Disclosed herein is a washing machine. A stator is mounted at the inside surface of a tub, a spider is mounted at a drum, a rotor is mounted at the spider such that the rotor is rotated by the stator, and a support shaft is mounted at the spider for supporting the drum, the rotor, and the spider. Consequently, the capacities of the drum and the tub are increased as compared with the case that the stator and the rotor are mounted at the rear of the tub, and therefore, washing capacity of the washing machine is greatly increased.
