PROBLEM TO BE SOLVED: To effectively transfer a driving force of a vibration actuator to a rotating member. SOLUTION: This driving apparatus is provided with a vibration actuator 10, which extracts a driving force from a plurality of driving force extracting portions formed at the predetermined positions of a vibrator, by generating a plurality of vibrations to a vibrator with the impressing of an AC voltage, a plurality of rotating members 2a, 3a which are provided respectively in contact with a plurality of driving force extracting portions of the vibration actuator 10 and are driven with the driving force and a base member 1 for supporting to rotate the rotating members 2a, 3a. At least one of the rotating members is formed as a curving surface at the surface, in contact with the driving force extracting portion. |
