ABSTRACT:
A driving device according to the present invention includes an electromechanical transducer secured at its one end to a stationary body, a driving frictional member secured to the other end of the electromechanical transducer, and a moving body which frictionally engage with the driving frictional member. The moving body has a length smaller than the total length of the stationary body, the electromechanical transducer5and the driving frictional member. The moving body moves such that it extends beyond the lengthwise end portions of the driving frictional member.
