摘要 |
In a vibration wave driven motor disclosed herein, the arcuate portions of the vibration member thereof are formed into a shape in which flexural rigidity differs between the inner side and the outer side thereof, or a shape in which the torsional rigidity of the straight portions of the vibration member is made higher than the torsional rigidity of the arcuate portions, whereby a torsion component produced in the straight portions is made small by the straight portions.
