VEHICULAR LIGHTING FIXTURE

PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture which enables uniform light emission.SOLUTION: A light guide body 5 includes: a first end surface 5a located on the side opposing to a plurality of light sources 2; a second end surface 5b located on the opposite side from the first end surface 5a; and a third end surface 5c and a fourth end surface 5d for connecting between the first end surface 5a and the second end surface 5b and located on the outside and inside in the vehicle width direction. The first and second end surfaces 5a, 5b are inclined, with respect to a travelling direction of light L which enters from the first end surface 5a and is guided toward the second end surface 5b, in the direction in which the outside retreats further than the inside in the vehicle width direction. The third and fourth end surfaces 5c, 5d are inclined at an angle which reflects light L1, L2 which has entered the third and fourth end surfaces 5c, 5d toward the second end surface 5b, and in the third end surface 5c, a distance connecting between the first end surface 5a and the second end surface 5b is shorter than that of the fourth end surface 5d.SELECTED DRAWING: Figure 4 【課題】より均一な発光を可能とした車両用灯具を提供する。【解決手段】導光体５は、複数の光源２と対向する側に位置する第１の端面５ａと、第１の端面５ａとは反対側に位置する第２の端面５ｂと、第１の端面５ａと第２の端面５ｂとの間を結ぶと共に車両幅方向の外側及び内側に位置する第３の端面５ｃ及び第４の端面５ｄとを有し、第１及び第２の端面５ａ，５ｂは、第１の端面５ａから入射して第２の端面５ｂに向かって導光される光Ｌの進行方向に対して、車両幅方向の内側よりも外側が後退する方向に向かって傾斜しており、第３及び第４の端面５ｃ，５ｄは、当該第３及び第４の端面５ｃ，５ｄに入射した光Ｌ１，Ｌ２を第２の端面５ｂに向けて反射する角度で傾斜しており、なお且つ、第３の端面５ｃは、第４の端面５ｄよりも第１の端面５ａと第２の端面５ｂとの間を結ぶ距離が短い。【選択図】図４
