PURPOSE: A ventilating hole structure of a bus roof is provided to prevent a water leakage of the outside of a bus although a ventilator is deformed by forming a protrusion on the bottom surface of the ventilator and to enable continuous use without developing special parts although the kinds of the buses are varied. CONSTITUTION: In a ventilating hole structure of a bus roof, a lower vent housing(10), an upper vent housing(20), a weather strip(30), a ventilator(40), and a fixing screw(60) are formed at a ventilating hole formed in the top of the bus roof. The upper vent housing is combined to the upper side of the lower vent housing, to constitute the basic structure of the ventilating hole. The weather strip is combined between the lower vent housing and the upper vent housing. A protrusion coming in contact with the top surface of the weather strip is formed to the peripheral part of the bottom surface of the ventilator. The fixing screw is inserted from the sides of components to combine the components in combining the upper vent housing and the lower vent housing.
