Abstract

L'invention concerne une serrure à barillet, dans laquelle un rotor ayant une entrée de clé est inséré de façon pivotante dans un cylindre externe, et dans laquelle une rondelle est retenue dans le rotor, la rondelle étant constituée d'un matériau avec une dureté inférieure à une clé mécanique et permettant une commutation entre un état, dans lequel le rotor est en prise avec le cylindre externe, et un état dans lequel le rotor est séparé du cylindre externe en réponse à la clé mécanique insérée dans l'entrée de clé, une rondelle de nettoyage (43) qui est constituée d'un matériau ayant une dureté inférieure à celle de la clé mécanique (11) et qui a une partie de contact coulissant (45) apte à entrer en contact coulissant avec une arête de clé (41) de la clé mécanique (11) étant disposée dans un rotor (13) plus éloigné de l'arrière dans la direction dans laquelle la clé mécanique (11) est insérée dans l'entrée de clé que des rondelles pour amener la partie de contact coulissant (45) à entrer en contact coulissant avec une arête de clé (41) sur la clé mécanique (11) avant que les rondelles n'entrent en contact avec l'arête de clé lorsque la clé mécanique (11) est insérée dans l'entrée de clé. Ainsi, la poussière est empêchée d'entrer dans le côté rondelle même lorsque la poussière adhère à l'arête de clé, et l'usure et le mauvais fonctionnement de rondelle sont empêchés.
