Abstract: A laundry treatment apparatus includes a case, a tub configured to accommodate washing water, a drum installed inside the tub and configured to accommodate laundry, a pulsator installed inside the drum and configured to rotate by receiving driving force, and a driver configured to provide driving force for rotating the drum and the pulsator. The driver includes a driving motor including a stator and a rotor, a bearing housing installed at a lower portion of the tub, a dewatering shaft having a lower end disposed adjacent to the rotor and an upper end connected to the drum, a coupler configured to selectively connect the dewatering shaft to the rotor while lifting along an outer circumferential surface of the lower end of the dewatering shaft, a washing shaft positioned inside the dewatering shaft, and an anti-friction member inserted between the dewatering shaft and the washing shaft.
