Description

本発明は、ワイヤ等の被支持部材を結束バンドで締め付けて支持する結束バンド用支持部材に関するものである。   The present invention relates to a binding band support member that supports a supported member such as a wire by tightening the support member with a binding band.

従来から、自動車等において通電ワイヤや伝動ワイヤ、電装部品等を車両パネルや電装品本体等で支持させるのに、平形の結束バンドが利用されている。この結束バンドは、例えば特開平１０−３７９１７号公報（特許文献１）に記載されているように、帯状部の一方の端部に挿通係止部が一体形成されている。また、帯状部の一方の平面には鋸歯状の係止突起が形成されていると共に、挿通係止部には帯状部が挿通される挿通孔が形成されており、挿通孔の内部に突出して係止片が設けられている。そして、帯状部を他方の端部から挿通孔に挿通させることにより、係止突起に対する係止片の係止作用で帯状部の挿通孔からの抜出しが阻止されて、対象物を弛緩不能に締め付けることが出来るようになっている。   2. Description of the Related Art Conventionally, a flat binding band has been used to support a current-carrying wire, a transmission wire, an electrical component, or the like in a vehicle or the like with a vehicle panel or an electrical component body. In this binding band, for example, as described in JP-A-10-37917 (Patent Document 1), an insertion locking portion is integrally formed at one end portion of the band-shaped portion. In addition, a serrated locking projection is formed on one plane of the band-shaped portion, and an insertion hole is formed in the insertion locking portion to allow the band-shaped portion to pass therethrough, and protrudes into the insertion hole. A locking piece is provided. And by letting the strip-shaped portion pass through the insertion hole from the other end, the locking piece locks against the locking projection, so that the strip-shaped portion is prevented from being pulled out from the insertion hole, and the object is tightened in a non-relaxable manner. It can be done.

ところで、この結束バンドを用いてワイヤ等の被支持部材を車両パネル等の支持部材に対して締め付けて固定的に支持させるためには、例えば特開２００６−１６６６２１号公報（特許文献２）に記載されているように、支持部材に一対のバンド挿通穴を形成する。そして、結束バンドをこれら一対のバンド挿通穴に順次に挿し通すと共に、帯状部を被支持部材に巻き付けてから挿通係止部の挿通孔に挿通させて締め付けるようにされる。   By the way, in order to clamp and support a supported member such as a wire with respect to a support member such as a vehicle panel using this binding band, it is described in, for example, Japanese Patent Application Laid-Open No. 2006-166621 (Patent Document 2). As shown, a pair of band insertion holes are formed in the support member. Then, the binding band is sequentially inserted into the pair of band insertion holes, and the band-like portion is wound around the supported member and then inserted into the insertion hole of the insertion locking portion to be tightened.

ところが、支持部材のバンド挿通穴に結束バンドの帯状部を挿し通す際に、結束バンドに形成された係止突起がバンド挿通穴の内面や開口縁部に引っ掛かってしまうことがあった。そのために、バンド挿通穴に対して結束バンドを挿し通す作業が面倒で、時間もかかるという問題があったのである。   However, when the band-shaped portion of the binding band is inserted through the band insertion hole of the support member, the locking protrusion formed on the binding band may be caught on the inner surface or the opening edge of the band insertion hole. For this reason, the work of inserting the binding band into the band insertion hole is troublesome and takes time.

特に、一対のバンド挿通穴は、支持部材において互いに平行に貫通形成されることが多く、一方のバンド挿通穴に挿し通した帯状部を折り返し変形させて他方のバンド挿通穴に挿し通す必要がある。その際、帯状部が弾性で復元することから、バンド挿通穴の内面や開口縁部に対して帯状部が押し付けられて、係止突起の引っ掛かりが一層問題となり易い。   In particular, the pair of band insertion holes are often formed through the support member in parallel with each other, and it is necessary to fold and deform the band-shaped portion inserted into one band insertion hole and insert it into the other band insertion hole. . At that time, since the belt-like portion is elastically restored, the belt-like portion is pressed against the inner surface and the opening edge of the band insertion hole, and the catch of the locking protrusion is more likely to be a problem.

また、一対のバンド挿通穴に挿し通した帯状部を挿通係止部の挿通孔に挿通させて締め付ける際にも、締付力によって、バンド挿通穴の内面や開口縁部に対して帯状部が押し付けられ易い。このように、帯状部をバンド挿通穴へ挿し通したり締め付けたりする際に、バンド挿通穴の内面や開口縁部に対して帯状部が押し付けられつつ移動させられると、帯状部に形成された係止突起が潰れてしまうこともある。その結果、係止突起に対する係止片の係止力が充分に発揮され難くなり、支持部材による被支持部材の支持力の安定性や信頼性が低下してしまうおそれもあった。   Also, when the band-like part inserted through the pair of band insertion holes is inserted into the insertion hole of the insertion locking part and tightened, the band-like part is formed against the inner surface and the opening edge of the band insertion hole by the tightening force. Easy to be pressed. As described above, when the band-shaped part is inserted into the band insertion hole or is tightened, if the band-shaped part is moved while being pressed against the inner surface or the opening edge of the band insertion hole, the engagement formed in the band-shaped part. The stop protrusion may be crushed. As a result, it is difficult to sufficiently exert the locking force of the locking piece with respect to the locking protrusion, and the stability and reliability of the supporting force of the supported member by the supporting member may be reduced.

特開平１０−３７９１７号公報Japanese Patent Laid-Open No. 10-37917 特開２００６−１６６６２１号公報JP 2006-166621 A

本発明は上述の事情を背景に為されたものであって、その解決課題は、結束バンドをバンド挿通穴に挿し通したり締め付けたりする際の引っ掛かりが防止されて、結束バンドを容易に装着することが出来ると共に、結束バンドの締付力も安定して発揮され得る、新規な構造の結束バンド用支持部材を提供することにある。   The present invention has been made in the background of the above-mentioned circumstances, and the problem to be solved is that the binding band can be easily attached by being prevented from being caught when the binding band is inserted into the band insertion hole or tightened. An object of the present invention is to provide a binding band support member having a novel structure that can be used and that the binding band can be stably tightened.

本発明の第一の態様は、バンド挿通穴が形成されており、片面に鋸歯状の係止突起が形成された平形の結束バンドを前記バンド挿通穴に挿通すると共に被支持部材に巻き付けて締めることにより該被支持部材を固定的に支持する結束バンド用支持部材において、前記バンド挿通穴を長穴形状とし、少なくとも前記係止突起が形成された前記結束バンドの前記片面が対向する側の長辺部が外方に膨らむ凹形状とされていると共に、一対の前記バンド挿通穴が短辺方向で互いに離隔して長辺方向で互いに平行となるように形成されており、前記一対のバンド挿通穴の少なくとも外側の長辺部がそれぞれ凹形状とされていることを、特徴とする。 In the first aspect of the present invention, a band binding hole is formed, and a flat binding band having a serrated locking projection formed on one side is inserted into the band insertion hole and wound around a supported member and tightened. Accordingly, in the binding band support member that fixedly supports the supported member, the band insertion hole has a long hole shape, and the length of the binding band on which the one side of the binding band on which at least the locking projection is formed is opposed to each other The pair of band insertion holes are formed in a concave shape that bulges outward, and the pair of band insertion holes are formed so as to be separated from each other in the short side direction and parallel to each other in the long side direction. It is characterized in that at least the outer long side portion of the hole is concave .

第一の態様の結束バンド用支持部材では、バンド挿通穴の長辺部に付された凹形状のへこみによって、そこに挿通される結束バンドにおける係止突起の形成面がバンド挿通穴の内周面から離隔され得る。これにより、結束バンドのバンド挿通穴への挿通時や締付時におけるバンド挿通穴への引っ掛かりが防止される。その結果、結束バンドのバンド挿通穴への挿通作業や締付作業が容易になると共に、バンド挿通穴への引っ掛かりに起因する係止突起の潰れが防止されて係止突起による係止作用を安定して得ることが可能となる。   In the binding band support member according to the first aspect, the concave protrusion formed on the long side portion of the band insertion hole causes the formation surface of the locking projection in the binding band inserted therethrough to be the inner periphery of the band insertion hole. Can be spaced from the surface. This prevents the binding band from being caught in the band insertion hole during insertion into the band insertion hole or tightening. As a result, it is easy to insert and tighten the binding band into the band insertion hole and prevent the locking protrusion from being crushed due to being caught in the band insertion hole, thus stabilizing the locking action by the locking protrusion. Can be obtained.

なお、本態様では、従来周知の平形の結束バンドを用いることが可能であり、好適には、係止突起が形成された面の幅方向両側の縁部に沿って一対の突条部が形成された構造の結束バンドが用いられる。このような結束バンドでは、バンド挿通穴への挿通に際して、一対の突状部がバンド挿通穴の内周面に当接し、幅方向中央部分に形成された係止突起のバンド挿通穴の内周面への当接が一層効果的に防止され得る。尤も、本態様では、そのような突条部が形成されておらず、結束バンドの幅方向全体に延びる係止突起が形成された結束バンドも採用することが出来る。その場合でも、少なくとも結束バンドの幅方向中央部分では、バンド挿通穴の内周面に対する係止突起の当接が回避されることにより、前述の作用効果が発揮され得る。   In this aspect, a conventionally known flat binding band can be used, and preferably a pair of protrusions are formed along the edges on both sides in the width direction of the surface on which the locking protrusions are formed. A binding band having the structure described above is used. In such a binding band, when inserted into the band insertion hole, the pair of protrusions abut against the inner peripheral surface of the band insertion hole, and the inner periphery of the band insertion hole of the locking projection formed in the center portion in the width direction. Contact to the surface can be prevented more effectively. However, in this aspect, a binding band in which such a protrusion is not formed and a locking projection extending in the entire width direction of the binding band can be used. Even in such a case, at least in the central portion in the width direction of the binding band, the above-described effects can be exhibited by avoiding the contact of the locking projections with the inner peripheral surface of the band insertion hole.

また、本態様では、被支持部材に巻き付けた際の外周面が係止突起の形成された片面とされている結束バンドを採用するに際して、その係止突起のバンド挿通穴への引っ掛かりを防ぐことができる。特に、一対のバンド挿通穴に挿通するに際して、結束バンドが弾性で直線状に復元することにより一対のバンド挿通穴の外側の長辺部に係止突起が引っ掛かることを回避するのに有効である。 In addition, in this aspect, when a binding band in which the outer peripheral surface when wound around the supported member is a single surface on which a locking projection is formed is used, the locking projection is prevented from being caught in the band insertion hole. Can do. In particular, when inserting into the pair of band insertion holes, the binding band is elastically restored to a linear shape, which is effective in avoiding the hooking protrusion from being caught on the long side portion outside the pair of band insertion holes. .

本発明の第二の態様は、前記第一の態様の結束バンド用支持部材において、一対の前記バンド挿通穴が短辺方向で互いに離隔して長辺方向で互いに平行となるように形成されており、前記一対のバンド挿通穴の内側の長辺部もそれぞれ凹形状とされているものである。 According to a second aspect of the present invention, in the binding band support member according to the first aspect, the pair of band insertion holes are formed so as to be separated from each other in the short side direction and parallel to each other in the long side direction. cage, the long sides of the inner side of the pair of band insertion holes is also what is respectively concave.

第二の態様では、被支持部材に巻き付けた際の内周面が係止突起の形成された片面とされている結束バンドを採用するに際して、その係止突起のバンド挿通穴への引っ掛かりを防ぐことが出来る。特に、一対のバンド挿通穴に挿通した結束バンドを締め付けるに際して、結束バンドが締付力で変形することにより一対のバンド挿通穴の内側の長辺部に係止突起が引っ掛かることを回避するのに有効である。 In the second aspect, when adopting a binding band in which the inner peripheral surface when wound around the supported member is a single surface on which the locking projection is formed, the locking projection is prevented from being caught in the band insertion hole. I can do it. In particular, when tightening the binding band inserted through the pair of band insertion holes, the binding band is deformed by the tightening force to prevent the locking protrusion from being caught on the long side portion inside the pair of band insertion holes. It is valid.

本発明の第三の態様は、第一または第二の態様の結束バンド用支持部材において、外方に膨らむ凹形状とされた前記長辺部における両側開口のエッジ部には、角取りが形成されているものである。 According to a third aspect of the present invention, in the binding band support member according to the first or second aspect, chamfering is formed at the edge portions of both side openings in the long side portion that is formed in a concave shape that bulges outward. It is what has been.

第三の態様によれば、バンド挿通穴の開口部のエッジ状角部をＣ面やＲ面からなる角取り形状としたことで、エッジ状角部への結束バンドの引っ掛かりを防止できる。それ故、バンド挿通穴への結束バンドの引っ掛かり等を防止する本発明の効果がより有効に達成され得る。 According to the 3rd aspect, the edge-shaped corner | angular part of the opening part of a band penetration hole was made into the chamfering shape which consists of C surface and R surface, and can catch the binding band to an edge-shaped corner | angular part. Therefore, the effect of the present invention for preventing the binding band from being caught in the band insertion hole can be achieved more effectively.

本発明に従えば、結束バンドにおける係止突起の形成面とバンド挿通穴の内周面との間の距離を容易に且つ効果的に確保することが出来、それによって、結束バンドをバンド挿通穴に挿し通したり締め付けたりする際の係止突起の引っ掛かりが防止され得る。   According to the present invention, the distance between the formation surface of the locking projection in the binding band and the inner peripheral surface of the band insertion hole can be easily and effectively ensured, whereby the binding band can be secured to the band insertion hole. The locking projection can be prevented from being caught when inserted into or tightened.

以下、本発明を更に具体的に明らかにするために、本発明の実施形態について、図面を参照しつつ、詳細に説明する。   Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described in detail with reference to the drawings.

図１〜３には、結束バンド用支持部材に係る本発明の一実施形態としてのコネクタホルダ１０が示されている。コネクタホルダ１０には、被支持部材としてのワイヤハーネス１２が結束バンド１４で装着されている。   1-3, the connector holder 10 as one Embodiment of this invention which concerns on the binding band support member is shown. A wire harness 12 as a supported member is attached to the connector holder 10 with a binding band 14.

より詳細には、コネクタホルダ１０は、周知のとおりワイヤハーネス１２同士を接続するコネクタ接続部を収容して位置決め支持するものであり、ブラケットや固定ボルト等を用いて車体パネル等に固定される。本実施形態では、このコネクタホルダ１０が結束バンド支持部材を兼ねており、コネクタホルダ１０に収容されたコネクタ接続部から延び出したワイヤハーネス１２を所定の方向に引き出すガイド部１６が、コネクタホルダ１０の外部に設けられている。ガイド部１６には、ワイヤハーネス１２が嵌め入れられる凹溝１８が形成されており、この凹溝１８の底壁２０に一対のバンド挿通穴２２，２２が形成されている。   More specifically, the connector holder 10 houses and supports a connector connecting portion for connecting the wire harnesses 12 as is well known, and is fixed to a vehicle body panel or the like using a bracket, a fixing bolt, or the like. In this embodiment, the connector holder 10 also serves as a binding band support member, and the guide portion 16 that pulls out the wire harness 12 extending from the connector connection portion accommodated in the connector holder 10 in a predetermined direction is provided in the connector holder 10. It is provided outside. A concave groove 18 into which the wire harness 12 is inserted is formed in the guide portion 16, and a pair of band insertion holes 22, 22 are formed in the bottom wall 20 of the concave groove 18.

一対のバンド挿通穴２２，２２は、図４に示されているように、各一対の長辺部２４，２４と短辺部２８，２８からなる長穴形状の断面で底壁２０を板厚方向に貫通して形成されている。なお、コネクタホルダ１０の底壁２０は、平坦な平板形状とされており、一対のバンド挿通穴２２，２２が、短辺方向で互いに離隔して長辺方向で互いに平行となるように形成されている。即ち、これら一対のバンド挿通穴２２，２２は、長辺部２４，２４と平行に延びる中心線：Ｘに関して線対称となる位置および形状で、相互に離隔して形成されている。   As shown in FIG. 4, the pair of band insertion holes 22, 22 has a thickness of the bottom wall 20 in a cross section of a long hole shape including a pair of long side portions 24, 24 and short side portions 28, 28. It is formed to penetrate in the direction. The bottom wall 20 of the connector holder 10 has a flat plate shape, and is formed so that the pair of band insertion holes 22 and 22 are separated from each other in the short side direction and parallel to each other in the long side direction. ing. That is, the pair of band insertion holes 22 and 22 are spaced apart from each other at positions and shapes that are symmetric with respect to a center line X that extends in parallel with the long sides 24 and 24.

さらに、各バンド挿通穴２２は、両側の長辺部２４，２４が、何れも、外周側に向かって湾曲して膨らんだ凹形状とされている。これにより、バンド挿通穴２２の内周面のうち、両側の長辺部２４，２４の内周面が凹状湾曲面２９とされている。なお、各バンド挿通穴２２の両側の短辺部２８，２８は、互いに平行に延びる直線形状とされている。また、バンド挿通穴２２の四隅は、何れも、角のない円弧状部で長辺部２４と短辺部２８が滑らかに接続されている。   Further, each band insertion hole 22 has a concave shape in which the long side portions 24, 24 on both sides are curved and expanded toward the outer peripheral side. Accordingly, the inner peripheral surfaces of the long side portions 24, 24 on both sides of the inner peripheral surface of the band insertion hole 22 are formed as concave curved surfaces 29. In addition, the short side parts 28 and 28 on both sides of each band insertion hole 22 have a linear shape extending in parallel to each other. Further, the four corners of the band insertion hole 22 are all arc-shaped portions having no corners, and the long side portion 24 and the short side portion 28 are smoothly connected.

また、各バンド挿通穴２２は、その短辺部２８，２８の対向間距離、即ち長辺方向の開口幅が、挿通される結束バンド１４の幅寸法よりも大きくされている。一方、バンド挿通穴２２の長辺部２４，２４の対向面間距離、即ち短辺方向の開口幅は、その最大値において、結束バンド１４の厚さ寸法よりも大きいが幅寸法よりも小さくされている。これにより、バンド挿通穴２２に挿通された結束バンド１４における、バンド挿通穴２２内での表裏反転が防止されている。   In addition, each band insertion hole 22 has a distance between opposing short sides 28, that is, an opening width in the long side direction, larger than the width dimension of the binding band 14 to be inserted. On the other hand, the distance between the opposing surfaces of the long side portions 24, 24 of the band insertion hole 22, that is, the opening width in the short side direction is larger than the thickness dimension of the binding band 14 but smaller than the width dimension at the maximum value. ing. Thereby, inversion of the front and back in the band insertion hole 22 in the binding band 14 inserted in the band insertion hole 22 is prevented.

また、バンド挿通穴２２，２２における両側の開口周縁部であるエッジ部には、全周に亘って角取りが施されている。これにより、バンド挿通穴２２，２２の両側開口のエッジ部が、開口方向外方へ行くに従って次第に拡開する方向に傾斜した角取面３４，３４とされている。   Moreover, the edge part which is the opening peripheral part of the both sides in the band insertion holes 22 and 22 is rounded over the perimeter. Thereby, the edge part of the both-sides opening of the band penetration holes 22 and 22 is made into the chamfering surfaces 34 and 34 which inclined in the direction which expands gradually as it goes to an opening direction outward.

一対のバンド挿通穴２２，２２が形成された底壁２０に対してワイヤハーネス１２が重ね合わされることにより、ワイヤハーネス１２が凹溝１８に嵌め入れられて配索されている。また、一対のバンド挿通穴２２，２２には、結束バンド１４が挿し通されて装着されており、この結束バンド１４により、ワイヤハーネス１２が、凹溝１８内で底壁２０上に固定的に締め付けられている。   When the wire harness 12 is superimposed on the bottom wall 20 in which the pair of band insertion holes 22 and 22 are formed, the wire harness 12 is fitted in the recessed groove 18 and wired. In addition, a binding band 14 is inserted into and attached to the pair of band insertion holes 22, 22, and the wire harness 12 is fixed on the bottom wall 20 in the concave groove 18 by the binding band 14. It is tightened.

結束バンド１４は、図５に示されているように、長方形断面の細長い平板形状とされた帯状部３６を備えており、この帯状部３６の長さ方向一方の端部に挿通係止部３８が一体形成されている。周知のとおり、結束バンド１４は合成樹脂材料で一体成形されており、帯状部３６が湾曲変形可能となっている。   As shown in FIG. 5, the binding band 14 includes a belt-like portion 36 having a long and flat plate shape with a rectangular cross section, and an insertion locking portion 38 at one end in the length direction of the belt-like portion 36. Are integrally formed. As is well known, the binding band 14 is integrally formed of a synthetic resin material, and the belt-like portion 36 can be bent and deformed.

また、帯状部３６には、厚さ方向の一方となる片面４０において、鋸歯状の係止突起４２が帯状部３６の長手方向に多数並んで形成されている。また、この係止突起４２が形成された帯状部３６の片面４０には、その幅方向の両端縁部に一対の突条部４４，４４が形成されている。この一対の突条部４４，４４は、帯状部３６の略全長に亘って延びており、両突条部４４，４４間に跨がって帯状部３６の幅方向に延びるようにして各係止突起４２が形成されている。   In addition, a large number of serrated locking projections 42 are formed side by side in the longitudinal direction of the band-like part 36 on one side 40 which is one side in the thickness direction. In addition, a pair of protrusions 44 and 44 are formed on one side 40 of the belt-like portion 36 on which the locking projection 42 is formed at both end edges in the width direction. The pair of protrusions 44, 44 extend over substantially the entire length of the belt-like part 36, and extend in the width direction of the belt-like part 36 across both protrusions 44, 44. A stop projection 42 is formed.

要するに、帯状部３６の片面４０には、その幅方向の中央部分において彫り込まれた状態で複数の係止突起４２が形成されている。これにより、各係止突起４２の幅方向両側が一対の突条部４４，４４で挟まれており、各係止突起４２の突出先端部が、突条部４４，４４の突出先端面と略同じ高さに抑えられている。   In short, a plurality of locking protrusions 42 are formed on one surface 40 of the belt-like portion 36 in a state of being engraved at the central portion in the width direction. Thereby, both sides in the width direction of each locking projection 42 are sandwiched between the pair of protruding portions 44, 44, and the protruding tip portion of each locking projection 42 is substantially the same as the protruding tip surface of the protruding portions 44, 44. It is held at the same height.

一方、結束バンド１４の挿通係止部３８には、挿通孔４６が形成されていると共に、この挿通孔４６の内部に突出して係止片４８が形成されている。そして、帯状部３６をリング状に湾曲させて先端部を挿通孔４６に挿し入れることにより、帯状部３６の係止突起４２に対して係止片４８が係止されるようになっている。また、係止突起４２が鋸歯形状とされていることにより、係止突起４２に対する係止片４８の係止作用が、挿通孔４６から帯状部３６を引き抜く方向にだけ機能して、帯状部３６を解除不能に締め付けて係止することが出来るようになっている。   On the other hand, an insertion hole 46 is formed in the insertion locking portion 38 of the binding band 14, and a locking piece 48 is formed protruding from the insertion hole 46. Then, the locking piece 48 is locked to the locking protrusion 42 of the band-shaped portion 36 by bending the band-shaped portion 36 in a ring shape and inserting the tip portion into the insertion hole 46. In addition, since the locking projection 42 has a sawtooth shape, the locking action of the locking piece 48 with respect to the locking projection 42 functions only in the direction in which the band-shaped portion 36 is pulled out from the insertion hole 46, and the band-shaped portion 36. Can be tightened and locked so that it cannot be released.

従って、この結束バンド１４の帯状部３６を凹溝１８の底壁２０に形成された一対のバンド挿通穴２２，２２に挿し通して、ワイヤハーネス１２に巻き付けてから、挿通係止部３８に係止させることにより、ワイヤハーネス１２を凹溝１８の底壁２０に対して締め付けて固定することが出来る。   Therefore, the band-like portion 36 of the binding band 14 is inserted into the pair of band insertion holes 22, 22 formed in the bottom wall 20 of the groove 18, wound around the wire harness 12, and then engaged with the insertion locking portion 38. By stopping, the wire harness 12 can be fastened and fixed to the bottom wall 20 of the groove 18.

そして、この作業に際しては、凹溝１８にワイヤハーネス１２を嵌め入れる前又は後に、底壁２０に形成された一対のバンド挿通穴２２，２２に対して、結束バンド１４の帯状部３６を先端側から順次に挿し通すこととなる。その際、帯状部３６の係止突起４２が形成された片面４０は、バンド挿通穴２２，２２の外側の長辺部２４ａ，２４ａと対向している。長辺部２４ａは、外方に膨らんだ凹形状とされていることから、平面形状とされた帯状部３６の片面４０に対して、帯状部３６の幅方向に比して中央部分の方が離隔距離が大きくされる。   In this operation, before or after the wire harness 12 is fitted into the concave groove 18, the band-like portion 36 of the binding band 14 is placed on the distal end side with respect to the pair of band insertion holes 22, 22 formed in the bottom wall 20. Will be inserted sequentially. At that time, the one surface 40 on which the locking projection 42 of the belt-like portion 36 is formed faces the long side portions 24 a and 24 a outside the band insertion holes 22 and 22. Since the long side portion 24a has a concave shape that bulges outward, the central portion of the long side portion 24a is larger than the width direction of the belt-like portion 36 with respect to one side 40 of the belt-like portion 36 that is flat. The separation distance is increased.

それ故、帯状部３６の片面４０に形成された係止突起４２と、バンド挿通穴２２の外側の長辺部２４ａとの対向面間距離が確保され得るのであり、係止突起４２の長辺部２４ａに対する接触が効果的に回避され得る。特に本実施形態では、結束バンド１４の帯状部３６の片面４０において、バンド挿通穴２２，２２への挿通時に長辺部２４ａに接触するおそれがある幅方向両側の端縁部には、一対の突条部４４，４４が形成されていることから、係止突起４２の長辺部２４ａへの接触がより確実に防止され得る。   Therefore, the distance between the opposing surfaces of the locking projections 42 formed on one side 40 of the band-like portion 36 and the long side portion 24a outside the band insertion hole 22 can be secured. Contact with the portion 24a can be effectively avoided. In particular, in the present embodiment, on one side 40 of the band-like portion 36 of the binding band 14, there are a pair of edge portions on both sides in the width direction that may come into contact with the long side portion 24 a when inserted into the band insertion holes 22, 22. Since the protrusions 44 are formed, the contact of the locking protrusion 42 with the long side portion 24a can be prevented more reliably.

これにより、結束バンド１４をバンド挿通穴２２，２２に挿通する際や結束バンド１４を締め付ける際において、係止突起４２がバンド挿通穴２２，２２の開口周縁部や内周面に引っ掛かる不具合を回避することが出来る。そして、結束バンド１４をバンド挿通穴２２，２２に挿通する作業や結束バンド１４を締め付ける作業を効率良く行うことが出来る。また、係止突起４２がバンド挿通穴２２，２２の開口周縁部や内周面に引っ掛かることに起因して潰れてしまう不具合を回避することが出来ることから、係止突起４２の係止片４８への係止作用に基づく結束バンド１４の締付力を一層安定して得ることが可能となる。   Thus, when the binding band 14 is inserted into the band insertion holes 22 and 22 or when the binding band 14 is tightened, the problem that the locking protrusion 42 is caught on the opening peripheral edge or the inner peripheral surface of the band insertion holes 22 and 22 is avoided. I can do it. Then, the operation of inserting the binding band 14 into the band insertion holes 22 and 22 and the operation of tightening the binding band 14 can be performed efficiently. In addition, since it is possible to avoid a problem that the locking projection 42 is crushed due to being caught on the opening peripheral edge or the inner peripheral surface of the band insertion holes 22, 22, the locking piece 48 of the locking projection 42 can be avoided. Accordingly, it is possible to more stably obtain the tightening force of the binding band 14 based on the locking action.

さらに、本実施形態では、バンド挿通穴２２，２２が長穴形状とされていることから、以下に説明するとおり、丸穴形状のバンド挿通穴を採用する場合よりも、更に有利な効果が発揮される。   Furthermore, in this embodiment, since the band insertion holes 22 and 22 are formed in a long hole shape, as described below, a further advantageous effect is exhibited as compared with the case where a round hole shaped band insertion hole is adopted. Is done.

先ず、バンド挿通穴２２，２２の形成スペースを確保し易くなる。即ち、結束バンド１４の帯状部３６を挿通させるためには、バンド挿通穴２２，２２の開口幅を帯状部３６の幅よりも大きくする必要がある。丸穴形状のバンド挿通穴だと、帯状部３６の幅よりも大きな直径の円形穴となる。一方、長穴形状のバンド挿通穴２２だと、幅寸法は同じでも、高さ寸法を小さく出来る。従って、長穴形状のバンド挿通穴２２，２２だと、形成のために必要とされるスペースを小さく抑えることが出来、底壁２０等の部材強度も効果的に確保され得る。   First, it becomes easy to secure a space for forming the band insertion holes 22 and 22. That is, in order to insert the band-like portion 36 of the binding band 14, it is necessary to make the opening width of the band insertion holes 22, 22 larger than the width of the band-like portion 36. In the case of a round hole-shaped band insertion hole, a circular hole having a diameter larger than the width of the belt-like portion 36 is formed. On the other hand, if the band insertion hole 22 has a long hole shape, the height dimension can be reduced even if the width dimension is the same. Therefore, the long hole-shaped band insertion holes 22 and 22 can reduce the space required for formation, and can effectively ensure the strength of the member such as the bottom wall 20.

また、結束バンド１４の挿通状態での表裏反転を防止することが出来る。即ち、円形のバンド挿通穴では挿通された結束バンド１４が回転して反転することが出来るが、バンド挿通穴を長穴形状として、バンド挿通穴２２における一対の長辺部２４，２４の対向距離を結束バンド１４の帯状部３６の幅寸法よりも小さくしたことにより、挿通状態にある結束バンド１４の反転を防止することが出来る。その結果、結束バンド１４の挿通作業を容易に行なうことが可能となる。   In addition, it is possible to prevent the front and back from being reversed when the binding band 14 is inserted. In other words, the binding band 14 inserted through the circular band insertion hole can be rotated and reversed, but the band insertion hole is formed into a long hole shape, and the opposing distance between the pair of long side portions 24 and 24 in the band insertion hole 22 Is made smaller than the width dimension of the band-like portion 36 of the binding band 14, the reversal of the binding band 14 in the inserted state can be prevented. As a result, the binding band 14 can be easily inserted.

さらに、結束バンド１４の締付時における幅方向両端部分への応力集中を軽減することが出来る。即ち、バンド挿通穴２２の内周面の周方向の曲率半径が、円形状の挿通穴の場合に比して長穴形状の方が大きく設定され得る。それ故、結束バンド１４に大きな締付引張力が及ぼされてバンド挿通穴２２の内周面に沿って変形しても、帯状部３６の撓みが小さく抑えられて、応力の著しい集中が回避されることにより、亀裂発生や破断が防止され得る。   Furthermore, stress concentration at both ends in the width direction when the binding band 14 is tightened can be reduced. That is, the radius of curvature in the circumferential direction of the inner peripheral surface of the band insertion hole 22 can be set larger in the case of the elongated hole than in the case of a circular insertion hole. Therefore, even if a large tightening tensile force is exerted on the binding band 14 and the band is deformed along the inner peripheral surface of the band insertion hole 22, the bending of the band-like portion 36 is suppressed to a small extent, and a significant concentration of stress is avoided. By doing so, the occurrence of cracks and breakage can be prevented.

加えて、本実施形態では、バンド挿通穴２２，２２の両側開口のエッジ部が角取面３４，３４とされているので、バンド挿通穴２２，２２の開口周縁部への係止突起４２の引っ掛かりが一層効果的に防止され得る。   In addition, in this embodiment, since the edge portions of both side openings of the band insertion holes 22 and 22 are the chamfered surfaces 34 and 34, the locking projections 42 on the opening peripheral edge portions of the band insertion holes 22 and 22 are formed. The catch can be prevented more effectively.

以上、本発明の一実施形態について詳述したが、本発明はその具体的な記載によって限定されない。例えば、結束バンド用支持部材は、電気接続箱や電気接続箱を車体に装着するブラケット，車体パネル等で構成されていても良い。また、被支持部材は、各種のセンサーケーブルや流体用ホース、更には、電装部品等であっても良い。   As mentioned above, although one Embodiment of this invention was explained in full detail, this invention is not limited by the specific description. For example, the binding band support member may include an electrical junction box, a bracket for mounting the electrical junction box on the vehicle body, a vehicle body panel, and the like. Further, the supported member may be various sensor cables, fluid hoses, and electrical parts.

なお、バンド挿通穴２２，２２の長辺部２４の外方へ膨らむ凹形状は、例示の如き周方向で湾曲した凹状湾曲面に限定されない。例えば、複数の直線を組合せた多角形状で周方向に延びて外方へ膨らむ凹形状をもって長辺部２４を形成することも可能である。   In addition, the concave shape which bulges outward of the long side part 24 of the band insertion holes 22 and 22 is not limited to the concave curved surface curved in the circumferential direction as illustrated. For example, it is also possible to form the long side portion 24 with a concave shape that extends in the circumferential direction and bulges outward in a polygonal shape combining a plurality of straight lines.

また、支持部材に形成された単一のバンド挿通穴に結束バンドを挿通して被支持部材を締付固定する場合にも、本発明を適用することが出来る。例えば、支持部材の端縁部近くに一つのバンド挿通穴を形成し、このバンド挿通穴に挿通した結束バンド１４を、支持部材の端縁部に沿って配索したワイヤーハーネス等の被支持部材に巻き付けて、締付固定する場合にも、本発明を適用して、バンド挿通穴を長辺部が特定形状とされた長穴形状とすることが有効である。   Further, the present invention can also be applied to a case where a supported band is fastened and fixed by inserting a binding band through a single band insertion hole formed in the support member. For example, a supported member such as a wire harness in which one band insertion hole is formed near the edge of the support member, and the binding band 14 inserted through the band insertion hole is routed along the edge of the support member. It is also effective to apply the present invention to the band insertion hole in the shape of a long hole with a long side portion having a specific shape even when it is wound around and fastened.
