Abstract: A washing machine includes a cabinet, a tub disposed inside the cabinet, and a rotating tub rotatably disposed inside the tub. A suspension device connects the tub to the cabinet such that the tub is supported by the cabinet, and a vibration reduction apparatus is coupled between the tub and the suspension device to reduce vibration of the tub according to rotation of the rotating tub. The vibration reduction apparatus includes a first rod and a second rod rotatably coupled to the first rod.

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.
