The return mechanism (15) for a steering wheel (10) comprises a first return spring (21) which exerts a first return couple on the wheel increasing over an initial range of the displacement from a reference position. A second return spring (30) comprising a cam (45) exerts a second return couple on the wheel having a maximum for a given displacement.
