A user can ride on the seat unit 410 , and the seat unit 410 is driven according to a roll operation, a pitch operation, and a heave operation provided through the three-axis motion driving unit 100 . can be

As an example, the seat unit 410 may be a chair, but if it is a configuration that allows the user to receive driving by the 3-axis motion driving unit 100 , there is no limitation in its form.

In addition, the seat portion 410 may have a mono-coque structure, but is not limited thereto.

The multimedia unit 420 outputs at least one of image information, vibration information, and audio information to the user, and may include, for example, a display, a speaker, and a vibration device.

According to the motion simulator 1 of the present invention, By arranging a plurality of actuators to support the load of the boarding part supporting part 120 on which the boarding part 400 is disposed, the driving of the motion simulator 1 during Roll, Pitch and Heave operations is reduced. It has the advantage of being stable.
