Abstract:
A vibration type driving device includes a vibrator configured to make an elliptic motion of a contact portion by combining vibrations in different vibration modes, and a driven body configured to be rotated relative to the vibrator by the elliptic motion while being in contact with the contact portion. A contact pressure of the contact portion with the driven body is lower on a radial inner side than on a radial outer side in a radial direction of the rotation.
