Abstract
A variable aperture module includes a blade assembly, a positioning element, a driving part and pressing structures. The blade assembly includes movable blades disposed around an optical axis to form a light passable hole with an adjustable size. Each movable blade has a positioning hole and a movement hole adjacent thereto. The positioning element includes positioning structures disposed respectively corresponding to the positioning holes. The driving part includes a rotation element disposed corresponding to the movement holes and is rotatable with respect to the positioning element. The pressing structures are disposed respectively corresponding to the movable blades. Each pressing structure is at least disposed into at least one of the positioning hole and the movement hole of the corresponding movable blade. Each pressing structure at least presses against at least one of the corresponding one positioning structure and the rotation element.
