ることを特徴とする建物用換気装置。 A housing 2 in which an intake port 2a is formed on one side surface of the outdoor side or an indoor side, and an exhaust port 2b is formed on the other side surface, an upper partition plate 3 that hangs down from the top surface inside the housing 2, and a bottom surface of the housing 2. The lower partition plate 4 stands up from the upper and lower partition plates 3, 4.
A damper 5 is placed in an opening between the damper 5 and rotates around a horizontal axis to open and close the opening, a first cam 6 provided in a lower damper part 5b located below the axis of this damper 5, and a damper The second cam 7 provided on the upper damper part 5a located above the axis of the damper 5 rotates around an axis parallel to the axis of the damper 5, and its tip contacts the first cam 6 to move the damper 5. While closed,
a crank 8 that contacts the second cam 7 to open the damper 5;
Recesses 6a and 7a are formed in each end position of each cam 7 where the tip of the crank 8 contacts, and the tip of the crank 8 is engaged with the damper 5.
For use in buildings, the damper 5 is engaged with the recess 6a of the first cam 6 when the damper 5 is closed, and with the recess 7a of the second cam 7 when the damper 5 is opened, thereby maintaining the open and closed state of the damper 5. Ventilation equipment.
