- the present invention is not limited to this.
- a base having a predetermined thickness at any of the four corners of the chassis 11 or the upper surface cover 12 position where the load sensor 41 and the aluminum plate 42 are provided
- the opposing surfaces of the chassis 11 and the upper surface cover 12 become the base. You may comprise so that it may be in a non-contact state on other surfaces.
- the present invention is not limited to this.
- the front wheel and the rear wheel may be reversed.
- all the four wheels may be constituted by the driven wheels 21.
- a motor must be added, which is not preferable in terms of increasing the weight of the single-seat mobile device.
- there are disadvantages such as the fact that the wheel 21 cannot be turned due to the friction of the wheel 21 or that the wheel 21 is subjected to a heavy load and the wheel 21 is damaged or the floor is damaged.
- two wheels 21 and 2 with driving are casters 22 capable of rotating 360 degrees as in the above embodiment.
