A device for a vehicle adjustable rear-view mirror is provided, wherein the device includes a fixed portion as well as a mirror support capable of pivoting relative to the portion using a driving motor and at least one driving gear. Also a potentiometer is used for generating a signal that indicates the pivot angle between the fixed portion and the mirror support which is considered as a module. The potentiometer includes a resistive member and a wiper, one of which is coupled to a base member attached to the fixed portion while the other is connected through a friction coupling to the driving gear or to a rotating part that co-operates with the same. One of those two members comprises two abutments having an angular deviation that corresponds to the pivot angle, the fixed portion and the mirror support, while the other member comprises two counter-abutments that co-operate with said abutments.
