Claims

[Scope of utility model registration request]

A piezoelectric drive body in which a plurality of piezoelectric elements each having electrodes provided on both sides of a rectangular thin plate-shaped piezoelectric body are laminated, and a voltage is applied to generate elongation displacement in a direction perpendicular to the surface of the piezoelectric body; and the piezoelectric drive body. A drive element disposed on a first end surface parallel to the surface of the piezoelectric element of the body, a base portion disposed with a second end surface opposite to the first end surface of the piezoelectric drive body, and a plate-shaped support hinge spring having a first end fixed to the base; a first end surface in the longitudinal direction fixed to a second end in the longitudinal direction of the first support hinge spring; One side surface of the piezoelectric driver is fixed to the base portion by pressure contact through the driver surface, and a second end surface opposite to the first end surface is configured to apply a voltage to the piezoelectric driver. a first arm portion in the shape of a cylindrical member that moves more than the displacement of the elongation of the piezoelectric drive body; a second support hinge spring having an end fixed to the base part; a second support hinge spring having a second cylindrical shape fixed to a first end in the longitudinal direction and a second end in the longitudinal direction of the second support hinge spring; the arm of the second arm, keeping a predetermined distance from the second support hinge spring and extending the first end of the second arm in the longitudinal direction parallel to the first end of the second support hinge spring.
a second drive hinge spring fixed to the end of the support hinge spring with a step difference therebetween and fixed to the second end surface of the first arm, and a displacement magnifying mechanism that largely moves a second end surface of the second arm; and a displacement magnifying mechanism that is provided near the second end surface of the second arm of the displacement magnifying mechanism, parallel to the second driving hinge spring. a movable contact that moves to the fixed contact and a fixed contact disposed opposite to the movable contact; when a voltage equal to or higher than a predetermined voltage is applied to the piezoelectric driver, the movable contact contacts the fixed contact; In the piezoelectric relay in which the movable contact leaves the fixed contact when the voltage applied to the piezoelectric driver is less than a predetermined value, the piezoelectric relay is further provided on a surface of the piezoelectric driver opposite to a surface on which the driver is disposed. A fixing member, a planar fixing part provided on the fixing member and perpendicular to the surface of the piezoelectric body, and sliding on the surface with the fixing part in contact with each other, and the piezoelectric drive body 1. A piezoelectric relay comprising: a guide surface that fixes the fixing member to the base portion by fixing the fixing portion when pressed by the arm portion of the piezoelectric relay.
