Abstract
A lens actuating module for realizing focus adjustment and optical zooming. The lens actuating module includes a rod which is disposed on one side of a lens barrel on which at least one lens is mounted, and has an axis direction corresponding to an optical axis direction of the lens barrel, a driving force transmission member which has a conjoining recess to be conjoined with an outside surface of the rod and has magnetism so as to be conjoined with the outside surface of the rod due to a magnetic force, and a piezoelectric actuator which is disposed on one side of the driving force transmission member in the optical axis direction to provide an axis direction driving force to the rod via the driving force transmission member.
