- 前記第二貫通溝は、前記歯の先端部を中心とすることを特徴とする、請求項1に記載のバックラッシュ補正作動部材。
- 前記各弾性曲げ部は、前記歯付きホイールプレートの半径方向内側に延伸し、前記歯付きホイールプレートのハウジング内で間隙を持って配置される部分を有することを特徴とする、請求項1に記載のバックラッシュ補正作動部材。
- 前記歯付きホイールプレートの厚さは0.1mm〜0.5mmであることを特徴とする、請求項1に記載のバックラッシュ補正作動部材。
- 前記歯付きホイールプレートの前記歯の高さは0.15mm〜0.6mmであることを特徴とする、請求項1に記載のバックラッシュ補正作動部材。
- 前記歯付きホイールプレートの前記歯の、前記作動部のピッチ円直線沿いに測定される厚みは0.05mm〜0.3mmであることを特徴とする、請求項1に記載のバックラッシュ補正作動部材。
- 前記歯付きホイールプレートは電鋳法により得られたことを特徴とする、請求項1に記載のバックラッシュ補正作動部材。
- 前記歯付きホイールプレートはNi、NiP、NiCoからなる群から選択される材料からなることを特徴とする、請求項9記載のバックラッシュ補正作動部材。
- 前記歯付きホイールプレートはプラズマドライエッチング法により得られたことを特徴とする、請求項1に記載のバックラッシュ補正作動部材。
- 前記歯付きホイールプレートはシリコン素材からなることを特徴とする、請求項11記載のバックラッシュ補正作動部材。
- 前記歯付きホイールプレートは化学機械加工法またはエッチング法により得られたことを特徴とする、請求項1に記載のバックラッシュ補正作動部材。
- 前記歯付きホイールプレートは放電加工法により得られたことを特徴とする、請求項1に記載のバックラッシュ補正作動部材。
- 前記歯付きホイールプレートはレーザ切断法により得られたことを特徴とする、請求項1に記載のバックラッシュ補正作動部材。
