PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture which achieves uniformity of luminance distribution, which includes a light guide body whose production cost is cheap and in which the degree of freedom is high when being mounted on a vehicle.SOLUTION: In a light guide body 10 in which a first light guide part 20 and a second light guide part 40 are arranged in an L-shape, at the first light guide part 20, a light guide lens part 25 whose opposing surfaces are a light reflection surface 26 and a light emission surface 27 and a columnar light guide part 30 are disposed side by side in parallel at a predetermined interval, and at the second light guide part 40, a light guide lens part 45 whose opposing surfaces are a light reflection surface 46 and a light emission surface 47 and a columnar light guide part 50 are disposed side by side in parallel at a predetermined interval, and light sources 2, 3 are arranged in the vicinity of end surfaces of the light guide parts 20, 40 respectively. Thereby, in the light guide lens part 25, emission light L1a from the light source 2 and emission light L2b from the light source 3 guided in the light guide part 50 are introduced, and in the light guide lens part 45, the emission light L2a from the light source 3 and the emission light L1b from the light source 2 guided in the light guide part 30 are introduced.SELECTED DRAWING: Figure 4

    【課題】輝度分布の均一化が図られると共に製造コストが安価な導光体を備えて車両への取り付け自由度が高い車両用灯具を提供することにある。【解決手段】第1導光部20と第2導光部40をL字状に配置した導光体10において、第1導光部20に、対向面を光反射面26及び光出射面27とする導光レンズ部25と円柱状の導光ガイド部30とを所定の間隔で平行に並設し、第2導光部40に、対向面を光反射面46及び光出射面47とする導光レンズ部45と円柱状の導光ガイド部50とを所定の間隔で平行に並設し、導光部20、40の夫々の端面近傍に光源2、3を配置した。これにより、導光レンズ部25には光源2からの出射光L1aと導光ガイド部50を導光された光源3からの出射光L2bが導入され、導光レンズ部45には光源3からの出射光L2aと導光ガイド部30を導光された光源2からの出射光L1bが導入される。【選択図】図4
