As shown in FIGS. 1 to 7, when actually used, first, the drawstring C in the winding tank channel 22 is pulled, and the drawstring C is pulled out from the wire hole 111 of the base 1, and the drawstring The winding member 2 is rotated by C. Since the first end portion of the first shaft member 3 is fixed in the fixed shaft tank 131 of the base 1, the first shaft member 3 does not rotate, and the winding member 2 becomes the first shaft member 3. When correspondingly rotated, the coil spring 30 is compressed. As shown in FIG. 4, when the winding member 2 rotates, the bump 24 at the other end also rotates with it, and when the bump 24 is displaced on the movement path 62, “when (the drawstring C) is not yet pulled. When the bump 24 is located on the flat portion 621 and the bump 24 located on the flat portion 621 is displaced toward the inclined portion 622, the outer sleeve 6 is rotated counterclockwise, and the cam 641 of the annular protrusion 64 is It is engaged with one side of the bump 51 on the outer periphery of the shaft sleeve 5. As a result, as shown in FIG. 5, the inner shaft sleeve 5 is in a direction opposite to the spiral direction of the first elastic member 43, and the first elastic member 43 is spread and contacts the inner wall surface of the inner shaft sleeve 5. The inner shaft sleeve 5 is restrained by the first elastic member 43 and is not rotated, and the bump 24 is appropriately displaced by the inclined portion 622. Therefore, the outer shaft sleeve 6 is displaced rearward, and the tooth portion 63 is It is meshed with the tooth block 71 of the connection base 7. As a result, as shown in FIG. 6, the second elastic member 44 is compressed by the stopper edge 61, and the bump 24 always contacts the first side 64a of the annular protrusion 64 in the process of pulling the pull cord C. As the outer shaft sleeve 6 continues to rotate, the tooth block 71 is interlocked by the tooth portion 63, the inner shaft tube B continues to rotate by the connection base 7, and the roman shade is controlled as shown in FIG.
