PURPOSE: To reduce cost for the execution of works and running cost as well by providing the motor driver shutter with a battery feeding drive current to an electric motor, and with a solar cell for charging the battery.

CONSTITUTION: The shutter curtain 1 of the motor-driven shutter is firmly installed on the window of a dwelling house, as an electric motor is driven normally and/or reversely, the window is opened in an open posture where the shutter is taken up so as to be housed in a shutter case 3, and is closed in a close posture where the shutter hangs down along paired right and left guide rails 4. Next, a solar cell 6 is installed on the upper surface section of a case 3 projected in a hood shape out of a window upper section, and a battery 5 is internally packaged in the intermediate section of the guide rail 4, so that an electric motor 2 is driven by current fed from the battery having been charged by the cell 6. By this consitution, the formation of a shutter unit independent from the view point of a power supply with no AC power supply pulled out of the building side permits both cost for the execution of works and running cost to be ruduced.
