Claims

[Scope of utility model registration request]

One end of a first piezoelectric (or electrostrictive) element having a certain height is fixed to a reference plane, a support member is fixed to the other free end, and the side of the support member on which the first piezoelectric element is provided. A differential actuator characterized in that one end of a second piezoelectric element having a constant height is fixed.
