PROBLEM TO BE SOLVED: To provide a pointer instrument in which a light source is arranged behind a pointer formed with a material having light conductivity and the pointer is illuminated by injecting light from the light source thereto, with which it is possible to suppress the leakage of light for illuminating the pointer.SOLUTION: Between the base part 32 of a 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 with a material having light conductivity, and has an annular light-receiving part 61 at a position facing the light source 8 at a radially shifted position from an axis of rotation L1 of the pointer 3. The light guide part 6 is formed in such a shape that the light received by a light receiving part 61 is converged at a center position where the axis of rotation L1 is located. The light guide part 6 has a protrusion 63 at a center position that protrudes in the direction of the axis of rotation L1. A shading cover bulb 7 is provided so as to enclose the whole region of a skirt part 62 of the light guide part 6 as a two-color molded article with the light guide part 6. A shading cover bulb 5 enclosing the rear 33b of a base part 32, a boss part 34 of the pointer 3 and the protrusion 63 is provided.SELECTED DRAWING: Figure 2

    【課題】導光性を有する部材で形成された指針の背後に光源を配置して、その光源からの光を指針に入射することで指針を照明する指針計器において、指針を照明するための光の漏れ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、導光性を有する部材で形成され、指針3の回転軸線L1から径方向にずれた位置において光源8に対向する位置に環状の受光部61を有する。導光部6は、受光部61で受光した光を、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。導光部6は中央位置に回転軸線L1の方向に突出した突出部63を有する。導光部6のスカート部62の全範囲を取り囲むように遮光性のカバーバルブ7が導光部6との2色成形品として設けられる。基部32の背面33b、指針3のボス部34及び突出部63を取り囲む遮光性のカバーバルブ5が設けられる。【選択図】図2
