A lens body for a vehicle, the lens body configured to be disposed in front of a light source (20, 26) and configured to emit light forward from the light source (20, 26) along a forward/rearward reference axis (AX 40) extending in a forward/rearward direction of the vehicle, the lens body comprising: an incidence part configured to cause light from the light source (20, 26) to enter an inside of the lens body; a first reflecting surface configured to totally reflect the light entering from the incidence part; a second reflecting surface configured to totally reflect at least some of the light totally reflected by the first reflecting surface; and a light emitting surface configured to emit light forward passing through the inside, wherein the first reflecting surface comprises an elliptical spherical shape rotationally symmetrical with respect to a major axis (AX 44) extending in the forward/rearward direction, wherein the major axis (AX 44) of the first reflecting surface is inclined with respect to the forward/rearward reference axis (AX 40), wherein the elliptical spherical shape of the first reflecting surface constitutes first and second focal points (F1 44, F2 44), wherein the second focal point (F2 44) is disposed near the light source (20, 26) at a position rearward of the first focal point (F1 44) and lower than the first focal point (F1 44), wherein the second reflecting surface extends rearward from a point spaced a predetermined distance from the first focal point (F1 44) in an upward direction when the lens body is mounted in the vehicle, and among the light totally reflected by the first reflecting surface, light reaching the light emitting surface without being reflected by the second reflecting surface and light reaching the light emitting surface after being totally reflected by the second reflecting surface are emitted from the light emitting surface to be radiated forward. an incidence part configured to cause light from the light source (20, 26) to enter an inside of the lens body; a first reflecting surface configured to totally reflect the light entering from the incidence part; a second reflecting surface configured to totally reflect at least some of the light totally reflected by the first reflecting surface; and a light emitting surface configured to emit light forward passing through the inside, wherein the first reflecting surface comprises an elliptical spherical shape rotationally symmetrical with respect to a major axis (AX 44) extending in the forward/rearward direction, wherein the major axis (AX 44) of the first reflecting surface is inclined with respect to the forward/rearward reference axis (AX 40), wherein the elliptical spherical shape of the first reflecting surface constitutes first and second focal points (F1 44, F2 44), wherein the second focal point (F2 44) is disposed near the light source (20, 26) at a position rearward of the first focal point (F1 44) and lower than the first focal point (F1 44), wherein the second reflecting surface extends rearward from a point spaced a predetermined distance from the first focal point (F1 44) in an upward direction when the lens body is mounted in the vehicle, and among the light totally reflected by the first reflecting surface, light reaching the light emitting surface without being reflected by the second reflecting surface and light reaching the light emitting surface after being totally reflected by the second reflecting surface are emitted from the light emitting surface to be radiated forward.
