In order to achieve such aim, the game device according to the present invention comprises a handle unit for operating the movements of a virtual vehicle in a game program, and controls the movements of such vehicle in correspondence with the operating signal from the handle unit. For these purposes, a movable body is supported by a fixed body in a freely tilting position. The pulley of the handle unit rolls along a belt when the rotation torque of the AC servomotor is high, and the rudder input from the steering wheel is directly communicated to the movable body.
