Description

【０００１】
【発明の属する技術分野】
本発明は、車体のほぼ前後方向に移動して、車体に形成された開口を閉鎖し、又は開放する開閉扉を備えた車両の開閉扉装置に関する。
【０００２】
【従来の技術】
車体の前後方向に移動する所謂引き戸式の開閉扉を備えた開閉扉装置は従来より周知である。従来のこの種の開閉扉は、車体の側部に形成された開口、例えば乗降口を閉鎖する全閉位置と、その開口を開放する全開位置との間を車体の前後方向に直線運動するように車体に支持されている。かかる開閉扉が全開位置を占めたとき、その開閉扉は、これに隣接する車体外壁部よりも車体幅方向車内側に位置し、その車体外壁部によって外部から隠蔽される。
【０００３】
上述のように、従来の開閉扉は、車体外壁部によって隠蔽される全開位置と、開口を閉鎖する全閉位置との間を直線運動するように構成されているため、開閉扉が全閉位置にあるとき、その開閉扉は、車体外壁面よりも車室内側に大きく入り込んだ位置を占める。このように全閉位置を占めた開閉扉の車外側面が、その開閉扉のまわりの車体外側面よりも車内側に大きく入り込んでいると、車両全体の外観が低下するだけでなく、車両走行時の空力特性が低下し、しかも開閉扉の車外側面近傍に生じる空気の乱流によって、開閉扉の車外側面に空気中の汚れが付着しやすくなる欠点を免れない。
【０００４】
【発明が解決しようとする課題】
本発明の目的は、上記従来の欠点を除去することのできる車両の開閉扉装置を提供することにある。
【０００５】
【課題を解決するための手段】
本発明は、上記目的を達成するため、車体に形成された開口を閉鎖又は開放する開閉扉と、該開閉扉上部の車体前後方向の一端側に設けられた第１のガイドローラと、開閉扉上部の車体前後方向の他端側に設けられた第２のガイドローラと、車体のほぼ前後方向に延びていて、該車体に固定され、かつ前記第１のガイドローラが転動自在に嵌合した第１のガイドレールと、車体のほぼ前後方向に延びていて、該車体に固定され、かつ前記第２のガイドローラが転動自在に嵌合した第２のガイドレールと、車体のほぼ前後方向に移動して、前記開閉扉が前記開口を閉鎖する全閉位置と該開口を開放する全開位置との間を移動するように、該開閉扉を駆動する駆動装置とを具備し、前記開閉扉が全開位置を占めたとき、該開閉扉は、これに隣接する車体外壁部よりも車体幅方向車内側に位置する車両の開閉扉装置であって、前記第１のガイドローラと第２のガイドローラをほぼ水平方向に首振り自在に前記開閉扉に連結すると共に、全閉位置へ向けて移動する開閉扉がその全閉位置に近い位置から全閉位置へ移動するとき前記第１のガイドローラが転動する第１のガイドレール部分を、車体幅方向車外側へ向けて湾曲形成し、前記開閉扉が全閉位置を占めたとき、前記駆動装置からの力が開閉扉の前記一端側を車体幅方向車外側に加圧する力として当該開閉扉に作用するように、駆動装置からの力の向きを変える変換手段を具備し、該変換手段が、前記駆動装置と開閉扉とにそれぞれ揺動可能に枢着された中間部材と、車体に固定されていて、前記第１のガイドローラが第１のガイドレールの湾曲した部分を通るとき、前記中間部材に係合して、該中間部材の回転中心を構成する係合ピンとを有し、前記開閉扉が全閉位置へ向けて移動し、第１のガイドローラが第１のガイドレールの湾曲した部分を通るとき、前記係合ピンに係合した前記中間部材は、前記駆動装置からの力により、前記係合ピンのまわりに、車体幅方向車外側に向けて回動し、開閉扉の前記一端側を車体幅方向車外側に加圧することを特徴とする車両の開閉扉装置を提案する（請求項１）。
【０００６】
同じく、本発明は、上記目的を達成するため、車体に形成された開口を閉鎖又は開放する開閉扉と、該開閉扉上部の車体前後方向の一端側に設けられた第１のガイドローラと、開閉扉上部の車体前後方向の他端側に設けられた第２のガイドローラと、車体のほぼ前後方向に延びていて、該車体に固定され、かつ前記第１のガイドローラが転動自在に嵌合した第１のガイドレールと、車体のほぼ前後方向に延びていて、該車体に固定され、かつ前記第２のガイドローラが転動自在に嵌合した第２のガイドレールと、車体のほぼ前後方向に移動して、前記開閉扉が前記開口を閉鎖する全閉位置と該開口を開放する全開位置との間を移動するように、該開閉扉を駆動する駆動装置とを具備し、前記開閉扉が全開位置を占めたとき、該開閉扉は、これに隣接する車体外壁部よりも車体幅方向車内側に位置する車両の開閉扉装置であって、前記第１のガイドローラと第２のガイドローラをほぼ水平方向に首振り自在に前記開閉扉に連結すると共に、全閉位置へ向けて移動する開閉扉がその全閉位置に近い位置から全閉位置へ移動するとき前記第１のガイドローラが転動する第１のガイドレール部分を、車体幅方向車外側へ向けて湾曲形成し、前記開閉扉が全閉位置を占めたとき、前記駆動装置からの力が開閉扉の前記一端側を車体幅方向車外側に加圧する力として当該開閉扉に作用するように、駆動装置からの力の向きを変える変換手段を具備し、該変換手段が、前記駆動装置と開閉扉とにそれぞれ揺動可能に枢着され、かつ開閉扉が全閉位置を占めたとき、開閉扉の前記一端側が車体幅方向車外側に加圧される向きの力として前記駆動装置からの力を該開閉扉に伝達する中間部材を有していることを特徴とする車両の開閉扉装置を提案する（請求項２）。
【０００８】
【発明の実施の形態】
以下、本発明の実施形態例を図面に従って詳細に説明する。
【０００９】
図１は車両の一例であるバスの側面図であり、その車体１の側部に乗客の乗降口となる開口２が形成されている。この開口２は、図１に示すように開閉扉３によって閉鎖される。この開閉扉３は、車体１のほぼ前後方向Ｘに移動可能であり、開閉扉３が図１に鎖線で示した全開位置に移動することによって開口２が開放され、この開口２を通して乗客がバスの室内に乗り込み、又は室内から降りることができる。開閉扉３は、扉本体４と、その上部に固設された窓ガラス５を有している。また本明細書における車体の前後方向Ｘとは、車両前進方向を前方Ｘ１、その反対方向を後方Ｘ２としたときの前後方向を意味する。
【００１０】
図２乃至図４は上述した開閉扉３を含む開閉扉装置６の概略水平断面図であり、図２は、開閉扉３が全閉位置を占めたときの様子を示し、図３は開閉扉３が全閉位置と全開位置の間の中間位置にあるときの状態を示しており、さらに図４は開閉扉３が全開位置に移動したときの様子を示している。また、図５は図３のＶ−Ｖ線拡大断面図であり、図６は図３のVI−VI線拡大断面図である。これらの図に符号Ｏで示す側が車外側であり、符号Ｉで示す側が車内側である。また符号Ｗは、車体の幅方向を示している。
【００１１】
図１乃至図６に示すように、扉本体４の上部の車体前後方向Ｘの一端側と他端側には、第１及び第２のブラケット７，８がそれぞれ固定され、その各ブラケット７，８には、ローラ支持部材９，１０が水平面内を回転可能に支持され、その各ローラ支持部材９，１０の上端部に、第１及び第２のガイドローラ１１，１２が、その水平軸線のまわりに回転自在に支持されている。これらのガイドローラ１１，１２は、その各ローラ支持部材９，１０と共に、その垂直軸線のまわりに回転自在に、すなわち水平面内を回転自在に各ブラケット７，８にそれぞれ支持されている。第１及び第２のガイドローラ１１，１２は、ほぼ水平方向に首振り自在に開閉扉３に連結されているのである。
【００１２】
上述の第１及び第２のガイドローラ９，１０は、車体１に固定された第１及び第２のガイドレール１３，１４にそれぞれ転動自在に嵌合している。第１及び第２のガイドレール１３，１４は、車体１のほぼ前後方向Ｘに延びていて、図示した例では、第１のガイドレール１３が第２のガイドレール１４よりも車体１の前方Ｘ１側に位置している。各ガイドレール１３，１４は、図７に拡大して示すように、上壁１５と、その幅方向端縁から下方に垂下する一対の側壁１６，１６と、その各側壁１６，１６の下端から互いに接近する向きに突出するフランジ１７，１７とから成り、その両フランジ１７，１７の間をローラ支持部材９，１０がそれぞれ上方に延び、各フランジ１７，１７の上面にガイドローラ１１，１２がそれぞれ転動自在に載置されている。このように、開閉扉３は、ローラ支持部材９，１０とガイドローラ１１，１２を介して、各ガイドレール１３，１４に懸架されている。
【００１３】
上述の如く、本例の車両の開閉扉装置は、車体１に形成された開口２を閉鎖又は開放する開閉扉３と、この開閉扉上部の車体前後方向Ｘの一端側に設けられた第１のガイドローラ１１と、開閉扉上部の車体前後方向Ｘの他端側に設けられた第２のガイドローラ１２と、車体１のほぼ前後方向Ｘに延びていて、その車体１に固定され、かつ第１のガイドローラ１１が転動自在に嵌合した第１のガイドレール１３と、車体１のほぼ前後方向に延びていて、その車体１に固定され、かつ第２のガイドローラ１２が転動自在に嵌合した第２のガイドレール１４とを有している。
【００１４】
また、第１のガイドレール１３に隣接してガイドロッド１８が位置し、このガイドロッド１８は、その長手方向各端部が車体１に固定され、第１のガイドレール１３に対して平行に、すなわち車体１のほぼ前後方向Ｘに延びている。かかるガイドロッド１８には、開閉扉３を駆動する駆動装置１９が摺動自在に嵌合している。図に一例として示した駆動装置１９は、それ自体周知なエアシリンダにより構成され、かかる駆動装置１９にエアを給排することによって、当該駆動装置１９は、ガイドロッド１８に沿って、図２に示した位置と図４に示した位置との間を車体１のほぼ前後方向Ｘに移動する。
【００１５】
駆動装置１９は、後述する中間部材２０を介して開閉扉３の第１のブラケット７に連結され（図８及び図９も参照）、駆動装置１９が上述のように移動することにより、開閉扉３が図２に示した全閉位置と図４に示した全開位置の間を移動する。すなわち、今、開閉扉３が図４に示した全開位置にあったとし、この状態で駆動装置１９が作動を開始してガイドロッド１８に沿って車体１の後方Ｘ２に向けて移動すると、開閉扉３は、その第１のブラケット７が、中間部材２０を介して駆動装置１９により押され、車体１の後方Ｘ２に向けて移動する。このとき、第１及び第２のガイドローラ１１，１２が、第１及び第２のガイドレール１３，１４をそれぞれ転動しながら、その各ガイドレール１３，１４によって案内され、開閉扉３は、図３に示した中間位置を通って、図２に示した全閉位置に至る。このようにして、車体１に形成された開口２が閉鎖される。駆動装置１９が車体１の前方Ｘ１へ向けて移動することにより、開閉扉３は図４に示した全開位置に移動することができる。
【００１６】
上述のように、本例の車両の開閉扉装置６は、車体１のほぼ前後方向に移動して、開閉扉３が開口２を閉鎖する全閉位置とその開口２を開放する全開位置との間を移動するように、該開閉扉３を駆動する駆動装置１９を具備している。
【００１７】
開閉扉３が図４に示した全開位置を占めたとき、その開閉扉３は、これに隣接する車体外壁部１Ａよりも、車体幅方向Ｗにおける車内側Ｉに位置する。
【００１８】
ここで、図２乃至図４に示すように、第１のガイドレール１３の一方の端部領域、図の例では車体後方側の端部領域が車体幅方向Ｗにおける車外側Ｏに向けて湾曲形成されている（図８及び図９も参照）。すなわち、全閉位置へ向けて移動する開閉扉３が、その全閉位置に近い位置（ほぼ図３に示す位置）から全閉位置へ移動するとき第１のガイドローラ１１が転動する第１のガイドレール１３の部分１３Ａが、車体幅方向車外側Ｏへ向けて湾曲形成されている。
【００１９】
上記構成により、図２から判るように、開閉扉３が全閉位置に至ったとき、その開閉扉３の一端側、すなわち第１のガイドローラ１１が付設された開閉扉３の端部側が、車体幅方向Ｗにおける車外側Ｏに大きく移動した位置を占める。このため、全閉位置を占めた開閉扉３は、その近傍の車体外側面、すなわち車体外壁部１Ａの車外側面に対してほぼ連続した面一状態となる。これにより、車両全体の外観が高められ、しかも車両走行時の空力特性が向上する。さらに、車両の走行時に、全閉位置を占めた開閉扉３の車外側近傍に空気の乱流が生じることが抑えられ、開閉扉３の車外側面に空気中の汚れが付着する不具合を抑制することができる。
【００２０】
第１のガイドレール１３の湾曲した部分１３Ａを第１のガイドローラ１１が転動するとき、図２及び図３から判るように、開閉扉３の姿勢が変化するが、前述のように第１のガイドローラ１１と第２のガイドローラ１２は、ほぼ水平方向に首振り自在に開閉扉３に連結されているので、第１のガイドローラ１１が第１のガイドレール１３の湾曲した部分１３Ａを通るとき、その湾曲形態に合せて第１のガイドローラ１１が水平方向に回転し、同じく第２のガイドローラ１２が回転するので、開閉扉３は支障なくその姿勢を変化させながら全閉位置へ移動し、またその全閉位置から全開位置へ向けて移動することができる。
【００２１】
図８は図３の部分拡大図であり、図９は図２の部分拡大図である。図５及び図８に示すように、駆動装置１９には、ピン２１が突設され、このピン２１は、前述の中間部材２０に形成された長孔２２に、相対回転自在かつ相対摺動自在に嵌合している。また開閉扉３の第１のブラケット７に突設されたピン２３は、中間部材２０に形成された孔２４に相対回転自在に嵌合している。このように、中間部材２０は、ピン２１，２３と、これが嵌合した孔２２，２４を介して、駆動装置１９と開閉扉３とにそれぞれ揺動可能に枢着されている。
【００２２】
図４に示した全開位置にあった開閉扉３が、車体の後方Ｘ２に向けて移動を開始した駆動装置１９によって加圧されたとき、その力は、中間部材２０を介してそのまま開閉扉３に伝えられ、開閉扉３は車体１のほぼ後方Ｘ２に向けて移動する。そして、その開閉扉３が図３に示した位置に至ると、図８に拡大して示すように、中間部材２０に形成された円弧状の係合部２５が、車体１に固定された丸棒状の係合ピン２６に係合する。
【００２３】
駆動装置１９が車体１の後方Ｘ２に向けてさらに移動すると、第１のガイドローラ１１は第１のガイドレール１３の湾曲した部分１３Ａを通るが、このとき、中間部材２０は、その係合部２５が係合ピン２６に係合しているため、駆動装置１９からの力を受けながら、係合ピン２６のまわりに、図８における時計方向、すなわち車体幅方向Ｗにおける車外側Ｏに向けて回動する。
【００２４】
次いで開閉扉３が図２及び図９に示す全閉位置に至ると、中間部材２０は図９に示す姿勢を占める。このとき開閉扉３は全閉位置を占め、その縁部が車体１の開口２のまわりに設けられた弾性材より成るウェザストリップ２７（図２乃至図６には図示せず）に当接して停止する。このため、駆動装置１９も図９に示した位置に停止するが、このとき駆動装置１９の作動は停止しない。これにより、中間部材２０には係合ピン２６のまわりの回転モーメントが加えられ、当該中間部材２０は、開閉扉３の一端側、すなわち第１のガイドローラ１１が設けられた側の開閉扉部分を車体幅方向車外側Ｏへ押圧する。中間部材２０は、駆動装置１９からの力が、開閉扉３の一端側を車体幅方向車外側に加圧する力として開閉扉３に作用するように、駆動装置１９からの力の向きを変換するのである。このため、全閉位置に至った開閉扉３は、その全閉位置に確実に保持され、車外側から開閉扉３を押したとしても、開閉扉３は開放されずにその閉位置に留められる。
【００２５】
上述のように、本例の車両の開閉扉装置６は、開閉扉３が全閉位置を占めたとき、駆動装置１９からの力が開閉扉３の一端側を車体幅方向車外側Ｏに加圧する力として当該開閉扉３に作用するように、駆動装置１９からの力の向きを変える変換手段を具備している。そして図示した例では、その変換手段が、駆動装置１９と開閉扉３とにそれぞれ揺動可能に枢着された中間部材２０と、車体１に固定されていて、第１のガイドローラ１１が第１のガイドレール１３の湾曲した部分１３Ａを通るとき、中間部材２０に係合して、その中間部材２０の回転中心を構成する係合ピン２６とを有していて、開閉扉３が全閉位置へ向けて移動し、第１のガイドローラ１１が第１のガイドレール１３の湾曲した部分１３Ａを通るとき、係合ピン２６に係合した中間部材２０は、駆動装置１９からの力により、係合ピン２６のまわりに、車体幅方向車外側Ｏに向けて回動し、開閉扉３の一端側を車体幅方向車外側Ｏに加圧するように構成されている。
【００２６】
上述の変換手段を設けることにより、駆動装置１９の作動によって、開閉扉３をその全閉位置に確実に保持することができ、また上述のように、中間部材２０と係合ピン２６を有する変換手段を採用すると、係合ピン２６のまわりに回動した中間部材２０が、駆動装置１９からの力を、開閉扉３を車体幅方向車外側へ向く力として、開閉扉３に効率よく伝達し、開閉扉３をより確実にその全閉位置に保持することができる。
【００２７】
また、本例の開閉扉装置６には、図５及び図６に示すように、開閉扉３が前述の如く全開位置と全閉位置の間を移動するとき、その開閉扉３の下部をガイドする第１及び第２の案内レール２８，２９が設けられている。図１０は、図５及び図６に示した第１及び第２の案内レール２８，２９を上方から見た平面図であり、図１１は図１０の部分拡大図である。これらの図には、全閉位置にある開閉扉３を破線で、中間位置にある開閉扉３を一点鎖線で、全開位置にある開閉扉３を二点鎖線でそれぞれ示してある。図５、図６及び図１０から判るように、第１及び第２の案内レール２８，２９は車体１の床面に固定され、それぞれ第１のガイドローラ１１と第２のガイドローラ１２に対向して位置している。第１の案内部材２８は、上部が開放したほぼＵ字形横断面の細長部材より成り、第２の案内部材２９は、薄い板材の細長部材から成る。また、開閉扉３の下部の車体前後方向一端側には、ロアガイドローラ３０が回転自在に支持され、開閉扉３の下部の車体前後方向他端側には、下側に開放されたガイド溝３１が形成されたガイド部片３２が固定されている。
【００２８】
開閉扉３が図１０及び図１１に二点鎖線で示した全開位置にあるとき、ロアガイドローラ３０は第１の案内レール２８に嵌合し、ガイド部片３２のガイド溝３１は第２の案内レール２９に嵌合している。開閉扉３が車体１の後方Ｘ２に向けて移動し、図１０及び図１１に一点鎖線で示した位置に至り、次いで、前述のように、第１のガイドローラ１１が第１のガイドレール１３の湾曲した部分１３Ａを転動しながら移動し始めたとき、ロアガイドローラ３０は第１の案内レール２８の後端部２８Ａから外れる。ガイド部片３２のガイド溝３１は、開閉扉３が全閉位置に至ったときも、第２の案内レール２９に嵌合したままである。
【００２９】
上述のように、開閉扉３がその全開位置と全閉位置の間を移動するとき、その下部の側が第１及び第２の案内レール２８，２９によってガイドされるので、開閉扉３が車体幅方向Ｗに振らつき、これが不安定となる不具合を阻止できる。
【００３０】
図１２及び図１３は、図８及び図９に示した変換手段とは異なる形態の変換手段を有する開閉扉装置６の第２の実施形態例を示し、これらの図は図８及び図９に相当する図である。また図１４はこの第２の形態の実施形態例の、図５に相当する断面図である。
【００３１】
図１２乃至図１４に示すように、第２の実施形態例の変換手段は、棒状の中間部材１２０を有し、その各長手方向端部が、ボールジョイント３３，３４を介して、駆動装置１９と開閉扉３の第１のブラケット７に揺動可能に連結されている。第２の形態の変換手段は、図８及び図９に示した係合ピン２６は有していない。図１２乃至図１４に示した開閉扉装置６の他の構成は、図１乃至図１１に示した開閉扉装置と変りはない。
【００３２】
第２の実施形態例においても、駆動装置１９が車体１の後方Ｘ２に向けて移動し、その力が中間部材１２０を介して開閉扉３の第１のブラケット７に伝えられ、開閉扉３がその全開位置から全閉位置へ向けて移動する。開閉扉３が図１３に示した全閉位置に至り、その縁部が車体１のウェザストリップ２７に当接したとき、駆動装置１９は依然として作動を続けながら移動を停止するが、このときの駆動装置１９からの力は、中間部材１２０を介して開閉扉３の一端側の第１のブラケット７に伝えられる。このとき、開閉扉３は、中間部材１２０から、矢印Ｆで示すように、開閉扉３の一端側が車体幅方向Ｗにおける車外側Ｏに加圧される向きの力を受ける。このため、前述の第１の実施形態例の場合と同様に、開閉扉３はその全閉位置に強固に保持され、この状態で車外側から開閉扉３を車内側へ向けて押圧する力が作用しても、開閉扉３はその全閉位置に保持される。
【００３３】
上述のように、第２の実施形態例の変換手段も、開閉扉３が全閉位置を占めたとき、駆動装置１９からの力が開閉扉３の一端側を車体幅方向車外側に加圧する力として当該開閉扉３に作用するように、駆動装置１９からの力の向きを変える用をなし、しかも、この変換手段は、駆動装置１９と開閉扉３とにそれぞれ揺動可能に枢着され、かつ開閉扉が全閉位置を占めたとき、開閉扉３の一端側が車体幅方向車外側Ｏに加圧される向きの力として駆動装置１９からの力を開閉扉３に伝達する中間部材１２０を有している。この例の変換手段によれば、係合ピン２６が不要であるため、その構成を簡素化でき、かつそのコストの低減を達成できる。
【００３４】
本発明は、バス以外の各種自動車、或いは鉄道車両などの車両にも広く適用できるものである。
【００３５】
【発明の効果】
請求項１及び２に係る発明によれば、開閉扉が全閉位置を占めたとき、その車外側面を当該開閉扉の近傍の車体外面とほぼ面一状態にすることが可能であり、これにより車両全体の外観を向上させ、車両走行時の空力特性を高めることができる。しかも、開閉扉が全閉位置を占めたとき、駆動装置からの力が開閉扉の一端側を車体幅方向車外側に加圧する力として当該開閉扉に作用するように、駆動装置からの力の向きを変える変換手段を有しているので、駆動装置の作動力によって、開閉扉をその全閉位置に確実に保持することができる。
【００３６】
また請求項１に係る発明によれば、変換手段によって、駆動装置の作動力を、車体幅方向車外側へ効率よく変換でき、開閉扉をその全閉位置により確実に保持することができる。
【００３７】
さらに、請求項２に係る発明によれば、変換手段の構成を簡素化でき、そのコストの低減を達成できる。

BACKGROUND OF THE INVENTION
The present invention relates to an opening / closing door device for a vehicle that includes an opening / closing door that moves substantially in the front-rear direction of the vehicle body to close or open an opening formed in the vehicle body.
[0002]
[Prior art]
An open / close door device provided with a so-called sliding door type open / close door that moves in the front-rear direction of the vehicle body is conventionally known. This type of conventional open / close door linearly moves in the front-rear direction of the vehicle body between an opening formed on a side portion of the vehicle body, for example, a fully closed position for closing the entrance / exit and a fully open position for opening the opening. Is supported by the car body. When such an open / close door occupies the fully open position, the open / close door is positioned on the inner side in the vehicle width direction of the vehicle body outer wall adjacent to the door, and is hidden from the outside by the vehicle body outer wall.
[0003]
As described above, the conventional open / close door is configured to linearly move between the fully open position concealed by the outer wall of the vehicle body and the fully closed position that closes the opening. When the door is open, the open / close door occupies a position that is deeper into the vehicle interior than the outer wall surface of the vehicle body. If the outside surface of the open / close door that occupies the fully closed position enters the inside of the vehicle more than the outside surface of the vehicle body around the open / close door, not only the appearance of the entire vehicle will deteriorate, but also when the vehicle is running The aerodynamic characteristics of the open / close door are deteriorated, and air turbulence generated in the vicinity of the outside surface of the open / close door inevitably suffers from the disadvantage that dirt in the air easily adheres to the outside surface of the open / close door.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to provide a vehicle opening / closing door device that can eliminate the above-mentioned conventional drawbacks.
[0005]
[Means for Solving the Problems]
