Abstract
A clothes treating apparatus includes: a cabinet; a tub positioned inside the cabinet; a drum configured to rotate inside the tub; and a damper coupled to the cabinet and the tub and configured to reduce vibrations of the tub according to a rotation of the drum. The damper includes: a piston; a cylinder forming an inside space in which the piston is movable, the cylinder including a yoke and a bobbin positioned at one side of the yoke; and a friction member positioned between an outer surface of the piston and an inner surface of the cylinder and including a magneto-rheological fluid of which viscosity changes according to a magnetic field. A thickness of the friction member positioned between the piston and the bobbin is smaller than a thickness of the friction member positioned between the piston and the yoke.
