PROBLEM TO BE SOLVED: To provide an on-vehicle analog timepiece assembling structure that can average luminance of portions to be illuminated as much as possible by indirectly illuminating pointers and the like.SOLUTION: An illumination light structure comprises: a movement; a circuit substrate 6; a light guide plate 8; a circular dial plate 9; and pointers 10 such as hour/minute hands. In the circuit substrate 6, an LED 7 is plurally arranged that radiates toward the light guide plate 8 with light, and the light guide 8 includes: an introduction part that introduces the light from the LED 7 to the light guide plate 8; and a ring-like protrusion part 8b that is positioned at a circumference of the dial plate 9, and protrudes frontward. In the dial plate 9, a non-transmission type not transmitting the light, and a transmission type transmitting the light are selectively installed, and when the LED 7 emits light, the light is introduced from the introduction part of the light guide plate 8 and is led out from the ring-like protrusion part 8b. Accordingly, the pointer 10 and the dial plate 9 are illuminated.SELECTED DRAWING: Figure 3 |
