PURPOSE: A washing machine capable of preventing vibration which is generated when a rotary drum rotates is provided to equip with a vibration preventing unit in an upper end of the rotary drum to support the rotary drum. CONSTITUTION: A washing machine comprises a support unit(50) which supports a rotary drum(30) from a housing(10), a washing tub(20), the rotary drum, a drive unit(40) to be able to rotate. In an upper end of the washing tub and the rotary drum, a first flange unit(25) and a second flange unit(35) are formed to install the support unit. The first flange unit is extended to an outside based on a center of the washing tub. A structure of extending to an inner side of the rotary drum was applied to the second flange unit, but the second flange unit is able to be extended to the opposite direction. The support unit is installed between the washing tub and the rotary drum to prevent the rotary drum from vibrating. In this way, the inner side of the washing tub does not contact with the outside of the rotary drum when the rotary drum rotates. The support unit is comprised of the followings: a pressing plate(51) which is fixed on the upper side of the first flange unit prepared in the upper end of the washing tub, and formed in a ring shape along a columnar direction of the first flange unit; a ball plunger(53) fixed to a lower side of the pressing plate; a rail(55) which is prepared with a guide groove(55a) in which a ball plunger is inserted into a predetermined depth to prevent the rotary drum hitting the inner side of the washing tub by the vibration. The rail is fixed on the upper side of the second flange unit prepared in the upper end of the rotary drum, forms the ring shape along the columnar direction of the second flange unit, and guides a rotary track of the rotary drum when the rotary drum rotates. |
