Claims

[Scope of utility model registration request]

A ventilation duct 4 with one end leading to the inside air outlet 2 and the other communicating with the interior of the room, and the bench bored into the valve mounting plate 8 formed on the upper side of the horizontal part 4' of the ventilation duct 4. It consists of a check valve 6 of a tongue-like thin plate 7 that fits into a slit 28 in a direction transverse to the rayon duct 4, and the check valve 6 has an enlarged head that cannot pass through the slit 28 in order from above. 20, a reduced neck portion 21 that approximately matches the slit 28, a protruding stepped lock portion 22 that locks onto the edge of the slit after elastically deforming and passing through the slit 28, and a flat plate portion 25 that swings to perform a valve action. A check valve structure for an inside air outlet portion, characterized by comprising a tongue-shaped thin plate 7 consisting of a tongue-like thin plate 7.
