【０００１】
【発明の属する技術分野】
本発明は、特に、モータ等の回転駆動部材の軸部材に取り付けて好適なツマミの取付構造に関する。
【０００２】
【従来の技術】
従来のツマミの取付構造の図面を説明すると、図３は、従来のツマミの取付構造を示す分解斜視図である。
【０００３】
電動のモータから成る回転駆動部材５１は、略円筒状の本体部５１ａと、本体部１ａの先端部から外方に突出して配設された回転軸などの円柱状の軸部材５１ｂとを有している。この軸部材５１ｂは、本体部５１ａに図示していない端子から通電することによって、所定の回転をし、また、本体部５１ａへの非通電時にも軸部材５１ｂは、時計方向、又は、反時計方向に容易に回転をすることができるように構成されている。
【０００４】
合成樹脂材料から成り、成形加工によって形成された取付部材５２は、基部５３と、基部５３の中心から同一円周上に設けられた円環状の第１の取付部５４と、第１の取付部５４と同心円上で、第１の取付部５４より径寸法が大きい第２の取付部５５とを有している。また、前記第１の取付部５４と第２の取付部５５とは、基部５３の中心軸から外方に突出された鍔状に形成されている。
【０００５】
また、前記基部５３は、略平坦面であるように形成された前面壁５３ａと、該前面壁５３ａの周囲から後方に延びる筒状の側壁部５３ｂとを有している。また、前記円環状の第１の取付部５４と第２の取付部５５とは、筒状の側壁部５３ｂの後端から外方に突出して配設されている。
【０００６】
また、前記基部５３の前記前面壁５３ａは、前記前面壁５３ａの中心に位置する円形の貫通孔５３ｃとを有している。
また、金属材料から成り、インサート成形加工によって一体化された円筒部材５３ｄが、貫通孔５３ｃ内に配設されている。
【０００７】
前記円筒部材５３ｄ内には、回転駆動部材５１の軸部材５１ｂが挿入され、例えば、ネジ（図示せず）止めなどの適宜手段にて、前記円筒部材５３ｄが軸部材５１ｂに取り付けられ、この取り付けによって、取付部材５２が軸部材５１ｂと一体化された状態となり、取付部材５２が軸部材５１ｂと共に回転可能となっている。
【０００８】
合成樹脂材料から成り、成形加工によって形成されたツマミ５６は、円板形の前面壁５６ａと、前面壁５６ａの周囲から後方に延びる筒状の側壁５６ｂと、筒状の側壁５６ｂ内で内方に突出し、同一円周上に位置する複数個（例えば、４個）の掛け止め部５７と、筒状の側壁５６ｂ内で内方に突出し、同一円周上に位置する複数個（例えば、４個）の押さえ部５８とを有している。また、掛け止め部５７と押さえ部５８とは同一円周上に位置している。
【０００９】
このツマミ５６は、前記取付部材５２上を同心的に覆うように取付部材５２の前面に配設された状態で、ツマミ５６の各掛け止め部５７が、円環状の第１の取付部５４に掛け止めされ、且つ、各押さえ部５８が、第２の取付部５５上に当接されて、ツマミ５６と取付部材５２とが結合されている。
そして、この結合によって、取付部材５２の側壁部５３ｂがツマミ５６の側壁５６ｂ内に位置するように配置されている。
【００１０】
次に、上述の従来のツマミの取付構造に係わる組立について説明する。
先ず、回転駆動部材５１の軸部材５１ｂには、取付部材５２と一体化された円筒部材５３ｄを取り付ける。
【００１１】
次に、取付部材５２の前面壁５３ａ上には、ツマミ５６の前面壁５６ａが被さるように対向して配設し、取付部材５２の側壁部５３ｂがツマミ５６の側壁５６ｂ内に位置するように配設されている。
この状態から、ツマミ５６を軸部材５１ｂの軸線方向に押圧すると、掛け止め部５７が第１の取付部５４の頂部を乗り越えて、第１の取付部５４に掛け止めされ、且つ、押さえ部５８が第２の取付部５５上に当接されて配設される。
【００１２】
この掛け止め部５７の第１の取付部５４への掛け止めと、押さえ部５８の第２の取付部５５上への当接によって、ツマミ５６が取付部材５２上に取り付けられる。
【００１３】
【発明が解決しようとする課題】
しかしながら、上述のツマミの取付構造では、ツマミ５６を取付部材５２に押し込んで取り付けする際に、ツマミ５６が取付部材５２に対して傾斜した状態で押し込まれると、取付部材５２が回転し易い軸部材５１ｂに取り付けられていることから、取付部材５２が容易に回転して、取付部材５２がぐらつき、ツマミ５６が取り付け辛く、且つ、ツマミ５６のそれぞれの掛け止めが同時にできず、取り付け難いという問題がある。
また、ツマミ５６が取付部材５２に掛け止めされているのみの状態で取り付けされ、このことから、ツマミ５６が取付部材５２に対して空転するという問題がある。
【００１４】
本発明のツマミの取付構造は、上述の問題点を解決し、その目的は、ツマミの取付部材への取り付けが容易であるツマミの取付構造を提供することにある。
