Abstract
A driving mechanism is provided, including a housing, a hollow frame, a holder, and a driving assembly. The frame is fixed to the housing and has a stop surface. The holder is movably disposed in the housing for holding the optical element. The driving assembly is disposed in the housing to drive the holder and the optical element moving along the optical axis of the optical element relative to the frame. Specifically, the stop surface is parallel to the optical axis to contact the holder and restrict the holder in a limit position.
