又、ロッド２の先端縁部に滑り傾斜面12を形成している。
【０００７】
本実施例における押圧部材10a にあっては、図１に示す様に、下向き円弧状の板材10b の両端部を収容部位 6a 内の奥部に一体化すると共に、板材 10b の中央部と収容部位 6a 内の奥部を連結部材 10c を介して一体化した圧縮弾性体であるが、かかる形態に限定せず、例えば、図示しないが、収容部位6a内の奥部に設けた屈曲板状の圧縮弾性体であったり、支承部材3aとは別体の、例えば圧縮バネの様な圧縮弾性体であったり、或いはロッド挿入部６の奥部に一体突設した単なる突部であっても良い。又、押圧部材10a の当接面11は、ロッド２の先端側に設けた段部におけるロッド挿入部６の奥側に向いた面としても良い。
【０００８】
図２に示す様に、ロッド２におけるロッド挿入部６の嵌挿部位6b内の部分の側部に突部13を形成すると共に、ロッド挿入部６における嵌挿部位6bの内周面に突部13の嵌合溝１を形成しても良い。又、突部13は、図１、２に示す様に、ロッド２の中間部を圧潰することで両側方に膨出した部分としている。
【０００９】
図１に示す様に、ロッド挿入部６の内周面に、ロッド２におけるロッド挿入部６内の部分の、係止凹部８とは反対側の部位が密着する様に、支承部材3aにロッド挿入部６を形成するのが望ましい。
【００１０】
図３、４に示す開閉体用サポート１の他の実施例にあっては、図１、２に示す開閉体用サポート１と同様のロッド２と、差込み部４及び受座部５を有する合成樹脂部品３である支承部材3aとにより構成され、支承部材3aにおける収容部位6a内に係止片７を、ロッド２の先端側面に、係止片７の先端の係止凹部８を形成しているが、係止凹部８における当接面９を誘導傾斜面とし、収容部位6a内の奥部の位置規制部10を、押圧部材10a ではなく、凸曲面を有する単なる凸部10d とし、ロッド２の先端側面における係止凹部８とは反対側に平坦面15を形成すると共に、支承部材3aにおけるロッド挿入部６に、上記平坦面15に密接する平坦面16を形成している。又、ロッド２の平坦面15は、図４に示す様に、ロッド２の先端部を圧潰することで形成すると共に、かかる圧潰によりロッド２の両側方に膨出した部分を、上記突部13の延長線上に形成している。又、ロッド２の先端縁部に面取り17を形成している。又、ロッド２の先端面を収容部位6aの奥部の位置規制部10、即ち凸部10d に対し当接又は近接状態となる様にしている。

【００１２】
次に、ロッド２の先端にへの合成樹脂部品３の装着過程を詳細に説明する。
合成樹脂部品３のロッド挿入部６にロッド２の先端を差し込む過程において、先ず最初にロッド２の先端の滑り傾斜面12が係止片７に当接し該係止片７を倒す。次に、ロッド２が、その外周面に係止片７の先端が摺接状態のまま進行し、ロッド２の先端側の当接面11、即ちロッド２の先端面が押圧部材10a に当接し該押圧部材10a を変形させる。次に、係止片７の先端が係止凹部８に位置してロッド２の周面から外れると、係止片７が弾性復元力により初期位置に復帰し、係止片７の先端が係止凹部８内に嵌まり込む。最終的に、押圧部材10a の弾性復元力によりロッド２を押し下げて、係止片７の先端を係止凹部８の当接面９に当接させて、ロッド２の先端に合成樹脂部品３を装着、固定する。
又、ロッド２の先端の滑り傾斜面12が係止片７に当接することで、合成樹脂部品３の装着時に係止片７の削れを防止する様にしている。
【００１３】
合成樹脂部品３のロッド挿入部６へのロッド２の差込過程で、ロッド２の先端が係止片７に当接した後、係止片７が若干変形すると共に、合成樹脂部品３の側部が外側へ膨らむ様に弾性変形して、ロッド２の外周面に係止片７の先端が摺接状態になり、次にロッド２の先端がロッド挿入部６の奥部の押圧部材10a に当接して押圧部材10a が変形すると共に、合成樹脂部品３の先端部が外へ膨らむ様に弾性変形し、そしてロッド２に装着後の合成樹脂部品３に極僅かな変形が残り、その弾性復元力が係止片７及び押圧部材10a を介してロッド２に作用して、ロッド２及び合成樹脂部品３が更に強固に一体化している。
【００１４】
図３、４に示す他の実施例にあっては、先ず最初にロッド２の先端の面取り17が係止片７に当接し該係止片７を倒す。次に、ロッド２が、その外周面に係止片７の先端が摺接状態のまま進行し、係止片７の先端が係止凹部８に位置してロッド２の周面から外れると、係止片７が弾性復元力により初期位置に復帰しようとして、当接面９に係止片７の先端が摺接状態のままロッド２が進行し、最終的に係止片７の先端が係止凹部８内に嵌まり込んで、ロッド２先端が位置規制部10、即ち凸部10d に対し当接又は近接状態となって、ロッド２の先端に合成樹脂部品３を装着、固定する。
【００１５】
合成樹脂部品３のロッド挿入部６へのロッド２の差込過程で、ロッド２の先端が係止片７に当接した後、係止片７が若干変形すると共に、合成樹脂部品３の側部が外側へ膨らむ様に弾性変形して、ロッド２の外周面に係止片７の先端が摺接状態になり、そしてロッド２に装着後の合成樹脂部品３に極僅かな変形が残り、その弾性復元力が係止片７及び平坦面16を介してロッド２に作用して、ロッド２及び合成樹脂部品３が更に強固に一体化している。
【００１６】
次に本発明に係るロッドと合成樹脂部品の取付構造の作用について説明する。
第１の実施例においては、押圧部材10a 及び／又は合成樹脂部品３の先端部の弾性復元力によりロッド２を下方へ押し下げ、第２の実施例においては、凸部10d に対しロッド２の先端が当接又は近接状態であることにより、合成樹脂部品３のロッド２に対する上方微動を防止又は極微量に抑止し、且つ係止片７の先端がロッド２の係止凹部８に対し係合状態になって当接面９に当接するため、ロッド２に対する合成樹脂部品３の上下微動を完全に防止するか、極めて微量に抑止される。
【００１７】
第１の実施例における係止片７及び押圧部材10a 、並びに第２の実施例における係止片７は、例えば、開閉体用サポートにより開閉体Ａを開放支持する場合の様に、合成樹脂部品３に上方より荷重が作用した場合に簡単に変形しない様に形成されることから、ある程度の強度が必要になるため、差込み部４を、ロッド挿入部６の奥側、即ち収容部位6aを差込み部４の両側方で開放することで枠状に形成すれば、差込み部４の変形が容易になり、第１の実施例における係止片７及び押圧部材10a 、並びに第２の実施例における係止片７をあまり変形させずに、ロッド２に合成樹脂部品３を装着可能になる。
【００１８】
【発明の効果】
要するに本発明は、ロッド挿入部６の入口側をロッド２の嵌挿部位 6b とすると共に、奥側を嵌挿部位 6b より広くしたロッド２の先端部の収容部位 6a とし、収容部位 6a の内に、該収容部位 6a の奥側へ斜めに突出する係止片７を設け、他方、ロッド２の先端側面に上記係止片７の先端の係止凹部８を形成したので、係止片７の先端及び係止凹部８の係合構造によりロッド２に対する合成樹脂部品３の抜脱を防止することが出来る。又、収容部位 6a の奥部に、ロッド２の先端が当接する、ロッド２の先端の位置規制部 10 を設けたので、位置規制部10によりロッド２の先端を位置決めしているため、装着状態における合成樹脂部品３の上下微動を防止又は極めて微量に抑止出来る。
而も、押圧部材10a がロッド２の先端面に、係止片７の先端が係止凹部８の上部に夫々当接状態となるため、ロッド２に対する合成樹脂部品３の組付け向きを維持することが出来る。
よって、ロッド２及び合成樹脂部品３の一体性に優れた製品にすることが出来る。
【００１９】
位置規制部10を、収容部位 6a 内の奥部に設けた押圧部材 10a とし、該押圧部材 10a を、下向き円弧状の板材 10b の両端部を収容部位 6a 内の奥部に一体化すると共に、板材 10b の中央部と収容部位 6a 内の奥部を連結部材 10c を介して一体化した圧縮弾性体としたので、かかる押圧部材10a は弾性変形可能であり、ロッド２の先端を押圧部材10a との当接位置より更に奥に差し込むことが出来るため、合成樹脂部品３を大きく変形させずに係止片７の先端及び係止凹部８を係合させることが出来、而も押圧部材10a とロッド２の先端面及び係止片７と係止凹部８の当接部位の密着度が押圧部材10a の弾性復元力により大きくなるため、ロッド２に対する合成樹脂部品３の一体性を更に向上させることが出来る。
【００２０】
合成樹脂部品３の上方部位を、ロッド挿入部６における収容部位 6a の両側方で開放することで枠状に形成したので、かかる差込み部４を変形容易に成形することが出来るため、ロッド２への合成樹脂部品３の装着作業の容易化を図ることが出来る。
【００２１】
ロッド２の先端側面に突部13を設けると共に、合成樹脂部品３におけるロッド挿入部６の入口側部位の内側面に突部13の嵌合溝14を刻設したり、或いはロッド２の先端側面における係止凹部８とは反対側に平坦面15を形成すると共に、合成樹脂部品３におけるロッド挿入部６に、上記平坦面15に密接する平坦面16を形成したので、ロッド２に対する合成樹脂部品３の回転微動を防止することが出来るため、ロッド２及び合成樹脂部品３の一体性を更に向上させることか出来る等その実用的効果甚だ大である。
