Description

【０００１】
【発明の属する技術分野】
この発明は、自動車、航空機、船舶などの乗り物のフロントウインドパネルなど窓に付着した雨水やゴミを払拭することが可能なると共に寒冷地や冬季に使用されるウインター用ワイパーに関する。
【０００２】
【従来の技術】
従来のウインター用ワイパーは、例えば特開平１０−１６７１９号公報に示すようなものがある。かかる構成によれば、ブレード部材（２）の劣化に伴い、ウインター用ブレード全体を交換する必要がなく、ブレード部材（２）のみの交換ですむために、払拭面（１）を払拭可能なるブレード部材（２）と、該ブレード部材（２）の保持部（２１）を出し入れ自在なると共に係合した状態で保持可能に形成され且つ該ブレード部材（２）に弾性を付与するバーティブラ（３）と、前記ブレード部材（２）を払拭駆動可能なる駆動部材（８）と、前記バーティブラ（３）及び前記駆動部材（８）間に介在支持されてなる保持レバー機構と、両端に開口部が形成される筒形状をなし且つ前記バーティブラ（３）、前記保持レバー機構、前記ブレード部材（２）の払拭部（２０）を除く部位を覆う防水性を有するカバー（７）と、前記ブレード部材（２）が前記保持レバー機構からの脱落を防止するように前記カバー（７）の少なくとも一端部に装着され且つ水滴が前記カバー（７）の開口部から侵入して凍結するのを防止した防水ストッパ（１０）とを備えてなる構造が開示されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、かかるウインター用ワイパーにあっては、カバー（７）に防水ストッパ（１０）の固定部材（９１）を確実に支持するために、カバー（７）と固定部材（９１）との隙間に接着剤を塗布しているので、接着剤が、該隙間からあふれ出るおそれがあり、外観を損なうことになる。また、両者（７，９１）の隙間を伝わってブレード部材（２）まで接着剤が達するおそれがあり、かかる場合、ブレード部材（２）が他の部品との間で接着されて、外せなくなるおそれがある。また、接着剤が固化するまで時間がかかり、製品化への総時間が多く必要とする。更に、接着剤が他の部品に付着するおそれがあり、かかる場合、商品性を損なうことになる。
【０００４】
また、防水ストッパ（１０）の構造が、固定部材（９１）に対して着脱部材（９２）が上下に進退するタイプであり且つ該防水ストッパ（１０）が露出しているため、固定部材（９１）と着脱部材（９２）との隙間の方向が、雪などの浸入しやすい方向となり、凍結するおそれがあり、改善が求められている。また、防水ストッパ（１０）の着脱部材（９２）を固定部材（９１）から離脱させる際に、指又は工具等で着脱部材（９２）の弾性係合爪（９２１）を内側に撓ませて押し込むことにより固定部材（９１）の挿入溝（９１５）から取り外すことができるが、意に反して両者（９１５，９２１）が離脱してしまうと、そのまま防水ストッパ（１０）が脱落し紛失してしまうおそれがある。
【０００５】
そこで、この発明は、防水ストッパの固定部材と着脱部材との固定手段として、接着剤を用いずに確実に支持可能なるようにすると共に該防水ストッパの固定部材と着脱部材との間に雪などが侵入しにくいようにし、更に防水ストッパの意に反した離脱をしても脱落しないようにしたウインター用ワイパーを提供することを目的としている。
【０００６】
【課題を解決するための手段】
前記目的を達成するために、請求項１に記載の発明は、払拭面を払拭可能なるブレード部材と、該ブレード部材の保持部を出し入れ自在なると共に係合した状態で保持可能に形成され且つ該ブレード部材に弾性を付与するバーティブラと、前記ブレード部材を払拭駆動可能なる駆動部材と、前記バーティブラ及び前記駆動部材間に介在支持されてなる保持レバー機構と、両端に開口部が形成される筒形状をなし且つ前記バーティブラ、前記保持レバー機構、前記ブレード部材の払拭部を除く部位を覆う防水性を有するカバーと、前記ブレード部材が前記保持レバー機構からの脱落を防止するように前記カバーの少なくとも一端部に装着され且つ水滴が前記カバーの開口部から侵入するのを防止した防水ストッパとを備えてなるウインター用ワイパーにおいて、前記防水ストッパは、固定部材と、着脱部材とより構成されてなり、前記固定部材は、前記バーティブラの端部に支持されることで前記カバーの開口部を水密に閉塞してなり且つ前記ブレード部材の保持部の着脱が可能なる出し入れ口が形成されてなり、前記着脱部材は、前記固定部材の支持手段により前記カバーの長手方向から固定部材に着脱自在なると共に該固定部材に支持された状態で前記ブレード部材の保持部の着脱を阻止したストッパ部が形成されてなり、前記固定部材の支持手段は、前記着脱部材の一側から他側に貫通して、該他側で着脱部材に支持してなる。
【０００７】
請求項１に記載の発明によれば、前記固定部材の支持手段により、前記カバーの長手方向から固定部材に着脱自在なると共に該固定部材に支持された状態で前記ブレード部材の保持部の着脱を阻止したストッパ部が形成されてなる着脱部材によりなるので、着脱部材を固定部材から離脱させれば、ブレード部材の交換が可能なる構成を維持している。また、接着剤を用いずに固定部材に着脱部材を確実に支持可能であるので、接着剤が、隙間からあふれ出たり、隙間を伝わってブレード部材を他の部品に固着して外せなくなったり、製品化への総時間が多く必要とするなどの従来の不具合が一掃される。更に、接着剤を用いずに固定部材の支持手段が着脱部材に支持させるだけで、確実に支持可能である。しかも、固定部材の支持手段に対して一側から他側に挿入するだけで、他側に支持されるので、取付作業が簡易である。
【００１０】
請求項２に記載の発明は、請求項１に記載のウインター用ワイパーであって、前記固定部材の支持手段は、前記固定部材から延在された舌状の弾性変形可能なる係合片よりなり、前記着脱部材には、該着脱部材の他側から離脱した前記係合片が、抜け方向で再度係合可能なる第２係合部が形成されてなる。
【００１１】
請求項２に記載の発明によれば、弾性変形可能なる係合片により、固定部材の支持手段が形成されているので、着脱部材に係合した状態から離脱させるには、力を係合片に加えて、一旦係合片を撓ませる必要があり、該力を解除すれば、係合片は、再び係合する方向に撓むことになる。この作用原理を利用して、第２係合部を着脱部材の係合部より一側の位置に形成したことにより、意に反して着脱部材の係合部から係合片が外れても、一側（抜け方向）に移動する途中に設けた第２係合部に、係合片は再び係合できる。つまり、着脱部材は意に反して固定部材から外れないことになる。
【００１２】
請求項３に記載の発明は、請求項１に記載のウインター用ワイパーであって、前記固定部材の支持手段は、締結具により前記着脱部材に螺結結合してなる。
【００１３】
請求項３に記載の発明によれば、接着剤を用いずに締結具により着脱部材を確実に支持可能であるので、支持作業が簡易である。
【００１４】
請求項４に記載の発明は、請求項１乃至請求項３の何れか１項に記載のウインター用ワイパーであって、前記着脱部材には、前記固定部材の支持手段を覆う被覆部材が支持されてなり、該被覆部材自体の張力により前記着脱部材に着脱可能なるようにした。
【００１５】
請求項４に記載の発明によれば、被覆部材で固定部材の支持手段を閉塞してなるので、支持手段が露出されていず、支持手段への操作を知らない者には、着脱部材をいたずらなどによって外すことを難しくしている。また、被覆部材で着脱部材を被覆してなることにより、該防水ストッパの固定部材と着脱部材との間に雪などが侵入しにくいことになる。
【００１６】
請求項５に記載の発明は、請求項１乃至請求項４の何れか１項に記載のウインター用ワイパーであって、前記着脱部材のストッパ部は、前記固定部材の出し入れ口と略同一形状に形成されて、該出し入れ口に係合可能なるように凸状に形成されてなる。
【００１７】
請求項５に記載の発明によれば、凸状をなす着脱部材のストッパ部が、固定部材の出し入れ口に係合可能であるので、該出し入れ口から出し入れ可能なるブレード部材をバーティブラ内に確実に保持可能となる。また、着脱部材と固定部材との間に雨水等が侵入しても、ストッパ部と出し入れ口とが密接状態であるので、それ以上侵入できにくく、シール性が向上する。
【００１８】
請求項６に記載の発明は、請求項４に記載のウインター用ワイパーであって、前記被覆部材は、弾力性を有する袋状より形成されてなる。
【００１９】
請求項６に記載の発明によれば、袋状の被覆部材を引っ張れば開口が拡大し、着脱部材に容易に被覆が可能である。
【００２０】
【発明の実施の形態】
以下、図１乃至図１１の図面を参照しながら、この発明の第１実施形態について具体的に説明する。
【００２１】
図１において、符号１は、ウインター用ワイパーであって、該ウインター用ワイパー１は、自動車のフロントウインドパネルなどの払拭面２を払拭可能なるブレード部材３と、該ブレード部材３の保持部３ａを出し入れ自在なると共に係合した状態で保持可能に形成され且つ該ブレード部材３に弾性を付与するバーティブラ４と、前記ブレード部材３を払拭駆動可能なる駆動部材５と、前記バーティブラ４及び前記駆動部材５間に介在支持されてなる保持レバー機構６と、両端に開口部７ａが形成される筒形状をなし且つ前記バーティブラ４、前記保持レバー機構６、前記ブレード部材３の払拭部３ｂを除く部位を覆うことでそれらに雪や氷等が付着するのを防ぐ防水性を有するカバー７と、前記ブレード部材３が前記保持レバー機構６からの脱落を防止するように前記カバー７の少なくとも一端部である開口部７ａに装着され且つ水滴が前記カバー７の開口部７ａから侵入するのを防止した防水ストッパ８とを備えてなる。
【００２２】
前記バーティブラ４は、図４に示すように、Ｃの字を横に倒したような断面形状をなし、その切欠４ａは、後述するブレード部材３の保持部３ａと払拭部３ｂとの間に形成されてなる頸部３ｃが通過可能なるように形成されている。
【００２３】
前記防水ストッパ８は、固定部材９と、着脱部材１０と、該着脱部材１０を覆うことを可能とした被覆部材１１とより構成されてなる。
【００２４】
前記固定部材９は、図５乃至図９に示すように、鍔部１２と、該鍔部１２より前記カバー７の内側に延在形成されてなる固定部１３と、前記鍔部１２より前記カバー７の外側に延在形成されてなる「支持手段」としての支持部１４とが、ナイロン、ジュラコンなどの合成樹脂材より一体に形成されてなる。
【００２５】
前記鍔部１２は、一面１２ａが平面状をなし、他面１２ｂには、後述する支持部１４のガイド部１４ｂ、１４ｂを保持する盛り上がり部１２ｃが形成されている。前記一面１２ａは、前記カバー７の開口部７ａの端末に密接に接すると共に該開口部７ａの端末に接着剤などにより水密に閉塞してなる。また、前記一面１２ａから他面１２ｂの盛り上がり部１２ｃにかけて、前記ブレード部材３の保持部３ａ及び該保持部３ａと払拭部３ｂとの間に形成されてなる頸部３ｃが通過可能なＴ字形の「出し入れ口」である切欠部１２ｄが形成されている。
【００２６】
前記固定部１３は、前記鍔部１２に対して、前記カバー７の開口部７ａの端末分だけ段下がりした位置より、前記カバー７内に入り込む側に延在されてなる部位に形成されている。該固定部１３は、前記バーティブラ４の端部４ｄの上面に形成された開口４ｂに係合支持される爪１３ａを有する舌片状の係合片１３ｂと、該係合片１３ｂを挟んだ位置に形成され且つ前記バーティブラ４の端部４ｄの上面、側面、下面にかけての部位に支持されてなる断面コの字状の延設部１３ｃ、１３ｃとよりなり、該延設部１３ｃ、１３ｃの下側の間には、前記ブレード部材３の保持部３ａと払拭部３ｂとの間に形成されてなる頸部３ｃの通過可能な「出し入れ口」としての切欠部１３ｄが形成されている。
【００２７】
前記支持部１４は、前記鍔部１２に対して、前記カバー７の開口部７ａから露出する側に延在されてなる部位に形成されている。該支持部１４は、前記鍔部１２から延在された舌状の弾性変形可能なる係合片１４ａと、該係合片１４ａを挟んだ位置に形成され且つ前記着脱部材１０の「一側」である鍔部１２側から「他側」である反鍔部１２側に貫通して、着脱部材１０を前記カバー７の長手方向に案内するガイド部１４ｂ、１４ｂとよりなる。前記係合片１４ａは、前記着脱部材１０の一側から他側に貫通して、該他側で係合可能なる爪１４ｃを有する舌片状に形成されてなる。
【００２８】
前記着脱部材１０は、図６、７及び図１０，１１に示すように、ナイロン、ジュラコンなどの合成樹脂材によりブロック状に形成されてなり、「一側」である鍔部１２側の面１０ａと、「他側」である反鍔部１２側の面１０ｂと、両面１０ａ、１０ｂを貫通した貫通孔１５とより形成されてなる。該貫通孔１５は、前記固定部材９より突出されてなる係合片１４ａ及びガイド部１４ｂ、１４ｂが共に挿入されるように連通して形成されている。
【００２９】
前記着脱部材１０の「一側」である鍔部１２側の面１０ａには、前記固定部材９の鍔部１２の盛り上がり部１２ｃに密接する平滑状の当接面１６と、前記固定部材９の切欠部１２ｄと略同一形状に形成されて、該切欠部１２ｄ内に係合可能なる凸状をなすＴ字状のストッパ部１７とが形成されてなる。従って、前記着脱部材１０が前記固定部材９に支持された状態では、前記切欠部１２ｄをストッパ部１７が閉じることによって、前記ブレード部材３の保持部３ａ及び頸部３ｃの着脱を阻止する機能を有する。
【００３０】
前記着脱部材１０の「他側」である鍔部１２側の反対側の面１０ｂには、前記貫通孔１５に形成された固定部材９の係合片１４ａが係合可能なる係合部１８を有する。そして、該係合部１８の上部には、指や工具等により、前記係合片１４ａへ力を加え得る斜面状の挿入用凹部１９が形成されている。符号２０は、前記貫通孔１５の前記係合部１８に対向した位置に形成されている凹部で、前記係合片１４ａの撓み代を確保している。符号２１は、前記着脱部材１０の面１０ａ、１０ｂの間にあって、前記係合部１８より面１０ａ側の部位に、該着脱部材１０の係合部１８から離脱した前記係合片１４ａが、抜け方向で再度係合可能なるように形成されている第２係合部である。
【００３１】
前記被覆部材１１は、ゴム材などよりなり、該被覆部材１１の張力により前記着脱部材１０に着脱自在なると共に該着脱部材１０を覆った状態で前記固定部材９の係合片１４ａを閉塞してなり、前記被覆部材１１は、弾力性を有する袋状より形成されてなる。
【００３２】
このように構成されたウインター用ワイパー１によれば、前記固定部材９の爪１３ａにより前記カバー７の長手方向から固定部材９に着脱自在なると共に該固定部材９に支持された状態で前記ブレード部材３の保持部３ａ及び頸部３ｃの着脱を阻止したストッパ部１７が形成されてなる着脱部材１０により、着脱部材１０を固定部材９から離脱させれば、ブレード部材３の交換が可能なる構成を維持している。
【００３３】
また、接着剤を用いずに固定部材９に着脱部材１０を確実に支持可能であるので、接着剤が、隙間からあふれ出たり、隙間を伝わってブレード部材３を他の部品に固着して外せなくなったり、製品化への総時間が多く必要とするなどの従来の不具合が一掃される。
【００３４】
また、被覆部材１１で着脱部材１０を被覆してなることにより、該防水ストッパ８の固定部材９と着脱部材１０との間に雪などが侵入しにくいことになる。
【００３５】
また、接着剤を用いずに固定部材９の支持部１４の係合片１４ａにより着脱部材１０を確実に支持可能である。着脱手段は、固定部材１０の支持部１４の係合片１４ａに対して、着脱部材１０の一側の面１０ａから他側の面１０ｂに挿入するだけで、他側の面１０ｂの係合部１８に係合されるので、係合作業が簡易である。また、被覆部材１１で固定部材９の支持部１４の係合片１４ａの爪１４ｃを閉塞してなるので、係合片１４ａの爪１４ｃが露出されていず、係合片１４ａの爪１４ｃへの操作を知らない者には、着脱部材１０をいたずらなどによって外すことを難しくしている。
【００３６】
また、凸状をなす着脱部材１０のストッパ部１７が、固定部材９の切欠部１２ｄに係合可能であるので、該係合部１２ｄから出し入れ可能なるブレード部材３をバーティブラ４内に確実に保持可能となる。また、着脱部材１０と固定部材９との間に雨水等が侵入しても、ストッパ部１７と切欠部１２ｄとが密接状態であるので、それ以上侵入できにくく、シール性が向上する。
【００３７】
また、弾性変形可能なる係合片１４ａにより固定部材９の支持部１４が形成されているので、着脱部材１０に係合した状態から離脱させるには、力を係合片１４ａに加えて、一旦係合片１４ａを撓ませる必要があり、該力を解除すれば、係合片１４ａは、再び係合する方向に撓むことになる。この作用原理を利用して、第２係合部２１を着脱部材１０の係合部１８より一側の面１０ａの位置に形成したことにより、意に反して着脱部材１０の係合部１８から係合片１４ａが外れても、一側（抜け方向）の面１０ａに移動する途中に設けた第２係合部２１に、係合片１４ａは再び係合できる。つまり、着脱部材１０は意に反して固定部材９から外れないことになる。
【００３８】
また、袋状の被覆部材１１を引っ張れば、開口が拡大し、着脱部材１０に容易に被覆が可能である。
【００３９】
以下、図１２乃至図１６の図面を参照しながら、この発明の第２実施形態について具体的に説明する。前記第１の実施形態と異なる点は、防水ストッパの構造である。前記第１実施形態と同じ構造のものは、同一符号を用いて説明する。
【００４０】
図１２において、符号３０は、ウインター用ワイパーであって、該ウインター用ワイパー３０は、自動車のフロントウインドパネルなどの払拭面２（図６参照）を払拭可能なるブレード部材３と、該ブレード部材３の保持部３ａを出し入れ自在なると共に係合した状態で保持可能に形成され且つ該ブレード部材３に弾性を付与するバーティブラ４と、前記ブレード部材３を払拭駆動可能なる駆動部材５（図１参照）と、前記バーティブラ４及び前記駆動部材５間に介在支持されてなる保持レバー機構６（図１参照）と、両端に開口部７ａが形成される筒形状をなし且つ前記バーティブラ４、前記保持レバー機構６、前記ブレード部材３の払拭部３ｂを除く部位を覆うことでそれらに雪や氷等が付着するのを防ぐ防水性を有するカバー７と、前記ブレード部材３が前記保持レバー機構６からの脱落を防止するように前記カバー７の少なくとも一端部である開口部７ａに装着され且つ水滴が前記カバー７の開口部７ａから侵入するのを防止した防水ストッパ３１とを備えてなる。
【００４１】
前記防水ストッパ３１は、固定部材３２と、着脱部材３３とより構成されてなる。
【００４２】
前記固定部材３２は、鍔部３４と、該鍔部３４より前記カバー７の内側に延在形成されてなる固定部３５と、前記鍔部３４より前記カバー７の外側に延在形成されてなる「支持手段」としての支持部３６とが、ナイロン、ジュラコンなどの合成樹脂材より一体に形成されてなる。
【００４３】
前記鍔部３４は、平板状に形成されてなり、一面３４ａは、前記カバー７の開口部７ａの端末に密接に接すると共に該開口部７ａの端末に接着剤などにより水密に閉塞してなる。また、前記一面３４ａから他面３４ｂにかけて、前記ブレード部材３の保持部３ａ及び該保持部３ａと払拭部３ｂとの間に形成されてなる頸部３ｃが通過可能なＴ字形の「出し入れ口」である切欠部３４ｄが形成されている。
【００４４】
前記固定部３５は、前記鍔部３４に対して、前記カバー７の開口部７ａの端末分だけ段下がりした位置より、前記カバー７内に入り込む側に延在されてなる部位に形成されている。該固定部３５は、前記バーティブラ４の端部４ａの上面に形成された開口４ｂに係合支持される爪３５ａを有する舌片状の係合片３５ｂと、該係合片３５ｂを挟んだ位置に形成され且つ前記バーティブラ４の端部４ａの上面、側面、下面にかけての部位に支持されてなる断面コの字状の延設部３５ｃ、３５ｃとよりなり、該延設部３５ｃ、３５ｃの下側の間には、前記ブレード部材３の保持部３ａと払拭部３ｂとの間に形成されてなる頸部３ｃの通過可能な「出し入れ口」としての切欠部３５ｄが形成されている。
【００４５】
前記支持部３６は、前記鍔部３４に対して、前記カバー７の開口部７ａから露出する側に延在されてなる部位に形成されてなると共に上下に貫通する貫通孔３６ａが形成されていて、ビス３７が通過可能である。
【００４６】
前記着脱部材３３は、ナイロン、ジュラコンなどの合成樹脂材によりブロック状に形成されてなり、「一側」である鍔部３４側の面３３ａには、前記鍔部３４の切欠部３４ｃ内に係合可能なる凸状をなすストッパ部３８が形成されてなる。着脱部材３３の「他側」である反鍔部３４側の面３３ｂの上面３３ｃは、前記支持部３６を挟むように形成されていて、該上面３３ｃには、前記ビス３７が螺結可能なる下孔３９が形成されている。
【００４７】
このように構成されたウインター用ワイパー３０によれば、前記ビス３７を弛めて取り外すことにより、固定部材３２に対して着脱部材３３を取り外すことにより、ブレード部材３の交換が可能なる構成を維持している。
【００４８】
また、接着剤を用いずに固定部材３２に着脱部材３３を確実に支持可能であるので、接着剤が、隙間からあふれ出たり、隙間を伝わってブレード部材３を他の部品に固着して外せなくなったり、製品化への総時間が多く必要とするなどの従来の不具合が一掃される。
【００４９】
また、接着剤を用いずに固定部材３２の支持部３６により着脱部材３３を確実に支持可能である。着脱手段は、固定部材３２の支持部３６の貫通孔３６ａを通過させたビス３７により、着脱部材３３の下孔３９に螺合させるだけで、支持されるので、着脱作業が簡易である。
【００５０】
また、凸状をなす着脱部材３３のストッパ部３８が、固定部材３２の切欠部３４ｃに係合可能であるので、該係合部３４ｃから出し入れ可能なるブレード部材３をバーティブラ４内に確実に保持可能となる。また、着脱部材３３と固定部材３２との間に雨水等が侵入しても、ストッパ部３８と切欠部３４ｃとが密接状態であるので、それ以上侵入できにくく、シール性が向上する。
【００５１】
前記実施形態は、自動車用のウインター用ワイパーに関して説明したが、かかる自動車用であることに限られるものではなく、航空機、船舶などの乗り物のフロントウインドパネル、サイドウインドパネル、リアウインドパネル、サンルーフなど、窓を通して外などを見る目的の部材に付着した雨水や雪やみぞれ、ゴミなどを払拭することが可能なるものであれば、良い。また、ウインター用ワイパーの「ウインター」とは、所謂冬季のみならず、寒冷地など、雪が付着する可能性のあるところで用いられるワイパーの総称として用いたものである。
【００５２】
また、前記ブレード部材３を払拭駆動可能なる駆動部材５は、図示しないワイパーモータの駆動軸に連結され且つ前記払拭面２に対してほぼ直交する方向に延在したワイパー軸と、該ワイパー軸に取付けたアームヘッドと、該アームヘッドにワイパー軸に対してほぼ直交するヒンジピンにより回動可能に取付けたワイパーアームと、該ワイパーアーム及びアームヘッドに介装されて前記ワイパーアームを払拭面２側に常時押圧する弾性部材とよりなる周知の構成部材であって、払拭面２に対して面方向に往復運動を行うことにより、ブレード部材３の払拭部３ｂが払拭面２上を払拭する。
【００５３】
【発明の効果】
請求項１の発明によれば、前記固定部材の支持手段により、前記カバーの長手方向から固定部材に着脱自在なると共に該固定部材に支持された状態で前記ブレード部材の保持部の着脱を阻止したストッパ部が形成されてなる着脱部材によりなるので、着脱部材を固定部材から離脱させれば、ブレード部材の交換が可能なる構成を維持している。また、接着剤を用いずに固定部材に着脱部材を確実に支持可能であるので、接着剤が、隙間からあふれ出たり、隙間を伝わってブレード部材を他の部品に固着して外せなくなったり、製品化への総時間が多く必要とするなどの従来の不具合が一掃される。更に、接着剤を用いずに固定部材の支持手段が着脱部材に支持させるだけで、確実に支持可能である。しかも、固定部材の支持手段に対して一側から他側に挿入するだけで、他側に支持されるので、取付作業が簡易である。
【００５５】
請求項２に記載の発明によれば、弾性変形可能なる係合片により、固定部材の支持手段が形成されているので、着脱部材に係合した状態から離脱させるには、力を係合片に加えて、一旦係合片を撓ませる必要があり、該力を解除すれば、係合片は、再び係合する方向に撓むことになる。この作用原理を利用して、第２係合部を着脱部材の係合部より一側の位置に形成したことにより、意に反して着脱部材の係合部から係合片が外れても、一側（抜け方向）に移動する途中に設けた第２係合部に、係合片は再び係合できる。つまり、着脱部材は意に反して固定部材から外れないことになる。
【００５６】
請求項３に記載の発明によれば、接着剤を用いずに締結具により着脱部材を確実に支持可能であるので、支持作業が簡易である。
【００５７】
請求項４に記載の発明によれば、被覆部材で固定部材の支持手段を閉塞してなるので、支持手段が露出されていず、支持手段への操作を知らない者には、着脱部材をいたずらなどによって外すことを難しくしている。また、被覆部材で着脱部材を被覆してなることにより、該防水ストッパの固定部材と着脱部材との間に雪などが侵入しにくいことになる。
【００５８】
請求項５に記載の発明によれば、凸状をなす着脱部材のストッパ部が、固定部材の出し入れ口に係合可能であるので、該出し入れ口から出し入れ可能なるブレード部材をバーティブラ内に確実に保持可能となる。また、着脱部材と固定部材との間に雨水等が侵入しても、ストッパ部と出し入れ口とが密接状態であるので、それ以上侵入できにくく、シール性が向上する。
【００５９】
請求項６に記載の発明によれば、袋状の被覆部材を引っ張れば開口が拡大し、着脱部材に容易に被覆が可能である。
