ヤツターの逆巻防止装置。 A transmission gear rotatably driven by a drive means is rotatably supported in a housing fitted with a slat winding shaft at one end, and the rotational torque of the transmission gear in the slat winding direction is transmitted to the housing, and the slat winding shaft of the transmission gear is rotated. In a reverse winding prevention device for a shutter that allows idle rotation relative to the housing in the downward direction, an opening 13 is provided in a part of the housing 10 to expose the transmission gear 7, and the tip of the lock plate 15 is inserted into the opening 13. 15a, and the base end 15b is disposed at a position where it engages with the housing 10 only when the transmission gear 7 rotates in the slat winding direction, and the cover 17 and the lock plate 15 that are fitted around the outer periphery of the housing 10 are connected to each other. A reverse winding prevention device for a shutter, characterized in that a pressure plate 16 compressed between the two presses a lock plate 15 toward a transmission gear 7.
