Claims

[Claims for Utility Model Registration] (1) An insulating substrate having a first support portion at the center of the upper surface, and a second support portion fixed to the insulating substrate and facing the first support portion. an inverted U-shaped support frame having an inverted U-shaped support frame, two piezoelectric drive bodies fixed to face each other on substantially central inner surfaces of both sides of the support frame, and a wedge between the first support part and the second support part. a drive spring that is bent and supported; a drive member that is located in the center of the drive spring and has a flying member and an arm that contact one of the piezoelectric drive bodies; and a movable drive member that contacts the arm of the drive member. A piezoelectric relay comprising a contact spring and a fixed contact spring, and a contact spring assembly for fixing these lead-out terminals to the substrate, wherein a through hole is provided in the second support portion of the support frame, and the support frame is provided with a through hole. The cover is inserted into the drive spring by engaging with the outside of the drive spring, and the inner surface of the upper plate protrudes from the through hole by pressing down on the upper end of the drive spring to cause a curved displacement in the center of the drive spring. Features of piezoelectric relay. (2) The piezoelectric relay according to claim 1 of the utility model registration, wherein fitting means for fitting and fixing the lower part of the cover and the side surface of the substrate are provided at opposing positions.
