気排出口部の逆止弁構造。 A ventilation duct with one end leading to the inside air outlet 2 and the other communicating with the room, and the ventilation duct bored in the valve mounting plate 8 formed on the upper side of the horizontal part 4' of the ventilation duct. It consists of a check valve 6 that fits into a slit 28 in the direction across the duct, an enlarged head 20 that cannot pass through the slit 28, and a tongue-shaped plate part 25 that swings to perform a valve action. A check valve 6 of a thin plate 7 is provided in a direction across the slit 28, and a PP hinge 30 is provided for pressing and locking the enlarged head 20 toward the slit 28. Check valve structure.
