PROBLEM TO BE SOLVED: To make batter the generation efficiency of the air subjected to living environmental improvement.SOLUTION: The air 8 as a living environmental improvement object in which a partition member 12 is incorporated into an internal space part 3 from an air inlet part 9 is guided so as to be contacted with the branch-leaf 7 of a plant 4 for living environmental improvement stored into the internal space part 3 of a box body 2 capable of lighting, and the air 8 is generated as the air 10 subjected to the living environmental improvement by the metabolism of the plant 4, thus the generation efficiency of the air 10 is made satisfactory. The partition member 12 is composed of a sheet material divided into a plurality of pieces in which the stem 6 of the plant 4 is avoided or a sheet material made into a spiral shape so as to surround the stem 6 thus the application of the damage of the partition member 12 to the stem 6 is considered, and the branch-leaf 7 is arranged at the space separated to the upper and lower directions of the partition member 12.SELECTED DRAWING: Figure 1【課題】生活環境改善済の空気の生成効率が良くなる。【解決手段】仕切部材１２が給気口部９から内部空間部３に取り込まれた生活環境改善対象としての空気８を採光可能な箱体２の内部空間部３に収容された生活環境改善用の植物４の枝葉７に触れるようにガイドし、空気８が植物４の新陳代謝により生活環境改善済になった空気１０として生成されるので、空気１０の生成効率が良くなる。仕切部材１２は、植物４の幹６を避けた複数個に分かれた板材又は幹６を取り巻くように螺旋状になった板材により構成して仕切部材１２が幹６に損傷を与えないよう考慮し、仕切部材１２の上下方向に隔てられた空間に枝葉７が配置されている。【選択図】図１
