Abstract
A drum type washing machine includes a housing; a spin tub rotatable by a driving motor through a rotating shaft; a balancer installed at a rear section of the spin tub; a shaft flange including a hub section to fixedly install the rotating shaft and a plurality of arm sections extending radially outward from the hub section and mounted to the spin tub so as to uniformly transfer the rotational force to the spin tub; and a rear cover provided on the rear section of the spin tub. The balancer is disposed adjacent to the rear cover and the shaft flange such that the first annular-shaped member contacts the shaft flange and the second annular-shaped member contacts the rear cover.
