Claims

[Scope of utility model registration request]

Consisting of a first actuating rod, a frame, a second actuating rod, and a laminated piezoelectric element, the first actuating rod has one end connected to the frame via a first hinge, and the other end connected to the first actuating rod. attached to one end of the second operating rod via a flexible member;
The second actuating rod is attached to the frame via a second flexible member, and the laminated piezoelectric element has one end fixed to the frame and the other end attached to the first actuating rod via a second hinge. The actuator is attached to the actuator to magnify the displacement of the laminated piezoelectric element due to the piezoelectric effect and transmit it to the second actuating rod, the actuator relaxing the bending stress in the central part of the first and second flexible members. An actuator characterized by forming a through hole portion for the purpose of the actuator.
