ABSTRACT:
Clothes washing machine, in particular of the household type, comprising a tub containing a perforated drum (1) which is formed by an outer cylindrical mantle, a rear plate and an open front wall and is supported by a spider journal, wherein the drum is molded as a single piece by a blow-molding process in which the outer cylindrical mantle of the drum is formed so as to create a plurality of trapezoidally shaped concave ribs (4). The drum has a peripheral rim (6) projecting from the outer portion, in particular from the front outer portion of the cylindrical mantle near the opening, so as to strengthen the structure and enable it to stand the highest expected load stresses. To the peripheral rim, appropriate extensions of the arms of the spider journal are fastened.
