The present invention provides a driving module for a head up display (HUD) comprising: a driving motor which is driven by a driving signal from a control unit; a lead screw which is connected with the driving motor and rotated when driven by the driving motor; a movable link which is coupled with the lead screw by a screw and moved along an axial direction of the lead screw when the lead rotates; and a coupling member which couples a mirror unit, which is arranged to rotate around a rotational axis, with the movable link and rotates the mirror unit when the movable link moves. The coupling member is characterized in coming into surface contact with the movable link. According to the present invention, durability and driving performance of the driving module can be improved. |
