Abstract
A drum-type washing machine includes a resin drum which is rotatably supported in a frame by a horizontal shaft. The resin drum includes a body portion molded out of a synthetic resin, and an end surface formed at one end of the body portion, the other end being open. A fluid balancer positioned at the open end of the body portion includes a hollow annular member and a predetermined amount of saltwater sealed therein. The drum diameter is increased from the one end to the other end by utilizing a taper or slope from a plastic molding process. Therefore, the wash in the drum, in operation, moves to the vicinity of the fluid balancer at the other end of the drum along the slope of the inner surface of the drum, thereby to produce a maximum balancing effect of the fluid balancer.
