Abstract
An imaging lens driving module includes a lens system, a lens holder accommodating optical lens elements of the lens system, a base, a rollable support assembly and a driving mechanism. The base includes first and second guiding grooves extending in a direction parallel to the optical axis, disposed opposite to each other and facing the lens holder. The rollable support assembly is in physical contact with and disposed between the lens holder and the base and includes principal and auxiliary rollable support elements. The principal rollable support element is disposed between the lens holder and the first guiding groove. The auxiliary rollable support element is disposed between the lens holder and the second guiding groove. The driving mechanism is configured to drive the lens holder to move. Diameters of the principal and auxiliary rollable support elements in physical contact with the lens holder are different from each other.
