Abstract

L'invention concerne un dispositif de changement de vitesse configuré de telle sorte qu'un corps de clic communique avec un bouton par l'intermédiaire d'une clé, et qu'un ressort de clic pousse le bouton vers un côté de position de changement de vitesse par l'intermédiaire du corps de clic et de la clé. Suite à l'actionnement d'un mécanisme de fonctionnement, une projection d'actionnement d'une came de rotor libère la communication du bouton et du corps de clic qui est réalisée par l'intermédiaire de la clé, et le bouton est mis en rotation. Grâce à cette configuration, la force d'actionnement du mécanisme de fonctionnement peut être maintenue petite.
