The fastening hole 125 of the cover is preferably formed to a depth that the head portion of the fastening bolt 126 does not protrude to the outside. This is to prevent the laundry from being damaged such as lint generated in the laundry by the fastening bolt 126.

At least one guide hole 116 is formed at both sides of the fixing member 101 along a length direction, and guides are inserted into the guide holes 116 of the fixing member 101 at both sides of the cover 120. More preferably, the projection 127 is formed.

In this case, the guide protrusion 127 of the cover 120 is fitted to the rear edge of the guide hole 116 of the fixing member 101 when sliding the cover 120 to the rear side as shown in FIG. It is bent to the rear side of the cover 120. The guide protrusion 127 prevents the thin and long formed cover 120 from being bent or deformed upward and guides the installation position of the cover 120.

On the other hand, when the cover 120 is applied to the sliding structure fixed to the front side, the guide protrusion 127 will be bent to the front side of the cover 120.

The guide protrusion 127 may be formed in an appropriate number in consideration of the length, width, and thickness of the cover 120.

The boss 128 is formed in the fastening hole 125 of the cover 120 as illustrated in FIG. 5, and the boss 128 of the cover member 120 corresponds to the boss 128 of the cover 120 at one end of the rear side of the fixing member 101. 117 is formed.

A process of fastening the lift in the drum washing machine configured as described above will be described.

When the supporter 130 is fastened to the bottom surface of the cover 120, the first and second hooks 132 and 133 of the supporter are inserted into and fastened to the first and second guides 122 and 123 of the cover. In this case, since the gate 129 of the cover is located outside the supporter by avoiding the portion where the supporter 130 is inserted, the supporter may be fastened without removing the gate 129. Accordingly, the supporter can be fastened to the cover easily.

Thus, the cover 120 to which the supporter 130 is fastened is slidingly fastened to the upper portion of the fixing member 110. At this time, the guide protrusion 127 is inserted into the guide hole 116, and then fastening the fastening bolt 126 to the fastening hole 125 of the cover. Accordingly, the fastening ball holder is detachably fastened to the fixing member.

Next, the process of separating the washing ball holder is the reverse of the above-described fastening order, a description thereof will be omitted.

As described above, the drum washing machine according to the present invention has the following effects.

The gate of the cover protrudes from a portion which avoids mutual interference when fastening the supporter and the fixing member. Therefore, in order to assemble the parts of the lift, the gate must be removed, and since the separate processing is not necessary to remove the marks from which the gate has been removed, the assembly process of the lift is advantageous and the assembly time is reduced.
