## Abstract

A vehicle is provided in which separation of positively charged airflow from a positively charged surface of a vehicle body can be prevented. 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 adapted to decrease a positive potential of a window pane at which positively charged airflow flowing along a vehicle surface deviates therefrom during propulsion by discharging the static electricity through the airflow to produce negative ions according to the positive potential of the window pane.

## Claims

### Claim 1

A vehicle, in which positive static charges accumulate on a vehicle body insulated from a road surface during propulsion of the vehicle, comprising:
a self-discharge device that decreases a positive potential of a window pane of the vehicle body at which a positively charged airflow flowing along a vehicle surface of the vehicle body starts to deviate therefrom to flow away from the vehicle surface of the vehicle body, during the propulsion of the vehicle, by self-discharging to produce negative ions according to the positive potential of the window pane; and
a door frame including the window pane, wherein
the window pane is arranged in an upper area of a side of the vehicle body in a height direction of the vehicle; and
the self-discharge device is a sheet made of a material having high electric conductivity and attached to an inner face of the window pane, and the sheet includes a knurled edge or a knurled surface wherein a corona discharge is caused
wherein a door is fitted into the door frame of the vehicle body, the window pane is arranged in the door, a weather strip is attached to an inner face of the door, and the self-discharge device is attached to outside of the weather strip on the inner face of the door.
