Abstract: The invention discloses a steering device comprising a support structure having a central hole and at least two handgrips, at least one of these being mobile, placed in distal positions compared to the central hole and tied to the support structure by means of pivots. The mobile handgrip is rotatable around an axis substantially orthogonal to the plane of the support structure, so as to manually apply thereto a rotating motion around the axis of the column.
