Device for sliding toy vehicles, essentially characterized by the fact of being constituted by a pair of equal, preferably transparent boxes, each of which has inside a continuous conduit forming a continuous circuit that runs along the sides or contour of the box, said duct having a large longitudinal opening in the portion thereof, located in the lower part, there being also, within said duct of each box, a group of several spheres or balls, whose diameter must be such that having the possibility of running freely inside the duct, passing through the lower portion of the duct that is open partially reach through the opening, so that they can establish a tangent contact with the plane of the sliding surface, so that when the vehicle being carried by the support boxes is dragged, the balls will turn on the surface and push each other irrigating through the interior of the duct, serving as means of sliding the vehicle.
