It is guided by the third guide wire 15c so as to be slidable, so that it can be lifted and lowered smoothly and easily and reliably.

  Furthermore, since the base portion 25a of the closing piece 25 is fixed to the curing sheet 23a and the tip portion 25b is supported by the third guide wire 15c, the closing piece 25 can be prevented from being beaten by a strong wind.

  Furthermore, since the closing piece 25 is disposed inside the curing sheet, it is possible to suppress strong wind from hitting the closing piece 25 and to prevent the closing piece 25 from being blown by the wind.

  Further, when the curing sheets 23a and 23b are lowered and opened, the entire curing sheets 23a and 23b can be lowered on the lower part of the building 2, for example, on the sheet placing plate 16 shown in the drawing. Compared with the conventional one in which the curing sheet is bundled on the support column, it is possible to improve the appearance at the time of non-working and reduce the obstruction of sunlight.

  Furthermore, since each curing sheet 23a, 23b can be opened and closed individually, the curing sheet can be easily raised or lowered depending on the presence or demand of a resident in the building 2.

  In the above embodiment, the elevating wire 21a is moved up and down by the winch 21 which is the elevating driving means. However, without using the winch, the elevating wire 21a is lifted and lowered by an operator directly by hand. May be.
