Claims

[Scope of utility model registration request]

The vehicle includes an exhaust passage opened in the outer wall surface of the body and communicating between the interior of the vehicle and the outside of the vehicle, and an exhaust port unit inserted into the exhaust passage, and the exhaust port unit forms a vent corresponding to the exhaust passage. grit, a tongue elastically supported so as to open and close the vent by wind pressure, and a position located downstream of the tongue from the inflowing air from outside the vehicle so that the tongue closes the vent. In the vehicle body ventilation structure, the support frame is provided with a plurality of first ventilation holes penetrating in the exhaust direction at a predetermined interval from each other, and the support frame is provided with a plurality of first ventilation holes at a predetermined interval from each other. A ventilation hole structure for a vehicle body, characterized in that a second ventilation hole is formed at a position corresponding to the first ventilation hole at a predetermined interval while overlapping the support frame.
