Abstract
The invention relates to a device for controlling the position of a member jointed to a support such as an automotive-vehicle external rearview mirror member movable about two axes substantially perpendicular to one another defined in the plane of the mirror member by, on the one hand, a common main rotary joint and, on the other hand, by two secondary rotary joints, respectively. Two locking means each associated with an axis of rotation are selectively unlockable to ensure the rotation of said mirror member about either axis of rotation under the single control of an electro-magnet.
