Driving apparatus using transducer

摘要

A driving apparatus having an electromechanical transducer which extends and contracts; a first member connected to one end of the electromechanical transducer; a driving frictional member which is formed of a ceramic material and is connected to the other end of the electromechanical transducer; and a second member frictionally coupled with the driving frictional member, whereby either one of the first or second object is fixed and the electromechanical transducer is made to extend and contract, thereby driving in a specified direction the member which is either the first or second member and is not fixed.
