Patent ID: 7247973

Claim:
A moving mechanism using a piezoelectric actuator, comprising: a piezoelectric element constituting the piezoelectric actuator; a movable part moved by the piezoelectric actuator; and a support part supporting the piezoelectric actuator, wherein at least one of said movable part and said support part is fixed to said piezoelectric element, and at least one of said piezoelectric element, said movable part and said support part has a bonding surface that is defined by a level difference, and wherein said piezoelectric element includes a fixed part fixed by an adhesive to one of said movable part and said support part and an active part that is not fixed and deformable, and said level difference is provided between the fixed part and the active part so that a distance between a surface of said active part and one of a surface of said movable part and a surface of said support part is larger than a distance between a surface of said fixed part and one of the surface of said movable part and the surface of said support part.
