<p>A precise and high load resistance moving method and device is provided, in which a piezoelectric element which generates a shear deformation and a wedge, or, a piezoelectric element which generates a shear deformation, a piezoelectric element which generates a vertical deformation, and a wedge are combined, and a moving body can be precisely moved in a perpendicular direction even when large force is applied to a sliding surface. A precise and high load resistance moving method and device is provided, in which by layering piezoelectric elements which generate shear deformations so that their shear directions differ, and by combining with a wedge, a moving body can be precisely moved in a perpendicular direction even when large force is applied to a sliding surface. A wedge-shaped moving element 23 arranged on a surface in a horizontal direction of a fixed body, and to which a piezoelectric element 24A which generates a shear deformation is fixed, a pulse source 30 for rapidly deforming and driving the piezoelectric element 24A, and a moving body 25 which contacts a wall surface 22 of the fixed body in the perpendicular direction by a drive of the wedge-shaped moving element 23 and moves in the perpendicular direction are provided, and by striking or extracting the wedge-shaped moving element 23 to/from the moving body 25, a movement positioning of the moving body 25 is performed.</p> |
