A sealing member 144 may be disposed in the open portion of the housing 141 to seal the oil.

In one embodiment, the cover 142 may be coupled to the housing 141 and the sealing member 144, respectively. An opening into which the rod 130 is inserted may be formed in the cover 142. The cover 142 may include a third flange 143 formed in a peripheral area of the opening. The variable damper 140 may be fixed to the vertical frame 113 through the third flange 143.

In one embodiment, the coil (C) may interact with the magnet (M) included in the end of the rod (130). For example, when a voltage is applied to the coil C and a current flows, an attractive or repulsive force may be formed between the coil C and the magnet M. At this time, the repulsive force can attenuate the vibration and movement of the water tank 120 and the rod 130. That is, the variable damper 140 can provide additional damping force using the coil C in addition to the damping force provided by the oil.

Referring to FIG. 7 , in one embodiment, the control module 170 may apply a voltage to the coil C to generate a repulsive force between the coil C and the magnet M. In one embodiment, the control module 170 may adjust the damping force of the variable damper 140 based on the water level value of the water tank 120 obtained from the water level sensor 150. For example, when the amount of water filled in the water tank 120 is large, the control module 170 flows more current to the coil (C) to increase the repulsive force between the magnet (M) and the coil (C). You can. For another example, when the water filled in the water tank 120 is exhausted or there is little water, the control module 170 flows less current to the coil (C), thereby reducing the gap between the magnet (M) and the coil (C). Repulsion force can be reduced.
