A washing machine including a suspension to support an outer tub so as to absorb vibrations of the outer tub. The suspension includes an outer tub supporter disposed so as to be movable along a support rod, an elastic member to elastically support the outer tub supporter, a first friction unit to apply frictional force between the first friction unit and the support rod, and a second friction unit disposed above the first friction unit and movable along the support rod, the second friction unit applying frictional force between the second friction unit and the support rod, the second friction unit being displaceable relative to the outer tub supporter within a space delimited by the outer tub supporter.
