Claims

[Scope of utility model registration request]

A plurality of panels each of which is connected on both upper sides by a pair of left and right chains that can be moved into an upper panel storage box along a pair of left and right guide rails placed on both sides of the shutter opening/closing opening;
In a shutter device comprising a sprocket for driving a panel in which the chain is engaged within the box, and a support rail that movably suspends the upper part of each panel within the box, the support rail is arranged horizontally. At the same time, the chain allows bending of the chain in a direction along the sprocket, but restricts bending of the chain by a predetermined distance on the support rail side near the sprocket to maintain the chain in a horizontal state. A shutter device in which a part of the chain near the chain connecting portion of each panel is constituted by a push pull chain having a bending regulating portion.
