PURPOSE: An automatic sliding door is provided to reduce noise generated when a door is opened and closed, and users open the door without large power. CONSTITUTION: An automatic sliding door comprises a main bracket(1), first and second rollers(3,4), a pulling force supply device(10), a shock absorber(20), an anti-separation unit(70), and a stopper(80). The main bracket is fixed to the upper part of an inlet, and comprises a rail which guides a roller. The first and second rollers are fixed to the front and rear parts of the door, and open and close the door. The pulling force supply device provides a pulling force to automatically close the door. The shock absorber buffers shock to slowly open and close the door. The anti-separation unit is placed at the front sides of the first and second rollers to prevent the first and second roller from being separated from the rail. The stopper is placed at the rear side of the first roller to stop the door at a desired position. |
