ABSTRACT:
There is provided a vehicular display device in which a dial and a pointer are made to glow by a single light source other than a cold-cathode tube to reduce costs. The vehicular display device includes a dial and a disk pointer located at an opening of the dial. A movement having a decentered rotation shaft is mounted on the rear side of the disk pointer, and five bulb light sources are arranged around the movement. A first conical reflector for reflecting and guiding light from the light sources to the disk pointer is disposed between the light sources and the movement. Furthermore, a second reflector having reflecting curved surfaces for respectively guiding light from the light sources to the first reflector is disposed outside the light sources.
