Claims

[Claims for Utility Model Registration] (1) A plurality of piezoelectric elements are integrally stacked such that internal electrodes are alternately located between them, and mechanical strain caused by expansion and contraction of these piezoelectric elements in the stacking direction due to an electric field is caused. a piezoelectric drive body having a drive element at one end and a fixing part at the other end, a drive board fixing the fixing part of the piezoelectric drive body, and a hinge spring fixed to the drive board at one end with a hinge spring. a displacement amplifying mechanism having a drive protrusion at the other end that moves the drive element by pressing the drive element against the middle part of the arm body connected to the arm body, and expands the displacement of the drive element based on this principle; a fixing body having a fixing surface to be installed, a fixing surface fixing to the driving board, and a fitting protrusion formed on the fixing surface, and the driving board has a guide surface fixing the fixing surface of the fixing body; A piezoelectric relay comprising a fitting hole formed on the guide surface to face the fitting protrusion. (2) Utility model registration claim No. (1) in which part or all of the drive board, arm body, fixed body, and hinge spring are made of engineering plastic material.
Piezoelectric relay described in section. (3) Utility model registration claim 1 or 2, in which the fitting protrusion is formed on the guide surface of the drive board, and the fitting hole is formed on the fixing surface of the fixed body. piezoelectric relay.
