【発明の属する技術分野】
本発明は、例えば第一部材と第二部材との基端部同志を枢着して、双方が重合した閉塞状態から第一部材，第二部材のいずれか一方を所定開放角度まで回動した開放状態に開閉できるヒンジ装置であって、この基端部枢着部に撮影映像を取り組むことができるカメラ部を回動自在に組み込むヒンジ装置並びにこのヒンジ装置を用いた携帯電話，パソコンなどの電子機器に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
例えば、ノート型と称されるパソコンやワープロ或いは開閉式の携帯電話は、操作部を備えた本体部に対してディスプレイ部を備えた開閉蓋部（重合部）がヒンジ装置を介して起伏開閉自在に設けられているが、この重合部を本体部に伏した閉塞重合状態でこの重合部が勝手に開いてしまうことがないように、閉塞状態を維持する重合保持機能をヒンジ装置に設けている。
【０００３】
即ち、例えばヒンジ装置の回動軸部を軸に互いに相対回動自在に設けられる本体部若しくは重合部の回動と共に回動するカム部と、重合部若しくは本体部の回動と共に回動するカム係合部とを有し、閉塞重合状態となるとき、このカム部に設けた凸部とカム係合部に設けた凹部とが凹凸係合することでこの重合状態が係合保持されるように構成し、また、開放回動時に再び凹凸係合し、所定回動位置が係合保持されるように構成している。
【０００４】
また、一方このようなパソコンや携帯電話などの電子機器においては、デジタルカメラのように写した画像を取り込みデータ保存したり、ディスプレイ部に表示したり、データ送信したりできるカメラ部を備えたものが好評である。このカメラ部は、例えばＣＣＤカメラを組み込んだカメラ部を設け、これを配線するものであるが、これまでは本体部あるいは重合部に単に取り付けていたにすぎないため、カメラ部の向きを自在に変えることはできない。
【０００５】
即ち、これまでのカメラと同様ＣＣＤカメラを被写体に向けてシャッタースイッチ（画像記録スイッチ）を操作して撮影する従来通りの固定観念に基づいた構成であるため、例えば重合部の背面にＣＣＤカメラを設けた場合は、相対する被写体を撮る時は、重合部正面のディスプレイ部に写し出されている撮影画像を確認しながらシャッタースイッチを押すことができ便利であるが、自身を撮影する時は、表裏反転させて持ち変え、カメラ部を自身の方にむけるため、ディスプレイ部を見ながら撮影することはできない。
【０００６】
そこで本発明では、このような現状を打破すべく、このカメラ部の向きを向こう側へも手前側へも自在に反転回動できるようにすれば、極めて使い易く、使用用途がひろがり、商品価値が飛躍的に向上することに着眼した。
【０００７】
本発明は、このような技術的課題に取り組む中で、更に開閉回動枢着部にカメラ部を配置すれば、カメラ部の向きを向こう側（背面側）へも手前側（正面側）にも自在に向けて例えば前述したような撮影が常にディスプレイ部に写し出しながら可能であることに着眼すると共に、開閉のためのヒンジ装置に組み込みできる構成とすることで、これを容易に実現できると共に、製作も容易で量産性に秀れた画期的な電子機器を実現できることを見出した。
【０００８】
即ち、本発明は、カメラ部を枢着部に回動自在に組み込むことが実現できるカメラ回動軸部付の開閉ヒンジ装置を実現することで、第一部材と第二部材とを従来通り重合保持機能を発揮させつつ開閉回動できる上、この開閉回動に支障なくカメラ部を回動自在に組み込むことが容易に実現でき、背面側にも正面側にも自在にカメラ向きを変更でき、しかも、このカメラ部をこれまでの開閉ヒンジ装置を利用して開閉枢着部分に容易に回動自在に配設することができる画期的なヒンジ装置並びにヒンジ装置を用いた電子機器を提供することを目的としている。
【０００９】
【課題を解決するための手段】

【００１１】
また、前記反対側の第一取付部５には前記回動軸部６を設けずに、前記カメラ軸受部２１を設け、この反対側の第一取付部５と対向する前記反対側の第二取付部７に設けた前記カメラ回動軸部２０を前記カメラ軸受部２１に回動自在に係合し、前記一方側の第一取付部５に設けた前記回動軸部６と連動せず別離状態にして略同一軸線上に設けた前記カメラ回動軸部２０に前記カメラ部２３を設けて、前記左右の第一取付部５間に配設した前記カメラ部２３を前記カメラ回動軸部２０を軸に自転回動自在に設けたことを特徴とする請求項１記載のヒンジ装置に係るものである。

【００１３】
また、前記反対側の第一取付部５若しくは第二取付部７に前記カメラ回動軸部２０と共に回動する凸部２４Ａを有するカメラ回動用カム部２４若しくは凹部２５Ａを有するカメラ回動用カム係合部２５を設け、前記カメラ軸受部２１と共に回動する凹部２５Ａを有するカメラ回動用カム係合部２５若しくは凸部２４Ａを有するカメラ回動用カム部２４を前記反対側の第二取付部７若しくは第一取付部５に設け、この相対回動することで凹凸係合するカメラ回動用カム係合部２５，カメラ回動用カム部２４の少なくとも一方を係合離反方向にスライド移動自在に設けると共に、このカメラ回動用カム係合部２５，カメラ回動用カム部２４の少なくとも一方が係脱するに際して離反方向に移動した際係合方向に付勢するカメラ回動用係合付勢機構２６を設けて、前記カメラ部２３を自転回動した所定回動位置でこのカメラ回動用カム係合部２５とカメラ回動用カム部２４とが凹凸係合若しくは係合途中となり、前記カメラ回動用係合付勢機構２６によりこの係合が保持されるあるいは係合付勢されるように構成し、このカメラ回動用カム係合部２５，カメラ回動用カム部２４のいずれか一方を前記カメラ回動用係合付勢機構２６に抗して離反方向に移動させつつ回動させることで前記カメラ回動用カム係合部２５に対してカメラ回動用カム部２４を係脱させ、カメラ部２３を自転回動するように構成したことを特徴とする請求項１〜３のいずれか１項に記載のヒンジ装置に係るものである。
【００１４】
また、操作部を設けた本体部と、ディスプレイ部を設けた重合部とを、前記操作部を操作しない時にはこの操作部を覆うように重合配設し、この重合した状態から前記重合部を相対的に回動して操作部を露出させることができるように前記本体部と前記重合部とを回動自在に連結するヒンジ装置を有し、このヒンジ装置には、前記本体部を前記第一部材２若しくは第二部材４とし、前記重合部を前記第二部材４若しくは第一部材２とした前記請求項１〜４のいずれか１項に記載のヒンジ装置を用いたことを特徴とするヒンジ装置を用いた電子機器に係るものである。
【００１５】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して簡単に説明する。
【００１６】
例えば、第一部材２に対して第二部材４を相対回動して重合状態とすると、回動軸部６を軸として係合付勢機構１１により押圧付勢されつつカム部９とカム係合部１０とは相対回動して、例えばカム部９の凸部９Ａとカム係合部１０の凹部１０Ａとは互いに凹凸係合若しくは係合途中となる。
【００１７】
従って、係合付勢機構１１による押圧付勢とこの凹凸の吸い込み力によるカム係合付勢によって重合方向へ回動付勢（閉塞付勢）が生じ、この係合付勢機構１１に付勢された凹凸係合によって、重合状態が係合保持される。
【００１８】
このように、重合閉塞時に限られるものではないが、カム部９とカム係合部１０とが凹凸係合することで、所定の回動位置がこのカム係合によって位置決め保持あるいは付勢保持される。
【００１９】
一方、本発明ではこのような開閉回動が枢着部の片側（本ヒンジ装置の片側）に配設した回動軸部６と軸受部８とにより行なわれ、反対側に設けたカメラ回動軸部２０とカメラ軸受部２１とによりカメラ部２３が少なくとも１８０度反転回動することとなる。
【００２０】
即ち、枢着部の片側には開閉回動用のヒンジ部が構成され、反対側にはカメラ回動用の回動構造が構成され、この間にカメラ部２３が少なくとも１８０度反転回動自在に組み込まれ、第一部材２に対する第二部材４の開閉回動に支障なく、この枢着部にカメラ部２３が回動自在に設けられ、この開閉回動を行なう本ヒンジ装置にカメラ回動軸部２０とカメラ軸受部２１が設けられることで枢着部にカメラ部２３を回動自在に容易に設けることができることとなる。
【００２１】
言い換えると、開閉回動を行なうヒンジ装置を利用することでカメラ部２３をこの第一部材２と第二部材４との枢着部に組み込むことが容易に実現でき、また容易に製作可能で量産性に秀れることとなり、枢着部にカメラ部２３を回動自在に設けることで、容易にカメラ部２３を背面側にも正面側にも向けられ、例えば相対する被写体であっても、被写体が自身の顔であっても、常にディスプレイ部を正面に向けてここに写しだされる撮影映像を確認しながら、シャッター操作可能となる画期的なカメラ付携帯電話やモバイル等の電子機器を実現できることとなる。
【００２２】
しかも、本ヒンジ装置の片側に従来同様の開閉回動を行なうヒンジ部を配しつつ、反対側にカメラ回動構造を設け、この間にカメラ部２３を回動自在に配設できるため、本ヒンジ装置を用いて第一部材２と第二部材４とを枢着することで前記画期的な電子機器を容易に実現でき、製作容易で量産性に秀れる。即ち、カメラ部２３の前記位置への組み込みが極めて簡単に組み付け製作でき、前記画期的回動機能付カメラを備えた電子機器を量産し得る極めて画期的なヒンジ装置並びにヒンジ装置を用いた電子機器となる。
【００２３】
【実施例】
本発明の具体的な実施例について図面に基づいて説明する。
【００２４】
本実施例は、図１に示すように、起伏開閉回動型の携帯電話に適用した場合のもので、キー操作部１を備えた本体部を第一部材２とし、ディスプレイ部３（ＬＣＤ）を備えた開閉蓋部（重合部）を第二部材４とし、この第一部材２と第二部材４とが重合した閉塞状態から第二部材４を立ち上げて開放状態（使用位置）とすることができる枢着構造に本発明のヒンジ装置を適用している（本実施例では左右両側に設けた構成とせず、本ヒンジ装置の左側にのみこの開閉ヒンジ部を設けた構成としている。）。
【００２５】
本実施例では、第一部材２（本体部）にコ字状の連結部（連結金具）５Ａを設け、その先端部を第一取付部５として左右に対向状態に設けている。一方、第二部材４（重合部）の左右に垂設した筒状部を第二取付部７として左右に対向状態に設け、この左右の夫々の第二取付部７がその内側の前記左右の第一取付部５と夫々対向状態に配されるように構成している。
【００２６】
先ずは、この片側（左側）の第一取付部５と第二取付部７とに設けられる開閉回動のための開閉ヒンジ部について説明し、その後反対側（右側）の第一取付部５と第二取付部７とに設けるカメラ回動構造について説明し、そしてその間に設けられるカメラ部２３について説明することで本実施例のヒンジ装置を説明する。
【００２７】
片側の第一取付部５の取付孔に回り止め状態に回動軸部６を挿通固定して、第一部材２側にこの第一取付部５を介して回動軸部６を設ける。また、片側の筒状の第二取付部７にこの回動軸部６を回動自在に係合する軸受部８を設ける。
【００２８】
本実施例では、この軸受部８は、後述する第二取付部７に回り止め固定するカム部９の挿通孔に前記回動軸部６を回動自在に挿通する構成とし、この第二取付部７に設けたカム部９自体を軸受部８としている。
【００２９】
また、本実施例では、回動軸部６に回動軸部６と共に回動する凹部１０Ａを有するカム係合部１０を第一取付部５に設けている。
【００３０】
具体的には、本実施例では第一取付部５の片側表面に凹部１０Ａを形成し、この第一取付部５自体をカム係合部１０としている。
【００３１】
一方、軸受部８と共に回動する凸部９Ａを有するカム部９を第二取付部７に設けている。
【００３２】
具体的には、前述のように第二取付部７に回り止め状態に係止し且つ回動軸部６に沿って移動自在となるカム部９を第二取付部７の係止取付部１２に係止、このカム部９の挿通孔に回動軸部６を挿通し、このカム部９自体を軸受部８としている。
【００３３】
また、この筒状の第二取付部７内に係合付勢機構１１としてバネを設け、カム部９とカム係合部１０とが回動軸部６を軸に相対的に回動して凹凸係合する方向（回動軸部６に沿った方向）にカム部９を係合付勢する構成としている。
【００３４】
従って、第一部材２（本体部２）に対して第二部材４（重合部４）を回動すると、本体部２に設けた第一取付部５の回動軸部６に対して重合部４に設けた第二取付部７の軸受部８（カム部９）が回動する。即ち、第二取付部７の軸受部８（カム部９）が、回動軸部６に対して回動し、回動軸部６に回り止め状態に設けたカム係合部１０（第一取付部５）に対してカム部９が回動することとなる。
【００３５】
従って、本体部２に対して重合部４を相対回動して重合状態とすると、回動軸部６を軸として係合付勢機構１１のバネにより押圧付勢されつつカム部９とカム係合部１０とは相対回動して、カム部９の凸部９Ａはカム係合部１０の凹部１０Ａに凹凸係合途中となる。
【００３６】
従って、係合付勢機構１１による押圧付勢とこの凹凸の吸い込み力によるカム係合付勢によって重合方向へ回動付勢（閉塞付勢）が生じ、この係合付勢機構１１に付勢された凹凸係合によって、重合状態が係合保持される。
【００３７】
また、本実施例では、開放方向に略１８０度弱回動した際、その開放回動位置が再び前記凹凸係合によってクリック保持されるように構成している。
【００３８】
従って、係合付勢機構１１による付勢によるカム部９とカム係合部１０との回動摩擦を適正となるように設定することで、スムーズな回動となると共に手を放した位置でその回動位置がこの摩擦によって保持されるフリーストップが実現でき、所定の開放回動位置で係合保持される間は自由な開放角度にこのフリーストップによって自在に調整できることとなる。
【００３９】
また、このフリーストップのための摩擦は回動当接面の状態や係合付勢機構１１の付勢力等によって調整できる。
【００４０】
尚、本実施例では、第一部材２側に回動軸部６、第二部材４側に軸受部８を構成し、第二部材４を開閉回動する重合部４としたが、勿論その逆でも良く、またカム部９とカム係合部１０との関係も同様で、その形成手段も本実施例に限らず様々な構成に設計可能である。
【００４１】
次に、反対側に設けるカメラ回動構造について説明する。
【００４２】
本実施例では、前述のように前記反対側の第一取付部５には前記回動軸部６を設けずに、前記カメラ回動軸部２０を軸支する前記カメラ軸受部２１を設け、この反対側の第一取付部５と対向する前記反対側の第二取付部７に設けた前記カメラ回動軸部２０を前記カメラ軸受部２１に回動自在に係合して、前記一方側の第一取付部５に設けた前記回動軸部６と連動せず別離状態にして略同一軸線上に前記カメラ回動軸部２０を設け、本実施例ではこのカメラ回動軸部２０の内端部に前記カメラ部２３を設け、前記左右の第一取付部５間に配設した前記カメラ部２３を前記カメラ回動軸部２０を軸に自転回動自在に設けている。
【００４３】
また、本実施例では前述のように、前記反対側の筒状の第二取付部７に前記カメラ回動軸部２０を設け、このカメラ回動軸部２０と共に回動する凸部２４Ａを有するカメラ回動用カム部２４を設け、前記カメラ軸受部２１と共に回動する凹部２５Ａを有するカメラ回動用カム係合部２５を前記反対側の第一取付部５に設け、この相対回動することで凹凸係合するカメラ回動用カム部２４を係合離反方向にスライド移動自在に設けると共に、このカメラ回動用カム部２４が係脱するに際して離反方向に移動した際係合方向に付勢するカメラ回動用係合付勢機構２６を設けて、前記カメラ部２３を自転回動した所定回動位置でこのカメラ回動用カム係合部２５とカメラ回動用カム部２４とが凹凸係合し、前記カメラ回動用係合付勢機構２６によりこの係合が保持されるあるいは係合付勢されるように構成し、このカメラ回動用カム部２４を前記カメラ回動用係合付勢機構２６に抗して離反方向に移動させつつ回動させることで前記カメラ回動用カム係合部２５に対してカメラ回動用カム部２４を係脱させ、カメラ部２３を自転回動するように構成している。
【００４４】
即ち、前記カメラ回動軸部２０を軸として前記左右の第一取付部５間で回動自在に配設した前記カメラ部２３が所定回動位置で凹凸係合して遂次クリック保持されるように構成している。また、このカメラ部２３の一側をカメラ回動軸部２０の内端部に取付固定すると共に反対側を前記回動軸部６の内端部に軸支している。
【００４５】
更に説明すると、本実施例では、前記第一取付部５の取付孔に凹部２５Ａを設けたカム係合凹部２５を回り止め状態に係合し、このカム係合凹部２５の挿通孔を前記カメラ軸受部２１として第一取付部５に設けている。
【００４６】
また、筒状の第二取付部７内にカメラ回動用係合付勢機構２６としてバネを内装し、このバネに抗してカメラ回動軸部２０に沿って移動自在にしてカメラ回動軸部２０に回り止め状態にカメラ回動用カム部２４を設けている。
【００４７】
即ち、本実施例では、第二取付部７に設けたカメラ回動用カム部２４を介してカメラ回動軸部２０を設け、このカメラ回動軸部２０を第一取付部５に設けたカメラ軸受部２１（カメラ回動用カム係合部２５）に軸支する構成とし、このカメラ回動軸部２０の内端部にＣＣＤカメラが組み込まれ指で回動操作する小筒状のカメラ部２３を取付固定している。
【００４８】
従って、第一部材２と第二部材４との枢着部の片側（本ヒンジ装置の片側）に配設した回動軸部６と軸受部８とにより開閉回動が行なわれ、反対側に設けたカメラ回動軸部２０とカメラ軸受部２１とによりカメラ部２３が中間位置で少なくとも１８０度表裏反転回動することとなる。
【００４９】
即ち、枢着部の片側には開閉回動用のヒンジ部が構成され、反対側にはカメラ回動用の回動構造が構成され、この間にカメラ部２３が少なくとも１８０度反転回動自在に組み込まれ、第一部材２に対する第二部材４の開閉回動に支障なく、この枢着部にカメラ部２３が回動自在に設けられ、この開閉回動を行なう本ヒンジ装置にカメラ回動軸部２０とカメラ軸受部２１が設けられ、これを用いて枢着部にカメラ部２３を回動自在に容易に設けることができることとなる。
【００５０】
また、本実施例では、前記開閉ヒンジ部においてのクリック係合（回動位置保持機構）は、前述のように０度で凹凸係合途中となり、１８０度弱開放した回動位置で再び凹凸係合するように構成するため、カム部９，カム係合部１０の凸部９Ａと凹部１０Ａの形成位置は、夫々二ヵ所ずつ１８０度対称位置に形成している。尚、凹凸係合する回動位相と合致するようにストッパー機構１３を設けている（本実施例では、筒状の第二取付部７の端部を切欠して第一取付部５を形成する連結金具５Ａの腕部が突き当たる段部を形成し、ストッパー機構１３を構成している。）。
【００５１】
これに対して、カメラ回動構造においては、カメラ部２３に露出形成したレンズ位置（カメラ向き）が背面側を向く位置と正面側を向く位置と本体部２内へ向きレンズ位置が隠れるいわば収納位置との合計三ヵ所において凹凸係合（クリック係合）するように構成している。即ち、本実施例では、カメラ部２３が約３００度近く回動し、その回動端とその途中との合計三ヵ所でクリック係合するように構成している。
【００５２】
一方、凹凸係合においては、一ヵ所の凹部と一ヵ所の凸部での係合では、係合力が弱まったり、片持係合するおそれがあるため、二ヵ所の凹部と二ヵ所の凸部で遂次凹凸係合するようにする必要がある。しかし、１８０度以上の総回動範囲における合計三ヵ所の回動位置で、二ヵ所の凸部が夫々遂次凹凸係合する場合は、単に同心位置の１８０度対象位置に凸部を二ヶ所設けたのでは、三ヵ所以外の余計な回動位置でもクリック係合することになってしまう。これを避けるべく本実施例のカメラ回動用カム部２４には、回動中心を境に二ヵ所の凸部２４Ａを設けるが、これを同心円上の位置とせず、半径方向に中心から距離がズレた位置に形成し、カメラ回動用カム係合部２５には、この夫々の凸部２４Ａに対応し前記三ヵ所の回動位置で夫々の凸部２４Ａが夫々遂次凹凸係合する位置に凹部２５Ａを形成している。
【００５３】
また、本実施例では、回動軸部６の内端部をカメラ部２３に軸支して、カメラ回動軸部２０を軸にして回動するカメラ部２３の回動がスムーズにして安定性良く行なうことができるようにしているが、この回動軸部６による軸支構造を利用してカメラ部２３の回動ストッパー機構２７を設けている。
【００５４】
即ち、回動軸部６の端部にピン２７Ａを突設し、この突設ピン２７Ａが突き当たる突き当たり部２７Ｂをカメラ部２３の端面に設け、カメラ部２３の過回動を阻止する構成としている。
【００５５】
尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。
【００５６】
【発明の効果】

For example, in a notebook computer or word processor or an openable / closable mobile phone, an open / close lid part (overlapping part) provided with a display part can be freely opened and closed via a hinge device with respect to a main body part provided with an operation part. The hinge device is provided with a superposition holding function for maintaining the closed state so that the overlapped portion is not opened without permission in the closed overlapped state where the overlapped portion is inclined to the main body. .
[0003]
That is, for example, a main body part or a cam part that rotates with the rotation of the superposition part, and a cam that rotates with the rotation of the superposition part or the main part, which are provided so as to be rotatable relative to each other about the rotation shaft part of the hinge device. When the engaging portion is in the closed overlapping state, the overlapping state is engaged and held by the convex portion provided on the cam portion and the concave portion provided on the cam engaging portion. Further, it is configured such that the concave and convex portions are engaged again at the time of opening rotation and the predetermined rotation position is engaged and held.
[0004]
On the other hand, electronic devices such as personal computers and mobile phones are equipped with a camera unit that can capture images stored like a digital camera, store the data, display it on the display unit, and transmit data.

This camera unit is provided with, for example, a camera unit incorporating a CCD camera, and this is wired, but until now it has only been attached to the main unit or superposition unit, so the orientation of the camera unit can be freely set. It cannot be changed.
[0005]
That is, as in the conventional camera, the CCD camera is placed on the back of the overlapping portion, for example, because it is based on the conventional concept of taking a picture by operating the shutter switch (image recording switch) with the CCD camera facing the subject. If provided, it is convenient to press the shutter switch while confirming the captured image displayed on the display unit in front of the overlapping section when shooting the opposite subject. You can flip the camera and turn the camera part toward you, so you can't shoot while looking at the display part.
[0006]
Therefore, in the present invention, in order to break down such a current situation, if the direction of the camera unit can be freely reversed and rotated to the far side or the near side, it is extremely easy to use, the use application is widened, and the commercial value. Focused on improving dramatically.
[0007]
In the present invention, when tackling such a technical problem, if the camera part is further arranged on the opening / closing pivot pivot part, the direction of the camera part is directed to the far side (rear side) as well as to the near side (front side). For example, it is possible to realize this easily by adopting a configuration that can be incorporated into a hinge device for opening and closing, while focusing on the fact that shooting as described above is always possible while being projected on the display unit. It was found that it was easy to manufacture and it was possible to realize an innovative electronic device with excellent mass productivity.
[0008]
That is, the present invention realizes an open / close hinge device with a camera rotation shaft portion that can be incorporated into the pivotally mounted portion of the camera portion so that the first member and the second member are overlapped as usual. In addition to being able to open / close and rotate while demonstrating the holding function, it is possible to easily incorporate the camera unit in a freely rotating manner without any hindrance to the opening / closing rotation, and the camera orientation can be changed freely on the back side or the front side. Moreover, the present invention provides an epoch-making hinge device and an electronic device using the hinge device, which can be easily pivotably disposed at an opening / closing pivot joint using the conventional opening / closing hinge device. The purpose is that.

[0016]
For example, when the second member 4 is rotated relative to the first member 2 to be in an overlapped state, the cam portion 9 and the cam engagement are pressed and urged by the engagement urging mechanism 11 about the rotation shaft portion 6. For example, the convex portion 9A of the cam portion 9 and the concave portion 10A of the cam engagement portion 10 are engaged with each other in the concave-convex engagement or in the middle of engagement.
[0017]
Accordingly, the pressing force by the engagement biasing mechanism 11 and the cam engagement biasing by the concave and convex suction force cause a rotation biasing (blocking biasing) in the superposition direction, and the engagement biasing mechanism 11 is biased. The overlapped state is engaged and held by the uneven engagement.
[0018]
As described above, although not limited to the overlapped closure, the cam portion 9 and the cam engagement portion 10 are engaged with each other so that the predetermined rotation position is held or biased by this cam engagement. The
