Title: Piezoelectric actuator
Inventor: WATANABE SEIJI
IPC: H01L41/083
Filed: 1999-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric actuator which can be driven in a desired direction, and to simplify its manufacturing process. SOLUTION: This piezoelectric actuator is composed of a displacement mechanism part 1, which is composed of a large displacement end 2 and a small displacement end 3. The piezoelectric actuator is composed of a piezoelectric element for drive, which is pasted to the large displacement end 2 on one face of the displacement mechanism part 1. The piezoelectric actuator is composed of a moving body 5, which comes into contact with the other face of the displacement mechanism part 1. When a drive signal is input to the piezoelectric element 4 for drive, which is pasted to the large displacement end 2, a large displacement is caused on the side of the large displacement end 2, and a displacement on the side of the small displacement end 3 is reduced.  Due to their displacement difference, a difference is generated in a frictional force to the moving body 5 between the side of the large displacement end 2 and the side of the small displacement end 3. Due to their frictional differences, moving body 5 can be driven in the desired direction from the side of the large displacement end 2 to the side of the small displacement end 3.
