    摘要： A racing toy vehicle in the form of a generally annular main support structure having a rolling surface about its outer periphery and defining a hollow, open or closed interior cavity. The main support structure may be constructed of a rigid or resilient; solid, hollow or inflatable material. In one embodiment, the axial length of the support structure is less than its diameter but greater than the width or shoulder-toshoulder dimensions of a human for receiving at least a single passenger in a fetal position seated along a major arc of the interior cavity. Hand grips formed on the interior surface of the main support structure on a line parallel with the cylinder axis enable the passenger to shift his body weight by appropriate manipulation and turn head-over-heels while riding within the cavity resulting in self-propulsion of the vehicle. The device also includes a braking assembly associated with the hand grips, a seat formed integrally with the main support structure, asymmetrical weight distribution to achieve a whip effect during rolling movement, and may be used in conjunction with a carriage or stand having rollers to facilitate stationary tumbling.
