【０００１】
【発明の属する技術分野】
本発明は、例えば自動車用電気接続箱のようなケースの電線貫通部に設けて該電線貫通部をシールするグロメットに関するものである。
【０００２】
【従来の技術】
従来のこの種のグロメットでは、その差込み取付け部を取付け相手である電気接続箱の如きケースの取付け部の溝に、外すことを考えないで差込んで取付けていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、このような従来のグロメットの取付け構造では、メンテナンスの際に該グロメットをケースの取付け部から外す際には、外し治具を用いないと外すことができず、特に自動車のエンジンルームのように多数の部品が搭載される場所に配置された場合、手さぐりの状態で外さなければならないことがあり、外し治具を用いての作業は非常に困難であるという問題点があった。
【０００４】
本発明の目的は、取付け相手からの外し作業を外し治具を用いないで行えるグロメット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、電線を貫通させる電線嵌合筒部（２）と、ロアーケース部（３ａ）とアッパーケース部（３ｂ）とからなる半割構造のケースの前記ロアーケース部に設けられたロアーケース側取付部（４ａ）に形成された第１及び第２のロアーケース側差し込み溝（５ａ）及び（６ａ）と前記アッパーケース部（３ｂ）に設けられたアッパーケース側取付部（４ｂ）に形成された第１及び第２のアッパーケース側差し込み溝（５ｂ）及び（６ｂ）とに差し込んで取り付けられる差込み取付け部（７）とを備え、前記差込み取付部（７）は、貫通孔（１１）を有する筒部（１２）と、該筒部の一端に形成されて前記第１のロアーケース側差込み溝（５ａ）及び第１のアッパーケース側差込み溝（５ｂ）に差し込まれる電線嵌合筒部取付けフランジ部（１３）と、前記筒部の他端に形成されて前記第２のロアーケース側差込み溝（６ａ）及び第２のアッパーケース側差込み溝（６ｂ）に差し込まれる差込みフランジ部（１４）とを有して、前記差込み取付部（７）の電線嵌合筒部取付けフランジ部（１３）に前記電線嵌合筒部（２）の基部が取り付けられるグロメットを改良するものである。
【０００６】
本発明に係わるグロメットにおいては、電線嵌合取付けフランジ部（１３）と差込みフランジ部（１４）との間の筒部（１２）の左右両側に、差込みフランジ部側（１４）に隣接させて一対のロック操作アーム（１５，１５）が片持ちで支持されて、該一対のロック操作アーム（１５，１５）にそれぞれロック突起（１６，１６）が設けられている。またロアーケース側取付部（４ａ）には一対のロック操作アームにそれぞれ設けられたロック突起（１６，１６）を嵌めるためのロック凹部（９，９）が設けられていて、差込み取付部（７）の電線嵌合筒部取付けフランジ部（１３）及び差込みフランジ部（１４）をそれぞれ第１のロアーケース側差込み溝（５ａ）及び第２のロアーケース側差込み溝（６ａ）に差し込んだ際にロック突起（１６，１６）がロック凹部（９，９）に嵌り込んでロアーケース側取付部（４ａ）にロックされた状態になり、一対のロック操作アーム（１５，１５）を互いに接近させる方向に撓ませた際にロック突起（１６，１６）がロック凹部（９，９）から抜けてロアーケース側取付部（４ａ）から外すことができるように構成されている。
【０００７】
このようなグロメットは、取付け相手の取付け部に差込み取付け部を差込むと、ロック突起が取付け相手のロック凹部に嵌まり込んでロック状態となり、外れなくなる。
【０００８】
メンテナンスの際に、該グロメットを取付け相手の取付け部から外す際には、単にロック突起が取付け相手のロック凹部から抜ける方向にロック操作アームを操作すればよく、外し治具を用いないで片手操作でも簡単に取り外すことができ、しかも手さぐりの状態でも外し操作を容易に行うことができる。
【０００９】
【発明の実施の形態】
図１〜図３（Ａ）〜（Ｃ）は本発明に係るグロメットにおける実施の形態の第１例を示すもので、図１は本例のグロメットと取付け相手との関係を示す組立て前の斜視図、図２は本例のグロメットの差込み取付け部を示す斜視図、図３（Ａ）は本例のグロメットのケースへの取付け状態を示す正面図、図３（Ｂ）は図３（Ａ）でアッパーケース部を外した状態での平面図、図３（Ｃ）は図３（Ａ）のＸ−Ｘ線断面図、図３（Ｄ）は図３（Ａ）のＹ−Ｙ線断面図である。
【００１０】
このグロメット１は、ワイヤーハーネス等の電線を液密に貫通させるゴム等よりなる電線嵌合筒部２と、該電線嵌合筒部２の基部に設けられて取付け相手のケース３の半割り構造のロアーケース部３ａにおける半割り構造の取付け部４ａに設けられているＵ字状差込み溝５ａ，６ａと半割り構造のアッパーケース部３ｂにおける半割り構造の取付け部４ｂに設けられている逆Ｕ字状差込み溝５ｂ，６ｂとに差込んで取付けるためのプラスチック等よりなる差込み取付け部７とからなる点は、従来と同様である。
【００１１】
即ち、ケース３は、ロアーケース部３ａとアッパーケース部３ｂとの半割り構造になっている。これらロアーケース部３ａ及びアッパーケース部３ｂにはそれぞれ、ワイヤーハーネス等の電線を引込む箇所に貫通孔８を包囲して半割り構造のロアーケース側取付け部４ａ及びアッパーケース側取付部４ｂが一体に設けられている。半割構造のロアーケース側取付け部４ａには、その内周に沿い、上方に開口してＵ字状の第１及び第２のロアーケース側差込み溝５ａ及び６ａが設けられている。半割構造のアッパーケース部側取付け部４ｂには、その内周に沿い、下方に開口して逆Ｕ字状の第１及び第２のアッパーケース側差込み溝５ｂ，６ｂが設けられている。

【００１３】
差込み取付け部７は、貫通孔１１を有する筒部１２と、筒部１２の一端に設けられて第１のロアーケース側差込み溝５ａ及び第１のアッパーケース側差込み溝５ｂに差込まれる電線嵌合筒部取付けフランジ部１３と、筒部１２の他端に設けられて第２のロアーケース側差込み溝６ａ及び第２のアッパーケース側差込み溝６ｂに差し込まれる差込みフランジ部１４とで構成されている。電線嵌合筒部取付けフランジ部１３には、ゴム製の電線嵌合筒部２がその基部２ａを被せることにより取付けられている。
【００１４】
電線嵌合筒部取付けフランジ部１３と差込みフランジ部１４との間の筒部１２の左右には、差込みフランジ部１４側に隣接させてロック操作アーム１５がその下端を該筒部１２に片持ち支持させて縦向きにそれぞれ設けられている。これら左右のロック操作アーム１５は上端がフリーになっていて、互いに上端を接近させる方向に撓ませることができるようになっている。これら左右のロック操作アーム１５には、ケース３の取付け部４ａの左右における各ロック凹部９に嵌めてロックさせるロック突起１６がそれぞれ設けられている。
【００１５】
このようなグロメット１は、ロアーケース側取付け部４ａに差込み取付け部７を差込むと、ロック突起１６が取付け相手の取付け部４ａにおける各ロック凹部９に嵌まり込んでロック係止部１０に引っ掛かり、ロック状態となって外れなくなる。
【００１６】
このようにしてのグロメット１の取付けの後、ロアーケース部３ａの上にアッパーケース部３ｂを被せ、このアッパーケース部３ｂの取付け部４ｂを差込み取付け部７の上に被せる。
【００１７】
メンテナンスの際に、該グロメット１をロアーケース側取付け部４ａから外す際には、アッパーケース部３ｂを除去した状態で、単にロック突起１６が取付け部４ａのロック凹部９から抜ける方向にロック操作アーム１５を撓ませるように操作すればよく、外し治具を用いないで片手操作でも簡単に取り外すことができる。特に、本例のようにロック操作アーム１５が筒部１２の左右に存在する場合には、片手の親指と他の指とで左右のロック操作アーム１５の先端を摘んで相互に接近させる方向に左右のロック操作アーム１５を撓ませると、各ロック突起１６が取付け部４ａの各ロック凹部９から抜け、この状態で左右のロック操作アーム１５を摘み上げると、簡単に差込み取付け部７が取付け部４ａから抜けて、グロメット１を外すことができる。
【００１８】
【発明の効果】
本発明に係るグロメットにおいては、差込み取付け部に片持ち支持でロック操作アームを設け、該ロック操作アームには取付け相手の取付け部にロックさせるロック突起を設けているので、差込み取付け部を取付け相手の取付け部に差込むと、ロック突起が取付け相手のロック凹部に嵌まり込んでロック状態となり、外れなくなる。このため、メンテナンスのために該グロメットを取付け相手の取付け部から外す際には、単にロック突起が取付け相手のロック凹部から抜ける方向にロック操作アームを操作すればよく、外し治具を用いないで片手操作でも簡単に取り外すことができ、しかも手さぐりの状態でも外し操作を容易に行うことができる。
