Abstract:
A vibration type driving apparatus is provided, in which a plurality of vibration members include rotation units that are formed so as to be rotatable around respective rotation axes that are parallel to respective directions of forces generated by elliptical movements; in which any vibration member that is positioned in a range where an angle between a direction of movement of a moving member and the corresponding rotation axis is greater than a predetermined angle is tilted by the rotation unit, and vibration mode for push-up moving is generated at the any vibration member; and in which the elliptical movement of any vibration member that is positioned in a range where the angle is less than the predetermined angle causes the moving member to move.
