Claims

[Scope of utility model registration request]

A main body having a ventilation passage formed therein, a rotatable shaft located within the main body, and a shutter attached to the shaft for freely opening and closing the ventilation passage;
One end of the shaft is connected to the output shaft of a drive motor installed outside the ventilation path, and the output shaft is rotated by the drive motor through a clutch that continues when power is cut off to a clutch coil installed inside the drive motor. 1. An electric shutter comprising a switch in parallel with the clutch coil for energizing and disconnecting the drive motor itself, characterized in that the shaft is provided with an elastic member that biases the shutter in a direction to close it.
