Abstract
A drum-type washing machine, having a plurality of lifts installed on an inner circumferential surface of a drum, enables improved washing performance by providing friction plates on the inclined sides of each lift to increase a frictional force between the lift and laundry. Each lift includes a pair of inclined sides, disposed in opposition to each other to form a shape having a regular trapezoidal cross-section, for lifting laundry; and a pair of friction plates, consisting of a pair of opposing surfaces respectively provided on each inclined side and having a multitude of protuberances formed on both faces, to increase a frictional force with respect to the laundry.
