Abstract
Provided is an inverted pendulum mobile vehicle such as a single-passenger coaxial two-wheel vehicle which is capable of turning with a small turning radius without causing discomfort to a rider or a vehicle occupant or causing a cargo or the like on the vehicle from shifting or falling off from the vehicle. The vehicle comprises a wheel supporting frame (12), a body frame (12) supported by the wheel supporting frame so as to be rotatable around a vertical axial line and carry a rider and or a cargo and a body coupler (52, 78, 70) that couples the body frame relative to the wheel supporting frame in a prescribed dynamic positional relationship. Thereby, even when the wheel supporting frame undergoes a rapid yaw movement either while traveling in a fore-and-aft direction or remaining stationary, the body frame that carries a vehicle occupant or a cargo is allowed to follow the yaw movement of the wheel supporting frame at a slower angular speed and/or acceleration/deceleration so that the vehicle occupant is prevented from experiencing discomfort and the cargo is prevented from shifting on the body frame or falling off from the vehicle.
