PROBLEM TO BE SOLVED: To promptly ventilate the interior of a booth by sucking and exhausting air in a booth room over a wide plane. SOLUTION: A side board 7 is of an inner/outer double structure consisting of an inner panel 7b and an outer panel 7a separate from each other and an air passage 14 directed vertically is formed thereinside. The air passage 14 is partitioned into upper and lower parts at a predetermined height so that the lower part serves as an air supply passage 16 while the upper part serves as an exhaust passage 17. An air outlet 21 for supplying air into the booth room is provided at the lower end portion of the inner panel 7b. A number of suction holes 23 in communication with the exhaust passage 17 are provided in the portion of the inner panel 7b above the partition, and the upper portion of the exhaust passage 17 is connected to an exhaust unit 30, whereby air introduced into the air supply passage 16 is caused to flow into the booth room via the air outlet as air in the booth room is sucked into the exhaust passage 17 via the suction holes 23 and exhausted to the outside.
