A key system for an automobile according to the present disclosure includes an on-vehicle device configured to transmit and receive a radio signal to and from an electronic key, and a resin panel through which the on-vehicle device is fixed to and held by a body of the automobile. The on-vehicle device includes a transmitter configured to transmit a search signal to the electronic key, a receiver configured to receive a response signal transmitted from the electronic key in response to the search signal, a control unit configured to control the transmission of the search signal, and a resin case. The smart key system for the automobile according to the present disclosure removes electrostatic charging generated by the search signal transmitted from the transmitter in either or both of the resin case and the resin panel.

Smart key system for automobile

A lubricant that enables to improve control stability of an automobile or the like having a vehicle body charged by driving. A lubricant for improving control stability of an automobile includes a base oil and an additive containing a carbon black. A kit for improving control stability of an automobile includes a discharging member including a protrusion that performs a self-discharging by air-ionizing and the lubricant. A method also improves control stability of an automobile.

Lubricant for vehicle having vehicle body charged by driving

One aspect of the disclosure relates to a sliding member. The sliding member includes: a first sliding portion having a first lubricant placed between first parts of a first friction sliding mechanism; and a second sliding portion having a second lubricant placed between second parts of a second friction sliding mechanism. The first sliding portion has a lubricant feed port from which the first lubricant is fed, and the second sliding portion has no lubricant feed port from which the second lubricant is fed. The first lubricant contains base oil and an additive. The second lubricant contains base oil and an additive containing conductive carbon. The second lubricant contains a relatively larger amount of conductive carbon than the first lubricant.

Sliding member

A vehicle is positively charged with static electricity due to an external factor. The vehicle includes a battery, a static eliminator sheet, and a holding member. The battery includes at least one cell, an electrolyte, a resin case, and negative and positive terminals. The resin case accommodates the components and electrolyte of each cell. The negative terminal is grounded to the vehicle body. The positive terminal is supplied with electric power from a charger. The static eliminator sheet is made of a material on a positive side of a triboelectric series with respect to a material of the resin case. The holding member holds the static eliminator sheet and the resin case in contact with each other. The holding member holds the battery at a predetermined location of the vehicle body in a state where the resin case and the static eliminator sheet are slidable due to vehicle body vibrations.

The present disclosure relates to an automotive slide member including a first slide portion having a first lubricant applied between first portions of a first friction slide mechanism, and a second slide portion having a second lubricant applied between second portions of a second friction slide mechanism. The first slide portion is arranged at a part to be touched by an operator who attaches the automotive slide member to an automobile or a user of the automobile. The second slide portion is arranged at a part that is not touched by the operator who attaches the automotive slide member to the automobile or the user of the automobile. The second lubricant contains a relatively larger amount of conductive carbon than that of the first lubricant.

Automotive slide member

One aspect of the disclosure relates to a sliding member. The sliding member includes: a first sliding portion having a first lubricant placed between first parts of a first friction sliding mechanism; a second sliding portion having a second lubricant placed between second parts of a second friction sliding mechanism; and a third sliding portion having a third lubricant placed between third parts of a third friction sliding mechanism. The first sliding portion is in contact with the third lubricant, and the second sliding portion is not in contact with the third lubricant. The second lubricant contains an additive containing conductive carbon, and the third lubricant contains no conductive carbon. The second lubricant contains a relatively larger amount of the conductive carbon than the first lubricant.

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 10&#x3a9; or more and less than 10&#x3a9;.

Vehicle and electrostatic elimination component

The present disclosure provides a technology which can suppress separation of an airflow while a change in an appearance of a vehicle is suppressed. This exemplary embodiment is a vehicle including a self-discharging static eliminator which neutralizes and eliminates positive charges generated on a vehicle body by self-discharging which causes negative air ions to be generated and a transparent conductive material, and the self-discharging static eliminator and the transparent conductive material are electrically continuous.
