The lower limit stop device includes a ratchet wheel 3 attached to one end of the winding shaft 1, and a ratchet wheel 3 that rotates in the unwinding direction of the shutter curtain 5, attached to a bracket 4 that holds one end of the winding shaft 1. The lintel 10 is provided with a pawl 6 that engages with the spring 7 to prevent its rotation, and a spring 7 that biases the pawl 6 in a direction to separate it from the ratchet wheel 3. The wire 1 is moved in the direction of meshing with the ratchet wheel 3 against the biasing force.
A lever 12 towed by the shutter curtain 5 is disposed so as to be perpendicular to one end of the shutter curtain 5, and when the seat plate 13 attached to the lower end of the shutter curtain 5 touches the floor, the lever 12 is pulled by the lever 12. An emergency lower limit stop device for a weight shutter, characterized in that an engaging member 14 is provided which abuts from above against an operating end of the shutter. (2) An emergency lower limit switch 9, which is opened and closed in conjunction with the movement of the pawl 6 and stops driving the motor of the electric switch 2 when the pawl 6 is engaged with the ratchet wheel 3, is attached to the bracket 4. Emergency lower limit stop device for heavy shutters attached to.
