As a result, gaps 33 c and 33 d are formed between the standing portions 35, 36 and 37. The end portions of the outdoor louver blade 21 and the indoor louver blade 22 are inserted and held in the gaps 33c and 33d, respectively. That is, a gap 33c is formed between the standing portion 35 and the standing portion 36, and the end portion of the outdoor louver blade 21 is inserted therein. Here, a bottom portion 35a is formed so that the lower end of the standing portion 35 extends to the indoor side, and the lower end surface of the outdoor louver blade 21 can be received, so that the falling is prevented. On the other hand, a gap 33d is formed between the standing portion 36 and the standing portion 37, and the end of the indoor louver blade 22 is inserted therein. Here, a bottom portion 37a is formed so that the lower end of the standing portion 37 extends to the outdoor side, and the lower end surface of the indoor louver blade 22 can be received, so that the falling is prevented.

  As can be seen from FIG. 8, in the standing portion 36, the surface facing the standing portion 35 and the surface facing the standing portion 37 are not parallel and have a predetermined angle. Further, the standing portions 35 and 37 are disposed so as to be substantially parallel to the surface of the standing portion 36 facing the standing portions 35 and 37. Therefore, the outdoor louver blade 21 and the outdoor louver blade 22 inserted and held here are not parallel as shown in FIG.

  Further, a protrusion 36 a as an engaging portion is provided on the inner side surface in the finding direction of the standing portion 36 toward the standing portion 37 side. The protrusion 36 a engages with the engaged portion 24 a formed by the end member 24 of the indoor louver blade 22 described above. As a result, the indoor louver blade 22 and the holder 33 are firmly connected also in the width direction of the louver panel (the direction indicated by VIII in FIG. 8), thereby preventing the louver blade 22 and the holder 33 from coming off. Details will be described later.

  Returning to FIG. 3, the opening / closing mechanism 30 will be described. As can be seen from FIGS. 1 and 3, the operation unit 50 is a member that is fitted and fixed to the piece 18 a of the resin cover 18 and operates the handle by rotating the operation handle 50 a. The interlocking bar 31 can be moved up and down by the operation unit 50, and the louver window 100 can be opened and closed. The power transmission mechanism from the operation unit 50 to the interlocking bar 31 is omitted in the drawing, but a known transmission mechanism can be appropriately selected and used. Further, the position of the operation unit 50 is not limited to the resin cover 18 and may be provided on the resin cover 17 or the resin cover 16.

  The louver window 100 configured as described above is opened and closed by operating as follows. An explanatory diagram is shown in FIG. FIG. 9 is a diagram schematically showing each relationship between the operation of the louver blade 20, the operation of the interlocking bar 31, and the operation of the arm 32. FIG. 9A shows the closed louver window 100, which is gradually opened toward FIGS. 9B to 9E. In order to prevent the figure from becoming complicated, the reference numerals are given only to FIG. 9A, and the reference numerals are omitted from FIG. 9B to FIG. 9E.

The operation unit 50 (see FIG. 3) is operated from the closed posture shown in FIG. Then, the interlocking bar 31 moves downward. Since the end of the holder 33 is rotatably attached to the interlocking bar 31, the end of the holder 33 moves downward following the movement of the interlocking bar 31.
On the other hand, the holder 33 is pivotally fixed to an arm 32 that is pivotally fixed to the vertical frames 13 and 14 at another portion outside the interlocking bar 31. Since the arm 32 is rotatably fixed to the vertical frames 13 and 14, even if the interlocking bar 31 moves downward, it does not move downward.
As a result, the holder 33 and the louver blade 20 fixed thereto are rotated so that the end on the indoor side moves downward while the end on the outdoor side protrudes outward and moves upward. Including. By this operation, the louver window 100 is opened. Here, the above-described operation is smoothly performed because the portion to which each member is fixed is rotatable. When the louver blade 20 is closed, it operates so as to go back from FIG.
Thus, the louver window of this embodiment opens and closes the louver blade 20 in a sliding manner.

  Next, a procedure for individually attaching the outdoor louver blade 21 and the indoor louver blade 22 to the holder 33 of the opening / closing mechanism 30 will be described. 10 to 13 are explanatory diagrams. FIG. 10 is a diagram for explaining the procedure for attaching the outdoor louver blade 21, FIG. 11 is a diagram for explaining the procedure for installing the indoor louver blade, FIG. 12 is a diagram for attaching the outdoor louver blade 21 arranged at the top, and FIG. Reference numeral 13 denotes a procedure for attaching the indoor louver blade 22 arranged at the top. In each figure, the left side of the drawing is the outdoor side, and the right side of the drawing is the indoor side. 10 and 11, the attachment target is the center holder 33 among the holders 33 represented in parallel in the vertical direction. At the time of attachment, the holder 33 is attached to the frame body 10 and can be moved and rotated along the opening / closing operation by the operation unit 50 or the like. Moreover, the worker who performs the installation work is performed from the indoor side.

As can be seen from FIG. 10 (a), the holder 33 is first slightly opened, and the outdoor louver blade 21 is disposed between the target holder 33 and the holder 33 on the holder 33 (FIG. 10 (a)). The position indicated by Xa.). Next, the lower ends at both ends in the width direction of the outdoor louver blade 21 are arranged at the upper end of the gap 33c of the target holder 33 through the holders 33 (positions indicated by Xb in FIG. 10A).
Then, as can be seen from FIG. 10B, the louver blade 21 is inserted into the gap 33 c of the holder 33 as it is.

On the other hand, as can be seen from FIG. 11 (a), the indoor louver blade 22 initially has the holder 33 in a slightly open posture, and the indoor louver blade 22 between the target holder 33 and the holder 33 below it. (Position indicated by XIa in FIG. 11A). Next, the lower ends of both ends in the width direction of the indoor louver blade 22 are arranged at the upper end portion of the gap 33d of the target holder 33 through the holders 33 (positions indicated by XIb in FIG. 11A).
In this state, since the angle of the indoor louver blade 22 does not match the inclination angle of the gap 33d, both ends of the indoor louver blade 22 cannot be inserted into the gap 33d. Further, even if the indoor louver blade 22 is adjusted to the inclination angle of the gap 33 d, both end portions of the indoor super louver 22 are caught on the resin covers 17 and 18 of the frame body 10.
Therefore, by operating the operation unit 50 or the like, as shown by an arrow XIc in FIG. 11B, the inclination angle of the holder 33 is changed to match the inclination angle of the gap 22d with the indoor louver blades 22.
Finally, as can be seen from FIG. 11 (c), the indoor louver blade 22 is inserted into the gap 33 d of the holder 33 as it is.

Moreover, if the indoor side piece 11c which forms the space 11d in the horizontal frame 11 is appropriately inclined, the outdoor louver blade 21 can be guided, so that the workability can be further improved.

On the other hand, the procedure for attaching the indoor louver blade 22 arranged at the top to the holder 33 is as follows.
That is, as can be seen from FIG. 13 (a), the indoor louver blade 22 arranged at the top is first placed with the holder 33 in a slightly open posture, and is arranged below the holder 33 arranged at the top. The indoor louver blade 22 is disposed between the holder 33 and the holder 33 (the position indicated by XIIIa in FIG. 13A). Next, the upper end of the indoor louver blade 22 is inserted into the space 11 d of the horizontal frame 11 so that the indoor louver blade 22 moves from the indoor side with respect to the holder 33. On the other hand, the lower end of the indoor louver blade 22 is disposed on the indoor side of the holder 33 (the position indicated by XIIIb in FIG. 13B).
In this state, the angle of the indoor louver blade 22 does not match the inclination angle of the gap 33d, so that both ends of the indoor louver blade 22 cannot be inserted into the gap 33c. Therefore, by operating the operation unit 50 or the like, as shown by an arrow XIIIc in FIG. 13B, the inclination angle of the holder 33 is changed to match the inclination angle of the gap 22d with the indoor louver blade 22.
Finally, as can be seen from FIG. 13 (c), the indoor louver blade 21 is inserted into the gap 33 d of the holder 33 as it is.

  As can be seen from the above description, in the louver window 100, in the posture in which the upper end portion of the indoor louver blade 22 is disposed in the space 11d of the horizontal frame 11, the indoor louver blade 22 can be rotated even if the holder 33 is slidably rotated.
