VEHICLE

A vehicle in which separation of positively charged airflow from a positively charged surface of a vehicle body can be prevented is provided. A vehicle body is insulated from a road surface, and positive static charges accumulate on the vehicle body during propulsion. The vehicle comprises a self-discharge device (9) adapted to decrease in positive potential of a window pane (7) at which positively charged airflow flowing along a vehicle surface deviates therefrom during propulsion by discharging the static electricity therethrough to produce negative ions according to the positive potential of the window pane (7).
