Laundry treating apparatus

A laundry treating apparatus comprising:

• a tub configured to receive washing water;
• a drum disposed in the tub and configured to receive laundry, the drum being configured to rotate about a rotation axis that extends in a front-rear direction of the laundry treating apparatus;
• and
• a lifter disposed on an inner circumferential surface of the drum and configured to rotate about the rotation axis based on rotation of the drum, the lifter comprising:
• a lifter frame installed on the inner circumferential surface of the drum and made of synthetic resin, the lifter frame having a frame sidewall that protrudes toward the rotation axis and extends in the front-rear direction, and
• a frame cover that is coupled to a lower portion of the lifter frame and protrudes radially inward from the lower portion of the lifter frame, the frame cover being made of metal,
• wherein the frame cover comprises:
• a cover upper plate spaced apart from the inner circumferential surface of the drum,
• a cover sidewall that extends from the cover upper plate to the lower portion of the lifter frame, the cover sidewall being spaced apart from the frame sidewall by a predetermined separation space configured to commutate the washing water between the cover sidewall and the frame sidewall, and
• a side protrusion that protrudes from an outer surface of the cover sidewall and defines a closed curve surrounding an entirety of an outer circumference of the cover sidewall in a plan view toward the inner circumferential surface of the drum.
