Description
Claims (3)
- 回転軸と共に回転し、ディスクの内周面が挿入されるケースと、
一端部側は前記ケースの側板の外側に位置して前記ディスクの内周面と接触し、他端部側は前記ケースの側板の内側に位置し、回転および直線運動可能に設けられ、前記ディスクが前記ケースから離脱することを防止する複数のアームと、
前記アームを前記ケースの側板の外側に弾性支持する弾性部材とを備え、
前記ディスクが前記ケースに挿入されるとき、前記ディスクが前記アームの一端部側を押圧することにより、前記アームの他端部側が接触する前記ケースの上板部位は、前記ケースの内側にいくほど上板の厚さが次第に薄くなる形態の傾斜面として形成され、前記傾斜面の開始部位は、ラウンディングされているスピンドルモータのディスクのクランピング装置。 - 前記傾斜面は、平面であることを特徴とする請求項1に記載のスピンドルモータのディスクのクランピング装置。
- 前記傾斜面は、曲面であることを特徴とする請求項1に記載のスピンドルモータのディスクのクランピング装置。
