PURPOSE: A thermal insulation curtain opening-closing apparatus is provided to reduce the construction time, and to prevent damages to a thermal insulation curtain. CONSTITUTION: A rotary shaft (100) selectively opens a thermal insulation curtain on the upper side of an inner frame (21). A drive motor (200) is located on one side of the rotary shaft to move with the rotary shaft. Plural wires (320) have one ends connected to one end of the rotary shaft, and the other ends connected to the other end of the rotary shaft. A vertical shaft (210) is fixed and combined to one side of the drive motor for preventing the rotation of the drive motor by the rotation of the rotary shaft while operating the drive motor. A first roller (311) is located on both ends of one side of the inner frame along the movement direction of the rotary shaft. A second roller (312) and a third roller (313) are located on both ends of the other side of the inner frame. A first wire (321) is fixed to both sides of the rotary shaft. The second wire (322) is arranged to cross the first wire. |
