摘要：A driving device includes an electro-mechanical transducer having first andsecond end portions opposite to each other in an expansion/contraction direction, astationary member coupled to the first end portion of the electro-mechanical

transducer, a vibration friction portion mounted to the second end portion of theelectro-mechanical transducer, and a rod-shaped moving portion frictionally coupled tothe vibration friction portion, whereby moving the moving portion in the

expansion/contraction direction of the electro-mechanical transducer. A frictionallycoupled portion has a height (a length of the vibration friction portion in a slidingdirection in contact with the moving portion) which is not more than 1.15 mm.
