A motor includes a vibrator, a contact member that contacts the vibrator, a first pressing unit that applies a pressing force in a first direction to the vibrator to bring the vibrator into contact with the contact member, a first holding member that holds the vibrator, a second holding member that holds the first holding member, and a second pressing unit that applies to the first holding member a pressing force in a second direction in which the vibrator and the contact member are displaced relative to each other by generated thrust. The first and second holding members contact each other in the second direction due to the pressing force of the second pressing unit. The first and second holding members are movable relative to each other in the first direction by the pressing force of the first pressing unit.
