摘要： A driving device includes an electro-mechanical transducer having first and second end portions opposite to each other in an expansion/contraction direction, a stationary member coupled to the first end portion of the electro-mechanical transducer, a vibration friction portion coupled to the second end portion of the electro-mechanical transducer, and a rod-shaped moving portion frictionally coupled to the vibration friction portion, whereby moving the moving portion in the expansion/contraction direction of the electro-mechanical transducer. The vibration friction portion is made of a material having a vibration transfer rate of 4900 meters/second or more. The moving portion is made of a material which has a vibration transfer rate of 4900 meters/second or more and which is different from that of the vibration friction portion.

摘要： A driving device includes an electro-mechanical transducer having first and second end portions opposite to each other in an expansion/contraction direction, a stationary member coupled to the first end portion of the electro-mechanical transducer, a vibration friction portion mounted to the second end portion of the electro-mechanical transducer, and a rod-shaped moving portion frictionally coupled to the vibration friction portion, whereby moving the moving portion in the expansion/contraction direction of the electro-mechanical transducer. The stationary member consists essentially of a base alloy which consists of, by weight, 88 to 97% tungsten, 2 to 11% nickel as a binder, and, as the balance, 0.1 to 2% at least one metal having an ionization tendency which is higher than that of tungsten. The stationary member has a surface without nickel plating.
