PROBLEM TO BE SOLVED: To provide an assembling structure of an analogue timepiece on a vehicle which averages as much as possible the luminance of an irradiated place such as a pointer and avoids the leakage of light from the center part of the timepiece.SOLUTION: An assembling structure of an analogue timepiece on vehicle includes: a movement 5; a circuit board 6; a light guide plate 8; a center cap 12; and a dial plate 9 and a pointer 10. The circuit board 6 is arranged with a plurality of LEDs 7 for emitting light to the light guide plate 8. The light guide plate 8 includes: an introduction part for introducing light from the LEDs 7 to the light guide plate; and a ring-shaped protrusion 8b located in the circumferential edge of the dial plate 9 and protruding to the front. The dial plate 9 is selectively installed with a non-transmission type plate that does not transmit light and a transmission type plate that transmits light. The center cap 12 has a cylindrical part supported by externally fitting to a shaft of the pointer 10, and a flange part provided on the tip end thereof, and the dial plate 9 is located at the front side of this flange.SELECTED DRAWING: Figure 3
【課題】指針などの照明される箇所の輝度を可及的に平均化し且つ時計中央部からの光漏れを回避する車載用アナログ時計の組立構造を提供する。【解決手段】ムーブメント5、回路基板6、導光板8、中心キャップ12、文字板9及び指針10を備え、回路基板6には、導光板8に向けて光を照射するLED7を複数配置し、導光板8は、LED7からの光を当該導光板に導入する導入部と、文字板9の周縁に位置して正面側へ突出するリング状突出部8bを備え、文字板9は、光が通過しない無透過タイプのものと、光が通過する透過タイプのものとを択一的に設置し、中心キャップ12は、指針10のシャフトを外嵌して保持する筒状部と、その先端に設けられる鍔部とを備え、この鍔部の正面側に文字板9が位置する。【選択図】図3
