PURPOSE: A sliding door is provided to reduce manufacturing costs and operating noise by linking and opening/closing doors simply and enable easy installation and enhance durability by integrally manufacturing a door frame and a rail. CONSTITUTION: A sliding door comprises a door frame(100), a first coupling member(200), a second coupling member(300), and a sliding member(400). The door frame comprises three guide grooves(110) and a guide rail(120). The guide grooves are formed side by side at intervals in a longitudinal direction. The guide rail is inserted into the guide groove. The first coupling member is installed on the central part of the door frame, and comprises a pair of rollers(210) and a wire(220). The wire is coupled to the rollers. The second coupling member is installed on both sides of the central part of the door frame and is coupled to the wire of the first coupling member by a connecting piece(350). |
