Classification: CPC F | IPC F

Claim 7:
8. A vehicle light guide, comprising:
an incident surface on which light from a light source is incident;
a first reflective surface that has a first focus that positions on a front in a front-back direction in a vehicle-mounted state and internally reflects the light incident from the incident surface toward the first focus;
a second reflective surface which internally reflects a part of the light reflected by the first reflective surface toward the front in the front-back direction, wherein the first focus of the first reflective surface positions at an edge side on the front in the front-back direction of the second reflective surface;
a transmission surface which is provided in a stepped state from an edge side on a rear in the front-back direction of the second reflective surface toward an outer side of the light guide and transmits a part of the light reflected by the first reflective surface to the outer side of the light guide;
a re-incident surface which is provided in a stepped state from the edge side on the front in the front-back direction of the second reflective surface toward the outer side of the light guide to face the transmission surface such that the light transmitted from the transmission surface to the outer side of the light guide is re-incident; and
an emission surface which has a curved surface having a focus at a position which coincides or substantially coincides with the edge side on the front in the front-back direction of the second reflective surface, emits the light internally reflected by the first reflective surface and the second reflective surface and the light incident from the re-incident surface, and emits a light distribution pattern to a front of the vehicle.
