Abstract
A piezoelectric drive unit is configured for driving a passive element relative to an active element, wherein the active element includes a resonator with two arms, each extending in parallel to a reference plane and ending in a contact element, which is movable by oscillating movements of the arms and thereby drives the passive element. Each of the arms has, at the outer end of the arm, a protrusion extending inward, toward the other arm, and on at least one of the arms, the respective contact element, arranged at the arm's outer end, extends outward, away from the other arm.
