Abstract
A washing machine includes a casing constituting the appearance, a support bar having one end connected to the casing and a suspension for connecting the other end of the support bar to the outer tub so as to suspend the outer tub within the casing, and for absorbing vibrations from the outer tub. The suspension includes an air cap through which the second end of the support bar passes. The air cab is installed on the outer circumference of the outer tub and moves along the support bar according to vibrations from the outer tub. A first friction member fitted on the support bar and disposed within the air cap to contact the inner surface of the air cap. A second friction member contacts the support bar and generates greater frictional force with the support bar than the force generated between the first friction member and the inner surface of the air cap to effectively decrease vibrations.
