To provide a pointer type instrument device which uses a shading part of a pointer as a small diameter, and has high appearance merchantability.SOLUTION: A pointer type instrument device includes: a light source 2 mounted to a hard circuit board 1; a pointer drive part 3 mounted to the circuit board 1; a pointer 4 having an indication part 41 formed of a light-transmissive material and emitting light by guiding light from the light source 2, a pointer shaft part 43 engaged with the pointer drive part 3, a rotation base 42 connecting the indication part 41 to the pointer shaft part 43; and a number plate 5 disposed between the circuit board 1 and the indication part 41, and having an open hole 51 through which the pointer shaft part 43 penetrates. In the pointer shaft part 43, a diameter of a pointer hole opposing part 43a facing the open hole 51 is formed to be smaller than a diameter of a drive side shaft part 43b located at a pointer drive part 3 side of the pointer hole opposing part 43a.SELECTED DRAWING: Figure 2

    【課題】 指針の遮光部を小径とし、見栄えの商品性の高い指針式計器装置を提供する。【解決手段】 硬質の回路基板1に実装された光源2と、回路基板1に実装される指針駆動部3と、透光性材料から形成され光源2からの光を導光して発光する指示部41と、指針駆動部3と嵌合する指針軸部43と、指示部41と指針軸部43を接続する回転基部42と、を有する指針4と、回路基板1と指示部41の間に配置され、指針軸部43が貫通する貫通孔51と、を有する文字板5と、を備え、指針軸部43は、貫通孔51と対向する指針孔対向部43aの直径が、指針孔対向部43aよりも指針駆動部3側である駆動側軸部43bの直径よりも小さく形成される。【選択図】 図2
