Abstract
An anti-twist structure of a voice coil motor includes a base, a lens housing, a first elastic sheet, a second elastic sheet, a magnet, and a yoke member. The lens housing has first margin wall and a second margin wall, and a first protrusion extends from the first margin wall. The yoke member has a first wall, a connection wall, a second wall, and a side wall. The first wall is disposed above the first protrusion, and the second wall is above the first margin wall. The lens housing has a deflectable angle relative to a horizontal reference line. When the lens housing deflects to a maximum value of the deflectable angle, the first margin wall abuts against the second wall and/or the first protrusion abuts against the first wall.
