Patent ID: 8335055

Claim:
A head suspension having a load beam and a piezoelectric actuator, the piezoelectric actuator supporting a base part of the load beam and configured to displace a front end of the load beam in a sway direction, the head suspension comprising: the piezoelectric actuator having an actuator base and at least a piezoelectric element, the actuator base connected to the base part of the load beam and having at least an opening, the piezoelectric element attached to the opening and deforming in response to a voltage applied thereto to conduct displacement of the front end of the load beam; a circumferential side face of the piezoelectric element; a circumferential edge of the opening, configured to define the opening in the actuator base and surround and face the circumferential side face of the piezoelectric element; a bottom receiver formed at the opening, configured to face the periphery of a bottom face of the piezoelectric element; a clearance splitting the circumferential edge of the opening and the bottom receiver, configured to allow the piezoelectric element to deform; and a nonconductive adhesive applied at least between the circumferential edge of the opening and the circumferential side face of the piezoelectric element and between the bottom receiver and the bottom face of the piezoelectric element, configured to adhere the piezoelectric element to the opening.
