An optical mechanism, comprising:
- a movable module, for connecting an optical element, and comprising a holder, wherein the holder comprises:
- a hollow main body, having a connection surface;
- a restricting portion, having an upper surface and protruding outward from the main body in a horizontal direction perpendicular to an optical axis of the optical element;
- a fixed module, wherein the movable module may move relative to the fixed module within an moving range;
- a driving assembly, having a coil and a magnet for driving the movable module to move relative to the fixed module, wherein the restricting portion restricts the coil in a predetermined position on the holder;
- and
- a first resilient element, having a first connecting portion, a second connecting portion, and a deformable portion connecting the first connecting portion with the second connecting portion, wherein the first and second connecting portions respectively connect to the fixed module and the connection surface of the main body, and the upper surface faces the deformable portion;
- wherein when the movable module is located at any position within the moving range, the upper surface and the first resilient element are spaced apart from each other and at least partially overlap along the optical axis.
