Piezoelectric/electrostrictive device
First Claim
1. A piezoelectric/electrostrictive device comprising:
- a base being constructed with one sheet of flat plate, the base having a fixing part of a flat plate shape, a mounting part that is separate from the fixing part and having a flat plate shape, and a pair of left and right movable parts, the pair of movable parts each being supported at one end side thereof by each side edge of the fixing part and at the other end side thereof by each side edge of the mounting part, the respective movable parts being erect by a predetermined height from side edges of the fixing part and the mounting part to face each other and extend along the side edges of the fixing part and the mounting part, and a piezoelectric/electrostrictive element arranged on an inner side of at least one of the pair of left and right movable parts.

Abstract
A piezoelectric/electrostrictive device that includes a base 11 having a pair of right and left movable parts 11a, 11b and a fixing part 11c disposed at one end thereof as well as piezoelectric/electrostrictive elements 12a, 12b disposed on the sides of the movable parts 11a, 11b of the base 11 is fabricated to have a construction with fewer components. The piezoelectric/electrostrictive device having a construction with fewer components is provided by adopting a base 11 having an integral structure formed by bending an original plate stamped into a shape that delineates a plane development of the base, as the base of the piezoelectric/electrostrictive device. In addition, in this piezoelectric/electrostrictive device, piezoelectric/electrostrictive elements are arranged on inner sides of a pair of left and right movable parts. Accordingly, destruction of the piezoelectric/electrostrictive element can hardly occur and high reliability of the piezoelectric/electrostrictive device is achieved.
