A collapsible Ferris Wheel has a shaft with a central hub section and two outer sections detachably interconnected, the outer shaft sections being journaled in legs swingably supported on respective carriages while a further carriage, sandwiched between the other two, has a cradle to receive the hub section upon disassembly of the structure. The legs, which come to rest on their carriages in the collapsed position, may have telescoped extensions carrying the journal bearings for the shift and are also provided with hoods projecting upwardly in that position while being downwardly open to receive the upper ends of elevating jacks rising from these carriages.
