ABSTRACT:
The two-speed drive mechanism for toys of the present invention comprises, in order to utilize the spiral spring releasing force as the source of driving power, a mechanism element interconnecting through a gear mechanism a spiral spring shaft fixed with one end of the spiral spring and an output shaft for taking out the power; a mechanism element for deciding to change or not to change the rotational speed by acting or not acting on the output shaft of the aforementioned mechanism element; and an interconnecting gear group for interconnecting the spiral spring shaft and the aforementioned elements so that the working time of the latter mechanism element may be effected later by certain rotations than the point of time the spiral spring begins to rotate (when releasing).
