To solve the problem that there are wearing of a support member, travel disturbance due to catch to irregularity of a floor surface, and impediment to miniaturization in a coaxial two-wheel travel vehicle provided with a trestle, though the travel vehicle prevents rotation of the trestle to the reverse direction of driving wheels caused by reaction force of driving force by extending the support member usually grounded to the floor surface from the trestle to the floor surface during travel.
The driving wheels are fitted to the respective driving shafts provided to project nearly coaxially from the both sides of the trestle as well as on the centers of gravity of the sides. The vehicle is provided with a vertical detection means rotatably borne so as to be always positioned in the vertical direction to the driving wheels, and a weight member rotatably journaled in a direction orthogonal to the driving shafts. The vertical detection means and the weight member are connected by a link mechanism. The weight member turns according to inclination of the trestle to the floor surface and displaces the center of gravity to a direction of correcting the inclination of the trestle so as to correct the inclination of the trestle. Accordingly, the support member is unnecessary, and the wearing and the travel disturbance caused by hang-up to the floor surface are eliminated, which allows miniaturization.
