PROBLEM TO BE SOLVED: To provide a pointer instrument in which a transmission part for allowing light received by a base part to pass through is provided at the top of a cap covering the base part of a pointer, with which it is possible to suppress the occurrence of unevenness in luminance between portions of the transmission part.SOLUTION: A ring part 304 is formed at the top of a base part 32 of a pointer 3. A cap 4 covering the base part 32 comprises a cap body 41 in which an opening hole 41c is formed at the top and an inside cover 42 for shutting up the opening hole 41c. The ring part 304 is provided in such a shape that it fits in a ring-shaped slit formed by the cap body 41 and the inside cover 42. Between a boss part 34 of the pointer 3 and a light source 8 is provided a light guide part 6 that is separate from the pointer 3. The light guide part 6 is formed in such a shape that light received by a light-receiving part 61 is converged at a center position where an axis of rotation L1 of the pointer 3 is located. At a center top position of the base part 32 is formed a reflection surface 37 for reflecting light in all directions around the axis of rotation L1. The ring part 304 is arranged radially outward of the reflection surface 37.SELECTED DRAWING: Figure 2

    【課題】指針の基部を覆うキャップの頂上部に、基部で受光した光を透過させる透過部を設けた指針計器において、透過部の部位間で輝度にばらつきが生じるのを抑制できる指針計器を提供する。【解決手段】指針3の基部32の上面にリング部304が形成される。基部32を覆うキャップ4は、頂上部に開口孔41cが形成されたキャップ本体41と、開口孔41cを塞ぐ内側カバー42とを有する。リング部304はキャップ本体41と内側カバー42とで形成されるリング状のスリットに嵌る形に設けられる。指針3のボス部34と光源8との間に指針3と別体の導光部6が設けられる。導光部6は受光部61で受光した光を指針3の回転軸線L1が位置する中央位置にて集束する形状に形成される。基部32の上面の中央位置には、回転軸線L1回りの全方向に光を反射させる反射面37が形成される。リング部304は反射面37より径方向外側に配置される。【選択図】図2
