Abstract
There is disclosed a device for displaying the operation of a knob that is used for an automobile heater control unit, for example. The device has a frame in which a slider is mounted so as to be horizontally slidable. The knob is fixed to one end of the slider. A first light-conducting body that can be illuminated by a lamp to display the operation of the knob is so formed as to surround the slider and the knob. A second light-conducting body that can be illuminated by a second lamp to display the position of the knob is so mounted that the end of this body is located within the outer end surface of the knob. That is, the first light-conducting body is located around the second conducting body.
