Abstract
A wheel is partly closed at one side by a hub cap (1) continuous with the rim (6) and is designed to receive an axle from the opposite side. According to the invention, the hub of the wheel consists of a plurality of ribs (14-17) which serve as bearing faces for the axle and whose geometric, axial elongations clear a plurality of spokes (2-5) forming the connection of the hub cap to the rim (6). This enables injection moulding in one operation with the simultaneous provision of an inside cavity behind the hub cap to receive a radially resilient and projecting bead (11) at the end of the axle.
