PURPOSE: Pulsator structure is provided to prevent a twisting of the laundry by changing washing force according to a rotating direction of a rotary wheel. CONSTITUTION: A pulsator(70) comprises many rotary wheels(72) around a shaft inserting slot(71). The rotary wheel(72) comprises an inclined inner face(72B) and an inclined outer face by slantingly twisting. The rotary wheels(72) are formed integrally not to be symmetrical each other. In a normal rotation, a general heart stream is formed. In a reverse rotation, an inverse stream is formed to lift the laundry by crashing washing water inside the pulsator. Thereby, a twisting of the laundry is prevented and the washing efficiency is increased.
