る。Structure of the conventional example and its problems A conventional piezoelectric device of this type is structured as shown in FIGS. 1 and 2. That is, a pad 5 and a piezoelectric element 4 are placed inside an outer case 1 made of synthetic resin.
An inner case 2, which constitutes an impact mechanism using a hammer 8, a hammer spring 9, etc., is slidably attached to the outer case 1.
In addition, a return spring 6 for returning the inner case 2 is built into the outer case 1.
The area around the piezoelectric element 4 inside is fixed with an adhesive 7.
