A knob apparatus for a controller is provided to prevent damage to a connection section of a knob and an encoder due to vibration and an impact applied to the knob apparatus. A knob apparatus of a controller includes a supporter(50), an encoder(40), a knob(30), and a holder(60). The supporter is mounted to a substrate of the controller. The encoder is installed between the supporter and the substrate so that one end thereof can pass through the front surface of the supporter. The knob is rotatably installed on the front surface of the supporter so that a connection protrusion(34) connected to an end of the encoder protrudes from the rear surface thereof. The holder is integrally formed with the supporter so as to rotatably support the connection protrusion of the knob, wherein the holder surrounds the end of the encoder. |
