Abstract
A laundry treating apparatus is provided. The laundry treating apparatus includes a cabinet, a drum accommodated in the cabinet, a tub accommodating the drum, and a dynamic absorber provided to absorb oscillation of the cabinet. The dynamic absorber includes a support plate coupled to the cabinet, a first moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet, and a second moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet. A support comes into line or point contact with a bottom surface of the first moving mass so that the first moving mass has reduced attenuation ratio in comparison to the second moving mass.
