11 to 14 are sectional views showing the arrangement relationship of slits in the rotary tube of Fig.

9 to 14, in the roller blind 190, the rotary tube 100 is positioned between the rotation guide 160 and the fixing guide 170 as shown in FIG. 8, the elastic tube 60, the separation tube 70, and the fixed tube 80 are disposed between the rotation guide 160 and the fixed guide 170, Enclose. The rotary pipe (100) has at least one slit (91).

The slit 91 has a circular center C2 in one of the slit end faces (= 100 in Fig. 8 or one of Figs. 11 to 14) of the rotary pipe 100 when positioned at one side wall of the rotary pipe 100, Is formed by being cut at an angle of incidence ([theta]) between 90 DEG and 180 DEG. For a detailed description of the present invention, the rotary tube 100 is shown with a plurality of slits 91 in its side walls. The slits 91 may be formed in the rotary pipe 100 in plurality.

When the four slits 92, 94, 96, 98 positioned sequentially among the slits 91 in the rotary tube 100 are selected, the four slits 92, 94, 96, Is formed by being cut at an angle of incidence 90 DEG to 180 DEG around the center of circle C2 in the slit section of the rotary pipe 100 and is formed along the rotary pipe 100 to the center axis 99 of the rotary pipe 100 ) At the same placement angle.

According to the embodiment of the present invention, the rotary tube 100 preferably has a plurality of slits 91 arranged at an angle of incidence of 120 deg. And an angle of 90 deg. If the cutting angle? Is 180 or more, the rotary tube 100 may be torn around the slit 91 because it is vulnerable to torsional rigidity upon rotation around the fixed tube 80.

When the cutting angle? Is 90 or less, the rotating tube 100 reduces the degree of opening of the slit 91 when rotating around the fixed tube 80, thereby increasing the friction with the fixed tube 80 The rotational operation load can be increased. Therefore, the cutting angle [theta] of the rotary tube 100 can be appropriately adjusted between 90 [deg.] And 180 [deg.] In consideration of the curvature and the length of the fixed tube 80. [

When the plurality of slits 91 are not sequentially rotated about the central axis 99 of the rotary tube 100 at the same angle, the rotary tube 100 is twisted along the length of the fixed tube 80 The rotation speed of the rotary pipe 100 may be different depending on the portion of the rotary pipe 100. Therefore, the arrangement angle can be set to rotate the plurality of slits 91 around the central axis 99 of the rotary tube 100 at the same angle.
