Abstract

An aspect of the present disclosure provides a vehicle which includes: an electrostatic eliminator that reduces a positive charge of a specific portion or that charges the specific portion with a negative charge, the specific portion being defined as a portion to be positively charged at which a positively charged air flow that flows around a vehicle body during travel starts to vary from a flow along a surface of the positively charged vehicle body to a flow separated from the surface as negative charges are accumulated because of the external factors. The specific portion is constituted from a conductive material with a surface resistance value that is less than a surface resistance value of the electrostatic eliminator. The electrostatic eliminator is constituted from a conductive resin with a surface resistance value in a range of 102Ω or more and less than 1011Ω.

First claim

What is claimed is:

1. A vehicle comprising:
a vehicle body configured to be retained in a state of being insulated from a road surface and to be positively charged by static electricity due to external factors including traveling; and
an electrostatic eliminator that reduces a positive charge of a specific portion or that charges the specific portion with a negative charge, the specific portion being defined as a portion to be positively charged at which a positively charged air flow that flows around the vehicle body during travel starts to vary from a flow along a surface of the positively charged vehicle body to a flow separated from the surface,
wherein the specific portion is constituted from a conductive material with a surface resistance value that is less than a surface resistance value of the electrostatic eliminator,
the electrostatic eliminator is constituted from a conductive resin with a surface resistance value in a range of 10 2 Ω or more and less than 10 11 Ω,
the electrostatic eliminator is in a shape of a tape and with an adhesive provided on at least a part of a surface of the electrostatic eliminator, the surface facing a surface of the specific portion, and
at least one end portion of the electrostatic eliminator is shaped to be bent to contact the specific portion.

2. The vehicle according to claim 1 , wherein the conductive resin is at least one resin selected from the group consisting of fluorine resin, polyester, polyethylene terephthalate, polyvinyl chloride, polypropylene, and a combination of the fluorine resin, the polyester, the polyethylene terephthalate, the polyvinyl chloride, and the polypropylene.

3. The vehicle according to claim 2 , wherein the conductive resin is a conductive fluorine resin.

4. The vehicle according to claim 1 , wherein the specific portion is a wheel nut, a wheel nut cover, a radiator, an engine, a transmission, a differential, or an exhaust pipe.

5. An electrostatic elimination component comprising:
an electrostatic eliminator constituted from a conductive resin with a surface resistance value in a range of 10 2 Ω or more and less than 10 11 Ω; and
a specific portion constituted from a conductive material with a surface resistance value that is less than the surface resistance value of the electrostatic eliminator,
wherein the electrostatic eliminator is in a shape of a tape and with an adhesive provided on at least a part of a surface of the electrostatic eliminator, the surface facing a surface of the specific portion, and
at least one end portion of the electrostatic eliminator is shaped to be bent to contact the specific portion.

6. The electrostatic elimination component according to claim 5 , wherein the specific portion is a wheel nut, a wheel nut cover, a radiator, an engine, a transmission, a differential, or an exhaust pipe.
