Is often provided with a ventilation ventilator to reduce the effects of wind such as outside wind and prevent rainwater from entering. The basic structure of a conventional ventilation ventilator is that a ventilation tube fitted in an open state at the outdoor opening end of a ventilation air passage communicating between the room and the outside, and a gallery provided outside the outdoor side opening end of the ventilation tube. And a hood that is covered with a rag to surround the upper side, the side, and the front of the outdoor opening end of the ventilation tube.

For example, as shown in Japanese Utility Model Laid-Open Publication No. 1-169737, as shown in FIG. 10, a hood 101 has a hemispherical shape in which a lower portion is opened in an arc shape, and a gallery 101 has a laterally arranged small eave-like shape. A plurality of gusset bars 103 are provided. Further, Japanese Utility Model Publication No. Hei 3-11642 discloses a rattle having no ratchet but having a vertical symmetrically arranged slanting bar. The former is food 101
And the gusset bar 103 prevent intrusion of wind and rain. The gusset bar 103 is in the shape of an eave and has a ventilation section 10 outside the ventilation section 104.
4 has an overlap, so that direct entry of rainwater from the ventilation section 104 is temporarily prevented. The raindrops adhering to the gusset bar 103 accumulate as drops on their free edges along the slope of the gusset bar 103 and drop.

[0004] However, in the horizontal arrangement of the galley bars 103, the raindrops accumulated as drops on the free edges of the galley bars 103 are subjected to the blowing action of the external wind or the air sucking action in the case of ventilation by air supply, so that the interior of the gutter bars 103 is not subjected to the internal operation. There is a problem of getting into. In the case of the vertically-arranged gull-bars as in the latter case, the above-mentioned problems can be solved to some extent because rainwater flows down the gull-bars and drops are hardly formed. However, if the latter is applied to a device with a hood, there arises a problem that when used for exhaust, a ventilation flow collides with the hood, and when used for air supply, pressure loss increases due to interference of the hood.
