A piezoelectric/electrostrictive device is provided, including a rotor substantially in the form of a rectangular parallelepiped. The rotor has a pair of opposed surfaces, a first movable section fixed to a first end of one of the surfaces, a first piezoelectric/electrostrictive element for actuating the first movable section, and a second movable section fixed to a second end of the other one of the surfaces. The second end is diametrically opposed to the first end. A second piezoelectric/electrostrictive element for actuating the second movable section is also included.
