Abstract: A vibration limiter of a washing machine is disclosed. The vibration limiter includes a housing installed at one of a cabinet and a tub, a contact plate disposed within the housing such that the contact plate comes into contact with the other of the cabinet and the tub when the tub vibrates, a spring for elastically supporting the contact plate, a rotating member rotatable by at least one of the spring and the contact plate, and an oil damper engaged with the rotating member. The oil damper complementarily acts with the spring, to effectively absorb vibration. Accordingly, it is possible to reduce the size of the spring and to secure enhanced reliability even after prolonged use.

Abstract: A laundry treatment apparatus in which as an outer tub vibrates, a piston and a cylinder are relatively moved. When as the outer tub vibrates, the piston and the cylinder move relative to each other and a frictional member provides a frictional force between itself and the other one to attenuate vertical vibration of the outer tub. In particular, the piston and the cylinder are prevented from being separated from each other in the laundry treatment apparatus.
