To provide a lamp for a vehicle with excellent visibility.SOLUTION: A lamp 1 for a vehicle performs sequential display by sequentially lighting on or off three or more light sources, and comprises three or more light sources 15 aligned in a forward and backward direction of the vehicle, and a transparent material 20 for guiding the light from the light sources and emitting the light forward and backward of the vehicle. The transparent material is constituted by three or more split bodies in contact with each other on a boundary face 35, and has three or more incident elements respectively opposed to the light sources on the respective split bodies and making light emitted from the light sources into primary parallely light parallel to a direction orthogonal to an aligning direction of the light source, a reflection part 26 provided across the three or more split bodies and making the primary parallel light into secondary parallel light by inner-face reflection, and an emission face 29 extending in a horizontal direction of the vehicle and emitting the secondary parallel light. The boundary face includes a first boundary face 31 extending parallel to the primary parallel light. The first boundary face blocks an optical path of the primary parallel light corresponding to the three or more light sources.SELECTED DRAWING: Figure 3

    【課題】視覚性に優れた車両用灯具の提供を目的とする。【解決手段】車両用灯具1は、3以上の光源を順次点灯又は順次消灯させることでシーケンシャル表示する車両用灯具であって、車両の前後方向に沿って配列された3以上の光源15と、光源からの光を導光して車両の前方又は後方に出射する導光体20と、を備える。導光体は、境界面35において互いに接触する3以上の分割体から構成され、それぞれの分割体において光源にそれぞれ対向して設けられ光源から出射された光を光源の配列方向と直交する方向に平行な一次平行光とする3以上の入射素子と、3以上の分割体に跨って設けられ一次平行光を内面反射して二次平行光とする反射部26と、車両の左右方向に沿って延び二次平行光を出射する出射面29と、を有する。境界面は、一次平行光と平行に延びる第1の境界面31を含む。第1の境界面は、3以上の光源に対応する一次平行光の光路を区画する。【選択図】図3
