(57) A rolling gear for containers in which each wheel (4) extends to a short axle (10),
these forming a single item, and being physically independent from the other wheel
(4), and which operates within the orifices (13,14) in the corresponding pair of tabs
(11,12); these tabs (11,12) feature on their outward side a third tab (17) which is
likewise traversed by the axle (10) of the wheel (4), with the peculiarity that said
tab (17) is connected at its free end, by means of the inclusion of a transversal
wall (18), to the adjacent tab (12), forming in conjunction with the latter a tubular
structure of considerable strength.
