ABSTRACT:
A vibration driven motor of a construction in which the hardness of the sliding surface of a vibration member is lower than the hardness of the sliding contact portion of a member brought into pressure contact therewith, and the lateral width of the sliding contact portion of the vibration member is smaller than the width of the sliding contact portion of the member brought into pressure contact therewith, whereby the sliding member of the vibration member is caused to wear more than the sliding member of the member brought into pressure contact therewith, thereby to facilitate the discharge of the wear powder thereof and to eliminate the level difference wear of the movable member attributable to the comb-shaped projections and the deterioration of the planarity of the movable member similar thereto. Also, this structure prevents deterioration of accuracy in motor performance when a stopping or starting operation occurs at the same location, or when operating at extremely low speed control is effected, and abnormal wear of the sliding surface of the vibration member is prevented.
