Abstract

L'invention concerne : un miroir de cabine de véhicule qui présente une durabilité élevée et qui peut maintenir son aspect et ses performances de réflexion de la lumière sur une longue période ; et un dispositif de miroir de cabine de véhicule. Un miroir de cabine de véhicule (10) est supporté à sa périphérie par un élément de cadre (20), et peut être commuté entre un état d'utilisation dans lequel une surface de miroir (10a) est visible et un état de non utilisation dans lequel la surface de miroir (10a) n'est pas visible. Le miroir de cabine de véhicule comprend : une feuille de verre (10A) qui comporte une première surface (11), qui est la surface du miroir (10a), et une seconde surface (12) sur le côté en regard de la première surface (11), et qui possède une couche réfléchissant la lumière (10C) disposée sur la seconde surface (12) ; et une couche antisalissure (10B) qui recouvre au moins une partie de la première surface (11).
