ABSTRACT:
A clothes washing machine has an external casing, a tub suspended in the external casing, and a spin basket rotatably installed in the tub and accommodating laundry. A damper includes a first member installed at the lower end of the tub which can wobble together with the tub, and a second member for attenuating vibration transferred to the tub by a mutual action with respect to the first member. Nonlinear and irregular vibration transferred to the tub during a rotational movement of the spin basket can be effectively attenuated, to reduce noise of the washing machine and perform a more stable washing cycle operation.
