ABSTRACT:
A vibration driven motor includes guide grooves formed in two side surfaces of a rail shaped stator along a prospective moving direction, and a pair of first roller bearings to be fitted in one guide groove and arranged at front and rear portions in the moving direction of one side surface of a movable base operatively fixed to a vibrator. A second roller bearing is fitted in the other guide groove and arranged to be located between the first roller bearings. A first urging member engages the first guide follower, for urging the first guide follower to follow the first guide surface, and a second urging member engages the second guide follower, for urging the second guide follower to follow the second guide surface.
