When the tilting electric motor 97 is operated from this state and the output rotating shaft main body 114 is rotated in the B direction, the rotating member main body 111 is also rotated in the B direction, and the connecting mechanism 75 is raised with respect to the connecting mechanism 76. When the rotary member main body 111 is rotated to the maximum in the A direction by the further operation of the electric motor 97 for tilting, the louver 7 is moved from the front edge 22 of the plate-shaped main body 31 to the rear as shown in FIGS. It is tilted so that the edge 24 coincides with the horizontal direction. As shown in FIGS. 14 to 16, when the louver 7 is tilted, the operation of the tilting electric motor 97 is stopped.

  After the operation of the tilting electric motor 97 is stopped, when the lifting electric motor 130 is operated and the rotary shaft 139 is rotated in the F direction synchronously, the chain 124 is moved in the D direction synchronously. Ascending occurs and the coupling mechanisms 75 and 76 begin to fold from below. When the movable table 128 is moved up to the highest level by the further operation of the lifting electric motor 130, the louvers 7 are stacked on top of each other as shown in FIGS. As a result of being raised, the opening 6 is opened.

  By operating the tilting electric motor 97 and the lifting electric motor 130 in the opposite directions, the louver 7 is changed from the state shown in FIGS. 17 to 18 to the state shown in FIGS. 16 to the state shown in FIG. 1 and FIG. 9 to FIG. 13 can be lowered, raised and tilted, respectively.

  As described above, in the louver device 1 of this example, the louver 7 includes the blade member 11 and the pair of support members 14 and 15 that support the both ends 12 and 13 of the blade member 11. At least one of the members 14 and 15, in this example, each of the support members 14 and 15, is a support body so that the support body 21 and the front edge 22 of the blade member 11 can be inserted and removed in the lateral direction X. The front edge holding portion 23 that is formed on the front edge 22 side of the blade 21 and holds the front edge 22 of the inserted blade member 11 in the vertical direction V, and the rear edge 24 of the blade member 11 can be inserted and removed in the lateral direction X. A rear edge holding part 25 that holds the rear edge 24 of the blade member 11 that is formed on and inserted into the rear edge 24 of the support body 21 in the vertical direction V and a front edge holding part in the front-rear direction X. 23 and The support member 21 is disposed at a portion 26 of the support main body 21 between the edge holding portion 25 and a locking portion 27 that locks the blade member 11 in the lateral direction X at the portion 26. The plate-like main body 31 extending in the lateral direction X and the end portions 12 and 13 of the plate-like main body 31 are formed so as to be inserted and held in the respective front edge holding portions 23 of the support members 14 and 15. The rear edge formed on the end portions 12 and 13 of the plate-like main body 31 so as to be inserted and held in the front edge held portion 33 and the rear edge holding portion 25 of each of the support members 14 and 15. It is arranged at a portion 36 of the plate-like main body 31 between the edge holding portion 35 and the front edge holding portion 33 and the rear edge holding portion 35 with respect to the front-rear direction Y. And a locked portion 37 to be locked The plate-like main body 31 is separated from the front edge held portion 33 and the rear portion so that the locked portion 37 can be released from the locked portion 27 and the locked portion 37 can be unlocked by the locked portion 27. The bent portion 35 is bent while approaching in the front-rear direction Y, while the bent portion 37 is bent so that the locked portion 37 can be locked by the locking portion 27. Therefore, it is possible to easily attach and remove the support members 14 and 15 to and from the blade member 11, and use bolts or the like for attaching the support members 14 and 15 to the blade member 11. Parts can also be eliminated.
