En l'occurrence, une pièce de stockage de ressort (6) reçoit un ressort (3) relativement rotatif par rapport à une platine motrice (5) disposée à l'opposé d'une platine moyeu (5) en connexion avec une platine latérale (51) donnant sur la partie périphérique externe d'un corps principal (50) de platine motrice. Le ressort est disposé entre la platine latérale et le corps principal (50) de platine motrice de façon à empêcher sa chute, une pluralité de protubérances axiales (51g) prenant naissance sur la périphérie extérieure de la platine latérale sont connectées par soudure dans un état de mise en contact avec une pièce en encoche formée sur le bord périphérique externe du corps principal de la platine motrice. En l'occurrence, une réduction du diamètre de l'appareil par réduction de l'espace nécessaire pour la périphérie externe du ressort devient compatible avec une transmission d'un couple élevé, et également, une rigidité de connexion élevée peut être obtenue de façon à empêcher le ressort de retomber afin d'augmenter la fiabilité du dispositif.
