Description

【０００１】
【発明の属する技術分野】
本発明は、ケーブルに取り付けられてケーブルを保護するためのブッシングに関するものである。
【０００２】
【従来の技術】
近年、オフィスビルなどにおいて、床下スラブと部屋の床との間に配線ケーブルを引き回すための配線スペースを設け、室内のレイアウトに応じて床配線を自在に行うことができるようにした床配線システム（所謂フリーアクセスフロア）が提供されており、床下から床上へケーブルを引き出す際に、床下から引き出されるケーブルの部位を保護するために、図１４に示すような構造を有するブッシングが提供されている。
【０００３】
このブッシング１は合成樹脂成型品からなり、筒状であって軸方向の一面に細径の差込部２ａが突設された胴部２と、上面が略正方形状であって差込部２ａの上端部に設けられた鍔部３とで構成され、鍔部３の略中央には胴部２に設けた貫通孔２ｂと連通するケーブル挿通孔３ａが穿設されている。このブッシング１は、貫通孔２ｂとケーブル挿通孔３ａとにケーブルを通し、鍔部３を床上側、胴部２を床下側として、床面に固定される取付板を鍔部３と胴部２との間に挟んだ状態で床面に取り付けられ、床下から引き出されるケーブルの部位を保護するものである。
【０００４】
胴部２は、軸方向において略２等分に分割され、ヒンジ部６を介して互いに連結された２つの半割体４，５により構成され、両半割体４，５の接合面には貫通孔２ｂを構成する凹所４ａ，５ａがそれぞれ形成されている。ヒンジ部６は各半割体４，５の軸方向に沿う一側縁から連続一体に形成されており、薄肉に形成され、屈曲性を良くしているので、ヒンジ部６を屈曲させることによって２つの半割体４，５を開閉させることができる。
【０００５】
一方の半割体４には、ヒンジ部６が形成された側と反対側の側縁から、他方の半割体５に向かって突出する係止フック７が連続一体に形成されており、この係止フック７には外側（胴部２の中心と反対側）に向かって突出する係止爪８が突設されている。また、他方の半割体５には、ヒンジ部６が形成された側と反対側の側縁に筒状の係止部１０が一体に形成されている。係止部１０は、係止爪８が突設された弾性係止片７の面と対向して配置される係止片１０ａと、係止片１０ａの上下辺から連続一体に延設され係止片１０ａの上下辺と半割体４とを連結する連結片１０ｂ，１０ｂとで構成され、係止片１０ａと連結片１０ｂ，１０ｂと半割体４の側縁とで囲まれる空間により、係止部１０を貫通する貫通孔９が形成される。
【０００６】
ここで、このブッシング１をケーブル（図示せず）に取り付ける際は、鍔部３に設けたケーブル挿通孔３ａにケーブルの一端を通し、ケーブルの所望の位置までブッシング１を移動させた後、ヒンジ部６を屈曲させて２つの半割体４，５を閉じ、半割体４の係止フック７を半割体５の貫通孔９内に挿入して、係止フック７に設けた係止爪８を貫通孔９の開口縁（すなわち係止片１０ａの側縁）と係止させることにより、２つの半割体４，５でケーブルを挟持して、ブッシング１をケーブルに取り付けている。
【０００７】
【発明が解決しようとする課題】
上述したブッシング１では、一体に形成された鍔部３にケーブル挿通孔３ａを形成しているので、ケーブルの何れかの端をブッシング１のケーブル挿通孔３ａに通した後、ケーブルの所望の位置までブッシング１を移動させねばならず、ケーブルの途中にブッシング１を直接取り付けることができないため、ブッシング１の着脱作業がやりにくいという問題があった。
【０００８】
本発明は上記問題点に鑑みて為されたものであり、その目的とするところは、着脱作業の作業性を向上させたブッシングを提供することにある。
【０００９】
【課題を解決するための手段】
上記目的を達成するために、請求項１の発明では、筒状であって軸方向の一面に細径の差込部が設けられた胴部と、差込部の先端部に設けられ胴部を貫通する貫通孔に連通するケーブル挿通孔が形成された鍔部とを備え、差込部を被取付部材に形成された溝内に挿入した状態で被取付部材に取り付けられるブッシングにおいて、胴部及び鍔部は軸方向において２分割された２つの半割体からなり、２つの半割体を連結する屈曲性を備えたヒンジ部を設け、２つの半割体の内、一方の半割体に他方の半割体に向かって突出する弾性係止片を設けるとともに、他方の半割体に弾性係止片が挿入される貫通孔が形成された筒状の係止部を設け、弾性係止片の先端に設けた係止爪と貫通孔の開口縁とを係止させることによって２つの半割体を結合させており、貫通孔の内面であって弾性係止片の係止爪が対向する部位に、２つの半割体が開いた状態と閉じた状態との間の途中の状態で、弾性係止片の係止爪が係止する係止凹所を設けたことを特徴とする。また請求項２の発明は、筒状であって軸方向の一面に細径の差込部が設けられた胴部と、差込部の先端部に設けられ胴部を貫通する貫通孔に連通するケーブル挿通孔が形成された鍔部とを備え、差込部を被取付部材に形成された溝内に挿入した状態で被取付部材に取り付けられるブッシングにおいて、胴部及び鍔部は軸方向において２分割された２つの半割体からなり、２つの半割体を連結する屈曲性を備えたヒンジ部を設け、２つの半割体の内、一方の半割体に他方の半割体に向かって突出する弾性係止片を設けるとともに、他方の半割体に弾性係止片が挿入される貫通孔が形成された筒状の係止部を設け、弾性係止片に、２つの半割体が開いた状態と閉じた状態との間の途中の状態で貫通孔の開口縁と係止する第１の係止爪と、２つの半割体が閉じた状態で貫通孔の開口縁と係止する第２の係止爪とを、弾性係止片の突出方向に並べて形成したことを特徴とする。請求項１、２の発明は上記構成を採用しており、胴部及び鍔部が軸方向において２分割されており、ヒンジ部を屈曲させ、２つの半割体でケーブルを挟み込むことによって、ブッシングをケーブルに取り付けているので、ケーブルの途中でもブッシングを取り付けることができ、従来のブッシングのようにケーブル挿通孔にケーブルの一端を通した後、ケーブルの所望の位置までブッシングをずらして、ブッシングを固定する必要はなく、ブッシングの着脱作業の作業性を向上させることができる。しかも、２つの半割体が開いた状態と閉じた状態との間で弾性係止片と貫通孔とを２段階で係止させているので、２つの半割体を閉じてケーブルに固定する前に、ブッシングをケーブルに仮止めすることができるから、ブッシングをケーブルに仮止めした状態でブッシングの位置を微調整した後にケーブルに固定することができる。
【００１１】
請求項３の発明では、請求項１又は２の発明において、上記係止部は、弾性係止片に対向して配置される係止片と、係止片の両側縁を他方の半割体に連結する連結片とで構成され、連結片における一方の半割体と反対側の部位に、一方の半割体から遠ざかるにつれて筒部の中心側に近付く向きに傾斜する傾斜面を形成したことを特徴とし、両半割体の結合時には貫通孔から弾性係止片の先端が突出し、弾性係止片に設けた係止爪が貫通孔の開口縁と係止しているが、連結片における一方の半割体と反対側の部位には、一方の半割体から遠ざかるにつれて筒部の中心側に近付く向きに傾斜する傾斜面が形成されているので、両半割体の結合状態を解除する際に貫通孔から突出する弾性係止片の先端部分を指で押圧しやすくなり、ブッシングの取り外し作業を容易に行え、ブッシングの着脱作業の作業性が向上する。
【００１２】
請求項４の発明では、請求項１又は２の発明において、２つに分割された鍔部の内、一方の鍔部における他方の鍔部との接合面に、他方の鍔部に向かって突出する突起を設けるとともに、他方の鍔部における一方の鍔部との接合面に前記突起が嵌合する凹所を設けて成ることを特徴とし、突起と凹所とを嵌合させることによって、鍔部の接合面にできる隙間を無くし、製品の見栄えを良くできる。
【００１４】
【発明の実施の形態】
以下に本発明の実施の形態を図面を参照して説明する。
【００１５】
先ず本発明に係るブッシングの基本構成を図１乃至図９を参照して説明する。このブッシング１は合成樹脂成型品からなり、筒状であって軸方向の一面に細径の差込部２ａが突設された胴部２と、上面が略正方形状であって差込部２ａの上端部に設けられた鍔部３とで構成され、鍔部３には胴部２に設けた貫通孔２ｂと連通するケーブル挿通孔３ａが穿設されている。
【００１６】
図９はブッシング１の使用状態を説明する説明図である。このブッシング１は所謂フリーアクセスフロアに用いられ、床下に配置される配線器具３３に着脱自在に接続されるプラグ３１が一端に接続されるとともに、床上に配置されるコンセントなどの配線器具３２が他端に接続されたケーブル３０を床下から床上に引き出すために用いられる。フリーアクセスフロアの床材４０には床面よりも一段低くなった凹部４１が形成され、凹部４１の底には床材４０を貫通する貫通孔４２が穿設されており、この貫通孔４２は一辺にブッシング１の差込部２ａを挿入するための溝４３ａが形成された取付板４３によって遮蔽される。そして、ケーブル３０に取り付けたブッシング１を床面に固定する際は、先ずブッシング１の差込部２ａを取付板４３の溝４３ａ内に挿入し、胴部２と鍔部３との間で取付板４３を挟持することによって、ブッシング１を取付板４３に取り付けた後、取付板４３を床材４０の表面に設けた凹部４１内に固定することによって、ブッシング１が床面に固定され、床下から引き出されるケーブル３０の部位をブッシング１で保護している。
【００１７】
胴部２は、軸方向において略２等分に分割され、ヒンジ部６を介して互いに連結された２つの半割体４，５により構成され、両半割体４，５の接合面には貫通孔２ｂを構成する凹所４ａ，５ａがそれぞれ形成されている。ヒンジ部６は各半割体４，５の軸方向に沿う一側縁から連続一体に形成されており、薄肉に形成され、屈曲性を良くしているので、ヒンジ部６を屈曲させることによって２つの半割体４，５を開閉させることができる。
【００１８】
ここで、一方の半割体４には、ヒンジ部６が形成された側と反対側の側縁から、他方の半割体５に向かって突出する係止フック（弾性係止片）７が連続一体に形成されており、この係止フック７には外側（胴部２の中心と反対側）に向かって突出する係止爪８が突設されている。また、他方の半割体５には、ヒンジ部６が形成された側と反対側の側縁に筒状の係止部１０が一体に形成されている。
【００１９】
係止部１０は、係止爪８が突設された弾性係止片７の面と対向して配置される係止片１０ａと、係止片１０ａの上下辺から連続一体に延設され係止片１０ａの上下辺と半割体４とを連結する連結片１０ｂ，１０ｂとで構成され、係止片１０ａと連結片１０ｂ，１０ｂと半割体４の側縁とで囲まれる空間により、係止部１０を貫通する貫通孔９が形成される。また、係止片１０ａにおける一方の半割体４側の開口縁には、内側（胴部２の中心側）に向かって突出し、係止フック７に設けた係止爪８と係止して係止フック７を仮止めするための係止凸部１０ｄが突設されている（図６参照）。
【００２０】
また、鍔部３は、胴部２と同様に、軸方向において略２等分に分割された２つの半割体１１，１２からなり、各半割体１１，１２はそれぞれ胴部２を構成する半割体４，５と連続一体に形成されている。２つの半割体１１，１２は上面が長方形状であって、接合面の略中央にはケーブル挿通孔３ａを構成する半円形の切欠き部１１ａ，１２ａがそれぞれ形成されている。
【００２１】
ここで、このブッシング１をケーブルに取り付ける際は、図８（ａ）に示すように、ケーブル３０を半割体５の凹所５ａ内に配置し、ヒンジ部６を屈曲させて、半割体４を半割体５側に押し込むと、半割体４の係止フック７が半割体５の貫通孔９内に挿入され、係止フック７の係止爪８が半割体５の係止片１０ａに設けた係止凸部１０ｄと係止して、半割体５が半割体４に仮固定され、ブッシング１がケーブル３０に仮固定される。
【００２２】
そして、ブッシング１をケーブル３０に仮固定した状態で、ブッシング１の位置を微調整した後、半割体４を半割体５側にさらに押し込むと、図８（ｂ）に示すように、半割体４の係止フック７に設けた係止爪８が半割体５の係止片１０ａを乗り越えて、貫通孔９の開口縁（すなわち係止片１０ａの端縁）と係止することにより、２つの半割体４，５が結合され、ブッシング１がケーブル３０に固定される。
【００２３】
このように、ブッシング１は、胴部２及び鍔部３が両方共に軸方向において略２等分に分割されており、半割体４，１１と半割体５，１２との間でケーブル３０を挟み込むことによってケーブル３０に保持されるので、ケーブル３０の途中でもブッシング１を取り付けることができ、従来例で説明したブッシング１のように、鍔部３に設けたケーブル挿通孔３ａにケーブルの一端を通した後、ケーブルの所望の位置までブッシング１を移動させて、ブッシング１を固定する必要はなく、ブッシング１の取付作業を容易に行うことができる。
【００２４】
ここで、一方の半割体４の接合面には、他方の半割体５に向かって突出する位置決め用の突条１３が形成され、他方の半割体５の接合面には、突条１３が嵌合する凹所１４が形成されており、２つの半割体４，５を結合すると、突条１３と凹所１４とが嵌合するので、両半割体４，５のがたつきを無くすことができる。また、鍔部３を構成する２つの半割体１１，１２の内、一方の半割体１２の接合面には、もう一方の半割体１１に向かって突出する突出片（突起）１５，１５が突設され、他方の半割体１１の接合面には突出片１５，１５が嵌合する嵌合凹所１６，１６が形成されている。而して、両半割体１１，１２の接合時には突出片１５が嵌合凹所１６と嵌合し、両半割体１１，１２の間の隙間が突出片１５によって塞がれるので、外観の見栄えを良くできる。また更に、各半割体４，５の凹所４ａ，５ａには内側に向かって突出するリブ４ｂ，５ｂがそれぞれ突設されており、ブッシング１をケーブルに取り付ける際に、凹所４ａ，５ａに設けたリブ４ｂ，５ｂがケーブルの表面と接触して、ケーブルの滑り止めを行うことができる。
【００２５】
一方、ブッシング１をケーブル３０から取り外す際は、貫通孔９の開口縁から突出する係止フック７の先端部を内側（すなわち胴部２の中心に近い側）に押圧すると、係止爪８と貫通孔９の開口縁（係止片１０ａの端縁）との係止状態が解除され、さらに係止フック７の先端部を半割体４側に押圧すると、半割体４，５が両側に開き、ブッシング１をケーブル３０から取り外すことができる。
【００２６】
ここで、連結片１０ｂにおける一方の半割体４と反対側の部位には、一方の半割体４から遠ざかるにつれて筒部２の中心側に近付く向きに傾斜するテーパ面（傾斜面）１０ｃが形成されているので、ブッシング１を取り外す際に、指が胴部２の近くまで入り込み、したがって係止フック７の先端部を内側へ押圧しやすくなり、ブッシング１の取り外し作業を容易に行える。
【００２７】
（実施形態１）
本発明の実施形態１を図１０及び図１１を参照して説明する。基本構成で説明したブッシング１では、半割体５の係止片１０ａにおける半割体４側の開口縁に係止凸部１０ｄを設け、半割体４の係止フック７に設けた係止爪８を係止凸部１０ｄと係止させることによって、半割体４，５を仮止めしているが、本実施形態のブッシング１では、半割体５の係止片１０ａに係止凸部１０ｄを設ける代わりに、半割体４の係止フック７に、外側に向かってそれぞれ突出する係止爪８ａ，８ｂを係止フック７の突出方向に沿って２個並べて突設している。尚、係止爪８ａ，８ｂ以外の構成は基本構成で説明したブッシングと同様であるので、同一の構成要素には同一の符号を付して、その説明を省略する。
【００２８】
ここで、このブッシング１をケーブルに取り付ける際は、図１１（ａ）に示すように、ケーブル３０を半割体５の凹所５ａ内に配置した状態で、ヒンジ部６を屈曲させて、半割体４を半割体５側に押し込むと、半割体４の係止フック７に設けた２個の係止爪８ａ，８ｂの内、先端側の係止爪８ａ（第１の係止爪）が半割体５の係止片１０ａと係止して、半割体５が半割体４に仮固定され、ブッシング１がケーブル３０に仮固定される。
【００２９】
そして、ブッシング１をケーブル３０に仮固定した状態で、ブッシング１の位置を微調整した後、半割体５を半割体４側へさらに押し込むと、図１１（ｂ）に示すように、基部側の係止爪８ｂ（第２の係止爪）が半割体５の係止片１０ａと係止して、２つの半割体４，５が結合され、ブッシング１がケーブル３０に固定される。
【００３０】
このように、本実施形態のブッシング１では、２つの半割体４，５が開いた状態と閉じた状態との間で、係止フック７が係止片１０ａと２段階に係止するような形状に係止フック７の形状を形成しているので、ブッシング１をケーブルに仮固定した状態でブッシング１の位置を微調整した後、ブッシング１をケーブルに固定することができるから、ブッシング１の取付位置の調整を容易に行うことができる。
【００３１】
（実施形態２）
本発明の実施形態２を図１２及び図１３を参照して説明する。基本構成で説明したブッシング１では、半割体５の係止片１０ａにおける半割体４側の開口縁に係止凸部１０ｄを設け、半割体４の係止フック７に設けた係止爪８を係止凸部１０ｄと係止させることによって、半割体４，５を仮止めしているが、本実施形態のブッシング１では、半割体５の係止片１０ａに係止凸部１０ｄを設ける代わりに、係止片１０ａの中間部に係止爪８と嵌合する係止凹所１０ｅ（被係止部）を設けている。尚、係止凹所１０ｅ以外の構成は基本構成で説明したブッシングと同様であるので、同一の構成要素には同一の符号を付して、その説明を省略する。
【００３２】
ここで、このブッシング１をケーブルに取り付ける際は、図１３（ａ）に示すように、ケーブル３０を半割体５の凹所５ａ内に配置した状態で、ヒンジ部６を屈曲させて、半割体４を半割体５側に押し込むと、半割体４の係止フック７に設けた係止爪８が、半割体５の係止片１０ａに設けた係止凹所１０ｅと係止して、半割体５が半割体４に仮固定され、ブッシング１がケーブル３０に仮固定される。そして、ブッシング１をケーブル３０に仮固定した状態で、ブッシング１の位置を微調整した後、半割体４を半割体５側にさらに押し込むと、図１３（ｂ）に示すように、係止フック７の係止爪８が半割体５の係止片１０ａを乗り越えて、係止片１０ａの端縁と係止することにより、２つの半割体４，５が結合され、ブッシング１がケーブル３０に取り付けられる。
【００３３】
このように、本実施形態のブッシング１では、２つの半割体４，５が開いた状態と閉じた状態との間で、係止フック７が係止片１０ａと２段階に係止するような形状に係止片１０ａの形状を形成しているので、ブッシング１をケーブルに仮固定した状態でブッシング１の位置を微調整した後、ブッシング１をケーブルに固定することができるから、ブッシング１の取付位置の調整を容易に行うことができる。
【００３４】
【発明の効果】
上述のように、請求項１の発明は、筒状であって軸方向の一面に細径の差込部が設けられた胴部と、差込部の先端部に設けられ胴部を貫通する貫通孔に連通するケーブル挿通孔が形成された鍔部とを備え、差込部を被取付部材に形成された溝内に挿入した状態で被取付部材に取り付けられるブッシングにおいて、胴部及び鍔部は軸方向において２分割された２つの半割体からなり、２つの半割体を連結する屈曲性を備えたヒンジ部を設け、２つの半割体の内、一方の半割体に他方の半割体に向かって突出する弾性係止片を設けるとともに、他方の半割体に弾性係止片が挿入される貫通孔が形成された筒状の係止部を設け、弾性係止片の先端に設けた係止爪と貫通孔の開口縁とを係止させることによって２つの半割体を結合させており、貫通孔の内面であって弾性係止片の係止爪が対向する部位に、２つの半割体が開いた状態と閉じた状態との間の途中の状態で、弾性係止片の係止爪が係止する係止凹所を設けたことを特徴とする。また、請求項２の発明は、筒状であって軸方向の一面に細径の差込部が設けられた胴部と、差込部の先端部に設けられ胴部を貫通する貫通孔に連通するケーブル挿通孔が形成された鍔部とを備え、差込部を被取付部材に形成された溝内に挿入した状態で被取付部材に取り付けられるブッシングにおいて、胴部及び鍔部は軸方向において２分割された２つの半割体からなり、２つの半割体を連結する屈曲性を備えたヒンジ部を設け、２つの半割体の内、一方の半割体に他方の半割体に向かって突出する弾性係止片を設けるとともに、他方の半割体に弾性係止片が挿入される貫通孔が形成された筒状の係止部を設け、弾性係止片に、２つの半割体が開いた状態と閉じた状態との間の途中の状態で貫通孔の開口縁と係止する第１の係止爪と、２つの半割体が閉じた状態で貫通孔の開口縁と係止する第２の係止爪とを、弾性係止片の突出方向に並べて形成したことを特徴とする。請求項１、２の発明は上記構成を採用しており、胴部及び鍔部が軸方向において２分割されており、ヒンジ部を屈曲させ、２つの半割体でケーブルを挟み込むことによって、ブッシングをケーブルに取り付けているので、ケーブルの途中でもブッシングを取り付けることができ、従来のブッシングのようにケーブル挿通孔にケーブルの一端を通した後、ケーブルの所望の位置までブッシングをずらして、ブッシングを固定する必要はなく、ブッシングの着脱作業の作業性が向上するという効果がある。しかも、２つの半割体が開いた状態と閉じた状態との間で弾性係止片と貫通孔とを２段階で係止させているので、２つの半割体を閉じてケーブルに固定する前に、ブッシングをケーブルに仮止めすることができるから、ブッシングをケーブルに仮止めした状態でブッシングの位置を微調整した後にケーブルに固定することができる。
【００３６】
請求項３の発明は、請求項１又は２の発明において、上記係止部は、弾性係止片に対向して配置される係止片と、係止片の両側縁を他方の半割体に連結する連結片とで構成され、連結片における一方の半割体と反対側の部位に、一方の半割体から遠ざかるにつれて筒部の中心側に近付く向きに傾斜する傾斜面を形成したことを特徴とし、両半割体の結合時には貫通孔から弾性係止片の先端が突出し、弾性係止片に設けた係止爪が貫通孔の開口縁と係止しているが、連結片における一方の半割体と反対側の部位には、一方の半割体から遠ざかるにつれて筒部の中心側に近付く向きに傾斜する傾斜面が形成されているので、両半割体の結合状態を解除する際に貫通孔から突出する弾性係止片の先端部分を指で押圧しやすくなり、ブッシングの取り外し作業を容易に行え、ブッシングの着脱作業の作業性が向上するという効果がある。
【００３７】
請求項４の発明は、請求項１又は２の発明において、２つに分割された鍔部の内、一方の鍔部における他方の鍔部との接合面に、他方の鍔部に向かって突出する突起を設けるとともに、他方の鍔部における一方の鍔部との接合面に前記突起が嵌合する凹所を設けて成ることを特徴とし、突起と凹所とを嵌合させることによって、鍔部の接合面にできる隙間を無くし、製品の見栄えを良くできるという効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a bushing attached to a cable for protecting the cable.
[0002]
[Prior art]
In recent years, floor wiring systems (such as office buildings) have been provided with a wiring space for routing the wiring cable between the floor slab and the floor of the room so that floor wiring can be performed freely according to the indoor layout ( A so-called free access floor is provided, and a bushing having a structure as shown in FIG. 14 is provided in order to protect a portion of the cable drawn from under the floor when the cable is drawn from the under floor to the floor.
[0003]
The bushing 1 is made of a synthetic resin molded product, and has a cylindrical shape with a cylindrical portion 2 having a small-diameter insertion portion 2a protruding on one surface in the axial direction, and an upper surface having a substantially square shape, and the insertion portion 2a. A cable insertion hole 3 a communicating with a through hole 2 b provided in the trunk portion 2 is formed in the approximate center of the flange portion 3. The bushing 1 has a cable passing through the through hole 2b and the cable insertion hole 3a, with the flange 3 as the floor upper side and the body 2 as the floor lower, and the mounting plate fixed to the floor surface as the flange 3 and the body 2. It is attached to the floor surface in a state of being sandwiched between and the cable portion that is drawn out from under the floor is protected.
[0004]
The body part 2 is divided into two substantially equal parts in the axial direction and is composed of two halves 4 and 5 connected to each other via a hinge part 6. Recesses 4a and 5a constituting the through hole 2b are respectively formed. The hinge portion 6 is formed integrally from one side edge along the axial direction of each of the halves 4 and 5, and is formed thin and has good flexibility. Therefore, by bending the hinge portion 6, The two halves 4 and 5 can be opened and closed.
[0005]
One half 4 is integrally formed with a locking hook 7 projecting from the side edge opposite to the side where the hinge 6 is formed toward the other half 5.
