Since 0 is provided in a portion where the interval between the actuators 14 is wide as described above, getting on and off is easy.

Then, the subject who gets into the cabin 12 sits on the seat 72 in the cockpit 11 inside the cabin. In the driving simulator, the main image generation device 111 and the room / side image generation device 112 generate image signals according to a control program that is executed by inputting operation inputs of the subject such as the steering wheel 73, the accelerator pedal 74, the brake pedal 75, and the like. At the same time, the sound generator 113 generates a sound signal. Then, the projector 102 of the video projection device 91 projects the video on the screen 92 with the video signal generated by the main video generation device 111 so that the video is displayed on the screen 92 and the room / side video generation device 1
An image is displayed on the liquid crystal monitors of both the side mirror 79 and the room mirror 93 with the image signal generated by the speaker 12, and the speaker 82 generates sound toward the subject with the sound signal generated by the sound generator 113. Here, this acoustic signal is transmitted through the low-pass filter 118 to the diaphragm 97.
The diaphragm 97 vibrates only with a low frequency component of the acoustic signal, and gives vibration to the subject. Further, the driving simulator is configured such that the drive system servo amplifier device 114 controls each of the actuators 14 according to a control program executed in the main computer 116 with the operation input of the steering wheel 73, the accelerator pedal 74, the brake pedal 75 and the like by the subject as input. By appropriately controlling the expansion and contraction, the cabin 12 is swung so that the subject can simulate the feeling of actual driving.

According to the driving simulator described above, the actuator 14 rotates the ball nut 33 by rotating the motor rotor 36 with the motor stator 37 to move the screw shaft 32 in the axial direction. Since the motor rotor 36 is a penetrating electric motor that allows the screw shaft 32 to penetrate, the stroke can be increased while shortening the overall length of the actuator 14. Therefore, the height of the swing table 13 can be suppressed while securing the swing angle of the swing table 13, and as a result, the cockpit 11
It is possible to improve getting on and off the vehicle.

In addition, when the screw shaft 32 moves in a direction to come off from the ball nut 33, the stopper screw 45 provided in parallel with the screw shaft 32 moves together with the screw shaft 32, and is provided on the stopper screw 45. The stopper 47 provided contacts the contact member 46 of the case 38 to prevent the screw shaft 32 from coming off the ball nut 33. Therefore,
The maximum stroke of the screw shaft 32 can be achieved.
