PURPOSE: A drainage pump for a washing machine which increase centrifugal force when a synchronous motor part rotates is provided to reduce noise generated in the bidirectional rotation of the synchronous motor part by making a stopper and a rotary shaft tap with a rubber or elastic material. CONSTITUTION: A drainage pump for a washing machine comprises a synchronous motor part(100), a rotary shaft tap, an impeller(300), and an eccentric member(400). The rotary shaft tap is made of a rubber or elastic material. One side of the rotary shaft tap is expanded in the radial direction of the rotary shaft. An impeller tap is projected one inside of the impeller. The impeller tap restricts the rotational motion of the rotary shaft tap. The center of gravity of an eccentric body is eccentric in order to increase the rotation power and speed of the synchronous motor part. |
