Abstract

The purpose of the present invention is to easily manufacture a protective member which firmly regulates routing of a wire harness body while minimizing the noise generated by contact between the protective member and the wire harness body. This wire harness is equipped with a wire harness body, which includes at least one electric wire, and a protective member. The protective member is formed by hot pressing a laminated body, which is formed from an inner-circumference-side nonwoven member and outer-circumference-side nonwoven member that are superimposed one over the other, into a form covering at least a portion of the wire harness body. The surface section on the inner circumference side of the protective member is softer than the surface section on the outer circumference side.

　また、特許文献２のように、不織布をホットプレスした保護部材によって、ワイヤーハーネスを保護する場合、保護部材が経路規制機能を発揮するためには、保護部材はなるべく硬く形成されることが好ましい。しかしながら、保護部材を硬く形成してしまうと、保護部材とワイヤーハーネスとの接触により音が発生し易い。 In addition, as in Patent Document 2, when a wire harness is protected by a protective member obtained by hot pressing a nonwoven fabric, it is preferable that the protective member is formed as hard as possible in order for the protective member to exhibit a path regulation function. However, if the protective member is formed hard, sound is likely to be generated due to contact between the protective member and the wire harness.
　そこで、本発明は、ワイヤーハーネス本体をしっかりと経路規制しつつ、保護部材とワイヤーハーネス本体との接触による異音を抑制することが可能な保護部材を容易に製造できるようにすることを目的とする。 Then, this invention aims at enabling easy manufacture of the protection member which can suppress the noise by contact with a protection member and a wire harness main body, carrying out the path | route control of a wire harness main body firmly. To do.
　上記課題を解決するため、第１の態様に係るワイヤーハーネスは、少なくとも１本の電線を含むワイヤーハーネス本体と、内周側不織部材と外周側不織部材とが重ね合された積層体が前記ワイヤーハーネス本体の少なくとも一部を覆う形状にホットプレスされることにより形成され、外周側表面部分よりも内周側表面部分が柔らかい保護部材とを備える。 In order to solve the above-described problem, the wire harness according to the first aspect includes a laminate in which a wire harness body including at least one electric wire, an inner circumferential non-woven member, and an outer circumferential non-woven member are overlapped. It is formed by hot pressing into a shape covering at least a part of the wire harness body, and includes a protective member whose inner peripheral surface portion is softer than the outer peripheral surface portion.
　第２の態様は、第１の態様に係るワイヤーハーネスであって、前記内周側不織部材と前記外周側不織部材とは、それぞれ基本繊維とバインダとを含む不織部材によって構成され、前記内周側不織部材と前記外周側不織部材とは、前記バインダの割合及び前記バインダの融点の少なくとも１つが異なる。 A 2nd aspect is a wire harness which concerns on a 1st aspect, Comprising: The said inner peripheral side non-woven member and the said outer peripheral side non-woven member are each comprised by the non-woven member containing a basic fiber and a binder, The inner peripheral side non-woven member and the outer peripheral side non-woven member differ in at least one of the ratio of the binder and the melting point of the binder.
　第３の態様は、第１又は第２の態様に係るワイヤーハーネスであって、前記ワイヤーハーネス本体の少なくとも一部が前記保護部材の内周側表面部分に対して遊びがある状態で収容されている。 A 3rd aspect is a wire harness which concerns on a 1st or 2nd aspect, Comprising: At least one part of the said wire harness main body is accommodated in the state with play with respect to the inner peripheral side surface part of the said protection member. Yes.
　第４の態様は、第１～第３のいずれか１つの態様に係るワイヤーハーネスであって、前記ワイヤーハーネス本体の少なくとも一部が前記保護部材の内周側表面部分によって挟まれている。 A fourth aspect is a wire harness according to any one of the first to third aspects, wherein at least a part of the wire harness body is sandwiched between inner peripheral surface portions of the protective member.
　第５の態様は、第１～第４のいずれか１つの態様に係るワイヤーハーネスであって、前記保護部材は、それぞれ前記ワイヤーハーネス本体の少なくとも一部を配設可能な凹部を有する複数の分割保護体の組合わせによって構成され、前記分割保護体のそれぞれが、前記内周側不織部材と前記外周側不織部材とが重ね合された前記積層体がその両面側から挟込まれてホットプレスされることにより形成されている。 A fifth aspect is a wire harness according to any one of the first to fourth aspects, wherein the protection member has a plurality of divisions each having a recess in which at least a part of the wire harness body can be disposed. Each of the divided protective bodies is formed by a combination of protective bodies, and the laminated body in which the inner peripheral side non-woven member and the outer peripheral side non-woven member are overlapped is sandwiched from both sides of the hot body. It is formed by pressing.
　第６の態様は、第５の態様に係るワイヤーハーネスであって、前記複数の分割保護体は、ヒンジによって開閉可能に連結されている。 The sixth aspect is a wire harness according to the fifth aspect, wherein the plurality of divided protective bodies are connected by a hinge so as to be opened and closed.
　第７の態様は、第５の態様に係るワイヤーハーネスであって、前記複数の分割保護体は、それぞれ別体に形成されている。 The seventh aspect is a wire harness according to the fifth aspect, wherein the plurality of divided protective bodies are formed separately.
　第８の態様に係るワイヤーハーネスの製造方法は、(a)複数の不織部材を重ね合せる工程と、(b)前記複数の不織部材を重ね合せた積層体をその両面側から挟込んでホットプレスすることによりワイヤーハーネス本体の少なくとも一部を配設可能な凹部を含み、外周側表面部分よりも内周側表面部分が柔らかい分割保護体を複数製造する工程と、(c)前記複数の分割保護体内に前記ワイヤーハーネス本体の少なくとも一部を収容するように、前記複数の分割保護体を合体させる工程とを備える。 A method for manufacturing a wire harness according to an eighth aspect includes (a) a step of superposing a plurality of non-woven members, and (b) sandwiching a laminate obtained by superposing the non-woven members from both sides. Including a recess capable of disposing at least a part of the wire harness main body by hot pressing, and manufacturing a plurality of divided protective bodies whose inner peripheral surface portion is softer than the outer peripheral surface portion; and (c) the plural Combining the plurality of divided protective bodies so as to accommodate at least a part of the wire harness main body in the divided protective bodies.
　第９の態様に係る保護部材は、内周側不織部材と外周側不織部材とが重ね合された積層体がワイヤーハーネス本体の少なくとも一部を覆う形状にホットプレスされることにより形成され、外周側表面部分よりも内周側表面部分が柔らかいものである。 The protective member according to the ninth aspect is formed by hot pressing a laminated body in which the inner peripheral side non-woven member and the outer peripheral side non-woven member are overlapped so as to cover at least a part of the wire harness body. The inner peripheral surface portion is softer than the outer peripheral surface portion.
　第１、第８又は第９の態様に係るワイヤーハーネスによると、保護部材のうち比較的硬い外周側表面部分によってワイヤーハーネス本体をしっかりと経路規制することができる。また、保護部材のうち比較的柔らかい内周側表面部分によって、保護部材とワイヤーハーネスとの接触による異音を抑制することができる。また、内周側不織部材と外周側不織部材とが重ね合された積層体をホットプレスしているため、外周側表面部分よりも内周側表面部分が柔らかくなるように容易に加工することができ、保護部材を容易に製造できる。 According to the wire harness according to the first, eighth, or ninth aspect, the route of the wire harness main body can be firmly regulated by the relatively hard outer peripheral surface portion of the protective member. Moreover, the noise by contact with a protection member and a wire harness can be suppressed by the comparatively soft inner peripheral surface part among protection members. Moreover, since the laminated body in which the inner peripheral side non-woven member and the outer peripheral side non-woven member are overlapped is hot-pressed, the inner peripheral side surface portion is easily processed to be softer than the outer peripheral side surface portion. The protective member can be easily manufactured.
　第２の態様によると、前記内周側不織部材と前記外周側不織部材とは、前記バインダの割合及び前記バインダの融点の少なくとも１つが異なるため、保護部材の内周側表面部分を柔らかく、外周側表面部分を硬くするように、容易に作り分けることができる。 According to the second aspect, the inner peripheral side non-woven member and the outer peripheral side non-woven member are different in at least one of the ratio of the binder and the melting point of the binder, so that the inner peripheral side surface portion of the protective member is softened. The outer peripheral surface portion can be easily made separately.
　また、保護部材の内周側表面部分は比較的柔らかいため、第３の態様のように、ワイヤーハーネス本体の少なくとも一部が前記保護部材の内周側表面部分に対して遊びがある状態で収容され、前記ワイヤーハーネス本体の少なくとも一部が前記保護部材内で動いても、ワイヤーハーネスと保護部材の内周側表面部分との接触による異音を抑制することができる。 Further, since the inner peripheral surface portion of the protective member is relatively soft, as in the third aspect, at least a part of the wire harness body is accommodated in a state where there is play with respect to the inner peripheral surface portion of the protective member. Even if at least a part of the wire harness body moves within the protective member, it is possible to suppress abnormal noise due to contact between the wire harness and the inner peripheral surface portion of the protective member.
　第４の態様によると、前記ワイヤーハーネス本体の少なくとも一部が、比較的柔らかく形成された保護部材の内周側表面部分によって挟まれているため、保護部材内でワイヤーハーネスが動き難くなり、保護部材とワイヤーハーネスとの接触による異音を効果的に抑制できる。 According to the 4th aspect, since at least one part of the said wire harness main body is pinched | interposed by the inner peripheral side surface part of the protective member formed comparatively softly, a wire harness becomes difficult to move within a protective member, and is protected. Abnormal noise due to contact between the member and the wire harness can be effectively suppressed.
　第５の態様によると、分割保護体は、前記内周側不織部材と前記外周側不織部材とが重ね合された積層体がその両面側から挟込まれてホットプレスされることにより形成されているため、保護部材の外周側表面部分を形成する部分に十分な熱及び圧力を加えて、より硬くなるように加工することができる。 According to the fifth aspect, the split protective body is formed by hot pressing the laminated body in which the inner circumferential nonwoven member and the outer circumferential nonwoven member are overlapped from both sides. Therefore, sufficient heat and pressure can be applied to the portion forming the outer peripheral side surface portion of the protective member to make it harder.
　第６の態様によると、複数の分割保護体がヒンジによって連結されているため、部品点数を少なくすることができる。 According to the sixth aspect, since the plurality of divided protective bodies are connected by the hinges, the number of parts can be reduced.
　第７の態様によると、前記複数の分割保護体は、それぞれ別体に形成されているため、それぞれの加工が容易となる。 According to the seventh aspect, since the plurality of divided protective bodies are formed separately from each other, each processing becomes easy.

　以下、実施形態に係るワイヤーハーネス、ワイヤーハーネスの製造方法及び保護部材について説明する。 Hereinafter, the wire harness according to the embodiment, the method for manufacturing the wire harness, and the protection member will be described.
　図１はワイヤーハーネス１０を示す斜視図であり、図２は図１のＩＩ－ＩＩ線断面図である。 FIG. 1 is a perspective view showing the wire harness 10, and FIG. 2 is a cross-sectional view taken along the line II-II in FIG.
　ワイヤーハーネス１０は、ワイヤーハーネス本体１２と、保護部材２０とを備える。 The wire harness 10 includes a wire harness body 12 and a protection member 20.
　ワイヤーハーネス本体１２は、少なくとも１本の電線１４を含む。ここでは、ワイヤーハーネス本体１２は、複数の電線１４が束ねられた部分を含んでおり、この部分が保護部材２０によって保護される。ワイヤーハーネス本体１２は途中で分岐していてもよい。ワイヤーハーネス本体１２には、光ファイバケーブル等が含まれていてもよい。ワイヤーハーネス本体の全体が保護部材２０によって保護されてもよい。 The wire harness body 12 includes at least one electric wire 14. Here, the wire harness body 12 includes a portion in which a plurality of electric wires 14 are bundled, and this portion is protected by the protection member 20. The wire harness body 12 may be branched in the middle. The wire harness body 12 may include an optical fiber cable or the like. The entire wire harness body may be protected by the protection member 20.
　上記ワイヤーハーネス本体１２は、車両における所定の配線形態に沿って配設された状態で、コネクタ接続等を介して各種車載電気部品に接続される。これにより、車載電気部品がワイヤーハーネス本体１２を介して相互に電気的に接続される。 The wire harness body 12 is connected to various in-vehicle electrical components through connector connection or the like in a state of being arranged along a predetermined wiring form in the vehicle. Thereby, the vehicle-mounted electrical components are electrically connected to each other via the wire harness body 12.
　保護部材２０は、内周側不織部材２２と外周側不織部材２４とが重ね合された積層体２６（後述する）がワイヤーハーネス本体１２の少なくとも一部を覆う形状にホットプレスされることにより形成されている。そして、ホットプレス加工後の内周側不織部材２２ａの内周側表面部分２２ｆが、同じくホットプレス加工後の外周側不織部材２４ａの外周側表面部分２４ｆよりも柔らかくなるように仕上げられている。 The protective member 20 is hot-pressed into a shape in which a laminated body 26 (described later) in which the inner circumferential non-woven member 22 and the outer circumferential non-woven member 24 are overlapped covers at least a part of the wire harness body 12. It is formed by. Then, the inner peripheral side surface portion 22f of the inner peripheral side non-woven member 22a after hot pressing is finished so as to be softer than the outer peripheral side surface portion 24f of the outer peripheral side non-woven member 24a after hot pressing. Yes.
　ここで、ホットプレスとは、不織部材に対して加熱処理及び不織部材を型に押付けて所定形状に形成する処理を施すことをいう。加熱処理と所定形状への形成処理とは、同時に行われてもよいし、或は、連続的に別々に行われてもよい。例えば、不織部材を圧縮状態で加熱した後、冷却により固まる前に所定の型に押付けて曲げることで、当該曲げ形状に維持できる。この実施形態に係る保護部材２０を加工するのに適したホットプレス加工の例については後にさらに詳述する。 Here, hot pressing refers to performing a heat treatment on a non-woven member and a process of pressing the non-woven member against a mold to form a predetermined shape. The heat treatment and the forming process into a predetermined shape may be performed simultaneously, or may be performed separately continuously. For example, after heating a non-woven member in a compressed state, the non-woven member can be maintained in the bent shape by being pressed against a predetermined mold and bent before being solidified by cooling. An example of hot pressing suitable for processing the protective member 20 according to this embodiment will be described in detail later.
　また、加工対象となる不織部材としては、少なくとも一部が溶融し或いは軟らかくなり、その後冷却工程を経て硬くなることが可能なものを用いることができる。このような不織部材として、基本繊維とバインダ（接着樹脂とも呼ばれる）とを含むものを用いることができる。バインダは、基本繊維の融点よりも低い融点を有する樹脂である。そして、不織部材を、基本繊維の融点より低く且つバインダの融点よりも高い温度に加熱することにより、バインダが溶融されて基本繊維間にしみ込む。この後、不織部材の温度が低下すると、バインダが凝固する。これにより、不織部材を加熱時の成形状態に維持することができる。また、凝固したバインダは、不織部材同士の接触箇所同士を接合することもできる。 Further, as the non-woven member to be processed, a member that can be at least partially melted or softened and then hardened through a cooling process can be used. As such a non-woven member, a material containing basic fibers and a binder (also called an adhesive resin) can be used. The binder is a resin having a melting point lower than that of the basic fiber. Then, by heating the nonwoven member to a temperature lower than the melting point of the basic fiber and higher than the melting point of the binder, the binder is melted and soaks between the basic fibers. Thereafter, when the temperature of the nonwoven member is lowered, the binder is solidified. Thereby, a nonwoven member can be maintained in the shaping | molding state at the time of a heating. Moreover, the solidified binder can also join the contact parts of nonwoven members.
　不織部材の基本繊維としては、バインダの融点で繊維状態を保ち得ればよく、樹脂繊維の他、ガラス繊維等の各種繊維を用いることができる。また、バインダは、基本繊維の融点より低い融点を有する熱可塑性樹脂繊維を用いることができる。例えば、基本繊維とバインダとの組合せとしては、基本繊維をＰＥＴ（ポリエチレンテレフタレート）の樹脂繊維とし、バインダをＰＥＴとＰＥＩ（ポリエチレンイソフタレート）との共重合樹脂としたものが挙げられる。 As the basic fiber of the non-woven member, it is only necessary to maintain the fiber state with the melting point of the binder, and various fibers such as glass fibers can be used in addition to resin fibers. Moreover, the thermoplastic resin fiber which has melting | fusing point lower than melting | fusing point of a basic fiber can be used for a binder. For example, as a combination of a basic fiber and a binder, there may be mentioned one in which the basic fiber is a resin fiber of PET (polyethylene terephthalate) and the binder is a copolymer resin of PET and PEI (polyethylene isophthalate).
　上記のようにホットプレスを行った後、保護部材２０の内周側表面部分２２ｆを柔らかく加工し、保護部材２０の外周側表面部分２４ｆを硬く加工するためには、内周側不織部材２２と外周側不織部材２４とで異なる性質のものを用いるとよい。すなわち、同一条件でホットプレスした場合に、外周側不織部材２４として、内周側不織部材２２よりも容易に硬くなることが可能なものを用いるとよい。 After hot pressing as described above, in order to soften the inner peripheral surface portion 22f of the protective member 20 and harden the outer peripheral surface portion 24f of the protective member 20, the inner peripheral non-woven member 22 is processed. It is preferable to use different materials for the outer circumferential side non-woven member 24. In other words, when hot pressing is performed under the same conditions, it is preferable to use a material that can be hardened more easily than the inner circumferential non-woven member 22 as the outer circumferential non-woven member 24.
　一例としては、外周側不織部材２４のバインダの割合を、内周側不織部材２２のバインダの割合よりも大きくするとよい。これにより、内周側不織部材２２と外周側不織部材２４とを同じ条件（温度、時間等）に加熱した場合に、外周側不織部材２４においてより多くのバインダが溶融して基本繊維をより強固に接合する。このため、内周側不織部材２２と外周側不織部材２４とを同じ温度に加熱した場合に、外周側不織部材２４の方がより硬くなる。 As an example, the binder ratio of the outer circumferential nonwoven member 24 may be larger than the binder ratio of the inner circumferential nonwoven member 22. Thereby, when the inner peripheral side non-woven member 22 and the outer peripheral side non-woven member 24 are heated to the same conditions (temperature, time, etc.), more binder is melted in the outer peripheral side non-woven member 24 and the basic fiber is melted. Are joined more firmly. For this reason, when the inner peripheral side non-woven member 22 and the outer peripheral side non-woven member 24 are heated to the same temperature, the outer peripheral side non-woven member 24 becomes harder.
　また、内周側不織部材２２のバインダと外周側不織部材２４のバインダとで、異なる融点のものを用いてもよい。すなわち、外周側不織部材２４のバインダとして、内周側不織部材２２のバインダの融点よりも低い融点を有するものを用いてもよい。この場合、内周側不織部材２２のバインダと外周側不織部材２４のバインダとして、異なる樹脂製のものを用いてもよいし、或は、重合度が異なる樹脂を用いてもよい。 Also, a material having a different melting point may be used for the binder of the inner peripheral side non-woven member 22 and the binder of the outer peripheral side non-woven member 24. That is, as the binder of the outer peripheral side non-woven member 24, a binder having a melting point lower than the melting point of the binder of the inner peripheral side non-woven member 22 may be used. In this case, as the binder of the inner peripheral side non-woven member 22 and the binder of the outer peripheral side non-woven member 24, those made of different resins may be used, or resins having different degrees of polymerization may be used.
　また、内周側不織部材２２と外周側不織部材２４とで、バインダの割合及び融点の双方が異なっていてもよい。 Also, the inner peripheral side non-woven member 22 and the outer peripheral side non-woven member 24 may have different binder ratios and melting points.
　その他、内周側不織部材２２と外周側不織部材２４とで、かさ密度等が異なっていてもよい。 In addition, the bulk density and the like may be different between the inner peripheral side non-woven member 22 and the outer peripheral side non-woven member 24.
　ここでは、保護部材２０は、ワイヤーハーネス本体１２の少なくとも一部を覆う形状として、筒状、より具体的には、扁平な方形筒状に形成されている。ここでは、保護部材２０は、直線状に延在しているが、途中で曲っていてもよいし、また、途中で分岐していてもよい。 Here, the protective member 20 is formed in a cylindrical shape, more specifically, a flat rectangular cylindrical shape, as a shape covering at least a part of the wire harness main body 12. Here, the protective member 20 extends in a straight line, but may be bent in the middle or may be branched in the middle.
　また、保護部材２０は、複数の分割保護体２７Ａ、２７Ｂの組合わせによって構成されている。より具体的には、保護部材２０は、扁平な方形筒状の短辺部分で２分割された一対の分割保護体２７Ａ、２７Ｂを含む。また、一対の分割保護体２７Ａ、２７Ｂは、後述するように、ヒンジ等で連結されず、別体に形成されている。 Further, the protective member 20 is constituted by a combination of a plurality of divided protective bodies 27A and 27B. More specifically, the protection member 20 includes a pair of divided protective bodies 27A and 27B that are divided into two by a flat rectangular cylindrical short side portion. Further, as will be described later, the pair of split protectors 27A and 27B are not connected by a hinge or the like and are formed separately.
　一対の分割保護体２７Ａ、２７Ｂは、収容本体部２８Ａ、２８Ｂと、縁部２９Ａ、２９Ｂとを含む。 The pair of split protectors 27A and 27B includes housing main body portions 28A and 28B and edge portions 29A and 29B.
　収容本体部２８Ａ、２８Ｂは、ワイヤーハーネス本体１２の保護対象部分の配索経路に応じた半筒形状、ここでは、半角筒形状、より具体的には、扁平な半角筒形状に形成されている。収容本体部２８Ａ、２８Ｂ内には、浅い収容凹部が形成されており、この収容凹部は、収容本体部２８Ａ、２８Ｂの両端部及び両端部間の一側に向けて開口している。 The housing main bodies 28A and 28B are formed in a half cylinder shape corresponding to the route of the portion to be protected of the wire harness body 12, here, a half square cylinder shape, more specifically, a flat half square cylinder shape. . Shallow housing recesses are formed in the housing main bodies 28A and 28B, and the housing recesses open toward both ends of the housing main bodies 28A and 28B and one side between the both ends.
　収容本体部２８Ａ、２８Ｂの両側部に外方に張出すようにして縁部２９Ａ、２９Ｂが形成されている。縁部２９Ａ、２９Ｂは、収容本体部２８Ａ、２８Ｂの両側縁部を結ぶ方向に沿って延びる細長板状に形成されている。 Edge portions 29A and 29B are formed so as to project outward on both sides of the housing main body portions 28A and 28B. The edge portions 29A and 29B are formed in an elongated plate shape extending along a direction connecting both side edge portions of the housing main body portions 28A and 28B.
　また、上記各分割保護体２７Ａ、２７Ｂのそれぞれは、内周側不織部材２２と外周側不織部材２４とが重ね合された積層体２６がその両面側、つまり、保護部材２０の内周面側及び外周面側から挟込まれた状態でホットプレスされることにより形成されている。つまり、分割保護体２７Ａ、２７Ｂの両面は、ホットプレス用の型面によって加工された性状を呈している。 Each of the divided protective bodies 27A and 27B includes a laminated body 26 in which the inner circumferential non-woven member 22 and the outer circumferential non-woven member 24 are overlapped, that is, the inner circumference of the protective member 20. It is formed by hot pressing while being sandwiched from the surface side and the outer peripheral surface side. In other words, both surfaces of the split protectors 27A and 27B have the properties processed by the hot press mold surface.
　そして、一対の分割保護体２７Ａ、２７Ｂ間にワイヤーハーネス本体１２の保護対象部分を収容した状態で、一対の分割保護体２７Ａ、２７Ｂの両側部同士を突合わせると、互いの縁部２９Ａ、２９Ｂが面接触した状態で突合わされて接合される。これにより、ワイヤーハーネス本体１２の少なくとも一部を保護する保護部材２０が構成される。縁部２９Ａ、２９Ｂ同士の接合は、両面テープ、超音波接合、熱溶着、ステープラ等により行うことができる。 And when the protection object part of the wire harness main body 12 is accommodated between a pair of division | segmentation protection bodies 27A and 27B, when both sides of a pair of division | segmentation protection bodies 27A and 27B are faced | matched, mutual edge part 29A, 29B Are brought into contact with each other while being in surface contact. Thereby, the protection member 20 which protects at least one part of the wire harness main body 12 is comprised. The edges 29A and 29B can be joined to each other by double-sided tape, ultrasonic joining, heat welding, stapler, or the like.
　なお、ここでは、一対の分割保護体２７Ａ、２７Ｂは、互いの接合面を介して面対称形状に形成されているが必ずしもその必要はない。例えば、一対の分割保護体の一方側を他方側より深い形状に形成してもよい。また、分割保護体の一方が平板状に形成されていてもよい。もっとも、一対の分割保護体の両側縁部がなるべく多くの箇所で対向していることが好ましい。 In addition, although a pair of division | segmentation protector 27A, 27B is formed in the plane symmetrical shape through the mutual joint surface here, it is not necessarily required. For example, one side of the pair of split protectors may be formed deeper than the other side. Moreover, one side of the division | segmentation protector may be formed in flat form. But it is preferable that the both-sides edge part of a pair of division | segmentation protector has opposed in as many locations as possible.
　ここでは、ワイヤーハーネス本体１２を構成する電線１４がバラバラな状態で一対の分割保護体２７Ａ、２７Ｂ間に充填状に収容された状態を示しているが、ワイヤーハーネス本体１２を構成する各電線１４が円形状断面を呈するように、粘着テープ等の結束部材によって結束されていてもよい。 Here, although the electric wire 14 which comprises the wire harness main body 12 has shown the state accommodated in the filling state between a pair of division | segmentation protectors 27A and 27B in the state which was separated, each electric wire 14 which comprises the wire harness main body 12 is shown. May be bound by a binding member such as an adhesive tape so as to exhibit a circular cross section.
　ワイヤーハーネス本体１２の少なくとも一部を保護部材２０内に収容する場合、ワイヤーハーネス本体１２の当該一部は、保護部材２０の内周側表面部分２２ｆに対して遊びがある状態で収容されていてもよい。 When at least a part of the wire harness main body 12 is accommodated in the protection member 20, the part of the wire harness main body 12 is accommodated in a state where there is play with respect to the inner peripheral surface portion 22 f of the protection member 20. Also good.
　例えば、ワイヤーハーネス本体１２の少なくとも一部が円形状断面を呈するように結束されている場合を想定すると、図３に示すように、一対の分割保護体２７Ａ、２７Ｂにおいて対向する内周側表面部分２２ｆ間の間隔寸法Ｈが、ワイヤーハーネス本体１２のうち収容対象となる結束された部分の直径Ｒ１よりも大きく設定されていてもよい。この場合、ワイヤーハーネス本体１２は、保護部材２０内で動けるものの、当該ワイヤーハーネス本体１２は保護部材２０内で比較的柔らかい内周側表面部分２２ｆに接触する。このため、ワイヤーハーネス本体１２が内周側表面部分２２ｆに接触したとしても、異音の発生は抑制される。 For example, assuming a case where at least a part of the wire harness body 12 is bound so as to exhibit a circular cross section, as shown in FIG. 3, the inner peripheral surface portions facing each other in the pair of split protectors 27A and 27B The interval dimension H between 22f may be set larger than the diameter R1 of the bound portion of the wire harness main body 12 to be accommodated. In this case, although the wire harness main body 12 can move within the protection member 20, the wire harness main body 12 contacts the relatively soft inner peripheral surface portion 22 f within the protection member 20. For this reason, even if the wire harness main body 12 contacts the inner peripheral side surface portion 22f, the generation of abnormal noise is suppressed.
　また、ワイヤーハーネス本体１２の少なくとも一部を保護部材２０内に収容する場合、ワイヤーハーネス本体１２の当該一部は、保護部材２０の内周側表面部分２２ｆによって挟まれた状態で収容されていてもよい。 Further, when at least a part of the wire harness body 12 is accommodated in the protection member 20, the part of the wire harness body 12 is accommodated in a state of being sandwiched by the inner peripheral surface portion 22 f of the protection member 20. Also good.
　例えば、ワイヤーハーネス本体１２の少なくとも一部が円形状断面を呈するように結束されている場合を想定すると、図４に示すように、一対の分割保護体２７Ａ、２７Ｂにおいて対向する内周側表面部分２２ｆ間の間隔寸法Ｈが、ワイヤーハーネス本体１２のうち収容対象となる結束された部分の直径Ｒ２よりも小さく設定されていてもよい。この場合、ワイヤーハーネス本体１２の当該部分は、保護部材２０の内周側表面部分２２ｆを凹ませるように弾性変形させた状態で、対向する内周側表面部分２２ｆ間に挟込まれる。このため、ワイヤーハーネス本体１２の当該部分は、対向する内周側表面部分２２ｆを結ぶ方向及びこれに直交する方向にも動き難い。従って、ワイヤーハーネス本体１２が内周側表面部分２２ｆに接触した状態が維持され、それらの間での打音等が抑制され、やはり異音の発生は抑制される。 For example, assuming a case where at least a part of the wire harness body 12 is bound so as to exhibit a circular cross section, as shown in FIG. 4, the inner peripheral surface portions facing each other in the pair of divided protective bodies 27A and 27B The interval dimension H between 22f may be set smaller than the diameter R2 of the bundled portion of the wire harness body 12 to be accommodated. In this case, the said part of the wire harness main body 12 is pinched | interposed between the inner peripheral side surface parts 22f which oppose in the state elastically deformed so that the inner peripheral side surface part 22f of the protection member 20 might be dented. For this reason, the said part of the wire harness main body 12 is hard to move also in the direction which ties the inner peripheral side surface part 22f which opposes, and the direction orthogonal to this. Therefore, the state in which the wire harness main body 12 is in contact with the inner peripheral surface portion 22f is maintained, and the hitting sound or the like between them is suppressed, and the generation of abnormal noise is also suppressed.
　なお、ワイヤーハーネス本体１２が途中で分岐等すれば、ワイヤーハーネス本体１２の太さは途中で変り得る。また、保護部材２０自体の大きさも途中で代えられてもよい。このため、保護部材２０において、ワイヤーハーネス本体１２を遊びのある状態で収容した部分と、ワイヤーハーネス本体１２を挟込んだ状態で収容した部分とが混在していてもよい。 In addition, if the wire harness main body 12 branches on the way, the thickness of the wire harness main body 12 may change on the way. Further, the size of the protective member 20 itself may be changed in the middle. For this reason, in the protection member 20, the part which accommodated the wire harness main body 12 in the state with play, and the part accommodated in the state which pinched | interposed the wire harness main body 12 may be mixed.
　なお、保護部材２０は、３つの分割保護体の組合わせによって構成されていてもよい。 In addition, the protection member 20 may be comprised by the combination of three division | segmentation protectors.
　上記ワイヤーハーネス１０の製造方法例について説明する。 An example of a method for manufacturing the wire harness 10 will be described.
　まず、図５に示すように、内周側不織部材２２と外周側不織部材２４とを重ね合せる。内周側不織部材２２と外周側不織部材２４との間に他の不織部材が介在していてもよい。また、ここでは、内周側不織部材２２と外周側不織部材２４とは同じ大きさ、形状であり、相互に全体に亘って存在する形態とされているが、内周側不織部材２２或は外周側不織部材２４が相手側に対して部分的に省略されていてもよい。 First, as shown in FIG. 5, the inner peripheral side non-woven member 22 and the outer peripheral side non-woven member 24 are overlapped. Another non-woven member may be interposed between the inner peripheral side non-woven member 22 and the outer peripheral side non-woven member 24. In addition, here, the inner peripheral side non-woven member 22 and the outer peripheral side non-woven member 24 have the same size and shape, and are in a form that exists over the whole. 22 or the outer peripheral side non-woven member 24 may be partially omitted with respect to the other party.
　次に、図６及び図７に示すように、ホットプレス型５０を用いて、内周側不織部材２２と外周側不織部材２４との積層体２６をホットプレスする。 Next, as shown in FIGS. 6 and 7, using a hot press die 50, the laminate 26 of the inner peripheral side non-woven member 22 and the outer peripheral side non-woven member 24 is hot pressed.
　このホットプレス型５０は、下型５２と、上型６２とを備える。 The hot press die 50 includes a lower die 52 and an upper die 62.
　下型５２は、熱伝導性に優れた金属等により形成された長尺部材であり、その一主面（上面）に下型面５３が形成されている。下型面５３は、分割保護体２７Ａ、２７Ｂの外周表面を形成する部分であり、幅方向中央で深く、幅方方向両側で段部を介して浅くなる、溝形状に形成されている。下型面５３の長手方向の寸法は、ワイヤーハーネス本体１２のうち保護対象部分となる部分の長さ寸法と同一かそれよりも長い程度に設定されている。下型面５３は、ワイヤーハーネス本体１２における保護対象部分を車体に配設した場合の経路に応じて延びる形状に形成されている。 The lower mold 52 is a long member formed of a metal having excellent thermal conductivity, and the lower mold surface 53 is formed on one main surface (upper surface) thereof. The lower mold surface 53 is a portion that forms the outer peripheral surface of the split protectors 27A and 27B, and is formed in a groove shape that is deep at the center in the width direction and shallower through the step portions on both sides in the width direction. The longitudinal dimension of the lower mold surface 53 is set to be equal to or longer than the length dimension of the portion of the wire harness body 12 that is to be protected. The lower mold surface 53 is formed in a shape that extends in accordance with the path when the protection target portion of the wire harness body 12 is disposed on the vehicle body.
　上型６２は、熱伝導性に優れた金属等により形成された長尺部材であり、その一主面（下面）に上型面６３が形成されている。上型面６３は、細長い突起形状であり、幅方向中央で高く、幅方向両側部で段部を介して低くなる形状に形成されている。上型面６３の幅は、上記下型面５３の上方開口を塞ぎつつ当該下型面５３内に配設可能な大きさに設定されている。また、上型面６３は、上記下型面５３の形状に応じて延びる形状に形成されている。 The upper mold 62 is a long member made of a metal having excellent thermal conductivity, and the upper mold surface 63 is formed on one main surface (lower surface) thereof. The upper mold surface 63 has a long and narrow projection shape, and is formed in a shape that is high at the center in the width direction and lower at both side portions in the width direction through stepped portions. The width of the upper mold surface 63 is set to a size that can be disposed in the lower mold surface 53 while closing the upper opening of the lower mold surface 53. The upper mold surface 63 is formed in a shape extending according to the shape of the lower mold surface 53.
　そして、この上型面６３が下型面５３内に配設されることにより、それらの間で、分割保護体２７Ａ、２７Ｂを形成可能なスペースが形成される。なお、下型５２及び上型６２には、ヒーター等の加熱部５４、６４が設けられている。 Then, by arranging the upper mold surface 63 in the lower mold surface 53, a space in which the divided protective bodies 27A and 27B can be formed is formed between them. The lower mold 52 and the upper mold 62 are provided with heating parts 54 and 64 such as a heater.
　上記ホットプレス型５０を用いてホットプレス加工を行う方法について説明する。 A method for performing hot pressing using the hot pressing die 50 will be described.
　まず、シート状の内周側不織部材２２とシート状の外周側不織部材２４との積層体２６を、下型面５３内に配設する。なお、下型面５３上で、内周側不織部材２２と外周側不織部材２４との重ね合せ作業を行ってもよい。 First, the laminated body 26 of the sheet-like inner peripheral side non-woven member 22 and the sheet-like outer peripheral side non-woven member 24 is disposed in the lower mold surface 53. In addition, on the lower mold | type surface 53, you may superimpose the inner peripheral side non-woven member 22 and the outer peripheral side non-woven member 24. FIG.
　この後、上型６２の上型面６３を下型面５３内に配設し、下型面５３及び上型面６３によって積層体２６をその両面側から挟込む。すると、積層体２６が下型５２及び上型６２に接触する部分を中心として加熱される。なお、下型５２の加熱温度と上型６２の加熱温度とは同じでなくてもよい。分割保護体２７Ａ、２７Ｂの外周側表面部分２４ｆを効果的に硬くするために、下型５２の加熱温度を上型６２の加熱温度よりも高くしてもよい。 Thereafter, the upper mold surface 63 of the upper mold 62 is disposed in the lower mold surface 53, and the laminate 26 is sandwiched between the lower mold surface 53 and the upper mold surface 63 from both sides thereof. Then, the laminated body 26 is heated around a portion that contacts the lower mold 52 and the upper mold 62. Note that the heating temperature of the lower mold 52 and the heating temperature of the upper mold 62 may not be the same. In order to effectively harden the outer peripheral side surface portion 24f of the split protectors 27A and 27B, the heating temperature of the lower mold 52 may be set higher than the heating temperature of the upper mold 62.
　この後、積層体２６が冷却されると、上記下型５２及び上型６２間で、内周側不織部材２２ａの内周側表面部分２２ｆが下型面５３の形状に応じた形状で硬化し、外周側不織部材２４の外周側表面部分２４ｆが上型面６３の形状に応じた形状で硬化する。また、内周側不織部材２２ａと外周側不織部材２４ａとは互いのバインダ樹脂によって重ね合せ状態に接合される。これにより、分割保護体２７Ａ、２７Ｂが形成される。 Thereafter, when the laminate 26 is cooled, the inner peripheral side surface portion 22f of the inner peripheral non-woven member 22a is cured between the lower mold 52 and the upper mold 62 in a shape corresponding to the shape of the lower mold surface 53. Then, the outer peripheral side surface portion 24 f of the outer peripheral side non-woven member 24 is cured in a shape corresponding to the shape of the upper mold surface 63. Moreover, the inner peripheral side non-woven member 22a and the outer peripheral side non-woven member 24a are joined to each other by a binder resin. Thereby, the division | segmentation protectors 27A and 27B are formed.
　この後、分割保護体２７Ａ、２７Ｂがホットプレス型５０から取出される。一対の分割保護体２７Ａ、２７Ｂは、同じホットプレス型５０によって形成されてもよいし、別のホットプレス型によって形成されてもよい。 Thereafter, the split protectors 27A and 27B are taken out from the hot press die 50. The pair of split protectors 27A and 27B may be formed by the same hot press die 50 or by another hot press die.
　そして、図８に示すように、上記のように形成された一対の分割保護体２７Ａ、２７Ｂを準備し、一対の分割保護体２７Ａ、２７Ｂ内にワイヤーハーネス本体１２の少なくとも一部を収容するように、一対の分割保護体２７Ａ、２７Ｂを合体させる。 And as shown in FIG. 8, a pair of division | segmentation protection bodies 27A and 27B formed as mentioned above are prepared, and at least one part of the wire harness main body 12 is accommodated in a pair of division | segmentation protection bodies 27A and 27B. The pair of split protectors 27A and 27B are combined.
　両者の合体は、上記したように、突合わされた縁部２９Ａ、２９Ｂ同士を両面テープで接着すること等により行うことができる。 The coalescence of both can be performed by adhering the butt edges 29A and 29B with a double-sided tape as described above.
　以上のように構成されたワイヤーハーネス１０、保護部材２０及びワイヤーハーネス１０の製造方法によると、保護部材２０のうち比較的硬い外周側表面部分２４ｆによってワイヤーハーネス本体１２をしっかりと経路規制することができる。また、保護部材２０のうち比較的硬い外周側表面部分２４ｆによってワイヤーハーネス本体１２をしっかりと保護することもできる。また、保護部材２０のうち比較的柔らかい内周側表面部分２２ｆによって保護部材２０とワイヤーハーネス本体１２との接触による異音を抑制することができる。 According to the manufacturing method of the wire harness 10, the protection member 20, and the wire harness 10 configured as described above, the route of the wire harness body 12 can be firmly regulated by the relatively hard outer peripheral surface portion 24 f of the protection member 20. it can. Moreover, the wire harness main body 12 can also be firmly protected by the relatively hard outer peripheral surface portion 24f of the protective member 20. Moreover, abnormal noise due to contact between the protection member 20 and the wire harness body 12 can be suppressed by the relatively soft inner peripheral surface portion 22 f of the protection member 20.
　また、保護部材２０は、内周側不織部材２２と外周側不織部材２４とが重ね合された積層体２６が、ワイヤーハーネス本体１２の少なくとも一部を覆う形状にホットプレスされることにより形成されているため、内周側不織部材２２と外周側不織部材２４とで異なる性質のものを用いること等により、保護部材２０の内周側表面部分２２ｆを柔らかく、保護部材２０の外周側表面部分２４ｆを硬くするように、容易に作り分けることができ、保護部材２０を容易に製造できる。 Further, the protective member 20 is hot-pressed into a shape in which the laminated body 26 in which the inner peripheral side non-woven member 22 and the outer peripheral side non-woven member 24 are overlapped covers at least a part of the wire harness body 12. Since the inner circumferential side non-woven member 22 and the outer circumferential side non-woven member 24 have different properties, the inner circumferential side surface portion 22f of the protective member 20 is softened and the outer circumference of the protective member 20 is increased. The side surface portion 24f can be easily made so as to be hard, and the protective member 20 can be easily manufactured.
　より具体的には、内周側不織部材２２と外周側不織部材２４とで、バインダの割合及びバインダの融点の少なくとも１つを異ならせることにより、同じホットプレス条件下においても、容易に加工後の硬さを異ならせることができる。 More specifically, the inner peripheral side non-woven member 22 and the outer peripheral side non-woven member 24 can be easily changed even under the same hot press conditions by making the ratio of the binder and the melting point of the binder different. The hardness after processing can be varied.
　そして、比較的硬く形成された外周側表面部分２４ｆによって、十分なワイヤーハーネス本体１２の経路規制機能、保護機能（耐摩耗性等）を持たせることができる。 And, it is possible to provide the wire harness body 12 with a sufficient path regulating function and protective function (wear resistance, etc.) by the outer peripheral surface portion 24f formed relatively hard.
　また、比較的柔らかく形成された内周側表面部分２２ｆによって、本ワイヤーハーネス１０と保護部材２０との間での異音を抑制することができる。すなわち、上記したように、ワイヤーハーネス本体１２の少なくとも一部が保護部材２０の内周側表面部分２２ｆに対して遊びがある状態で収容されている場合等には、当該ワイヤーハーネス本体１２が保護部材２０内で動いたとしても比較的柔らかい内周側表面部分２２ｆに接触する。このため、ワイヤーハーネス本体１２と内周側表面部分２２ｆとの間での異音の発生は抑制される。また、ワイヤーハーネス本体１２の少なくとも一部が保護部材２０の内周側表面部分２２ｆによって挟まれた状態で収容されている場合には、保護部材２０内でのワイヤーハーネス本体１２自体の動きが抑制され、これにより、ワイヤーハーネス本体１２と保護部材２０との接触音が抑制される。これにより、経路規制機能、保護性能、接触音抑制機能を有する保護部材２０を、少ない部品点数で、かつ、軽量化された構成で実現することが可能となる。 Further, abnormal noise between the wire harness 10 and the protective member 20 can be suppressed by the inner peripheral surface portion 22f formed relatively soft. That is, as described above, when at least a part of the wire harness body 12 is accommodated in a state where there is play with respect to the inner peripheral surface portion 22f of the protection member 20, the wire harness body 12 is protected. Even if it moves in the member 20, it contacts the relatively soft inner peripheral surface portion 22f. For this reason, generation | occurrence | production of the abnormal noise between the wire harness main body 12 and the inner peripheral side surface part 22f is suppressed. Moreover, when at least a part of the wire harness body 12 is accommodated in a state sandwiched between the inner peripheral surface portions 22f of the protection member 20, the movement of the wire harness body 12 itself in the protection member 20 is suppressed. Thereby, the contact sound of the wire harness main body 12 and the protection member 20 is suppressed. Thereby, it becomes possible to implement | achieve the protection member 20 which has a path | route control function, a protection performance, and a contact sound suppression function with a small number of parts, and the weight-reduced structure.
　また、保護部材２０自体によってワイヤーハーネス本体１２と保護部材２０との間での異音が抑制される結果、ワイヤーハーネス本体１２を保護部材２０に固定する他の構成を削減又は無くすることが可能となる。例えば、プロテクタに対してワイヤーハーネスが動いて接触音を発生させることを抑制するため、プロテクタの端部とワイヤーハーネスとを粘着テープ又は結束バンド等で固定する構造、プロテクタ内でウレタン等の柔らかい部材によりワイヤーハーネス本体１２の動きを抑制する構造を削減、簡易化又は無くすることが可能となる。この点からも、構造の簡易化、部品点数の削減、ワイヤーハーネスの製造の簡易化等を期待することができる。 Moreover, as a result of the abnormal noise between the wire harness body 12 and the protection member 20 being suppressed by the protection member 20 itself, it is possible to reduce or eliminate other configurations for fixing the wire harness body 12 to the protection member 20. It becomes. For example, in order to prevent the wire harness from moving against the protector and generating contact noise, a structure in which the end of the protector and the wire harness are fixed with an adhesive tape or a binding band, or a soft member such as urethane in the protector. Thus, the structure for suppressing the movement of the wire harness body 12 can be reduced, simplified, or eliminated. From this point, simplification of the structure, reduction of the number of parts, simplification of manufacture of the wire harness, and the like can be expected.
　また、上記保護部材２０は、一対の分割保護体２７Ａ、２７Ｂに分割されているため、複数の不織部材２２、２４を重ね合せた積層体２６をその両面側から挟込んでホットプレスすることができる。これにより、保護部材２０の外周側表面部分２４ｆを十分に加熱及び加圧して、十分に硬くなるように加工することができ、経路規制機能、保護性能の向上を図ることができる。 Moreover, since the said protection member 20 is divided | segmented into a pair of division | segmentation protection body 27A, 27B, the laminated body 26 which piled up the some nonwoven member 22 and 24 is inserted | pinched from the both surfaces side, and is hot-pressed. Can do. Thereby, the outer peripheral side surface portion 24f of the protection member 20 can be sufficiently heated and pressurized to be processed so as to be sufficiently hard, and the path regulation function and the protection performance can be improved.
　もっとも、保護部材２０を、一対の分割保護体２７Ａ、２７Ｂの分割構造として、積層体２６をその両面側から挟込んでホットプレスすることは必須ではない。 However, it is not essential to hot-press the protective member 20 as a divided structure of a pair of divided protective bodies 27A and 27B by sandwiching the laminated body 26 from both sides.
　例えば、複数の不織部材の積層体を筒状に丸めた状態で、その内外周両側から加圧及び加熱するようにしてもよい。また、例えば、複数の不織部材の積層体をワイヤーハーネス本体１２の少なくとも一部に巻付けた状態で、当該積層体を外周側から加熱するようにしてもよい。 For example, in a state where a laminated body of a plurality of non-woven members is rolled into a cylindrical shape, it may be pressurized and heated from both the inner and outer peripheral sides. Further, for example, the laminated body may be heated from the outer peripheral side in a state in which a laminated body of a plurality of nonwoven members is wound around at least a part of the wire harness body 12.
　また、一対の分割保護体２７Ａ、２７Ｂは、別体に形成されているため、それぞれの加工が容易となる。特に、保護部材２０の形状が複雑に曲っているような場合には、一対の分割保護体２７Ａ、２７Ｂが別体に形成されていることは有効である。 In addition, since the pair of split protective bodies 27A and 27B are formed separately, each processing becomes easy. In particular, when the shape of the protective member 20 is bent in a complicated manner, it is effective that the pair of divided protective bodies 27A and 27B are formed separately.
　もっとも、図９及び図１０に示すように、保護部材２０に対応する保護部材１２０が、複数（ここでは一対）の分割保護体１２７Ａ、１２７Ｂを含み、複数の分割保護体２７Ａ、２７Ｂがヒンジ部１２７Ｈによって開閉可能に連結されていてもよい。 However, as shown in FIGS. 9 and 10, the protective member 120 corresponding to the protective member 20 includes a plurality (here, a pair) of divided protective bodies 127A and 127B, and the plurality of divided protective bodies 27A and 27B are hinge portions. It may be connected by 127H so that opening and closing is possible.
　ここでは、一対の分割保護体１２７Ａ、１２７Ｂの両側部の一方側の縁部２９Ａ、２９Ｂが省略され、代りに、一対の分割保護体１２７Ａ、１２７Ｂの側部同士がヒンジ部１２７Ｈで連結されている。 Here, the edge portions 29A and 29B on one side of both sides of the pair of split protectors 127A and 127B are omitted, and instead, the side portions of the pair of split protectors 127A and 127B are connected by a hinge portion 127H. Yes.
　ヒンジ部１２７Ｈは、一対の分割保護体１２７Ａ、１２７Ｂのその他の部分よりも柔らかく形成されていることが好ましい。例えば、ヒンジ部１２７Ｈを、他の部分よりも圧縮度合を低くすること、加熱温度を低くすること等により柔らかく形成することができる。 The hinge portion 127H is preferably formed to be softer than the other portions of the pair of split protectors 127A and 127B. For example, the hinge part 127H can be softly formed by lowering the degree of compression than other parts, lowering the heating temperature, or the like.
　上記のような一対の分割保護体１２７Ａ、１２７Ｂは、上記下型面５３に相当する部分１５３、１５３を２つ並設して形成した構成の下型１５２と、上記上型面６３に相当する部分１６３、１６３を２つ並設した形成した構成の上型１６２とを用い、それらの間で積層体１２６をホットプレスすることで製造することができる。この場合に、例えば、下型１５２と上型１６２のうち部分１５３、１５３の間の部分と部分１６３、１６３との間の部分（つまり、一対の分割保護体１２７Ａ、１２７Ｂを繋ぐ部分を形成する部分）に、積層体１２６の圧縮度合を小さくする凹部１７０を形成して、ヒンジ部１２７Ｈを形成するとよい。 The pair of split protectors 127A and 127B as described above corresponds to the lower mold 152 configured by arranging two portions 153 and 153 corresponding to the lower mold surface 53 side by side, and the upper mold surface 63. The laminated body 126 can be manufactured by hot pressing between the upper mold 162 having a configuration in which two portions 163 and 163 are arranged side by side. In this case, for example, of the lower mold 152 and the upper mold 162, a portion between the portions 153 and 153 and a portion between the portions 163 and 163 (that is, a portion connecting the pair of split protectors 127A and 127B is formed. The hinge part 127H may be formed by forming a concave part 170 that reduces the degree of compression of the stacked body 126 in the part).
　そして、一方の分割保護体１２７Ａ内にワイヤーハーネス本体１２の少なくとも一部を配設した状態で、ヒンジ部１２７Ｈを基点として、他方の分割保護体１２７Ｂを一方の分割保護体１２７Ａ上に被せるように閉じ合わせ、ヒンジ部１２７Ｈの反対側で縁部２９Ａ、２９Ｂ同士を接合すると、保護部材１２０が構成される。 Then, in a state where at least a part of the wire harness main body 12 is disposed in one split protector 127A, the other split protector 127B is placed on one split protector 127A with the hinge portion 127H as a base point. When the edges 29A and 29B are joined to each other on the opposite side of the hinge portion 127H, the protective member 120 is configured.
　この変形例によっても、一方の分割保護体を別体にすることによる利点を除いて、上記実施形態と同様の効果を得ることができる。 This modification can also obtain the same effects as those of the above embodiment except for the advantage of making one of the divided protective bodies separate.
　また、一対の分割保護体１２７Ａ、１２７Ｂがヒンジ部１２７Ｈを介して連結されているため、部品点数を少なくすることができ、その管理、製造が容易となる。 Further, since the pair of split protectors 127A and 127B are connected via the hinge portion 127H, the number of parts can be reduced, and the management and manufacture thereof are facilitated.
　以上のようにこの発明は詳細に説明されたが、上記した説明は、すべての局面において、例示であって、この発明がそれに限定されるものではない。例示されていない無数の変形例が、この発明の範囲から外れることなく想定され得るものと解される。 Although the present invention has been described in detail as described above, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
