FIG. 4 is an explanatory view showing a state in which the wiring module 10 is attached to the vehicle.

配線モジュール10は、配線部としてのワイヤーハーネス12と、プロテクタ20と、結束部材50とを備える。   The wiring module 10 includes a wire harness 12 as a wiring portion, a protector 20, and a binding member 50.

ワイヤーハーネス12は、複数の電線13が束ねられることによって構成されている。ここでは、ワイヤーハーネス12は、幹線12aの延在方向中間部から分岐線12bが分岐するように、複数の電線13が束ねられた構成とされている。なお、複数の電線13の結束状態は、結束バンド、粘着テープ等によって維持されている。なお、図2等では、分岐線12bの概形を示している。   The wire harness 12 is configured by bundling a plurality of electric wires 13. Here, the wire harness 12 is configured such that a plurality of electric wires 13 are bundled so that the branch line 12b branches from the intermediate portion in the extending direction of the main line 12a. The binding state of the plurality of electric wires 13 is maintained by a binding band, an adhesive tape, or the like. In FIG. 2 and the like, an outline of the branch line 12b is shown.

ワイヤーハーネス12の端部には、コネクタ14が接続されている。本ワイヤーハーネス12を含む配線モジュール10が車両に組込まれた状態で、各電線の端部に取付けられたコネクタ14が車両に搭載された各種電気部品に接続される。すなわち、本配線モジュール10は、車両に搭載される諸電気部品同士を接続する部品として用いられる。   A connector 14 is connected to the end of the wire harness 12. In a state where the wiring module 10 including the wire harness 12 is incorporated in the vehicle, the connector 14 attached to the end portion of each electric wire is connected to various electric components mounted on the vehicle. That is, this wiring module 10 is used as a component for connecting various electrical components mounted on the vehicle.

なお、本ワイヤーハーネス12には、光ファイバコード等が含まれていてもよい。また、プロテクタ20の収容対象となる配線部は、上記のように複数の電線13が束ねられたものに限られず、1本の電線のみによって構成されていてもよい。   The wire harness 12 may include an optical fiber cord or the like. Moreover, the wiring part used as the accommodation object of the protector 20 is not restricted to what the several electric wire 13 was bundled as mentioned above, and may be comprised only with one electric wire.

プロテクタ20は、プロテクタ本体部22と、複数(ここでは2つ)の突起部40とを含む。ここでは、プロテクタ本体部22と複数の突起部40とが、軟化した樹脂を射出成形金型に射出することによって製造された、金型一体成形部品として構成されている。もっとも、プロテクタ本体部と複数の突起部とが別々に成形され、複数の突起部がプロテクタ本体部に対して接着剤、粘着材、嵌め込み構造等によって取付けられてもよい。   The protector 20 includes a protector body 22 and a plurality of (here, two) protrusions 40. Here, the protector body 22 and the plurality of protrusions 40 are configured as a mold-integrated part manufactured by injecting a softened resin into an injection mold. However, the protector body and the plurality of protrusions may be separately formed, and the plurality of protrusions may be attached to the protector body by an adhesive, an adhesive, a fitting structure, or the like.

プロテクタ本体部22は、幹線収容部24と、分岐線収容部30とを含む。   The protector main body 22 includes a main line accommodating part 24 and a branch line accommodating part 30.

幹線収容部24は、幹線12aを収容する部分であり、底板部25と、一対の側板部26とを備える。底板部25は、細長板状に形成されている。一対の側板部26は、底板部25の両側部から立上がるように形成されている。そして、底板部25と一対の側板部26とで囲まれる空間内に、上記幹線12aの延在方向中間部を収容できる。   The trunk line accommodating part 24 is a part that accommodates the trunk line 12 a and includes a bottom plate part 25 and a pair of side plate parts 26. The bottom plate portion 25 is formed in an elongated plate shape. The pair of side plate portions 26 are formed so as to rise from both side portions of the bottom plate portion 25. And the intermediate direction part of the said trunk line 12a can be accommodated in the space enclosed by the baseplate part 25 and a pair of side-plate part 26. FIG.

また、一対の側板部26の一方の延在方向中間部に分岐用凹部27が形成されており、この部分に分岐線収容部30が設けられている。   Further, a branching concave portion 27 is formed in one extending direction intermediate portion of the pair of side plate portions 26, and a branch line accommodating portion 30 is provided in this portion.

分岐線収容部30は、底板部32と、一対の側板部34とを備える。   The branch line accommodating portion 30 includes a bottom plate portion 32 and a pair of side plate portions 34.

底板部32は、細長板状に形成され、底板部25の側縁部のうち上記分岐用凹部27が形成された部分から外方に延出するように形成されている。   The bottom plate portion 32 is formed in an elongated plate shape, and is formed so as to extend outward from a portion of the side edge portion of the bottom plate portion 25 where the branching concave portion 27 is formed.

一対の側板部34は、底板部32の両側部から立上がるように形成されている。一対の側板部34の一端部は、上記側板部26のうち分岐用凹部27が形成された縁部に連なっている。そして、幹線12aから分岐用凹部27の位置で分岐する分岐線12bを、底板部32と一対の側板部34とで囲まれる空間内に収容できる。なお、分岐線12bの先端部は分岐線収容部30から延出しているため、本分岐線収容部30は、配線部の延在方向中間部を収容している。   The pair of side plate portions 34 are formed so as to rise from both side portions of the bottom plate portion 32. One end portion of the pair of side plate portions 34 is connected to the edge portion of the side plate portion 26 where the branching concave portion 27 is formed. The branch line 12 b that branches off from the trunk line 12 a at the position of the branch recess 27 can be accommodated in a space surrounded by the bottom plate portion 32 and the pair of side plate portions 34. In addition, since the front-end | tip part of the branch line 12b is extended from the branch line accommodating part 30, this branch line accommodating part 30 accommodates the extension direction intermediate part of a wiring part.

分岐線12bは、分岐線収容部30の外側端部から延出している。そして、分岐線12bの端部のコネクタ14が電気部品18の相手側コネクタ19に接続される。   The branch line 12 b extends from the outer end of the branch line housing part 30. Then, the connector 14 at the end of the branch line 12 b is connected to the mating connector 19 of the electrical component 18.

なお、上記プロテクタ本体部22のうち底板部25、32の反対側開口が蓋部によって閉じられていてもよい。   In addition, the opening opposite to the bottom plate portions 25 and 32 in the protector main body portion 22 may be closed by a lid portion.

本配線モジュール10は、次のようにして車両に組込まれる。   The wiring module 10 is incorporated into a vehicle as follows.

すなわち、プロテクタ20が、車両に突設されたボルト、板状のブラケット、クランプ構造等を介して、車両の一定位置に固定される。また、分岐線12bのうち分岐線収容部30から延出する部分が、分岐線収容部30の先端部と車両に搭載された電気部品18との間に掛渡される。そして、分岐線12bの先端部のコネクタ14が車両に別途固定された電気部品18のコネクタ19に接続される。   That is, the protector 20 is fixed to a fixed position of the vehicle via a bolt, a plate-like bracket, a clamp structure, or the like that protrudes from the vehicle. Further, a portion of the branch line 12b that extends from the branch line housing portion 30 is spanned between the tip of the branch line housing portion 30 and the electrical component 18 mounted on the vehicle. And the connector 14 of the front-end | tip part of the branch line 12b is connected to the connector 19 of the electrical component 18 separately fixed to the vehicle.

ここで、プロテクタ20及び電気部品18は、それぞれ車両に固定されており、分岐線収容部30の先端部と電気部品18のコネクタ19に対するコネクタ14の接続箇所との距離が、寸法Lbであるとする(図4参照)。   Here, the protector 20 and the electrical component 18 are each fixed to the vehicle, and the distance between the tip of the branch line accommodating portion 30 and the connection portion of the connector 14 to the connector 19 of the electrical component 18 is the dimension Lb. (See FIG. 4).

これに対し、プロテクタ20に組込まれるワイヤーハーネス12は、通常、所定長の端子付電線を結束することにより構成される。通常、ワイヤーハーネス12を製造する際には、ある程度、誤差が発生する。このため、幹線12aを幹線収容部24内に収容するようにワイヤーハーネス12をプロテクタ20に組込んだ状態で、当該幹線12aから分岐する分岐線12bを分岐線収容部30内に収容すると、分岐線12bのうち分岐線収容部30から延出する部分の長さ寸法La(図1参照)はばらつく。   On the other hand, the wire harness 12 incorporated in the protector 20 is normally configured by binding a predetermined length of electric wire with a terminal. Usually, when manufacturing the wire harness 12, an error occurs to some extent. For this reason, if the branch line 12b branched from the trunk line 12a is accommodated in the branch line accommodating part 30 in a state where the wire harness 12 is incorporated in the protector 20 so as to accommodate the trunk line 12a in the trunk line accommodating part 24, the branch is generated. The length La (see FIG. 1) of the portion of the line 12b extending from the branch line accommodating portion 30 varies.

そして、寸法Laが寸法Lbよりも大きいと、分岐線収容部30の先端部と電気部品18との間で、分岐線12bが弛んでしまう(図4において2点鎖線で示す分岐線12b参照)。とすると、分岐線12bがその周辺部分に干渉し、異音の発生或は摩擦による劣化等を生じる恐れがある。   And if the dimension La is larger than the dimension Lb, the branch line 12b will loosen between the front-end | tip part of the branch line accommodating part 30, and the electric component 18 (refer the branch line 12b shown with a dashed-two dotted line in FIG. 4). . Then, the branch line 12b may interfere with the peripheral portion thereof, which may cause abnormal noise or deterioration due to friction.

ここで、仮に、分岐線12bの余長部分を分岐線収容部30内に収めたとしても、当該余長部分が分岐線収容部30内で弛んだままであると、同様に、分岐線12bの余長部分が分岐線収容部30内面に干渉し、異音の発生或は摩擦による劣化等を生じる恐れがある。   Here, even if the surplus part of the branch line 12b is accommodated in the branch line accommodating part 30, if the surplus part remains loose in the branch line accommodating part 30, the branch line 12b The surplus portion may interfere with the inner surface of the branch line accommodating portion 30 and may cause abnormal noise or deterioration due to friction.

そこで、次に説明する複数の突起部40と結束部材50とを用いた構成によって、分岐線12bの余長部分を、弛みを抑制しつつ吸収するようにしている。   Therefore, the configuration using the plurality of protrusions 40 and the bundling member 50 described below absorbs the extra length of the branch line 12b while suppressing slack.

すなわち、プロテクタ本体部22の内周部に、分岐線12bの延在方向に沿って間隔をあけて複数の突起部40が設けられている。   That is, a plurality of protrusions 40 are provided on the inner peripheral portion of the protector main body 22 at intervals along the extending direction of the branch line 12b.

ここでは、突起部40が2つ設けられた例を説明するが、突起部が3つ以上設けられ、各間において後述するように結束部材50が分岐線12bに巻付けられていてもよい。   Here, an example in which two protrusions 40 are provided will be described. However, three or more protrusions may be provided, and the binding member 50 may be wound around the branch line 12b between each as described later.

より具体的には、2つの突起部40は、一方の側板部34から他方の側板部34に向けて突出するように設けられている。   More specifically, the two protruding portions 40 are provided so as to protrude from one side plate portion 34 toward the other side plate portion 34.

突起部40は、方形板状に形成されている。突起部40の幅方向寸法(分岐線収容部30の深さ方向の寸法)は、分岐線収容部30の深さ寸法と同じであり、突起部40の突出寸法(一対の側板部34を結ぶ方向の寸法)は、一対の側板部34間の内面間の寸法から分岐線12bの外径寸法を減算した寸法よりも小さく設定されている。ここでは、突起部40の突出寸法は、一対の側板部34間の内面間の寸法の半分を超える寸法に設定されている。   The protrusion 40 is formed in a square plate shape. The width direction dimension of the projection 40 (the dimension in the depth direction of the branch line accommodation part 30) is the same as the depth dimension of the branch line accommodation part 30, and the projection dimension of the projection 40 (the pair of side plate parts 34 is connected). The dimension in the direction) is set smaller than the dimension obtained by subtracting the outer diameter dimension of the branch line 12b from the dimension between the inner surfaces between the pair of side plate portions 34. Here, the protruding dimension of the protrusion 40 is set to a dimension that exceeds half of the dimension between the inner surfaces of the pair of side plate portions 34.

突起部40の基端部は、一方の側板部34に一体化されており、突起部40の一方の側部は、底板部32に一体化されている。また、突起部40の先端部40aは、先端側に向けて凸となるように湾曲する形状に形成されている。   The base end portion of the protruding portion 40 is integrated with one side plate portion 34, and one side portion of the protruding portion 40 is integrated with the bottom plate portion 32. The tip 40a of the protrusion 40 is formed in a curved shape so as to be convex toward the tip.

2つの突起部40は、配線部である分岐線12bの延在方向に沿って間隔をあけて配設されている。2つの突起部40間の寸法は、分岐線12bを曲げて配設可能な程度の大きさに設定されている。   The two protrusions 40 are arranged at intervals along the extending direction of the branch line 12b which is a wiring part. The dimension between the two protrusions 40 is set to such a size that the branch line 12b can be bent and disposed.

また、プロテクタ本体部22のうち2つの突起部40間の部分に、結束部材通し孔38が形成されている。ここでは、結束部材通し孔38は、底板部32に形成されている。結束部材通し孔38は、後述する結束部材50のバンド部54の幅より大きい幅のスリット状の孔であり、2つの突起部40の先端部40aを結ぶラインを横切るように、底板部32の幅方向に沿って細長く形成されている。従って、バンド部54は、突起部40の突出方向において位置を調整しつつ、底板部32を通ることができる。   A bundling member through hole 38 is formed in a portion between the two protrusions 40 in the protector body 22. Here, the bundling member through hole 38 is formed in the bottom plate portion 32. The binding member through hole 38 is a slit-like hole having a width larger than the width of the band portion 54 of the binding member 50 described later, and the bottom plate portion 32 of the bottom plate portion 32 crosses the line connecting the tip portions 40a of the two protrusions 40. It is formed elongated along the width direction. Accordingly, the band portion 54 can pass through the bottom plate portion 32 while adjusting the position in the protruding direction of the protruding portion 40.

なお、上記2つの突起部及び結束部材通し孔38の各部の好ましい寸法の一例は次の通りである。まず、突起部40の突出寸法Aは、収容対象となる分岐線12bの外径に3〜5mmを付加した値とすることが好ましい。また、2つの突起部40の厚み方向中央部分間の寸法Dは30mm以上とすることが好ましい。   In addition, an example of the preferable dimension of each part of said 2 protrusion part and binding member through-hole 38 is as follows. First, the protrusion dimension A of the protrusion 40 is preferably a value obtained by adding 3 to 5 mm to the outer diameter of the branch line 12b to be accommodated. Moreover, it is preferable that the dimension D between the thickness direction center parts of the two projection parts 40 shall be 30 mm or more.

より具体的には、この場合、突起部40の突出方向において、突起部40と結束部材通し孔38とが重複する寸法Bは3〜5mm、突起部40のうち結束部材通し孔38と重複しない部分の寸法Cは分岐線12bの外径と同じとすることが好ましい。また、2つの突起部40の厚み方向中央部分間の寸法Dは30mm、結束部材通し孔38の幅寸法Eは5mmとすることが好ましい。もっとも、上記各寸法は、想定される余長吸収量、配線部の外径等に応じて、適宜変更される。   More specifically, in this case, in the protruding direction of the protrusion 40, the dimension B where the protrusion 40 and the binding member through hole 38 overlap is 3 to 5 mm, and the protrusion 40 does not overlap with the binding member through hole 38. The dimension C of the part is preferably the same as the outer diameter of the branch line 12b. Moreover, it is preferable that the dimension D between the thickness direction center part of the two projection parts 40 is 30 mm, and the width dimension E of the bundling member through hole 38 is 5 mm. However, each of the above dimensions is appropriately changed according to an assumed surplus absorption amount, an outer diameter of the wiring portion, and the like.

結束部材50自体は、一般的に、結束バンド、結束タイ等と呼ばれる部品である。すなわち、結束部材50は、軟質樹脂等により一体形成された部品であり、バンド固定部52と、バンド部54とを備える。   The binding member 50 itself is generally a part called a binding band, a binding tie or the like. That is, the binding member 50 is a part integrally formed of a soft resin or the like, and includes a band fixing part 52 and a band part 54.

バンド部54は、一方主面に複数の係止溝が形成された帯状部分とされている。バンド固定部52は、バンド部54を挿通可能な角筒形状に形成されると共に、その内部に前記複数の係止溝に選択的に係止可能な係止爪が形成された構成とされている。そして、バンド部54をバンド固定部52に挿通して、バンド部54の先端部を引っ張っていくと、係止爪がバンド部54の延在方向の任意の位置で係止溝に一方向に係止した状態に保持され、これにより、結束部材50が所定の周長の環状をなした状態に維持されるようになっている。   The band portion 54 is a band-shaped portion in which a plurality of locking grooves are formed on one main surface. The band fixing portion 52 is formed in a rectangular tube shape through which the band portion 54 can be inserted, and a locking claw that can be selectively locked in the plurality of locking grooves is formed therein. Yes. Then, when the band portion 54 is inserted into the band fixing portion 52 and the tip end portion of the band portion 54 is pulled, the locking claw is in one direction in the locking groove at an arbitrary position in the extending direction of the band portion 54. Thus, the binding member 50 is maintained in an annular shape having a predetermined circumferential length.

なお、結束部材としては、上記のような結束バンドの他、粘着テープ等を用いてもよい。   In addition, as a binding member, you may use an adhesive tape other than the above binding bands.

結束部材50は、2つの突起部40の間で、分岐線12bを突起部40の基端側に向けて引っ張るように、プロテクタ本体部22の一部及び分岐線12bに巻付けられている。   The binding member 50 is wound around a part of the protector main body 22 and the branch line 12b so as to pull the branch line 12b toward the proximal end side of the protrusion 40 between the two protrusions 40.

より具体的には、結束部材50のバンド部54が結束部材通し孔38を通って分岐線収容部30の底板部32外方から内方に向けて導かれる。さらに、バンド部54は、突起部40の先端部に対向する側板部34と分岐線12bとの間を通って、分岐線収容部30の上方開口に導かれる。そして、バンド部54がバンド部54に挿通されている。この状態で、結束部材50の周長が短くなるように締付けられて、2つの突起部40の間で、分岐線12bが突起部40の基端側に向けて引っ張られている。この状態で、分岐線12bは、2つの突起部40の間でその基端側に向けてV字状に曲げられる。この曲げの状態に応じて、分岐線12bの余長が吸収されている。   More specifically, the band portion 54 of the binding member 50 is guided from the outside of the bottom plate portion 32 of the branch line accommodating portion 30 to the inside through the binding member through hole 38. Further, the band portion 54 is guided to the upper opening of the branch line accommodation portion 30 through the space between the side plate portion 34 facing the tip end portion of the projection portion 40 and the branch line 12b. The band unit 54 is inserted through the band unit 54. In this state, the binding member 50 is tightened so that the peripheral length is shortened, and the branch line 12 b is pulled toward the base end side of the protrusion 40 between the two protrusions 40. In this state, the branch line 12b is bent in a V shape between the two protrusions 40 toward the base end side. The extra length of the branch line 12b is absorbed according to the bending state.

上記配線モジュール10の製造方法について説明する。   A method for manufacturing the wiring module 10 will be described.

まず、図5に示すように、配線部の延在方向中間部である分岐線12bを、プロテクタ本体部22内に収容する。そして、分岐線12bを、プロテクタ本体部22内であって2つの突起部40の先端部側を通過するように配設する。   First, as shown in FIG. 5, the branch line 12 b which is an intermediate portion in the extending direction of the wiring portion is accommodated in the protector main body portion 22. And the branch line 12b is arrange | positioned so that the front-end | tip part side of the two projection parts 40 may pass in the protector main-body part 22. FIG.

この後、図6に示すように、結束部材50のバンド部54を結束部材通し孔38に通し、分岐線収容部30のうち結束部材通し孔38の一側外方部分及び分岐線12bの周りに配設する。そして、バンド部54の先端部をバンド固定部52に通し、2つの突起部40の間で、分岐線12bを突起部40の基端側に向けて引っ張るように、結束部材50を締付けて、結束部材50を、分岐線収容部30のうち結束部材通し孔38の一側外方部分及び分岐線12bに巻回する。   Thereafter, as shown in FIG. 6, the band portion 54 of the binding member 50 is passed through the binding member through hole 38, and one side outward portion of the binding member through hole 38 in the branch line accommodating portion 30 and around the branch line 12 b. It arranges in. Then, the band member 54 is passed through the band fixing portion 52, and the binding member 50 is tightened so that the branch line 12b is pulled toward the base end side of the protrusion 40 between the two protrusions 40. The binding member 50 is wound around the branch wire 12b on one side of the branch line accommodation portion 30 and the branch line 12b.

この際、分岐線12bのうち分岐線収容部30から延出する部分の長さ寸法Laが、分岐線収容部30と電気部品18との距離に応じた寸法Lbとなるように、バンド部54の締付け量、即ち、2つの突起部40の間での分岐線12bの曲げ程度を調整する。従って、2つの突起部40の間での分岐線12bの曲げ程度は、図1と図7とに示すように、異なる場合があり得る。図1では、分岐線12bの余長が比較的大きく、従って、2つの突起部40の間で分岐線12bが比較的大きく曲げられた場合を示しており、図7では、分岐線12bの余長が比較的小さく、従って、2つの突起部40の間で分岐線12bが比較的小さく曲げられた場合を示している。   At this time, the band portion 54 is set so that the length dimension La of the portion extending from the branch line accommodating portion 30 in the branch line 12b becomes a dimension Lb corresponding to the distance between the branch line accommodating portion 30 and the electrical component 18. The amount of tightening, that is, the degree of bending of the branch line 12b between the two protrusions 40 is adjusted. Therefore, the bending degree of the branch line 12b between the two protrusions 40 may be different as shown in FIG. 1 and FIG. 1 shows a case where the extra length of the branch line 12b is relatively large, and therefore, the branch line 12b is bent relatively large between the two protrusions 40. In FIG. 7, the extra line of the branch line 12b is shown. This shows a case where the length is relatively small, and therefore the branch line 12b is bent relatively small between the two protrusions 40.

これにより、配線モジュール10が完成する。   Thereby, the wiring module 10 is completed.

以上のように構成された配線モジュール10、プロテクタ20及び配線モジュールの製造方法によると、複数の突起部40の間で分岐線12bを突起部40の基端側に向けて引っ張るように、結束部材50がプロテクタ本体部22の分岐線12bの一部及び配線部である分岐線12bに巻付けられている。このため、分岐線12bのうち分岐線収容部30から延出する部分の余長を、その余長量に応じて前記引っ張り量を調整して分岐線12bの曲げ程度を調整して、当該余長をより確実に吸収できる。   According to the wiring module 10, the protector 20, and the method for manufacturing the wiring module configured as described above, the bundling member is configured to pull the branch line 12 b toward the base end side of the protrusion 40 between the plurality of protrusions 40. 50 is wound around a part of the branch line 12b of the protector body 22 and the branch line 12b which is a wiring part. For this reason, the surplus length of the branch line 12b extending from the branch line accommodating portion 30 is adjusted according to the amount of the surplus length to adjust the degree of bending of the branch line 12b. The length can be absorbed more reliably.

また、分岐線12bの余長はプロテクタ20内で吸収され、複数の突起部40の間では、分岐線12bが突起部40の基端側に向けて引っ張られているため、分岐線12bの自由な動きが抑制され、分岐線収容部30内での分岐線12bと分岐線収容部30の内面との間での異音の発生及び他の部分との干渉を有効に抑制できる。   Further, the extra length of the branch line 12b is absorbed in the protector 20, and the branch line 12b is pulled toward the base end side of the protrusion 40 between the plurality of protrusions 40. Therefore, the generation of abnormal noise between the branch line 12b and the inner surface of the branch line accommodating portion 30 in the branch line accommodating portion 30 and the interference with other portions can be effectively suppressed.

また、分岐線12bは、結束部材50により引っ張られ、複数の突起部40の先端部40aに押付けられた状態となっているため、分岐線12bはその延在方向において移動し難い。このため、分岐線収容部30からの分岐線12bの延出量を一定に保つことができ、本配線モジュール10を車両に組付ける際に、分岐線12bが引っ張られたとしても、分岐線12bのうち分岐線収容部30から延出する部分の長さ寸法をより確実に一定に保つことができる。   Further, since the branch line 12b is pulled by the binding member 50 and pressed against the distal end portions 40a of the plurality of protrusions 40, the branch line 12b is difficult to move in the extending direction. For this reason, the extension amount of the branch line 12b from the branch line accommodating part 30 can be kept constant, and even when the branch line 12b is pulled when the wiring module 10 is assembled to the vehicle, the branch line 12b Of these, the length dimension of the portion extending from the branch line accommodating portion 30 can be more reliably kept constant.

また、結束部材50を、結束部材通し孔38に通しつつ、分岐線収容部30の一部及び分岐線12bに巻付けることができるため、分岐線12bの3方を囲うような分岐線収容部30においても、余長吸収を行うことができ、分岐線12bを分岐線収容部30内により完全に収容することができる。   Moreover, since the binding member 50 can be wound around a part of the branch line accommodation part 30 and the branch line 12b while passing through the binding member through hole 38, the branch line accommodation part that surrounds the three sides of the branch line 12b. Also in 30, the extra length can be absorbed, and the branch line 12b can be completely accommodated in the branch line accommodating part 30.

もっとも、プロテクタ本体部が分岐線12bの3方を覆っていることは必須ではなく、2方又は1方向から覆う構成であってもよい。この場合には、プロテクタを構成する底板部又は側板部の幅等によっては、結束部材通し孔を設けなくてもよい。   But it is not essential that the protector main-body part has covered 3 directions of the branch line 12b, and the structure which covers from 2 directions or 1 direction may be sufficient. In this case, the bundling member through hole may not be provided depending on the width of the bottom plate portion or the side plate portion constituting the protector.

また、プロテクタ本体部22と突起部40とが一体形成されているため、プロテクタ20を低コストで製造できる。   Moreover, since the protector main-body part 22 and the projection part 40 are integrally formed, the protector 20 can be manufactured at low cost.

また、突起部40の先端部40aが先端側に向けて湾曲する形状に形成されているため、分岐線12bと突起部40との接触による、分岐線12bのダメージを抑制できる。   Moreover, since the front-end | tip part 40a of the projection part 40 is formed in the shape which curves toward a front end side, the damage of the branch line 12b by the contact with the branch line 12b and the projection part 40 can be suppressed.
