  • the present invention is linked to the opening and closing of the rear door of the vehicle cargo compartment, and while the rotating member slides and rotates along the fixed guide member, the roller is operated so that the roller is placed between the rotating member and the fixed guide member at a predetermined designated position, thereby functioning as a stopper to close the door. It is possible to keep it stable in the open state in multi-level positions.

Abstract

Dans la présente invention, un rouleau est actionné pour être suspendu entre un élément rotatif et un élément de guidage fixe à une position prédéterminée tandis que l'élément rotatif tourne de manière coulissante le long de l'élément de guidage fixe en étant relié à l'ouverture/la fermeture d'une porte arrière d'un compartiment de chargement de véhicule, et fonctionne ainsi en tant que butée de façon à maintenir de manière stable la porte dans un état ouvert, ce qui permet une ouverture à étages multiples de la porte arrière de compartiment de chargement au moyen uniquement d'une structure très simple.
