A winding shaft is provided around the drive shaft to cover the drive shaft and suspend and support the screen. The winding shaft is integrally rotatable with a shaft support member and is rotatable with respect to the shaft support member. The material is supported so as to be movable in the axial direction of the winding shaft. Therefore, the bending is suppressed and the bending of the drive shaft is not transmitted to the winding shaft.

分は同一番号を付してその説明を省略する。[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The same components as those in the conventional example are denoted by the same reference numerals, and description thereof is omitted.

れるピン９により相対回転不能に嵌着されている。As shown in FIG. 1, a drive shaft 4 is rotatably supported between a pair of support brackets 2, and the drive shaft 4 is driven to rotate by a motor (not shown). A drive ring 5 as a shaft support member is fitted to the drive shaft 4 at two places. The drive ring 5 is fitted to a drive shaft 4 having a total length of 5 meters, for example, at a position 1 meter from each end from both ends.
As shown in the figure, a pin 9 engaged between the drive shaft 4 and the drive ring 5 is fitted so as not to rotate relatively.
駆動リング５の外周には巻取軸７が嵌着されている。

ている。A winding shaft 7 is fitted on the outer periphery of the drive ring 5.
That is, the take-up shaft 7 is formed to have the same length as the drive shaft 4, and four projecting ridges 8 are formed on the inner peripheral surface thereof at equal intervals in the longitudinal direction of the take-up shaft 7. The surface is provided with a concave ridge 9 which engages with the ridge 8. And ridge 8
And the ridge 9 are engaged with each other, and the winding shaft 7 and the drive ring 5
Is fitted so as to be movable in the axial direction and not to rotate relatively. The screen 3 is suspended from the winding shaft 7.

る。Now, in the roll blind configured as described above, when the motor operates and the drive shaft 4 is rotated, the drive shaft 4 and the winding shaft 7 are integrally rotated via the drive ring 5,
The screen 3 is raised and lowered. At this time, since the take-up shaft 7 is supported by the drive shaft 4 at two intermediate portions thereof, the bending of the take-up shaft 7 in this state is smaller than when the take-up shaft 7 is supported at both ends. Significantly smaller. The drive shaft 4 whose both ends are supported by the support bracket 2 is bent due to its own weight and the weight of the take-up shaft 7 acting via the drive ring 5. Since it is supported only at the point, the bending of the drive shaft 4 is not transmitted to the winding shaft 7. Since the winding shaft 7 is supported so as to be able to move relative to the driving ring 5 in the axial direction,
The mismatch in the amount of deflection between the drive shaft 4 and the winding shaft 7 is absorbed by the axial displacement of the winding shaft 7 with respect to the drive ring 5.
従って、このロールブラインドでは巻取軸７の撓みを
大幅に抑制してスクリーン３の皺の発生を未然に防止す
ることができる。Therefore, in this roll blind, the bending of the winding shaft 7 can be largely suppressed, and the wrinkles of the screen 3 can be prevented from occurring.
