VEHICULAR LIGHTING FIXTURE

PROBLEM TO BE SOLVED: To provide a technology which improves designability of a vehicular lighting fixture.SOLUTION: A vehicular lighting fixture includes: a light source; and a lighting fixture component part having a body part 32 made of a translucent material and arranged between the light source and an outer cover. The lighting fixture component part has: a first surface 30b facing outside of the lighting fixture; and a second surface 30c which is at the back of the first surface 30b. The first surface 30b has: a first light reflection surface 30b1 for reflecting the light from the outside of the lighting fixture; and a first light transmission surface 30b2 for transmitting the light from the outside of the lighting fixture. The second surface 30c has a second light reflection surface 30c1 for reflecting the light which has entered the lighting fixture component part via the first light transmission surface 30b2 from the outside of the lighting fixture toward the outside of the lighting fixture. The second light reflection surface 30c1 has an inclined part 36 for reflecting one part of the light which has entered the lighting fixture component part toward a boundary region BR between the first light reflection surface 30b1 and the first light transmission surface 30b2.SELECTED DRAWING: Figure 2 【課題】車両用灯具の意匠性を向上させる技術を提供する。【解決手段】車両用灯具は、光源と、透光性材料で構成される本体部３２を有し、光源とアウターカバーとの間に配置される灯具構成部品とを備える。灯具構成部品は、灯具外側を向く第１表面３０ｂと、第１表面３０ｂに背向する第２表面３０ｃとを有する。第１表面３０ｂは、灯具外からの光を反射する第１光反射面３０ｂ１と灯具外からの光を透過させる第１光透過面３０ｂ２とを有する。第２表面３０ｃは、灯具外から第１光透過面３０ｂ２を介して灯具構成部品内に入射した光を灯具外側に向けて反射する第２光反射面３０ｃ１を有する。第２光反射面３０ｃ１は、灯具構成部品内に入射した光の一部を第１光反射面３０ｂ１と第１光透過面３０ｂ２との境界領域ＢＲに向けて反射する傾斜部３６を有する。【選択図】図２
