Abstract
A vibration actuator for use with a relative moving element includes a plate shaped elastic member. An electro-mechanical conversion element is attached to an upper surface of the elastic member. The electro-mechanical conversion element generates longitudinal and bending vibrations in the elastic member such that a side surface of the elastic member constitutes a neutral surface of the vibrations. A driving force output member is disposed at a bottom surface of the elastic member, and contacts the relative moving element. An extension member is disposed at the side surface of the extension member. A pressing force is applied by the extension member to the driving force output member to press the driving force output member toward the relative moving element.
