ABSTRACT:
The present invention is configured so that one light emission source such as a light emitting diode is placed inside an operation knob in front of a light guiding piece or in a bearing of the operation knob. A light beam from the light emission source is emitted to the interior of the operation knob. A reflected indirect light irregularly reflected inside the operation knob is received by the light guiding piece located at a rear surface of the operation knob. The light guiding piece has a transmission and diffusion function. The light is then guided toward an outer periphery to illuminate the rear surface of the operation knob.
