Inside the shutter case, the power supply line extending from the shaft end of the shutter shaft is installed alongside the cover plate when the winding drum is installed inside the shutter case. Since the guide is used, even if the sleeve part for mounting the shutter case is narrow, only the shaft end of the shutter shaft that supports the winding cylinder is placed on the shutter bearing inside the shutter case from above. The winding cylinder can be easily erected in the shutter case with no need to make holes in the brackets that form the side surface of the shutter case, unlike the conventional wiring method for the power supply line for switches. The wiring work can be promptly performed by a simple operation of dropping the power supply line drawn from the shaft end of the shutter shaft into the cover plate from the opened upper part of the shutter bearing.

Since the reinforcing substrate on which the shutter bearing is fixed is detachably attached to the bracket forming the inner surface on one side of the shutter case through the bolts, all the work relating to the erection of the winding drum is performed inside the shutter case. It is also possible to easily perform incidental work such as disassembly and assembly during inspection and maintenance work.

The cover plate is formed integrally by bending a part of the reinforcing substrate vertically and bending the surplus surface in parallel with the reinforcing substrate, and a part of the rising portion from the reinforcing substrate to the cover plate. Since the guide port for the power supply line is opened by cutting out the cover plate, the cover plate can be formed with an extremely simple structure, but the wiring work of the power supply line is facilitated and the power supplied in the shutter case is The power supply line can be reliably protected within the cover plate, and the shutter curtain wound around the installation position of the winding drum does not rub against the slats, preventing breakage and deterioration of the power supply line. can do.

The cover plate is formed separately from the reinforcing substrate, and has a flat surface portion and a supporting surface formed by vertically lowering the peripheral edges of the flat surface portion and bending the extra long edge portions in parallel with the flat surface portion. In addition to being integrally formed with the above, the opening for introducing the power supply line is opened at the falling part from the above flat part to the supporting surface, so even if various electric shutters with different wiring routes are used, Accordingly, the wiring position can be flexibly changed, and complicated wiring bundles can be easily arranged in the cover plate to ensure optimal wiring work.

And so on, which have extremely useful practical effects.
