Patent ID: 7482734

Claim:
A piezoelectric/electrostrictive device comprising: a rotor substantially in the form of a rectangular parallelepiped, said rotor having a pair of opposed surfaces; a first movable section fixed to a first end of one of said surfaces; a first piezoelectric/electrostrictive element for actuating said first movable section; a second movable section fixed to a second end of the other one of said surfaces, said second end being diametrically opposed to said first end; a second piezoelectric/electrostrictive element for actuating said second movable section; a first base having a first fixing member and a first thin plate and a second thin plate which face each other and extend from said first fixing member; and a second base having a second fixing member and a third thin plate and a fourth thin plate which face each other and extend from said second fixing member; wherein said first movable section is provided as an end of said first thin plate or said second thin plate of said first base; wherein said second movable section is provided as an end of said third thin plate or said fourth thin plate of said second base; wherein said first piezoelectric/electrostrictive element extends over and is fixed to at least one of said first thin plate and said second thin plate and said first fixing member; and wherein said second piezoelectric/electrostrictive element extends over and is fixed to at least one of said third thin plate and said fourth thin plate and said second fixing member.
