A drum washing machine is provided to increase the intensity of a water tub backplane by controlling the formation of a concavo-convex in the partial domain of the water tub backplane. A drum washing machine comprises: a water tub(20) accommodating the water; a spin basket installed inside the water tub to be rotatable; and a driving motor installed at the water tub, having an axis of rotation installed at the spin basket through the back side center of the water tub. A concavo-convex(21) selectively is formed in the partial domain of the back side center of the water tub to increase the intensity. |
