PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture that has a translucent member with a direct light control part and a reflected light control part, and that performs light irradiation with relatively uniform lightness within a certain range having its center in a lighting fixture front direction.SOLUTION: A lens-shaped direct light control part which constitutes the center region of a translucent member is so configured that light intensity distributions Ah, Av of emitted light thereof have the highest light intensity I in directions first necessary angles αh, αv away from a lighting fixture front direction. A reflected light control part which constitutes the peripheral region of the translucent member, on the other hand, is so configured that light intensity distributions Bh, Bv of emitted light thereof have the highest light intensity I in the lighting fixture front direction. Then the light intensity distributions Ah, Av of the emitted light of the direct light control part and the light intensity distributions Bh, Bv of the emitted light from the reflected light control part are put together so as to obtain light intensity distributions Ah+Bh, Av+Bv which are relatively flat on the whole. |
