a tub;
a drum rotatably provided within the tub;
a cylinder supported by either a base or the tub;
a piston supported by either the tub or the base, the piston coupled with the cylinder to enable a relative reciprocating
motion, and comprising a magnetic force generating part which generates a magnetic force; and
a vibration-absorbing part provided within the cylinder, the vibration-absorbing part generating a frictional force by coming
into contact with an inner circumference of the cylinder,
wherein the vibration-absorbing part attaches to the piston to absorb a vibration transferred to the cylinder or the piston
when the magnetic force generating part generates the magnetic force.
