Joystick comprising: - an articulation (26) comprising bearing faces (32, 34) shaped to allow, by form cooperation when they rub against each other, a rotation movement of a handle (4 ), - a first set (120) of springs exerting on the handle a first vertical force which pushes the bearing faces (32, 34) one against the other; - a second set (122) of springs exerting on the handle a second vertical force in a direction opposite to the first vertical force and the amplitude of which is between 0.9 | F1 | and 1,1 | F1 |, where | F1 | is the amplitude of the first vertical force, and - the first and second sets (120, 122) of springs are capable, in the absence of external stress on the handle (4), of maintaining a clearance (J) not zero between all the bearing faces of the joint.
