ABSTRACT:
A spring driven two-wheel toy vehicle in which the weights of the spring drive unit and the transmission gears are distributed such that the toy is laterally well-balanced. In order to simplify assembly, a frame is provided with integrally formed shafts to which various transmission gears are affixed and is integrally provided with steering shaft support bearings. Two transmission gear mechanisms are engaged with the spring drive unit. One on each side for independently transmitting a torque from the drive wheel to the drive unit by one, and transmitting a torque from the drive unit to the drive wheel by the other.
