１項記載のシヤツターの逆巻き防止装置。[Claims for Utility Model Registration] (1) A shutter configured to wind up and unwind slats by installing an endless chain in parallel between the driving sprocket of the opening/closing machine and the driven sprocket of the winding shaft. In the reverse winding prevention device, an actuator of a reverse winding prevention switch that issues a shutter drive stop signal is attached so as to come into contact with the endless chain on the exit side of the driven sprocket that rotates in the unwinding direction of the slat, thereby tensioning the endless chain. A reverse winding prevention device for a shutter, characterized in that the switch is actuated when the switch is biased and pressed in a direction opposite to the biasing direction. (2) In the actuator, a roller that comes into contact with the endless chain is attached to the tip of a sliding rod that is biased to be slidable in the vertical direction by a coil spring, and the rear end of the sliding rod is used to operate the switch. The reverse winding prevention device for a shutter according to claim 1, which is configured to engage and disengage from a child to turn on and off the switch.
