A clothes washing machine includes a washing tub and a perforated cylindrical drum adapted to rotate about its own axis. A dynamic unbalance preventing arrangement primarily includes a plurality of annular, ring-shaped hollow bodies whose axes coincide with the axis of said drum. The hollow bodies have a sealed construction and are firmly attached to the cylindrical drum. Several movable balancing weights are arranged in a freely slidable manner inside the hollow bodies, which are grouped into two distinct assemblies. The hollow bodies of the two assemblies are provided to respectively adhere against the opposite bases of the drum. The hollow bodies are made by joining together two substantially symmetrical parts, each one of which is formed by a plurality of circular, coplanar, concentric, open grooves that are integrally connected to each other. The assemblies are secured against their respective drum bases by means of a plurality of brackets, which are provided on the outer surface of the drum and are capable of mutually engaging respective zones of the outer edge of the assemblies.
