In this case, the second upper plate 175 is connected by the first upper plate 165 and the fastening bar 150 to be moved together with the first upper plate 165, so that the fourth cam follower 173a is moved. It moves along the fourth long hole 175b.

Next, FIGS. 10C and 11C illustrate a state in which the rotation of the slat 30 starts, and the second cam follower 163a moves along the inclined portion of the second long hole 165b formed in the first upper plate 165. In this case, the first auxiliary plate 163 is moved together along the longitudinal direction of the first long hole 163b by the first cam follower 161a. Thus, the first auxiliary plate 163 in contact with the stop gear 114 is moved in a direction away from the stop gear 114. In addition, when the fourth cam follower 173a is moved along the inclined portion of the fourth long hole 175b formed in the second upper plate 175, the second auxiliary plate 173 is moved by the third cam follower 171a. Is moved along the longitudinal direction of the third long hole (173b). Accordingly, the rack gear 172 spaced apart from the rotary gear 112 by the second auxiliary plate 173 is moved in a direction closer to the rotary gear 112 to be in contact with the rotary gear 112. That is, the first auxiliary plate 163 and the second auxiliary plate 173 move together in directions corresponding to each other according to the movement of the first upper plate 165 and the second upper plate 175.

When the first auxiliary plate 163 is spaced apart from the stop gear 114 and the rack gear 172 installed in the second auxiliary plate 173 is in contact with the rotary gear 112, as shown in FIGS. 10D and 11D. Likewise, the second upper plate 175 is moved along the first upper plate 165 in the longitudinal direction of the rail frame 10 to rotate the rotary gear 112. Therefore, the slat 30 made to rotate together with the rotary gear 112 is rotated at a predetermined angle. The rotation of the slat 30 is selectively rotated 360 ° clockwise or counterclockwise according to the moving direction of the second upper plate 175.

In this case, the length of the fourth long hole 175b formed in the second upper plate 175 is shorter than the length of the second long hole 165b formed in the first upper plate 165. Accordingly, the first upper plate 165 moves the second cam follower 163a along the second long hole 165b, and the second upper plate 175 moves the fourth cam follower 173a to the fourth long hole 175b. It is caught by the end of the) to move with the second auxiliary plate (173). In addition, as the second auxiliary plate 173 moves, the second lower plate 171 moves together by the third cam follower 171a inserted into the third long hole 173b of the second auxiliary plate 173. do. In addition, the second cover plate 177 coupled with the second lower plate 171 is moved together. At this time, as described above, the second cover plate 177 is installed on the rail frame 10 by the third LG guide part LG3 to smoothly move.

On the other hand, the second cover plate 177 and the second lower plate 171 is further provided with a moving means 180 to be easily moved with the second upper plate 175.

More specifically, the support bar 182 is installed in a portion where the second upper plate 175 and the first upper plate 165 are connected by the fastening bar 150. In addition, the moving roller 184 installed on the support bar 182 is provided to be located between the second cover plate 175 and the rail frame 10. Thus, the locking step 177a is formed at a position facing the inner surface of the rail frame 10.

On the other hand, the inclined protrusion 186 is formed in the rail frame 10 facing the locking step 177a so that the moving roller 184 is inserted into the locking step 177a to support the second upper plate 175. do. In more detail, when the second upper plate 175 moves, the moving roller 184 moves together with the second upper plate 175 so that the moving roller 184 stops at the second cover plate 177. When positioned at 177a, the moving roller 184 moves along the inclined surface of the inclined protrusion 186. At this time, the moving roller 184 is in close contact with the locking step (177a) by the inclined protrusion 186. Therefore, the second cover plate 177 in close contact with the second upper plate 175 and the moving roller 184 are moved together.

In addition, the pressing unit 190 is further provided to press the second panel unit 170 through the side of the rail frame 10 (see FIG. 13).

The stick 192 is formed to have a cylindrical shape, and has a tapered shape so that one side thereof is gradually reduced. This is because only a part of the ball 196 accommodated in the stick 192 is exposed to the outside so as not to completely exit. Therefore, the ball 196 is in contact with the side of the second panel portion 170, that is, the second cover plate 177 is pressed. At this time, the groove 177b is formed at a predetermined position of the second cover plate 177 to insert the ball 196 of the pressing unit 190. The predetermined position is to be understood as the position in which the above-described moving roller 184 is inserted into the locking step 177a so that the ball 196 is inserted into the groove 177b when contacting the inclined portion of the inclined protrusion 186. do. The reason for this is to prevent the second cover plate 177 from moving together when the fourth cam follower 173a moves along the inclination of the fourth long hole 175b of the second upper plate 175. In addition, the second cover plate 177 when the fourth cam follower 173a passes along the slope of the fourth long hole 175b and is in contact with the end of the horizontal part to move together with the second upper plate 175. The ball 196 of the pressing unit 190 is spaced apart from the groove 177b by the moving roller 184 inserted into the locking step 177a of the second cover plate 177 to move together.
