In addition, although FIG. 5 demonstrates the case where the hand-wheeled three-wheeled vehicle (X) is mounted on the horizontal ground (P), it is not limited to this, The ground of a slope or an uneven ground may be sufficient. The object (Y) can be transported by the same operation and handling as in FIG.

In FIG. 1 to FIG. 5, the hand-held three-wheeled vehicle (X) is not limited to the application for one-year-old and two-year-old, and can also be applied to three-year-old and four-year-old. The term “age” means the loading volume of the vehicle body (1), for example, the volume of the bucket (9), and the age is 1 cubic. And in a unicycle for 3 years old and over, the volume and weight of the object to be loaded reaches a large weight and a large volume of, for example, 60 kg or more. It is difficult to travel while moving or to change the direction of the car body, and the car body may be inclined during transportation of the transported object, which may cause the transported object to fall. The hand-held three-wheeled vehicle (X) shown in FIGS. 1 to 5 supports the vehicle body (1) with one front wheel (Z2) and two rear wheels (Z1) and (Z1) as described above. Therefore, even if it is for a three-year-old or more who transport a large volume, heavy object to be transported, a person such as an operator can push and pull the handle (5) without lifting the vehicle body (1). A large volume and heavy object (Y) can be easily transported simply by acting, and the direction change of the vehicle body (1) is also one of the two rear wheels (Z1) and (Z1). By simply floating (Z1) from the ground, the vehicle body (1) can be easily supported while being supported by the front wheel (Z2) and the other rear wheel (Z1). In addition, since the handle (5) is located around the waist of a person such as an operator, the person such as the worker bends a large volume, heavy object to be transported (Y) even if the person is three years or older. It can be transported with the back extended. For this reason, the hand-held three-wheeled vehicle (X) according to the present invention is particularly suitable for a three-year or four-year-old vehicle that transports a transported object (X) having a large loading volume and a large loading weight. You can say that.
Further, the vehicle body (1) is not limited to the vehicle body frame (6) and the bucket (9), and in the vehicle body (1), the structure of the vehicle body frame (6) and the bucket (9) is It is changed appropriately according to the two-year-old or three-year-old hand-held tricycle.

  The present invention is suitable for transporting objects to be transported such as construction sites and agricultural sites.
