Claims (1)

[Scope of Claim for Utility Model Registration] (1) An upper rail body having a guide groove and guide rails on the inner and outer sides of the guide groove, and an upper rail body movably suspended on the upper rail body via a plurality of guide rollers. A plurality of shutter bodies that are foldably connected via hinges, and a pivot shaft that rotatably supports the shutter bodies and is interposed between one end of the shutter bodies and one end of the upper rail body. The rotation center shaft is selectively attached to either the right upper part or the outer upper part of one end of the shutter body, and the plurality of guide rollers are attached to the inner guide rail or the inner and outer parts. A shutter opening/closing device characterized by selectively engaging one of the guide rails in a staggered manner. (2) The storm door opening/closing device according to claim 1, wherein the rotation center shaft is elastically supported by the case body via a coil spring so as to be able to move up and down. (3) The plurality of guide rollers are rotatably supported via a rotating frame that is supported horizontally rotatably on a suspension support rod, and the suspension support rod is attached to a mounting frame that is attached to the shutter body. The shutter opening/closing according to claim 1 or 2 of the utility model registration claim, characterized in that a roller that is fixed and engages with a guide groove of the upper rail body is rotatably mounted on an axis. Device. (4) Utility model registration claim 1, characterized in that the upper rail body has a branch guide groove communicating with the guide groove at one end and a branch guide rail communicating with the inner and outer guide rails. The shutter opening/closing device according to any one of Items 1 to 3.
