Abstract
A front-loading washing machine includes a housing; a washing tub including one or more locking holes on a lateral side; and one or more lifters lifting up laundry based on spinning of the washing tub. The lifter includes a locking member passing through the locking hole, bent at an outside of the washing tub and extended in a spinning axis direction of the washing tub. The locking hole includes a first edge to which the locking member is locked to couple the lifter and the washing tub, and a second edge and a third edge adjacent to opposite ends of the first edge and surrounding the locking member to face with each other.
