Provided is an inverted two-wheel type carrier, which comprises a body (4) having a rack, a carriage (5) supported on wheels (1a and 1b), a moving mechanism unit (7) for displacing the relative positions of the body (4) and the carriage (5), an inclination sensor (6) for detecting the position of the body (4), and a control unit (9) for driving and controlling the wheels (1a and 1b) and the movingmechanism unit (7). By displacing the moving mechanism unit (7) back and forth, a riding seat (8) over the body (4) can always be controlled to a horizontal position even against a slope or step on arunning route, so that a stable run can be realized while preventing a load collapse and giving no feeling of uneasiness to the rider.
