Description
例えば,駆動摩擦部材12の断面形状は必ずしも円形に限らない。圧電素子11の端面の全体が駆動摩擦部材12の端面に接している形状であればよい。例えば,駆動摩擦部材12の外周の一部が弦状に切り取られた形状等でも良い。また,圧電素子11の断面形状も円や正方形に限らない。
また例えば,駆動摩擦部材12は,必ずしも軸方向に均一の形状でなくても良い。例えば,接合面21の近傍のみが太く,その他の部分は細く形成された駆動摩擦部材12であっても良い。
また例えば,上記の形態の駆動装置1で,固定部材13,軸受け14,15の形状は1つの例であり,これに限らない。
また例えば,上記の形態では,圧電素子11を使用した駆動装置1を示しているが,電歪素子,磁歪素子等の他の電気機械変換素子についても同様に適用可能である。

12 駆動摩擦部材
13 固定部材
Claims (2)
- 固定部材と,前記固定部材に一端が固定された電気機械変換素子と,前記電気機械変換素子の他端に一端が接着接合されるとともに,軸受け部に摺動可能に支持された駆動摩擦部材とを有し,前記駆動摩擦部材に摺動可能に保持された移動体を,前記電気機械変換素子の急速な変位と緩やかな変位との組合せによる伸縮により移動させる電気機械変換素子を用いた駆動装置において,
前記電気機械変換素子の前記駆動摩擦部材に対する接合面が,前記駆動摩擦部材の前記電気機械変換素子に対する接合面に包含されており,
前記駆動摩擦部材は,前記電気機械変換素子との前記接合面の位置まで移動体が摺動可能な形状であり,
前記駆動摩擦部材は,前記電気機械変換素子との前記接合面が,前記電気機械変換素子の伸長時には,前記電気機械変換素子の短縮時よりも前記固定部材から離隔し,かつ前記軸受け部に入り込んで位置するように配置されていることを特徴とする電気機械変換素子を用いた駆動装置。 - 請求項1に記載の電気機械変換素子を用いた駆動装置において,
前記駆動摩擦部材は,外周の少なくとも一部が円弧である断面形状を有し,
前記電気機械変換素子のうち少なくとも前記駆動摩擦部材に対する接合面を含む部分が,前記駆動摩擦部材の断面形状の円弧を外接円とする多角形の断面形状を有することを特徴とする電気機械変換素子を用いた駆動装置。
