An object of this invention is to provide an atmosphere-cleaning device for vehicles that is capable of restoring the function of an ozone purifying body carried by a vehicle component. Mud, dust, snow-melting agents as well as SOx and NOx are scattered into the atmosphere as a result of being swirled up by a preceding vehicle or due to weather and climate conditions.
