PROBLEM TO BE SOLVED: To prevent an increase in pressure loss of air flow in the casing by installation of an ultraviolet irradiator by providing an ultraviolet irradiation means on the inwall of an air duct, in an air cleaner provided with the air duct, a blowing means, a filter member carrying a catalyst and an ultraviolet irradiation means. SOLUTION: When the operation of an air cleaning unit 1 is instructed, a fan 5 is driven, air in a vehicle room is guided from an air suction opening to the casing 2. However, at this time, air passes through a dust removing filter 6. At this time, dust in the air is removed. Air passing through the dust removal filter passes through a deodorization filter 6 provided with a photocatalyst. At this time, odor components in the air are adsorbed by the filter 6 provided with a photocatalyst. Cleaned air is ejected into the vehicle room from an air diffuser. As the ultraviolet irradiator 9 is fitted into the inclined wall 10 of the casing, draft resistance in the interior of the case 2 can be lowered significantly as compared with when provided in the center of a draft channel. |
