PURPOSE: A washing machine driving device is provided to respectively rotate a washing tub and a pulsator for improving the washing efficiency while reducing the required parts. CONSTITUTION: A washing machine driving device includes upper and lower housings(41,42) mounted at upper and lower parts in an outer casing, an outer tub(43) fixed to the housings, a hollow dehydration shaft(46) rotatably coupled in the housings via upper and lower bearings(44,45), a washing tub(47) coupled at an upper part of the dehydration shaft, a washing shaft(49) rotatably mounted in the hollow dehydration shaft via one-way bearing(48), a pulsator(50) integrally fixed to an upper part of the washing tub, a motor rotator(51) coupled at a lower part of the washing shaft, and a motor stator(52) fixed to the lower housing. |
