Abstract: The anti-twist structure includes a base, a lens housing, an elastic sheet and a yoke member. The lens housing has a margin wall with a first protrusion, a second protrusion and a contact portion. The contact portion is extended outwardly the first protrusion, and the second protrusion is protruded from the contact portion. The first protrusion and the second protrusion are protruded along an axial direction substantially perpendicular to the margin wall. The elastic sheet is disposed on the contact portion. When the lens housing deflects from the horizontal reference line to a maximum value of the deflectable angle, the first protrusion abuts against an upper wall of the yoke member, the second protrusion abuts against the elastic sheet, and the contact portion abuts against the elastic sheet or the upper wall at the same time, whereby the lens housing and the yoke member interfere with each other.
