PURPOSE:To provide an air cleaning device for a three-dimensional structure capable of cleaning the contaminated air in the spaces below the artificial ground without requiring space and without impairing beautiful appearance. CONSTITUTION:This air cleaning device 21 for the three-dimensional structure is constituted by providing the three-dimensional structure, which is provided with the artificial ground 3 on a first ground 1 and is delineated with the spaces 5, 7 above and below by this artificial ground 3, with soil 31 formed to permit the flow of air in a vertical direction on the artificial ground 3 and a planting section 23 consisting of plants 33 implanted on this soil 31. The device is further provided with an air passage 25 communicating the space 7 below the artificial ground 3 and the bottom of the soil 31. This air passage 25 is provided with a fan 27 for allowing the air to flow from the space 7 below the artificial ground 3 toward the bottom of the soil 31. |
