Abstract
Disclosed herein is a lens actuating module. In the lens actuating module, a housing has an installation space therein. A lens barrel is disposed in the installation space of the housing. The lens barrel includes a lens. An actuating means is provided at a first position in the installation space of the housing in an optical axial direction. The actuating means is connected to the lens barrel to move the lens barrel. A base magnet is provided at a second position in the installation space of the housing. A lens magnet is mounted to the outer surface of the lens barrel at a position facing the base magnet to generate a repulsive force between the lens magnet and the base magnet.
