Abstract A suspension apparatus of a washing machine which supports a washing tub in a suspended state in a casing of the washing machine is disclosed. The suspension apparatus includes suspension rods supporting the washing tub in the casing in a suspended state, damper bases installed at the lower ends of the suspension rods, damping force changing members fitted around the suspension rods so as to be compressed according to the variations in load of the washing tub and change the damping force, and elastic members installed between the damping force changing members and the damper bases. Since the damping force of the suspension apparatus is changed according to a washing load generated by the washing tub during the operation of the washing machine, vibrations and noises of the washing tub can be minimized.
