Lens actuating module

A lens actuating module comprising:

• 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;
• wherein the driving force transmission member includes a magnet in a horizontal magnetization pattern or a vertical horizontal magnetization, a first magnetic material which is disposed on one side surface of the magnet contacting the piezoelectric actuator to increase a magnetic force, and a second magnetic material which is disposed on the other side surface of the magnet opposite to the first magnetic material to increase the magnetic force, wherein the first magnetic material and the second magnetic material include a first conjoining recess and a second conjoining recess, respectively, to form the conjoining recess.
