摘要：An actuator includes a piezoelectric element (12), and a displacement
enlargement mechanism (14) which has a movable portion configured to be displaced asthe piezoelectric element is displaced and enlarges an amount of displacement of the
piezoelectric element. A restraint member (30) is fixed to the movable portion with anelastic or viscoelastic body (32) therebetween and convert vibrational energy of themovable portion into thermal energy based on deformation of the elastic or viscoelasticbody, thereby lowering a resonance peak amplitude of the actuator.
