Description

車載電線用の結束具およびワイヤハーネスFasteners and wire harnesses for in-vehicle electric wires
　本発明は、車載電線用の結束具およびワイヤハーネスに関する。 BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a binder and a wire harness for an in-vehicle electric wire.
　特許文献１には、バンドクリップが記載されている。このバンドクリップはワイヤハーネスを結束する。具体的には、バンドクリップはバンド部と固縛部挿通係止部と車両取付部とを備えている。バンド部は帯状の形状を有しており、ワイヤハーネスに巻き付けられる。固縛部挿通係止部はバンド部の基端に設けられており、バンド部を先端側から貫通させて係止する。これにより、バンド部は環状に保持されて、ワイヤハーネスを固縛する。車両取付部は固縛部挿通係止部に固設されており、車両の固定パネルに固定される。これにより、ワイヤハーネスを車両に固定することができる。 Patent Document 1 describes a band clip. This band clip ties the wire harness. Specifically, the band clip includes a band portion, a securing portion insertion locking portion, and a vehicle attachment portion. The band portion has a band-like shape and is wound around the wire harness. The fastening portion insertion locking portion is provided at the base end of the band portion, and the band portion is penetrated from the distal end side and locked. Thus, the band portion is held in an annular shape to fasten the wire harness. The vehicle attachment portion is fixed to the fastening portion insertion locking portion, and is fixed to a fixed panel of the vehicle. Thereby, the wire harness can be fixed to the vehicle.
特開２００９－２４３５２６号公報JP, 2009-243526, A
　バンド部を挿通係止部に挿通させると、バンド部はその先端側において挿通係止部から突出する。このように挿通係止部から突出したバンド部（余剰部分）は、ワイヤハーネスから遠ざかる方向に延在し得る。この場合、余剰部分は他の部材に干渉（衝突）しやすく、作業の邪魔になり得る。よって従来ではこの余剰部分を切断する場合がある。 When the band portion is inserted through the insertion locking portion, the band portion protrudes from the insertion locking portion on the tip end side. Thus, the band part (surplus part) which protruded from the penetration locking part can extend in the direction away from a wire harness. In this case, the surplus portion easily interferes (collisions) with other members, which can be an obstacle to work. Therefore, in the prior art, this surplus portion may be cut off.
　例えば作業員がワイヤハーネスをハーネス図版に取り付けた上で、バンドクリップを取り付け、その後、余剰部分を切断する。このとき、余剰部分を切断する道具（治具）がハーネス図版と干渉して、作業が困難になる場合があった。 For example, a worker attaches a wire harness to a harness plate, attaches a band clip, and then cuts an excess portion. At this time, a tool (jig) for cutting the surplus portion may interfere with the harness illustration, making the operation difficult.
　そこで、本発明は、余剰部分が電線から離れにくい車載電線用の結束具を提供することを目的とする。 Then, an object of this invention is to provide the binding tool for vehicle-mounted electric wires which an excessive part can not separate easily from an electric wire.
　車載電線用の結束具は車両に搭載される電線に巻回される。この結束具はバンド部とヘッド部とバンドループ部とを備える。バンド部は先端と基端とを有して帯状に形成されている。ヘッド部は基端に設けられており、バンド部を環状に保持するときにバンド部によって貫通される。バンドループ部は取付部と第１貫通孔とを有する。取付部は基端よりも先端に近い位置でバンド部に取り付けられる。第１貫通孔には、バンド部を環状に保持するときにバンド部のうちでヘッド部を貫通する位置よりも先端に近い部分によって貫通される。 The binding for the in-vehicle electric wire is wound around the electric wire mounted on the vehicle. The tie includes a band, a head and a band loop. The band portion is formed in a band shape having a distal end and a proximal end. The head portion is provided at the proximal end and is penetrated by the band portion when the band portion is held in an annular shape. The band loop portion has a mounting portion and a first through hole. The attachment portion is attached to the band portion at a position closer to the distal end than the proximal end. When the band portion is held in an annular shape, the first through hole is penetrated by a portion of the band portion that is closer to the tip than the position that penetrates the head portion.
　車載電線用の結束具によれば、余剰部分（外周側バンド部）が電線から離れにくい。 According to the binding for the in-vehicle electric wire, the surplus portion (the outer peripheral side band portion) does not easily separate from the electric wire.

　第１の実施の形態．
　図１および図２は、結束具１０の構成の一例を概略的に示す平面図である。図１および図２では、互いに反対方向から見たときの結束具１０が示されている。図３は、結束具１０および電線９０の構成の一例を概略的に示す図である。以下では、結束具１０および電線９０を纏めてワイヤハーネスとも呼ぶ。 First Embodiment
FIG. 1 and FIG. 2 are plan views schematically showing an example of the configuration of the binding 10. 1 and 2 show the closure 10 when viewed from opposite directions. FIG. 3 is a view schematically showing an example of the configuration of the binding 10 and the electric wire 90. As shown in FIG. Hereinafter, the binding tool 10 and the electric wire 90 are collectively referred to as a wire harness.
　＜電線＞
　電線９０は１本の電線であってもよく、或いは複数本の電線（電線束）であってもよい。図３の例示では、電線９０の延在方向から見た構成を、電線９０についてはその断面を模式的に円で示している。この電線９０は、自動車などの車両に用いられる電線（車載電線）であり、車両内において配索される。電線９０は、車両内に搭載された複数の電子装置を電気的に接続する。 <Wire>
The wire 90 may be a single wire or a plurality of wires (wire bundle). In the example of FIG. 3, the configuration as viewed from the extending direction of the electric wire 90 is schematically shown by a circle for the cross section of the electric wire 90. The electric wire 90 is an electric wire (on-vehicle electric wire) used for a vehicle such as a car, and is wired in the vehicle. The electric wire 90 electrically connects a plurality of electronic devices mounted in the vehicle.
　＜結束具＞
　図１から図３の例示では、結束具１０は例えば配線用合成樹脂結束帯であり、留め具付結束具、あるいはバンド付クランプと称される場合もある。但しその材料は必ずしも合成樹脂には限定されない。この結束具１０は留め具部１と結束基部３とを備えている。留め具部１は結束基部３に固定されている。結束基部３は後に詳述するように電線９０に巻き付く部材である。結束基部３が電線９０に巻き付くことにより、留め具部１を電線９０に固定することができる。また電線９０が複数本の電線である場合には、結束基部３はこれら複数本の電線を束ねることができる。この場合、結束基部３は複数本の電線を結束する。留め具部１は、ワイヤハーネスを車体に取り付けるための部材である。留め具部１は例えば車体に形成される孔を貫通し、当該孔を形成する縁に係止する。これにより、ワイヤハーネスが車体に固定される。 <Tie>
In the illustration of FIGS. 1 to 3, the binding 10 is, for example, a synthetic resin binding band for wiring, and may be referred to as a binding with fastening or a clamp with a band. However, the material is not necessarily limited to the synthetic resin. The binding device 10 includes a fastening portion 1 and a binding base 3. The fastener portion 1 is fixed to the binding base 3. The binding base 3 is a member wound around the electric wire 90 as described in detail later. The binding portion 3 can be fixed to the wire 90 by winding the binding base 3 around the wire 90. When the electric wire 90 is a plurality of electric wires, the binding base 3 can bundle the plurality of electric wires. In this case, the binding base 3 binds a plurality of electric wires. The fastener portion 1 is a member for attaching the wire harness to a vehicle body. The fastener portion 1 penetrates, for example, a hole formed in the vehicle body and locks to an edge forming the hole. Thereby, the wire harness is fixed to the vehicle body.
　＜結束基部＞
　結束基部３はバンド部４とヘッド部５とバンドループ部６とを備えている。バンド部４は、長手方向に延在する帯状の形状を有している（図１および図２参照）。以下では、長手方向におけるバンド部４の両端をそれぞれ先端４ａおよび基端４ｂと呼ぶ。バンド部４は弾性変形可能であり、少なくともバンド部４の主面に垂直な方向（紙面垂直な方向）においてバンド部４を曲げることができる。バンド部４の一方の主面（図１において現れる側の主面）には、長手方向に沿って複数の凸部４１が設けられる。換言すれば、これらの複数の凸部４１の相互間には凹部４２が形成されることになる。 <Cohesive base>
The binding base 3 includes a band 4, a head 5 and a band loop 6. The band 4 has a strip shape extending in the longitudinal direction (see FIGS. 1 and 2). Hereinafter, both ends of the band 4 in the longitudinal direction will be referred to as a tip 4a and a base 4b, respectively. The band portion 4 is elastically deformable, and can bend the band portion 4 at least in the direction perpendicular to the main surface of the band portion 4 (the direction perpendicular to the paper surface). On one main surface (the main surface on the side which appears in FIG. 1) of the band portion 4, a plurality of convex portions 41 are provided along the longitudinal direction. In other words, the recess 42 is formed between the plurality of projections 41.
　ヘッド部５は、先端４ａからバンド部４によって貫通されて、バンド部４を環状に保持するための部材であり、バンド部４の基端４ｂに設けられている。図１から図３の例示では、ヘッド部５は留め具部１にも固定されている。留め具部１、バンド部４およびヘッド部５は例えば合成樹脂によって一体に形成されてもよい。つまり留め具部１、バンド部４およびヘッド部５の一組は一体成形部材であってもよい。 The head portion 5 is a member which is penetrated from the tip 4 a by the band portion 4 and holds the band portion 4 in an annular shape, and is provided at the base end 4 b of the band portion 4. In the illustration of FIGS. 1 to 3 the head part 5 is also fixed to the fastener part 1. The fastener portion 1, the band portion 4 and the head portion 5 may be integrally formed of, for example, a synthetic resin. That is, one set of the fastener portion 1, the band portion 4 and the head portion 5 may be an integrally formed member.
　ヘッド部５は枠体５２と係止部５３とを有している。この枠体５２には貫通孔５１が貫通している。例えば枠体５２は環状に形成されて貫通孔５１を囲む。あるいは枠体５２は環状の一部が開口した形状（例えばコの字型、Ｕ字型）を呈してもよい。バンド部４はその先端４ａからこの貫通孔５１に通される。このようにバンド部４が貫通孔５１を通ることによって、バンド部４は環状を呈する（図３参照）。なお図３では図面の煩雑を避けるため、係止部５３を省略している。バンド部４が環状を呈するときには、バンド部４の長手方向が環状についての周方向となり、バンド部４の主面に垂直な方向が環状についての径方向となる。貫通孔５１は周方向に沿って枠体５２を貫通しており、バンド部４は周方向に沿って貫通孔５１を貫通する。以下では、この環状についての内周側および外周側を導入して説明を行う。 The head portion 5 has a frame 52 and a locking portion 53. A through hole 51 passes through the frame 52. For example, the frame 52 is annularly formed to surround the through hole 51. Alternatively, the frame 52 may have a partially open annular shape (for example, a U-shape or a U-shape). The band 4 is passed through the through hole 51 from its tip 4a. By the band 4 passing through the through holes 51 in this manner, the band 4 exhibits an annular shape (see FIG. 3). In addition, in FIG. 3, in order to avoid the complication of drawing, the latching | locking part 53 is abbreviate | omitted. When the band 4 has an annular shape, the longitudinal direction of the band 4 is the circumferential direction of the annular, and the direction perpendicular to the main surface of the band 4 is the radial direction of the annular. The through hole 51 penetrates the frame 52 along the circumferential direction, and the band portion 4 penetrates the through hole 51 along the circumferential direction. The following description will be made by introducing the inner and outer circumferential sides of the ring.
　係止部５３は、枠体５２のうち内周側の部分に設けられ、貫通孔５１に向かって（外周側へと）突出している。この場合にはバンド部４は、凸部４１内周側に向けた姿勢で、枠体５２を貫通する。これにより、貫通孔５１において係止部５３はバンド部４の凹部４２に嵌って凸部４１の少なくとも一つと係止する。貫通孔５１はバンド部４が貫通することを許す程度に広いが、径方向においてバンド部４が大きく移動できるほどには広くない。よってこの係止によって、バンド部４がヘッド部５から抜けることを阻害する。これにより、バンド部４が環状に保持される。 The locking portion 53 is provided at a portion on the inner circumferential side of the frame 52 and protrudes toward the through hole 51 (to the outer circumferential side). In this case, the band 4 penetrates the frame 52 in a posture directed to the inner peripheral side of the convex portion 41. As a result, in the through hole 51, the locking portion 53 is fitted into the recess 42 of the band 4 and locked with at least one of the protrusions 41. The through hole 51 is wide enough to allow the band 4 to penetrate, but not wide enough to allow the band 4 to move largely in the radial direction. Therefore, the locking prevents the band 4 from coming off the head 5. Thereby, the band part 4 is hold | maintained cyclically.
　このようにバンド部４が環状に保持された状態において、基端４ｂからヘッド部５までのバンド部４を、以下では、内周側バンド部４３とも呼ぶ。またヘッド部５から先端４ａまでのバンド部４を外周側バンド部４４とも呼ぶ。内周側バンド部４３は、径方向において外周側バンド部４４と重なる周方向の位置においては、外周側バンド部４４よりも内周側（図３では電線９０側）に位置する。 As described above, in the state where the band portion 4 is held in an annular shape, the band portion 4 from the base end 4 b to the head portion 5 is hereinafter also referred to as an inner circumferential side band portion 43. The band 4 from the head 5 to the tip 4 a is also referred to as an outer peripheral band 44. The inner circumferential side band portion 43 is positioned on the inner circumferential side (the wire 90 side in FIG. 3) of the outer circumferential side band portion 44 at a circumferential position overlapping the outer circumferential side band portion 44 in the radial direction.
　図１から図３に示すように、バンドループ部６は、内周側バンド部４３においてバンド部４に取り付けられる。またバンドループ部６はバンド部４が環状に保持された状態において、外周側バンド部４４によって貫通される（図３参照）。外周側バンド部４４は、バンド部４の巻回方向Ｄ１に沿って、その先端４ａからバンドループ部６に挿入される。この巻回方向Ｄ１は周方向についての一方向であり、図３の例示では反時計回りである。 As shown in FIGS. 1 to 3, the band loop portion 6 is attached to the band portion 4 at the inner circumferential side band portion 43. Moreover, the band loop part 6 is penetrated by the outer peripheral side band part 44 in the state by which the band part 4 was hold | maintained cyclically (refer FIG. 3). The outer circumferential side band portion 44 is inserted into the band loop portion 6 from the tip 4 a along the winding direction D 1 of the band portion 4. The winding direction D1 is one direction in the circumferential direction, and is counterclockwise in the example of FIG.
　図４はバンドループ部６の構成の一例を概略的に示す図である。図４では、周方向に沿って見たバンドループ部６が示されている。図５は、図４のＶ－Ｖ断面矢視図を概略的に示している。なお図５では、図４では省略されたバンド部４も追加して示されている。図４および図５に示すように、バンドループ部６はバンド部４に取り付けられる。またバンドループ部６はバンド部４を環状に保持するときに、バンド部４のうちでヘッド部５を貫通する位置よりも先端４ａに近い部分によって貫通される。またバンドループ部６はバンド部４によるバンドループ部６から抜ける方向の移動を阻害する。具体的には例えば、バンドループ部６は本体部６３と係止部６５とを有し、後述するように係止部６５が上記移動の阻害に寄与する。バンドループ部６は例えば合成樹脂の一体成形部材であってもよい。 FIG. 4 is a diagram schematically showing an example of the configuration of the band loop unit 6. In FIG. 4, the band loop part 6 seen along the circumferential direction is shown. FIG. 5 schematically shows a VV cross-sectional arrow view of FIG. In FIG. 5, the band portion 4 omitted in FIG. 4 is additionally shown. As shown in FIGS. 4 and 5, the band loop portion 6 is attached to the band portion 4. Further, when the band loop portion 6 holds the band portion 4 in an annular shape, the band loop portion 6 is penetrated by a portion closer to the tip 4 a than the position of penetrating the head portion 5 in the band portion 4. Further, the band loop unit 6 inhibits the movement of the band unit 4 in the direction of coming out of the band loop unit 6. Specifically, for example, the band loop portion 6 has a main body portion 63 and a locking portion 65, and the locking portion 65 contributes to the inhibition of the movement as described later. The band loop portion 6 may be, for example, an integrally molded member of synthetic resin.
　本体部６３には、貫通孔６１および貫通孔６２が形成されている。貫通孔６１，６２はいずれも周方向に沿って本体部６３を貫通する（図３も参照）。なお図３では図面の煩雑を避けるため、係止部６５を省略している。また貫通孔６１，６２は径方向において隣り合う位置に形成される。貫通孔６１は貫通孔６２よりも内周側に位置している。内周側バンド部４３は貫通孔６１を周方向に沿って貫通し、外周側バンド部４４は貫通孔６２を周方向に沿って貫通する。 A through hole 61 and a through hole 62 are formed in the main body portion 63. The through holes 61 and 62 both penetrate the main body 63 along the circumferential direction (see also FIG. 3). In addition, in FIG. 3, in order to avoid the complication of drawing, the latching | locking part 65 is abbreviate | omitted. Further, the through holes 61 and 62 are formed adjacent to each other in the radial direction. The through hole 61 is located on the inner peripheral side of the through hole 62. The inner circumferential side band portion 43 penetrates the through hole 61 along the circumferential direction, and the outer circumferential side band portion 44 penetrates the through hole 62 along the circumferential direction.
　図４の例示では、貫通孔６１は内周側（紙面上方）にも開口している。例えば本体部６３は、外周部６３１と一対の内周部６３２と仕切り部６３３と側面部６３４，６３５とを備えている。側面部６３４，６３５はバンド部４の幅方向において互いに対面しており、内周側において貫通孔６１を介して互いに対面する。一対の内周部６３２は、それぞれ側面部６３４，６３５の内周側の端から互いに近づくように延在している。この一対の内周部６３２は径方向において貫通孔６１を介して仕切り部６３３と対面する。仕切り部６３３は貫通孔６１，６２を隔てる部分であり、その上記幅方向における両端が側面部６３４，６３５に連結される。 In the example of FIG. 4, the through hole 61 is also opened to the inner peripheral side (upper side in the drawing). For example, the main body portion 63 includes an outer peripheral portion 631, a pair of inner peripheral portions 632, partition portions 633, and side surface portions 634 and 635. The side surface portions 634 and 635 face each other in the width direction of the band portion 4 and face each other via the through holes 61 on the inner peripheral side. The pair of inner peripheral portions 632 extend from the inner peripheral ends of the side surface portions 634 and 635 so as to approach each other. The pair of inner circumferential portions 632 face the partition portion 633 via the through holes 61 in the radial direction. The partition portion 633 is a portion that separates the through holes 61 and 62, and both ends in the width direction are connected to the side surface portions 634 and 635.
　なお貫通孔６１の周りの側面部６３４，６３５と、仕切り部６３３とからなる部分を連結部と呼ぶと、この連結部を次のように説明することもできる。即ち、連結部は、一対の内周部６３２に連なって、外周側からバンド部４（内周側バンド部４３）を囲む。つまり連結部は、バンド部４に対して一対の内周部６３２とは反対側において、一対の内周部６３２を連結する。図４の例示では、一対の内周部６３２は互いに離間しており、貫通孔６１は一対の内周部６３２の間において内周側に開口することになる。 When the portion including the side surface portions 634 and 635 around the through hole 61 and the partition portion 633 is referred to as a connecting portion, the connecting portion can also be described as follows. That is, the connecting portion is connected to the pair of inner circumferential portions 632 and surrounds the band portion 4 (the inner circumferential side band portion 43) from the outer circumferential side. That is, the connecting portion connects the pair of inner circumferential portions 632 on the side opposite to the pair of inner circumferential portions 632 with respect to the band portion 4. In the example of FIG. 4, the pair of inner circumferential portions 632 are separated from each other, and the through hole 61 opens to the inner circumferential side between the pair of inner circumferential portions 632.
　バンド部４（内周側バンド部４３）がこの貫通孔６１を貫通することで、バンドループ部６はバンド部４に取り付けられることになる。このとき、一対の内周部６３２は径方向においてバンド部４の幅方向における両縁部と対面してバンド部４を保持する。よって、内周部６３２および連結部（側面部６３４，６３５と、仕切り部６３３）からなる部分は、バンドループ部６の取付部６６として機能する。 The band loop portion 6 is attached to the band portion 4 by the band portion 4 (inner circumferential side band portion 43) penetrating the through hole 61. At this time, the pair of inner circumferential portions 632 faces the both edge portions in the width direction of the band portion 4 in the radial direction and holds the band portion 4. Therefore, a portion including the inner circumferential portion 632 and the connecting portion (the side portions 634 and 635 and the dividing portion 633) functions as the attaching portion 66 of the band loop portion 6.
　側面部６３４，６３５は、仕切り部６３３よりも外周側において、貫通孔６２を介して互いに対面している。また外周部６３１および仕切り部６３３は径方向において貫通孔６２を介して互いに対面している。外周部６３１の上記幅方向の両端はそれぞれ側面部６３４，６３５に連結される。 The side surface portions 634 and 635 face each other via the through holes 62 on the outer peripheral side of the partition portion 633. The outer peripheral portion 631 and the partition portion 633 face each other via the through hole 62 in the radial direction. Both ends in the width direction of the outer peripheral portion 631 are connected to the side surface portions 634 and 635, respectively.
　図５に示すように、係止部６５は貫通孔６２において外周側バンド部４４の凸部４１の少なくとも一つと係止する。係止部６５と凸部４１の係止により、外周側バンド部４４がバンドループ部６から抜けることを阻害する。つまり当該係止は、外周側バンド部４４がバンドループ部６に対して巻回方向Ｄ１とは反対の方向に移動することを阻害する。その一方で、外周側バンド部４４がバンドループ部６に対して巻回方向Ｄ１に沿って移動することを許容する。 As shown in FIG. 5, the locking portion 65 locks with at least one of the convex portions 41 of the outer peripheral side band portion 44 in the through hole 62. The locking of the locking portion 65 and the convex portion 41 prevents the outer peripheral side band portion 44 from coming off the band loop portion 6. That is, the locking inhibits the outer peripheral side band portion 44 from moving in the direction opposite to the winding direction D1 with respect to the band loop portion 6. On the other hand, the outer circumferential side band portion 44 is allowed to move relative to the band loop portion 6 along the winding direction D1.
　図４および図５では、例えば、係止部６５は貫通孔６２において内周側に設けられている。具体的には、係止部６５は仕切り部６３３のうち貫通孔６２側の部分に設けられている。これは、バンド部４が凸部４１および凹部４２を内周側に向けて電線９０に巻き付けられる場合を想定しているからである。もちろん、バンド部４が凸部４１および凹部４２を外周側に向けて電線９０に巻き付けられてもよい。この場合、係止部６５は貫通孔６２において外周側に設けられ、内周側へと突出する。以下では、係止部６５が貫通孔６２において内周側に設けられる場合について述べる。 In FIGS. 4 and 5, for example, the locking portion 65 is provided on the inner peripheral side of the through hole 62. Specifically, the locking portion 65 is provided in a portion of the partition portion 633 on the side of the through hole 62. This is because it is assumed that the band portion 4 is wound around the electric wire 90 with the convex portion 41 and the concave portion 42 directed to the inner peripheral side. Of course, the band portion 4 may be wound around the electric wire 90 with the convex portion 41 and the concave portion 42 directed to the outer peripheral side. In this case, the locking portion 65 is provided on the outer peripheral side in the through hole 62 and protrudes to the inner peripheral side. Hereinafter, the case where the locking portion 65 is provided on the inner peripheral side of the through hole 62 will be described.
　係止部６５は係止突部６５１を備えている。係止突部６５１は外周側に突出している。また係止突部６５１は径方向に揺動可能である。例えば係止部６５は、外周部６３１側から内周部６３２に向けて弾性変形する梁部６５２も備えている。梁部６５２は周方向に延びており、その周方向における両側にてそれぞれ固定端と自由端とを有している。固定端は本体部６３に固定される。この梁部６５２は自由端側において径方向に撓むことができる。係止突部６５１は梁部６５２のうち外周側の面に設けられている。梁部６５２が径方向において撓むことで、係止突部６５１の位置が径方向において移動する。 The locking portion 65 is provided with a locking projection 651. The locking projection 651 protrudes outward. The locking projection 651 is swingable in the radial direction. For example, the locking portion 65 also includes a beam portion 652 that elastically deforms toward the inner peripheral portion 632 from the outer peripheral portion 631 side. The beam portion 652 extends in the circumferential direction and has a fixed end and a free end on both sides in the circumferential direction. The fixed end is fixed to the main body 63. The beam portion 652 can be bent radially at the free end side. The locking projection 651 is provided on the outer surface of the beam portion 652. By bending the beam portion 652 in the radial direction, the position of the locking projection 651 moves in the radial direction.
　図５を参照して、係止突部６５１は側面６５ａ，６５ｂを備えている。側面６５ａ，６５ｂは係止突部６５１の周方向の両側の側面である。側面６５ａは側面６５ｂに対して巻回方向Ｄ１の上流側に位置している。つまり側面６５ａは側面６５ｂに対して基端４ｂ側に位置している。図５に示すように、側面６５ａの周方向に対する傾斜は側面６５ｂの傾斜よりも緩やかである。例えば側面６５ｂは周方向に対して略直交している。 Referring to FIG. 5, the locking projection 651 includes side surfaces 65a and 65b. The side surfaces 65 a and 65 b are side surfaces on both sides in the circumferential direction of the locking projection 651. The side surface 65a is located upstream of the side surface 65b in the winding direction D1. That is, the side surface 65a is located on the proximal end 4b side with respect to the side surface 65b. As shown in FIG. 5, the inclination of the side surface 65a with respect to the circumferential direction is gentler than the inclination of the side surface 65b. For example, the side surface 65b is substantially orthogonal to the circumferential direction.
　外周側バンド部４４をバンドループ部６に対して巻回方向Ｄ１に沿って移動させると、凸部４１が側面６５ａに当接する。側面６５ａの傾斜は緩やかなので、この移動によって係止突部６５１が凸部４１から受ける力は内周側に向かいやすく、係止突部６５１を内周側へと押すことができる。よって、梁部６５２が撓んで係止突部６５１は内周側に移動する。これにより、凸部４１が係止突部６５１を内周側に押し上げながら、巻回方向Ｄ１に沿って移動する。このように外周側バンド部４４はバンドループ部６に対して巻回方向Ｄ１へと移動できる。 When the outer circumferential side band portion 44 is moved along the winding direction D1 with respect to the band loop portion 6, the convex portion 41 abuts on the side surface 65a. Since the inclination of the side surface 65a is gentle, the force that the locking projection 651 receives from the convex portion 41 by this movement tends to be directed to the inner circumferential side, and the locking projection 651 can be pushed to the inner circumferential side. Thus, the beam portion 652 bends and the locking projection 651 moves to the inner peripheral side. As a result, the convex portion 41 moves along the winding direction D1 while pushing up the locking projection 651 to the inner peripheral side. Thus, the outer circumferential side band portion 44 can move relative to the band loop portion 6 in the winding direction D1.
　他方、外周側バンド部４４をバンドループ部６に対して巻回方向Ｄ１とは反対方向に移動させようとすると、凸部４１が側面６５ｂに当接する。側面６５ｂの傾斜は急峻なので、凸部４１から受ける力は内周側に向かいにくく、係止突部６５１が凸部４１に係止される。これにより、外周側バンド部４４の移動が阻害される。したがって、外周側バンド部４４がバンドループ部６から抜けることを阻害できる。 On the other hand, when attempting to move the outer peripheral side band portion 44 in the direction opposite to the winding direction D1 with respect to the band loop portion 6, the convex portion 41 abuts on the side surface 65b. Since the slope of the side surface 65 b is steep, the force received from the convex portion 41 is unlikely to be directed to the inner circumferential side, and the locking projection 651 is locked to the convex portion 41. Thereby, the movement of the outer peripheral side band portion 44 is inhibited. Therefore, the outer circumferential side band portion 44 can be inhibited from coming off the band loop portion 6.
　図５に例示するように、周方向において複数（例えば２つ）の係止突部６５１が設けられてもよい。各係止突部６５１は外周側バンド部４４の各凹部４２に嵌る。つまり係止突部６５１のピッチは凹部４２のピッチ（凸部４１のピッチ）とほぼ等しい。 As illustrated in FIG. 5, a plurality of (for example, two) locking projections 651 may be provided in the circumferential direction. The respective locking projections 651 fit into the respective recesses 42 of the outer peripheral side band portion 44. That is, the pitch of the locking projection 651 is substantially equal to the pitch of the recess 42 (pitch of the projection 41).
　＜作業手順＞
　次に、結束具１０を電線９０に取り付ける手順について述べる。図６から図８は、結束具１０を用いて電線９０を結束する様子の一例を示す図である。作業者は、図６に例示するように、電線９０を外周側から囲むようにバンド部４を曲げつつ、バンド部４をその先端４ａからヘッド部５（より具体的には貫通孔５１）に通す。次に、バンド部４の先端４ａをヘッド部５から遠ざけるようにバンド部４を引っ張る。これにより、図７に示すように内周側バンド部４３が電線９０に巻き付く。また図７の例示では、外周側バンド部４４はヘッド部５からその接線方向に延在している。つまり、外周側バンド部４４は電線９０から離れて延在する。この状態では、外周側バンド部４４は、車両に設けられる他の部材に干渉しやすい。 <Work procedure>
Next, the procedure for attaching the binding 10 to the wire 90 will be described. 6-8 is a figure which shows an example of a mode that the electric wire 90 is bound using the binding tool 10. FIG. The worker bends the band 4 so as to surround the electric wire 90 from the outer peripheral side, as illustrated in FIG. 6, and cuts the band 4 from the tip 4a to the head 5 (more specifically, the through hole 51). Pass through. Next, the band 4 is pulled so as to move the tip 4 a of the band 4 away from the head 5. Thereby, as shown in FIG. 7, the inner circumferential side band portion 43 is wound around the electric wire 90. Further, in the example of FIG. 7, the outer circumferential side band portion 44 extends from the head portion 5 in the tangential direction. That is, the outer peripheral side band portion 44 extends away from the electric wire 90. In this state, the outer circumferential band portion 44 easily interferes with other members provided in the vehicle.
　そこで作業者は、図８に示すように、外周側バンド部４４の先端４ａをバンドループ部６（より具体的には貫通孔６２）に通す。これにより、外周側バンド部４４の先端４ａを電線９０に近い位置で保持することができる。しかるに、この状態では、外周側バンド部４４はヘッド部５およびバンドループ部６との間において外周側に膨らみ得る。このような膨らみはワイヤハーネスのサイズを増大させるので好ましくない。この場合、作業者はバンドループ部６を内周側バンド部４３に対して巻回方向Ｄ１に沿って移動させることで、当該膨らみを解消する。これにより、図３に示すように、外周側バンド部４４を内周側バンド部４３に沿って延在させることができる。 Then, as shown in FIG. 8, the worker passes the tip 4a of the outer peripheral side band portion 44 through the band loop portion 6 (more specifically, the through hole 62). Thereby, the tip 4 a of the outer peripheral side band portion 44 can be held at a position close to the electric wire 90. However, in this state, the outer circumferential side band portion 44 can bulge to the outer circumferential side between the head portion 5 and the band loop portion 6. Such a bulge is not preferable because it increases the size of the wire harness. In this case, the worker moves the band loop portion 6 with respect to the inner circumferential side band portion 43 along the winding direction D1 to eliminate the swelling. Thereby, as shown in FIG. 3, the outer circumferential side band portion 44 can be extended along the inner circumferential side band portion 43.
　以上のように、外周側バンド部４４を電線９０に近い位置で保持するので、外周側バンド部４４が他の部材に干渉することを抑制できる。また外周側バンド部４４を切断する必要性を低減できる。外周側バンド部４４を切断しない場合には、次の事態を回避できる。即ち、電線９０をハーネス図版に載置した状態で外周側バンド部４４を切断する場合、その切断用の治具がハーネス図版に干渉することがある。これは作業性を低下させる。外周側バンド部４４を切断しない場合には、このような事態が生じないので、作業性の低下を招かない。 As mentioned above, since the outer peripheral side band part 44 is hold | maintained in the position close | similar to the electric wire 90, it can suppress that the outer peripheral side band part 44 interferes with another member. Further, the necessity of cutting the outer circumferential side band portion 44 can be reduced. When the outer peripheral side band portion 44 is not cut, the following situation can be avoided. That is, when the outer peripheral side band portion 44 is cut in a state where the electric wire 90 is placed on the harness drawing, a jig for the cutting may interfere with the harness drawing. This reduces the workability. In the case where the outer circumferential side band portion 44 is not cut off, such a situation does not occur, so that the workability is not reduced.
　＜貫通孔６１の開口＞
　上述の例では、一対の内周部６３２はバンド部４の幅方向において互いに離間している（図１および図４も参照）。また一対の内周部６３２はバンド部４の幅方向における両縁部と内周側から対面している。 <Opening of Through Hole 61>
In the above-described example, the pair of inner circumferential portions 632 are separated from each other in the width direction of the band portion 4 (see also FIGS. 1 and 4). Further, the pair of inner peripheral portions 632 face both edges in the width direction of the band portion 4 from the inner peripheral side.
　バンドループ部６は、一対の内周部６３２の間の間隔を広げるように、弾性変形可能であってもよい。これによれば、一対の内周部６３２の間の間隔を広げつつ、バンドループ部６を所望の位置でバンド部４に取り付けることができる。これにより、バンド部４が貫通孔６１を周方向（長手方向）に貫通することになる。 The band loop portion 6 may be elastically deformable so as to widen the distance between the pair of inner circumferential portions 632. According to this, the band loop portion 6 can be attached to the band portion 4 at a desired position while widening the distance between the pair of inner peripheral portions 632. As a result, the band portion 4 penetrates the through hole 61 in the circumferential direction (longitudinal direction).
　あるいは、バンド部４をその先端４ａ側からバンドループ部６に通してもよい。そしてバンドループ部６をバンド部４に対して基端４ｂ側へと所望の位置まで移動させても構わない。 Alternatively, the band portion 4 may be passed through the band loop portion 6 from the tip 4 a side thereof. Then, the band loop portion 6 may be moved to a desired position toward the proximal end 4 b with respect to the band portion 4.
　また貫通孔６１は必ずしも内周側に開口している必要はなく、内周側に閉じていても構わない。つまり一対の内周部６３２が互いに連結していても構わない。この場合でも、バンド部４をバンドループ部６の貫通孔６１に通すことができる。 Further, the through hole 61 does not necessarily have to be open on the inner peripheral side, and may be closed on the inner peripheral side. That is, the pair of inner circumferential portions 632 may be connected to each other. Even in this case, the band portion 4 can be passed through the through hole 61 of the band loop portion 6.
　＜貫通孔６１，６２＞
　図５の例示では、貫通孔６１，６２は仕切り部６３３によって径方向に互いに分離されている。しかしながら、貫通孔６１，６２は径方向に連通していても構わない。つまり、仕切り部６３３が、バンド部４の幅方向において互いに離間する一対の仕切り部６３３によって構成されていてもよい。 <Through holes 61, 62>
In the example of FIG. 5, the through holes 61 and 62 are radially separated from each other by a partition 633. However, the through holes 61 and 62 may communicate in the radial direction. That is, the partition portion 633 may be configured by a pair of partition portions 633 which are separated from each other in the width direction of the band portion 4.
　＜係止部６５＞
　上述の例では、係止部６５が設けられている。しかるに、係止部６５は必須ではない。係止部６５が設けられていなくても、バンドループ部６は外周側バンド部４４を電線９０に近い位置で保持できるからである。 <Locking portion 65>
In the above-mentioned example, the locking portion 65 is provided. However, the locking portion 65 is not essential. Even if the locking portion 65 is not provided, the band loop portion 6 can hold the outer peripheral side band portion 44 at a position close to the electric wire 90.
　しかしながら、係止部６５が設けられていることにより、外周側バンド部４４がバンドループ部６から抜けることを抑制できる。これにより、外周側バンド部４４をより確実に保持することができる。 However, the provision of the locking portion 65 can prevent the outer circumferential side band portion 44 from coming off the band loop portion 6. Thereby, the outer peripheral side band part 44 can be hold | maintained more reliably.
　＜留め具部＞
　また上述の例では、結束具１０は留め具部１を備えているものの、留め具部１を備えていなくてもよい。上述の説明から明白なように、留め具部１は電線９０に対する外周側バンド部４４の保持には寄与しないからである。 <Fastening part>
Moreover, in the above-mentioned example, although the binder 10 is equipped with the fastener part 1, it is not necessary to provide the fastener part 1. FIG. As is apparent from the above description, the fastener portion 1 does not contribute to the retention of the outer peripheral band portion 44 to the electric wire 90.
　第２の実施の形態．
　第１の実施の形態では図３の状態において、バンドループ部６は巻回方向Ｄ１には移動しにくい。なぜなら、係止部６５と凸部４１との係止によって、バンドループ部６は外周側バンド部４４に対する巻回方向Ｄ１への移動を阻害するからである。その一方で、バンドループ部６はその反対方向に移動可能である。例えば外周側バンド部４４が外周側に膨らむこと（図８参照）で、バンドループ部６の当該移動が許容される。あるいは、バンドループ部６が外周側バンド部４４に対して当該反対方向に移動する。後者の場合、図９に示すように、外周側バンド部４４がバンドループ部６から突出する部分が長くなり、先端４ａが電線９０から離れることになる。 Second Embodiment
In the first embodiment, in the state of FIG. 3, the band loop portion 6 does not easily move in the winding direction D1. This is because the band loop portion 6 inhibits movement in the winding direction D1 with respect to the outer peripheral side band portion 44 by the locking of the locking portion 65 and the convex portion 41. On the other hand, the band loop portion 6 is movable in the opposite direction. For example, the movement of the band loop portion 6 is permitted when the outer circumferential side band portion 44 bulges toward the outer circumferential side (see FIG. 8). Alternatively, the band loop portion 6 moves in the opposite direction with respect to the outer circumferential side band portion 44. In the latter case, as shown in FIG. 9, the portion of the outer circumferential side band portion 44 protruding from the band loop portion 6 is long, and the tip 4 a is separated from the electric wire 90.
　そこで第２の実施の形態では、バンドループ部６の巻回方向Ｄ１とは反対の方向における移動を阻害する。第２の実施の形態では、主に第１の実施の形態との相違点について述べる。第２の実施の形態にかかる結束具１０の一例は図１から図３と同様である。ただしバンドループ部６の構造が相違する。図１０および図１１はバンドループ部６の構成の一例を概略的に示す図である。図１０では、周方向に沿って見たバンドループ部６が示されている。図１１は、図１０のＸＩ－ＸＩ断面を概略的に示している。なお図１１では、バンド部４も示されている。 Therefore, in the second embodiment, the movement of the band loop portion 6 in the direction opposite to the winding direction D1 is inhibited. The second embodiment mainly describes differences from the first embodiment. An example of the binding device 10 according to the second embodiment is the same as in FIGS. 1 to 3. However, the structure of the band loop unit 6 is different. 10 and 11 schematically show an example of the configuration of the band loop unit 6. As shown in FIG. In FIG. 10, the band loop part 6 seen along the circumferential direction is shown. FIG. 11 schematically shows the XI-XI cross section of FIG. In FIG. 11, the band 4 is also shown.
　第２の実施の形態では、バンドループ部６は係止部６４を更に備えている。係止部６４は貫通孔６１において内周側バンド部４３の凸部４１の少なくとも一つと係止する。係止部６４は係止部６５よりも内周側（外周部６３１に対して貫通孔６２よりも遠い側）に位置する。なお第２の実施の形態では、貫通孔６１は一対の内周部６３２、連結部（側面部６３４，６３５および仕切り部６３３）および係止部６４によって形成される。 In the second embodiment, the band loop portion 6 further includes a locking portion 64. The locking portion 64 locks with at least one of the convex portions 41 of the inner circumferential side band portion 43 in the through hole 61. The locking portion 64 is located on the inner peripheral side of the locking portion 65 (the side farther from the outer circumferential portion 631 than the through hole 62). In the second embodiment, the through hole 61 is formed by the pair of inner peripheral portions 632, the connecting portions (the side portions 634 and 635 and the partition portion 633) and the locking portion 64.
　この係止部６４は、バンドループ部６による巻回方向Ｄ１への移動を許容し、その反対方向の移動を凸部４１との係止によって阻害する。つまり、バンドループ部６は内周側バンド部４３に対して巻回方向Ｄ１へと移動できるものの、その反対方向の移動は阻害される。換言すれば、係止部６４の内周側バンド部４３に対する係止方向は、係止部６５の外周側バンド部４４に対する係止方向とは反対である。 The locking portion 64 allows the band loop portion 6 to move in the winding direction D1, and the movement in the opposite direction is blocked by locking with the convex portion 41. That is, although the band loop portion 6 can move in the winding direction D1 with respect to the inner circumferential side band portion 43, the movement in the opposite direction is inhibited. In other words, the locking direction of the locking portion 64 with respect to the inner circumferential side band portion 43 is opposite to the locking direction of the locking portion 65 with respect to the outer circumferential side band portion 44.
　ここでは一例として、凸部４１および凹部４２が内周側を向くように、バンド部４が曲げられる。よって係止部６４はこの凸部４１と係止すべく、内周部６３２に設けられている。係止部６４は内周部６３２から外周側に突出する突部として形成される。また係止部６４は径方向に揺動可能である。例えば図１０においては、一対の内周部６３２はそれぞれ側面部６３４，６３５に固定されており、また一対の内周部６３２の間には間隙が形成されている。つまり一対の内周部６３２は、それぞれ側面部６３４，６３５側の固定端と、自由端とを含む片持ち梁構造を有している。よって内周部６３２はその自由端側において径方向に撓む。係止部６４は自由端側において内周部６３２に設けられており、内周部６３２の撓みに伴って径方向において移動する。 Here, as an example, the band portion 4 is bent so that the convex portion 41 and the concave portion 42 face the inner peripheral side. Therefore, the locking portion 64 is provided on the inner circumferential portion 632 in order to lock with the convex portion 41. The locking portion 64 is formed as a projection that protrudes from the inner circumferential portion 632 to the outer circumferential side. Further, the locking portion 64 can swing in the radial direction. For example, in FIG. 10, the pair of inner circumferential portions 632 is fixed to the side surface portions 634 and 635, respectively, and a gap is formed between the pair of inner circumferential portions 632. That is, the pair of inner circumferential portions 632 have a cantilever structure including a fixed end on the side surface portions 634 and 635 and a free end. Thus, the inner circumferential portion 632 is bent radially at its free end. The locking portion 64 is provided on the inner circumferential portion 632 at the free end side, and moves in the radial direction as the inner circumferential portion 632 bends.
　図１１を参照して、係止部６４は側面６４ａ，６４ｂを備えている。側面６４ａ，６４ｂは係止部６４の周方向における両端の側面である。側面６４ａは巻回方向Ｄ１において側面６４ｂよりも上流側に位置している。つまり側面６４ａは側面６４ｂに対して基端４ｂ側に位置している。図１１に示すように、側面６４ｂの内周部６３２に対する傾斜は、側面６４ａの内周部６３２に対する傾斜よりも緩やかである。例えば側面６４ａは内周部６３２に対して略直交する。 Referring to FIG. 11, the locking portion 64 includes side surfaces 64a and 64b. The side surfaces 64 a and 64 b are side surfaces of both ends in the circumferential direction of the locking portion 64. The side surface 64a is located upstream of the side surface 64b in the winding direction D1. That is, the side surface 64a is located on the proximal end 4b side with respect to the side surface 64b. As shown in FIG. 11, the slope of the side surface 64 b with respect to the inner circumferential portion 632 is gentler than the slope of the side surface 64 a with respect to the inner circumferential portion 632. For example, the side surface 64 a is substantially orthogonal to the inner circumferential portion 632.
　バンドループ部６を内周側バンド部４３に対して巻回方向Ｄ１へと移動させると、側面６４ｂが凸部４１に当接する。側面６４ｂの傾斜は緩やかなので、この移動によって係止部６４が凸部４１から受ける力は内周側に向かいやすく、係止部６４を内周側へと押すことができる。これにより、係止部６４は内周側に移動し、係止部６４と凸部４１との係止が解除される。これにより、バンドループ部６は内周側バンド部４３に対して巻回方向Ｄ１へと移動できる。 When the band loop portion 6 is moved in the winding direction D1 with respect to the inner circumferential side band portion 43, the side surface 64b abuts on the convex portion 41. Since the inclination of the side surface 64 b is gentle, the force that the locking portion 64 receives from the convex portion 41 by this movement tends to be directed to the inner circumferential side, and the locking portion 64 can be pushed to the inner circumferential side. Thereby, the locking portion 64 moves to the inner peripheral side, and the locking between the locking portion 64 and the convex portion 41 is released. Thus, the band loop portion 6 can move in the winding direction D1 with respect to the inner circumferential side band portion 43.
　したがって第２の実施の形態でも、図８に示す外周側バンド部４４の膨らみを、バンドループ部６を巻回方向Ｄ１へと移動させることで、解消することができる。このようにバンドループ部６を巻回方向Ｄ１へと移動させても、その移動方向はバンドループ部６と外周側バンド部４４とが係止する方向である。よってかかる移動がバンドループ部６と外周側バンド部４４とが係止する位置を変えることはない。 Therefore, also in the second embodiment, the swelling of the outer peripheral side band portion 44 shown in FIG. 8 can be eliminated by moving the band loop portion 6 in the winding direction D1. Thus, even if the band loop portion 6 is moved in the winding direction D1, the moving direction is the direction in which the band loop portion 6 and the outer peripheral side band portion 44 are locked. Therefore, such movement does not change the position at which the band loop portion 6 and the outer peripheral side band portion 44 are locked.
　他方、巻回方向Ｄ１とは反対方向にバンドループ部６を内周側バンド部４３に対して移動させると、側面６４ａが凸部４１に当接する。側面６４ａの傾斜は急峻なので、凸部４１から受ける力は内周側に向かいにくく、係止部６４が凸部４１に係止される。これにより、巻回方向Ｄ１とは反対方向のバンドループ部６の移動が阻害される。 On the other hand, when the band loop portion 6 is moved relative to the inner circumferential side band portion 43 in the direction opposite to the winding direction D 1, the side surface 64 a abuts on the convex portion 41. Since the slope of the side surface 64 a is steep, the force received from the convex portion 41 is unlikely to be directed to the inner circumferential side, and the locking portion 64 is locked to the convex portion 41. Thereby, the movement of the band loop portion 6 in the opposite direction to the winding direction D1 is inhibited.
　したがって、図３に示す状態が図８または図９に示す状態に変わることを抑制できる。つまり、外周側バンド部４４が外側に膨らんだり、あるいは、先端４ａが電線９０から離れることを抑制できる。 Therefore, it can suppress that the state shown in FIG. 3 changes to the state shown in FIG. 8 or FIG. That is, it is possible to suppress that the outer circumferential side band portion 44 bulges outward, or that the tip 4a is separated from the electric wire 90.
　係止部６４は図１０に例示するように一対の内周部６３２の両方に設けられてもよい。あるいは、一対の内周部６３２の一方のみに係止部６４が設けられても構わない。また図１１に例示するように、複数（例えば２つ）の係止部６４が長手方向に並んで設けられてもよい。各係止部６４は内周側バンド部４３の各凹部４２に嵌る。つまり係止部６４のピッチは凹部４２のピッチ（凸部４１のピッチ）とほぼ等しい。 The locking portion 64 may be provided on both of the pair of inner circumferential portions 632 as illustrated in FIG. 10. Alternatively, the locking portion 64 may be provided on only one of the pair of inner circumferential portions 632. Further, as illustrated in FIG. 11, a plurality of (for example, two) locking portions 64 may be provided side by side in the longitudinal direction. Each locking portion 64 is fitted into each recess 42 of the inner circumferential band portion 43. That is, the pitch of the locking portion 64 is substantially equal to the pitch of the concave portion 42 (pitch of the convex portion 41).
　＜貫通孔６１の開口＞
　図１０の例示では、一対の内周部６３２は互いに離間している。貫通孔６１は、この一対の内周部６３２と、連結部（側面部６３４，６３５および仕切り部６３３）と、係止部６４とによって形成されて、一対の内周部６３２の間において内周側に開口している。またバンドループ部６は、一対の内周部６３２の間の間隔を広げるように弾性変形可能であってもよい。これによれば、第１の実施の形態と同様に、一対の内周部６３２の間の間隔を広げつつ、バンドループ部６を所望の位置でバンド部４に取り付けることができる。 <Opening of Through Hole 61>
In the illustration of FIG. 10, the pair of inner circumferential portions 632 are separated from each other. The through hole 61 is formed by the pair of inner peripheral portions 632, the connecting portion (the side portions 634 and 635 and the partition portion 633), and the locking portion 64, and the inner peripheral portion between the pair of inner peripheral portions 632 is formed. It is open to the side. Further, the band loop portion 6 may be elastically deformable so as to widen the distance between the pair of inner circumferential portions 632. According to this, as in the first embodiment, the band loop portion 6 can be attached to the band portion 4 at a desired position while widening the distance between the pair of inner circumferential portions 632.
　第２の実施の形態では、バンドループ部６がバンド部４に取り付けられると、係止部６４と凸部４１との係止によって、バンドループ部６による基端４ｂ側への移動が阻害される。つまりこの係止を解除しなければ、バンドループ部６を基端４ｂ側に移動させることができない。したがって、バンドループ部６は基端４ｂに近い位置でバンド部４に取り付けられることが望ましい。つまり、予めバンドループ部６を基端４ｂに近い位置に取り付けることで、係止を解除することなく移動可能な範囲（バンドループ部６から先端４ａまでの範囲）を広く設定するのである。これによれば、バンドループ部６の位置の調整を広い範囲で簡単に行うことができる。 In the second embodiment, when the band loop portion 6 is attached to the band portion 4, the movement of the band loop portion 6 to the proximal end 4 b side is inhibited by the locking between the locking portion 64 and the convex portion 41. Ru. That is, the band loop portion 6 can not be moved to the proximal end 4 b side unless the locking is released. Therefore, it is desirable that the band loop portion 6 be attached to the band portion 4 at a position close to the proximal end 4 b. That is, by attaching the band loop portion 6 at a position close to the base end 4b in advance, the movable range (the range from the band loop portion 6 to the tip 4a) can be set wide without releasing the locking. According to this, the adjustment of the position of the band loop portion 6 can be easily performed in a wide range.
　その一方で、貫通孔６１は内周側において閉じていても構わない。図１２および図１３はバンドループ部６の構成の一例を概略的に示す図である。図１２では、周方向に沿って見たバンドループ部６が示されている。図１３は、図１２のＸＩＩＩ－ＸＩＩＩ断面を概略的に示している。なお図１３では、バンド部４も示されている。 On the other hand, the through hole 61 may be closed on the inner peripheral side. 12 and 13 schematically show an example of the configuration of the band loop unit 6. As shown in FIG. In FIG. 12, the band loop part 6 seen along the circumferential direction is shown. FIG. 13 schematically shows the XIII-XIII cross section of FIG. The band 4 is also shown in FIG.
　図１２の例示では図１０と比較して、内周部６３２がその両端において側面部６３４，６３５に連結されており、貫通孔６１が内周側にも閉じている。また図１３の例示では、係止部６４は係止部６５と同様の構成を有している。ただし、その係止方向は互いに逆になる。 Compared with FIG. 10 in the example of FIG. 12, the inner peripheral part 632 is connected with the side part 634, 635 in the both ends, and the through-hole 61 is closed also to the inner peripheral side. Further, in the example of FIG. 13, the locking portion 64 has the same configuration as the locking portion 65. However, the locking directions are opposite to each other.
　このようなバンドループ部６は、例えば次のようにバンド部４に取り付けることができる。例えば係止部６４による係止を解除しながら、バンド部４をその先端４ａから貫通孔６１に通す。そして係止の解除を維持しつつ、バンドループ部６をバンド部４に対して所望の位置まで基端４ｂ側に移動させる。これにより、バンドループ部６をバンド部４に取り付けることができる。 Such a band loop portion 6 can be attached to the band portion 4 as follows, for example. For example, while releasing the locking by the locking portion 64, the band 4 is passed from the tip 4a to the through hole 61. And the band loop part 6 is moved to the base end 4b side with respect to the band part 4 to a desired position, maintaining cancellation | release of latching. Thereby, the band loop part 6 can be attached to the band part 4.
　以上のように、貫通孔６１は内周側に閉じていてもよいものの、バンドループ部６をバンド部４に取り付けることに鑑みれば、貫通孔６１は内周側に開口していることが望ましい。なぜなら、上述のように、係止の解除を行うことなく一対の内周部６３２の間からバンドループ部６をバンド部４に取り付けることができるからである。 As described above, although the through hole 61 may be closed to the inner peripheral side, it is preferable that the through hole 61 is opened to the inner peripheral side in view of attaching the band loop portion 6 to the band portion 4 . This is because, as described above, the band loop portion 6 can be attached to the band portion 4 from between the pair of inner peripheral portions 632 without releasing the locking.
