Abstract

Cette invention concerne un dispositif de changement de vitesse (10), dans lequel la plage de rotation d'un bouton (28) est définie pour être la plage de rotation d'une première saillie de limitation (28A) du bouton (28). Une première barre de verrouillage (54) limite et libère la rotation de la première saille de limitation (28A), limitant et libérant la rotation du bouton (28). Ainsi, la saillie de limitation (28A) peut être utilisée pour limiter et libérer la rotation du bouton (28) de sorte à permettre une configuration simplifiée.
