Abstract
A washing machine having a dual damping structure can effectively prevent undesirable vibration of an outer tub by lowering the center of gravity of outer tub depending on a quantity of washing objects to stabilize the outer tub. A first damping part having a cap and a first spring is installed on the other end of a supporting rod, and dampens longitudinal vibration of the supporting rod. A second damping part having a slider and a second spring is integrally formed on a lower periphery of the outer tub. Also, there is provided a connecting means connecting the first damping part with the second damping part so as to transmit the vibration of the second damping part into the first damping part.
