Patent attributes
A vibration wave motor includes a first holding member; a second holding member; a first regulating region; and a second regulating region, wherein a position of a first contact region of the first holding member, which comes into contact with the first regulating region, is different from a position of a second contact region of the second holding member, which comes into contact with the second regulating region, and wherein a position of the first regulating region is different from a position of the second regulating region in the relative movement direction so that, in the relative movement direction, a difference between a distance from the first contact region to the first regulating region and a distance from the second contact region to the second regulating region is shorter than a difference between the position of the first contact region and the position of the second contact region.
