Abstract: An articulated arm of the rear mirror for cars, bicycles and/or to that of an additional internal car rear mirror, suitable for efficient mounting either on the handlebar or inside the car and allowing for simple adjustment of the viewing position. The articulated rear mirror arm referred to in this invention allows for simple adjustment and arresting of the selected position by means of the articulated parts including the rod shaped structure of the carrier element, the intermediate connection element and the fixing element. The mirror is with its frame fixed to one end of the intermediate connection element, thereby forming an articulation.
