May be connected and used in accordance with the roof dimension of the container house 1.

  In this embodiment, the shaft fixing portion 30 and the base portion 20 are formed separately, but the shaft fixing portion 30 (the main body portion 30A) and the base portion 20 are integrally formed. Tools may be used.

  On the other hand, the heat shield sheet 10 is made of a synthetic resin sheet that has flexibility and stretchability and reflects solar heat, solar rays, and the like. For example, as shown in the present embodiment, the heat shield sheet 10 reflects solar heat, solar rays, and the like. A woven fabric sheet formed by knitting a resin yarn material colored in silver or the like vertically and horizontally can be suitably used.

  The heat shield sheet 10 is fixed to a shaft 3 fixed on the roof, and is stretched between the shafts 3 and 3 installed on both ends of the container house 1 (see FIG. 4). In the present embodiment, a heat shield sheet 10 that is long in a band shape in a direction orthogonal to the trunk portion of the shaft 3 is used. In addition, as shown in FIGS. 2 and 3, the heat shield sheet 10 used in the present embodiment is knitted with vertical and horizontal resin yarn materials at portions other than both ends and the center in the width direction (portions indicated by cross hatching). Although the eyes are clogged, the both ends and the center do not fix the resin yarn material (weft yarn 10a) with the warp yarn 10b (see an enlarged partial plan view surrounded by a one-dot chain line in FIG. 4). This central portion constitutes an insertion portion 11 through which a shaft portion of the bolt can be inserted.
