The frame plate 10 is composed of a frame-shaped wooden plate. The thickness is about the wall thickness of the building, and when the ventilation facility 1 is attached to the building, it is located inside the wall of the building and cannot be visually recognized indoors or outdoors. Since the frame plate 10 is made of wood, it can be easily fixed in the wall. Further, the window frame portion 3 is fixed to the frame plate 10 using screws, and the opening covering portion 7 is fixed to the frame plate 10 using bolts and nuts. Further, the joint surface between the frame plate 10 located on the outdoor side and the opening covering portion 7 is covered with caulking.

The opening covering portion 7 has a substantially box-like shape without a top plate, and has at least surfaces 7a, 7b, 7c, 7d, and 7e. The surface 7a is a substantially box-shaped surface that is located on the bottom plate surface and extends in the direction along the wall surface of the building, and has a size that covers the opening of the building. The surface 7b is located on the upper end surface of a substantially box shape, and is inclined downward from the indoor side to the outdoor side. Therefore, even if rainwater enters along the wall surface of the building, it is difficult to enter indoors. The surface 7c is located on the lower end surface of a substantially box shape, and is inclined downward from the indoor side to the outdoor side. Therefore, even if rainwater enters along the wall surface of the building, it is difficult to enter indoors. Further, drain holes (not shown) for draining rainwater are provided at the corners (two places) on the outdoor side of the surface 7c. The surface 7a may be provided with a plurality of slits and eaves for taking in natural wind, or a shutter shape may be used.

Four openings 7ac are provided on each of the surfaces 7d and 7e. Further, each of the openings 7ac is provided with an eaves 7ab and a net 7ad. The openings 7ac are arranged in a row in the vertical direction, and similarly, the eaves 7ab are also arranged in a row in the vertical direction. For this reason, the natural wind that hits the outside of the lower eaves 7ab flows upward, hits the inside of the upper eaves 7ab, and flows into the ventilation facility 1, so that the natural wind can be taken in efficiently while being improved. It will have two effects of preventing the ingress of rainwater. Further, in the present embodiment, three sides of a quadrangle having a predetermined size among the surfaces 7d and 7e are cut, and the remaining one side is bent outward to simultaneously form the opening 7ac and the eaves 7ab. .. In addition, 5 or more openings 7ac and 7ab eaves may be provided on one surface, or 3 or less may be provided.

As shown in FIGS. 5 and 6, a wind direction changing plate 7ae is provided inside the opening covering portion 7.
