ABSTRACT:
There is described a lens barrel including; a plurality of lens units; an actuator to move at least a lens unit included in the plurality of lens units; and a housing member. The actuator includes: a vibrating device constituted by two vibrating members, each of which includes piezoelectric elements aligned in a line, so that the two vibrating members intersect each other at a predetermined angle and vibrate in response to high-frequency electric signals; a driven member, coupled to the lens unit, to be moved by vibrations generated by the vibrating device; and a supporting member that is rotatably mounted on a shaft disposed opposite to the vibrating device in such a manner that the vibrating device press-contacts the driven member. The driven member is disposed at a side of the lens unit, while the vibrating device and the supporting member are disposed at a side of the housing member.
