The present invention relates to a washing machine comprising: a rotary tub; a pulsator installed inside the rotary tub to be rotatable; a driving device which generates a rotational force; a dewatering axis which is cylindrically hollow shaped and connected to the rotary tub; a washing axis which penetrates through a dehydrating axis and connects the pulsator with the driving device; and a clutch device which delivers the rotational force from the washing axis to the dewatering axis in accordance to a rotational angle of the washing axis. As such, the washing machine delivers the rotational force of the washing axis to the dewatering axis in a more simple structure.
