を特徴とする圧電素子変位拡大機構。 A mounting board, two lever arms that transmit and expand the displacement of the piezoelectric element, a hinge that connects each lever arm and the piezoelectric element, a hinge that connects each lever arm and the mounting board, and two lever arms that are clamped together by both lever arms. In the piezoelectric element displacement magnifying mechanism, each end of which is connected to a lever arm as a displacement magnifying means, the piezoelectric element displacement magnifying mechanism is composed of a beam serving as a displacement magnifying means, each end of which is connected to a lever arm. Press punch out multiple sheets, then punch out half or all the way around the two lever arms and the mounting board at key points to form caulked parts of any shape, and stack them one by one with scissors. , a piezoelectric element displacement magnifying mechanism characterized by having a structure in which the half-cut protrusions of the caulking part are closely laminated by the frictional force of the cut surfaces.
