Abstract
A vibration-type driving device according to the present invention includes a plurality of vibrators in which contact portions perform an elliptical motion using a combination of vibrations in different vibration modes; and a driven object having contact regions that come into contact with the contact portions and move relative to the plurality of vibrators, wherein the contact regions for the individual vibrators differ in position so as not to overlap.
Claims6
A vibration-type driving device comprising:
- a first vibrator comprising a first contact portion and a second vibrator comprising a second contact portion, wherein a combined vibration of vibrations in different vibration modes is excited in each of the first vibrator and the second vibrator;
- a driven object comprising:
- a first contact region that comes into contact with the first contact portion;
- and
- a second contact region that comes into contact with the second contact portion,
- wherein the first vibrator and the second vibrator are configured that the first contact region and the second contact region are adjacent to each other in a direction perpendicular to at least one of a direction of relative movement of the driven object and the first vibrator and a direction of relative movement of the driven object and the second vibrator.
