PROBLEM TO BE SOLVED: To facilitate pulling-out of a rotary drum fittedly attached to a driving shaft of an electric motor in a reel unit detached from a game machine without damaging components in the electric motor side. SOLUTION: The reel unit is constituted by press-fitting a motor shaft of a drum motor in a fitting hole formed in a central hub part of the rotary drum whose outer circumferential face is continuously drawn with a plurality of symbols and attaching the motor shaft to the rotary drum and a rotation driving device. This disassembly device comprises a grip arm gripping the central hub part of the rotary drum, an air cylinder having a rod part projectable toward the central hub part in the gripped state inside a fitting hole, and a base attached with the grip part and the air cylinder. The central hub part is gripped by the grip part, an air pressure is supplied to the air cylinder to project the rod part inside the fitting hole, push the rotary driving shaft in the pulling-out direction, and pull out the rotary driving shaft press-fitted in the fitting hole of the hub part from the fitting hole.
