Abstract
In a vibration type motor, a vibrator unit including a vibrator configured to vibrate, and a friction member unit including a friction member which the vibrator contacts relatively moving in a first direction. The vibrator unit is displaceable relative to the friction member unit in a second direction orthogonal to the first direction, and presses the vibrator against the friction member in the second direction. The friction member unit includes a stopper that contacts the vibrator unit so as to restrict the vibration unit from displacing, by an amount exceeding a predetermined amount, in the second direction. The stopper extends in the first direction, a distance greater than a length, in the first direction, of an area of the friction member which the vibrator contacts, and the stopper projects from the friction member toward the vibrator in the second direction when viewed from the first direction.
