In a vehicle having a microscopic dynamics friction mechanism formed of at least two parts and charged to a positive potential due to traveling, a lubricant in which first additive fine particles made of a resin that generates a negative potential are uniformly mixed with an electrically insulating base oil is disposed in a clearance between members of the friction mechanism.
