PURPOSE: A washing machine is provided to improve washing efficiency by restricting or removing bubbles efficiently with arranging a pumping blade around the washing shaft and forming a one-way bearing between the pumping blade and the washing shaft. CONSTITUTION: A washing machine comprises a casing(11) forming the storage space; an outer tub(21) arranged in the casing; an inner tub(31) rotated inside the outer tub; a hollow dehydrating shaft(33) extended downward in the lower part of the inner tub; a washing shaft(35) arranged in the dehydrating shaft and rotated relatively to the dehydrating shaft; a driving motor(38) rotating the washing shaft; a washboard(51) spaced from the lower part of the inner tub and integrally rotated with the washing shaft; a pumping blade(61) arranged in the lower part of the washboard and composed of plural blades arranged radially to the washing shaft; and a one-way bearing(71) inserted between the pumping blade and the washing shaft along the radial direction of the washing shaft. |
