As shown in FIG. 2 and FIG. 3, the louver unit 70 is configured such that the flat plate portion 70f of the second blade 70B is in contact with the surface on the outdoor side of the portions constituting the mesh receiving recesses 11g and 12g, respectively, and the auxiliary ventilation passage 74 is close to the left The posture of the vertical frame 12 is fixed to the frame body 10 via a connecting bracket 84 provided at the vertical frame base portions 11 a and 12 a. As can be seen from the figure, when the external panel 20 is closed, the louver unit 70 fixed to the housing 10 is in a state where a portion thereof located on the outdoor side is housed inside the reinforcing fin portion 20b.

In the ventilation device 100 configured as described above, when the inner panel 30 is closed, as shown in FIG. 2, since the compact member 34 and the watertight member 33 are present between the inner panel 30 and the frame 10, There will be strong wind outside, and no outdoor air or rainwater will enter the room. In addition, when the inner panel 30 is closed, the outer panel 20 is also closed. Therefore, it is possible to eliminate protrusions to the outside when not needed.

On the other hand, as shown in FIG. 3, when the inner panel 30 is opened to the indoor side, the slider 50 is moved by the inner connecting member 52 and the outer panel 20 is linked by the outer connecting member 53, so the outer panel 20 will open to the outdoor side. Thereby, since the external panel 20 protruding to the outside functions as a wind deflector, even when the external wind direction is along the surface of the housing 10, outdoor air can be efficiently introduced into the room. At this time, since the movement of the slider 50 is restricted by the blocking block 51, it is possible to prevent the external panel 20 and the internal panel 30 from being opened more than necessary. In addition, the slider 50 that is in contact with the blocking block 51 is restricted from moving in a direction away from the blocking block 51 due to the engagement of the engaging member 57. Therefore, even when the hand is separated from the inner panel 30, the state where the outer panel 20 and the inner panel 30 are continuously opened can be maintained.

Moreover, since the louver unit is disposed at a position on the indoor side than the external panel 20, it does not cause rainwater to enter the room when it rains. That is, in the louver unit 70, since the ventilation passage 73 and the auxiliary ventilation passage 74 have the reverse passage portions 73a and 74a, respectively, they can be used outdoors. When the passing air passes, it efficiently captures rainwater and other water. In addition, since the air inlet 71 is provided close to the right vertical frame 11 with respect to the air outlet 72 in the ventilation passage 73, the outdoor air introduced from the left to the right by the external panel 20 will flow from the right to the right in the ventilation passage 73. Flowing on the left. Therefore, it is possible to more reliably capture water such as rainwater in synergy with the effects of the above-mentioned reverse passage portions 73a, 74a. The water trapped in the ventilation passage 73 and the auxiliary ventilation passage 74 is discharged to the outside of the shutter unit 70 from the open lower end, and therefore does not enter the room. In addition, since a cover plate 82 is provided at a position located at the upper end of the shutter unit 70 so as to cover the upper ends of the ventilation passage 73 and the auxiliary ventilation passage 74, even if water such as rainwater is immersed from the upper gap generated when the external panel 20 is opened It will not enter the room.

Therefore, since the internal panel 30 and the mesh body 40 only need to be configured with the internal opening 10A as an object, the external dimensions can be set small. In addition, the external connection member 53 connecting the slider 50 and the external panel 20 is passed through the slits 13m and 14m provided in the fin-shaped projections 13d and 14d. A bristle-like member 60 is attached to a portion located on the outdoor side with respect to the slits 13m and 14m penetrated by the external connection member 53. Thereby, the slider 50 can be arranged in the main body with respect to the inner panel 30 and the mesh body 40 inside the housing 10. The viewing direction coincides, and the external panel 20 can be opened and closed without incurring an increase in the depth dimension, so that the ventilation efficiency can be improved and foreign matter can be prevented from entering.

In addition, since the louver unit 70 may be configured with the internal opening 10A of the frame body 10 as an object, it can be disposed inside the frame body 10 without interfering with the external connection member 53. In addition, since the slider 50 is arranged to move closer to the indoor side than the center that bisects the depth dimension of the upper frame 13 and the lower frame 14, it is possible to secure space in a portion located outside the slider 50 and enable The louver unit 70 is housed without increasing the size of the front view of the housing 10.

Moreover, in the said embodiment, although the ventilation device 100 which formed the horizontal connection window with the FIX window 1 was illustrated, you may attach it to the door and window other than a FIX window in the form of a horizontal connection window or a vertical connection window. In addition, although the size of the ventilation device 100 along the left-right direction is set to be equivalent to 1/8 of the doors and windows, this size is for illustration only, and does not necessarily need to be this size. Furthermore, although the ventilator 100 which is opened and closed in conjunction with the outer panel 20 and the inner panel 30 is exemplified, the inner panel does not necessarily need to be provided, and the outer panel does not necessarily need to be able to be opened and closed.

In addition, in the above-mentioned embodiment, the blades 70A, 70B, and 70C and the connection member 80 are formed as separate members, and the connection member 80 is provided with a screw hole 80g for holding the cover plate 82. Therefore, if the blades 70A, 70B, and 70C are formed by extruding a profile, and 80 g of screw holes are directly provided on the blades 70A, Compared with the cases of 70B and 70C, it is possible to suppress the case where the cross-sectional area of the ventilation passage 73 is reduced. However, the present invention is not limited to this, and a screw hole may be directly provided on the blade. In addition, since the auxiliary ventilation passage 74 is provided in the louver unit 70, the amount of air passing through the louver unit 70 can be increased, and the ventilation efficiency can be improved. In addition, in the auxiliary ventilation passage 74, since the air inlet 71 is opposed to the depth surface 12b of the left vertical frame 12, and a reverse passage portion 74a is provided on the way, the water from outside does not easily enter the room. However, in the present invention, it is not necessary to provide an auxiliary ventilation passage in the shutter unit.
