Abstract

L'objectif de la présente invention est de permettre à un arbre d'enroulage de se déplacer dans sa direction axiale lorsque l'arbre d'enroulage tourne et d'améliorer la résistance avec laquelle l'arbre d'enroulage est supporté. Un dispositif store de vitre pour un véhicule est capable de couvrir et d'ouvrir une vitre et comprend : un store de vitre capable de couvrir la vitre; un arbre d'enroulage capable d'enrouler le store de vitre; une paire d'arbres de support pour supporter l'arbre d'enroulage pour que l'arbre d'enroulage puisse tourner et puisse se déplacer dans sa direction axiale; un mécanisme de compression pour comprimer l'arbre d'enroulage dans la direction d'enroulage; et un mécanisme de transmission. Le mécanisme de transmission comporte un élément de transmission à relais qui présente la forme d'un élément long, est disposé le long de la direction axiale de l'arbre d'enroulage, et peut se déplacer conjointement avec l'arbre d'enroulage le long de la direction axiale de l'arbre d'enroulage. Le mécanisme de transmission convertit le mouvement de rotation de l'arbre d'enroulage en mouvement rectiligne dudit arbre et déplace l'arbre d'enroulage dans la direction axiale dudit arbre.
