Bending actuator having beam-deflection limiting structure |
摘要 |
<p>An actuator, comprising a beam (2) including a laminated structure which has piezoelectric layers and electrode layers, a holding mechanism to hold the beam, a feeding terminal (10) to supply an exciting power to the electrode layers of the beam, and a contact mechanism (50) provided in the holding mechanism, the holding mechanism comprising a case (1) including a space (5) to house the beam (2) and a holding part (6) to hold at least one of an end and a central portion of the beam (2), the contact mechanism being configured to contact with a part of the beam (2) and prevent the beam from excessively deflecting when a great impact is added to the beam. <IMAGE></p> |
