UNDERFLOOR VENTILATION STRUCTURE

PROBLEM TO BE SOLVED: To provide an underfloor ventilation structure preventing air exhausted from a front face exhaust port of a ventilator, from flowing along the inner surface of a rain cover plate and returning to an underfloor space from adjacent underfloor ventilation ports on both sides. SOLUTION: The underfloor ventilation structure is constituted by disposing receiving plates 9 between a foundation 90 and a sill 91 while holding each underfloor ventilation port 8 in between, mounting the underfloor ventilation port 8a with the ventilator 1 for exhausting air in the underfloor space S1 toward the outdoors S2, and providing the rain cover plate 7 to cover the upper part and front face of each underfloor ventilation port. A shielding means is provided for intercepting the flow of the air exhausted from the underfloor ventilation port mounted with the ventilator, into the adjacent underfloor ventilation ports on both sides.
