To provide a turn signal lamp capable of suppressing an increase in size while improving a notification function.SOLUTION: A turn signal lamp 1 comprises a plurality of lighting fixture units 20a, 20b and 20c which have light sources 30a, 30b and 30c and lenses 40a, 40b and 40c having an incidence part 40i, a first internal reflection part 51, a first emission part 61, and a second emission part 62. Light emitted by the light sources 30a, 30b and 30c impinges on the incidence part 40i, the first emission part 61 emits part of the light in a direction not parallel with the perpendicular direction, and the first internal reflection part 51 internally reflects the other part of the light toward the second emission part 62, which emits at least part of the light internally reflected by the first internal reflection part 51 toward a road surface. The plurality of lighting fixture units 20a, 20b and 20c draw predetermined images 71a, 71b and 71c on the road surface, respectively, those drawn images 71a, 71b and 71c being parallelized as they go away from the vehicle.SELECTED DRAWING: Figure 9

    【課題】 報知機能を向上しつつ大型化を抑制し得るターンシグナルランプを提供する。【解決手段】 ターンシグナルランプ1は、光源30a,30b,30cと、入射部40i、第1内部反射部51、第1出射部61、及び第2出射部62を有するレンズ40a,40b,40cと、を有する複数の灯具ユニット20a,20b,20cを備え、入射部40iには光源30a,30b,30cから出射する光が入射し、第1出射部61は、光の一部を鉛直方向と非平行な方向に出射し、第1内部反射部51は、光の他の一部を第2出射部62に向けて内部反射し、第2出射部62は、第1内部反射部51で内部反射した光の少なくとも一部を路面に向けて出射し、複数の灯具ユニット20a,20b,20cのそれぞれは、路面に所定の描画像71a,71b,71cを描画し、これら路面に描画される描画像71a,71b,71cは、車両から遠ざかる方向に並列される。【選択図】 図9
