Description

Electricity removal structure and vehicle Technical Field The present invention relates to a vehicle power removal structure and a vehicle. Background Since the vehicle is electrically insulated from the ground by the tire having low conductivity, if static electricity is generated in the vehicle, the electric charge is charged in the vehicle body or the like. Patent document 1 describes a technique of reducing a charge amount of a specific member by reducing a charge amount of the specific member by self-discharging a self-discharging type charge remover fixed to a surface of the specific member constituting a displacement transmission system or the like. Patent document 1 Japanese patent laid-open publication 2016-049880 Disclosure of Invention Electromagnetic wave noise generated in various electric vehicle-mounted devices such as automobile recorders, on-vehicle devices, automobile bodies and the like are electrified. It is known that electrification of a vehicle body or the like adversely affects the drivability and running stability of the vehicle. Therefore, in addition to the technology described in patent document 1, it is desirable to further suppress the influence of electromagnetic wave noise generated in the equipment mounted on the vehicle body. The purpose of the present invention is to provide a power-off structure that suppresses the influence of electromagnetic wave noise generated in equipment mounted on a vehicle body. The present invention relates to a power removing structure including a wiring for connecting one end portion to electric equipment mounted in a vehicle and connecting the other end portion to a negative terminal of a battery mounted in the vehicle or to a ground portion of the vehicle, wherein electromagnetic wave noise generated in the equipment is caused to flow to the negative terminal of the battery or to the ground portion through the wiring. Effects of the invention The present invention can provide a static elimination structure that suppresses the influence of electromagnetic wave noise generated in equipment mounted on a vehicle body. Drawings Fig. 1 is a diagram showing a schematic configuration of a vehicle including a charge removing structure according to embodiment 1 of the present invention. Fig. 2 is a diagram showing a configuration example of a charge removing structure according to embodiment 1 of the present invention. Fig. 3 is a diagram showing a configuration example of a charge removing structure according to embodiment 2 of the present invention. Fig. 4 is a diagram for explaining a self-discharge type static eliminator in the static eliminator structure according to the present invention. Fig. 5 is a diagram showing a configuration example of a charge removing structure according to embodiment 3 of the present invention. Detailed Description Hereinafter, embodiments will be described with reference to the drawings. Further, since the drawings are simplified, the technical scope of the embodiments cannot be narrowly interpreted based on the description of the drawings. The same reference numerals are given to the same elements, and duplicate descriptions are omitted. In the following embodiments, when the number of elements and the like (including the number, the numerical value, the amount, the range and the like) are mentioned, the number is not limited to a specific number, but may be a specific number or more, or may be the following, unless the number is particularly clear and the number is obviously limited to a specific number in principle. In the following embodiments, the constituent elements are not necessarily required, except for the cases that are particularly clear and the cases that are regarded as being necessary in principle. In the same manner, in the following embodiments, when referring to the shape, positional relationship, and the like of constituent elements and the like, elements and the like approaching or resembling the shape and the like are substantially included, except for the case where they are particularly clear, the case where they are not considered to be clear in principle, and the like. This is also true for the above amounts and the like (including numbers, values, amounts, ranges, etc.). < Discussion about the charge eliminating structure 2 according to the contemplated embodiment > When a vehicle such as an automobile runs, air flows in frictional contact with the vehicle, and static electricity is generated in the vehicle. Static electricity is also generated due to repeated contact and separation of each part of the tire with the road surface, relative movement of components in an engine, a brake device, and the like, along with rotation of the wheel. Since the vehicle is substantially electrically insulated from the ground by the low-conductivity tire, if static electricity is generated in the vehicle, a main positive charge is charged in the vehicle body or the like. Therefore, a structure is known in wh
