Summary:PROBLEM TO BE SOLVED: To solve a problem in a conventional lighting fixture for a vehicle that a slide metal mold may be used, as metal mold is complicated.SOLUTION: A light guide member has one incident surface 50, four emission surfaces 51, and a light guide portion 52. The light guide portion 52 is composed of a stem 53 provided with the incident surface 50, and four branch portions 54 respectively provided with the emission surfaces 51. The branch portions 54 are branched from the stem 53 along an advancing direction of the light incident from the incident surface 50. As a result, a metal mold can be simplified, and it becomes unnecessary to use a slide metal mold. 【課題】従来の車両用灯具では、金型が複雑となり、スライド金型を使用する場合がある。【解決手段】この発明は、１個の入射面５０と、４個の出射面５１と、導光部５２と、を備える。導光部５２は、入射面５０が設けられている幹部５３と、出射面５１がそれぞれ設けられている４本の枝部５４と、から構成されている。枝部５４は、入射面５０から入射した光の進行方向に沿って幹部５３から分岐されている。この結果、この発明は、金型が簡単となり、スライド金型を使用する場合がない。【選択図】 図２
