(Configuration of moving parts)
Next, the configuration of the moving members excluding the slider 2 will be explained. Furthermore, since the configurations of the first master carrier 91m, the second master carrier 92m, the first carrier 91c, and the second carrier 92c are substantially the same, the first master carrier 91m is representative of the moving members excluding the slider 2. The configuration will be explained below.

Referring to FIG. 4 or FIG. 7(B), the tilt axis Sa has a plurality of spline grooves extending in the axial direction formed on the outer periphery. The first master carrier 91m includes a rotational force transmission mechanism therein. When the rotational force transmission mechanism is driven, the first louver 1Lv and the second louver 2Lv can be rotated forward or reversed around the vertical axis.

Referring to FIG. 4 or 7, the rotational transmission mechanism includes a worm W, a worm wheel (not shown), and a transmission sleeve (not shown). The inner periphery of the worm W is slidably connected to the tilt axis Sa. Further, the inner circumference of the worm W meshes with the outer circumference of the tilt axis Sa.

Referring to FIG. 4 or 7, a worm wheel (not shown) meshes with the worm W. The worm wheel can convert rotation of the worm W around the horizontal axis into rotation around the vertical axis. In this way, the worm W and the worm wheel constitute a "worm gear" in which the extending directions of a set of gear shafts are different from each other.

Referring to FIG. 4 or FIG. 7(A), a transmission sleeve (not shown) can transmit the rotation of the worm wheel to the carrier hook 91f (or carrier hook 92f) serving as a hanging shaft. The transmission sleeve is fitted between the shaft of the carrier hook 91f and the inner periphery of the shaft of the worm wheel. When the worm wheel is rotated around the axis, the transmission sleeve can frictionally transmit the rotation of the worm wheel to the carrier hook 91f.

Referring to FIG. 1 or FIG. 2 and FIG. 4, when either the first baton 1Bt or the second baton 2Bt is rotated, it passes through the path of tilt axis Sa → worm W → worm wheel → transmission sleeve. Rotation around the axis of either the first baton 1Bt or the second baton 2Bt can be transmitted to the carrier hook 91f. On the other hand, when the rotation of the carrier hook 91f around the axis is restricted, the frictional transmission of the transmission sleeve ceases to act, and the shaft of the worm wheel idles relative to the shaft of the carrier hook 91f. As a result, the rotation range of the carrier hook 91f is limited to approximately 180 degrees in forward and reverse directions.

Referring to FIG. 1, FIG. 2, and FIG. 7, the first master carrier 91m is guided by the tilt axis Sa and is allowed to move in the axial direction, but the rotation around the tilt axis Sa is caused by the carrier hook 91f. It is configured to transmit power to the

Further, referring to FIG. 4 or FIG. 7(B), the first carrier 91c rotatably supports a pair of rollers 9r and 9r at both ends. The pair of rollers 9r and 9r are placed on a pair of guide rails (not shown) that are arranged to face each other on the inner wall of the head rail Bh. The roller 9r can roll on the guide rail. Note that the second master carrier 92m and the second carrier 92c are also provided with a pair of rollers 9r and 9r. Although the first master carrier 91m is not provided with the pair of rollers 9r and 9r, steps are formed on both sides of the slider 2 holding the first master carrier 91m so that the slider 2 can slide on a pair of guide rails (not shown). (See Figure 4).

Further, referring to FIG. 4 or FIG. 7(B), the first master carrier 91m and the plurality of first carriers 91c have a pair of holes at their lower portions through which the looped drive cord 921 can be freely inserted. Further, the plurality of second carriers 92c have a pair of holes opened at their lower portions through which the looped drive cord 921 can be freely inserted. The second master carrier 92m has one hole at the bottom through which one of the looped drive cords 921 can be freely inserted, but the other hole opened at the bottom of the second master carrier 92m has the looped drive cord 921 forms a second connecting portion 92j to which the other end is moored (see FIG. 3(B)).

Referring to FIGS. 4 to 8, the blind 10 has a carrier moving mechanism that moves the plurality of first carriers 91c and second carriers 92c arranged inside the head rail Bh. The carrier moving mechanism includes a plurality of flexible first spacer links 1Ls and second spacer links 2Ls (see FIG. 3), which will be described later.

(Configuration of first spacer link)
Next, the configuration of the first spacer link 1Ls according to the first embodiment will be described. Referring to FIGS. 4 to 8, the first master carrier 91m and the plurality of first carriers 91c are interconnected by a strip-shaped first spacer link 1Ls.

Referring to FIGS. 4 to 8, one end of one first spacer link 1Ls is fixed to a first carrier 91c that is movably connected to the first operation unit 91u, and the other first spacer link 1Ls One end portion is fixed to the upper surface of each other first carrier 91c. The other end side of the first spacer link 1Ls can slide on the upper surface of the adjacent first spacer link 1Ls. Furthermore, an engagement piece 1Es is protruded upward from the tip of the other end of the first spacer link 1Ls (see FIG. 4(B)).
