BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.

In other words, the slag structure according to the present invention is attached to the ventilation port formed in the wall portion so that ventilation can be performed, and the sill body is attached to the peripheral support frame body fitted and fitted in the ventilation port. In addition to being detachably attached, the main body also has a guide body support frame body, a front outside air guide body attached to a front side portion of the guide body support frame body, and a guide body support frame body behind the front side outside air guide body. The rear side outside air guide body is attached.

In this way, since the burrs main body is detachably attached to the peripheral edge support frame fitted and fitted in the ventilation port, the burrs main body having a desired opening ratio is preliminarily set in a factory or the like. It is possible to complete the installation work simply and surely by simply assembling it and then loading the slag body to the site and attaching it to the peripheral edge support frame at the site, thus improving the installation work efficiency. .

At this time, the main body is
Since it is possible to assemble the front outside air guide body and the rear outside air guide body to the guide body support frame, it is possible to ensure good accuracy of the opening ratio by the front and rear outside air guide bodies, and to improve ventilation. The efficiency can be kept good.

Here, in the front outside air guide body, a plurality of front side vane pieces extending in the left-right direction are laterally bridged between the left and right side frame forming portions of the guide body supporting frame body with vertical intervals therebetween. , Each of the front side blades has a supporting wall portion extending in the left-right direction, a rising wall portion formed by rising upward from an upper end edge portion of the supporting wall portion, and a downward hanging portion from a lower end edge portion of the supporting wall portion. The hanging wall portion of the front horizontal blade piece arranged in the upper stage and the rising wall portion of the front horizontal blade piece arranged in the lower stage are opposed to each other with a space in the front-rear direction. And a front side outside air flow path is formed between the both, with a part thereof facing substantially vertically downward.

In this way, a front outside air flow path is formed between the front side lateral blade pieces which are vertically laid across each other, and a hanging wall portion of the front side lateral blade pieces arranged in the upper stage is formed. , A part of the front outside air flow path formed between the rising wall portion of the front side vane piece arranged in the lower stage can be a flow path that is directed substantially vertically downward, so that through this front side outside air flow path Even when rainwater or the like flows in together with the outside air, the rainwater or the like can be made to flow downward, and it is possible to reliably prevent the rainwater or the like from entering the room.

On the other hand, in the rear outside air guide body, a plurality of rear side vane pieces extending in the left-right direction are laterally bridged between the left and right side frame forming portions of the guide body supporting frame body with a vertical interval. With
Each of the rear lateral blade pieces has a support wall portion that extends in the left-right direction, a rising wall portion that is formed by rising upward from the upper end edge portion of the support wall portion, and hangs downward from the lower end edge portion of the support wall portion. The hanging wall portion of the rear horizontal blade piece arranged in the upper stage and the rising wall portion of the rear horizontal blade piece arranged in the lower stage are spaced apart in the front-rear direction. The rear outside air flow passages are arranged so as to face each other, and a part of the rear outside air flow passage faces substantially vertically upward.

In this way, a rear outside air flow path is formed between the rear lateral blade pieces which are vertically laid horizontally with a space between them, and the rear lateral blade pieces arranged in the upper stage hang down. Since a part of the rear outside air flow passage formed between the wall portion and the rising wall portion of the rear side vane piece arranged in the lower stage can be formed as a flow passage that is directed substantially vertically upward, The rear outside air flow path can more reliably prevent rainwater and the like from entering the interior together with the outside air.

The rag main body further includes a perforated plate disposed between the front outside air guide body and the rear outside air guide body.

As described above, the aperture ratio can be easily changed by providing the perforated plate on the slag body.

At this time, by arranging a plurality of perforated plates side by side in the front-rear direction, the change range of the aperture ratio can be increased and a desired aperture ratio can be obtained.

Since the slurper body thus set to the desired aperture ratio can be assembled in advance in a factory or the like as described above, it is possible to provide the slurper body with a desired aperture ratio with high accuracy. it can.
