Abstract

Le mobile comprend une zone centrale (2) rigide pourvue d'une ouverture (4) de chassage et des bras (6) s'étendant radialement depuis la zone centrale (2) vers une zone périphérique comportant des dents (8). Les bras (6) sont flexibles pour permettre un faible déplacement tangentiel et radial des dents afin d'absorber des chocs. L'invention est caractérisée en ce que les bras sont courbes et s'infléchissent progressivement vers une orientation tangentielle à la rotation du mobile, en ce que l'épaisseur des bras va en diminuant et, enfin, en ce que les dents sont constituées par les extrémités des bras.The mobile comprises a rigid central zone (2) provided with a hunting opening (4) and arms (6) extending radially from the central zone (2) to a peripheral zone comprising teeth (8). The arms (6) are flexible to allow small tangential and radial movement of the teeth to absorb shocks. The invention is characterized in that the arms are curved and gradually bend towards an orientation tangential to the rotation of the mobile, in that the thickness of the arms decreases and finally that the teeth are constituted by the ends of the arms.
