To provide a displacement enlarging mechanism which can perform the positional adjustment of an output end more easily without using a washer or a shim.
The displacement enlarging mechanism 21 is equipped with an actuator 23 which has a piezoelectric actuator element, link bodies 27 which receive the displacement for drive generated in the actuator, an output body 31 which finally outputs the displacement, lever bodies 29 which enlarge the displacement inputted from the link bodies and transmit it to the output body, and an adjustment screw 103 which adjusts the output body by shifting at least either the actuator or the link bodies in the displacing direction. The adjustment screw engages in the link body and also abuts on the actuator capably of mutual rotation at a nonthreaded part.
