防止装置。 A winding rope connected to a hanging pin at the lowest end of the shutter curtain is hoisted up and lowered by a winding drum attached to the upper part of the opening, and the shutter curtain is sent to the ceiling along the guide rail, or In a ceiling storage type shutter that descends from a ceiling to open and close an opening, the lower end of a rope break detection wire fixing fitting is pivotally supported on the hanging pin,
The hoisting rope is inserted into the flat upper end of the metal fitting, and the lower end of the rope is connected to the hanging pin, while a latch is attached to an appropriate position on the side of the shutter curtain and formed at a predetermined pitch along the guide rail. The latch is constantly biased by a spring in the direction of engagement with the latch receiver, and one end of the outer end of the rope break detection wire is fixed to the flat upper end of the rope break detection wire fixing fitting, and the other end of the outer At the same time, one end of the rope break detection wire is fixed to the hoisting rope at a position appropriately above the rope break detection wire fixing fitting, and the other end of the wire is fixed to the latch, and the tension of the hoisting wire is fixed. In this state, the rope break detection wire is tensioned to keep the latch in a position separated from the latch receiver, and when the tension in the hoisting rope disappears, the rope break detection wire is loosened and the latch engages with the latch receiver by the restoring force of the spring. A fall prevention device for a ceiling storage type shutter, characterized in that
