Displacement Member, Driving Member, Actuator, and Driving Device |
摘要 |
A displacement member with a driving element that includes first and second side surfaces that extend in a first direction and top and bottom surfaces that extend in a second direction perpendicular to the first direction. The driving element is a piezoelectric element that expands and contracts in the second direction when a pulsed voltage is applied. Further, an elastic conversion element is provided that contains the driving element and includes a first portion that is disposed adjacent the top surface of the driving element and that includes a displacement portion that is displaced downwardly and upwardly in the first direction when the driving element expands and contracts in the second direction, respectively.
