<P>PROBLEM TO BE SOLVED: To provide a washing machine capable of restraining vibration. <P>SOLUTION: A cushioning member 32 of a liquid balancer 30 of the washing machine 1 is fixed onto an inner wall face 311a of a container 31. A movable member 3412 blocks the cushioning member 32 from a liquid moving in an inside of the container 31, when the movable member 3412 is energized toward an inner wall face 312a by a spring 3413. The cushioning member 32 is deformed by the liquid imparted with a centrifugal force. A specific gravity of the liquid in a storage member 321 of the cushioning member 32 is lower than a specific gravity of the liquid in the container 31. A level of a force for energizing the movable member 3412 toward the inner wall face 312a by the spring 3413 is lower than a level of the centrifugal force imparted to the spring 3413 when the liquid balancer 30 is rotated at a rotational speed within a range from a primary resonance frequency of a system constituted of a rotary drum 20, a water vessel 40, a driving part 50 and the liquid balancer 30, or more, up to a half or less of a secondary resonance frequency of the system. <P>COPYRIGHT: (C)2011,JPO&INPIT |
