【発明の属する技術分野】
本発明は、自動車のステアリングコラム等に付設されて方向指示器として用いられるターンシグナルスイッチ装置に関する。
【０００２】
【従来の技術】
従来のターンシグナルスイッチ装置の図面を説明すると、図９は従来のターンシグナルスイッチ装置の分解斜視図、図１０は従来のターンシグナルスイッチ装置の要部の縦断面図、図１１は従来のターンシグナルスイッチ装置に係り、第１ケースに操作レバー等を組み込んだ状態を示す平面図、図１２は従来のターンシグナルスイッチ装置に係り、中立位置の状態を示す動作説明図、図１３は従来のターンシグナルスイッチ装置に係り、動作位置の状態を示す動作説明図、図１４は従来のターンシグナルスイッチ装置に係り、動作状態を示す説明図である。
【０００３】
次に、従来のターンシグナルスイッチ装置の構成を図９〜図１４に基づいて説明すると、合成樹脂の成型品からなる第１，第２ケース１０１，１０２は、スナップ結合等の手段を用いて一体化され、図示せぬコラムカバーやコンビスイッチ等のステータ部材に固定されるようになっている。
そして、第１ケース１０１の内面には、Ｖ字状のカム面１１０が設けられていると共に、この第１，第２ケース１０１，１０２とでハウジングが構成されている。
【０００４】
この第１ケース１０１の底面には、プリント基板１１１が取り付けられており、このプリント基板１１１上には、可動接点１１４，１１５をそれぞれ保持した一対の摺動子受け体１１２，１１３が摺動可能に配置されている。
そして、このプリント基板１１１には、可動接点１１４，１１５と接離する図示せぬ固定接点が形成されており、この固定接点と可動接点１１４とで第１スイッチＳ３が形成されると共に、固定接点と可動接点１１５とで第２スイッチＳ４が形成されている。
【０００５】
また、第１スイッチＳ３は後方部に配置されると共に、第２スイッチＳ４は、第２スイッチＳ３から大きく間隔を置いて前方部に配置されている。
そして、一方の摺動子受け体１１２は、後述する操作レバー１０３の左折、又は右折方向への回動操作により駆動されて、図示せぬ左折、又は右折用ランプが点滅動作を行うようになっていると共に、他方の摺動子受け体１１３は、後述する操作レバー１０３の上下方向への揺動操作により駆動され、図示せぬビーム用ランプが点灯動作を行うようになっている。
【０００６】
合成樹脂の成型品からなる略平板状のキャンセルレバーである第１のレバー部材１０４は、第１，第２長孔１０４ａ、１０４ｂと、断面形状が半円形をなしたカム部１０４ｃとを有し、この第１のレバー部材１０４は、第２ケース１０２に設けられた突起（図示せず）が第１長孔１０４ａに挿通されて、この突起に沿ってスライド移動可能であると共に、回転可能となっている。
【０００７】
合成樹脂の成型品からなる平板状の第２のレバー部材１０５は、中央部に設けられた孔１０５ａと、この孔１０５ａの両側に設けられた第１，第２の開口部１０５ｂ、１０５ｃと、一端側に設けられた連結ピン１０５ｄとを有する。
そして、この第２のレバー部材１０５は、連結ピン１０５ｄが第２長孔１０４ｂに挿通すると共に、カム部１０４ｃが第１の開口部１０５ｂに挿通した状態で、第１のレバー部材１０４上に重ね合わされている。
この時、ここでは図示しないが、第２ケース１０２に設けられた支軸が孔１０５ａに挿入されて、第２のレバー部材１０５が支軸を中心として回転可能となっている。
【０００８】
捻りコイルバネ１０６は、第２ケース１０２に取り付けられ、一端部が第１のレバー部材１０４に係合されて、第１のレバー部材１０４を長手方向に弾性付勢している。
操作レバー１０３は、第１，第２ケース１０１，１０２に回転可能に保持されると共に、作動部材１０７，ホルダー１０８，及び可動部材１０９等を具備している。
【０００９】
合成樹脂の成型品からなる作動部材１０７は、両側面に設けられた凹部１０７ａと、下方に突出する突起１０７ｂとを有し、この作動部材１０７は、その前端部が操作レバー１０３の根本部分に固定されると共に、突起１０７ｂが摺動子受け体１１３に係合して、作動部材１０７の動きに伴って摺動子受け体１１３が可動して、第２スイッチＳ４が操作されるようになっている。
【００１０】
合成樹脂の成型品からなるホルダー１０８は、両側面から前方に延びる一対の突出片１０８ａと、突出片１０８ａの内側に設けられた突起１０８ｂとを有し、この一対の突出片１０８ａ間には、作動部材１０７が配置されると共に、凹部１０７ａに突起１０８ｂがスナップ嵌合されて、作動部材１０７がホルダー１０８に対して上下方向への揺動操作可能に取り付けられている。
【００１１】
また、ホルダー１０８は、先端部に設けられた山形のカム面１０８ｃと、上下面に設けられた一対の支軸１０８ｄ、１０８ｅと、下面に設けられた突起１０８ｆとを有する。
そして、このホルダー１０８は、支軸１０８ｄ、１０８ｅのそれぞれが第１，第２ケース１０１，１０２の凹部（図示せず）に嵌合されて、回動可能に取り付けられると共に、突起１０８ｆが摺動子受け体１１２に係合（図１０参照）して、ホルダー１０８の動きに伴って摺動子受け体１１２が可動して、第１スイッチＳ３が操作されるようになっている。
【００１２】
合成樹脂の成型品からなる可動部材１０９は、脚部１０９ａと駆動部１０９ｂを有し、この可動部材１０９は、脚部１０９ａがホルダー１０８に形成された開口部１０８ｇに挿入され、脚部１０９ａがホルダー１０８にスナップ嵌合されて、ホルダー１０８に揺動可能に取り付けられている。
そして、駆動部１０９ｂは、ホルダー８の上面に沿って前方へ延びており、駆動部１０９ｂに設けられた受け部１０９ｃが第２のレバー部材１０５の第２の開口部１０５ｃに挿入された状態となっている。
【００１３】
また、図１０に示すように、ホルダー１０８の後端部には、合成樹脂の成型品からなる第１の駆動体１２４がスライド移動可能に収納されており、この第１の駆動体１２４の先端部は、この第１の駆動体１２４と可動部材１０９の脚部１０９ａとの間に介在されたスプリング１２５の反発力により、第１ケース１０１のカム面１１０に圧接されると共に、可動部材１０９の脚部１０９ａは、ホルダー１０８の内面に圧接された状態となっている。
【００１４】
上述したように、操作レバー１０３に固定された作動部材１０７とホルダー１０８とは、凹部１０７ａと突起１０８ｂの嵌合部分で回転可能に連結されており、また、ホルダー１０８と第１，第２ケース１０１，１０２とは、支軸１０８ｄ、１０８ｅの嵌合部分で、回転可能に連結されている。
【００１５】
従って、操作レバー１０３を左折、又は右折の指示位置へ回動操作した場合、操作レバー１０３と作動部材１０７，及びホルダー１０８の三者は、支軸１０８ｄ、１０８ｅを軸として矢印Ａ方向（図９参照）に回転するが、操作レバー１０３を指示位置と直交する矢印Ｂ方向へ回動操作した場合、操作レバー１０３と作動部材１０７は、ホルダー１０８に対して、両突起１０８ｂを結ぶ直線を回転軸として垂直方向へ所定角度だけ回転する。
【００１６】
また、図１０に示すように、作動部材１０７の後端部には、スプリング１２６を介して第２の駆動体１２７がスライド可能に保持されており、第２の駆動体１２７の先端部は、ホルダー１０８の内部に形成されたカム面１０８ｈに圧接している。
そして、カム面１０８ｈ上を移動する第２の駆動体１２７の摺動方向は、第１の駆動体１２４と直交しており、操作レバー１０３を矢印Ｂ方向（図９参照）に回動操作した時、作動部材１０７が回動して、第２の駆動体１２７がカム面１０８ｈ上を摺動するようになっている。
【００１７】
次に、従来のターンシグナルスイッチ装置の動作を説明すると、操作レバー１０３が中立位置にある時、第１の駆動体１２４は、カム面１１０の中央部の谷部に位置すると共に、第１のレバー部材１０４のカム部１０４ｃは、ホルダー１０８のカム面１０８ｃの頂点で当接しており、図１２に示すように、第１のレバー部材１０４は、捻りコイルバネ１０６の付勢力に抗して前進している。
従って、第１のレバー部材１０４の当接部１０４ｄは、ハンドルに連動して回転するキャンセル突起１２８の回転軌跡外に位置しており、この状態でハンドルを回転しても、キャンセル突起１２８は、第１のレバー部材１０４の当接部１０４ｄに当接せず、操作レバー１０３は、中立位置に維持される。
【００１８】
次に、操作レバー１０３をこの中立位置から図１１の矢印Ａ１方向，或いは矢印Ａ２方向の何れかの方向に回転すると、第１の駆動体１２４の先端部は、カム面１１０上を摺動して、ロック部１１０ｂに係止され、カム面１１０の斜面を乗り越える際にクリック感が生起される。
【００１９】
ここで、例えば、操作レバー１０３を図１１の矢印Ａ２方向に回動すると、操作レバー１０３に連動してホルダー１０８と可動部材１０９も同方向へ回転し、それに伴ってカム面１０８ｃの頂部がカム部１０４ｃから外れるため、図１３に示すように、第１のレバー部材１０４は、捻りコイルバネ１０６の腕部の弾性力を受けて第１，第２長孔１０４ａ、１０４ｂの長手方向に沿って後退（操作レバー１０３に対して後方側）し、当接部１０４ｄがキャンセル突起１２８の回転軌跡内に進出する。
【００２０】
また、操作レバー１０３の矢印Ａ２方向への回転に伴い、ホルダー１０８の安定位置に保持された可動部材１０９の受け部１０９ｃは、第２のレバー部材１０５の第２の開口部１０５ｃ内を変位し、図１３に示すように、受け部１０９ｃは、第２の開口部１０５ｃの一方の湾曲部１０５ｅと当接する。
更に、操作レバー１０３の矢印Ａ２方向への回転に伴い、ホルダー１０８の突起１０８ｆが一方の摺動子受け体１１２を駆動するため、スイッチＳ３の操作が行われて接点の切換が行われ、図示せぬ右折用のランプが点滅動作する。
【００２１】
また、図１３に示す右折状態で、ハンドルが矢印Ｃ方向（逆方向）に回転操作されると、そのリターン動作中にキャンセル突起１２８が第１のレバー部材１０４の当接部１０４ｄに突き当たる。
その結果、第１のレバー部材１０４が軸部（図示せず）を中心に時計回り方向に回転し、それに伴って、第１のレバー部材１０４に連結された第２のレバー部材１０５が前記軸部を中心に時計回り方向に回転するため、第２のレバー部材１０５の第２の開口部１０５ｃは、同図の上方へ回動変位する。
【００２２】
これにより、第２の開口部１０５ｃの湾曲部１０５ｅが可動部材１０９の受け部１０９ｃを上方へ押圧し、この押圧力が可動部材１０９を介してホルダー１０８に伝達されるため、ホルダー１０８に保持された第１の駆動体１２４の先端部は、カム面１１０のロック部１１０ｂから外れて中央の谷部１１０ａへと移行し、操作レバー１０３と第１，第２のレバー部材１０４，１０５は、図１２に示す中立位置に自動復帰する。
【００２３】
また、図１３に示す右折状態で、操作レバー１０３に自動復帰を阻止する何らかの力が作用した場合、例えば、操作レバー１０３を押さえながらハンドルが逆方向に回転操作されると、上記したように第２のレバー部材１０５が軸部を中心に時計回り方向に回転しようとするが、操作レバー１０３が押さえられているため、ホルダー１０８は回転せず、第２の開口部１０５ｃと受け部１０９ｃとの当接部分に過大な負荷が発生する。
【００２４】
このような過負荷が生じた場合、図１４に示すように、第２のレバー部材１０５の回転方向の分圧によって、受け部１０９ｃが湾曲部１０５ｅに沿って押圧され、可動部材１０９がスプリング１２５の反発力に抗して、図１４の二点鎖線で示す安定位置から実線で示す退避位置へと揺動するため、第１，第２のレバー部材１０４，１０５は、受け部１０９ｃに妨げられることなく回転できる。
そして、キャンセル突起１２８が第１のレバー部材１０４の当接部１０４ｄを通過すると、可動部材１０９は、スプリング１２５の反発力によって退避位置から安定位置へと自動復帰するため、図１３に示す右折状態に維持される。
【００２５】
一方、操作レバー１０３を指示位置と直交する方向（図９の矢印Ｂ方向）に回動すると、操作レバー１０３と作動部材７が第１，第２ケース１０１，１０２とホルダー１０８に対し、突起１０８ｂを結ぶ直線を回転軸として垂直方向へ所定角度だけ回転し、それに伴って、第２の駆動体１２７の先端部がホルダー１０８のカム面１０８ｈ上を摺動し、カム面８ｈを乗り越える際にクリック感が生起される。
そして、操作レバー１０３の回動に伴い、作動部材１０７の突起１０７ｂがもう一方の摺動子受け体１１３を駆動するため、スイッチＳ４の操作が行われて接点の切換が行われ、ビーム切換やパッシング動作が行われる。
【００２６】
【発明が解決しようとする課題】
従来のターンシグナルスイッチ装置は、キャンセルレバー１０４とレバー部材１０５とが平面的に重ね合わされた構成であるため、その配置が長くなり、このため、奥行き方に大型となるという問題がある。
また、操作レバー１０３を復帰させるために、ホルダー１０８と可動部材１０９を必要とし、部品点数が多くなると共に、組立性が悪くなってコスト高になるばかりか、可動部材１０９の収納スペースを必要とし、大型になるという問題がある。
【００２７】
そこで、本発明は奥行き方向が小型で、組立性の良好な安価なターンシグナルスイッチ装置を提供することを目的とする。
【００２８】
【課題を解決するための手段】
上記課題を解決するための第１の解決手段として、第１カム面を設けた直立壁を有するハウジングと、このハウジングに回動可能に支持された操作レバーと、前記第１カム面と協働して前記操作レバーを中立位置と動作位置に保持する第１の駆動体と、この第１の駆動体を前記第１カム面に向けて付勢する第１スプリングと、ハンドル側のキャンセル突起に当接して回転動作されるキャンセルレバーと、このキャンセルレバーの回転動作を前記操作レバーに伝達して、前記操作レバーを動作位置から中立位置に復帰するレバー部材とを備え、前記直立壁には、前記カム面の形成面と反対側の面から突出する軸部を設け、前記レバー部材は、前記直立壁に沿って延び、前記軸部によって回転可能に支持された基部と、この基部の一端側に設けられ、前記キャンセルレバーに係合した第１係合部と、前記基部の他端側に設けられた第２係合部とを有し、前記キャンセルレバーの回転動作時、前記キャンセルレバーが前記第１係合部を移動させると共に、この第１係合部の移動によって、前記レバー部材が前記軸部を中心として回転し、前記レバー部材の回転動作によって、前記第２係合部を介して、前記操作レバーを動作位置から中立位置に復帰するようにした構成とした。
この構成によって、キャンセルレバーに対してレバー部材が直立状態で配置された構成となって、従来に比して、奥行き方向に小さくでき、小型のターンシグナルスイッチ装置を提供できる。
【００２９】
また、第２の解決手段として、前記レバー部材は、前記直立壁を上下方向に横切るように配設され、前記第１係合部が下方に位置して前記キャンセルレバーに係合すると共に、前記第２係合部が上方に位置した構成とした。
この構成によって、レバー部材の第１，第２係合部を上下に分離できて、構成が簡単で、動作の確実なものが得られる。
【００３０】
また、第３の解決手段として、前記キャンセルレバーは、第１，第２の長孔を有し、前記第１の長孔内には、前記第１係合部が挿入されると共に、前記第２の長孔内には、前記直立壁から延びる突起が挿入されて、前記キャンセルレバーは、前記第１，第２の長孔形成方向にスライド可能であると共に、前記突起を中心として回転可能とした構成とした。
この構成によって、キャンセルレバーへのレバー部材と直立壁の係合が簡単となり、組立性が良く、且つ、スペースファクタが良好で、小型化が図れる。
【００３１】
また、第４の解決手段として、前記操作レバーと連動し、前記ハウジングに回動可能に支持されたホルダーを有し、このホルダーには、前記第１駆動体と前記第１スプリングが保持されて、前記ホルダーが中立位置と動作位置に移動可能であると共に、前記ホルダーは、前記第２係合部と係合可能な突部と、第１のスイッチを操作する第１腕部とを有し、前記操作レバーの回動動作に連動して、前記ホルダーが回動して動作位置になると共に、前記第１腕部によって前記第１のスイッチが操作され、前記キャンセルレバーの回転時、前記キャンセルレバーによって回転される前記レバー部材の前記第２係合部が前記突部を引っかけて前記ホルダーを回動し、前記ホルダーと前記操作レバーが動作位置から中立位置に復帰するようにした構成とした。
この構成によって、レバー部材がホルダーを動作位置から中立位置に復帰させるため、従来の可動部材１０９が不要となり、部品点数を少なくできると共に、組立性が良く、安価で、且つ、小型のものが得られる。
また、ホルダーは、第２係合部と係合可能な突部を設ければ良く、その構成が簡単にできると共に、ホルダーが第１のスイッチを操作するようにしたため、方向指示器としての操作を確実に行うことができる。
【００３２】
また、第５の解決手段として、前記ホルダーと前記キャンセルレバーの一方には、カム部を設けると共に、他方には、前記カム部と係脱可能な受け部を設け、前記キャンセルレバーが捻りコイルバネにより付勢され、前記操作レバーの回動による前記ホルダーの回動時、前記カム部と前記受け部との係合が外れて、前記キャンセルレバーが前記捻りコイルバネによって前記キャンセル突起の回転軌跡内に位置し、前記キャンセルレバーの回転時、前記ホルダーが動作位置から中立位置に復帰すると共に、前記カム部と前記受け部が係合状態に復帰し、前記キャンセルレバーが前記捻りコイルバネに抗して、前記キャンセル突起の回転軌跡外に位置するようにした構成とした。
この構成によって、キャンセルレバーとホルダーとの係脱動作がカム部と受け部によって行うことができて、その構成が簡単であると共に、捻りコイルバネによって、その動作の確実なものが得られる。
【００３３】
また、第６の解決手段として、前記ホルダーに設けられた第２カム面と協働して前記操作レバーを中立位置と動作位置に保持する第２の駆動体と、この第２の駆動体を前記第２カム面に向けて付勢する第２スプリングと、前記ホルダーの回動方向に対して直交する方向に回動可能で、前記操作レバーと連動可能な作動部材を備え、この作動部材には、前記第２駆動体と前記第２スプリングが保持されて、前記作動部材が中立位置と動作位置に移動可能であると共に、前記作動部材は、第２のスイッチを操作する第２腕部を有し、前記操作レバーの回動動作に連動して、前記作動部材が回動して動作位置になると共に、前記第２腕部によって前記第２のスイッチが操作され、前記操作レバーの回動動作の解除時、前記作動部材と前記操作レバーが動作位置から中立位置に自動復帰するようにした構成とした。
この構成によって、第２のスイッチは、ビーム切換やパッシング動作に適用でき、多機能のものが得られる。
【００３４】
また、第７の解決手段として、前記第１，第２のスイッチが隣り合わせに配置された構成とした。
この構成によって、第１，第２のスイッチが小さいスペースで配置できて、奥行きの小さく、小型のものが得られる。
【００３５】

【００３８】
そして、第１、第２ケース１、２は、第２ケース２が下部に位置した状態で組み合わされると共に、この第１，第２ケース１，２とでハウジングＨが構成されている。
また、第１，第２ケース１，２が組み合わされた際、保持部１ａ、２ｃは、互いに上下に対向した状態となっている。
【００３９】
この第２ケース２の底面には、プリント基板１１が取り付けられており、このプリント基板１１上には、可動接点１４，１５をそれぞれ保持した一対の摺動子受け体１２，１３が摺動可能に配置されている。
そして、このプリント基板１１には、可動接点１４，１５と接離する図示せぬ固定接点が形成されており、この固定接点と可動接点１４とで第１のスイッチＳ１が形成されると共に、固定接点と可動接点１５とで第２のスイッチＳ２が形成されている。

【００４１】
合成樹脂の成型品からなる略平板状のキャンセルレバーである第１のレバー部材４は、第１，第２長孔４ａ、４ｂと、断面形状が半円形をなしたカム部４ｃと、下部に設けられたＬ字状の掛け止め部４ｄと、後端部に位置する当接部４ｅとを有し、この第１のレバー部材４は、一部が第２ケース２の基部２ａ上に配置され、第２ケース２に設けられた突起２ｇが第２長孔４ｂに挿通されて、第１のレバー部材４は、突起２ｇに沿ってスライド移動可能であると共に、回転可能となっている。
そして、第１のレバー部材４が取り付けられた際、当接部４ｅが第１ケース１の切り欠き部１ｅから後方に突出した状態となっている。
【００４２】
合成樹脂の成型品からなる平板状の第２のレバー部材５は、中央部に孔５ａを有する平板状の基部５ｂと、この基部５ｂの一端側である下部から後方に折り曲げられた折り曲げ部５ｃと、この折り曲げ部５ｃから下方に突出した凸部からなる第１係合部５ｄと、基部５ｂの他端側である上部から前方に折り曲げられて、二股状をなした第２係合部５ｅとを有する。

【００４６】
合成樹脂の成型品からなるホルダー８は、両側面から前方に延びる一対の突出片８ａと、突出片８ａの内側に設けられた突起８ｂと、突出片８ａ間の上下から前方に突出して設けられた一対の突出片８ｃと、この突出片８ｃの自由端部に設けられた突起８ｄと、二対の突出片８ａ、８ｃとに囲まれた底部に設けられたカム面８ｅ（図２参照）と、上部に設けられた凸条部からなる突部８ｆと、後面側に設けられた凹部からなる収納部８ｇと、下部の後部側から下方に突出して設けられた受け部８ｈと、下部の中央部から下方に突出して設けられた腕部８ｊとを有する。
【００４７】
そして、この二対の突出片８ａ、８ｃ間には、作動部材７が配置されると共に、凹部７ａに突起８ｂがスナップ嵌合されて、作動部材７がホルダー８に対して上下方向への揺動操作可能に取り付けられている。
また、このホルダー８は、突起８ｄのそれぞれが第１，第２ケース１，２の保持部１ａ、２ｃに嵌合されて、回動可能に取り付けられると共に、腕部８ｊが摺動子受け体１２に係合して、ホルダー８の動きに伴って摺動子受け体１２が可動して、第１スイッチＳ１が操作されるようになっている。
【００４８】
また、図２に示すように、ホルダー８の後端部の収納部８ｇには、合成樹脂の成型品からなる第１の駆動体２４がスライド移動可能に収納されており、この第１の駆動体２４の先端部は、収納部８ｇに収納されたスプリング２５の反発力により、直立壁２ｅに設けたカム面１０に圧接されている。
【００４９】
上述したように、操作レバー３に固定された作動部材７とホルダー８とは、凹部７ａと突起８ｂの嵌合部分で回転可能に連結されており、また、ホルダー８と第１，第２ケース１，２とは、突起８ｄと保持部１ａ、２ｃの嵌合部分で、回転可能に連結されている。
【００５０】
従って、操作レバー３を左折、又は右折の指示位置へ回動操作した場合、操作レバー３と作動部材７，及びホルダー８の三者は、突起８ｄを軸として矢印Ａ方向（図３参照）に回転するが、操作レバー３を指示位置と直交する矢印Ｂ方向（図２参照）へ回動操作した場合、操作レバー３と作動部材７は、ホルダー８に対して、両突起８ｂを結ぶ直線を回転軸として垂直方向へ所定角度だけ回転する。
【００５１】
また、図２に示すように、作動部材７の後端部の収納部７ｃには、スプリング２６を介して第２の駆動体２７がスライド可能に保持されており、第２の駆動体２７の先端部は、ホルダー８の内部に形成されたカム面８ｅに圧接している。
そして、カム面８ｅ上を移動する第２の駆動体２７の摺動方向は、第１の駆動体２４と直交しており、操作レバー３を矢印Ｂ方向（図２参照）に回動操作した時、作動部材７が回動して、第２の駆動体２７がカム面８ｅ上を摺動するようになっている。
【００５２】
また、ホルダー８が取り付けられた際、受け部８ｈと第１のレバー部材４のカム部４ｃとは係脱可能となり、受け部８ｈとカム部４ｃの係合が外れた時は、第１のレバー部材４は、捻りコイルバネ６の付勢によって、後方側に突出した状態となる。
なお、この実施例では、第１のレバー部材（キャンセルレバー）４にカム部４ｃを、また、ホルダー８に受け部８ｈを設けたもので説明したが、第１のレバー部材（キャンセルレバー）４に受け部を、また、ホルダー８にカム部を設けても良い。
【００５３】
次に、本発明のターンシグナルスイッチ装置の動作を説明すると、操作レバー３が中立位置にある時、第１の駆動体２４は、カム面１０の中央部の谷部１０ａに位置すると共に、第１のレバー部材４のカム部４ｃには、ホルダー８の受け部８ｈの頂点で当接しており、図５，図６に示すように、第１のレバー部材４は、捻りコイルバネ６の付勢力に抗して前方方向に移動している。
従って、第１のレバー部材４の当接部４ｅは、ハンドルに連動して回転するキャンセル突起２８の回転軌跡外に位置しており、この状態でハンドルを回転しても、キャンセル突起２８は、第１のレバー部材４の当接部４ｅに当接せず、操作レバー３は、中立位置に維持される。
【００５４】
次に、操作レバー３を、図５，図６に示す中立位置から図３の矢印Ａ１方向，或いは矢印Ａ２方向の何れかの方向に回転すると、第１の駆動体２４の先端部は、カム面１０上を摺動して、ロック部１０ｂに係止され、カム面１０の斜面を乗り越える際にクリック感が生起される。
【００５５】
ここで、例えば、操作レバー３を図３の矢印Ａ２方向に回動すると、操作レバー３に連動してホルダー８も同方向へ回転し、それに伴って受け部８ｈの頂部がカム部４ｃから外れるため、図７，図８に示すように、第１のレバー部材４は、捻りコイルバネ６の腕部６ｃの弾性力を受けて第１，第２長孔４ａ、４ｂの長手方向（形成方向）に沿って後退（操作レバー３に対して後方側）し、当接部４ｅがキャンセル突起２８の回転軌跡内に進出する。
【００５６】
また、操作レバー３の矢印Ａ２方向への回転に伴い、ホルダー８の腕部８ｊが一方の摺動子受け体１２を駆動するため、第１のスイッチＳ１の操作が行われて接点の切換が行われ、図示せぬ右折用のランプが点滅動作する。
更に、この時、ホルダー８の突部８ｆは、第１のレバー部材５の第２係合部５ｅに近接した状態となる。
【００５７】
また、図７，図８に示す右折状態で、ハンドルが矢印Ｃ方向（逆方向）に回転操作されると、そのリターン動作中にキャンセル突起２８が第１のレバー部材４の当接部４ｅに突き当たる。
その結果、第１のレバー部材４が直立壁２ｅの突起２ｇを中心に時計回り方向に回転し、それに伴って、第１のレバー部材４に係合された第２のレバー部材５が軸部２ｆを中心に時計回り方向に回転するため、第２のレバー部材５の第２係合部５ｅは、ホルダー８の突部８ｆと係合して、ホルダー８を回転する。
【００５８】
これにより、ホルダー８に保持された第１の駆動体２４の先端部は、カム面１０のロック部１０ｂから外れて中央の谷部１０ａへと移行し、操作レバー３と第２のレバー部材５は、図５，６に示す中立位置に自動復帰する。
また、ホルダー８が中立位置に戻る際、受け部８ｈが第１のレバー部材４のカム部４ｃと係合して、第１のレバー部材４を捻りコイルバネ６に抗して前方方向に押し戻されて、第１のレバー部材４も同様に、図５，６に示す中立位置に自動復帰する。
【００５９】
また、図７，図８に示す右折状態で、操作レバー３に自動復帰を阻止する何らかの力が作用した場合、例えば、操作レバー３を押さえながらハンドルが逆方向に回転操作されると、第１のレバー部材（キャンセルレバー）４は、キャンセル突起２８によって押圧されて、突起２ｇを中心として、第２係合部５ｅが突部８ｆにぶつかるまで僅かに回転すると共に、回転後に、第１のレバー部材４は、突起２ｇと第１係合部５ｄをガイドにして前方向（操作レバー３方向）にスライド移動して、キャンセル突起２８の回転軌跡外に退避する。
【００６０】
このため、第１のレバー部材４とホルダー８との間には、過大な負荷が発生することなく、右折状態を維持した状態で、ハンドルの操作ができる。
そして、キャンセル突起２８が第１のレバー部材４の当接部４ｅを通過すると、第１のレバー部材４はスプリング２５の反発力によって退避位置からキャンセル突起２８の回転軌跡内の位置に自動復帰して、キャンセル可能な状態に戻る。
【００６１】
一方、操作レバー３を指示位置と直交する方向（図２の矢印Ｂ方向）に回動すると、操作レバー３と作動部材７が第１，第２ケース１，２とホルダー８に対し、突起８ｂを結ぶ直線を回転軸として垂直方向へ所定角度だけ回転し、それに伴って、第２の駆動体２７の先端部がホルダー８のカム面８ｅ上を摺動し、カム面８ｅを乗り越える際にクリック感が生起される。
そして、操作レバー３の回動に伴い、作動部材７の腕部７ｂがもう一方の摺動子受け体１３を駆動するため、第２のスイッチＳ２の操作が行われて接点の切換が行われ、ビーム切換やパッシング動作が行われる。
【００６２】
【発明の効果】
本発明のターンシグナルスイッチ装置において、ハウジングＨの直立壁２ｅには、カム面１０の形成面と反対側の面から突出する軸部２ｆを設け、レバー部材５の基部５ｂが直立壁２ｅに沿って延びて、軸部２ｆによって回転可能に支持されると共に、基部５ｂの一端側に設けられ第１係合部５ｄがキャンセルレバー４に係合し、そして、キャンセルレバー４の回転動作時、キャンセルレバー４が第１係合部５ｄを移動させると共に、この第１係合部５ｄの移動によって、レバー部材５が軸部２ｆを中心として回転し、レバー部材５の回転動作によって、基部５ｂの他端側に設けられた第２係合部５ｅを介して、操作レバー３を動作位置から中立位置に復帰するようにしたため、キャンセルレバー４に対してレバー部材５が直立状態で配置され、従来に比して、奥行き方向に小さくでき、小型のターンシグナルスイッチ装置を提供できる。

At the same time, the other slider receiver 113 is driven by a swinging operation of an operation lever 103, which will be described later, in a vertical direction so that a beam lamp (not shown) performs a lighting operation.
[0006]
The first lever member 104, which is a substantially flat cancel lever made of a synthetic resin molded product, has first and second elongated holes 104a and 104b and a cam portion 104c having a semicircular cross section. The first lever member 104 has a protrusion (not shown) provided in the second case 102 inserted into the first elongated hole 104a, and is slidable and rotatable along the protrusion. It has become.
[0007]

The second lever member 105 is overlapped on the first lever member 104 with the connecting pin 105d inserted through the second elongated hole 104b and the cam portion 104c inserted through the first opening 105b. Has been.
At this time, although not shown here, a support shaft provided in the second case 102 is inserted into the hole 105a, so that the second lever member 105 can rotate around the support shaft.
[0008]
The torsion coil spring 106 is attached to the second case 102 and has one end engaged with the first lever member 104 to elastically bias the first lever member 104 in the longitudinal direction.
The operation lever 103 is rotatably held by the first and second cases 101 and 102, and includes an operating member 107, a holder 108, a movable member 109, and the like.
[0009]
The actuating member 107 made of a synthetic resin molded product has a recess 107 a provided on both side surfaces and a projection 107 b projecting downward. The actuating member 107 has a front end portion at the base portion of the operating lever 103. In addition to being fixed, the protrusion 107b engages with the slider receiver 113, and the slider receiver 113 is moved in accordance with the movement of the operating member 107, so that the second switch S4 is operated. ing.
[0010]
The holder 108 made of a synthetic resin molded product has a pair of protruding pieces 108a extending forward from both side surfaces, and a protrusion 108b provided inside the protruding piece 108a, and between the pair of protruding pieces 108a, The operating member 107 is disposed, and the projection 108b is snap-fitted into the recess 107a, and the operating member 107 is attached to the holder 108 so as to be swingable in the vertical direction.
[0011]
The holder 108 has a mountain-shaped cam surface 108c provided at the tip, a pair of support shafts 108d and 108e provided on the upper and lower surfaces, and a protrusion 108f provided on the lower surface.
The holder 108 is pivotally attached to each of the support shafts 108d and 108e in the recesses (not shown) of the first and second cases 101 and 102, and the protrusion 108f slides. By engaging with the child receiver 112 (see FIG. 10), the slider receiver 112 is moved in accordance with the movement of the holder 108, and the first switch S3 is operated.
[0012]
The movable member 109 made of a synthetic resin molding has a leg portion 109a and a drive portion 109b. The movable member 109 is inserted into an opening 108g formed in the holder 108, and the leg portion 109a is inserted into the opening 108g. It is snap-fitted to the holder 108 and is swingably attached to the holder 108.
The driving portion 109b extends forward along the upper surface of the holder 8, and the receiving portion 109c provided on the driving portion 109b is inserted into the second opening 105c of the second lever member 105. It has become.
[0013]
As shown in FIG. 10, a first driving body 124 made of a synthetic resin molded product is slidably accommodated in the rear end portion of the holder 108, and the front end of the first driving body 124 is stored. The portion is pressed against the cam surface 110 of the first case 101 by the repulsive force of the spring 125 interposed between the first driving body 124 and the leg portion 109a of the movable member 109, and the movable member 109 The leg 109a is in pressure contact with the inner surface of the holder 108.
[0014]
As described above, the operating member 107 fixed to the operation lever 103 and the holder 108 are rotatably connected at the fitting portion between the concave portion 107a and the projection 108b, and the holder 108 is connected to the first and second cases. Reference numerals 101 and 102 denote fitting portions of the support shafts 108d and 108e, which are rotatably connected.
[0015]
Therefore, when the operation lever 103 is turned to the left or right turn instruction position, the operation lever 103, the operating member 107, and the holder 108 are in the direction of arrow A (FIG. 9) with the support shafts 108d and 108e as axes. However, when the operation lever 103 is rotated in the direction of the arrow B perpendicular to the indicated position, the operation lever 103 and the actuating member 107 have a straight line connecting both protrusions 108b with respect to the holder 108 as a rotation axis. Rotate by a predetermined angle in the vertical direction.
[0016]
As shown in FIG. 10, the second driving body 127 is slidably held at the rear end portion of the actuating member 107 via a spring 126, and the distal end portion of the second driving body 127 is The cam surface 108h formed inside the holder 108 is in pressure contact.
The sliding direction of the second driving body 127 moving on the cam surface 108h is orthogonal to the first driving body 124, and the operation lever 103 is rotated in the direction of arrow B (see FIG. 9). At this time, the actuating member 107 rotates so that the second driving body 127 slides on the cam surface 108h.
[0017]
Next, the operation of the conventional turn signal switch device will be described. When the operation lever 103 is in the neutral position, the first driver 124 is positioned in the valley of the central portion of the cam surface 110, and The cam portion 104c of the lever member 104 is in contact with the apex of the cam surface 108c of the holder 108, and the first lever member 104 moves forward against the biasing force of the torsion coil spring 106 as shown in FIG. ing.
Therefore, the contact portion 104d of the first lever member 104 is located outside the rotation locus of the cancel projection 128 that rotates in conjunction with the handle. Even if the handle is rotated in this state, the cancel projection 128 is The operation lever 103 is maintained in the neutral position without contacting the contact portion 104d of the first lever member 104.
[0018]
Next, when the operation lever 103 is rotated from this neutral position in either the direction of the arrow A1 or the direction of the arrow A2 in FIG. 11, the tip of the first driver 124 slides on the cam surface 110. Thus, a click feeling is generated when the lock portion 110b is engaged and the slope of the cam surface 110 is overcome.
[0019]
Here, for example, when the operation lever 103 is rotated in the direction of the arrow A2 in FIG. 11, the holder 108 and the movable member 109 are also rotated in the same direction in conjunction with the operation lever 103, and accordingly, the top of the cam surface 108c is camped. As shown in FIG. 13, the first lever member 104 retracts along the longitudinal direction of the first and second elongated holes 104a and 104b by receiving the elastic force of the arm portion of the torsion coil spring 106, as shown in FIG. (The rear side with respect to the operation lever 103), and the contact portion 104d advances into the rotation locus of the cancel projection 128.
[0020]
Further, as the operation lever 103 rotates in the arrow A2 direction, the receiving portion 109c of the movable member 109 held at the stable position of the holder 108 is displaced in the second opening 105c of the second lever member 105. As shown in FIG. 13, the receiving portion 109c comes into contact with one curved portion 105e of the second opening 105c.
Further, as the operation lever 103 rotates in the arrow A2 direction, the projection 108f of the holder 108 drives one of the slider receivers 112, so that the switch S3 is operated to switch the contacts. An unillustrated right turn lamp blinks.
[0021]
Further, when the handle is rotated in the direction of arrow C (reverse direction) in the right turn state shown in FIG. 13, the cancel projection 128 hits the contact portion 104 d of the first lever member 104 during the return operation.
As a result, the first lever member 104 rotates clockwise about a shaft portion (not shown), and accordingly, the second lever member 105 connected to the first lever member 104 is moved to the shaft. Therefore, the second opening 105c of the second lever member 105 is rotationally displaced upward in FIG.
[0022]
As a result, the curved portion 105e of the second opening 105c presses the receiving portion 109c of the movable member 109 upward, and this pressing force is transmitted to the holder 108 via the movable member 109, so that it is held by the holder 108. Further, the tip of the first driving body 124 moves away from the lock portion 110b of the cam surface 110 and moves to the central valley portion 110a, and the operation lever 103 and the first and second lever members 104 and 105 are It automatically returns to the neutral position shown in FIG.
[0023]
Further, in the right turn state shown in FIG. 13, when some force that prevents the automatic return is applied to the operation lever 103, for example, when the handle is rotated in the reverse direction while pressing the operation lever 103, Although the second lever member 105 tries to rotate clockwise around the shaft portion, the holder 108 does not rotate because the operation lever 103 is held down, and the second opening portion 105c and the receiving portion 109c are not rotated. An excessive load is generated at the contact portion.
[0024]
When such an overload occurs, as shown in FIG. 14, the receiving portion 109 c is pressed along the curved portion 105 e by the partial pressure in the rotational direction of the second lever member 105, and the movable member 109 is moved to the spring 125. The first and second lever members 104 and 105 are hindered by the receiving portion 109c because they swing from the stable position indicated by the two-dot chain line in FIG. 14 to the retracted position indicated by the solid line against the repulsive force. It can rotate without.
When the cancel protrusion 128 passes through the contact portion 104d of the first lever member 104, the movable member 109 automatically returns from the retracted position to the stable position by the repulsive force of the spring 125, and therefore the right turn state shown in FIG. Maintained.
[0025]
On the other hand, when the operation lever 103 is rotated in the direction orthogonal to the indicated position (the direction of arrow B in FIG. 9), the operation lever 103 and the actuating member 7 are protruded from the first and second cases 101 and 102 and the holder 108 by a protrusion 108b. Rotate by a predetermined angle in the vertical direction with the straight line connecting the two as a rotation axis, and the tip of the second drive body 127 slides on the cam surface 108h of the holder 108 and moves over the cam surface 8h. A feeling arises.
Then, as the operation lever 103 is rotated, the projection 107b of the operating member 107 drives the other slider receiver 113, so that the switch S4 is operated to switch the contacts, and the beam switching and A passing operation is performed.
[0026]
[Problems to be solved by the invention]
Since the conventional turn signal switch device has a configuration in which the cancel lever 104 and the lever member 105 are overlapped in a plane, the arrangement of the turn signal switch device becomes long, and there is a problem that the depth becomes large.
Further, in order to return the operation lever 103, the holder 108 and the movable member 109 are required, the number of parts is increased, the assemblability is deteriorated and the cost is increased, and the storage space for the movable member 109 is also required. There is a problem of becoming large.
[0027]
Accordingly, an object of the present invention is to provide an inexpensive turn signal switch device that is small in the depth direction and has good assemblability.
[0028]
[Means for Solving the Problems]
As a first means for solving the above problems, a housing having an upright wall provided with a first cam surface, an operating lever rotatably supported by the housing, and cooperation with the first cam surface A first driving body that holds the operation lever in a neutral position and an operating position, a first spring that biases the first driving body toward the first cam surface, and a cancel protrusion on the handle side.

However, the first lever member (cancel lever) 4 is provided. In addition, a receiving portion may be provided, and a cam portion may be provided on the holder 8.
[0053]
Next, the operation of the turn signal switch device according to the present invention will be described. When the operation lever 3 is in the neutral position, the first driver 24 is located in the valley 10a at the center of the cam surface 10, and The first lever member 4 is in contact with the cam portion 4c of the first lever member 4 at the apex of the receiving portion 8h of the holder 8, and the first lever member 4 is biased by the torsion coil spring 6 as shown in FIGS. It is moving in the forward direction against.
Therefore, the contact portion 4e of the first lever member 4 is located outside the rotation locus of the cancel projection 28 that rotates in conjunction with the handle. Even if the handle is rotated in this state, the cancel projection 28 is The operation lever 3 is maintained in the neutral position without contacting the contact portion 4e of the first lever member 4.
[0054]
Next, when the operation lever 3 is rotated from the neutral position shown in FIGS. 5 and 6 in either the direction of the arrow A1 or the direction of the arrow A2 in FIG. When the user slides on the surface 10 and is locked by the lock portion 10b, the user feels a click when getting over the slope of the cam surface 10.
[0055]
Here, for example, when the operation lever 3 is rotated in the direction of the arrow A2 in FIG. 3, the holder 8 is also rotated in the same direction in conjunction with the operation lever 3, and accordingly, the top of the receiving portion 8h is detached from the cam portion 4c. Therefore, as shown in FIGS. 7 and 8, the first lever member 4 receives the elastic force of the arm portion 6c of the torsion coil spring 6 and the longitudinal direction (formation direction) of the first and second elongated holes 4a and 4b. The contact portion 4e advances into the rotation locus of the cancel projection 28.
[0056]
Further, as the operating lever 3 rotates in the direction of arrow A2, the arm portion 8j of the holder 8 drives one of the slider receivers 12, so that the operation of the first switch S1 is performed and the switching of the contacts is performed. A right turn lamp (not shown) blinks.
Further, at this time, the protrusion 8 f of the holder 8 is in a state of being close to the second engagement portion 5 e of the first lever member 5.
[0057]
7 and 8, when the handle is rotated in the direction of arrow C (reverse direction), the cancel protrusion 28 is brought into contact with the contact portion 4e of the first lever member 4 during the return operation. bump into.
As a result, the first lever member 4 rotates clockwise around the protrusion 2g of the upright wall 2e, and accordingly, the second lever member 5 engaged with the first lever member 4 has the shaft portion. Since the second lever member 5 rotates in the clockwise direction around 2f, the second engaging portion 5e of the second lever member 5 engages with the protruding portion 8f of the holder 8 to rotate the holder 8.
[0058]
As a result, the distal end portion of the first driving body 24 held by the holder 8 is detached from the lock portion 10b of the cam surface 10 and moves to the central valley portion 10a, and the operation lever 3 and the second lever member 5 are moved. Automatically returns to the neutral position shown in FIGS.
Further, when the holder 8 returns to the neutral position, the receiving portion 8h is engaged with the cam portion 4c of the first lever member 4, and the first lever member 4 is pushed back against the torsion coil spring 6 in the forward direction. Similarly, the first lever member 4 automatically returns to the neutral position shown in FIGS.
[0059]
In the right turn state shown in FIGS. 7 and 8, when some force that prevents the automatic return is applied to the operation lever 3, for example, when the handle is rotated in the reverse direction while pressing the operation lever 3, the first The lever member (cancellation lever) 4 is pressed by the cancel protrusion 28 and rotates about the protrusion 2g until the second engaging portion 5e hits the protrusion 8f. After the rotation, the first lever The member 4 slides forward (in the direction of the operation lever 3) using the protrusion 2g and the first engaging portion 5d as a guide, and retreats outside the rotation locus of the cancel protrusion 28.
[0060]
For this reason, the handle can be operated while maintaining a right-turned state without generating an excessive load between the first lever member 4 and the holder 8.
When the cancel protrusion 28 passes through the contact portion 4e of the first lever member 4, the first lever member 4 automatically returns from the retracted position to a position within the rotation locus of the cancel protrusion 28 by the repulsive force of the spring 25. To return to a cancelable state.
[0061]
On the other hand, when the operation lever 3 is rotated in the direction orthogonal to the indicated position (the direction of arrow B in FIG. 2), the operation lever 3 and the actuating member 7 are protruded from the first and second cases 1 and 2 and the holder 8 by a protrusion 8b. Rotate by a predetermined angle in the vertical direction with the straight line connecting the two as a rotation axis, and the tip of the second drive body 27 slides on the cam surface 8e of the holder 8 and moves over the cam surface 8e. A feeling arises.
As the operation lever 3 is rotated, the arm portion 7b of the operating member 7 drives the other slider receiver 13, so that the second switch S2 is operated to switch the contact. Beam switching and passing operations are performed.
[0062]
