SOLUTION: This air cleaning device is formed in such manner that the outside air is taken into a vehicle surrounding a cockpit through a filter 3. On this occasion, a part of a filter 3 (3A, 3B, 3C) or the whole filter is constituted with a photocatalyst member (for example, titanium oxide) which is activated by light. This filter 3 (3A, 3B, 3C) is mounted on a roof 4 of the vehicle, and an upper roof 4 (4A) of the filter 3 (3A, 3B, 3C) is made of a transparent plastic 5. |
