Articulation device with parallel structure including: a fixed base (1); an element (2) which can move with respect to the base (1) and is separated from it; several actuators (3) interposed between the base (1) and the movable element (2), each of these actuators being connected to the movable element by an articulation (9) and being capable of moving individually with a concomittant movement (closer together or further apart) of the articulation (9) of the actuator (3) on the movable element (2) with respect to the base (1), characterised in that the actuators (3) are four in number, and in that the movable element (2) exhibits a central pivot point (0) located between the articulations (9) of the four actuators. <IMAGE>
