Abstract

Dans un dispositif de changement de vitesse (10), un engrenage rotatif (18) d'un levier (14) est maintenu sur une glissière d'arrêt (20), et le levier (14) est maintenu dans une position de changement de vitesse. Lorsqu'un mécanisme d'entraînement (34) amène le levier (14) à pivoter au moyen de la glissière d'arrêt (20) et de l'engrenage rotatif (18), une butée (46) limite le mouvement de la glissière d'arrêt (20), limitant ainsi la libération du maintien de l'engrenage rotatif (18) sur la glissière d'arrêt (20). Grâce à cette configuration, le maintien de l'engrenage rotatif (18) sur la glissière d'arrêt (20) peut être maintenu de manière appropriée.
