Abstract
In a mechanical amplification mechanism for piezoelectric elements, a pair of lever arms, base block and a pair of fulcrum portions connecting therebetween are structured with a lamination of thin metal plates of a predetermined number. Each of thin metal plate has the thickness smaller than the width of the fulcrum portions and they are laminated such that the total thickness is larger than the width of the fulcrum portions. The lamination strength of thin metal sheets is improved by either caulking predetermined positions or inserting a bonding material between every thin metal plates.
