設けたことを特徴とする計器の照明装置。[Scope of Claim for Utility Model Registration] A light guide plate is disposed behind the pointer in parallel with the pointer, and the light from the light source is guided from behind in the direction indicated by the pointer through the light guide plate to behind the base end of the pointer. In an instrument illumination device, the light from the light source is incident on the base end of the pointer through a reflective surface formed by a notch provided in the pointer, and the light is guided to the tip of the pointer by reflection at the base end of the pointer, making the entire pointer shine. At the tip of the light guide plate, there is a first reflecting surface that bends the light introduced into the light guide plate laterally along the light guide plate surface, and the light from the first reflecting surface is redirected toward the rear end of the light guide plate. An illumination device for an instrument, characterized in that it is provided with a second reflective surface that bends the light toward the base end of the pointer, and the notch that bends the light from the second reflective surface toward the proximal end of the pointer.
