ABSTRACT:
A precise and high load resistance moving method to perform fine movement positioning of the moving body, by fixing a piezoelectric element which generates a shear deformation, to a bottom surface of a wedge-shaped moving element placed on a base, and deforming the piezoelectric element by driving the piezoelectric element with drive pulses to move the wedge-shaped moving element along a first axis in which the wedge-shaped moving element drives into or away from a moving body to move the moving body along a second axis in upward and downward direction relative to the base. Also, a precise and high load resistance moving device including a wedge-shaped moving element, a pulse source, and a moving body vertically movable in upward or downward direction relative to the base.
