  The shutter curtain 18 will be described with reference to FIGS.

  The shutter curtain 18 has a structure in which a panel body 25 is connected via a hinge member 26. First, the panel body 25 will be described with reference to FIG.

  The cross section of the panel is substantially flat, a female connecting portion 29 is provided at the upper end of the flat plate portion 27 via a neck portion 28, and a hollow trapezoidal pedestal portion 30 is formed at the lower end portion of the flat plate portion 27. The lower edge portion 27 a extends further downward than the pedestal portion 30.

  The female connecting portion 29 has a cylindrical shape with an oblique upper portion cut out, and a central portion is a cylindrical recess 32. The neck portion 28 forms a step which is retracted from the surface of the flat plate portion 27 by the approximate plate thickness of the lower edge portion 27 a, and the lower leg side 30 a of the pedestal portion 30 has an outer diameter of the female connecting portion 29. It is a concave cylindrical surface having substantially the same diameter.

  The hinge member 26 is made of a synthetic resin, preferably a synthetic resin having wear resistance, such as polycarbonate, polyacetal, polyamide, and the like, and includes a shaft portion 33 and a fixed piece portion 34, and the shaft portion 33 is formed by the cylindrical recess 32. The fixed piece portion 34 is fixed to the pedestal portion 30 with a fixing tool such as a screw.

  The shaft portion 33 is fitted into the female connecting portion 29 of the lower panel body 25, and the fixed piece portion 34 is fixed to the pedestal portion 30 of the upper panel body 25. The hinge members 26 are provided at a required interval in the width direction of the shutter curtain 18, and the upper and lower panel bodies 25 are connected to each other via the hinge members 26 so as to be bent. When the upper and lower panel bodies 25 are in a straight state, the lower edge portion 27a overlaps with the neck portion 28, and the connecting portion of the upper and lower panel bodies 25 is hidden from the outside. The neck portion 28 is provided with a seal member (not shown) that comes into liquid-tight contact with the lower leg side 30a, and the connecting portion is sealed in a straight state of the upper and lower panel bodies 25.

  Of the hinge member 26, the hinge member 26a (see FIG. 6) located at both ends of the shutter curtain 18 has a hollow shaft portion 33a, and the roller shaft 6 is fixed to the shaft portion 33a. (See FIG. 9). Further, the shaft portion 33b of the hinge member 26b (see FIG. 7) provided at a position excluding both ends is solid.
