Abstract: An electromagnetic lens driving device includes a casing, a lens module, a positioning structure, and an electromagnetic driving module. The lens module is provided in a receiving space defined in the casing. The positioning structure, which is connected between the lens module and the casing, is configured to limit the lens module within the receiving space and generate a frictional force. The electromagnetic driving module is provided in the receiving space and corresponds in position to the lens module. When supplied with electricity, the electromagnetic driving module generates a magnetic force that drives the lens module to move along a central axis. Once the electricity is cut off, the lens module is fixed in position and prevented from moving freely by the frictional force of the positioning structure; hence, the electromagnetic lens driving features economical use of electricity.
