している。However, in such a conventional one, each wheel is rotated by pushing a pusher, and in particular, a pair of left and right pedals attached to the front wheel is rotated together with rotation of the front wheel. , It is necessary to put the foot on the pedal and synchronize the foot with the rotation of the pedal. Even a small infant whose foot cannot reach the pedal may get in the way of the pedal, or the pedal may get caught on the foot and cause an injury. Therefore, the present invention prevents the front wheel from rotating even when the pusher is pressed, and even a small infant whose foot does not reach the pedal can push the foot in a stable state by putting both feet on the foot, and easily remove the auxiliary member. The purpose of the present invention is to provide a tricycle that also serves as a wheelbarrow that can be used as a stand-alone tricycle.

できる。As described above, the wheelbarrow / tricycle according to the present invention, when an infant is small and is to be used as a wheelbarrow, if the auxiliary member is attached by a very simple operation, the front wheel of the tricycle can be suspended. It is lifted up in a state of non-rotation and can be freely moved by the rear wheel of the tricycle and the auxiliary wheel provided on the auxiliary member, and the pusher for guiding from the rear is pulled up to a height that is easy to use and used. It's easy to use. Further, since the front wheels do not rotate, the infant has stability by placing his / her foot on the foot provided on the auxiliary member, and there is no risk of injury to the foot due to meaningless rotation of the pedal. Further, when the infant grows up and finishes its mission as a handcart, the auxiliary member can be removed by a very simple operation, and the pusher can be pushed down to a lower height to be used exclusively for the tricycle.
