Vehicle light-guiding body and vehicle lighting unit

A vehicle light-guiding body comprising:

• an incidence surface on which light from a light source is incident;
• a first reflection surface that internally reflects the light incident from the incidence surface and converts the light into substantially parallel light;
• a second reflection surface that internally reflects the light reflected by the first reflection surface forward;
• a light blocking part that blocks a first portion of the light reflected by the second reflection surface, the first portion being light that reaches the light blocking part among the light reflected by the second reflection surface;
• an adjustment surface that extends forward from a front side end of the second reflection surface;
• a transmission surface that is provided in a state of extending upward in a down-up direction from a front side end of the adjustment surface and transmits a second portion of light reflected by the second reflection surface to a light-guiding body outer part, the second portion being light that reaches the transmission surface among the light reflected by the second reflection surface;
• a connection surface that connects an upper side end of the transmission surface and the light blocking part, and internally reflects forward a third portion of the light internally reflected by the second reflection surface-forward, the third portion being light that reaches the connection surface among the light reflected by the second reflection surface;
• a re-incidence surface that is disposed forward with respect to the transmission surface and downward with respect to the light blocking part, and on which the light transmitted from the transmission surface to the guiding body outer part is re-incident;
• and
• an emission surface that emits the light internally reflected by the second reflection surface and passing the light blocking part or passing above the light blocking part, and the light incident from the re-incidence surface to form a light distribution pattern in a front of a vehicle,
• wherein the light distribution pattern includes a main pattern in which a first pattern and a second pattern overlap each other at the front of the vehicle, the first pattern being formed by the light that is internally reflected by the second reflection surface, passes above the connection surface, passes the light blocking part or passes above the light blocking part, and is emitted from the emission surface, and the second pattern being formed by the light that is internally reflected by the second reflection surface, internally reflected by the connection surface, passes the light blocking part or passes above the light blocking part, and is emitted from the emission surface.
