ABSTRACT:
A displacement generating apparatus having a gate-shaped structure is provided in which a plurality of bimorph-type piezoelectric elements are employed. The gate-shaped apparatus has high rigidity and a high resonance frequency, and can produce a carrying force greater than that of the conventional counterpart. Thus, the apparatus can move a heavier object at a high speed very accurately.
