An actuator, comprising at least one beam capable of generating flexural oscillations, at least one pair of electric supply terminals () which supply oscillation-inducing electric power to the beam(s), and a holding mechanism which holds the beam(s), the holding mechanism including at least one holding member () to hold one portion of the beam(s) and a case () jointed to the holding member and configured to contain the beam(s) therein.

Actuator

An actuator, comprising a beam () including a laminated structure which has piezoelectric layers () and electrode layers (), a holding mechanism to hold the beam, a feeding terminal () to supply an exciting power to the electrode layers of the beam, and a contact mechanism provided in the holding mechanism, the holding mechanism comprising a case () including a space () to house the beam () and a holding part to hold at least one of an end and a central portion of the beam (), the contact mechanism being configured to contact with a part of the beam () and prevent the beam from excessively deflecting when a great impact is added to the beam.
