PROBLEM TO BE SOLVED: To provide a slot machine 10 capable of suppressing the rise of a temperature inside a case body 11 by accelerating heat radiation of a driving motor 120 or the like. SOLUTION: In the slot machine 10, a reel unit 60 comprises a plurality of driving motors 120, rotary reels 40 provided on the rotary shafts of the respective driving motors 120, and a cooling fan 130 provided at the rotary shaft of at least one driving motor 120, and the flow of air is formed in either left or right direction along the axial direction of the rotary reels 40 inside the reel unit 60 by the cooling fan 130. Of both left and right side parts of the reel unit 60, the upstream side of the flow of the air is turned to an intake part and the downstream side is formed as an exhaust part. Inside the case body 11, at least one of an intake duct 72 for communicating between the intake part and the outside of the case body 11 and an exhaust duct 71 for communicating between the exhaust part and the outside of the case body 11 is provided.
