To allow light from one or one group of light sources to be used for a plurality of applications. A lens structure for a vehicle lamp includes a light transmitter and a reflective surface. The light transmitter is configured to transmit light in a predetermined horizontal direction. The reflective surface is provided at an upper portion of an end portion of the light transmitter in the predetermined horizontal direction. A direction perpendicular to the reflective surface is inclined toward a direction opposite to the predetermined horizontal direction from a direction directly downward. The reflective surface totally reflects the light travelling in the predetermined horizontal direction downward. The light transmitted from below the reflective surface in the light transmitter in the predetermined horizontal direction radiates in the predetermined horizontal direction, and the light reflected by the reflective surface illuminates a road surface.

Lens structure for vehicle lamp

A lens body includes a first lens portion and a second lens portion and is configured such that light from a light source exits through a first exit surface of the first lens portion after being partially blocked by a shade of the first lens portion, further exits through a second exit surface of the second lens portion, thereby forming a predetermined light distribution pattern by the shade, wherein the first exit surface is a surface for condensing the light from the light source that exits through the first exit surface with respect to a first direction and is configured as a semicircular cylinder surface, and the second exit surface is a surface for condensing the light from the light source that exits through the second exit surface with respect to a second direction orthogonal to the first direction and is also configured as a semicircular cylinder surface.
