Abstract
A vibration wave driving apparatus includes a vibration actuator; and a driven member configured to be driven by the vibration actuator. The vibration actuator includes a vibrator having an electric-mechanical energy conversion element and an elastic member to which the electric-mechanical energy conversion element is fixed; a pressurizing member configured to pressurize the vibrator; a contacting member configured to pressurizing-contact with the vibrator by pressurizing the vibrator by the pressurizing member and move relative to the vibrator; and an outputting member configured to output a driving force to the driven member, the driving force generated by the movement of the contacting member relative to the vibrator. The driven member includes an output transmission member configured to hold the outputting member in a direction of the relative movement with a predetermined spring force.
