Claims (3)
- ポンプ内において流体を移送するロータと、該ロータを回転させる金属製のシャフトと、ポンプボディ外部に位置すると共に前記シャフトに回転を伝達する合成樹脂製の駆動ギヤとからなり、前記駆動ギヤの成形と共に前記シャフトが鋳込み成形され、前記駆動ギヤに対して前記シャフトが貫通する接触領域内に、中空管とした軸方向に沿って連続する割り部が形成されたピン部材と前記シャフトに形成された貫通孔とからなり、前記ピン部材には、溶融した樹脂が流入する樹脂受けが管内に形成され、前記貫通孔に前記ピン部材が嵌入され、その長手方向両端が前記シャフトの外周表面から突出して形成されてなることを特徴とするポンプの駆動ギヤ装置。
- 請求項1において、前記ピン部材の長手方向両端が外周表面から突出した前記シャフトの周囲には、多数の小突起からなる粗面領域としたことを特徴とするポンプの駆動ギヤ装置。
- 請求項2において、前記粗面領域は、ローレット状部として形成されてなることを特徴とするポンプの駆動ギヤ装置。
