Abstract
A toy gear box having a gear case in which a worm wheel and a gear wheel having axes of rotation transversely to each other are in operative engagement with each other with a specific gear ratio. The gear wheel is replaceable, and at least one second gear wheel having a second number of teeth different from the first number may be inserted into the gear box, thereby imparting a second gear ratio to the gear box. The gear case (10) has a toothed rim in firm connection with the gear case (10), and the gear case (10) can receive such a toothed rim on another such gear case as a gear wheel.
