ABSTRACT:
In a lever-arm displacement-increasing device, two lever arms are joined at one end. The other end of one of the lever arms is connected to a fixed portion that supports the rear end of an actuator element, and the other end of the other lever arm is connected to a rigid connecting portion connected to the front end of the actuator element. The displacement force of the actuator element is transmitted to the lever arms through the connecting portion, and is further transmitted to a joint between the lever arms. The joint functions as an output displacing portion. The joint changes the displacing direction of the actuator element to a direction orthogonal thereto, and produces a displacement larger than the displacement of the actuator element.
