Vehicle lamp

A lens body, comprising:

• a first lens unit configured to form a first light distribution pattern which includes a first cut-off line;
• and
• a second lens unit configured to form a second light distribution pattern which includes a second cut-off line, wherein
• the first lens unit is a lens unit which is disposed in front of a first light source, and is configured as a lens unit which includes a rear end portion and a front end portion, and forms the first light distribution pattern which includes the first cut-off line when light from the first light source which entered the first lens unit is emitted from the front end portion of the first lens unit and is irradiated forward,
• the second lens unit is a lens unit which is disposed in front of a second light source, and is configured as a lens unit which includes a rear end portion and a front end portion, and forms the second light distribution pattern which includes the second cut-off line when light from the second light source which entered the second lens unit is emitted from the front end portion of the second lens unit and is irradiated forward,
• the first lens unit and the second lens unit are integrally molded so that the relative positional relationship between the first light distribution pattern and the second light distribution pattern becomes a predetermined positional relationship,
• the first light distribution pattern is a low beam light distribution pattern, an upper end edge of which includes the first cut-off line, and
• the second light distribution pattern is an Adaptive Driving Beam (ADB) light distribution pattern which includes the second cut-off line,
• the second lens unit includes an upper reflection surface and a vertical reflection surface, which are disposed between the rear end portion and the front end portion thereof,
• the rear end portion of the second lens unit includes an entrance portion through which the light from the second light source enters the second lens unit,
• a tip portion of the upper reflection surface and a tip portion of the vertical reflection surface each include a shade,
• the entrance portion, the upper reflection surface, the vertical reflection surface, and the front end portion of the second lens unit constitute an optical system configured to form the ADB light distribution pattern which includes, on the lower edge and on one side edge thereof, the second cut-off line specified by the shade of the upper reflection surface and the shade of the vertical reflection surface, when light partially shielded by the shade of the upper reflection surface and the shade of the vertical reflection surface and light internally reflected by the upper reflection surface and the vertical reflection surface, out of the light from the second light source which entered the second lens unit through the entrance portion, are emitted from the front end portion of the second lens unit and are irradiated forward.
