[0129]

[0130] Referring to FIGS. 36 and 37, a shading film (45) can be coupled to a bar (40). The shading film (45) can be wrapped around a second piece (42). The second piece (42) on which the shading film (45) is wrapped can be coupled to the first piece (41), and the shading film (45) can be sandwiched between the first piece (41) and the second piece (42).

[0131] The end of the shade film (45) can be positioned on the lower surface of the lower piece (421) of the second piece (42). The shade film (45) can be fixed when the second part (41b) of the first piece (41) and the lower surface of the lower piece (421) are engaged. When the lower piece (421) and the first part (41b) of the first piece (41) are engaged, the shade film (45) can be inserted into the rib groove (42a) by the fixing rib (41c).

As the tension applied to the shade film (45) changes, the shade film (45) can loosen as it is unwound or wound around the rollers (72, 73). As the upper piece (422) of the bar (40) moves relative to the lower piece (421), it can respond to the change in tension applied to the shade film (45). Accordingly, the shade film (45) can be prevented from loosening as it is wound or unwound around the rollers (72, 73), and the shade film (45) can be kept taut.

[0134] As the tension applied to the shading film (45) increases, the upper piece (422) can move in a direction closer to the lower piece (421) (see FIG. 36). As the tension applied to the shading film (45) decreases, the upper piece (422) can move in a direction away from the lower piece (421) (see FIG. 37). As the upper piece (422) moves while receiving an elastic force with respect to the lower piece (421), it can more effectively respond to changes in the tension applied to the shading film (45).
