PROBLEM TO BE SOLVED: To provide an assembly structure of an on-vehicle analog clock capable of homogenizing the luminance in a lit part such as a needle as much as possible.SOLUTION: The assembly structure includes a movement 5, a circuit board 6, a light guide plate 8, a number plate 9, and needles 10. On the circuit board 6, a plurality of LEDs 7 for radiating light toward the light guide plate 8 are disposed. The light guide plate 8 includes: an introduction part for introducing the light coming from the LEDs 7 to the light guide plate 8; a disk-like main body 8c; and a ring-like projection 8b that is located at a rim of the number plate 9 and projects toward the front side. The number plate 9 is fixed by a number plate presser 11 disposed inside the ring-like projection 8b, and the number plate presser 11 includes a plurality of bosses 11a in its lower part, and the bosses 11a are fixed to the disk-like main body 8c of the light guide plate 8.SELECTED DRAWING: Figure 3
