<P>PROBLEM TO BE SOLVED: To provide a renovated motor-driven shutter device for avoiding the event that a shutter curtain structural member as part of a shutter curtain, when wound on a motor-driven winding shaft while being shifted in the horizontal direction, interferes with an intermediate structural body connecting a supporting bracket for the motor-driven winding shaft to an electric motor. <P>SOLUTION: A winding shaft as a manual winding shaft is renovated into the motor-driven winding shaft 20 which is rotated by the driving force of the electric motor stored inside, while leaving the supporting bracket 8 supporting the manual winding shaft and a bearing part 10 provided on the bracket 8. The bracket 8 and an opening/closing device 21 using the electric motor as a structural element are connected to each other via the intermediate structural body 30 whose size D1 in the diameter direction of the winding shaft 20 is smaller than a diameter size D2 of the winding shaft 20, and the intermediate structural body 30 falls within an extending diameter size extending the diameter size D2 to the side of the bracket 8. <P>COPYRIGHT: (C)2012,JPO&INPIT |
