<p>The invention relates to a mechanical driving system, mainly intended for a wiper, of the type comprising a first part (1) to be attached to a driving shaft and rotated about a rotation axis, and a second part (2) provided at least partially inside the first part (1) coaxially relative to the rotation axis, the system being attached at a fixation point (R) outside the mechanical system so that, during the operational state of the system, said second part (2) is immobile when said first part (1) is rotated. According to the invention, an indexing spigot (3) inside the system can assume two stable positions via a translation movement parallel to the rotation axis inside the system, i.e. a locking position for rotationally linking the first and second parts and an unlocking position allowing a relative rotational movement between said first and second parts (1, 2).</p> |
