In this way, the blind 10 according to the first embodiment can open and close the first louver 1Lv and the second louver 2Lv without being disturbed by the third baton 3Bt arranged in the central portion.

(Structure of moving member)
Next, the configuration of the moving member excluding the slider 2 will be described. Further, since the configurations of the first master carrier 91m and the second master carrier 92m and the first carrier 91c and the second carrier 92c are substantially the same, the moving member excluding the slider 2 is represented by the first master carrier 91m. The configuration will be described below.

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

With reference to FIG. 4 or 7, the rotary transmission mechanism includes a worm W, a worm wheel (not shown), and a transmission sleeve (not shown). The inner circumference 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 shaft Sa.

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

With reference to FIG. 4 or FIG. 7 (A), the transmission sleeve (not shown) can transmit the rotation of the worm wheel to the carrier hook 91f (or carrier hook 92f) which is the suspension axis. The transmission sleeve is fitted between the shaft portion of the carrier hook 91f and the inner circumference of the shaft portion of the worm wheel. When the worm wheel is rotated about an axis, the transmission sleeve can transmit the rotation of the worm wheel to the carrier hook 91f so that the rotation of the worm wheel can be frictionally transmitted.

When the baton of either the first baton 1Bt or the second baton 2Bt is rotated with reference to FIG. 1 or FIG. 2 and FIG. 4, the tilt axis Sa → worm W → worm wheel → transmission sleeve route is followed. The axial rotation 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 shaft is restricted, the frictional transmission of the transmission sleeve does not work, and the shaft portion of the worm wheel idles with respect to the shaft portion of the carrier hook 91f. As a result, the rotation range of the carrier hook 91f is limited to a range of about 180 degrees in the forward and reverse directions.

Referring to FIG. 1 or FIGS. 2 and 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 of the tilt axis Sa around the axis is the carrier hook 91f. It is configured to be transmitted to.

Further, referring to FIG. 4 or FIG. 7B, the first carrier 91c rotatably supports a pair of rollers 9r and 9r at both ends. The pair of rollers 9r and 9r are mounted on a pair of guide rails (not shown) arranged to face the inner wall of the head rail Bh. The roller 9r can roll on the guide rail. 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 a pair of rollers 9r and 9r, the slider 2 holding the first master carrier 91m forms a step on both side surfaces on which a pair of guide rails (not shown) can be slid. (See Fig. 4).

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

Referring to FIGS. 4 to 8, the blind 10 has a carrier moving mechanism for moving the plurality of first carriers 91c and the second carrier 92c arranged inside the head rail Bh.
