It may be formed to block only the ceiling of the , or to block both the ceiling and sides.

In addition, the plurality of wind variable membranes 40 may be provided with a plurality of fine vent holes 40c on the surface to provide a passage for air to flow even in a blocked state.

When the plurality of wind variable membranes 40 as described above are expanded as shown in FIG. 4( b ), the cooling wind discharged from the ventilator 20 is first discharged into the space between the bus and the variable wind membrane 40 . to be evenly distributed in the corresponding space, and then supplied to the passenger boarding unit through the ventilation holes 40c of each wind variable membrane 40 due to a temperature difference or a density difference in a state in which the cooling wind is spread.

Through this, the cooling wind discharged from the ventilator 20 is transmitted indirectly without wind instead of being transmitted as a direct wind to the passengers, so that the cooling wind can be felt softly, and it is not transmitted strongly only to some locations, but is evenly distributed throughout the inside of the bus. It can exhibit the effect of uniformly delivered.

In addition, it is also possible to prevent direct transmission of heat generated by light reaching the bus surface between the bus surface and the passenger board with cooling wind from being transmitted directly to the passenger board.
