An optical apparatus is disclosed which can well maintain a surface
contact state between a vibrator and a contact member of a vibration type
linear actuator to perform a stable lens drive. The optical apparatus
comprises a vibration type linear actuator driving a lens in an optical
axis direction. The vibration type linear actuator includes a vibrator on
which vibration is produced through an electromechanical energy
conversion action and a contact member which is in press contact with the
vibrator. The apparatus comprises a holding mechanism which holds one
member of the vibrator and the contact member so as to change at least
one of the position and inclination of the one member in response to a
force smaller than a press contact force between the vibrator and the
contact member.
