Classification: CPC F  G | IPC F

Claim 0:
1. A vehicular light guiding body, comprising:
a plurality of incidence surfaces on which light from a light source is incident;
a plurality of first reflection surfaces that internally reflects the light incident from the incidence surface and converts the light into substantially parallel light;
a plurality of second reflection surfaces that has a shape based on a paraboloid of revolution which reflects the substantially parallel light from the first reflection surface into predetermined pattern light toward a focus point;
a light blocking part that blocks a portion of the predetermined pattern light reflected by the second reflection surface; and
an emission surface that emits the light internally reflected by the second reflection surfaces to pass through the light blocking part, and projects a headlight pattern toward a front of a vehicle,
wherein the plurality of first reflection surfaces and the second reflection surfaces are provided so as to correspond to each of the incidence surfaces, and
wherein a first one of the plurality of the second reflection surfaces includes a condensing pattern forming surface that internally reflects the substantially parallel light such that the substantially parallel light passes through the focus point and a vicinity of the focus point, and
a second one of the plurality of the second reflection surfaces includes a diffusion pattern forming surface that internally reflects the substantially parallel light such that the substantially parallel light passes through a position shifted to an outer side in a horizontal direction in an onboard state with respect to the focus point including the focus point.
