Abstract: A multiple lenses driving mechanism is provided, including a frame, a first lens holder, a second lens holder, a first lens driving assembly, a second lens driving assembly and a stopper. The first and second lens holders are disposed in the frame, arranged along a longitudinal axis for respectively holding a first lens and a second lens. The first lens and the second lens define a first optical axis and a second optical axis, respectively. The first and second lens driving assemblies are disposed in the frame to drive the first lens holder and the second lens holder, respectively. The stopper is disposed between the first and second lens holders and has a first restricting surface and a second restricting surface, facing the first and second lens holders, so as to restrict the first and second lens holders in a first restricted position and a second restricted position.
