发明名称 VEHICLE GAUGE
摘要 PROBLEM TO BE SOLVED: To provide a vehicle gauge capable of further suppressing the luminance unevenness of an index region.SOLUTION: The vehicle gauge includes a display panel 20 having an index region P, a plurality of light sources 40 arrayed on the rear side of an inner peripheral side region I of the index region P to illuminate the index region P, and a light guide 50 disposed between the display panel 20 and each of the light sources 40 to guide light from each of the light sources 40 to the display panel 20. The light guide 50 includes a plurality of light guide structures 51 arrayed in a rotational direction R. Each of the light guide structures 51 includes an incident part 52 into which light from a corresponding light source 40 enters, a first reflection part 53 for reflecting the light having entered into the incident part 52 toward the rear part of the index region P, and a second reflection part 54 for reflecting the light reflected by the first reflection part 53 to the index region P. The second reflection part 54 includes an inclined plane 55 inclined more to the front index region P farther from the first reflection part 53, and a plurality of dots 56 forming irregular patterns on the inclined plane 55.
