Abstract: A joint, a knob assembly, and an appliance having a joint and a knob assembly are provided. The joint may include a housing, a first shaft support, a second shaft support, and a coupling shaft. A slot having a predetermined width extending in a circumferential direction of the housing and a predetermined length extending in a longitudinal direction of the housing may be formed in the housing. The coupling shaft provided in the second support may include a rotary shaft rotatably inserted into the slot. A stopper may be formed to protrude from an outside of the rotary shaft, and a position of the stopper inside the slot may be changed according to rotation of the rotating shaft. The stopper may be provided in the slot so that the stopper interferes with an inner wall of the housing formed by the slot at a predetermined position.
