PURPOSE:To make air conditioning achievable by making any air contained with tobacco's smoke and smell so as not to flow into a nonsmoking seat area side from a smoking seat area side adjacently set in the same compartment. CONSTITUTION:An interval between a smoking seat area 2a and a nonsmoking seat area 2b adjacently set up in the same compartment 2 is partitioned off by a partition wall made up of leaving a passage 4 for passersby plying between both of them, while air in both these areas 2a and 2b is inhaled through and, after being air-conditioned, air charging is carried out for both these areas 2a and 2b, and thus air conditioning takes place, and in this time, an amount of air supply in the smoking seat area 2a should be set to be larger than that of the nonsmoking seat area 2b. With this constitution, an air current 6 into the 2b side from the 2a side is produced, thereby preventing any air containing the smoke and smell of tobacco at the side of the area 2a is made so as not to flow into the nonsmoking seat area 2b, so the area 2b side is separated from the area 2a in terms of tobacco smoke. |
