Abstract
A displacement magnifying mechanism, polishing device, actuator, electronic component processing apparatus, dispenser, and air valve which can easily control a drive system. The displacement magnifying mechanism includes a base; a piezoelectric element of which an end is attached to a mounting surface of the base, the piezoelectric element extending along a first longitudinal direction; a support member of which an end is attached to the mounting surface side by side with the piezoelectric element, the support member extending along a second longitudinal direction which intersects with the first longitudinal direction; an operating portion attached to each of other ends of the piezoelectric element and the support member to allow the operating portion to be displaced, in response to an expansion/contraction of the piezoelectric element, along a displacement direction; and a compression member attached to the base and the operating portion so as to compress the piezoelectric element.
