ABSTRACT:
In a vibration wave motor disclosed in this specification, at least one straddling member is coupled to a vibration member along the direction of travel of a traveling vibration wave in such a manner as to straddle between two points having a spacing corresponding to (.lambda./2+n.lambda.) (n being an integer including zero), and the straddling member is rotatably coupled to a fixed member at the central position between the two coupling points of the straddling member.
