PURPOSE:To move an element to be moved over the length of a movable driver by moving the driver in the traveling direction of a traveling wave in a contact part with a stationary base, and moving the element to be moved by the driver in the same direction as the traveling direction. CONSTITUTION:When a traveling wave of a circumferential direction indicated by an arrow D is generated on the surface of a movable driver 2, the driver 2 is moved in the traveling direction D of a traveling wave at the contact part with a stationary base 1 by reaction force, and an element 4 to be driven is moved in the same direction as the moving direction of the driver 2 by the wave at the contact part of the driver 2 with the element 4 to be driven. That is, the driver 2 is moved to one end side of the base 1 from the state before driving, and the element 4 to be driven is moved at a distance of the sum of the distance moved by the wave of the driver 2 and the moving distance of the driver 2. The moving speed of the element 4 to be driven at this time is twice as fast as the moving speed of the driver 2 as added to the speed of the driver 2 moved by the wave. |
