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.

Abstract: A washing machine includes a washing tub, a dewatering tub arranged rotatably in the washing tub, a housing to accommodate the washing tub, a suspension to suspend the washing tub from the housing substantially in a vertical direction, and a damper to connect the washing tub to the housing. The damper includes a translational damper to apply a damping force in a direction of translation, and a first rotational damper and a second rotational damper respectively connected to opposite ends of the translational damper while securing a degree of freedom substantially in the vertical direction of the translational damper, and to respectively apply the damping force in a rotating direction. The first rotational damper is arranged on a lower portion of the housing to be rotatable about a first rotary axis substantially in the vertical direction. The second rotational damper is arranged on a bottom of the washing tub to be rotatable about a second rotary axis substantially in the vertical direction.
