The protrusion amount H that protrudes upward from the upper end 33e of the blade plate fixing member 33 of the lower louver 30 is larger than the movement amount L that moves downward after the engagement pin 24 enters. For this reason, when the upper louver 35 is attached, the protruding portion 51 a of the end attachment member 50 of the lower louver 30 functions as a guide for guiding the blade plate fixing member 33 of the upper louver 35. Here, the protruding amount H of the protruding portion 51 a of the end mounting member 50 protruding upward from the blade fixing member 33 of the lower louver 30 is attached to the blade fixing member 33 of the lower louver 30 by the end mounting member 50. This corresponds to the distance from the upper end 33e of the blade fixing member 33 to the upper end 51b of the protruding portion 51a.

  The louver unit 3 mounted in the frame body 2 from the outdoor side in the order of the lower louver 30 and the upper louver 35 has an upper wall portion 34a of the uppermost blade 34 of the upper louver 35 so that the upper frame material of the frame 2 The vertical frame 32 of the lower louver 30 and the upper louver 35 is brought into contact with the vertical frame member 23 of the frame 2 from the vertical frame 32 side. A screw entering toward the vertical frame member 23 is fastened and fixed from the outdoor side.

  According to the louver unit 3 and the gallery door 1 of the present embodiment, the two louvers 30 and 35 arranged side by side have a blade plate fixing member 33 that is arranged side by side and fixes a plurality of blade plates 31. Therefore, it is possible to suppress the bending of the plurality of blades 31 included in each louver 30 and 35 and to align the positions of the blades 31 in the prospective direction. At this time, since the slat plate fixing member 33 is provided on each louver 30, 35, the louvers 30, 35 can be attached and detached individually, and are handled in a smaller size than the integrally formed louver unit. Easy to install and excellent in workability. Also, both the mounting of the lower louver 30 and the upper louver 35 in the frame body and the screwing of the lower louver 30 and the upper louver 35 to the frame body can be performed from the outdoor side. That is, the operator can attach and detach the louver unit 3 only by the work from the outside without moving between the room and the outside, so that the workability is more excellent.

  The lower end 33f of the blade fixing member 33 of the upper louver 35 of the upper and lower louvers 30, 35 is the end attachment member 50 provided at the upper end of the blade fixing member 33 of the lower louver 30.

For this reason, it is possible to regulate the position of the prospective direction of the louvers 30 and 35 positioned above and below, and to improve the workability while regulating the displacement between the louvers 30 and 35 aligned vertically and the deflection of the blade 31. It is possible to provide an excellent louver unit 3.

  Further, after the lower louver 30 is attached to the frame body 2, the upper louver 35 is moved from a position spaced apart from the lower louver 30 in the vertical direction, and is attached in contact with the lower louver 30. At this time, the protruding amount H of the protruding portion 51a from the upper end 33e of the blade plate fixing member 33 is larger than the moving amount L moved in the vertical direction when the upper louver 35 is attached. The distance from the upper louver 35 that is spaced apart in the vertical direction is narrower than the protrusion amount H of the protrusion 51a from the upper end 33e of the blade fixing member 33. For this reason, since the upper louver 35 can be moved along the protruding portion 51a when the upper louver 35 is attached, the positioning of the upper louver 35 is easy, and the louver unit 3 having better workability is provided. It is possible.

  Further, the interval W4 in the communication direction between the portions of the protruding portion 51a and the facing portion 52 facing each other is narrower than twice the distance t2 in the communication direction of the blade plate fixing member 33, so the protruding portion 51a and the facing portion 52, the blade fixing member 33 of the upper louver 35 and the blade fixing member 33 of the lower louver 30 do not shift to a position where they do not face each other in the vertical direction. For this reason, it is possible to reliably prevent the blade plate fixing member 33 of the upper louver 35 and the blade plate fixing member 33 of the lower louver 30 from being displaced in the communication direction.

  Further, the distance W5 in the left-right direction between the connecting portions 53 that connect the protruding portion 51a of the end mounting member 50 and the facing portion 52 is narrower than the distance twice the width W6 in the left-right direction of the blade plate fixing member 33. Between the two connecting portions 53, the blade plate fixing member 33 of the upper louver 35 and the blade plate fixing member 33 of the lower louver 30 do not shift to a position where they do not face each other in the vertical direction. For this reason, it is possible to reliably prevent the blade plate fixing member 33 of the upper louver 35 and the blade plate fixing member 33 of the lower louver 30 from shifting in the left-right direction.

  Thus, the louver unit 3 having the upper louver 35 and the lower louver 30 that are divided and reduced in size is easier to handle and has better workability than the integrated louver unit that covers the entire surface of the opening 2a. . Moreover, even if the louver unit 3 has a configuration in which the louver unit 3 is divided into an upper louver 35 and a lower louver 30, by providing the end attachment member 50, it is possible to prevent the two louvers 30, 35 located above and below from shifting. Is possible. Moreover, the louver door 1 provided with such a louver unit 3 is easy to attach, and the upper and lower louvers 30 and 35 are less likely to be displaced, and the blades 31 are not easily bent. Is possible.

  In the above embodiment, the example in which the end attachment member 50 is attached to the upper end of the blade fixing member 33 included in the lower louver 30 has been described. However, the end attachment member 50 is a blade fixing member included in the upper louver 35. A protrusion 51 a may be provided at the lower end of 33 so as to protrude toward the lower louver 30.
