Abstract

La présente invention porte sur un stabilisateur destiné à l'axe avant ou arrière d'un véhicule, comprenant une barre antidévers (1) droite ou courbe et, aux deux extrémités de celle-ci, une tête de connexion (2) en forme de bille partielle. Le stabilisateur selon l'invention est moins cher, notamment en termes de coût de fabrication, que les stabilisateurs connus dont est dérivée la présente invention. Cela tient au fait que les têtes de connexion (2) sont associées par liaison de matière avec les extrémités de labarre antidévers (1).
