PROBLEM TO BE SOLVED: To provide a pointer illumination structure capable of suppressing light leakage without requiring other components such as dimming members by extending a light guide body to the inside of a pointer cap.SOLUTION: A pointer illumination structure of an indicator includes: a base plate 1; a translucent pointer 2 supported rotatably around a rotating shaft 23 as a rotation center; a pointer cap 3 engaged with the pointer 2; a light source 4 provided to the base plate 1; and a light guide body 5 for making the pointer 2 emit light by transmitting illumination light emitted from the light source 4 to the pointer 2. One end of the light guide body 5 extends to the inside of the pointer cap 3.

    【課題】導光体を指針キャップ内にまで延出させて用いることにより、調光部材のような別部材を必要とせずに光漏れを抑えることが可能な指針照明構造を提供する。【解決手段】指示計器の指針照明構造は、基板1と、回動軸23を回動中心として回動可能に軸支される透光性の指針2と、指針2に嵌合される指針キャップ3と、基板1に設けられる光源4と、光源4から射出される照明光を指針へ伝搬させて指針を発光させる導光体5と、を有し、導光体5の一端は、指針キャップ3内にまで延出することを特徴とする。【選択図】図1
