ABSTRACT:
A vibration wave motor, in which a periodic voltage is applied to an electrostrictive element to generate a travelling vibration wave in the surface of a vibration member thereof, and in which a movable member having a friction member is driven on the vibration member by the vibration wave, includes a guide member for controlling the direction of displacement of the movable member, the guide member being disposed to prevent the movable member from being displaced in directions other than a predetermined direction of movement, and a flexible member connecting the movable member and the friction member.
