1. A lens driving device, comprising:
a case having an accommodation space; and
a lens module accommodated in the accommodation space,
wherein the lens module comprises:
a lens; a lens holder receiving the lens;
a support frame, support members, and an electromagnetic driving device, for freely rotating the lens holder in a direction orthogonal to an optical axis direction; and
a base for fixing a circuit board,
wherein the electromagnetic driving device is arranged on the lens holder and the base for fixing the circuit board, and is arranged adjacent to a level of a center of gravity of the lens module, and
wherein the lens module has different movement axes in a plane and is rotatable freely relative to the base for fixing the circuit board;
wherein the support members are shaft pins, and at least four shaft pins are provided;
the base has a groove that limits a direction of the shaft pins, through rolling of the shaft pins, the lens module can freely rotate in two different rotation directions that are limited;
the axial directions of the shaft pins are parallel to the optical axis direction.
