Abstract: The present invention relates to clockwork motors for toy vehicles of the type wherein depressing of the vehicle toward a rolling surface engages winding pinions which wind the propulsion spring as the vehicle is rolled against the supporting surface. The spring is housed in a casing to which one end is attached and the casing drives the wheel axle through one gear train. The other end of the spring is attached to a hub journaled in the casing and the spring can be wound by rotation of the hub which is accomplished by said winding pinions when engaged with a gear on the axle.
