PROBLEM TO BE SOLVED: To provide a game device precisely driving a ride part without being affected by a weight difference of an operator riding on the ride part. SOLUTION: This game device contains the ride part on which the operator rides, a pneumatic actuator 10 expanding/contracting according to air pressure and vertically moving the ride part, a detection means 40 detecting the expansion/contraction amount of the pneumatic actuator 10 and an operation control part 60 controlling the air pressure of the pneumatic actuator 10. The operation control part 60 alternately switch controls in a short time the injection and the discharge of the air to the pneumatic actuator 10 so that the detected expansion/contraction amount is changed along a target control line. |
