装置。[Scope of Claim for Utility Model Registration] (1) A motor shaft and a planetary gear reduction mechanism are installed on the drive shaft of the louver winding and lowering shaft rotatably attached to the gear case so that the spur gear and transmission fitting can be rotated as one unit. An operation shaft is attached to the gear case so as to be able to rotate and move in the axial direction, and is attached to the gear case so as to be able to rotate and move in the axial direction. A coil spring is externally mounted on a guide fitting fixed to the guide fitting, so that the coil spring can expand in diameter and move away from the guide fitting by rotation of the transmission fitting, and can be brought into close contact with the guide fitting by contracting in diameter by rotation of the transmission fitting, An automatic opening/closing device for a shutter, etc., in which both ends of the coil spring are supported by the transmission fitting and the fixing fitting, respectively. (2) An automatic opening/closing device for a shutter or the like as set forth in claim 1 of the utility model registration claim, in which the operating shaft is biased and held in a non-meshing position with the spur gear by an interposed spring.
