Abstract:
A vibration wave driven apparatus includes a vibrator configured to generate vibration, a rotor configured to be in frictional contact with the vibrator and to rotate about an axis of rotation, and a transmitting member configured to rotate about the axis and to transmit rotation of the rotor to an external component. A part of the transmitting member forms a worm portion of a worm gear.
