Abstract
A vibration-wave motor includes a vibrator, a first holding member configured to hold the vibrator, a second holding member configured to hold the first holding member, a plurality of pressing members arranged around the vibrator and configured to press the vibrator against a contacting member that contacts the vibrator, a movable plate disposed opposite to the vibrator with respect to the contacting member, and a coupling part configured to couple the second holding member and the movable plate with each other. The vibrator and the contacting member move relatively to each other due to a vibration generated by the vibrator. One of the second holding member and the movable plate includes a transmitting part configured to transmit a driving force of the vibration-wave motor to a driven member.
