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.

First claim

What is claimed is:

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.
