ABSTRACT:
In a vibration wave motor for driving a movable member which contacts with a vibration member which in turn contacts an electrostrictive element, by a travelling vibration wave generated in the vibration member by applying periodic voltages to the electrostrictive element, the periodic voltages are applied to the electrostrictive element in the same direction as the amplitude direction of the travelling vibration wave to obtain a longitudinal effect so that drive efficiency is improved.
