Electromechanical transducer and actuator

摘要

An electromechanical transducer that includes an elongating/contracting member and a driving member. The elongating/contracting member elongates and contracts in response to application of a voltage thereto. The elongating/contracting member has a side surface that is parallel to an elongation/contraction direction. The driving member is provided on the side surface of the elongating/contracting member. The driving member is displaced with elongation and contraction of the elongating/contracting member.
