For this reason, each of the folded passages also communicates with each other in the left-right width direction, and the outside air flowing into each of the folded passages is once divided right and left, and then divided outside air is divided into the other folded passages. It can be efficiently taken into the room by the ejector effect by merging with the diverted outside air diverted in the road.

At this time, since the outside air passes over the left and right side edges of the respective flow path forming column portions facing the folded flow path while meandering in a folded shape, rainwater or the like entering with the outside air flows. Almost all are received by the side walls of the flow path forming column, so that rainwater or the like can be reliably prevented from entering the room. In addition, the flow path forming column is extended in the up-down direction and formed in a U-shaped cross section, and the flow path forming column near the front side horizontal blade body is provided with the U-shaped opening face standing rearward. On the other hand, since the channel forming column portion close to the rear lateral blade body has the U-shaped opening face standing forward, it is possible to form a folded channel by simplifying the structure. In addition, good ventilation can be ensured, and rainwater or the like can be reliably prevented from entering the room.

Further, since a water catching groove is defined by a plurality of divided pieces in the left-right width direction in the concave groove formed in the center of the pillar main body of the flow path forming pillar, the water enters along with the outside air. Part of the rainwater, etc. is caught in the trapping groove defined as an air pocket by the divided pieces of the concave groove, and flows down along the inner surface of this trapping groove. As a result, the water trapping effect is further improved Thus, it is possible to reliably prevent rainwater or the like from entering the room.

According to the second aspect of the present invention, the first aspect is provided.
In addition to the effect of the above, since the drainage hole communicating with the water catching groove is formed in the mounting plate of the flow path forming column, rainwater and the like trapped in the water catching groove, As a result, the water is drained to the outside, and as a result, the water catching effect is further improved, and it is possible to more reliably prevent rainwater or the like from entering the room.

According to the third aspect of the present invention, in the first aspect,
Or in addition to the effect of 2, since the front outside air inflow body and / or the rear outside air inflow body are formed as a plurality of horizontal blade bodies which are horizontally suspended at an interval in the vertical direction on the front side of the peripheral supporting frame, Since the outside air inflow does not protrude from the outer wall of the building, the generation of wind noise can be prevented, and the stiffness structure is firm and hard to break,
Security and the like are improved.

According to the fourth aspect of the present invention, there is provided the first aspect.
In addition to the effect of 2, the front outside air inflow body and / or the rear outside air inflow body are made of a perforated plate having a large number of holes, so that the outside air inflow body does not protrude from the outer wall of the building. The generation of wind noise can be prevented, the outside air can be widely and smoothly introduced into the room from the opening and taken in, and the waterproof effect is almost the same as that of the horizontal blade body, and the wig can be thinned. In addition, the design can be freely selected according to the customer's preference, and the design is improved.

According to the fifth aspect of the present invention, there is provided the first aspect.
Or in addition to the effect of 2, the front outside air inflow body or the rear outside air inflow body is the horizontal blade body, and the other rear outside air inflow body or the front outside air inflow body is a perforated plate having a large number of holes. As a result, horizontal blades and perforated plates can be placed in the right places
Each type of outside air inflow body can be provided with an effect peculiar to the outside air inflow body.
