However, the three-wheeled vehicle in this proposal only considers the passengers, and there is a problem that the long equipment such as a lawn mower or a hoe used in agricultural work is not taken into consideration, or a piece of equipment is stored.

In addition, the wheel arrangement of the three-wheeled vehicle described in Japanese Laid-Open Patent Publication No. Hei 10-45080 (Patent Document 2) is the same as the above proposal, and there are two front wheels and one rear wheel. However, the main purpose of this proposal is to provide two. The front wheel makes the lower part of the bottom of the car body wider and flat. This proposal also has the problem of not considering the long equipment.

The wheel arrangement of the three-wheeled vehicle described in Japanese Laid-Open Patent Publication No. 2005-306338 (Patent Document 3) is the same as the above-mentioned proposal, and there are two front wheels and one rear wheel, and all of them can be used as the reference for the front wheels. Three wheels are used for steering, and the handling in small places is improved, but this will complicate the organization and have problems in low-cost manufacturing. Moreover, there is a problem that the installation of a long appliance is not considered.
