An interlocking chain 13 is suspended between the winding shaft sprocket 11 and the auxiliary sprocket 12 that is fixed in parallel with the winding drum sprocket 6 at one end of the winding drum 5. By driving the motor 7 to rotate forward and backward, the take-up drum 5 and the take-up shaft 9 are interlocked to rotate forward and backward through the drive chain 8 and the interlocking chain 13.

On the other hand, below the floor surface a in the lifting area of the shutter curtain 3,
An underground storage chamber 14 is formed over the entire width of the ascending / descending region, and a traffic regulation body 15 that can move up and down is interlocked in the underground storage chamber 14 in conjunction with the lifting operation of the shutter curtain 3. ing. That is, the wire drum 10a, 1
The tip ends of the suspension wires 16 and 16 having the base end portions attached to 0b are attached to the left and right ends of the passage restrictor 15, and the wire drums 10a and 10b are suspended by the forward and reverse rotations of the winding shaft 9. Wire 16,
The pass-through restricting body 15 moves up and down by winding 16 and rewinding.

Therefore, when the shutter curtain 3 is fully opened, the traffic regulation body 15 is stored in the underground storage chamber 14, and the upper end portion of the traffic regulation body 15 is flush with the floor surface a.
Is set to the highest position, the upper end of the passage restrictor 15 contacts the seat plate 3a of the lowered shutter curtain 3 to close the opening.

Further, the suspension wires 16 and 16 are guided and regulated by the guide portion 18 so as to hold the passage regulation body 15 in the guide rail 17.

In order to open the shutter curtain 3 of the electric shutter 1 in the above-mentioned configuration, FIG.
As shown in (c) to (c), first, the electric motor 7 is started to rotationally drive the winding drum sprocket 6 in the direction of the arrow A, and the shutter curtain 3 is wound up on the winding drum 5 and raised. At this time, the sub sprocket 12 rotates in synchronization with the take-up drum sprocket 6, and the wire drums 10a and 10b are rotationally driven, and the hanging wires 16 and 16 suspended from the wire drums 10a and 10b are paid out. Pass the traffic control unit 15 to the floor a
