Claims

[Scope of Claim for Utility Model Registration] 1. An opening rail facing vertically arranged on the left and right edges of the opening, a ceiling rail arranged on the ceiling on the indoor side, and an opening to connect both rails. A roughly inverted L-shaped guide rail having a rail curved portion curved in a roughly R shape at the upper part is provided, and a guide roller rolling on the guide rail bendably connects panels attached to both left and right edges. The shutter curtain is equipped with an actuation chain or an actuation belt whose tip end is connected to the lowermost panel of the shutter curtain, and the actuation chain or actuation belt is suspended, and the actuation chain or actuation belt is suspended based on the drive of the opening/closing machine. The shutter curtain is equipped with a sprocket that rotates around a support shaft in the left and right direction in order to open and close the shutter curtain by winding up and lowering the shutter curtain. The indoor side is the side that is connected to the lowest end panel, and the outdoor side is the side that is fed out from the sprocket when the shutter curtain is opened, and the operating chain or actuation on the side that is fed out from the sprocket is set so that An electric overhead door characterized in that the belt is configured to be on the outdoor side with respect to the operating chain or the operating belt connected to the lowest end panel. 2. In the first aspect, the shutter curtain further includes a guide for accommodating an operating chain or an operating belt that is rolled up and let out from the sprocket in order to open the shutter curtain, and the guide is arranged to accommodate an operating chain or an actuating belt that is let out from the sprocket and hangs down. An electrically operated overhead door characterized in that the electric overhead door is arranged vertically at a position closer to the outdoors than the operating chain or operating belt connected to the lowest end panel so that the operating chain or operating belt is stored therein.
