ABSTRACT:
A vibration member generates a first bending vibration on a first plane and a second bending vibration on a second plane transverse to the first plane, and a moving member is driven with a combined vibration of the first and second bending vibrations generated on the first and second planes. The vibration member is machined, or made of different materials, so that the directions of respective natural vibration modes will be predetermined.
