An operating device includes: an operating member operable by a user; a rotation shaft having an end portion provided with the operating member; a first bearing supporting a first portion of the rotation shaft; and a second bearing supporting a second portion of the rotation shaft. The second portion is located nearer to the operating member than the first portion in an axial direction of the rotation shaft.

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.

A knob assembly includes a front panel, a knob located at a front side of the front panel and configured to rotate based on operation by a user, a knob shaft that is coupled to the knob and that extends through the front panel, a supporting pipe that receives the knob shaft and that supports the knob shaft, the supporting pipe being configured to maintain a position relative to the front panel, a valve configured to control supply of gas to the appliance, a valve shaft connected to the valve and configured to control the valve to adjust a flow rate of gas based on rotation of the valve shaft, and a joint that couples the knob shaft to the valve shaft and that is configured to transfer at least one of a rotational motion or a linear motion of the knob shaft to the valve shaft.

A user interface includes a front panel that has an exterior surface and an interior surface. A flange outwardly extends from the exterior surface and defines a notch. A receiving body extends from the interior surface of the front panel that is proximate the flange. A receiving body has an angled edge and defines a drainage channel that extends through a portion of the notch that is defined by the flange.
