PURPOSE:To enable a panel to run by both electrically and manually operating methods by mounting a motor and an electromagnetic clutch, interposed halfway of a transmission route of rotation of the motor, onto a runner protruded above the panel. CONSTITUTION:A runner 3, having running wheels 2, 2, is protruded to the upper of a panel 1, and a motor 4 and an electromagnetic clutch 5, interposed on the halfway of a transmission route for transmitting rotation of the motor 4 to the running wheels 2, 2, are mounted to the runner 3. The running wheels 2, 2 are drive-rotated to perform electrically-operated running of the panel 1 by transmitting rotation of the motor 4 to the runner 3 through the electromagnetic clutch 5. Rotation of the running wheels 2, 2 is made free by automatically disconnecting the electromagnetic clutch 5 when power is interrupted, and the panel 1 is made possible to run by manual operation. |
