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. When such extraneous substances adhere or the like to an ozone purifying body, the purification sites thereof are clogged and the ozone purification function deteriorates. Therefore, when a predetermined removal implementation condition is established, control is executed to inject cleaning liquid from an injector 20 to enhance the fluidity of the extraneous substances and wash the extraneous substances away. The function of the ozone purifying body can thereby be restored.

The present invention provides a method for reducing concentrations of ozone and nitric acid produced in cooling air flowing through a circulating airflow path of a rotary electric machine, the method including: disposing an ozone decomposition unit containing an ozone decomposition catalyst in the circulating airflow path; and allowing the cooling air to pass through the ozone decomposition unit so as to decompose ozone and to suppress production of nitric acid. According to the present invention, the method and device are capable of reducing the concentrations of ozone and nitric acid produced in the cooling air flowing through the circulating airflow path of the rotary electric machine for a long period of time while preventing pressure loss.
