Referring to the operation of the conventional vertical blind configured as described above are as follows.

First, in a state in which the fabric 140 is unfolded, when the operator pulls the fabric distance control code 150 fixed to the carrier 120 in two lines of the fabric distance control codes 150 downward, the carriers 120 are tilted. While being guided by the bar 180, the guide rails 100 are collected in one direction, that is, toward the left end cap 210.

When the operation is carried out as described above, the sunlight transmitted through the window can enter the room and the user in the room can see the outdoor environment.

In the above state, when the operator pulls another fabric distance control code 150 which is not fixed to the carrier 120 in the fabric distance control code 150, the carriers 120 guide the tilt bar 180. While receiving the guide rail 100 is moved in one direction, that is, toward the right end cap 200.

In this case, the carriers 120 are not moved in a state where they are completely collected toward the right end cap 200 while being moved, but are moved while maintaining a constant interval by the aforementioned spacer 190.

Therefore, the fabrics 140 are in a state of covering a window (not shown), that is, a fully expanded state.

When the operation is performed as described above, sunlight transmitted through the window may not enter the room, and the user in the room may not see the outdoor environment.

On the other hand, in the state that the window is covered by the fabric 140 as described above, when the operator pulls any one of the two lines of the fabric angle control chain 160 in the downward direction, the sprocket 230 is rotated in a predetermined direction, As the sprocket 230 rotates, the drive gear 231 of the sprocket 230 rotates the magnetic gear 221 of the cylindrical body 220.

Subsequently, the magnetic gear 221 which receives the rotational force of the driving gear 231 is geared with the gear part 211a formed in the gear hole 211 of the left end cap 210 while rotating.

According to the gear mechanism as described above, since the left end cap 210 is fixed to the guide rail 100, the cylindrical body 220 inside the gear hole 211 of the left end cap 210. It rotates in a predetermined direction.

As the cylindrical body 220 rotates in a predetermined direction as described above, the tilt bar 180 fixed to the cylindrical body 220 also rotates.

Subsequently, as the tilt bar 180 rotates, the worm wheel 125 of the carrier 120 also rotates, and the worm 122 that is given the rotational force of the worm wheel 125 also rotates, and eventually, The angle of the fabric 140 is adjusted.

Here, the reason that the worm wheel 125 rotates as the tilt bar 180 rotates is formed by the tilt-by + -shape, and the inner circumferential surface of the hollow part of the worm wheel 125 is formed by the + -shape. Because.

As described above, by adjusting the angle of the fabric 140, it is possible to control the sunlight transmitted into the room through the window in a state that the window is covered by the fabric (140).

On the other hand, the carrier according to the present invention having the above-described action is to act as follows when adjusting the rotation angle of the fabric (140).

By the way, even if the angle adjustment of the fabric 140 is completed, if the worker continues to pull the fabric angle adjustment chain 160, the tilt bar 180 is to continue to rotate.

Thereafter, as the tilt bar 180 rotates, the worm wheel 125 of the carrier 120 also rotates, and the worm wheel 122 that is given the rotational force of the worm wheel 125 also rotates and the fabric fixture. 123 will also rotate.

Here, since the distal fastener 123 is coupled to the worm 122 in a press-fit state, the locking projection 123c formed in the distal fastener 123 is formed in the first space portion 121a. The fabric fixture 123 is rotated until it is in contact with either end of either end of.

Thereafter, the locking protrusion 123c formed on the fabric fixing device 123 contacts one of both ends of the rotation limiting protrusion 121e formed on the first space portion 121a, and then the tilt bar 180 is continuously rotated. Even if, the fabric fixture 123 is stopped when the locking projection 123c is caught by the rotation limit projection 121e when a predetermined value or more external force is applied to the worm 122 in a press-fit state, but the worm 122 is fitted It rotates about the part 123b.

That is, when the tilt bar 180 is continuously rotated in a predetermined direction, only the worm 122 is rotated around the fitting portion 123b of the fabric fixing device 123.
