<P>PROBLEM TO BE SOLVED: To obtain stable frequency characteristics. <P>SOLUTION: A driving device (20) includes an electro-mechanical transducer (441) having first and second end portions opposite to each other in an expansion/contraction direction, a static member (442) coupled to the first end portion of this electro-mechanical transducer, a vibration friction portion (443) mounted on the second end portion of the electro-mechanical transducer, and a rod-shaped moving portion (423) frictionally coupled to the vibration friction portion, whereby capable of moving the moving portion (423) in the expansion/contraction direction of the electro-mechanical transducer (441). The driving device (20) is covered with a cabinet (30), and an elastic member (446) lies between the cabinet (30) and the static member (442). The elastic member is constituted from sheet metal (446) disposed separated by a predetermined distance form the cabinet (30) and fixed to the static member (442). <P>COPYRIGHT: (C)2009,JPO&INPIT |
