As disclosed in Japanese Patent Application Laid-Open No. 94943/94, there is known a shutter having a substantially L-shaped shutter body, a cap, and a mounting bracket.

[0003]

Since such a shutter box is long, if the shutter body is made of an extruded shape, rigidity is insufficient. Therefore, a reinforcing cross member such as an angle material is used. The work is troublesome, and the number of parts is large and the cost is high. Also, in the above-mentioned shutter box, screw holes for connecting the shutter body and cap to the mounting bracket are formed integrally with the shutter body, so these screw holes protrude from the inner surface of the shutter body, rotate the drum and extend the shutter. When the shutter stops moving down for some reason during the operation and the shutter is extended around the drum and the diameter becomes large, the shutter may be caught by the screw hole and may be damaged or come off.

Accordingly, an object of the present invention is to provide a shutter box capable of solving the above-mentioned problem.
