ABSTRACT:
A spring drive mechanism which is particularly suitable for mobile toys, for example, such as small toy autos. In a spring drive mechanism of the above-mentioned type, in that the axle of the reversing pinion is a portion of a spring wire which is retained in spring drive mechanism plates, whereby a spring portion which is located on the side of the elongate aperture is constructed as an abutment for displacing the axle of the reversing pinion to thereby form the drive connection. The inner hook-shaped constructed end of the drive spring engages behind a projection on the spring core shaft. When the spring is unloaded, this construction allows for the spring core shaft to further rotate, since the now stationary or more slowly rotating inner end of the spring will not hinder the further rotational movement of the spring core shaft.
