PURPOSE:To resolve the problem that the effective luminescence area of a lighting fixture for a vehicle is decreased when the lighting fixture for a vehicle is formed into a shape rounded to the side face of a vehicle body. CONSTITUTION:Prism cuts 32c, 32d are applied on both faces on the radiation side 32a and the light source side 32b of an inner lens 3 at the position behind the light source 4 of the inner lens 3 so that the cut on one face corresponds to the cut on the other face. The light from the light source 4 is refracted in the radiation direction Z of a lighting fixture 1 for a vehicle by the cooperation of the prism cuts 32c, 32d on both faces of the inner lens 3, thus the light directed to the radiation direction from the position behind the light source 4 can be obtained. |
