Claims

[Claims for Utility Model Registration] In an electric exterior wall blind that transmits power from a motor 10 to a lifting mechanism 7 via a drive device 11, a power transmission path from the drive device 11 to an output shaft 12 to the lifting mechanism 7. A worm 30 and a worm wheel 31 are interposed therein with the worm 30 on the driving side, and the worm 30 and the output shaft 10a of the motor 10 are connected to each other.
A manual operation handle 43 is connectable to the power transmission member 23 between the stop switch 3 and the stop switch 3 for cutting off power supply to the motor 10.
7a is operated, an electric brake unit 38 of a DC dynamic braking type that applies a braking current to the motor 10 is provided in the power supply path of the motor 10.
