Claims (5)

被駆動部材を所定方向に平行移動させるアクチュエータであって、
信号が印加されることによって振動を励起する振動励起素子を備え、この振動励起素子が励起した振動によって前記被駆動部材に対して力を印加することが可能な振動体と、
前記振動体を回転可能に保持し、前記振動体の振動軌跡と前記被駆動部材の移動方向とのなす角を変更する回転手段とを有することを特徴とするアクチュエータ。An actuator that translates a driven member in a predetermined direction,
A vibration body that includes a vibration excitation element that excites vibration when a signal is applied, and that can apply force to the driven member by vibration excited by the vibration excitation element;
An actuator comprising : a rotating unit that rotatably holds the vibrating body, and changes an angle formed by a vibration locus of the vibrating body and a moving direction of the driven member . 前記振動体が、前記回転手段に対してこの回転軸とは異なる位置に設けられていることを特徴とする請求項１に記載のアクチュエータ。  The actuator according to claim 1, wherein the vibrating body is provided at a position different from the rotation axis with respect to the rotating means. 前記回転手段は、前記振動体を回転させて前記振動体の振動軌跡と前記被駆動部材の移動方向とのなす角を変更することで、前記所定方向における前記被駆動部材の駆動力を変化させることを特徴とする請求項１又は２に記載のアクチュエータ。The rotating means changes the driving force of the driven member in the predetermined direction by changing the angle formed by the vibration locus of the vibrating body and the moving direction of the driven member by rotating the vibrating body . The actuator according to claim 1 or 2, wherein 前記回転手段は、前記振動体による前記被駆動部材の所定方向への駆動を維持する範囲内で回転可能であることを特徴とする請求項１から３のいずれか１つに記載のアクチュエータ。It said rotation means, actuator according to any one of claims 1 to 3, characterized in that the rotatable within a range that maintains the drive in a predetermined direction of the driven member by the vibrator. 請求項１から４のいずれか１つに記載のアクチュエータと、
このアクチュエータにより駆動され、所定方向に平行移動可能な被駆動部材とを有することを特徴とする駆動装置。An actuator according to claims 1 any one of 4,
And a driven member that is driven by the actuator and is movable in a predetermined direction.
