PROBLEM TO BE SOLVED: To prevent the inner part of a game island base from being contaminated with dust, tar of cigarette or the like by providing an air flow generating means for running the internal air of the game island base and a purifying means interposed in a prescribed of this air flow to purify the air flow. SOLUTION: An air supplying passage 10' is formed on the upper part of an upper surface plate 10 covering the upper part surface part of a game island base 1, an air circulating unit 13 is disposed about in the center thereof, a plurality of intake ports 12 are arranged on the center lower surface of the upper plate 10, and flexible pipes 11 and outlet ports 14 are arranged on the lower surfaces in both side ends thereof. A blowing fan 16 is driven by a driving motor 15 and rotated, whereby the internal air of the game island base 1 is sucked into the air circulating unit 13 through the intake ports 12, passed through a purifying filter 17 to remove dust and smoke and tar of cigarette, and then supplied to the flexible pipes 11 and outlet ports 14 through the air supplying passage 10' so as to be refluxed again into the game island base 1.
