FIELD: domestic electronic appliances. SUBSTANCE: washing-and-wringing machine has perforated internal tumbler coaxially mounted for rotation in external tumbler, drive, bearing unit with flange, and set of hangers. Set incorporates at least three hangers and bearing unit flange. Each hanger has case fastened to external tumbler and provided with shell installed inside tumbler; cone groove bordered by cylindrical surface and axial hole are made in shell bottom. Adjusting lid is mounted above shell and flexible members, inside the latter. Flange is provided with holes coaxial to respective axial holes in shell bottom of each hanger and radial conical grooves opposing similar ones, in shell bottom. All cone grooves and holes are centered relative to each other and contact each other through centering members in the form of small balls arranged inbetween with part of their sphere placed in holes for locking in them and for limited displacement through cone surfaces of respective cone grooves. EFFECT: improved reliability due to holding both tumblers in coaxial positions; reduced unbalance-caused thrusts on frame and external tumbler. 6 dwg
