To suppress the attenuation of light of a light source and constitute an inexpensive light-emitting indicator in a simple structure by forming the shaft of a rotator of a meter and the indicator of the meter out of a light- transmitting member and connecting the shaft and the indicator light-guidably.
The shaft 1 for a rotor and the indicator 2 of a gauge are formed out of the same medium and connected to communicate therebetween light-guidably. The light from a light source 3 is projected to one end of the shaft 1. The incident light from the light surface 3 comes outside through the shaft 1 and indicator 2, and therefore the indicator 2 appears as if it emitted light. Since the shaft 1 and indicator 2 are of the same light-guidable medium and the light is projected once from the light source 3 to the lower end face of the shaft 1, the light is never attenuated. In this constitution, the indicator 2 is changed to seven colors depending on a vehicle velocity, enabling a driver to recognize the vehicle velocity through the sense of color. The indicator can be designed to be economic and compact with complicate electric parts eliminated.
