ABSTRACT:
A driving device (actuator) 10 includes a driving shaft 16 which is Linearly driven in the axial direction by a piezoelectric element 15 and two disks 18a and 18b which are made of an elastic material and fixed to a rotary shaft 17. Peripheral portions of the two disks 18a and 18b vertically hold the driving shaft 16 between them so as to be frictionally coupled with the driving shaft 16 by their elastic forces. When the driving shaft 16 is linearly driven in the axial direction by the piezoelectric element 15, the peripheral portions of the two disks 18a and 18b receive a force in the tangential direction and rotate around the rotary shaft 17.
