Claims

[Claims for Utility Model Registration] (1) A support shaft supported in a cantilever manner on one vertical wall, an electric motor supported in a cantilever manner on the other vertical wall, and the support shaft and the electric motor are rotatable. a winding drum attached to the winding drum, a rewinding spring that is wound around the support shaft and has one end locked to the support shaft and the other end locked to the winding drum, and the unwinding spring facing the electric motor. A rotor fixed in the winding drum, a clutch mechanism for connecting and disconnecting the output shaft of the electric motor and a driven shaft of the rotor, and a clutch mechanism that is compressed and interposed between the rotor and the clutch member to keep the clutch member constantly engaged. An electric type characterized by comprising a clutch spring that presses the clutch member to the joint position, and a release rod that penetrates the other vertical wall and is inserted into the winding drum to separate the clutch member from the output shaft of the drive motor. Shutter opening/closing device. (2) A clutch member in which the clutch mechanism is attached to the output shaft of the electric motor and the driven shaft of the rotor, and a clutch member that is compressed and interposed between the rotor and the clutch member and constantly presses the clutch member to the engaged position. 2. The electric motor according to claim 1, further comprising a clutch spring that penetrates the other vertical wall and is inserted into the winding drum to detach the clutch member from the output shaft of the drive motor. Shutter opening/closing device. (3) The electric shutter opening/closing device according to claim 1, wherein the clutch mechanism is an electromagnetic clutch.
