Abstract: A washing machine and a method for manufacturing the same are disclosed. A washing machine includes a casing that defines an outer appearance of the washing machine and an outer tub in the casing that is configured to receive water. A supporting rod is coupled with the casing, and a suspension is coupled with the outer tub, the supporting rod being inserted in the suspension. The suspension is configured to move bi-directionally along the supporting rod as the outer tub vibrates to mitigate vibration of the outer tub, and the suspension includes a frictional part configured to contact the supporting rod. The suspension is configured to apply a lubricating material to a portion of the supporting rod that is brought in contact, during the vibration of the outer tub, with the frictional part of the suspension.

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.
