The present invention relates to a sliding automatic door sealing unit moved to be slid in both directions from an inner side of a door frame, and blocks inflows of dust from a gap between doors and gaps of a left and a right side of the door frame, and various noises or wind when the doors, which open and close an entrance, shield the entrance. More specifically, the sliding door sealing unit, comprises: a fixing frame (110) vertically installed and fixated on a roller (3) moved along a rail (4) of a door frame (1) in both directions, forming a plurality of first holes (111) in a longitudinal direction at regular intervals; a supporting frame (120) horizontally arranged on a lower part of the fixing frame to be able to rotate, forming a plurality of second holes (121) in a longitudinal direction at regular intervals wherein a door (2a) is installed in a bottom to be able to rotate; a buffering spring (130) which supports the supporting frame by consistently pulling the supporting frame; a connecting member (140) fixated to an inner side between the fixing frame and the supporting frame by a bolt, integrally connecting the fixing frame and the supporting frame to be able to rotate; a rotary movement element (150) fixated to one outer surface side of the supporting frame by a bolt, allowing the door bend at a predetermined angle by rotating the supporting frame downwards; and a latching member (160) arranged on the door frame in a fixated state, fixating the rotary movement element by rotating the rotary movement element. |
