Storage shelf base and item of furniture or household appliance

A storage shelf base for an item of furniture or household appliance, includes a base plate stationarily secured to a body of the item of furniture or household appliance, a support plate arranged on the base plate, and a storage shelf, which is positively driven relative to the support plate and can simultaneously be moved rotationally and translationally. Facing bearing surfaces of the support plate and the storage shelf have respective at least substantially closed circulating running grooves, in which rolling elements are guided. The storage shelf is movable relative to the support plate, out of an initial position into an intermediate position, in an opening movement, in which the storage shelf is rotated relative to the support plate in a rotational direction and shifted in a predetermined direction and can be moved out of the intermediate position back into the initial position in a closing movement. The support plate has a closing-support device supporting the closing movement of the storage shelf.
