A swing door is provided to reduce load applied to a rotating unit and a hinge unit by using a door made of double panels of an SUS(Steel Use Stainless) group and reinforcing cores of paper material. A swing door comprises a door(2), a packing holder(3), a rotating unit(4), a hinge unit(6), a packing(8), and brackets(10). The door is provided with grooves(2a) at two lateral ends and a reinforcing core(2b) therein. The packing holder fits into the grooves of the door and is provided with a packing guide groove(3a) at one side end. The rotating unit is installed at the bottom part of a door frame, and rotates and supports the door. The hinge unit is installed at the top of the door frame and serves as a rotary shaft, when the door rotates. The packing fits to the packing guide groove of the packing holder, and prevents objects which are held between the doors from breaking. The brackets are installed at the top and bottom of the door and fix the rotating unit and hinge unit. |
