The invention provides a vehicle lighting fixture which enables a light guide body to emit uniform and banded light and improves the light utilization rate of the light guide body. The vehicle lighting fixture is characterized in that emergent light from a light-emitting diode (30) enters a right end face (20a) relative to the light guide body (20), is totally reflected by a plurality of reflection members (20s) formed on a rear side part (20c) and is emitted to the front from a front side part (20d). The light guide body (20) is configured to extend along a horizontal direction cross with an anteroposterior direction of the lighting fixture with a basically fixed wall thickness, so that the plurality of reflection members (20s) are formed densely in the length direction of the light guide body (20) formed as a long light guide pillar and enable the light guide body (20) to emit uniform and banded light. A lens part (20e) formed on the right end face (20a) of the light guide (20) for enabling the emergent light from the light-emitting diode (30) to enter an incident plane in a manner of being roughly parallel to a horizontal plane is capable of basically preventing diffusion of the emergent light of the light guide body (20) in the up-and-down direction, thereby improving the light utilization rate of the light guide body. |
