PROBLEM TO BE SOLVED: To provide a dial plate illumination device capable of suppressing the influence of leakage of light due to lifting of a dial plate.SOLUTION: A dial plate illumination device includes: a housing 22 in which an illumination chamber storing a light source 16 is formed in a shape hollowed toward a front surface of the housing 22; and a dial plate 15 which is arranged abutting on the front surface of the housing 22 in a manner to cover an illuminating opening 23 formed on a front side of the illumination chamber. The dial plate 15 has a light transmission part 24 illuminated by light 17 from the light source 16 at a position of the illuminating opening 23. A light leakage suppressing protrusion 41 for suppressing the leakage of the light 17 to a gap 31 generated between the housing 22 and the dial plate 15 is provided around at least a part of the illuminating opening 23 of the housing 22.SELECTED DRAWING: Figure 9A

    【課題】文字板の浮きなどによる漏光の影響を抑制し得る文字板照明装置を提供する。【解決手段】光源16が収容される照明室が手前面に凹設形成されたハウジング22と、このハウジング22の手前面に対し、照明室の手前側に形成された照明用開口部23を覆うように当接配置された文字板15と、を有し、文字板15が光源16からの光17によって照明される透光部24を照明用開口部23の位置に備えた文字板照明装置に関する。ハウジング22の照明用開口部23の少なくとも一部の周囲に、ハウジング22と文字板15との間に生じた隙間31への光17の漏れを抑制するための漏光抑制用突条部41を設けるようにする。【選択図】図9A
