Abstract: A lens shift backlash elimination device includes a base, a transmission mechanism, and a lens. The transmission mechanism is disposed on the base and includes a first element, a second element, and an elastic element. The second element is mechanically connected to the first element. The elastic element is disposed between the first element and the second element, or abutted against the first element. The lens is mechanically connected to the transmission mechanism. The lens may be displaced relative to the base in a first direction.
