A driving apparatus, comprising a piezoelectric actuator (118) having a tip (108) displaceable in X,Y,Z three-axis directions, and a movable body (111) having translational movement freedom in X,Y two-axis directions, wherein the tip of the actuator is placed to be displaceable in Z-axis direction to come into pressure contact with the movable body, and the tip of the actuator under pressure contact is displaced within an XY-axis plane to move the movable body translationally in the direction of displacement of the tip of the actuator. |
