As shown in FIG. 2, the communication passage 23 that connects the ventilation port 17 and the opening 24 extends from opposite directions at predetermined intervals and bends the communication passage 23 for rain return. It is preferable to provide a set of rain-bending frame plates 25 and 26. Moreover, the rain return frame plates 25 and 26 may be separate frame materials, and may be made of a heat insulating material or the like in addition to a non-combustible material such as a metal or a refractory material, but preferably have water repellency. Of course. Further, in addition to the rain return frame plates 25 and 26, it is possible to provide a non-combustible fire prevention member having communication holes at predetermined intervals in the communication passage 23. As shown in FIGS. 4 and 5, the ventilation promoting member 30 according to the present invention described in the illustrated embodiment includes a ventilation hole frame piece portion 32 having a ventilation hole 31 communicating with the opening 24 on the outdoor side, and a ventilation hole. A first rain return frame plate 33 located above the rising frame piece portion 34 standing up from one side of the frame piece portion 32 to cover the ventilation hole 31, and a rising frame rising up from the other side of the ventilation hole frame piece portion 32. One piece 3
6 and a second rain return frame plate 35 located above the first rain return frame plate 33 and beyond the tip end portion thereof.

The ventilation hole 31 communicating with the outdoor side opening 24 of the ventilation hole frame piece 32 can promote ventilation in the wall 10 through the ventilation hole 17 and the communication hole 23.
First of all, rainwater or the like trying to enter from the opening 24
It is difficult to enter because 7 is facing downward, and then the vent hole 3
It is difficult to invade by the frame portion around 1, and the ventilation hole 31
Rainwater and the like that have entered from above rise up from one side of the vent hole frame piece 32, cover the vent hole 31, and are positioned above
Entry is blocked by the rain baffle frame plate 33 of the
Rainwater or the like that exceeds the tip of the rain return frame plate 33 is prevented from entering by the second rain return frame plate 35 located thereabove, and the rainwater and the like can be surely prevented from entering the wall body 10 in multiple layers. It can be prevented.

Further, in the illustrated embodiment, the vent hole 31 is composed of a number of slits which are relatively thin, but whether the wall is hit by wind, whether the wall is susceptible to rainwater or not, and the house is placed. Depending on the location and weather conditions that exist, or the corresponding weather conditions on the wall, you can make it larger or smaller,
It can be rounded, elliptical, or set appropriately, and in some cases, by an experimental method against wind and rain,
