Drive device for toy mounts, characterized in that the traction forces that cause the displacement in the forward direction are of intermittent nature being caused by a friction element wound to a free pinion and attached to a movable point thereof; whose pinion is integrally associated with a connecting element with a similar one fixedly located on the axle of the wheels, the pinion being able to move parallelly also by the section of a static roller with respect to the structural frame, whose roller moves on a projection peripheral side of the pinion provided with a zone in inclined plane to produce the desired effects and incorporating a spring that causes the retraction, of the pinion to the initial position prior to a tensile stress finally having a spring located between the connecting elements,, that causes its distance and therefore its deactivation, when the forward efforts stop and therefore the pinion returns to the position of maximum distance away induced by the roller.
