The passage 74 is fixed to the frame body 10 via the connecting brackets 84 provided on the vertical frame bases 11a and 12a in a posture close to the left vertical frame 12. As is clear from the figure, when the outer panel 20 is closed, the portion of the garage unit 70 fixed to the frame 10 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, the tight material 34 and the watertight material 33 are interposed between the inner panel 30 and the frame body 10, so that it is tentatively assumed. Even if the wind is strong outdoors, there is no risk of outdoor air or water such as rainwater entering the room. Further, when the inner panel 30 is closed, the outer panel 20 is also closed. Therefore, when it is not needed, it is possible to eliminate the protrusion to the outside.

On the other hand, when the internal panel 30 is opened toward the indoor side, as shown in FIG. 3, the slider 50 moves via the internal link member 52, and the external panel 20 interlocks with the external link member 53. The outer panel 20 opens toward the outside of the room. As a result, the outer panel 20 projecting to the outside functions as a baffle plate, so that even when the outside wind direction is along the surface of the frame body 10, the outdoor air can be efficiently introduced into the room. become. At this time, since the movement of the slider 50 is restricted by the stopper block 51, it is possible to prevent the outer panel 20 and the inner panel 30 from opening more than necessary. Moreover, the slider 50 in contact with the stopper block 51 is restricted from moving in the direction away from the stopper block 51 by engaging the engaging member 57. Therefore, even when the hand is released from the inner panel 30, the outer panel 20 and the inner panel 30 can be continuously maintained in an open state.

Further, since the garage unit 70 is arranged on the indoor side of the outer panel 20, there is no possibility that rainwater will enter the room even when it rains.

Moreover, in the ventilation passage 73, since the intake port 71 is provided close to the right vertical frame 11 with respect to the air outlet 72, the outdoor air introduced from the left side to the right side by the external panel 20 is passed through the ventilation passage. At 73, it will proceed from the right side to the left side. Therefore, in combination with the effects of the reversing passage portions 73a and 74a described above, water such as rainwater can be captured more reliably. By the way, the water captured in the ventilation passage 73 and the auxiliary ventilation passage 74 is discharged to the outside of the garage unit 70 from the open lower end, so that there is no possibility of entering the room. Further, since the cover plate 82 is provided at the upper end of the garage unit 70 so as to cover the upper ends of the ventilation passage 73 and the auxiliary ventilation passage 74, rainwater is generated from the upper gap generated when the outer panel 20 is opened. Even if water such as the above infiltrates, there is no risk of reaching the room.
