Included in a toy construction set is a special block having an axle projecting therefrom, the axle having a slot providing a pair of resilient legs with a groove formed near the free end of each leg. A hub has a bore so that the hub can be journaled for rotation on the axle, the bore having an annular rib therein to provide a releasable snap-action retention. A resilient tire is provided so that it can be mounted on the hub to provide a wheel assembly. Also, a crank unit is provided so that it can be attached to the hub to provide a winch assembly, a locking pin then being available to either allow or prevent rotation of the hub on the axle.
