And the cap 25 is fitted to the end of the weight bar 23.

Then, as shown in FIG. 5, the cylindrical portion 22 into which the stopper bar 26 is inserted is locked in the opening groove 24, and the weight bar 23 is suspended and supported by the screen 20. The end bar 20 a of the covering portion 21 is also locked in the opening groove 24 by the stopper bar 26, so that the weight bar 23 is covered by the covering portion 21. In this way, by covering the weight bar 23 with the covering portion 21 having a pattern substantially continuous with the pattern of the screen 20, a large deviation between the pattern of the screen 20 and the pattern of the weight bar 23 is prevented.

[0010]

In the above-described weight bar mounting device, the cylindrical portion 22 into which the stopper bar 26 is to be inserted must be formed by sewing in advance, so that the assembling work is complicated. Further, as shown in FIG. 5, the covering portion 21 is held in a state where the stopper rod 26 is in contact with the opening of the opening groove 24.
Is attached to the outer peripheral surface of the weight bar 23, so that it is difficult to insert the end 20a of the covering portion 21 into the opening groove 24 with the retaining bar 26 inserted. Therefore, the end 20
