ABSTRACT:
A pressure control device of buoyancy disk game machine comprises a motor and a fan, characteristic in that a plurality of openings are installed on the pillar of the fan. Thereby, the reversed pressure within the space of the game machine may be released from the opening, thus the wind resistance of the fan blade may be reduced, and the motor temperature is also reduced.
