PROBLEM TO BE SOLVED: To secure comfortableness for an spectator in the air-conditioned zone above the floor by forming in each of the front and the back of a supporting member an air outlet which communicates with an air outlet passageway in the supporting member and through which air is emitted both frontward and backward horizontally. SOLUTION: In the front and the back of a supporting member 5 a front air outlet 13 and a back air outlet 14 which both communicate with an air outlet passageway in the supporting member 5 and through which air for air conditioning is emitted frontward and backward horizontally respectively are formed. Therefore, warm air can be led from a chamber 4 under a floor part 3, through an air passageway 7 and an air outlet passageway 12 in the supporting member 5, and to the front air outlet 13 in the front 5A and to the back air outlet 14 in the back 5B respectively of the supporting member 5; the warm air is emitted from the front air outlet 13 frontward and from the back air outlet 14 backward horizontally respectively. Accordingly, the warm air can be supplied to both a spectator sitting in a seat 6 in a specified row and another spectator sitting in a seat 6 just behind the seat through a simple constitution. |
