Abstract A wheel for vehicle tires comprising a hub of synthetic plastic material having opposite axial ends. In the region of one of these axial ends, a first flange of synthetic plastic material and being of one piece with the hub, projects radially from the latter. A second flange also consists of synthetic plastic material and projects radially from the hub in the region of the other axial end. The second flange is in form of a circumferentially almost complete ring the inner surface of which is provided with a circumferentially extending radially inwardly projecting rib. The ring is to be sprung onto the hub and the rib then becomes lodged in a circumferentially extending groove provided in the outer circumferential surface of the hub. The ring can thus be removed when desired.
A small-diameter wheel for transport carts and the like, comprising a hub composed of synthetic plastic material and having one axial end and an other axial end which is provided with an annular groove in an outer circumferential face of said hub axially inwardly of an end face of said other axial end; a first flange of synthetic plastic material of one piece with said hub and projecting radially from the same in the region of said one end; and an annular flange unit of synthetic plastic material provided with a tubular portion extending inwardly of said other end having an inner and an outer circumferential surface and a radial slot extending from one to the other thereof and which may widen in response to elastic yielding of said flange unit, said flange unit further including a second flange which is mirrorsymmetrical relative to said first flange, an annular rib provided on said inner circumferential surface of said tubular portion of said flange unit and having a mating cross section complementary to that of said groove so as to be receivable in the latter with a snap action, and a radially inwardly extending shoulder on said inner circumferential surface axially spaced from said rib and abutting said end face when said rib is received in said groove.
