摘要： A driving device is equipped with a vibration actuator. The vibration actuator includes a roller element, an elastic member and electro-mechanical converting elements, which contact the elastic member. The electro-mechanical converting elements generate a vibration to drive the elastic member. Additionally, the roller element transfers relative movement to at least one element to be moved by contacting a driving part of the vibration actuator and by rotating. The roller element comprising a first part contacting the at least one driving section of the elastic member and a second part, separate from the first part, contacting the at least one element. In operation, the at least one electro-mechanical converting element vibrates the at least one driving section of the elastic member. The at least one driving section transfers the vibration to the first part of the roller element to rotate the roller element and the least one element is moved by rotation of the second part of the roller element.
