ABSTRACT:
A cylinder is formed around a pointer shaft below a dial plate. A shade is projecting from an outer wall of a cylinder. The shade prevents inner figures on the dial plate from being illuminated by direct light from a light source at a back side of the dial plate. According to this structure, the inner figures and outer figures on the dial plate are illuminated uniformly.
