A deflection prevention structure of a sliding swing door is provided to make swing motions smoothly by preventing the deflection of the bottom of a sliding swing door by the deadweight when a sliding swing door opens or closes in the swing type. A deflection prevention structure of a sliding swing door, for preventing the deflection of a sliding swing door which is installed to an entrance of a building and opens or closes in the sliding or swing type selectively by a user, comprises a movement frame(100) installed to the lower part of a door hanger(22) of an automatic door to operate together with the movement of the door hanger and provided with a through hole(120) at one end, a rotation member composed of a bolt(210) installed via the through hole of the movement frame and bearings(220a,220b) installed to the outer circumferential surface of the bolt to provide a hinge function to the bolt, a first spacer member(300) installed to the lower part of the movement frame to be movable by the bearing by coupling the bottom of the bolt penetrating the movement frame and provided with many spacer holes(340) penetrating vertically, a second spacer member(400) fixed to the top of an upper frame(610) of a sliding swing door(600) and coupled to the bottom of the first spacer member by fastening screws(332) penetrating screw fastening holes(430) of the first spacer member, and many spacer screws(500) fastened via the spacer holes of the first spacer member and contacted with the top of the second spacer member selectively to control the space between the first spacer member and the second spacer member and to control the deflection angle of the sliding swing door attached with the second spacer member. |
