Abstract
An actuator using an electro-mechanical transducer, the actuator comprising: the electro-mechanical transducer; a fixed portion securely coupled to one end of the electro-mechanical transducer to securely hold the electro-mechanical transducer; a driving member securely coupled to the other end of the electro-mechanical transducer to be displaced together with the electro-mechanical transducer; a member to be driven which is frictionally coupled to the driving member; and a support member for supporting one end of the driving member such that the driving member is movable in the direction of expansive or contractive displacement of the electro-mechanical transducer, wherein reciprocal vibrations are produced at different speeds in the driving member by causing the expansive or contractive displacement with the application of a drive pulse to the electro-mechanical transducer such that the member to be driven that is frictionally coupled to the driving member is thereby moved in a specified direction, and one end of the driving member is adhered to the support member with an adhesive agent having viscoelasticity.
