification shown in FIG. 15, a resin layer 36 may be laminated on the outer peripheral surface of the metal layer 35 and a resin layer 38 may be laminated on the inner peripheral surface of the metal layer 35 . In the electromagnetic shield member 30</b>B of this modified example, a resin layer 38 is adhered to the inner peripheral surface of the metal layer 35 via an adhesive layer 39 . That is, the electromagnetic shield member 30B has a laminated structure in which a resin layer 38, an adhesive layer 39, a metal layer 35, an adhesive layer 37, and a resin layer 36 are laminated in order from the inner peripheral surface side of the electromagnetic shield member 30B. . The electromagnetic shield member 30</b>B is arranged, for example, so that the resin layer 38 faces the electric wire 20 .
　接着層３９は、金属層３５の内周面と接着されるとともに、樹脂層３８の外周面と接着されている。接着層３９は、金属層３５の内周面を覆っている。接着層３９としては、例えば、エポキシ樹脂系、ポリウレタン系、アクリル樹脂系の接着剤を用いることができる。 The adhesive layer 39 is adhered to the inner peripheral surface of the metal layer 35 and is adhered to the outer peripheral surface of the resin layer 38 . The adhesive layer 39 covers the inner peripheral surface of the metal layer 35 . As the adhesive layer 39, for example, an epoxy resin-based, polyurethane-based, or acrylic resin-based adhesive can be used.
　樹脂層３８は、樹脂層３６と同様に、シートである。樹脂層３８は、接着層３９の外周面を覆っている。樹脂層３８は、例えば、接着層３９の外周面全面を覆っている。樹脂層３８の材料としては、例えば、金属層３５よりも輻射率の高い樹脂材料を用いることができる。樹脂層３８の輻射率は、例えば、０．７以上に設定することができる。また、樹脂層３８の材料としては、例えば、金属層３５よりもヤング率の低い樹脂材料を用いることができる。樹脂層３８の材料としては、例えば、導電性を有する樹脂材料や導電性を有さない樹脂材料を用いることができる。樹脂層３８の材料としては、例えば、ポリプロピレン、ポリエチレンテレフタレートやポリエチレンなどの合成樹脂を用いることができる。 The resin layer 38 is a sheet like the resin layer 36. The resin layer 38 covers the outer peripheral surface of the adhesive layer 39 . The resin layer 38 covers, for example, the entire outer peripheral surface of the adhesive layer 39 . As a material of the resin layer 38, for example, a resin material having a higher emissivity than that of the metal layer 35 can be used. The emissivity of the resin layer 38 can be set to, for example, 0.7 or higher. As the material of the resin layer 38, for example, a resin material having a Young's modulus lower than that of the metal layer 35 can be used. As the material of the resin layer 38, for example, a conductive resin material or a non-conductive resin material can be used. As a material of the resin layer 38, for example, synthetic resin such as polypropylene, polyethylene terephthalate, and polyethylene can be used.
　電磁シールド部材３０Ｂの第１方向Ｘ１の端部３３は、筒状部材５１の外周面に接続されている。すなわち、電磁シールド部材３０Ｂの端部３３は、筒状部材５１と接続される接続部分である。電磁シールド部材３０Ｂの端部３３では、金属層３５の内周面が樹脂層３８から露出されており、金属層３５の内周面が筒状部材５１の外周面に直接接触している。換言すると、電磁シールド部材３０Ｂの端部３３では、金属層３５の内周面に接着層３９及び樹脂層３８が積層されていない。このため、電磁シールド部材３０Ｂの端部３３では、金属層３５の内周面を筒状部材５１の外周面に直接接触させることができる。これにより、金属層３５の内周面に樹脂層３８を積層した場合であっても、金属層３５と筒状部材５１とを好適に電気的に接続することができる。 The end 33 of the electromagnetic shield member 30B in the first direction X1 is connected to the outer peripheral surface of the cylindrical member 51. That is, the end portion 33 of the electromagnetic shield member 30B is a connection portion that is connected to the tubular member 51 . At the end portion 33 of the electromagnetic shield member 30B, the inner peripheral surface of the metal layer 35 is exposed from the resin layer 38, and the inner peripheral surface of the metal layer 35 is in direct contact with the outer peripheral surface of the cylindrical member 51. In other words, the adhesive layer 39 and the resin layer 38 are not laminated on the inner peripheral surface of the metal layer 35 at the end portion 33 of the electromagnetic shield member 30B. Therefore, the inner peripheral surface of the metal layer 35 can be brought into direct contact with the outer peripheral surface of the cylindrical member 51 at the end portion 33 of the electromagnetic shield member 30B. Accordingly, even when the resin layer 38 is laminated on the inner peripheral surface of the metal layer 35, the metal layer 35 and the cylindrical member 51 can be electrically connected appropriately.
　上記構成によれば、金属層３５の輻射率が低い場合であっても、その金属層３５の内周面が高い輻射率を有する樹脂層３８によって被覆される。このため、樹脂層３８を有さない場合に比べて、輻射による熱放射を大きくすることができる。したがって、例えば電磁シールド部材３０Ｂの内周面、ここでは樹脂層３８の内周面と電線２０の外周面とが物理的に離れていても、電線２０の外周面から輻射によって電磁シールド部材３０Ｂに効率的に熱伝導させることができる。さらに、金属層３５の外周面が高い輻射率を有する樹脂層３６によって被覆されるため、電磁シールド部材３０Ｂの外周面から輻射によって外装部材８０（図３参照）に効率的に熱伝導させることができる。これにより、ワイヤハーネス１０における放熱性を向上させることができる。この結果、電線２０の温度上昇を低く抑えることができるため、電線２０の芯線２１のサイズを小さくしたり、絶縁被覆２２の厚みを薄くしたりすることができる。 According to the above configuration, even if the metal layer 35 has a low emissivity, the inner peripheral surface of the metal layer 35 is covered with the resin layer 38 having a high emissivity. Therefore, compared to the case where the resin layer 38 is not provided, heat radiation by radiation can be increased. Therefore, for example, even if the inner peripheral surface of the electromagnetic shield member 30B, here the inner peripheral surface of the resin layer 38 and the outer peripheral surface of the wire 20 are physically separated, the radiation from the outer peripheral surface of the wire 20 causes the electromagnetic shield member 30B to It can conduct heat efficiently. Furthermore, since the outer peripheral surface of the metal layer 35 is covered with the resin layer 36 having a high emissivity, heat can be efficiently conducted to the exterior member 80 (see FIG. 3) by radiation from the outer peripheral surface of the electromagnetic shield member 30B. can. Thereby, heat dissipation in the wire harness 10 can be improved. As a result, the temperature rise of the electric wire 20 can be kept low, so the size of the core wire 21 of the electric wire 20 can be reduced, and the thickness of the insulating coating 22 can be reduced.
　また、金属層３５の内周面に、金属層３５よりもヤング率の低い樹脂層３８を積層したため、樹脂層３８を有さない場合に比べて、電磁シールド部材３０Ｂの柔軟性及び伸張性を高めることができる。これにより、例えば電線２０の曲げ部において、その曲げ形状に電磁シールド部材３０Ｂが追従しやすくなり、金属層３５が破れることをより抑制できる。 In addition, since the resin layer 38 having a lower Young's modulus than the metal layer 35 is laminated on the inner peripheral surface of the metal layer 35, the flexibility and extensibility of the electromagnetic shield member 30B are improved compared to the case where the resin layer 38 is not provided. can be enhanced. This makes it easier for the electromagnetic shielding member 30B to follow the bending shape of the electric wire 20, for example, and further suppresses the metal layer 35 from breaking.
