Description of the Related Art Conventionally, in factories and warehouses where vehicles enter and exit, and carry in and carry out articles frequently, so-called sheet shutters, in which a shutter curtain is formed of a flexible sheet material, are provided with features of lightness and lightness. Since the load of the driving force is small, it is often used as a simple partition,
As its structure, a driven shaft in which a plurality of cores having a constant thickness are welded at predetermined intervals in one side portion of a hollow cylindrical winding drum, and the cores are axially mounted at the axial positions of the respective cores. A drive bracket that is pivotally supported by a shutter case or a driven bracket fixed to an opening of a building and that faces the interior of the take-up drum from an open end of the other side of the winding drum. The shutter curtain is wound around the winding drum by the forward / reverse rotation drive of the opening / closing device, and is rewound. The connection structure between the opening / closing device and the winding drum is a winding structure. The output shaft of the switch is directly spline-fitted to a fixed flange coaxially fitted and fixed in the drum.

Since the output shaft becomes large, a bending load is applied to the output shaft at a spline fitting position substantially equal to the rigid connection, and not only a large stress is applied, but also the bearing portion and its peripheral portions are repeatedly rotated by the eccentric output shaft. This also involves a problem that the case material is also deformed or damaged, thereby significantly shortening the life of the switchgear.
