Abstract

A driving apparatus includes an electromechanical transducer that is connected to a drive pulse generating means and that expands and contracts, a driven member that is connected to one end of the transducer, a friction member that is connected to the other end of the transducer and a guide unit that is in frictional contact with the friction member. The friction member has an elastic deforming mechanism that elastically presses against and comes into frictional contact with the guide unit, and the elastic deforming mechanism is constructed such that its elastic deformation stress vector perpendicularly crosses the directions of expansion and contraction of the transducer.
