PURPOSE:To enable to ventilate individual room or whole rooms by means of natural wind by a structure wherein a ventilation flue, the indoor openings of which are provided between ventilating holes equipped at the windward side and leeward side of a building. CONSTITUTION:Said ventilating device consists of the ventilating holes 15 and 16 equipped at the outside wall surfaces at the windward side and leeward side of the building such as multiple dwelling house or the like, the ventilation flue 17 connecting between said ventilating holes 15 and 16 and the openings 20-23 communicating said ventilation flue 17 with respective rooms 1-4 of the building. According to the structure as described above, for example, in order to ventilate only the leeward room 3 naturally, it is enough to open the window 12 of the room 3 only. Even under the condition that the respective windows 10 and 11 of the windward rooms 1 and 2 are closed and furthermore the doors of the leeward rooms 3 and 4 and of the windward rooms 1 and 2 are closed, natural wind enters from the ventilating hole 15 into the ventilation flue 17 and, through the ventilation flue 17, flows from the opening 22 in the room 3 and circulates said room 3 to escape from the window 12 to outside, resulting in ventilating the room 3. |
