PURPOSE: A sealing structure of a drain motor for a washing machine is provided to rotate a synchronous motor part regardless of the interference of the foreign material and to prevent the abrasion between a rotary shaft and a bearing part. CONSTITUTION: A sealing structure of a drain motor for a washing machine comprises a synchronous motor part(100), a bearing part(200), a ceiling, a gasket part(400), and a gasket holder(500). The ceiling is inserted between a rotary shaft and the bearing part. The cross section of the ceiling is curved shape. The ceiling is shrunk toward the central part of the rotary shaft by the water pressure of the washing water. The bearing part is inserted in the central part of the gasket part. The gasket is inserted in the center of the gasket holder. The impeller part is combined in outer circumference of the gasket holder. |
